Introduction i t c

Antibiotic resistance is now a major issue confronting healthcare u d providers and their patients. Changing antibiotic resistance patterns, o r t n rising antibiotic costs and the introduction of new antibiotics have I .

made selecting optimal antibiotic regimens more difficult now than ever 1 before. Furthermore, history has taught us that if we do not use antibiotics carefully, they will lose their efficacy. As a response to these challenges, the Johns Hopkins Antimicrobial Stewardship Program was created in July 2001. Headed by an Infectious Disease physician (Sara Cosgrove, M.D., M.S.) and an Infectious Disease pharmacist (Edina Avdic, Pharm.D., M.B.A), the mission of the program is to ensure that every patient at Hopkins on antibiotics gets optimal therapy. These guidelines are a step in that direction. The guidelines were initially developed by Arjun Srinivasan, M.D., and Alpa Patel, Pharm.D., in 2002 and have been revised and expanded annually. These guidelines are based on current literature reviews, including national guidelines and consensus statements, current microbiologic data from the Hopkins lab, and Hopkins’ faculty expert opinion. Faculty from various departments have reviewed and approved these guidelines. As you will see, in addition to antibiotic recommendations, the guidelines also contain information about diagnosis and other useful management tips. As the name implies, these are only guidelines, and we anticipate that occasionally, departures from them will be necessary. When these cases arise, we will be interested in knowing why the departure is necessary. We want to learn about new approaches and new data as they become available so that we may update the guidelines as needed. You should also document the reasons for the departure in the patient’s chart. Finally, please let us know if there are sections that you think could be improved, and also let us know if there is more information you would like to see included. Our goal is for the Antimicrobial Stewardship Program to be a useful service in optimizing antibiotic use at Hopkins. We welcome your thoughts and comments to 443-287-4570 (7-4570) or to: [email protected]. Sara E. Cosgrove, M.D., M.S.

Infections caused by anaerobes are often polymicrobial. • Gram-negative bacilli - Bacteroides spp., Prevotella spp., Porphyromonas spp., Fusobacterium spp. • Gram-negative cocci - Veillonella spp. • Gram-positive bacilli - Propionibacterium spp., Lactobacillus spp., Actinomyces spp., Clostridium spp. • Gram-positive cocci - Peptostreptococcus spp. and related genera Clinical diagnosis of anaerobic infections should be suspected in the presence of foul smelling discharge, infection in proximity to a mucosal surface, gas in tissues or negative aerobic cultures. Proper specimen 4.1 guidelines: Anaerobes Organism-specific collection is critical; refer to specimen collection guidelines at http://www.hopkinsmedicine.org/microbiology/specimen/index.html Treatment Notes Patients # Penicillin Amox/Clav Pip/Tazo Cefotetan Ertapenem Clindamycin Metronidazole

NOTE: Results in the table above are based on small number of isolates from sterile body sites, brain abscess and tissue by request and may be subject to sampling bias. • Surgical debridement of anaerobic infections is important because anaerobic organisms can cause severe tissue damage. • Ampicillin/sulbactam and Clindamycin are considered to be effective empiric therapy against Gram-positive anaerobes seen in infections

The Johns Hopkins microbiology laboratory utilizes standard reference methods for determining susceptibility. The majority of isolates are tested by the automated system. The minimum inhibitory concentration (MIC) value represents the concentration of the antimicrobial agent required at the site of infection for inhibition of the organism. The MIC of each antibiotic tested against the organism is reported with one of three interpretations S (susceptible), I (intermediate), or R (resistant). The highest MIC which is still considered susceptible represents the breakpoint concentration. This is the highest MIC which is 1 1 usually associated with clinical efficacy. MICs which are ⁄ 2– ⁄ 8 the

28 t breakpoint MIC are more frequently utilized to treat infections where r o antibiotic penetration is variable or poor (endocarditis, meningitis, p e osteomyelitis, pneumonia, etc.). Similarly, organisms yielding antibiotic r y g

MICs at the breakpoint frequently possess or have acquired a low-level o l o resistance determinant with the potential for selection of high-level i b o

expression and resistance. This is most notable with cephalosporins and r c Enterobacter spp., Serratia spp., Morganella spp., Providencia spp., i m

Citrobacter spp. and Pseudomonas aeruginosa. These organisms all e h possess a chromosomal beta-lactamase which frequently will be over- t g n expressed during therapy despite initial in vitro susceptibility. The i t e intermediate (I) category includes isolates with MICs that approach r p attainable blood and tissue levels, but response rates may be lower than r e t n fully susceptible isolates. Clinical efficacy can potentially be expected in I 1 body sites where the drug is concentrated (e.g., aminoglycosides and . beta-lactams in urine) or when a higher dose of the drug can be used 5 (e.g., beta-lactams). The resistant (R) category indicates the organism will not be inhibited by usually achievable systemic concentrations of the antibiotic of normal doses. NOTE: MIC values vary from one drug to another and from one bacterium to another, and thus MIC values are NOT comparable between antibiotics or between organisms.

Spectrum of antibiotic activity The spectrum of activity table is an approximate guide of the activity of commonly used antibiotics against frequently isolated bacteria. It takes into consideration JHH specific resistance rates, in vitro susceptibilities and expert opinion on clinically appropriate use of agents. For antibiotic recommendations for specific infections refer to relevant sections of the JHH Antibiotic Guidelines.

Interpretation of rapid diagnostic tests s e t c

The JHH microbiology lab performs rapid nucleic acid microarray testing i t s

on blood cultures growing Gram-positive organisms and peptide nucleic o n

acid fluorescence in situ hybridization (PNA-FISH) testing on blood g a i

cultures growing yeast. d d ® i Nucleic acid microarray testing (Verigine ) for Gram-positive p a r

cocci in blood cultures f • Detects and identifies the nucleic acids of 12 Gram-positive bacterial o n o i

genera/species and 3 resistance markers. t a • Bacteria species: S. aureus, Coagulase-negative staphylococci, S. t e r

lugdunensis, Staphylococcus spp. E. faecalis, E. faecium, S. pyogenes p r e

(group A streptococci), S. agalactiae (group B streptococci), S. t n pneumoniae, S. anginosus, Streptococcus spp. (e.g.,group C and G I 3 .

streptococci, viridans group streptococci, etc.), Listeria spp. 5 • Resistance markers: mecA, vanA, vanB • If S. aureus is mecA positive the organism is resistant to Methicillin and is reported as MRSA • If S. aureus is mecA negative the organism is susceptible to Methicillin and is reported as MSSA • If E. faecalis/faecium is vanA/B positive the organism is resistant to Vancomycin and is reported as VRE; note that all Vancomycin- resistant E. faecalis are susceptible to Ampicillin at JHH • Results of the test are reported within 3-4 hours after the blood cultures turn positive • Testing is performed only on the first positive blood culture • Testing is NOT performed on blood cultures growing more than one Gram positive organism but is performed on blood cultures growing both Gram positive and negative organisms • If the test is negative it will be reported as negative for the following organisms: Staphylococcus spp, Streptococcus spp., E. faecalis, E. faecium, Listeria spp.

PNA-FISH for yeast • If PNA-FISH shows C. albicans, most non-oncology patients without prior azole exposure can be treated with fluconazole. For more information see p. 108 and 124. • If PNA-FISH shows C. glabrata, treat with Micafungin until susceptibilities available. For more information see p. 108 and 124. • If PNA-FISH negative for C. albicans or C. glabrata, most cases can be treated as unspeciated candidemia, unless cryptococcus is suspected (send serum cryptococcal antigen).

6 • Severe PCN allergy: Ciprofloxacin 400 mg IV Q12H PLUS Metronidazole 500 mg IV Q8H Hospital-acquired infections OR patients with prior biliary procedures OR patients who are severely ill • Piperacillin/tazobactam 3.375 g IV Q6H OR • Severe PCN allergy: [Ciprofloxacin 400 mg IV Q12H OR Aztreonam 1 g IV Q8H] PLUS Metronidazole 500 mg IV Q8H Ϯ Vancomycin (see dosing section, p. 146) In severely ill patients with cholangitis and complicated cholecystitis, adequate biliary drainage is crucial as antibiotics will not enter bile in the presence of obstruction. Duration • Uncomplicated cholecystitis: treat only until obstruction is relieved. NO post-procedure antibiotics are necessary if the obstruction is successfully relieved. • Complicated cholecystitis: 4–7 days, unless adequate source control is not achieved. • Biliary sepsis: 4–7 days, unless adequate source control is not achieved.

TREATMENT NOTES Microbiology • Gram-negative rods – E. coli, Klebsiella spp., Proteus spp., P. aeruginosa (mainly in patients already on broad-spectrum antibiotics or those who have undergone prior procedures) • Anaerobes – Bacteroides spp., generally in more serious infections, or in patients with a history of biliary manipulations • Enterococcus spp. – treatment not always indicated; use clinical judgment • Yeast – rare Management • In cases of uncomplicated acute cholecystitis, antibiotics should be given until the biliary obstruction is relieved (either by surgery, ERCP, or percutaneous drain). 36 • Treatment of enterococci is usually not needed in mild/moderate s n o i

disease. t c e

• Yeast generally should be treated only if they are recovered from biliary f n cultures, not empirically. i l a n Reference: i Biliary tract infections: Drugs 1999;57(1):81-91. m o

38 Duration s n o i

For infected pancreatic necrosis, continue antibiotics for 14 days after t c e

source control is obtained. Continuation of antibiotics beyond this time f n places the patient at risk for colonization or infection with resistant i l a

organisms and drug toxicity. n i m o

TREATMENT NOTES d b

• Penicillins and cephalosporins penetrate poorly into the pancreas A 1 • Infection develops in 30–50% of patients with necrosis documented by . 6 CT scan or at the time of surgery. • Peak incidence of infection occurs in the 3rd week of disease • Prophylactic antibiotics have been associated with a change in the spectrum of pancreatic isolates from enteric Gram-negatives to Gram- positive organisms and fungi. • There is insufficient evidence to recommend selective gut decontamination in management of pancreatitis.

Peritonitis DEFINITIONS Primary peritonitis is spontaneous infection of the peritoneal cavity, usually associated with liver disease and ascites [spontaneous bacteria peritonitis (SBP)]. Secondary peritonitis is infection of the peritoneal cavity due to spillage of organisms into the peritoneum, usually associated with GI perforation. Tertiary peritonitis is a recurrent infection of the peritoneal cavity following an episode of secondary peritonitis.

Primary peritonitis/Spontaneous bacterial peritonitis (SBP) EMPIRIC TREATMENT • Ceftriaxone 1 g IV Q12H OR • Severe PCN allergy: Moxifloxacin 400 mg IV/PO Q24H (call ID or Antibiotic Management to discuss regimens for patients who have been taking fluoroquinolones for SBP prophylaxis). • Patients with serum creatinine >1 mg/dL, BUN >30 mg/dL or total bilirubin >4 mg/dL should also receive Albumin (25%) 1.5 g/kg on day 1 and 1 g/kg on day 3 (round to the nearest 12.5 g).

a Cirrhotic patients with gastrointestinal hemorrhage n i • Norfloxacin 400 mg PO BID for 7 days m o • Ceftriaxone 1 g IV Q24H can be used only if patient is NPO, then d b switch to Norfloxacin 400 mg PO BID once bleeding is controlled A

1 Non-bleeding cirrhotic patients with ascites . 6 • Norfloxacin 400 mg PO daily OR • TMP/SMX 1 DS PO once daily

TREATMENT NOTES Microbiology • Gram-negative rods (Enterobacteriaceae, esp. E. coli and K. pneumoniae), S. pneumoniae, enterococci, and other streptococci. • Polymicrobial infection should prompt suspicion of GI perforation. Diagnostic criteria • 250 PMN per mm3 of ascitic fluid. • Positive culture with < 250 PMN should prompt repeat tap. If PMN > 250 OR culture remains positive, patient should be treated. Follow-up • Consider repeat paracentesis after 48 hours of therapy. • Consider changing antibiotics if ascites fluid PMN has not dropped by 25% after 48 hours and/or patient is not clinically responding. Notes on prophylaxis against SBP • All patients with cirrhosis and upper GI bleed should receive prophylaxis for 7 days (50% develop SBP after bleed). • Patients who get SBP should get lifelong prophylaxis to prevent future episodes (40–70% risk of recurrence in 1 year). • Prophylaxis with Norfloxacin should be considered for those with low protein concentrations in ascites (< 10 g/L) or immunosuppression while patient is in hospital.

41 s TREATMENT NOTES n o i t • Causative agents for small bowel, colon, appendix: anaerobes (esp. c e

f B. fragilis), Enterobacteriaceae (esp. E. coli, K. pneumoniae, n i Enterobacter spp., Proteus spp.); infections usually polymicrobial. l a

n • Pathogens causing tertiary peritonitis are variable and are often i

m resistant to or not covered by the initial antimicrobial regimen; thus, a o d change in antimicrobials is advised. b

A • A change in antimicrobials therapy should be considered in patients 1 . with hospital-acquired infections who are already on antimicrobials. 6 • Treatment of enterococci remains controversial but should be considered in critically ill or immunocompromised patients or when they are a dominant organism in the peritoneal culture. • Treatment of Candida spp. is generally indicated only when they are recovered from blood or are a dominant organism in the peritoneal culture in critically ill or immunocompromised patients. • Postoperative antibiotics for appendicitis are unnecessary unless there is clinical evidence of peritonitis, abscess, or gangrene. • Antibiotics are adjunctive to source control, which is an absolute necessity. • Lack of source control is defined as on-going contamination and/or an undrained collection of infection.

Peritonitis related to peritoneal dialysis

EMPIRIC TREATMENT Mild to moderate illness: intraperitoneal therapy is preferred in most cases. Anuric patient • Cefazolin 15 mg/kg in one bag Q24H (1 g if patient < 65 kg) PLUS • Gentamicin 2 mg/kg in one bag loading dose, then Gentamicin 0.6 mg/kg in one bag Q24H Patient with urine output > 100 mL/day • Ceftazidime 1 g in one bag Q24H Severe illness: systemic therapy is preferred. • FIRST DOSE: Vancomycin (see dosing section, p. 146) IV PLUS ONE of the following: [Gentamicin 2 mg/kg IV OR Ceftazidime 1 g IV OR Ciprofloxacin 400 mg IV] • MAINTENANCE DOSE: Dose per drug levels and/or renal function (See dosing section p. 141, 146, and 150) Duration of tailored therapy: 10–14 days

TREATMENT NOTES o i t

Microbiology c e f

• Most cases caused by contamination of the catheter n i l

• Cultures may be negative in 5–20% a n • Gram-positive cocci (S. aureus, coagulase-negative staphylococci, i m

Enterococcus spp.), Gram-negative rods, yeast (much less common) o d b

Diagnosis A 1 • All patients with suspected PD-related peritonitis should have PD fluid . 6 sampled for cell count, differential, gram stain, culture AND amylase. WBC > 100/mm3 with > 50% PMN suggests infection. • Elevated amylase suggests pancreatitis or bowel perforation. • In symptomatic patients with cloudy fluid accompanied by abdominal pain and/or fever, empiric treatment should be started given the high likelihood of infection. • In symptomatic patients with clear fluid, another PD fluid exchange, with a dwell time of at least 2 hours, should be sampled. The decision to start empiric therapy in these cases will depend on how sick the patient appears. • In asymptomatic patients with cloudy fluid, it is reasonable to delay therapy pending the results of cell count, gram stain, and culture.

Other indications for oral Vancomycin use • No response to oral Metronidazole after 5 days of therapy • Second episode of recurrent disease • Patients with significant side effects to Metronidazole • Patients who are pregnant • Consider in patients > 80 years given reports of increased morbidity from CDI.

45 ) I Duration D C

( • 10–14 days n o i Approach to patients who need to continue broad spectrum t c antibiotic therapy e f n i • Determine the shortest possible course of antibiotic therapy. e l

i • Replace the antibiotic that induced CDI, particularly cephalosporins, c i f Clindamycin, and fluoroquinolones. f i d • If the inducing agent is replaced and the CDI resolves, complete a m standard 10-14 day course of CDI therapy; there is no need to extend u i d i CDI therapy until the end of the course of antibiotic therapy. r t s • If the inducing agent cannot be stopped or replaced, consider o l

C continuing CDI therapy until the end of the course of antibiotic therapy 2

. (data are limited); CDI therapy should not be continued beyond the end 6 of antibiotic therapy if the patient remains asymptomatic. Recurrent disease • Resistance to Metronidazole or Vancomycin has not been documented conclusively. • Recurrent disease after a complete course of therapy occurs in ~ 25% of patients. Relapse is due to failure to eradicate spores (60%) or acquisition of a new strain (40%). Document recurrent disease with repeat stool testing. • First recurrence should be treated the same as the initial episode; severe disease should be treated with Vancomycin. • Second recurrence should be treated with Vancomycin taper followed by pulse dosing. • If serious or multiple recurrences, consult ID.

Vancomycin taper regimen 125 mg 4 times daily x 10–14 days 125 mg BID X 7 days 125 mg daily X 7 days 125 mg every 2–3 days for 2–8 weeks (pulse dosing)

NOTES Management • Surgical intervention for colectomy should be considered early if the patient is clinically unstable secondary to CDI. • Treatment of CDI should be continued in patients who have a subtotal colectomy with preservation of the rectum. • Most patients with severe CDI should undergo abdominal CT to rule out toxic megacolon or pancolitis.

46 ) • Do NOT send follow-up C.difficile PCR to document resolution of I D C

disease. (

• Do not use antimotility agents. n o i t

• Stop proton pump inhibitors (PPIs) whenever possible as data suggest c e PPIs increase the risk of CDI. f n i

• The offending antimicrobial agents should be discontinued. If e l i c

antimicrobials are still required, it is best to avoid cephalosporins, i f f i

Clindamycin, and fluoroquinolones. d

• Prophylactic use of oral Metronidazole or Vancomycin in patients m u i

receiving antimicrobial therapy for treatment of underlying infection d i r (other than CDI) is not recommended and may increase the patient’s t s o risk for CDI. l C 2

Infection control . • Patients with CDI should be placed in contact precautions and single 6 rooms for the duration of hospitalization. • Use soap and water rather than alcohol-based hand gel upon exiting the room of a patient with CDI.

Management of catheter-related n o i t

bloodstream infections (CR-BSI) c e f n

Diagnosis i

• If there is more than minimal erythema or ANY purulence at the exit m a e

site, the catheter is likely infected. It should be removed and replaced r t at a different site. s d o

• Two sets of blood cultures should be drawn with AT LEAST one (and o l preferably both) from peripheral sites. Blood cultures drawn through b d e

non-tunneled catheters are more likely to yield contaminants. One set t a l

of cultures may be drawn through a catheter if it is tunneled. e r -

• The utility of cultures of the catheter tip itself is not well defined, and r e t

should ONLY be sent when there is a clinical suspicion of infection, NOT e h routinely when lines are removed. They MUST be accompanied by two t a

sets of blood cultures obtained as detailed above. C 5 • Technique: The exit site should be cleaned with alcohol. The . 6 catheter should be grasped a few centimeters proximal to the exit site. A 5 cm segment of catheter including the tip should be cut off with sterile scissors and placed in a sterile container. • In instances where the blood and catheter tip are cultured at the same time and the blood cultures are negative but the catheter tip culture is positive, antibiotics are generally not recommended, even for patients with valvular heart disease or immunosuppression. • The exception is patients whose catheter tips grow S. aureus and have negative blood cultures. These patients should receive 5–7 days of antibiotics. • All patients should be followed closely, and repeat cultures should be sent if clinically indicated. • When a catheter-related BSI is associated with catheter dysfunction, consider the possibility of suppurative thrombophlebitis. EMPIRIC TREATMENT • Vancomycin (see dosing section, p. 146) ± Cefepime 1–2 g IV Q8H (use higher dose if pseudomonas suspected) OR • Severe PCN allergy: Vancomycin (see dosing section, p. 146) ± [Ciprofloxacin 400 mg IV Q8H OR Aztreonam 2 g IV Q8H] ± Tobramycin (see dosing section, p. 141) Empiric treatment – Gram-positive cocci in clusters in 2 or more sets of blood cultures • Vancomycin (see dosing section, p. 146)

NOTE: Can be contaminants. Draw repeat cultures to confirm before r e t starting treatment. 100% of E. faecalis blood isolates at JHH are e h t

susceptible to Ampicillin, which should be used unless the patient has a a PCN allergy. C 5 .

• Ampicillin 2 g IV Q4H 6 OR • PCN allergy: Vancomycin (see dosing section p. 146) Duration: 7–14 days Enterococcus faecium NOTE: Can be contaminants. Draw repeat cultures to confirm before starting treatment. The majority (81%) of E. faecium blood isolates at JHH are resistant to Vancomycin. If the isolate is susceptible to Ampicillin or Vancomycin, these agents should be used preferentially at the doses listed above for E. faecalis bacteremia. • Linezolid 600 mg IV/PO Q12H OR • Daptomycin 8–12 mg/kg IV Q24H TREATMENT NOTES • Consider echocardiogram if there is persistent bacteremia (> 3 days) on antibiotics. • Do not use Gentamicin if the lab reports no synergy with a cell wall agent. • If synergy is present, Gentamicin should be added to Ampicillin or Vancomycin in the treatment of endocarditis; however, the addition of Gentamicin does not appear to change outcomes in CR-BSI caused by Enterococcus in the absence of endocarditis. • Do not use Gentamicin with Linezolid or Quinupristin/dalfopristin given lack of supportive evidence for synergy.

6 Microbiology – most common pathogens: Coagulase-negative staphylococci, Enterococci, S. aureus, Gram-negative bacilli, Candida species Catheter salvage • Catheter removal is STRONGLY recommended for infections with S. aureus, yeast and Pseudomonas, as the chance of catheter salvage is low and the risks of ongoing infection can be high. • Catheters associated with tunnel infections CANNOT be salvaged and should be removed. • Catheter salvage can be considered in CR-BSIs caused by coagulase- negative staphylococci if the patient is clinically stable. • When catheter salvage is attempted, antibiotics should be given through the infected line. • Duration of treatment for catheter salvage is similar to duration of treatment when the catheter is removed unless otherwise noted above. • Antibiotic or ethanol lock therapy, in which an antibiotic or ethanol is infused into the catheter and left in place, can be considered in the treatment of tunneled catheter infections due to less virulent pathogens such as CoNS and some Gram-negatives. Call the Antimicrobial Stewardship Program (7-4570) for details.

t Major criteria i d

r Microbiologic a c • Two separate blood cultures positive for a typical organism: viridans o d streptococci, S. bovis, HACEK, S. aureus, Enterococcus spp. n

E • Persistent bacteremia with any organism as evidenced by: 2 positive 6 .

6 blood cultures drawn at least 12 hours apart OR 3/3 positive blood cultures with at least 1 hour between the first and last OR the majority of more than 4 cultures positive from any time period. • Positive Coxiella burnetti () culture or serology. Echocardiographic (TEE strongly recommended for prosthetic valve) • Vegetation (on valve or supporting structure OR in path of regurgitant jet) • Abscess • New dehiscence of prosthetic valve Physical exam • NEW regurgitant murmur (worsening of old murmur is NOT sufficient) Minor criteria • Predisposing condition: previous endocarditis, injection drug use, prosthetic valve, ventricular septal defect, coarctation of the aorta, calcified valve, patent ductus, prolapse with regurgitation, IHSS or other valvular heart disease • Fever ≥ 38.0°C (100.4°F) • Embolic events: arterial or pulmonary emboli, conjunctival hemorrhage, retinal hemorrhage, splinter hemorrhage, intracranial hemorrhage, mycotic aneurysm • Immunologic phenomenon: Osler nodes, glomerulonephritis, positive rheumatoid factor • Positive blood cultures that don’t meet criteria above OR serologic evidence of active infection with an organism known to cause endocarditis BUT single positive cultures for coagulase-negative staphylococci are NOT considered even a minor criterion

TREATMENT NOTES P 7 Microbiology—staphylococci in 70-80% of cases (~50% coagulase- . 6 negative staphylococci and ~50% S. aureus) Management • If blood cultures are positive or endocarditis is suspected patients should undergo transesophageal echocardiography (TEE) • Complete extraction recommended for patients with pocket infection and/or valvular or lead endocarditis • At the time of extraction, tissue (rather than swabs) from the generator pocket should be sent for Gram-stain and culture and lead tips should be sent for culture. • Note that because leads are extracted through an open generator pocket, they may become contaminated by the infected pocket; therefore, positive lead cultures are not always indicative of lead endocarditis in patient with negative blood cultures. • Blood cultures should be obtained after device removal. • Device reimplantation should be on the contra-lateral side whenever possible. • Complete extraction is strongly recommended in all patients presenting with S. aureus bacteremia and no other source • Complete extraction should be considered in patients with persistent positive blood cultures with other organisms (e.g. coagulase-negative staphylococci, enterococci, Gram-negative bacilli) on a case-by-case basis. • Complete device and lead removal is recommended for patients with valvular endocarditis. • Antimicrobial prophylaxis is NOT recommended for dental or other invasive procedures following placement

hospitalized patients c e f n EMPIRIC TREATMENT i y r a

Patient NOT in the ICU n • Ceftriaxone 1 g IV Q24H PLUS Azithromycin 500 mg IV/PO once daily o m l

OR u P

• Moxifloxacin 400 mg IV/PO Q24H 0 1 .

In non-critically ill patients, consider switch to oral agents as soon as 6 patient is clinically improving and eating (see next page for oral options and doses). Patient in the ICU Not at risk for infection with Pseudomonas (see risks below) • Ceftriaxone 1 g IV Q24H PLUS Azithromycin 500 mg IV Q24H OR • PCN allergy: Moxifloxacin 400 mg IV Q24H At risk for infection with Pseudomonas (see risks below) • Cefepime 1 g IV Q8H PLUS Azithromycin 500 mg IV Q24H OR • Piperacillin/tazobactam 4.5 g IV Q6H PLUS Azithromycin 500 mg IV Q24H OR • Severe PCN allergy: Moxifloxacin 400 mg IV Q24H PLUS Aztreonam 2 g IV Q8H • Sputum gram stain may help determine if Pseudomonas is present. • Narrow coverage if Pseudomonas is NOT present on culture at 48 hours. • Risks for Pseudomonas: prolonged hospital or long-term care facility stay (≥ 5 days), structural lung disease (e.g. CF, bronchiectasis), steroid therapy, broad-spectrum antibiotics for > 7 days in the past month, AIDS (CD4 <50), granulocytopenia (ANC <500)

DIAGNOSIS • Immunocompetent patients MUST have a chest X-ray infiltrate to meet diagnostic criteria for pneumonia. • Sputum and blood cultures should be sent on all patients admitted to the hospital BEFORE antibiotics are given. • S. pneumoniae urine antigen should be obtained in all patients with CAP. It has specificity of 96% and positive predictive value of 88.8-96.5%.

Respiratory virus diagnosis and management n e m

Diagnosis e g

• Respiratory virus testing should be obtained year round on any patient a n for whom there is a clinical suspicion of respiratory virus infection. In a m

addition, during influenza and RSV season testing should be obtained in d n

patients with: a s i

• Fever and influenza-like symptoms (sore throat, myalgia, arthralgia, s o

cough, runny nose and/or headache) n g

• Suspected bronchiolitis or pneumonia a i • COPD/asthma exacerbation or respiratory failure d s u

• Unexplained CHF exacerbation r i • Elderly patients with unexplained new onset malaise v y r

• Pregnant patients with unexplained respiratory symptons o t a

• Nonspecific symptoms and a documented exposure to someone with r i p

a respiratory illness s e

• Respiratory virus testing at JHH R

• Standard panel for immunocompetent hosts: RSV, influenza A/B, 1 1 .

adenovirus, human metapneumovirus, and parainfluenza 1-3. 6 • One NP swab should be sent • DFA is performed first followed by shell vial culture if DFA negative • Extended panel for immunocompromised hosts: rhinovirus and parainfluenza 4 in addition to the viruses listed above • Two NP swabs in two separate transport tubes • DFA is performed first followed by multiplex PCR if DFA negative Treatment of influenza in inpatients • Empiric treatment of adult inpatients should be considered in the following situations during influenza season: • Patients with fever and influenza-like symptoms, unexplained interstitial pneumonia or new respiratory failure without an obvious non-influenza cause • Duration: 5 days unless an alternative diagnosis is identified, PCR is negative, or shell vial culture is negative and influenza is not suspected • Treatment should be initiated in all patients who are admitted to the hospital and have influenza with symptom onset in the past 48-72 hours • The utility of treatment of patients who present late in the course of disease is uncertain and the decision to treat these patients can be made on a case-by-case basis • Antiviral choice is dependent on the susceptibility of circulating strains which may vary from season to season (see www.hopkinsmedicine.org/amp for current recommendations) Infection control • All individuals with suspected respiratory virus infection should be placed on droplet precautions. A private room is required, unless

n patients are cohorted. When outside of their room (i.e. during e transport) patients should wear a mask. m e

g • All health care workers must receive the influenza vaccine yearly. a n • Personnel with direct patient care or working in clinical areas who have not a

m received the influenza vaccine are required to wear a mask when within d 6 feet of a patient. The dates of the mask requirement are determined by n a HEIC and based on influenza activity in the local community. s i s • No one with fever may work until at least 24 hours after fever has o n

g resolved (without antipyretics). All personnel with respiratory symptoms a i and fever must call or report to their supervisor and must call d s Occupational Health Services (OHS). u r i

v • Afebrile employees who have respiratory systems must wear a surgical y r mask during patient contact (≤ 6 ft). o t

a • If an unvaccinated HCW is exposed to a patient with documented r i

p influenza who was not on Droplet Precautions, notify HEIC and call s e Occupational Health Services (OHS) immediately. OHS will decide R

1 whether to recommend post-exposure prophylaxis. 1 . 6 Anti-influenza agents Medication Adult dosing Side effects Notes Oseltamivir Treatment: Common: nausea, Dose adjustment 75 mg PO twice a day vomiting needed for GFR for 5 days <30 mL/min Prophylaxis: Severe: 75 mg PO once a day hypersensitivity, neuropsychiatric Zanamivir Treatment: Common: diarrhea, Should NOT be used 10 mg (2 oral inhalations) nausea, cough, in patients with twice daily for 5 days headache, and chronic underlying Prophylaxis: dizziness airway diseases 10 mg (2 oral inhalations) once a day Severe: bronchospasm, hypersensitivity, laryngeal edema, facial swelling Amantadine Treatment/Prophylaxis: Common: nervousness, Dose adjustment 100 mg PO twice a day anxiety, difficulty needed for GFR or 200 mg once daily concentrating, Յ50 mL/min lightheadedness, nausea Severe: hypersensitivity, neuropsychiatric Rimantadine Treatment/Prophylaxis: Common: nervousness, Dose adjustment Ͻ 65 y/o 100 mg PO anxiety, difficulty needed for GFR twice a day concentrating, Յ 10 mL/min and Ն 65 y/o 100 mg PO lightheadedness, severe hepatic once daily nausea dysfunction Severe: hypersensitivity, neuropsychiatric

out active TB; cultures may yield 1 .

results after 6–8 weeks 6 Tuberculin skin test (TST) Intradermal injection of purified protein derivative (PPD) and measurement of induration diameter in 48–72 hours for diagnosis of latent TB infection (also positive in most active TB cases). Criteria for a positive test are: • Ն 5 mm – high risk of developing active TB (e.g. HIV infection, close contact of TB case, immunocompromised) • Ն 10 mm – other risk factors for TB infection (HCW, IDU, DM) • Ն 15 mm – no risk factors for TB Latent TB infection (LTBI) Previous infection with TB that has been contained by the host immune response • Patients may have a positive TST, a positive interferon gamma release assay, or suggestive radiographic findings such as calcified granulomata or minimal apical scarring, but do not have symptoms of active TB disease • Not infectious and does not require isolation Active TB disease Active replication of M. tuberculosis causing pulmonary or extrapulmonary symptoms and/or signs. • Confirmed by positive AFB smear, MTD test or culture • Requires airborne isolation

87 n When to suspect active TB disease o i t c

e High-risk individuals f n i • Recent exposure to a person with known TB; history of a positive TST; )

B HIV infection; injection or non-injection drug use; foreign birth or T (

s residence in a region in which TB incidence is high; residents and i s

o employees of high-risk congregate settings (e.g. prisons); membership l u in a medically underserved, low-income population; anti-TNF alpha c r e therapy b u T Clinical syndromes 2 1

. • Cough of Ն2 wk duration, with at least one additional symptom, 6 including fever, night sweats, weight loss, or hemoptysis • Any unexplained respiratory illness of Ն2 wk duration in a patient at high risk for TB • Any patient with HIV infection and unexplained cough and fever • Any patient on anti-TNF alpha therapy with unexplained fever • Community-acquired pneumonia which has not improved after 7 days of appropriate treatment • Incidental findings on chest radiograph suggestive of TB (even if symptoms are minimal or absent) in a patient at high risk for TB Radiographic findings • Primary TB (often unrecognized): Can resemble CAP and involve any lobes; hilar adenopathy, pleural effusions are common; cavitation is uncommon. Findings often resolve after 1–2 months. These are common findings in patients with advanced HIV infection and TB. • Reactivation TB: Infiltrates with or without cavitation in the upper lobes or the superior segments of the lower lobes; hilar adenopathy is variable; CT scan may have “tree-in-bud” appearance. Diagnosis • Patients with characteristic syndromes and radiographic findings should have expectorated sputum obtained for AFB smear and culture. • Sensitivity of AFB smear on expectorated sputum is 50–70%; it is lower in HIV+ patients. Morning expectorated sputum, induced sputum, bronchoscopy have higher sensitivity. AFB culture of lower respiratory tract specimens is considered the gold standard. • AFB smear and culture should be obtained regardless of CXR findings in patients with high clinical suspicion, HIV infection or other immunocompromised states. CXR is normal in approximately 10% of HIV-infected patients with pulmonary TB. Infection control Airborne precautions are required in the following cases: • Suspicion of disease sufficiently high to warrant obtaining sputum AFB smear/culture as described above 88 • Positive AFB smear or culture until diagnosis of TB vs. NTM is n o i t

confirmed c e • Known active pulmonary or laryngeal TB (if patient is currently on TB f n i

treatment, consult with HEIC and patient’s local health department to ) B T

obtain treatment history in order to determine if infectious at the time ( s of current hospitalization; in meantime airborne precautions are i s o required) l u c r e b u

Smear Smear Smear positive negative positive

Mycobacterium MTD Obtain 2nd Smear Tuberculosis negative and 3rd negative Direct Test (MTD) specimen* automatically performed Smear If pt highly suspected positive for TB, await culture result and continue isolation. Otherwise, MTD test CALL HEIC 5-8384 to DISCONTINUE ISOLATION MTD performed positive

MTD MTD positive negative

Continue isolation until at least 14 days of therapy CALL HEIC AND clinical improvement 5-8384 TO AND 3 consecutive negative DISCONTINUE smears (Call HEIC for ISOLATION approval to D/C isolation on smear positive patient.)

*One expectorated sputum must be a first morning specimen; samples should be collected at least 8 hours apart.

89 n TREATMENT o i t c

e Active TB f n i • ID consult is strongly recommended )

B • Therapy should be initiated for patients with positive AFB smear and T (

s clinical findings consistent with active TB. i s

o • Therapy should be considered for patients with negative AFB smears l u when suspicion of TB is high and no alternate diagnosis exists. Multiple c r e specimens should be obtained for culture prior to treatment. b u • Four drugs are necessary for initial phase (2 months). T

2 • Isoniazid (INH) 300* mg (5 mg/kg) PO daily 1 .

6 • Rifampin (RIF) 600* mg (10 mg/kg) PO daily • Pyrazinamide (PZA) 1000 mg PO daily (40–55 kg) OR 1500 mg PO daily (56–75 kg) OR 2000* mg PO daily (76–90 kg) • Ethambutol (EMB) 800 mg PO daily (40–55 kg) OR 1200 mg PO daily (56–75 kg) OR 1600* mg PO daily (76–90 kg) *Max dose regardless of weight. • Pyridoxine 25 mg PO daily is recommended to prevent INH associated peripheral neuropathy in patients with HIV, malnutrition, alcohol abuse, diabetes mellitus, renal failure or in pregnant or breastfeeding women. Latent TB • Treatment for latent tuberculosis should not be started in the hospital setting without a clear follow-up plan. Drug toxicity and monitoring • Isoniazid: asymptomatic elevation in hepatic enzymes, serious and fatal hepatitis, peripheral neurotoxicity • Rifampin: orange discoloration of body fluids, hepatotoxicity, pruritis with or without rash • Pyrazinamide: hepatotoxicity, nongouty polyarthralgia, asymptomatic hyperuricemia, acute gouty arthritis • Ethambutol: retrobulbar and peripheral neuritis • Monitoring: baseline hepatic transaminases, bilirubin, alkaline phosphatase, creatinine and CBC are recommended for all adults initiating TB treatment. Monthly hepatic panel is recommended for patients with baseline abnormalities, history of liver disease or viral hepatitis, chronic alcohol consumption, HIV, IVDU, pregnancy or immediate post-partum state or those taking other potentially hepatotoxic medications.

TREATMENT NOTES U 5

• Remove the catheter whenever possible 1 .

• Replace catheters that have been in Ն 2 weeks if still indicated 6 • Prophylactic antibiotics at the time of catheter removal or replacement are NOT recommended due to low incidence of complications and concern for development of resistance. • Catheter irrigation should not be used routinely

Treatment of Enterococci • Almost all E. faecalis isolates are susceptible to Amoxicillin 500 mg PO TID OR Ampicillin 1 g IV Q6H and should be treated with these agents. For patients with PCN allergy: Nitrofurantoin ( Macrobid®) 100 mg PO Q12H (do NOT use in patients with CrCl < 50 mL/min). • E. faecium (often Vancomycin resistant) • Nitrofurantoin (Macrobid®) 100 mg PO Q12H if susceptible (do NOT use in patients with CrCl Ͻ 50 mL/min). • Tetracycline 500 mg PO Q6H if susceptible • Fosfomycin 3 g PO once (if female without catheter or catheter is removed; ask the micro lab for susceptibility) • Linezolid 600 mg PO BID OR Fosfomycin 3 g PO every 2–3 days (max 21 days) if complicated UTI or catheter can not be removed

Renal excretion/concentration of selected antibiotics Good (≥60%): aminoglycosides, Amoxicillin, Amoxicillin/clavulanate, Fosfomycin, Cefazolin, Cefepime, Cephelexin, Ciprofloxacin, Colistin, Ertapenem, Trimethoprim/sulfamethoxazole, Vancomycin, Amphotericin B, Fluconazole, Flucytosine Variable (30-60%): Cefpodoxime, Linezolid (30%), Doxycycline (29–55%), Ceftriaxone, Tetracycline (~60%) Poor (<30%): Azithromycin, Clindamycin, Moxifloxacin, Oxacillin, Tigecycline, Micafungin, Posaconazole, Voriconazole

Filamentous fungi p o r t u

TREATMENT e n n i

Aspergillus spp. s l a i

Initial therapy b o • Voriconazole 6 mg/kg IV/PO Q12H times two doses then 4 mg/kg r c i

IV/PO Q12H (see Voriconazole guidelines, p. 17, for more information). m i t

OR n a

• AmBisome® 5mg/kg IV Q24H f o e

NOTES: s u

• Voriconazole is considered by many to be the first-line treatment of r o suspected filamentous fungal infections in the immunocompromised f s e

host as most of these infections are caused by Aspergillus species. n i l

Although the data are limited, Voriconazole appears more effective e d i

than Amphotericin for this very serious infection. u G

• Combination antifungal therapy is not recommended for empiric 8 1 therapy of aspergillosis. . 6 Treatment failure • The Oncology/Transplant ID consult service (#4-0242) should be involved in these cases to assist in antifungal selection and eligibility for ongoing clinical trials. • Treatment failure defined as: • Persistent fever beyond 96 hours • Worsening clinical status at ANY time after starting therapy defined as: hypotension, worsening respiratory status, evidence of embolization • Worsening radiologic findings • Patients receiving Voriconazole should be appropriately dosed using actual body weight (mg/kg) and have therapeutic levels before being considered treatment failures. See p. 17 for dosing and therapeutic monitoring. • Micafungin PLUS [Voriconazole OR AmBisome®] NOTE: There is no convincing evidence to suggest that any of the agents would be superior in patients who fail to respond to the first agent. In vitro data suggest that Micafungin in combination with Voriconazole may be the most effective approach in those who fail to respond to Voriconazole alone.

Approach to the patient with a history g r e l of penicillin allergy l a n i l

Penicillin reactions – Incidence l i c • 80-90% of patients who report they are “allergic” to PCN actually have i n e

negative skin tests and are not at increased risk of an allergic reaction. p f

• Penicillin reactions of some type occur in 0.7 to 10% of all patients o y

who get the drug. r o t

• BUT: The incidence of anaphylactic reactions is 0.004% to 0.015%. s i • Rates of cross-reaction allergies to cephalosporins are unknown but h a

thought to be low. h t i

• Rates of PCN and carbapenem skin test cross reactivity are 47%, w t

although clinical rates of hypersensitivity reactions in patients with n e i reported PCN allergy who receive carbapenems are 9–11%. t a • Cross reactions to monobactams (Aztreonam) do NOT appear to occur. p e h t

Penicillin skin testing o t

• When done correctly, is highly predictive of serious, anaphylactic reactions. h c

• Patients with a negative skin test are NOT at risk for anaphylactic reactions. a o r

• Rarely, skin test negative patients may get mild hives and itching p p

following penicillin administration but these RESOLVE with continued A 1 treatment. . • Skin tests cannot predict dermatologic or GI reactions or drug fevers. 7 • Skin testing is now available at JHH. Please consult Allergy and Immunology. Penicillin reactions—Types • Immediate (type 1) – Anaphylaxis, hypotension, laryngeal edema, wheezing, angioedema, urticaria • Almost always occur within 1 hour of administration. Hypotension always occurs soon after administration • Can be predicted by skin tests • Accelerated – Laryngeal edema, wheezing, angioedema, urticaria (NOT hypotension) • Occur within 1-72 hours of administration • Can be predicted by skin tests • Late – Rash (maculopapular or morbilliform or contact dermatitis), destruction of RBC, WBC, platelets, serum sickness • Almost always occur after 72 hours of administration • Rashes sometimes go away despite continued treatment • Maculopapular and morbilliform rashes DO NOT progress to Stevens-Johnson syndrome • Late reactions are NOT predicted by skin tests • Stevens-Johnson Syndrome – exfoliative dermatitis with mucous membrane involvement

127 y • Almost always occur after 72 hours of administration g r e

l • NOT predicted by a history of rash OR by skin tests l a n i Approach to the patient with reported penicillin allergy l l i c i

n • Brief, focused history can be VERY helpful. e p • Questions to ask: f o 1. How long after beginning penicillin did the reaction occur? y r 2. Was there any wheezing, throat or mouth swelling, urticaria? o t s i 3. If a rash occurred, what was the nature of the rash? Where was it h

a and what did it look like? h t 4. Was the patient on other medications at the time of the reaction? i w 5. Since then, has the patient ever received another penicillin or t n

e cephalosporin (ask about trade names like: Augmentin, Keflex, i t a Trimox, Ceftin, Vantin)? p

e 6. If the patient received a beta-lactam, what happened? h t o t Interpreting the history of the patient reporting penicillin allergy h c a • ANY patient who has a history consistent with an immediate o r

p reaction (laryngeal edema, wheezing, angioedema, urticaria) p

A SHOULD NOT receive beta-lactams without undergoing skin 1

. testing first EVEN IF they have received beta-lactams with no 7 problems after the serious reaction. • Patients who report non-anaphylactic reactions and have received other penicillins without problems DO NOT have penicillin allergy and are not at increased risk for an allergic reaction compared to the general population. • Patients who report non-anaphylactic reactions and have received cephalosporins can get cephalosporins but not necessarily PCNs. • Patients who report a history of a non-urticarial rash that is NOT consistent with Stevens-Johnson syndrome (target lesions with mucous membrane inflammation) and developed after ≥ 72 hours of penicillin are not at increased risk for an adverse reaction. They should, however, be watched closely for development of rashes. • Patients who report reactions consistent with serum sickness (rare) can receive either penicillins or cephalosporins with careful monitoring for recurrence. • Patients who report GI symptoms (diarrhea, nausea) probably do not have penicillin allergy and do not appear to be at increased risk for an adverse reaction. They should be closely observed for recurrent symptoms and be given supportive therapy if they occur. References: JAMA 2001;285:2498. Use of carbapenems in patients with PCN allergy: J Antimicrob.

Combination therapy or “double-coverage” of e g a Gram-negative bacterial infections r e v o

Reasons to consider combination therapy c e l

Synergy b u • Occurs when inhibitory or bactericidal activity of combination therapy is o D greater than would be expected from the sum of the activities of the “ 2 .

individual agents 7 • Synergy for Gram-negative infections is of major value only when the bacterium is resistant to one or both of the drugs in the combination. • Synergy has been best established for beta-lactam and aminoglycoside combinations. • Synergy between other drug combinations is less predictable and has unclear clinical significance. Prevention of emergence of resistance • Emergence of resistance on therapy is uncommon, occurring in 5–10% of infections treated. • Emergence of resistance to cephalosporins while on therapy with these agents occurs in ~20% of patients infected with Enterobacter spp., and are best avoided in these patients if other options are available. • Emergence of resistance is more common in pneumonia, intraabdominal infections with poor source control and osteomyelitis due to decreased antibiotic penetration at these sites; attention should be given to appropriate dosing in these patients. • The addition of additional agents may lead to increased toxicity from adverse drug reactions.

Broadening empiric coverage in the event that the causative organism is resistant to one agent • Should be considered in patients with life-threatening infections (ventilator-associated pneumonia, sepsis). • Second agent should offer additional coverage and generally will be an aminoglycoside at JHH. • Coverage MUST be narrowed based on culture results; negative cultures can be used to rule out infections with most organisms.

Data regarding combination therapy • An early study by Hilf suggested that combination therapy was superior to monotherapy in patients with Pseudomonas bacteremia BUT 84% of monotherapy patients received inadequate monotherapy with an aminoglycoside. Five more recent studies have not shown a difference in mortality when patients received appropriate monotherapy for Pseudomonas bacteremia.

Hand hygiene E l a

• Hand hygiene measures are the single most important strategy for t i p

preventing healthcare-associated infections. s o

• If hands are not visibly soiled, then alcohol-based hand sanitizers are H 1

recommended for cleaning. If hands are visibly soiled, wash hands with . soap and water for at least 15 seconds. 8 • Hand hygiene is required upon entering a patient room, upon exiting, between patients in a semi-private room, and other times per hospital policy. • Use soap and water upon exiting the room of a patient with C. difficile infection. • No artificial fingernails are permitted for any staff member who has patient contact or handles sterile supplies.

Bloodborne pathogen exposures (needlestick or other exposure) The prompt treatment of injuries and exposures is vital to prevent the transmission of disease. Whatever the exposure, IMMEDIATE cleaning of the exposure site is the first priority. • Skin wounds should be cleaned with soap and water • Mucous membranes should be flushed thoroughly with water • Eyes should be irrigated with a liter of normal saline After cleaning the exposure site, call 5-STIX (5-7849) and follow instructions to contact the ID physician. Workplace injuries should be reported immediately on the “Employee Report of Incident Form” and to the Occupational Injury Clinic (Blalock 139, Monday–Friday, 7:30 a.m. to 4 p.m., 5-6433), and to your supervisor.

Standard Precautions a c

All employees must follow Standard Precautions for all patients as e r follows: p l o r t

• Routine hand hygiene • Bag contaminated linen at point of use n o

• Consistent and correct glove use • Regular cleaning of environmental c n

surfaces o i • Appropriate use of gowns to prevent • Routine cleaning or disposal of t c e

contamination of uniform/clothing patient-care equipment f n • Appropriate use of masks, eye • Strict adherence to I 2

protection and face shields (i.e., when occupational safety requirements . suctioning, or when splash likely) 8

Disease-specific infection control n o i t

recommendations a d n e

Creutzfeldt-Jakob disease (CJD) m m

CJD, variant CJD and other diseases caused by prions are resistant to a o c number of standard sterilization and disinfection procedures. Iatrogenic e r l

transmission of CJD has been associated with percutaneous exposure to o r t

medical instruments contaminated with prion/central nervous system n o

(CNS) tissue residues, transplantation of CNS and corneal tissues and c n

recipients of human growth hormone and gonadotropin. Transmission of o i t

CJD has not been associated with environmental contamination or from c e f

person-to-person via skin contact. The following additional precautions n i c must be made when processing equipment that could be contaminated i f i with prion related material: c e

• Notify HEIC and the unit manager/charge nurse immediately of any p s -

suspected or confirmed CJD case and refer to the CJD policy on the e s a

HEIC Web site. e s • Use disposable equipment whenever possible. If non-disposable i D 3

equipment is used, Central Sterile Department shall be notified prior to . the start of the procedure. 8 • Label all laboratory and pathology requisitions as suspected CJD and notify the lab before sending specimens. • The following are considered highly infective and should be handled with extreme caution: brain, spinal cord, optic tissues and pituitary gland • The following are considered to be of lower infectivity: CSF, kidney, liver, lung, lymph nodes, spleen, placenta, tonsillar tissue and olfactory tissue.

Methicillin-resistant Staphylococcus aureus (MRSA) Routine active surveillance cultures for MRSA are performed on select units to identify patients with MRSA. Surveillance culture results are found in the electronic patient record with the test name “MRSA Surv. Cult.” When a culture is positive for MRSA the patient is placed on Contact Precautions. The results are to be used for isolation purposes, not to guide therapy or clinical care. The overwhelming majority of positive surveillance cultures represents colonization, not infection, and should not prompt any antimicrobial therapy. Surveillance cultures should be obtained upon admission and weekly in the following units: MICU, WICU, CVSICU, SICU, CTU (9W), NCCU, CCU/PCCU, PICU, NICU, oncology units, Osler 8. A swab of the anterior nares should be obtained and sent for culture.

The patient must be off antibiotics for ≥ 48 hours and cultures from n i c original site of infection AND 3 stool or perirectal cultures taken ≥ 1 i f i week apart must be negative. Once this is accomplished, call HEIC to c e review culture data and initiate deflagging. p s - e s

Varicella-Zoster a e s Immunocompetent patients with disseminated zoster and all i immunosuppressed patients with zoster need Contact AND Airborne D 3 .

Precautions. The following definitions apply to patients with zoster: 8 • Immunosuppressed: bone marrow transplant within the past year; acute leukemia; solid organ transplant recipients; patients receiving cytotoxic or immunosuppressive treatments, including steroid treatment for ≥ 30 days with the following doses: dexamethasone 3 mg daily, cortisone 100 mg daily, hydrocortisone 80 mg daily, prednisone 20 mg daily, methylprednisone 16 mg daily; HIV+ patients with CD4 < 200 • Disseminated: lesions outside of 2 contiguous dermatomes

Central vascular access device (VAD) recommendations All healthcare workers who place central lines are required to take the online VAD training (see HEIC Web site). To prevent central VAD-related infections follow the central line bundle and use the central line checklist: Insertion • Clean hands thoroughly • ChloraPrep® for patient skin antisepsis and allow to dry completely • Subclavian is the preferred site for central line insertion • Use full barrier precautions (drape patient from head to toe and rail to rail) and aseptic technique • Lines placed emergently should be changed as soon as the patient is medically stable Care • Scrub the hub ten times with alcohol

137 s • Change a semipermeable transparent central line dressing every 7 n o i

t days, unless it is damp, loose or soiled, in which case change the a d dressing immediately. Change gauze dressing every 48 hours n e • Change peripheral IV site and tubing every 96 hours m • Remove line as soon as possible m o

c • Refer to the VAD policy on the HEIC Web site for more details. e r l o r Evidenced-based recommendations for prevention of surgical t n

o site infections (SSI) c n Pre-operative interventions o i t • Identify and treat remote site infections c e f • Postpone elective procedures until remote infection is resolved n i

c • Control glucose pre- and post-operatively i f i • Encourage the patient to stop smoking at least 30 days pre-operatively c e

p • Instruct patient to wash with 4% chlorhexidine gluconate (CHG or s

- ®

e Hibiclens ) the night before and the morning of surgery. (Directions s a can be found at www.hopkinsmedicine.org/heic) e s i • Use appropriate peri-operative antibiotic prophylaxis (see p. 112) that D

3 is given prior to, but no more than 1 hour before, skin incision . 8 Intra-operative interventions • Clean hands with surgical scrub sponge 2–5 minutes and pick nails. For subsequent cases Avagard ® can be used • Do not remove hair at incision unless necessary for the operation • Never shave, only use clippers • Hair removal, if necessary, should take place immediately before surgery • Prepare the surgical site and surrounding area with an approved antiseptic and allow to DRY prior to placing drapes • Maintain normal core temperature (36.5°C) throughout the procedure • Control serum blood glucose levels using insulin as necessary • Use aseptic technique when placing IV devices • Use aseptic technique when manipulating stopcocks and ports • Assemble sterile equipment and solutions immediately before use • Administer 80% O2 when possible Post-operative interventions • Place a sterile dressing (as anatomically possible) 24–48 hours post surgery • Change dressing using sterile supplies and good hand hygiene • Control serum blood glucose levels using insulin as necessary

IBW female (kg) = (2.3 x inches over 5') + 45.5 d e

IBW male (kg) = (2.3 x inches over 5') + 50 d i s o

For patients < 20% over IBW, use Actual Body Weight (ABW) c y l g

Estimation of creatinine clearance (CrCl) by Cockcroft-Gault . A equation: (If a patient’s renal function is declining, this equation may overestimate CrCl)

CrCl = (140 – age) (weight in kg*) x 0.85 (if female) 72 (serum creatinine) * Use Actual Body Weight (ABW) unless patient ≥ 20% over IBW, use DBW as described above Extended-interval dosing, also sometimes referred to as “once- daily” administration, utilizes higher dose and less frequent aminoglycoside administration, whereas patient-specific dosing, previous referred to as “traditional dosing”, typically utilizes smaller doses with more frequent administration. See table below for dosing recommendation based on indication and patient’s renal function. For mycobacterial infections, urinary tract infections, SICU/WICU protocol and gram-positive synergy (e.g. endocarditis), please see separate sections below.

Aminoglycoside dosing in mycobacterial i r o t

infections i n o m

Amikacin is the preferred agent to treat all mycobacterial infections, d except Mycobacterium chelonae. For M. chelonae infections, Tobramycin n a

is the recommended aminoglycoside. Streptomycin is another g n i

aminoglycoside sometimes used to treat mycobacterial infections such s o

as M. tuberculosis. Please contact the Antimicrobial Stewardship d

Program pharmacist for Tobramycin/Streptomycin dosing e d i recommendation for this indication. s o c y Amikacin: l g

Normal renal function: o n i

Once daily: 15 mg/kg IV Q24H (or 10 mg/kg IV Q24H if >50 years of m A

age) . Thrice weekly: 25 mg/kg IV three times a week (may be more difficult to A tolerate) Abnormal renal function: Discuss with pharmacy clinical specialist Therapeutic drug monitoring: Peak and trough not generally necessary, except in those with renal insufficiency (GFR <60 mL/min) and if SCr increases by 0.5 mg/dL or >30% from baseline while patient on aminoglycoside therapy. Check a trough concentration to monitor for toxicity. Peaks in the low 20 mcg/mL range are acceptable, and trough concentrations are preferably <4 mc/mL or undetectable.

Aminoglycoside dosing in urinary tract infections

CrCl (mL/min) Gentamicin/Tobramycin Amikacin ≥60 3 mg/kg IV Q24H or 10 mg/kg IV Q24H or 1 mg/kg IV Q8H 3 mg/kg IV Q8H 40-59 1 mg/kg Q12H 3 mg/kg IV Q12H 20-39 1 mg/kg Q24H 3 mg/kg IV Q24H <20 1 mg/kg ONCE* 3 mg/kg IV ONCE* *Give one dose, check level in 24 hours, redose when Gentamicin/Tobramycin level <1 mcg/mL or Amikacin <4 mcg/mL Aminoglycosides are highly concentrated in urine; therefore, therapeutic drug monitoring is not necessary in patients with normal renal function. Suggested doses in the above table will likely provide adequate urine concentrations for highly susceptible organisms. Trough should be checked to monitor for toxicity in patients with renal insufficiency (GFR <60 mL/min) and if SCr increases by 0.5 mg/dL or >30% from baseline while patient on aminoglycoside therapy. • Gentamicin/Tobramycin: desired trough <1 mcg/mL or undetectable. • Amikacin: desired trough <4 mcg/mL or undetectable. 143 A.

• Consider biweekly clinical screening for ototoxicity s o

• Check baseline visual acuity using a Snellen pocket card c y l

• To screen for ototoxicity, have patient shake head and then re-read g o n card. i m

• Concern should be raised if patient loses 2 lines of visual acuity. A

†For patients with CrCl <15 mL/min and not receiving hemodialysis redose when random level <15–20 mcg/mL. For patients receiving maintenance hemodialysis, redose after hemodialysis session if pre-hemodialysis level <25 mcg/mL for pneumonia, osteomyelitis, endocarditis or bacteremia. For meningitis, consider redosing patient if pre-hemodialysis level <30 mcg/mL. Loading dose should not be used in these patients.

THERAPEUTIC DRUG MONITORING (LEVELS) • Peak levels should NOT be obtained. • Trough levels are the most accurate and practical method for monitoring Vancomycin effectiveness and toxicity.

146 Measuring serum Vancomycin levels g n i • Trough levels should be obtained just prior to the next dose at steady- r o t i

state conditions (approximately before the 4th dose). n • In patients with ESRD on hemodialysis, it is preferable to obtain a pre- o m

hemodialysis level with the routine laboratory venipuncture on the d n a

morning of hemodialysis. In the event a pre-hemodialysis level is not g n

obtained, a post-hemodialysis level may be drawn at least six hours i s

after the dialysis session. o d

n

• Trough levels should be considered in patients with any the following i c

circumstances: y m

• Receiving aggressive dosing (>1500 mg Q12H) or Q8H interval o c

• Serious infections such as meningitis, endocarditis, osteomyelitis, n a V

and MRSA pneumonia. .

• Unstable renal function (change in SCr of 0.5 mg/dL or 50% from B baseline) or dialysis • Concurrent therapy with nephrotoxic agents (e.g. aminoglycosides, Colistin, Amphotericin B) • Prolonged courses (>3-5 days) of therapy. • Frequency of monitoring Vancomycin trough levels: • Once-weekly monitoring is recommended for patients with stable renal function who have achieved desired trough levels. • More frequent monitoring is recommended for patients who are hemodynamically unstable and/or with changing renal function. Desired Vancomycin trough levels • Pneumonia, osteomyelitis, endocarditis, bacteremia: 15-20 mcg/mL • CNS infections: 20 mcg/mL • Neutropenic fever, skin and skin-structure infections: 10-15 mcg/mL • For MRSA infections serum trough concentrations >10 mcg/mL should always be maintained to avoid development of resistance. Monitoring for Toxicity • Serum creatinine should be measured at least every other day initially, then weekly if patient’s renal function remains stable. • Limited data suggest a direct causal relationship between nephrotoxicity and higher serum trough concentrations (>15-20 mcg/mL). Monitor Vancomycin trough levels (see above for frequency and indications). • Formal audiology testing is not recommended for patients receiving Vancomycin, unless signs and symptoms of ototoxicity became apparent.

When using an agent that is considered to be bioequivalent (no o r c significant difference in rate and extent of absorption of the therapeutic i m i

ingredient) via the parenteral and oral route, the oral formulation is t n

preferred if the patient does not have the contraindications listed below. a
