  • Antimicrobial Surgical Prophylaxis
    Antimicrobial Surgical Prophylaxis The antimicrobial surgical prophylaxis protocol establishes evidence-based standards for surgical prophylaxis at The Nebraska Medical Center. The protocol was adapted from the recently published consensus guidelines from the American Society of Health-System Pharmacists (ASHP), Society for Healthcare Epidemiology of America (SHEA), Infectious Disease Society of America (IDSA), and the Surgical Infection Society (SIS) and customized to Nebraska Medicine with the input of the Antimicrobial Stewardship Program in concert with the various surgical groups at the institution. The protocol established here-in will be implemented via standard order sets utilized within One Chart. Routine surgical prophylaxis and current and future surgical order sets are expected to conform to this guidance. Antimicrobial Surgical Prophylaxis Initiation Optimal timing: Within 60 minutes before surgical incision o Exceptions: Fluoroquinolones and vancomycin (within 120 minutes before surgical incision) Successful prophylaxis necessitates that the antimicrobial agent achieve serum and tissue concentrations above the MIC for probable organisms associated with the specific procedure type at the time of incision as well as for the duration of the procedure. Renal Dose Adjustment Guidance The following table can be utilized to determine if adjustments are needed to antimicrobial surgical prophylaxis for both pre-op and post-op dosing.

S. M. Dr. S. Habeeb Mohammed Dr. Shameem Banu Associate Professor- Microbiology Associate Professor-Surgery Professor and HOD- Microbiology Chettinad Hospital & Research Chettinad Hospital & Research Chettinad Hospital & Research Insitute Insitute Insitute Dr. Jayanthi S. Associate Professor- Microbiology Chettinad Hospital & Research Insitute ABSTRACT Methicillin resistant Staphylococcus aureus (MRSA), commonest cause of acute bacterial skin and skin structure infection (ABSSSI) has only limited treatment options like vancomycin, Linezolid and teicoplanin. Staphylococcus aureus with reduced susceptibilities to vancomycin is developing nowadays among nosocomial infec- tion. A newest cephalosporin – Ceftaroline has received FDA approval for the treatment of ABSSSI recently has unique activity against MRSA. The aim of the study is to know the prevalence of Staphylococcus aureus in ABSSSI patients and to evaluate the in vitro activity of Ceftaroline, in comparison with other drugs. Minimum Inhibitory Concentration for vancomycin and Ceftaroline were determined by E-test strips. Out of 235 Staphylococcus aureus isolated from ABSSSI patient 32% were MRSA. No vancomycin resistant strain isolated in our study. In vitro, Ceftaroline control the growth of MRSA very effectively at 2mg/ml itself. Ceftaroline is a most welcomed drug in the treatment of MRSA. INTRODUCTION: MATERIALS AND METHODS: Complicated skin and skin structure infection (CSSSIs), now This study was carried out in Chettinad health city and known by the new US FDA as Acute bacterial skin and skin Research Institute, a tertiary care center hospital (Chen- structure infections (ABSSSI) are the most common infec- nai) between April 2013 and May 2014.

    TML\MSH Microbiology Department Policy # MI\ANTI\04\03\v03 Page 1 of 5 Policy & Procedure Manual Section: Antimicrobial Susceptibility Testing Subject Title: Appendix III - Double Disk Manual Test for ESBL Issued by: LABORATORY MANAGER Original Date: January 10, 2000 Approved by: Laboratory Director Revision Date: November 21, 2005 APPENDIX III - DOUBLE DISK TEST FOR ESBL I. Introduction Class A or Bush Group 1 extended spectrum beta-lactamases (ESBLs) are inhibited by clavulanic acid. This may be detected by testing the suspected organism to a 3rd generation cephalosporin alone and in combination with clavulanic acid. If the combination results in an expanded zone of inhibition compared to that of the 3rd generation cephalosporin alone, it is indicative of the presence of an ESBL. II. Materials Mueller-Hinton (MH) agar (150) mm 20/10 mg amoxicillin-clavulanate disc 30 mg ceftazidime disc 30 mg ceftriaxone or cefotaxime disc 30 mg aztreonam disc 10 mg cefpodoxime disc (optional) 30 mg cefoxitin disc Quality control strain: E. coli ATCC 51446 III. Procedure 1. Prepare a bacterial suspension of the organism to be tested that has a turbidity equivalent to that of a 0.5 McFarland standard. 2. Inoculate a Mueller-Hinton agar plate with this suspension in accordance with NCCLS M100-S10 (M2) guidelines for disc diffusion testing. 3. Place the amoxicillin-clavulanic acid disc towards the centre of the plate. 4. Carefully measure 15 mm out from the edge of that disc at 90o angles marking the plate. 5. Place a ceftazidime disk on the plate so that its inner edge is 15 mm (the mark) from the amoxicillin-clavulanic acid disc (See Figure 1 KB-ESBL Template).

  • Ampicillin/Sulbactam Vs. Cefoxitin for the Treatment of Pelvic Inflammatory Disease
    Infectious Diseases in Obstetrics and Gynecology 5:319–325 (1997) © 1998 Wiley-Liss, Inc. Ampicillin/Sulbactam Vs. Cefoxitin for the Treatment of Pelvic Inflammatory Disease Joseph G. Jemsek* and Frank Harrison Department of Obstetrics and Gynecology, Charlotte Memorial Hospital, Charlotte, NC ABSTRACT Objective: The safety and efficacy of ampicillin plus sulbactam were compared with those of ce- foxitin in the treatment of women with pelvic inflammatory disease (PID). Methods: This single-site, randomized, prospective, third-party-blinded, comparative, parallel- treatment study enrolled 93 women with a diagnosis of PID. Patients were treated with either ampicillin/sulbactam (2 g/1 g, administered intravenously [IV], every 6 h) or cefoxitin (2 g, admin- istered IV, every 6 h) for a minimum of 12 doses. Patients with cultures positive for Chlamydia trachomatis also received concurrent oral or IV doxycycline (100 mg twice daily). Patients with cultures negative for C. trachomatis received prophylactic oral doxycycline (100 mg twice daily) for 10–14 days after treatment with either ampicillin/sulbactam or cefoxitin was completed. Results: Ninety-three patients were entered in the study: 47 in the ampicillin/sulbactam arm and 46 in the cefoxitin arm. All 93 patients were evaluable for safety; 61 (66%) were evaluable for efficacy. Demographic characteristics were similar for the groups. Of the 27 evaluable ampicillin/ sulbactam-treated patients, 67% experienced clinical cure, 30% improved, and 4% failed treatment. Respective values for the 34 cefoxitin-treated patients were 68%, 24%, and 9% (P = 0.67). Patho- gens were eradicated in 70% of the women given ampicillin/sulbactam vs. 56% of those who re- ceived cefoxitin (P = 0.64).

  • Staphylococcus Aureus Bloodstream Infection Treatment Guideline
    Staphylococcus aureus Bloodstream Infection Treatment Guideline Purpose: To provide a framework for the evaluation and management patients with Methicillin- Susceptible (MSSA) and Methicillin-Resistant Staphylococcus aureus (MRSA) bloodstream infections (BSI). The recommendations below are guidelines for care and are not meant to replace clinical judgment. The initial page includes a brief version of the guidance followed by a more detailed discussion of the recommendations with supporting evidence. Also included is an algorithm describing management of patients with blood cultures positive for gram-positive cocci. Brief Key Points: 1. Don’t ignore it – Staphylococcus aureus isolated from a blood culture is never a contaminant. All patients with S. aureus in their blood should be treated with appropriate antibiotics and evaluated for a source of infection. 2. Control the source a. Removing infected catheters and prosthetic devices – Retention of infected central venous catheters and prosthetic devices in the setting of S. aureus bacteremia (SAB) has been associated with prolonged bacteremia, treatment failure and death. These should be removed if medically possible. i. Retention of prosthetic material is associated with an increased likelihood of SAB relapse and removal should be considered even if not clearly infected b. Evaluate for metastatic infections (endocarditis, osteomyelitis, abscesses, etc.) – Metastatic infections and endocarditis are quite common in SAB (11-31% patients with SAB have endocarditis). i. All patients should have a thorough history taken and exam performed with any new complaint evaluated for possible metastatic infection. ii. Echocardiograms should be strongly considered for all patients with SAB iii. All patients with a prosthetic valve, pacemaker/ICD present, or persistent bacteremia (follow up blood cultures positive) should undergo a transesophageal echocardiogram 3.
