    Guidelines for Prevention of Healthcare Associated Lower

    State of Kuwait Ministry of Health Infection Control Directorate Guidelines for Prevention of Healt Care Associated LRTI Aug. 2006 1 I- Introduction Respiratory tract infections are extremely common health-care associated infections. Lower respiratory tract infection incorporates a spectrum of disease from acute bronchitis to pneumonia. Several factors (age, underlying disease, environment) influence mortality, morbidity and also microbial aetiology especially with the most frequently identified antibiotic resistance of respiratory pathogens. Of the lower respiratory tract infections, pneumonia remains the most common infection seen among hospitalized patients. It is defined as a lower respiratory tract infection occurring > 48 hrs of admission to a hospital or nursing home in a patient who was not incubating the infection on admission. It is the second most common health-care associated infection worldwide after urinary tract infection accounting for 13-18% of all health-care associated infections. Health-care associated pneumonia tends to be more serious because defense mechanisms against infection are often impaired , and the kind of infecting organisms are more dangerous than those generally encountered in the community. It is commonly caused by pathogens that need aggressive diagnostic approach with prompt recognition and urgent treatment to reduce morbidity and mortality; often the strains causing health-care associated pneumonia are multiple. It is complicate up to 1% of all hospitalizations. Critically ill patients who require mechanical ventilation are especially vulnerable to develop ventilator associated pneumonia (VAP). Because of its tremendous risk in the last two decades, most of the research on hospital associated pneumonia has been focused on VAP. As treatment, prognosis and outcome of VAP may differ significantly from other forms of hospital acquired pneumonia, it will be discussed extensively.

Department of Internal Medicine, School of Medicine, Kyungpook National University, 680 Gukchaebosang-ro, Jung-gu, 700-842, Daegu, Republic of Korea. Email: [email protected]. Abstract: Pseudomembranous tracheitis (PMT) is a rare condition characterized by pseudomembrane formation in the tracheobronchial tree that may be associated with infectious and noninfectious processes. However, PMT attributed to Mycoplasma pneumoniae (M. pneumoniae), a common atypical respiratory infectious pathogen, has not been reported till date. Here, we report about a 29-year-old woman with complaints of severe persistent cough and radiographic deterioration despite antibiotics administration for pneumonia at an outside facility. She was finally diagnosed as having PMT with bilateral diffuse bronchiolitis caused by M. pneumoniae infection. The diagnosis was made based on a bronchoscopic finding of a pseudomembrane that partially covered the membranous portion of the upper and middle trachea, a positive polymerase chain reaction (PCR) test with bronchial aspirate, and a positive serological test for M. pneumoniae without detection of any other causative pathogen through an extensive workup. Her symptoms and radiographic findings improved in response to moxifloxacin and corticosteroid treatment. This case is a rare presentation of M. pneumoniae infection complicating PMT in a young adult without any known risk factors.

While they are generally considered safe, they can be associated with numerous short and long-term complications, many of which can occur long after their placement and cause significant morbidity. Performers of these procedures should possess a comprehensive understanding of procedural indications and contraindications, and know how to recognize and manage complications that may arise. In this review, we highlight complications of percutaneous tracheostomy and describe strategies for their prevention and management, with a special focus on post-tracheostomy
