RESUMEN
@#<p style="text-align: justify;"><strong>BACKGROUND:</strong> Nosocomial TB transmission adversely affects inpatients and healthcare workers (HCWs). HCWs have a higher risk of tuberculosis and MDR-TB compared to the general population. Nosocomial TB outbreaks have occurred among patients with HIV/AIDS. Hospitals need to examine TB infection control measures in order to address this growing concern.</p><p style="text-align: justify;"><strong>OBJECTIVE:</strong> This study aimed to evaluate the TB infection control strategies in the adult service wards of the Philippine General Hospital (PGH).</p><p style="text-align: justify;"><strong>METHODS:</strong> This descriptive study was conducted on adult inpatients with bacteriologically-confirmed PTB admitted in April-August 2016. A data collection tool based on Center for Disease Control (CDC) guidelines was utilized for chart review. Baseline characteristics, diagnosis, treatment, and isolation intervals were obtained and compared between areas. In-hospital TB infection control practices were reviewed using the CDC TB Risk Assessment Worksheet with data from the TB-DOTS, UP Health Service, PGH Hospital Infection Control Unit, and PGH Department of Laboratories.</p><p style="text-align: justify;"><strong>RESULTS:</strong> Of the 95 patients with bacteriologically-confirmed PTB, data from 72 medical records were available and included in the analysis. Majority were Medicine patients (55.6%) with a diagnosis of pneumonia (52.8%). Only 61.1% were PTB suspects on admission. The mean diagnosis interval was 5.82 days±5.473, the mean treatment interval was 0.77 days±2.941, and the mean isolation interval was 8.23 days±6.372. Only 41.7% were successfully isolated. The most common reasons for isolation failure/delay were lack of vacancy (ER, Medicine wards) and lack of isolation room (Surgical wards). Treatment initiation rate was 66.7% while TB-DOTS inpatient referral rate was 55.6%. The hospital is classified as having potential ongoing transmission of PTB.</p><p style="text-align: justify;"><strong>CONCLUSION:</strong> In this study, TB treatment was promptly started but there were delays in diagnosis and isolation. Gaps included 1) lack of recognition of a PTB case, 2) limited isolation rooms, and 3) inadequate utilization of TB-DOTS. TB infection control measures need to be strengthened in order to prevent nosocomial transmission of PTB.</p>
