title: [A survey on nosocomial tuberculosis infection control in hospitals in Osaka City].
abstract: OBJECTIVE
  To ascertain nosocomial tuberculosis (TB) infection control practice in hospitals in Osaka City.
  
  
  METHODS
  A questionnaire was distributed in the orientation meeting and collected at the occasion of medical inspection in all 196 hospitals in Osaka City in 2003.
  
  
  RESULTS
  TB patients were diagnosed in about half of hospitals in the past 3 years. Basic TB infection control measures were taken in the majority of hospitals; such as chest X-ray screening for all inpatients, health check for employees, tuberculin skin test (TST) for newly employed staff, and nomination of a person in charge of TB infection control. Control measures were practiced more often in hospitals where TB patients were diagnosed, such as "fiberoptic bronchoscopy is to be conducted last in the working hours to avoid contamination of TB bacilli in a room," "TST (including two-step method) for all newly employed staff," "Staff wear N95 mask when they deal with TB patients/suspects," and the differences were statistically significant.
  
  
  CONCLUSIONS
  It is necessary in hospitals in Osaka City to strengthen nosocomial TB infection control as TB patients were diagnosed in about half of hospitals in the past 3 years. Low cost infection control measures were undertaken more often among hospitals where TB patients were diagnosed. Introduction of high cost equipment or improvement of facilities should be considered in hospitals of high TB risk. Guidelines formulated based on analysis of the survey should facilitate all hospitals to introduce at least low cost effective tuberculosis infection control measures.
