摘要

Objectives Tuberculosis (TB) infection control measures are very important to prevent nosocomial transmission and protect healthcare workers (HCWs) in hospitals. The TB infection control situation in TB treatment institutions in southeastern China has not been studied previously. Therefore, the aim of this study was to investigate the implementation of TB infection control measures in TB-designated hospitals in Zhejiang Province, China. Design Cross-sectional survey using observation and interviews. Setting All TB-designated hospitals (n=88) in Zhejiang Province, China in 2014. Primary and secondary outcome measures Managerial, administrative, environmental and personal infection control measures were assessed using descriptive analyses and univariate logistic regression analysis. Results The TB-designated hospitals treated a median of 3030 outpatients (IQR 764–7094) and 279 patients with confirmed TB (IQR 154–459) annually, and 160 patients with TB (IQR 79–426) were hospitalised in the TB wards. Most infection control measures were performed by the TB-designated hospitals. Measures including regular monitoring of TB infection control in high-risk areas (49%), shortening the wait times (42%), and providing a separate waiting area for patients with suspected TB (46%) were sometimes neglected. N95 respirators were available in 85 (97%) hospitals, although only 44 (50%) hospitals checked that they fit. Hospitals with more TB staff and higher admission rates of patients with TB were more likely to set a dedicated sputum collection area and to conduct annual respirator fit testing. Conclusions TB infection control measures were generally implemented by the TB-designated hospitals. Measures including separation of suspected patients, regular monitoring of infection control practices, and regular fit testing of respirators should be strengthened. Infection measures for sputum collection and respirator fit testing should be improved in hospitals with lower admission rates of patients with TB.
