Tuberculosis Infection Control in MDR-TB designated hospitals, Jiangsu Province of China

Abstract

Background Hospital-acquired TB (Tuberculosis) infection among healthcare workers (HCWs) and patients is a severe problem due to the increased attributable risk of TB infection among these groups. Methods A standardized tool was applied. The assessment was conducted by direct observation, document review, and interviews with the facility heads. Baseline evaluation of TBIC (Tuberculosis infection control) in TB outpatient , inpatient departments, and laboratories was completed by January 2019. Based on the results, we implemented a comprehensive package of interventions, including administrative, environmental engineering, and respiratory protection (PPE) three-level hierarchy of controls. Subsequent monitoring was finalized quarterly and improvement measures should be formulated accordingly. More than two years of follow-up data was collected until August 31, 2021, by hospitals, municipality CDCs, and Jiangsu provincial CDC. Results At baseline, the implementation rate of administrative, environmental engineering and PPE IC was 57.29%, 59.21%, and 66.63%, respectively. After evaluation and implementation, priority way for cough patients was established, mechanical ventilation and the use of masks were improved, UV and UVGI lights were settled in need. The implementation rate of administrative, environmental and PPE IC were significantly increased to 86.27%, 87.41%, and 98.42% P<0.05 , respectively. Conclusions After more than one and a half years of intervention, TBIC in the designated hospitals has significantly improved. However, the availability of separate TB wards remains suboptimal. TB IC measures must be strengthened to reduce TB transmission among HCWs and non-TB patients. This method was practical and suitable to be popularized in countries with high TB burden
