Tuberculosis infection control measures and knowledge in primary health centres in Bandung, Indonesia

Health care workers (HCWs) in low- and middle-income countries (LMICs) continue to have an unacceptably high prevalence and incidence of Mycobacterium tuberculosis infection due to high exposure to tuberculosis (TB) cases at health care facilities and often inadequate infection control measures. This can contribute to an increased risk of transmission not only to HCWs themselves but also to patients and the general population.

We assessed implementation of TB infection control measures in primary health centres (PHCs) in Bandung, Indonesia, and TB knowledge among HCWs.

A cross-sectional study was conducted between May and November 2017 amongst a stratified sample of the PHCs, and their HCWs, that manage TB patients in Bandung. Questionnaires were used to assess TB infection control measures plus HCW knowledge. Summary statistics, linear regression and the Kruskal-Wallis test were used for analysis.

The median number of TB infection control measures implemented in 24 PHCs was 21 of 41 assessed. Only one of five management controls was implemented, 15 of 24 administrative controls, three of nine environmental controls and one of three personal respiratory protection controls. PHCs with TB laboratory facilities and high TB case numbers were more likely to implement TB infection control measures than other PHCs (p=0.003). In 398 HCWs, the median number of correct responses for knowledge was 10 (IQR 9-11) out of 11.

HCWs had good TB knowledge. TB infection control measures were generally not implemented and need to be strengthened in PHCs to reduce M. tuberculosis transmission to HCWs, patients and visitors.
