Tuberculosis in Healthcare Workers

This study investigates the factors affecting the implementation of active tuberculosis (TB) surveillance in rural and urban districts of the Eastern Cape, South Africa, from the perspective of healthcare workers. Utilizing a cross-sectional survey method, data was gathered via an electronic questionnaire through REDCap software. The approach effectively captures healthcare workers' views on systemic and contextual challenges at a specific time, though self-reported data may introduce bias, and the focus solely on healthcare workers might overlook patient and community stakeholder insights.[1]

Variables in this study include independent variables such as geographical settings (rural vs. urban districts) and healthcare worker demographics and roles. Dependent variables involve factors impacting TB surveillance like training, transportation, coordination, and community acceptance. Confounding factors include socioeconomic disparities and variations in clinic resources, while control variables were demographic comparatives of the survey participants. Key results indicated significant challenges like CHW transport issues and community distrust, alongside a substantial discrepancy in resource allocation between rural and urban settings. The study concludes that multiple barriers, including leadership and resource deficiencies, affect TB surveillance, necessitating tailored interventions for different locales.[1]

In Taiwan, Tuberculosis (TB) poses a significant occupational risk for healthcare workers (HCWs), who exhibit a higher incidence of active TB compared to the general population when adjusted for age, sex, and diagnosis year. Notably, the outcomes of TB in HCWs are more favorable than those of non-HCW patients treated in the same settings, primarily due to factors such as the healthy worker effect, expedited diagnosis, and reduced treatment delays, all contributing to lower TB mortality rates among healthcare workers.[2]
