Strengthening TB infection control and its impact on TB screening practices among healthcare workers during the COVID-19 Pandemic in Zimbabwe.

Introduction: The risk of exposure to Methods: The strategy, implemented from June 2021-September 2022, included IPC mentorship training, competency assessments, and use of a standardized risk assessment tool for progress monitoring. For the training purposes, the project developed eight practical problem-solving IPC modules including an occupational health component. Trained mentors conducted bi-monthly site support visits (SSV), used a checklist to track compliance, and assessed competencies of HCW at the targeted facilities. Facility-based risk assessments were conducted three times during the project implementation. Results: During the intervention, 1,865 HCW from 105 facilities were trained. Availability and use of personal protective equipment improved by 49% and 42%, respectively. The proportion of HCF with designated areas for sputum collection increased by 43%. The proportion of HCF that screened HCW for TB increased by 42% with 3,761 HCW screened during the project period. Fourteen were diagnosed with TB and referred for care, resulting in 372 new cases per 100,000. Conclusion: The implemented strategy of training, mentorship, and regular SSV strengthened TBIC measures, improved TB screening practices and case finding among HCW. Improving and maintaining practices is critical for effective TBIC.
