Introduction and aims:The COVID-19 pandemic poses an ongoing risk to health workers globally. This is particularly true in low- and middle-income countries (LMICs) where resource constraints, ongoing waves of infection, and limited access to vaccines disproportionately burden health systems. Thus, infection prevention and control (IPC) training for COVID-19 remains an important tool to safeguard health workers. We report on the implementation of evidence-based and role-specific COVID-19 IPC training for health workers in a hospital and public health field setting in Sri Lanka.Methods:We describe the development of training materials, which were contextualized to local needs and targeted to different staffing categories including support staff. We describe development of role- and context-specific IPC guidelines and accompanying training materials and videos during the first year of the COVID-19 pandemic. We describe in-person training activities and an overview of session leadership and participation.Results:Key to program implementation was the role of champions in facilitating the training, as well as delivery of training sessions featuring multi-media videos and role play to enhance the training experience. A total of 296 health workers participated in the training program sessions. Of these, 198 were hospital staff and 98 were from the public health workforce. Of the 296 health workers who participated in a training session, 277 completed a pre-test questionnaire and 256 completed post-test questionnaires. A significant increase in knowledge score was observed among all categories of staff who participated in training;however, support staff had the lowest pre-test knowledge on IPC practices at 71%, which improved to only 77% after the formal class.Conclusion:Implementing an IPC training program during a complex health emergency is a challenging, yet necessary task. Leveraging champions, offering training through multiple modalities including the use of videos and role play, as well as inclusion of all staff categories, is crucial to making training accessible.
