Training health workers at scale in Nigeria to fight COVID-19 using the InStrat COVID-19 tutorial app: an e-health interventional study

Abstract

Background: Health worker training is an essential component of epidemic control; rapid delivery of such training is possible in low-middle income countries with digital platforms. Methods: Based on prior experience with the Ebola outbreak, we developed and deployed a bespoke InStrat COVID-19 tutorial app, to deliver accurate and regularly updated information about COVID-19 to frontline health workers and epidemic response officers across 25 states of Nigeria. The potential effectiveness of this app in training frontline health workers was assessed through online pre- and post-tests and a survey. Results: A total of 1051 health workers from 25 states across Nigeria undertook the e-learning on the InStrat COVID-19 training app. Of these, 627 (57%) completed both the pre- and post-tests in addition to completing the training modules. Overall, there were statistically significant differences between pre- and post-tests knowledge scores (54 increasing to 74). There were also differences in the subcategories of sex, region and cadre. There were higher post-test scores in males compared with females, younger versus older and southern compared with northern Nigeria. A total of 65 (50%) of the participants reported that the app increased their understanding of COVID-19, while 69 (53%) stated that they had applied the knowledge and skills learnt at work. Overall, the functionality and usability of the app were satisfactory. Conclusion: Capacity building for epidemic control using e-health applications is potentially effective, can be delivered at minimal cost and service disruption and can serve as a tool for capacity building in similar contexts.
