Vax the Max, a Gamification Intervention for COVID-19 Vaccination Task Engagement in the Inpatient Setting

Abstract

The development of vaccines for SARS-CoV-2 has offered game-changing protection from severe disease and death from COVID-19. Despite efforts to vaccinate individuals in the ambulatory setting, a sizable minority of the US population remains unvaccinated for COVID-19. For unvaccinated patients, hospitalization for non-COVID-19 illness offers another opportunity for vaccination. In the summer of 2021, the authors noted that COVID-19 vaccination rate for medicine inpatients at their hospital had fallen to 5.3 vaccine doses administered per 4-week block. In response, they created Vax the Max, a gamification program of COVID-19 vaccination tasks where internal medicine resident teams were awarded points for completing these tasks. Residents were anonymously surveyed after participation. The hospital demonstrated higher rates of administering the initial COVID-19 vaccine dose and completing the vaccine series in the inpatient setting per 4-week plan-do-study-act cycle after implementation of Vax the Max (5.3 versus 8.8 doses per plan-do-study-act cycle). Among residents, 76.8% reported that Vax the Max spurred their COVID-19 task engagement, and 66% reported that a similar gamification model could be utilized for a different clinical task in the future. An increase was observed in the COVID-19 vaccination rate for medicine inpatients after launching the Vax the Max competition. This occurred in the setting of resident turnover every 4 weeks, which normally makes practice sustainment more challenging. Despite this, a high degree of engagement was produced by itinerant residents. There is potential to explore similar gamification approaches involving resident physicians in areas of quality improvement and patient safety.
