Abstract: Objectives Literature states a higher self‐contamination rate among healthcare workers (HCWs) while doffing personal protective equipment (PPE). During the Covid‐19 pandemic, onsite trained observers were not always available to monitor PPE compliance. The remote audio‐visual doffing surveillance (RADS) system has the potential to overcome this limitation. We aimed to compare the efficacy of this real‐time RADS system against the onsite buddy system for monitoring the doffing of PPE. Methods This prospective, observational study was carried out at our tertiary care centre in northern India. 200 HCWs who cared for Covid‐19 patients in the intensive care units/operation theatres were included. Group A included HCWs who performed doffing with the help of an onsite trained observer and group B included HCWs who performed doffing with the RADS system. An independent observer noted the error at any step using the CDC doffing checklist, in both groups. An online questionnaire to analyse the level of satisfaction post‐doffing was also surveyed. Results The proportion of errors committed during doffing was significantly lower in group B compared to group A with a low relative risk of 0.34 (95% CI 0.22–0.51) (p
