Optimizing Use of COVID-19 Personal Protective Equipment among Resident Physicians at a Veterans Affairs Hospital

ABSTRACT

Background. Correct personal protective equipment (PPE) use is key to prevent infection. Observations on a single unit at the Veterans Affairs (VA) Tennessee Valley Healthcare System (TVHS) prior to COVID-19 (October 2019-February 2020) showed low rates of correct PPE use among healthcare workers (HCWs) (Figure 1). In response to the COVID-19 epidemic, the VA implemented new PPE protocols. Based on our initial observations, we were concerned that incorrect use of PPE may increase the risk of COVID-19 exposure among HCWs. Resident physicians, who work at many sites, may be at high-risk for incorrect PPE use due to rapid turnover and limited site-specific PPE training. We aimed to assess and improve COVID-19 PPE use among internal medicine residents rotating at the VA TVHS. Figure 1 Pre-COVID-19 Observations of Adherence to Contact Precaution Protocols at the Veterans Affairs Tennessee Valley Healthcare System Methods. We used the plan, do, study, act (PDSA) model. Prior to starting VA rotations, residents were emailed PPE education to review. We implemented a 1-hour video conference PPE protocol review at rotation start followed by in-person PPE use evaluations for residents performed by infectious diseases fellows on day 2 and day 5-6 post-review to provide just-in-time educational intervention. Errors at each PPE don/ doff step were tracked. Correct PPE use data from both observations were compared using McNemar's test. Baseline and post-implementation resident surveys assessed PPE use knowledge and comfort. Results. Pre-implementation survey response rate was 72% (21/29);19/21(91%) reported knowing which PPE to use and 16/21(76%) reported knowing how to safely don/doff PPE. Twenty of 29 (69%) residents completed both observations. Errors decreased by 55% (p=0.0045) from 17/20 (85%) to 6/20 (30%) between initial and follow up observations. Errors in hand hygiene, inclusion of all donning/doffing steps, and PPE reuse decreased, but PPE don/doff order errors increased (Figure 2). Postproject survey response rate was 16/29 (55%). All 16 reported knowing which PPE to use and how to safely don/doff PPE, and 11/16 (69%) residents felt both online and in-person interventions were helpful. Figure 2 COVID-19 PPE Errors and Correction Types by Observation Conclusion. Correct COVID-19 PPE use is essential to protect HCWs and patients. Just-in-time education intervention for PPE training may yield higher correct use compared to pre-recorded or online training.
