ABSTRACT
BACKGROUND: Healthcare personnel (HCP) may encounter unfamiliar personal protective equipment (PPE) during clinical duties, yet we know little about their doffing strategies in such situations. OBJECTIVE: To better understand how HCP navigate encounters with unfamiliar PPE and the factors that influence their doffing strategies. SETTING: The study was conducted at 2 Midwestern academic hospitals. PARTICIPANTS: The study included 70 HCP: 24 physicians and resident physicians, 31 nurses, 5 medical or nursing students, and 10 other staff. Among them, 20 had special isolation unit training. METHODS: Participants completed 1 of 4 doffing simulation scenarios involving 3 mask designs, 2 gown designs, 2 glove designs, and a full PPE ensemble. Doffing simulations were video-recorded and reviewed with participants during think-aloud interviews. Interviews were audio-recorded and analyzed using thematic analysis. RESULTS: Participants identified familiarity with PPE items and designs as an important factor in doffing. When encountering unfamiliar PPE, participants cited aspects of their routine practices such as designs typically used, donning and doffing frequency, and design cues, and their training as impacting their doffing strategies. Furthermore, they identified nonintuitive design and lack of training as barriers to doffing unfamiliar PPE appropriately. CONCLUSION: PPE designs may not be interchangeable, and their use may not be intuitive. HCP drew on routine practices, experiences with familiar PPE, and training to adapt doffing strategies for unfamiliar PPE. In doing so, HCP sometimes deviated from best practices meant to prevent self-contamination. Hospital policies and procedures should include ongoing and/or just-in-time training to ensure HCP are equipped to doff different PPE designs encountered during clinical care.

BACKGROUND: Personal protective equipment (PPE) helps protect healthcare workers (HCWs) from pathogens and prevents cross-contamination. PPE effectiveness is often undermined by inappropriate doffing methods. Our knowledge of how HCWs approach doffing PPE in practice is limited. In this qualitative study, we examine HCWs' perspectives about doffing PPE. METHODS: Thirty participants at a Midwestern academic hospital were recruited and assigned to 1 of 3 doffing simulation scenarios: 3 mask designs (n = 10), 2 gown designs (n = 10), or 2 glove designs (n = 10). Participants were instructed to doff PPE as they would in routine practice. Their performances were video-recorded and reviewed with participants. Semistructured interviews about their doffing approaches were conducted and audio-recorded, then transcribed and thematically analyzed. RESULTS: Three overarching themes were identified in interviews: doffing strategies, cognitive processes, and barriers and facilitators. Doffing strategies included doffing safely (minimizing self-contamination) and doffing expediently (eg, ripping PPE off). Cognitive processes during doffing largely pertained to tracking contaminated PPE surfaces, examining PPE design cues (eg, straps), or improvising based on prior experience from training or similar PPE designs. Doffing barriers and facilitators typically related to PPE design, such as PPE fit (or lack of it) and fastener type. Some participants also described personal barriers (eg, glasses, long hair); however, some PPE designs helped mitigate these barriers. CONCLUSIONS: Efforts to improve HCWs' doffing performance need to address HCWs' preferences for both safety and expediency when using PPE, which has implications for PPE design, training approaches, and hospital policies and procedures.
