摘要

Although proper donning and doffing of personal protective equipment (PPE) is critical for infection prevention, detailed characterization of problems encountered during these processes in real-world settings during large-scale infectious disease outbreaks remains insufficient. This study aimed to analyze the characteristics and distribution of interception problems in the process of donning and doffing process in a large cabin hospital during the 2022 COVID-19 pandemic in Shanghai. A prospective, real-world study was designed to collect and analyze data on irregularities observed during personal protective equipment (PPE) donning procedures in cabin hospital operations. The proportion of problems encountered during donning PPE was 5.29% (246/4,652), while during doffing PPE, it was 8.44% (382/4,525) (P < 0.001). The primary problem during donning PPE was related to problems with protective clothing, followed by problems with respirators. There was no significant difference in problem distribution among different posts (P = 0.459). The problems related to protective clothing mainly focused on loose fitting around the head and neck, making them prone to exposure during donning (56.25%, 99/176) and contamination of the inner surface of protective clothing during doffing (46.43%, 91/196). Respirator-related problems included failure of the seal test during donning PPE (61.54%, 24/39) and shifting or loosening of the respirator during PPE doffing (73.68%, 14/19). These findings identify critical gaps in PPE procedures and highlight the need for targeted training to address these issues, thereby reducing the risk of infection among healthcare personnel in mobile cabin hospitals.
