Objective: To investigate the prevalence, characteristics, and preventive status of skin injuries caused by personal protective equipment (PPE) in medical staff. Approach: A cross-sectional survey was conducted online for understanding skin injuries among medical staff fighting COVID-19 in February 8-22, 2020. Participants voluntarily answered and submitted the questionnaire with cell phone. The questionnaire items included demographic data, grade of PPE and daily wearing time, skin injury types, anatomical sites, and preventive measures. Univariable analyses and logistic regression analyses were used to explore the risk factors associated with skin injuries. Results: A total of 4,308 respondents were collected from 161 hospitals and 4,306 respondents were valid. The overall prevalence of skin injuries was 42.8% (95% confidence interval [CI] 41.30-44.30) with three types of devicerelated pressure injuries, moist-associated skin damage, and skin tear. Co-skin injuries and multiple location injuries were 27.4% and 76.8%, respectively. The logistic regression analysis indicated that sweating (95% CI for odds ratio [OR] 87.52-163.11), daily wearing time (95% CI for OR 1.61-3.21), male (95% CI for OR 1.11-2.13), and grade 3 PPE (95% CI for OR 1.08-2.01) were associated with skin injuries. Only 17.7% of respondents took prevention and 45.0% of skin injuries were treated. Innovation: This is the first cross-sectional survey to understand skin injuries in medical staff caused by PPE, which is expected to be a benchmark. Conclusion: The skin injuries among medical staff are serious, with insufficient prevention and treatment. A comprehensive program should be taken in the future.

Support surfaces remain an integral component of pressure injury prevention and treatment. Recent research and new technologies coupled with new standards testing created a need for revision of past terms and definitions related to support surfaces. These terms and definitions have been developed to provide a common understanding of terms that refer to basic physical concepts, design considerations, and product characteristics. Thus, the purpose of this document is to provide a glossary of terms and definitions that are specific to the language used within the Support Surface Standards Initiative, and serve as a lexicon to facilitate and provide clarity of understanding regarding performance evaluation and the standardized testing protocols. Based on the work of the Support Surface Standards Initiative (S3I) of the NPUAP, new terms and definitions were added, and all were compiled into an alphabetical list to facilitate ease of use. While this is a comprehensive and inclusive list, periodic review and revision is required. The bibliography, of necessity, includes classic references for terms for which the definitions have not changed. The foundational definition of a support surface used in this document is: "A specialized device for pressure redistribution designed for management of tissue loads, micro-climate, and/or other therapeutic functions (e.g. any mattresses, integrated bed system, mattress replacement, overlay, or seat cushion, or seat cushion overlay)."
