Abstract: t Objective: To analyze the knowledge of neonatal iatrogenic skin injury(NISI) and its high-risk factors among nurses in neonatal ward, and to provide the basis for preparing a scientific and practical risk assessment scale for NISI. Methods: A total of 205 nurses were included from the neonatal units and a self-compiled questionnaire survey were conducted in Tianjin in November 2021. Results: The most common clinical types of NISI were medical adhesive-related skin injury (MARSI), drug extravasation skin injury, and medical device-related pressure injury (MDRPI). Pareto plot and goodness-of-fit test results showed that skin condition, adhesive bonding time, type of adhesive, gestational age and body weight were main risk factors for MARSI, and their cumulative ratio was 78.53% . The main risk factors for drug extravasation injury were the nature of infusion drug, placement, preterm birth and low body weight and type of placement，and their cumulative ratio was 77.62%. The main risk factors for MDRPI were gestational age, weight, mobility, nutrition and skin immersion, and their cumulative ratio was 79.44%. Chi-square test showed that whether nurses have used risk assessment scale related NISI in clinical practice influenced their willingness to apply related scale and their opinion about the effect of application scale on clinical workload and quality of nursing(P<0.01). Conclusion: MARSI, drug extravasation injury and MDRPI were the most common types of NISI in the clinic. Different types have different kinds of high-risk factors, while gestational age and body weight are their common high-risk factors. Nurses in neonatal ward believe that the clinical application of injury risk assessment scale can reduce the nursing workload and improve the quality of nursing care to some extent, and they have a willingness to use such scale in clinical practice. Therefore, it is necessary to compiling a scientifically practical scale to predicting the risk of developing neonatal iatrogenic skin injury.
