정신건강의학과 환자안전사고 분석(2017-2021)

Abstract

The study was undertaken to investigate the occurrence and risk levels of patient safety incidents in the mental health department of domestic medical institutions, aiming to provide essential data for formulating strategies to prevent such incidents in the future.
 The data for this study were collected nationwide from medical institutions accredited by the Korean Institute for Healthcare Accreditation, with a focus on patient safety statistics. A total of 521 cases from comprehensive and tertiary hospitals with more than 200 beds, classified under the department of mental health and psychiatry, were analyzed. Data analysis was performed using SPSS/WIN 27.0 software, encompassing descriptive statistics, cross-tabulation analysis, and binary logistic regression.
 The results showed that the number of patient safety incidents increased slightly in 2020 and 2021 compared to 2017. However, the level of harm caused by these incidents indicated a trend of increasing near misses and decreasing adverse events from 2017 to 2021. Comprehensive hospitals had a significantly higher proportion of adverse events in patient safety incidents compared to tertiary hospitals. The results of binary logistic regression analysis revealed that comprehensive hospitals had a 2.459 times higher risk of adverse events compared to tertiary hospitals. When comparing incident types, the risk of adverse events for falls was 10.677 times higher, and for suicide and self-harm events, it was 66.103 times higher compared to medication errors. Regarding age groups, the risk of adverse events for the 20-39 age group was 3.335 times higher compared to the 0-19 age group. For the 40-59 age group, the risk was 4.911 times higher for the 60-79 age group, it was 5.340 times higher, and for the 80 years and above age group, it was 4.027 times higher . The goodness of fit test for the final model indicated a good fit, and the model's explanatory power was 30.2%.
 Based on the study results, there is a need for a systematic analysis of nursing staff levels in comprehensive hospitals and their relationship with patient safety incidents and it is crucial to prioritize comprehensive hospitals when devising patient safety incident prevention measures in mental health. Suicide and self-harm prevention, and fall prevention strategies, should be considered as indispensable components. Furthermore, it is recommended to give priority to implementing patient safety incident prevention strategies for individuals aged 60-79 years of age.
