11th EORNA Congress Valencia, Spain | 16 - 18 May 2024 ePoster Guided View 32 496 Self-assessment of nursing skills in the Operating Room: a literature review Mariaserena Piccioni1, Gilda Pelusi2, Rosa Stoico1, Ilaria Franconi1 1Reunited Hospitals Torrette of Ancona, Operating Room Block, Torrette, Italy, 2Marche Polytechnic University Faculty of Medicine, Ancona, Italy Background: Operating room nurses are required to have theoretical knowledge and technical skills. Competence in the perioperative setting is a difficult concept to define and measure. Assessment tools are necessary to evaluate operating room nurses’ technical and non-technical competencies. Objective The aim of the present study is to identify a validated instrument that allows subjective assessment of competency for all roles performed by the Operating Room nurse. Methods: A literature review based on Cochrane recommendations was conducted. The review protocol was edited according to PRISMA criteria. Data were retrieved by consulting six of the major available databases, analyzing the bibliographic references and citations of the included studies. All research processes were conducted between June and July 2022. Interrater reliability was calculated using the Krippendorff test. Each included study, being cross-sectional, was evaluated using STROBE. Results: A total of 709 articles were retrieved by database search (n= 370, 52.2%) and additional searches (n= 339, 47.8%). Duplicates were removed and relevance assessed. At the end of the title and Abstract screening phase, 11 articles were obtained on which the review was conducted. All articles were included in the review. The risk of bias was considered acceptable. The most frequently used validated rating scale (n= 8, 72.7%) was the Perceived Perioperative Competence Scale - Revised (PPCS-R). In 2021 in China, the Core Competence Scale (CSS) was validated. All studies agree that applying a competency assessment scale in this setting allows for a positive implication in managing work activity and staffing needs. Conclusion: The PPCS-R rating scale turns out to be the most widely used and investigates the main facets of hard and soft skills, highlighting crucial aspects to best understand the strengths and weaknesses of a work situation. Its wide use would allow further international comparisons to be made. 455 A study on the proper expiration date of sterilized products according to packaging materials Hyeuiyoung Kim1, Yeon Hee Jang1 1The Catholic University of Korea St. Mary’s Hospital, 4F Operating Room, Seoul, Korea, Rep. of South Background: The expiration date of sterilized products vary depending on the packaging materials. Therefore, it is necessary to prepare accurate information that can maintain the product in the safest and sterile state for a long time according to the storage environment, packaging materials, etc. Objectives: In order to examine an appropriate expiration date of sterilized products by packaging materials, the temperature and humidity of storage environment and the contamination of sterilized products were observed at E Hospital of C University in Seoul from February to September on 2023. Methods: The average and standard deviation of the storage environment were analyzed using Micro-soft office professional Plus 2016 EXCEL (STDEV). 360 samples of linen and nonwoven packaging and 108 samples of sterile bags were calculated and placed in 6 departments. Microbiological examination were conducted every 2 weeks, 3 for each packaging material. Results: The overall average temperature was 21.57+2.14℃ and humidity averaged 44.60+16.8% overall in the storage environment. One out of samples wrapped in linen and two out of samples wrapped in nonwoven fabric was contaminated in the 10th microbiological examination. In case of sterile pouch, bacterial contamination was observed in one sample in the first microbiological examination. After that, no bacterial contamination was observed until the fifth examination. Conclusion: It was found that the average temperature and humidity of the sterilized product storage environment were
