Operating room teamwork performance in low- and middle-income countries, including Africa is understudied. Objective: The aim of this study was to assess teamwork performance and associated factors among Operating Room Professionals working in selected public hospitals, Addis Ababa Ethiopia, 2023. Methods: Institutional based cross-sectional study design was conducted at selected public hospitals from April, 01 to April, 30/2023. Five hospitals were chosen by lottery method, and operating room teams were recruited in proportion to the number of teams, followed by simple random sampling from the respective hospitals. The observation checklist was used to evaluate teamwork performance. A structured questionnaire was also used to collect basic professional information. Pretesting of instruments was performed and collected data were cheeked and entered in to Epi-data version 4.6 for data cleaning and imported to SPSS version26.0 software for analysis.Associations between independent and dependent variables were analyzed using a binary logistic regression model with bivariables and a multivariable logistic regression analysis technique. P-values < 0.05 were considered statistically significant. Results: The overall operating room professionals’ teamwork performance was poor, 121 (74.16%). Age of 31-40 years [(AOR=0.54, p=0.021; 95%CI (0.33, 0.76)], team familiarity [(AOR=3.56, p=0.01; 95%CI (2.51, 3.92)], cases being complicated/sever [(AOR=3.16, p=0.004; 95%CI (1.45, 6.90)] and availability of supplies [(AOR=1.5, p=0.004; 95%CI (1.58, 2.15)] were factors associated with teamwork performance. Conclusion and recommendations: This study concluded that, about 75% of operation room teams had poor teamwork performance compared to different literature in other parts of the world, where personal and organizational factors associated with teamwork performance. To protect patients undergoing surgery in the study area and elsewhere in the country, it needs to devise measures to improve operation room professionals’ teamwork performance such as training on soft skill (non-technical skills) technologyen-USSurgical team, Teamwork, Teamwork performance, EthiopiaThesis
