The study aims to explore the impact of dimensions of the work environment, including training, incentives, technological empowerment, nature and conditions of work, and participation in decision-making, on the performance of healthcare personnel working in the Saudi health sector, from the perspective of healthcare workers in government hospitals in the Kingdom of Saudi Arabia. The descriptive-analytical method was used to achieve the objectives of the study, and the study sample included 112 individuals from healthcare personnel working in Al-Iman General Hospital in Riyadh, King Saud Medical City, and King Salman Hospital. The study utilized a questionnaire as a data collection tool, and the results showed that the multiple correlation coefficient (R square) for the independent variables, which are dimensions of the work environment, is 0.898, meaning that these variables explain 89.8% of the total variance in the performance of healthcare personnel in the government health sector in the Kingdom of Saudi Arabia. The results also demonstrated the validity of the model in predicting the performance of healthcare personnel through dimensions of the work environment. Based on the results, the study recommends the necessity of enhancing hospital management strategies to ensure the provision of modern technological facilities and medical equipment to improve task performance. It also recommends encouraging and empowering nurses within hospitals by increasing motivation levels and granting them greater authority, aiming to increase the sustainability and efficiency of their performance. Additionally, the study highlights the importance of providing all aspects of the work environment appropriately to enhance the performance of healthcare personnel and provide high-quality healthcare services. Furthermore, it recommends promoting training courses and programs that enhance the skills and experiences of healthcare personnel to improve their efficiency.
