This study aims to investigate the effects of periodic self-assessments on materials management within the framework of quality management in healthcare. The retrospective study, conducted in a university hospital, evaluates the effectiveness of quality improvement initiatives and compliance with health standards, while examining in detail the effects of these processes on materials management. It also investigates how self-assessment processes improve healthcare service delivery and contribute to materials management processes. Problems identified through Fishbone and Pareto analysis are examined, prioritised and solutions are developed. The findings obtained aim to improve material management processes and increase quality standards in health. The main purpose of the research is to examine the effects of periodic self-assessments on materials management in order to improve the quality of healthcare services. The findings emphasise the importance of maintaining quality standards in health services and systematic handling of periodic self-assessments. Problems identified by Fishbone and Pareto analysis are analysed by root cause analysis and solutions are developed. This approach aims to contribute to the development of materials management processes and to the improvement of quality standards in healthcare. The results of the research are an important guide for practitioners, managers and policy makers in the fields of quality management and materials management in health services.
