Introduction: context and hypothesis/aims Clinical laboratories play a vital role in ensuring patient safety (1). The American College of Pathology highlighted the importance of laboratory safety as early as 1946 (2). Laboratory tests provide essential information that influences diagnostic and therapeutic decisions,(3,4) with an estimated 60-70% of these decisions relying on test results (5). As a result, laboratory tests are an indispensable part of modern clinical diagnosis (6). Improving laboratory processes can thus contribute positively to disease prevention, diagnosis, treatment, clinical monitoring, and the reduction of operating costs (1,6). This study aimed to assess specimen rejection rates in the preanalytical phase over the past year and propose solutions by analyzing the reasons for specimen rejections through individual in-depth interviews with nurses. Methods and results: description of the methods used/study design/data collection. Presentation of the results addressing the study hypothesis/aims The study employed a mixed design, combining retrospective data analysis and individual in-depth interviews. It was conducted in two stages: first, data on specimen rejections from microbiology and biochemistry laboratories over one year were collected; second, purposive sampling was used to interview with nurses from units with the highest rejection rates. The study revealed that insufficient, hemolyzed and clotted specimens were the most common causes of rejection in biochemistry and microbiology laboratories. The highest number of specimen rejections occurred in internal units. In the analysis of individual in-depth interviews, three main themes were identified: the functioning of the preanalytical phase, the causes of medical errors in the preanalytical phase, and the effect of the preanalytical phase on the well-being of nurses. Discussion of the impact/outcome, and novelty of the Research Institutional factors, patient profiles, stakeholders involved in the phase, and the clinical setting all influence the preanalytical phase, potentially leading to medical errors; this phase also impacts the attitudes and behaviors of patients and their relatives, as well as the wellbeing of nurses, resulting in emotional fatigue. Despite these challenges, nurses strive to maintain their well-being and provide emotional support to patients and their families. Based on the findings of our study, there is a need for simulation-based training and strategies that focus on improving the preanalytical phase, ensuring nurses' well-being, and reducing emotional fatigue.
