Although laboratory information management system is crucial for enhancing patient care and turnaround time, variables pertaining to LIMS that impact them must be investigated because there is lack of res Objective: To assess Patient satisfaction and Turnaround time while using Electronic laboratory information management system along with associated factors in selected public hospitals in Addis Ab Methods: A Hospital-based cross-sectional study was conducted at selected public hospitals by using both quantitative and qualitative data collection methods. The hospitals were selected using a simple random sampling method from a list of 13 public hospitals. Data was collected from 422 patient interviews and TAT recording for hematology and clinical chemistry tests as well as purposive selection of laboratory staffs with a total of 30 participants for structured questionnaire and in-depth interview. The collected data was coded and entered into excel and transferred to SPSS version 25 for further analysis. Both binary and multiple logistic regression analysis was used to see the association between dependent and independent variables. The findings were taken as significant with a p value of ≤ 0.05 at 95% confidence interval and results were presented with text, graph and tables. Aba, Ethiopia. Arch in Ethiopia that focus on this area. Result: The study’s response rate was 100%. 52.8% of respondents were male. The three hospitals’ overall mean scores for patient satisfaction were 3.3. Lab price and the courtesy and respect of staff were main sources of satisfaction; cleanliness of the latrines and seating arrangements, which were a major issue in all hospitals, were the main sources of dissatisfaction. Hematology tests that achieve target TAT was TASH 40.7%, SPMHMC 34.7% and ALERT 23%, also TAT achieved for clinical chemistry was TASH 52.7%, SPMHMC 56.7% and ALERT 39.3%. Turnaround time and patient care are impacted by issues like equipment failure, power outages, system outages, and unstable networks. Conclusion: Patient satisfaction and TAT in laboratory services is mostly dependent on effective laboratory management and infrastructure. Even though LIMS adoption has had a positive impact on operational efficiency; technical issues must be resolved, staff must be well trained, and a steady power and network supply must be ensured.enLaboratory information management system (LIMS)Turnaround time (TAT)Patient satisfaction.Thesis
