Damage due to human error has different consequences in different professions. Small mistakes can lead to irreparable damages and high costs in the health care profession. Therefore, the purpose of this study was to identify human error using the SPAR-H in clinical and pathology laboratories in hospitals of Qazvin province. Method: This study was a cross-sectional study which was conducted in 15 hospitals of Qazvin in 2018. The target groups was of professional staff in clinical and pathology laboratories comprised 150 staffs who they were included as an available sampling . At first, task analysis was conducted to target group using Hierarchical Task Analysis (HTA) technique by FGD. In next step, the Human Error Probability (HEP) was determined utilizing SPAR-H method and dependences of performance-shaping factors (PSFs) and action and diagnosis activities were identified. And finally, the errors were detected. Result: According to the findings of the study, in the laboratory, 12% of the diagnostic errors, 48% of the functional and 40% of the compound were evaluated. The most probable error was the error in entering the results and values from the manual recording to the computer with a 1% probability error and the least probable error was the Corrupted or lost samples with an error probability of 0.00125%. Conclusion: Considering the fact that the highest number of reported errors occurred at the patient's admission stage, including the inclusion of patient information and incorrect registration of the requested tests, and given the high volume of patients referred to hospital laboratories, especially public hospitals due to acceptance of treatment insurance And the low cost, it is necessary to allocate more personnel in the acceptance and response department.
