According to different studies, the prevalence of MEs ranged from 1 to 40%. ĭespite the development of diagnostic and treatment services, previous studies demonstrated an increase in ME events due to the complex issues of treatment and its timing. MEs increase the cost of hospitalization and medical expenses in both developed and developing countries which lead to decrease the quality of healthcare systems. According to various investigations at the global level, medication errors represents 10–18% of MEs, are placed in this category. There are various classification of MEs, technical errors, systematic errors (e.g., administrational organizational and process) and human errors (e.g., medication, diagnosis and treatment). MEs can occur in any care setting, including hospitals, health center, clinic, and laboratory, thus they can negatively effects on the patient safety. Medical error(s) (MEs) are known as a inevitable event in the health system. In this regards, providing enough education to nurses, improvement of patient safety culture and quality of services and attention to special wards, especially in teaching hospitals are suggested. Result of the comprehensive literature review of the current studies, found a wide variation in the prevalence of medical errors based on the occupational group, type of error, and health care setting. Based on the result of the random effect model, the overall estimated prevalence of medical errors was 50% (95% confidence interval: 0.426, 0.574). University or teaching hospitals (30 studies 75% of studies) as well as, internal/intensive care wards (10 studies 25% of studies) were the most frequent hospitals and wards detected. The most reported type of error was medication error (25 studies 62% of studies, with prevalence ranged from 10 to 80%). In 40 included studies, the most frequent occupational group observed were nursing staff and nursing students (21 studies 52% of studies).

Stata software was used for data analysis. The prevalence of medical errors was calculating using random effect model. The JBI appraisal instrument was used to assess the quality of included studies, by two independent reviewers. Article in English and Persian which estimated the prevalence of medical errors in Iran were eligible to be included in this review. The search was performed without time limitation up to January 2017 using the MeSH terms of Medical “error(s)” and “Iran” in Endnote X5. MethodsĪ comprehensive search was conducted in international databases (MEDLINE, Scopus and the Web of Science), national databases (SID, Magiran, and Barakat) and Google Scholar search engine. To clarify medical errors’ status in Iran, a review was conducted to estimate the accurate prevalence of medical errors. Medical errors are considered as a major threat to patient safety.
