Background. Critical thinking is one of the most important missions of the educational planning system of medical sciences universities around the world. Hence, identifying the level of critical thinking skills and tendency of medical sciences students to think critically is of great importance. Therefore, the aim of this systematic review was to examine the critical thinking level in medical sciences students in Iran. Methods. To extract published studies in the field of critical thinking in Iran, a search was conducted in the databases of PubMed, Web of Science, Scopus, ERIC, and Magiran. The keywords of critical thinking, medical sciences, and Iran were used for the purpose of the search in the two languages of Persian and English and without any time limit. The PRISMA flow diagram was applied for the selection of articles, and the Newcastle–Ottawa Scale was used for the evaluation of these papers. Results. After evaluating the quality of searched articles, 80 articles were finally selected for the final analysis. The total sample of the articles included 12,578 students. The results indicated that out of 51 articles conducted in the field of critical thinking skills, 48 articles reported these skills at a low level, 2 papers at a medium level, and only 1 paper at a high level in the medical sciences students. Among 29 articles in the field of the level of critical thinking disposition, 13 articles reported their tendency level at a low level, 11 articles at a medium level, and 5 articles at a high level. Conclusion. In general, based on most articles, the level of critical thinking skills in the medical sciences students in Iran was reported to be at a low level and their tendency to critical thinking at a moderate level and low level. Therefore, given the importance of critical thinking for medical sciences students, future studies should consider factors influencing the increase of the critical thinking level in these students. In this regard, formation of some training workshops can also be promising. Furthermore, reviewing the medical sciences curriculum should be taken into consideration by the policymakers and educational planners so as to strengthen the level of critical thinking in the medical sciences students.

伊朗医学生的批判性思维水平

背景。批判性思维是全球医科大学教育计划系统的最重要任务之一。因此，确定批判性思维技能的水平和医学生批判性思维的倾向非常重要。因此，本系统综述的目的是检验伊朗医学专业学生的批判性思维水平。方法。为了提取伊朗批判性思维领域的已发表研究，在PubMed，Web of Science，Scopus，ERIC和Magiran的数据库中进行了搜索。批判性思维，医学和伊朗等关键字用于搜索的目的是波斯语和英语两种语言，没有任何时间限制。PRISMA流程图用于文章的选择，纽卡斯尔-渥太华量表用于评估这些论文。结果。在评估了搜索文章的质量之后，最终选择了80篇文章进行最终分析。文章的样本总数为12,578名学生。结果表明，在批判性思维技能领域中发表的51篇文章中，有48篇文章在医学专业学生中报告了这些技能的水平较低，其中2篇中级水平，只有1篇高级水平。在批判性思维倾向领域的29篇文章中，有13篇报道了其倾向性水平处于低水平，11篇报道了其中度水平，5篇处于高层。结论。通常，根据大多数文章，据报道，伊朗医学系学生的批判性思维能力水平较低，而他们倾向于批判性思维的趋势则处于中等和低水平。因此，鉴于批判性思维对医学生的重要性，未来的研究应考虑影响这些学生批判性思维水平提高的因素。在这方面，成立一些培训讲习班也很有希望。此外，决策者和教育计划者应考虑对医学课程的审查，以提高医学生的批判性思维水平。
