Critical Thinking Skills in Health Care Professional Students: A Systematic Review

Background and Purpose. The purpose of this systematic review is to determine if critical-thinking skills in health care professional students change as a result of participating in a health care professional education program, and to assess the quality of the evidence evaluating this change. Method/Model Description and Evaluation. The study design was a systematic review. Six electronic databases were searched. Articles were graded using the Evaluation Guidelines for Rating the Quality of an Intervention Study. Outcomes. Eighteen articles were identified as meeting the inclusion criteria. Ten articles were identified in nursing, 5 in physical therapy and occupational therapy, 2 in pharmacy, and 1 in medicine. The scores on the Evaluation Guidelines for Rating the Quality of an Intervention Study ranged from 17 to 26 out of 48. The intraclass correlation of the 2 raters on the Evaluation Guidelines for Rating the Quality of an Intervention Study was 0.87. Eight studies in nursing, 2 studies in physical therapy, 1 study each in occupational therapy, pharmacy, and medicine showed statistically significant change in criticalthinking skills. Discussion and Conclusion. The evidence measuring the acquisition of criticalthinking skills in the fields of physical therapy, occupational therapy, pharmacy, and medicine is scarce. In nursing, although the majority of the studies support the acquisition of critical- thinking skills, none of the studies established appropriate sample size and statistical power analysis, and the cross-sectional studies did not perform group matching beyond sex and age. In physical therapy, the results are mixed and the studies lack adequate statistical power. In occupational therapy, pharmacy, and medicine, the studies that showed a statistically significant increase in critical-thinking skills had relatively small sample sizes and weak statistical power. There is a need for additional welldesigned studies looking at the acquisition of critical-thinking skills in all health care fields.
