The Use of Quality Improvement in the Physical Therapy Literature: A Scoping Review
Introduction:
Quality improvement (QI) is a useful methodology for improving healthcare, often through iterative changes. There is no prior review on the application of QI in physical therapy (PT).
Purpose And Relevance:
To characterize and evaluate the quality of the QI literature in PT.
Methods:
We searched four electronic databases from inception through September 1, 2022. Included publications focused on QI and included the practice of PT. Quality was assessed using the 16-point QI Minimum Quality Criteria Set (QI-MQCS) appraisal tool.
Results:
Seventy studies were included in the review, 60 of which were published since 2014 with most ( n = 47) from the United States. Acute care ( n = 41) was the most prevalent practice setting. Twenty-two studies (31%) did not use QI models or approaches and only nine studies referenced Revised Standards for QI Reporting Excellence guidelines. The median QI-MQCS score was 12 (range 7-15).
Conclusions/Implications:
Quality improvement publications in the PT literature are increasing, yet there is a paucity of QI studies pertaining to most practice settings and a lack of rigor in project design and reporting. Many studies were of low-to-moderate quality and did not meet minimum reporting standards. We recommend use of models, frameworks, and reporting guidelines to improve methodologic rigor and reporting.
