Cost-effectiveness Analysis in Diagnostic Musculoskeletal Radiology: A Systematic Review

Diagnostic musculoskeletal imaging represents a large economic expenditure within the health care system. Cost-effectiveness analysis can identify the most efficient use of imaging resources, but the literature is not well summarized. The purpose of this study was to summarize the existing literature on this topic and identify areas for future research. A systematic review of the literature was performed for 1995 - 2020. Data was extracted and summarized from those studies meeting inclusion criteria including publication and analysis characteristics and clinical topics. The search found 27 studies meeting inclusion criteria of which 16 (59%) were published in the last 5 years. Studies were clustered around specific topics with 21 (78%) of studies analyzing either osteoporosis screening (n = 9, 33%), cancer imaging (n = 4, 15%), inflammatory arthritis (n = 4, 15%), or spinal trauma (n = 4, 15%). Only 4 studies (15%) were published in radiology journals. Although 12 studies (44%) had a radiologist author, only 8 (30%) had a radiologist as first or senior author. Existing cost-effectiveness analyses in musculoskeletal radiology are clustered around a small number of topics and few studies are led by radiologists. Future research should target under-represented clinical topics and radiologists should actively pursue involvement in this field to apply their unique expertise and understanding of imaging.
