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.

Face-to-face interaction compared with video watching on use of physical activity in peripheral arterial disease: a pilot trial.

Few studies have defined the association of physician-patient communication with physical activity levels in patients with peripheral arterial disease. We hypothesized that a face-to-face intervention versus video watching would improve physical activity levels in patients with peripheral arterial disease. The authors conducted a randomized trial involving 2 interventions. The face-to-face intervention included a brief dialogue with patients to understand their perceptions of peripheral arterial disease and importance of walking. The comparison group watched a video that included an overview of peripheral arterial disease. The primary outcome was changed from baseline to follow-up in levels of physical activity. Fifty-one patients with peripheral arterial disease were randomized. There were no statistically significant differences between the 2 groups in reported activity level or walking ability at 12 weeks. For within group changes, the patients in the video-watching group improved their walking speed (8.5%; SD = 4.1; P = .05). Patients with peripheral arterial disease may benefit from the use of an educational video to increase the use of unsupervised physical activity. Further research is needed to identify interventions that can increase the use of unsupervised physical activity in this population.

A qualitative approach to developing a patient-derived intervention to increase exercise in peripheral arterial disease.

OBJECTIVE: In designing a patient-physician communication intervention, we explored patients' perceptions of the role of exercise in the treatment of peripheral arterial disease (PAD). METHODS: We conducted qualitative interviews (5 focus groups and 13 one-on-one interviews) involving 35 patients with known PAD. We analyzed verbatim transcripts for significant dimensions of patients' explanatory models of PAD and exercise, perceptions of patient-physician communication, and other factors that would increase their participation in exercise (ie, walking). We used Atlas.ti software to facilitate data sorting and storage. RESULTS: Based on 30 emerging codes, we identified primary themes that constitute patients' perceptions of (1) the causes and outcomes of PAD, (2) the importance of patient-physician communication, (3) the impact of PAD on their lives, and (4) the factors that would lead to their exercise participation to treat PAD. From this information, our conceptual model focuses on an intervention plan that includes addressing the known causes of PAD, the patient's behavior prior to the diagnosis of PAD, and the factors that shape a patient's overall assessment of the role of exercise for PAD. An integral aspect of our model is the impact of the physician's perception of PAD coupled with the patient's perception in order to shape the intervention-a partnership between the physician and the patient-that we posit is likely to lead to behavior change. CONCLUSION: Based on qualitative data analysis, we developed a patient-derived model to influence exercise participation. This model highlights those factors most likely to influence behavior change in patients with PAD. The next step is to enact and assess an intervention based on this model, to increase physical activity in patients with PAD.
