The health economic analysis of surgery versus rehabilitation in non-traumatic musculoskeletal shoulder disorders: A systematic review of trial-based studies.

Abstract

Objective: Non-traumatic musculoskeletal shoulder disorders are common. Their treatment, surgical or non-surgical, is associated with a considerable financial burden to health systems. The aim of this study was therefore to investigate the cost-effectiveness of surgical or rehabilitative treatments in this population.

Data sources: PubMed, Embase, NHS Economic Evaluation Database, Cost-Effectiveness Analysis registry, PEDro Database, Cochrane Library, and Google Scholar.

Review methods: Trial-based economic evaluations assessing nonoperative and/or operative interventions for the management of non-traumatic shoulder disorders, published from January 2000 to October 2024, were searched. The selection process, data extraction and quality assessment (carried out with the Quality of Health Economic Studies instrument) were independently conducted by two reviewers.

Results: Four studies (883 patients) were included in the review. Subacromial decompression for rotator cuff-related shoulder pain was found not to be cost-effective when compared with physiotherapy. Although it was not as cost-effective, Physiotherapy could be a socially beneficial alternative to mobilisation under anaesthesia in the early management of a frozen shoulder, due to lower costs and the delays in accessing surgical management in the pain-predominant phase. Productivity loss was the main driver of costs. It was not possible to determine the cost-effectiveness of other shoulder-related disorders due to sparsity of evidence.

Conclusion: Priority should be given to interventions that reduce productivity loss and facilitate patients' return to work as soon as possible. There is a definite need for multiplication and standardization of high-quality economic studies (and the trials they are based on) regarding the management of non-traumatic musculoskeletal shoulder disorders.
