Abstract
Purpose
Investigate components of care for rotator cuff related shoulder pain in workers’ compensation in relation to claim outcomes (claim duration, total medical spend, total claim cost, return to work outcome).
Methods
Engagement with (had care, time to care) four components of care (prescribed exercise, imaging, injections, surgery) were obtained from auditing 189 closed workers’ compensation files. Associations were analysed between components of care and claim outcomes.
Results
80% received prescribed exercise, 81% imaging, 42% injection and 35% surgery. Median time to imaging (11 days) was shorter than the prescribed exercise (27 days), with injection at 38 days and surgery 118.5 days. With univariable regression analysis higher age, the involvement of legal representation and the presence of rotator cuff pathology from diagnostic imaging (partial thickness tear or full thickness tear) were all associated with increased claim duration, total medical spend, total claim cost and less successful return to work outcomes. After adjusting for these three associations, having an injection or surgery were both positively associated with longer claim duration and greater medical spend, and surgery with greater total claim costs. In general, longer time to receiving components of care was associated with increased claim duration and reduced odds of returning to full duties at work.
Conclusion
Early management was not consistent with clinical guidelines for managing workers’ compensation rotator cuff related shoulder pain. This may negatively affect claims outcomes.

Clinical Significance
Early management of work-related shoulder pain did not align to clinical practice guidelines, with a potential over-reliance of imaging and comparative delay in starting prescribed exercise in this cohort. This may negatively affect claims outcomes and is worth targeting in pragmatic implementation trials.
Competing/Conflicting Interests
SR was employed part-time by the CGU Workers’ Compensation during the time this study took place. DB, TM and SR work as musculoskeletal physiotherapists in the WA workers’ compensation environment, in which they manage injured workers whose employers have policies with the insurer. The insurer had no influence on the production of this manuscript.
Informed Consent
All procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional and national) and with the Helsinki Declaration of 1975, as revised in 2000. A data access and confidentiality agreement was established between Curtin University and CGU for access to the CGU file records.
Ethics Approval
Ethical approval was obtained through Curtin University Human Research Ethics Committee (Approval Number HRE2018-0539). A data access and confidentiality agreement was established between Curtin University and the insurer.
Consent to Participate
Given the data was retrospective, participant permission could not be gained for this study, however the insurer had previously gained consent to acquire and maintain appropriate medical information upon lodgement of all participant’s workers’ compensation claims.
Consent to Publish
Workers compensation claims files were viewed in a secure area within the insurer’s premises and de-identified data was stored on password protected computers to avoid unauthorised dissemination of claim details. There is no identifying personal data (i.e. individuals details, images or videos) shared within this study which would require consent to publish.
