Less than half of patients in secondary care adheres to clinical guidelines for subacromial pain syndrome and have acceptable symptoms after treatment: A Danish nationwide cohort study of 3306 patients.

Background: Evidence-based guidelines recommend exercise-therapy as first line treatment for subacromial pain syndrome, but no previous study has mapped the content of care for subacromial pain syndrome and knowledge about adherence to clinical guidelines are lacking. We aim to describe the content and outcome of current care and investigate the relationship between content and outcome of care.

Methods: We invited all patients diagnosed with subacromial pain syndrome at any Danish hospital to participate in this nationwide retrospective population-based cohort-study.
