Quality of clinical practice guidelines for frozen shoulder: a systematic review

Abstract

Objective: Perform a systematic critical appraisal of current clinical practice guidelines (CPGs) for frozen shoulder.

Literature survey: Systematic review of CPGs (PROSPERO number CRD42022368775). Inclusion criteria- CPGs written in English providing guidance on the evaluation and or treatment for frozen shoulder, traumatic injury and neurologic CPGs were excluded.Relevant studies were assessed for inclusion and selected studies were identified from PubMed, EMBASE, Scopus and CINAHL databases. The search strategy was developed by a biomedical librarian, performed on October 9, 2024.

Methodology: Data were extracted from the selected CPGs and underwent quality assessment using the Appraisal of Guidelines for Research and Evaluation (AGREE) II.

Synthesis: The search resulted in 38,428 studies and 2 CPGs were retained for appraisal. The mean overall AGREE II score was 75% (SD = 5.7). Lowest mean scores were found in the applicability (27% SD = 24.0) and editorial independence (48% SD = 14.1) domains. The highest domain scores were found in scope and purpose (92% SD = 7.8) and clarity and presentation (79% SD = 9.9). One CPG was rated as low quality based on a priori criteria and ultimately one higher quality CPG was recommended.

Conclusion: Given the advances in research that have developed over the last decade pertaining to the evaluation and treatment of frozen shoulder there is a critical need for an up to date, evidence informed, high quality CPG in order to identify gaps in our knowledge that the global research community should address.
