Quality and content analysis of clinical practice guidelines which include nonpharmacological interventions for knee osteoarthritis.

RATIONALE, AIMS, AND OBJECTIVES: Clinical practice guidelines (CPGs) for knee osteoarthritis (OA) guide the provision of high-quality healthcare for people with knee OA, which may improve outcomes. Our aim was to evaluate the quality of and content within recently published CPGs for people with knee OA.

METHODS

CPGs (2014-2019) that described recommendations for nonpharmacological interventions for knee OA were included in the analysis. Two pairs of evaluators used the Appraisal of Guidelines Research and Evaluation II instrument (AGREE II) to assess the quality of guideline development. CPG content was reviewed and summarized for comparison.

RESULTS

Ten CPGs were identified for inclusion in the quality and content analysis (seven newly developed and three recently updated). Overall CPG scores ranged between 42% and 100%. Six CPGs were found to be high-quality. Exercise was the only intervention recommended by all CPGs that we appraised. Weight-management and education were the next most frequently recommended interventions. Inter-rater reliability scores were high in domain 1: scope and purpose, (P-value = .001, intraclass correlation coefficient [ICC] = 0.90, 95% confidence interval [CI] = 0.62-0.98), domain 3: rigor of development (P-value = .000, ICC = 0.95, 95% CI = 0.80-0.99) and domain 5: applicability (P-value = .001, ICC = 0.91, 95% CI = 0.64-0.98).

CONCLUSION

Several CPGs have been developed or recently updated since 2014. Over half of the ten CPGs we appraised were deemed to be high-quality. Exercise, education, and weight-management advice are interventions that were most commonly recommended by CPGs.
