Implementing international osteoarthritis guidelines in primary care: uptake and fidelity among health professionals and patients.

Abstract

OBJECTIVE\nThis paper evaluates the implementation fidelity of a strategy and intervention used to implement osteoarthritis (OA) treatment recommendations in primary care. We also evaluate uptake of core treatment (patient information, exercise and referral to weight management) among OA patients.\n\n\nDESIGN\nA stepped-wedge cluster-randomised controlled study (RCT) in primary care. The study involved general practitioners (GPs), physiotherapists (PTs) and patients with hip and/or knee OA in six Norwegian municipalities (clusters). Workshops for general practitioners (GPs) and PTs represented the main implementation activity. Uptake of core treatment (patient education, exercise and weight management) was evaluated using self-reported data from the patient intervention and control group, analysed with logistic regression models. Fidelity was evaluated using six components representing adherence to the content and dose instructions in the implementation strategy and assessed against a-priori criteria for high adherence.\n\n\nRESULTS\nData were collected from 40\xa0GPs, 37\xa0PTs and 393 OA patients. The patient-reported data showed statistically significant higher uptake for exercise, patient education and referral to support for weight reduction, among the intervention group compared to the control group (P\xa0<\xa00.05). Evaluation of fidelity showed high adherence to GP and PT workshop attendance and physiotherapy use, partly adherence to PT knowledge after workshops, and low adherence to exercise attendance, dose and progression instructions.\n\n\nCONCLUSIONS\nThe implementation strategy and intervention successfully improved OA patients access to physiotherapy and uptake of recommended core treatment. However, the strategy was less effective in providing exercise programs with sufficient dose and progression and in supporting patients adherence to the exercise program.\n\n\nTRIAL REGISTRATION\nClinicalTrials.gov NCT02333656.
