Background: In the Netherlands over 1.2 million people have OA of which almost half have knee OA. Recently, several international and national guidelines and quality standards have been developed and adopted to improve the quality of knee OA care. Mapping the patient perspective is a valuable and important step to get insight into the current status of the quality of knee OA care and the uptake of the quality of care standards endorsed by current guidelines. Objectives: To investigate the quality of knee osteoarthritis care from the patients’ perspective in the Netherlands. Methods: Members of a large observational prospective cohort (n=622), consisting of people clinically diagnosed or suspected with knee OA, were invited to compete an online survey. Besides demographic characteristics participants were inquired whether they contacted a health care professional(s) in the last year for their knee OA and, to fill in a slightly adapted version of the “OsteoArthritis Quality Indicator (OA-QI) questionnaire. In addition, participants rated the quality of knee osteoarthritis care in the Netherlands on a 10-point scale (1: very poor - 10: excellent), and were invited to make recommendations for knee OA healthcare improvement via open-ended questions. Results: Between September and October 2019, 434 participants completed the survey. Preliminary results show that most participants (78%) contacted one or more health care professional(s) for their knee OA complaints in the last year; most often an exercise and/or physical therapist (53.2%), the general practitioner (43.8%) and/or an orthopedist/orthopedic surgeon (41.5%). Furthermore, there were large variations in self-reported quality indictor achievements (checked “Yes”) with the lowest rate for referral for weight reduction and, the highest rate for advice on managing/living with osteoarthritis (table 1). On average, a score of 6.5 was given by the participants for the quality of knee OA healthcare in the Netherlands. Participants’ suggestions for OA care improvement ...
