Background/Purpose:

Hip and knee OA is frequent and is one of the leading causes of global disability. Population-based data of health care practices and consumption are scarce. The aim of the project was to describe health care consumption of a representative sample of patients with knee or hip symptomatic OA.

Methods:

The KHOALA (Knee and Hip OsteoArthritis Long term Assessment) cohort is a representative population-based multicenter cohort of 878 patients with symptomatic knee and/or hip OA, aged between 40 and 75 years old, established between 2007 and 2009. This study is an analysis of the 3 first years of the cohort follow-up. Patients filled in self-reported questionnaires annually.

Results:

The majority (N=698, 82%) of patients were followed up by their general practitioner and few by a rheumatologist (N=120, 14%). Twenty per cent (N=163) received NSAIDs during the past 3 months at an average of 50 to 56% of the maximal dose over time. Between 30 and 32% (N=268) of patients received grade 1 analgesic and between 20 and 23% (N=195) grade 2. Less than 15% of patients had steroids or hyaluronic injections.

Only 127 patients (15%) have been treated by physiotherapy and 59 (7%) by spa therapy. Almost 10% (N=86) of the patients used a technical aid mainly a walking stick. During the first 3 years of the cohort, between 15 and 19 total knee replacement surgeries and between 9 and 14 total hip replacement surgeries per year have been performed.

More than a third of the patients had blood tests or imaging exams, X rays being the most frequent. During the year before inclusion 120 (14%) patients have been hospitalized while during the follow up between 21 and 25% of patients have been hospitalized per year. Analgesic use was more frequent in women, in patients with a lower level of education, more comorbidities, retired, smoker and not taking alcohol more than 20g a day.

Conclusion:

These results are important data to describe current care practices and health care use in France in a representative population based cohort of patients with knee and/or hip OA.
