Recorded quality of primary care for osteoarthritis: an observational study.
BACKGROUND
Osteoarthritis is the most common chronic disease in the UK, with greater prevalence in women, older people, and those with poorer socioeconomic status. Effective treatments are available, yet little is known about the quality of primary care for this disabling condition.


AIM
To measure the recorded quality of primary care for osteoarthritis, and assess variations by patient and/or practice characteristics.


DESIGN OF STUDY
Retrospective observational study.


SETTING
Eighteen general practices in England.


METHOD
Records of 320/393 randomly selected patients with osteoarthritis (response rate 81%) were reviewed. High-quality health care was specified by nine quality indicators. Logistic regression modelling assessed variations in quality by age, sex, deprivation, severity, time since diagnosis, and practice size.


RESULTS
There was substantial variation in the recorded achievement of individual indicators (range 5% to 90%). The percentage of eligible patients whose records show that they received care in the form of information provision ranged from 17% to 30%. For regular assessment indicators the range was 27% to 43%, and for treatment indicators the range was 5% to 90%. Recorded achievement of quality indicators was higher in those with more severe osteoarthritis (odds ratio [OR] 1.38, 95% CI=1.13 to 1.69) and in older patients (OR 1.14, 95% CI=1.02 to 1.28). There were no significant variations by deprivation score.


CONCLUSION
This study has demonstrated the feasibility of using existing robust quality indicators to measure the quality of primary care for osteoarthritis, and has found considerable scope for improvement in the recording of high-quality care. The lack of variation between practices suggests that system-level initiatives may be needed to achieve improvement. One challenge will be to improve care for all, without losing the equitable distribution of care identified.
