Who attends Dunedin's free clinic? A study of patients facing cost barriers to primary health care access

Abstract

INTRODUCTION: Several methods of reducing the cost barrier to primary health care have been implemented in New Zealand, but research about free primary health care and the patients who use such services is scarce. AIM: To compare the characteristics of patients at Dunedin's free clinic with those at a traditional general practice clinic. METHODS: A written survey was distributed to waiting room patients at the Free Clinic and a fee-charging clinic in close proximity. Patient records were accessed to determine health services utilisation rates at both clinics and the discounting rate at the traditional clinic. RESULTS: There were 126 patient surveys returned at the Traditional Clinic and 65 at the Free Clinic. There was a significantly greater proportion of Maori respondents at the Free Clinic than at the Traditional Clinic (24.1% versus 9.2%, p=0.011). The difference in deprivation profiles of Free Clinic and Traditional Clinic respondents was more marked for the individual deprivation measure (five or more NZiDep deprivation characteristics: 65.5% versus 13.3%, p<0.001) than for residential area deprivation (NZDep2006 quintile 5: 41.4% versus 15.8%, p<0.001). Emergency department presentation rates were high for Free Clinic patients, despite free primary care access and high general practitioner consultation rates. Among Traditional Clinic respondents, 31.7% reported deferring health care because of cost in the previous 12 months. The equivalent figure for Free Clinic respondents was 63.8%. DISCUSSION: This survey suggests that Dunedin's Free Clinic serves a vulnerable population, in whom levels of unmet health need and health service usage are high.
