Socio-economic characteristics of adult frequent attenders in general practice: secondary analysis of data

OBJECTIVE: This study was carried out to determine the effect of a range of socio-economic features on frequent attendance in general practice from a large database of general practice consultations using two definitions of frequent attendance. METHODS: Secondary analyses were carried out of data from the Fourth National Survey of Morbidity in General Practice covering 60 general practices in England and Wales. A total of 283 842 adult patients and their consultations between September 1991 and August 1992 were examined. The main outcome measure was the odds ratio of being a frequent attender (95% confidence intervals). RESULTS: Using a definition of 12+ consultations/year, men were less likely to be frequent attenders (OR 0.14, 95% CI 0.13-0.17); however, the difference between men and women lessens with age. Patients who were more likely to be frequent attenders included those who were divorced or widowed (1.41, 1.31-1.51); from social classes IIIM (1.23, 1.17-1.29) and IV/V (1.33, 1.26-1.41); South Asian people (1.38, 1.16-1.65); or unemployed (1.61, 1.46-1.77). Other factors signifying isolation or poverty were also linked to frequent attendance. Using the definition of '6+ consultations for minor problems' produced broadly similar results although the relative weight of the factors showed some differences. CONCLUSIONS: Socio-economic factors were important indicators of frequent attendance in general practice. Results were very similar using either definition, suggesting that both are valid for further work. Furthermore, frequent attendance is a complex process associated with many factors outside the control of the GP.
