Estimating the balance of general practice versus family planning clinic coverage of contraception services in London.
OBJECTIVE
To compare levels of provision of contraception from general practice and family planning clinics for the populations of the 32 London Boroughs.


METHODS
Retrospective analysis of routine activity data, including the estimated numbers of first attendance, for 295 family planning clinics (managed by 28 NHS Trusts) and more than 1800 GP partnerships in Greater London, supplemented by data from a survey of family planning clinics. The results were expressed as the estimated percentage of women aged 16-49 obtaining advice on contraception from GPs and family planning clinics. These results were compared to those expected based on results in the General Household Survey.


RESULTS
Across London in 1995/96, 12% of women aged 16-49 obtained contraception services from family planning clinics, and 24% obtained contraception services from a GP. At a borough level there was variation from 11% to 25% in coverage by family planning clinics, and from 11% to 41% in coverage by GPs. Estimates of the proportion of women in this age group not using NHS-provided medical or surgical contraception ranged from 0 to 30%. Across all boroughs, there was no consistent relationship between levels of GP activity and family planning clinic activity.


CONCLUSIONS
The results indicate substantial variations between boroughs in the proportion of women using NHS-provided medical or surgical methods of contraception. The absence of any clear inverse relationship between activity in family planning clinics and activity in general practice suggests that changes to one will not be compensated by changes in the other. More specifically, health authorities that opt to purchase lower levels of family planning clinic activity cannot assume that women may opt to use GPs as an alternative. Such a strategy may increase the likelihood that women who would have used family planning clinic services will either not use contraception at all, or will use less effective 'over the counter' methods.
