Objective. We aimed to determine changes in workload in general practice associated with the postal administration of a health needs questionnaire. Method. We carried out controlled before-and-after intervention study of the effects of delivering a postal questionnaire to assess needs for care for patients with arthropathies of the hip and knee, groin hernia and varicose veins, and to assess health service utilization, general health status and risk factors for cardiovascular disease. The setting was a seven-partner, fundholding, group practice in Avon. The subjects were patients registered with an NHS group practice situated in Backwell and Nailsea, Avon. The outcome measures were the frequency of consultation, home visits and night visits, reasons for consultation, referral to specialist agencies and patterns of prescribing. Results. There was no significant difference between the study and control group in the year before and the year after the postal administration of the questionnaire with respect to changes in overall frequency of consultation, frequency of referral (including type of referral) and frequency of prescribing of non-steroidal anti-inflammatory drugs. In the study group there was a significant (P < 0.05) reduction in the number of daytime home visits and prescriptions written for analgesics. Analysis of the records of those who had received a medical examination, in addition to a postal questionnaire, showed that there was no significant difference between the study and control group with respect to frequency of consultation, referral to outside agencies or items prescribed. Conclusion. Administration of a health needs questionnaire to patients registered with this general practice was not associated with an increase in consultation frequency or referral, or a change in prescribing patterns. No plausible explanation could be identified for the significant reduction in the number of home visits and prescriptions written for analgesics. It was concluded that these results were a statistical artefact. On the basis of the evidence from this study, GPs can be reassured that the administration of health needs questionnaires of the type used in this study will not result in any increase in workload or costs of care incurred by increased referrals to outside agencies or increased prescribing.
