AbstractThis study fills a long felt need for recent reliable information about what happens in the over 80 million general practice consultations with 82% of the population each year. It provides a baseline of information against which the effect of the many of changes currently occurring in general practice can be assessed. The study was conducted over a one year period from October 1990 to October 1991, and for the first time relied on a stratified random sample of general practitioners. A final sample of 495 GPs recorded details of all surgery and home doctor-patient encounters for 2 one-week periods separated by a period of six months with the sample being spread evenly across the year. Two data files are provided. The first file (do644a.dat) gives data on characteristics of each general practitioner, the second (d0644b.dat) provides data for each consultation. Profiles of general practitioners include age and sex of the practitioner, years in general practice, practice size, language (s) in which consultations are conducted, medical qualifications, and membership of professional associations. Details of consultations conducted either at the GP's surgery or at the home of the patient include: date of consultation; major service item number; patient age, sex and status to the practice; up to 3 patient reasons for encounter; up to 4 problems managed; prescriptions and other treatments provided (up to 4 per problem); tests and investigations ordered (multiple groups); admissions; referrals to specialists or other health professionals (up to 2); and planned follow up within 3 months. Details of each encounter were recorded on a form designed specifically for this study and a limit of 200 recorded encounters within the week was set in consideration of the workload of busy doctors. Patient reasons for encounter and problems managed were classified in terms of the International Classification of Primary Care (ICPC), therapeutic treatments and advice in terms of IC-Process-PC, and drugs prescribed and referrals according to classifications developed by the study team.

A final sample of 495 GPs was used. Each GP recorded details of all surgery and home doctor-patient encounters for two one-week periods separated by a period of six months with the sample being spread evenly across the year. A limit of 200 recorded encounters within the week was set in consideration of the workload of busy doctors. Number of units in original sample: 1471 General practitioners
