Objective: To measure the independent effect on length of general-practice consultations of a range of characteristics of the general practitioner (GP), practice, patient and consultation, as a basis for considering future GP workforce needs.
Setting and participants: Data were obtained from 1904 GPs Australia-wide on 70 758 consultations between 1 January 2001 and 31 December 2002; all consultations that were claimable from the Australian Government’s Medicare system as General Practice Attendances and had recorded start and finish times were included.
Results: The following variables had an independent positive effect on consultation length: GP female, older, graduated in Australia, FRACGP-qualified, and in rural practice; patient female, older, new to practice, with higher socioeconomic status, no health concession card, more reasons for encounter, and more problems managed; and management of specific problem types (social, psychological and female genital problems), management of chronic disease, and provision of clinical treatments.
Conclusion: The independent relationship of some GP, practice, patient and consultation characteristics with length of consultation may affect future GP supply. These factors should be considered in modelling future general practice workforce needs.
