Abstract

OBJECTIVE:

To document the variability in consultation length and to examine the relative weight of different kinds of characteristics (of the patients, of the general practitioner (GP), or of the practice) in affecting consultation length, and, thus, to assess whether consultation length can legitimately be used as a quality marker.

DESIGN:

A multilevel statistical analysis of 836 consultations across 51 GPs in ten practices.

SETTING AND SUBJECTS:

Ten general practices across four regions in England with varying list sizes, number of partners and fundholding status.

MAIN OUTCOME MEASURES:

Length of time face-to-face with patients in consultation measured in minutes and fractions of minutes.

RESULTS:

There is substantial inter-practice variation in consultation length, from a mean of 5.7 minutes to one of 8.5 minutes. In some practices the longest average GP consultation time is about twice that of the shortest. Trainees and new partners spend, on average, about 1 minute less than their longer-serving colleagues. Consultation lengths for individual GPs range from a mean of 4.4 minutes to 11 minutes. Late middle-aged women (55-64 years) receive the longest consultations, followed by elderly people, with children receiving the shortest consultations. The number of topics raised affects the length of the consultation by about 1 minute per additional topic. When female patients consult female GPs, approximately 1 minute is added to the average consultation. A significant fraction of the variability in consultation lengths can be explained in terms of characteristics of patients, of GPs and of practices.

CONCLUSIONS:

The fact that there is little unexplained variation in GP consultation lengths that might be attributable to variations in quality (i.e. GP-related) throws doubt on the proposition that length of consultation can be used as a marker for quality of consultation in general practice.
