Case mix and content of trainee consultations: findings from the north of England study of standards and performance in general practice.
BACKGROUND
Previous studies have examined the differences in the work of trainees and trainers. However, they have not investigated how many of these differences are due to differences in the case mix seen by trainees.


OBJECTIVE
A study was undertaken to investigate the effect of case mix on the content of consultations with trainee general practitioners.


METHODS
Details of surgery consultations with 207 trainee general practitioners and 255 principals in 62 training practices in the north of England were prospectively recorded during one week in each of four consecutive years.


RESULTS
Trainee general practitioners saw a higher proportion of younger patients and those categorized as suffering from an acute minor condition compared with principals. They saw a lower proportion of patients categorized as suffering from chronic intermediate, chronic major and female conditions. The reported content of trainee and principal consultations differed over all four years in that trainees examined more patients, issued more new prescriptions, issued fewer repeat prescriptions, arranged fewer return appointments and referred fewer patients. However, adjusting for case mix reduced the number of significant differences between trainees and principals to two: trainees issued fewer repeat prescriptions and had more consultations lasting longer than nine minutes.


CONCLUSIONS
The case mix and content of consultations differ between trainees and principals and some of the differences in content are due to the differences in case mix; trainees generally behave more like principals than has been previously suggested. Thus, case mix is an important factor in understanding the content of trainee consultations.
