Editor—Freeman et al plead for longer consultations in British general practice.1 A pilot study performed with six general practitioners in Glasgow shows that breaking the habit of short consultations may be difficult and longer consultations may lead to higher health service costs.
Our study piloted a randomised controlled trial of the effect of an increased booking interval on identification of the patient's psychological distress.2 Each doctor's surgery was randomised to either 10 minutes per patient (the normal booking interval) or 15 minutes. One of us (MS) offered locum sessions to make up the shortfall in available consultations. We recorded 65 consultations at each booking interval for each practitioner. After the consultation, patients completed the general health questionnaire-12; doctors estimated psychological distress using a six point scale and recorded important outcomes of the consultations. Consultations were timed by a research assistant.
Data were collected from 781 consultations. When booking interval was increased by 50% consultation length increased by 12%, from 8.7 minutes to 9.7 minutes. Longer booking intervals significantly increased the number of consultations in which the doctor arranged investigations (19.4% v 27.9%; P=0.0069) and follow up appointments (43.8% v 53.7%; P=0.0072). There was no significant effect on the proportion of consultations in which prescriptions were issued (51.0% v 54.7%; P=0.34), physical examination carried out (66.8% v 66.8%; P=0.96), or referral made (14.0% v 10.7%; P=0.20).
There were no significant differences in identification of psychological distress between long or normal booking intervals (odds ratio 1.00 (95% confidence interval 0.63 to 1.59)).
Although booking interval increased by 50%, consultation length increased by only 12%. This raises the question of what the doctors did with the extra time. It has been argued that increasing the length of consultations will save time and resources. Our results suggest that the opposite is true; doctors ask more patients to make follow up appointments after longer consultations and perform more investigations. Perhaps doctors given more time with patients simply uncover more problems. The lack of impact of an increased booking interval on the recognition of psychological distress in patients suggests that structural constraints are insufficient to explain low rates of recognition of distress by general practitioners.
Our results must be interpreted with caution. A more sustained intervention might have led to more major changes in consulting behaviour. Our data suggest, however, that longer consultation intervals may cost more than remuneration for extra general practitioners' time.
