Effects of Psychiatric Consultation on Medical Consumption in Medical Outpatients With Abdominal Pain

A randomized controlled clinical trial was conducted in an outpatient clinic of internal medicine to test the hypothesis that a protocol of cooperation and communication between internist and general practitioner, sustained with psychiatric consultation, would reduce medical consumption in a group of medical outpatients with abdominal pain (N = 106). A reduction in medical consumption could not be demonstrated. However, a great variation in protocol adherence was found, partly related to the severity of the psychological problems. There is some evidence that the protocol, if restricted to cases with more severe psychiatric comorbidity, might reduce medical consumption.
