Subspecialty consultations in a teaching hospital.

A chart review of 60 consultations by the nephrology service of a teaching hospital was carried out to determine their diagnostic and therapeutic utility. General medicine residents on elective rotations in nephrology performed 72% of the consultations, only 26% being written by residents in the subspecialty. Consultants made an average of 2.2 diagnoses per patient, of which 57% confirmed the working diagnosis already in the medical record. They made an average of 3.0 recommendations for further investigation per patient, but referring physicians implemented only 58% of these. An average of 1.6 recommendations for therapy were made per patient, of which 64% were implemented. The apparent neglect of the consultant's advice for investigation and therapy suggests that the written consultation to some extent fails to convey information useful for the referring physician and the patient. Further study is needed to determine if this failure reflects inadequate training of house officers as consultants.
