By using the material obtained from the questionnaires returned by medical officers to the Committee on Postwar Medical Service, an estimate has been made of the probable number of house officerships in hospitals required after the war. Hospitals and medical schools will need to expand their educational facilities sufficiently to provide a high quality of training not only for the veterans but also for the new generations of physicians who will graduate from medical schools. On the basis of the estimated demand, the Council on Medical Education and Hospitals has communicated with all hospitals now approved for either residency or internship training. Replies have already been received from approximately one fourth of the approved institutions. The returns are encouraging, indicating that hospitals throughout the country are seriously planning for expanded educational opportunities and guarding at the same time against a lowering of the quality of the training offered.
