The direct costs of residency training in the United States are over $1 billion per year. These educational programs have been organized predominantly around hospital services and supported by hospital revenues. ⋯ Debate over the current sources of financing reveals several troublesome issues: the presence of residents allegedly decreases the productivity of professionals and leads to overusage of ancillary services, proposed methods to pay for faculty salaries and services have created confusion and concern, and the financing of ambulatory-care training has been insufficient and poorly coordinated. The medical-education community must resolve these professional and educational problems so that financing issues can be debated and properly defended.

Randomized Controlled Trial Comparative Study Clinical Trial
The chemotherapy of plasma-cell myeloma and the incidence of acute leukemia.
Previously untreated patients with myeloma were randomized to initial treatment with melphalan and prednisone (and to cyclophosphamide or carmustine if relapse or progression occurred)(Group A, 125 patients), melphalan, cyclophosphamide, carmustine and prednisone in alternating (Group B, 123 patients) or concurrent (Group C, 116 patients) schedules. The groups were similar with respect to known prognostic factors. Response rates and survival were also similar. ⋯ Myelomas producing only gamma chains have a poorer prognosis (P greater than 0.001) than IgG, IgA, or kappa myeloma. Acute leukemia has developed in 14 patients. The actuarial risk of developing acute leukemia, has increased rapidly to 17.4 per cent at 50 months.
