The annual surveys of residency programs on which this statistical report is based have had a higher than 95% response for the past four years. The number of accredited programs increased in 1984 and again in 1985, primarily as a result of the accreditation of additional subspecialty programs. Discussions about the sources and methods of financing graduate medical education may have an impact on the number and the size of programs in the near future. ⋯ The number of new entry residents (PGY-1) decreased in 1983 (when the number of US graduates had decreased), increased in 1984, and decreased again in 1985. Forty-two percent of residents were training in family practice, internal medicine, or pediatrics. This statistic has not changed significantly over the past three years.

Randomized Controlled Trial Clinical Trial
Disulfiram treatment of alcoholism. A Veterans Administration cooperative study.
We conducted a controlled, blinded, multicenter study of disulfiram treatment of alcoholism in 605 men randomly assigned to 250 mg of disulfiram (202 men); 1 mg of disulfiram (204 men), a control for the threat of the disulfiram-ethanol reaction; or no disulfiram (199 men), a control for the counseling that all received. Bimonthly treatment assessments were done for one year. Relative/friend interviews and blood and urine ethanol analyses were used to corroborate patients' reports. ⋯ Among the patients who drank and had a complete set of assessment interviews, those in the 250-mg disulfiram group reported significantly fewer drinking days (49.0 +/- 8.4) than those in the 1-mg (75.4 +/- 11.9) or the no-disulfiram (86.5 +/- 13.6) groups. There was a significant relationship between adherence to drug regimen and complete abstinence in all groups. We conclude that disulfiram may help reduce drinking frequency after relapse, but does not enhance counseling in aiding alcoholic patients to sustain continuous abstinence or delay the resumption of drinking.

Implementation of a regional trauma care system requires a field triage tool that identifies the severely injured patient and transports him to a trauma center, while preserving the flow of minimally injured patients to community hospitals. We prospectively tested the Trauma Score (TS) as a field triage tool and evaluated its accuracy against that of the Injury Severity Score (ISS), calculated after the patients' injuries were fully defined. During an 18-month period, 1106 patients admitted to the trauma center at San Francisco General Hospital had a TS determined in the field (TS1) and on arrival at the emergency department. ⋯ Using an ISS of 20 or more as an indicator of life-threatening injury, we determined the predictive value of TS1. There were 66 false-negatives (ISS, greater than or equal to 20; TS1, 15 or 16) and 107 false-positives (ISS, less than 20; TS1, less than or equal to 14). Using a prehospital TS of 14 or less as an indicator of serious injury, only 20% of a major urban trauma population would qualify for diversion to a trauma center.

To determine if heterosexual activity was a risk factor for acquiring hepatitis B virus (HBV) infection, we studied attendees at a sexually transmitted disease (STD) clinic and students at a large university. Responses to self-administered questionnaires were used to exclude persons with factors known to be related to the acquisition of HBV and to determine the number of recent (past four months) and lifetime sexual partners. Serum samples were tested for hepatitis B surface antigen, antibody to hepatitis B surface antigen, and antibody to hepatitis B core antigen. ⋯ For black heterosexuals in the STD group, no association was found between prevalence of HBV infection and number of recent or lifetime sexual partners. For the heterosexual student group (all white), the prevalence of HBV infection was 1.5% for fewer than three recent partners vs 14% for three or more partners, and 2% for fewer than ten lifetime partners vs 7% for ten or more partners. For white heterosexuals, the risk of acquiring HBV infection increases with increasing amounts of sexual activity and may reach a level similar to that of other groups previously recognized to be at high risk of acquiring hepatitis B.
