Mortality experience in relation to a measured arsenic trioxide exposure.

This report examines the mortality experience of 527 men who retired from a copper smelter where they were exposed to airborne arsenic trioxide. Urinary arsenic values of all plant employees were determined in 1973, and the relative arsenic exposure in the various departments of the plant were determined. The relationship of airborne arsenic concentrations to urinary arsenic values was studied in a separate experiment, and the feasibility of using urinary arsenic values as a measure of arsenic exposure was established. The mortality experience of the cohort under study showed them to have a mortality 12.2% higher than was found for males of the same area at the same ages and in the same time period. The excess mortality was due chiefly to respiratory cancer. When the deaths were classified by total lifetime arsenic exposure, the respiratory cancer mortality was linearly related to the amount of exposure. The 1973 figures for arsenic exposure underestimated the exposure of the cohort group by a factor of possibly 10. Evidence was obtained which suggests that after removal from arsenic exposure, the risk of lung cancer declines. Certain of the data which are presented suggests there may be a threshold value for airborne arsenic trioxide exposure below which no adverse effects may be expected.

The health of retired fibrous glass workers.

A total of 416 men, retiring during the period 1945 to 1972 from six plants engaged mainly in the manufacture of fibrous glass insulation, were studied to see how their mortality experience compared with that of white men in the entire United States living in comparable age and time intervals. The mean follow-up period from first exposure was about 30 years. Overall mortality was low and there was no evidence of an excess in respiratory cancer mortality. No mesotheliomas were noted. For 115 men retiring from the same six plants during the period 1945 to 1972 due to a disability the distribution of disabilities by cause was compared with an expected distribution based on the experience of the Social Security Administration. This comparison showed no evidence of any unusual health hazards among fibrous glass workers, except a possible excess in chronic bronchitis.

Physician's working hours and patients seen before and after national health insurance: "free" medical care and medical practice.

Surveys were made of a sample of physicians before and after the introduction of a national health insurance plan in Montreal, Canada. Although the number of physicians in active practice seemed unaffected by the plan, their average working day was reduced 1.5 hours. Declines ranged from 0.3 hours for general internists to 2.7 hours for general surgeons. The average daily volume of services by physicians in the area also declined because of a decline in telephone consultations, and home and hospital visits. Office visits increased sharply. Changes in the type of services were clearly related to the fee schedule adopted by the government, with large declines in services for which payment was probably inadequate in relation to physician's time required. If the fee schedule reflected actual collections prior to the health insurance plan, then gross physician income increased as the result of redirecting services to better paying activities.

Implications for nursing in the library activities of the Regional Medical Programs.

A consideration of federal support of library facilities, resources and services provided through Regional Medical Programs and the National Library of Medicine's Extramural Programs as they relate to nursing is presented. The position of nurses in policy making and their limited role in the programs are noted. Suggestions are made for greater nursing involvement. It is strongly advised that nurses make greater use of library resources and that administrators and staffs of libraries be more concerned with meeting their needs.
