Women's preferences for gynecological examiners: sex versus role.

Preferences for gynecological examiners are studied in a cervical cancer screening program. Sex appears to be a more important factor in preference than the professional level of the examiner. Female health professionals were preferred by a majority of patients; the distinction between physicians and nurse practitioners was a much less important factor. Female examiners were particularly important to low-income and Mexican-American participants, and to women who were reluctant to participate in screening programs.

Hypertension-related mortality in California.

Death rates in California for hypertension-related diseases during 1969-71 and 1979-81 are compared. During both periods, age-standardized rates for a composite hypertension-related mortality category are highest for blacks, followed by whites, and lowest for Asians and Pacific Islanders. Filipinos who have high prevalence rates of hypertension record low rates of hypertension-related mortality. After adjusting for the comparability ratio, the age-standardized hypertension-related death rate declined by more than 28 percent between 1969-71 and 1979-81. The decrease was greatest at age 15-44 years. Of all major hypertension-related diseases, cerebrovascular diseases registered consistently large percentage declines in mortality for all age and race groupings examined. Possible reasons for the considerable decline in hypertension-related mortality and low death rates for Asians and Pacific Islanders are discussed. The combined effects of improved population awareness, level of treatment, and control of hypertension; a greater knowledge of cardiovascular risk factors and associated modifications of behavior; and improved medical technology and care may have contributed to the decline.

Platelet utilization in a university hospital.

Two hundred forty-three patients received 22,717 U of platelets in our hospital during a three-month period. Those with hematologic diseases accounted for 43% of the patients but used 86% of the platelets. Sixty-eight percent of the transfusions were given to prevent bleeding and 32% were given to treat active bleeding. Ninety-two percent of therapeutic transfusions but only 22% of prophylactic transfusions met guidelines established by the Transfusion Therapeutics Committee of the University of Minnesota Hospital and Clinics, Minneapolis. However, 78% of prophylactic platelet transfusions that did not meet the guidelines involved patients with at least one clinical factor that their physicians believed placed them at an increased risk of bleeding. Following this analysis, the guidelines were modified and applied prospectively to requests for platelets. This resulted in a 14% decrease in the number of platelet units used during the following year. We conclude that published recommendations for platelet transfusions do not reflect the complex nature of many patients' conditions and that the use of guidelines developed by the medical staff can alter the use of platelet transfusions.
