Racial differences in the incidence of hypertensive end-stage renal disease (ESRD) are not entirely explained by differences in the prevalence of hypertension.

Blacks experience a disproportionate risk of end-stage renal disease (ESRD) compared with whites. The increased prevalence of hypertension in blacks has been suggested as an explanation for this increased risk. We were able to examine this possibility using hypertensive ESRD incidence rates in a population with well-characterized prevalence of hypertension and rate of its control. After adjusting rates of hypertensive ESRD for age, sex, and differences in the prevalence of hypertension by race, we found black:white (B:W) relative risk still to be increased. Prevalence estimates for moderate-severe hypertension and differences in the control of hypertension between the two race groups are of insufficient magnitude to explain the increase in adjusted relative risk. This observation provides further support for the possibility that there are racial differences in the susceptibility to renal damage from elevated BP, which may explain increased risk for hypertensive ESRD in blacks, or that hypertension is being erroneously diagnosed as the cause of ESRD in blacks when another cause is present.

Isolated systolic hypertension: declining prevalence in the elderly.

Isolated systolic hypertension is a prevalent condition among elderly U.S. residents of all age, sex, and race groups. In a population-based survey conducted on 4,672 adult residents of Georgia in 1981, prevalence rates were considerably below those noted in earlier surveys, such as Baldwin County, Georgia (1962), National Health Examination Series I (1960-1962), Evans County, Georgia (1967-1969), National Health and Nutrition Examination Survey I (1971-1974) and/or II (1976-1980). The lower 1981 prevalence of isolated systolic hypertension in Georgia was observed in association with a much greater likelihood of anti-hypertensive therapy in adult and elderly patients. The overall trend for early and more aggressive therapy of diastolic hypertension might account for less arterial rigidity and occurrence of isolated systolic hypertension in later life.

The physician and patient education: a review.

Education is an essential part of medical care and must be conducted properly for the patient to receive optimal benefit. Since physicians are responsible for a major portion of the health care delivered, there is a need to understand how patient education is used by these practitioners. Our current understanding of physician-patient education practices is reviewed in this paper. The frequency of patient education by physicians, the educational content and processes employed, and physician attitudes toward patient education are examined. This analysis shows that patient education is a salient issue among physicians. They report a high frequency of use of patient education with as many as 20% of visits containing a major educational intervention. The content of these interventions is weighed heavily toward instructions and information, with little assessment, monitoring or reinforcement noted. Physician attitudes toward patient education reflect an awareness of its importance and insecurity with actual educational interventions. A number of substantive issues remain to be addressed, including interventions to improve physician educational practice.
