A comparison of three health status indicators.

Interest in health status indicators has produced measures of widely varying applicability. We were interested in the use of such indices to establish mean recovery curves for groups of similar patients undergoing acute hospital treatment. A longitudinal study relating resource usage to these recovery curves had been intended but there were difficulties in finding suitable indicators. Firstly, two published indicators relying on patient interviews were tested for consistency. Poor correlations were found among those scorers unfamiliar with the patients and it seems unlikely that these indicators could be used in a routine system. Different parts of the indices presented difficulties to the different professions involved in scoring, and a multidisciplinary approach may be needed in assessing full health. The indicators tested included no assessment of prognosis. Those parts of the indices which had produced significant correlations were retained in subsequent work and were supplemented by further measures designed to overcome the earlier difficulties. A new trial of this indicator was undertaken where staff, familiar with the patients, scored data recorded by the Problem Oriented Medical Record system. This produced improved correlations but some problems remain.

Health status indices and access to medical care.

This paper examines the uses of some health status indices in measuring equity of access to medical care. Empirical examples are provided using data from national surveys of the U.S. population conducted from 1964 through 1976. A simple indicator, mean number of physician visits, suggests that between 1963 and 1976 the poor improved their position relative to the rest of the population and, indeed, currently enjoy the highest level of access. However, a second measure, the use-disability ratio indicates that the poor may still receive less care relative to their need. A third measure, the symptoms-response ratio suggests how norms of appropriate behavior might be incorporated into an access measure.

The President's NHI proposal: solution or problem?

Are the Carter administration's NHI principles appropriate for resolving health problems in the United States? An examination of the applicability of these principles to the problems--categorized in terms of health status indicators, health care resources, and consumer satisfaction--concludes that evidence in these areas does not indicate a need for NHI. Recommendations for establishing appropriate health care proposals follow.

Indicators of health status in adolescence.

The study reported here is based on data obtained in 1968-1970 from a representative community sample of urban black youths in the United States aged 12-17 years, inclusive. Analysis is directed at conceptual and methodological issues in measureing health status. It suggests the need for greater attention to subjective self-evaluated self-reported components of health status, specified here as "ontological" health. This is related to health and illness behavior generally, to utilization of health services more particularly. The case is made for a multiple-indicator approach to measuring health status as being more consistent with the multidimensional phenomenon to which it refers. The method used in this study for deriving a composite health status index from four component self-reported indicators is described. The distribution of the sample on this composite was used to identify self-reported health conditions that warrant attention from providers of adolescent health services. Since subjective evaluations influence experienced severity of health problems, the health status composite index was applied in this study as a means of discriminating differntial seriousness in self-reported health problems. Finally, some differences between indications of "ontological" health and "medical" health also are analyzed for commonalities and differences between them.

Sociocultural barriers to medical care among Mexican Americans in Texas: a summary report of research conducted by the Southwest Medical Sociology Ad Hoc Committee.

This paper summarizes research findings from members of the Southwest Medical Sociology Ad Hoc Committee concerning sociocultural barriers to medical care among Mexican Americans in Texas. Committee members individually, or in two-person groups, studied a number of factors concerning Mexican-American medical care in Texas such as: 1) mortality, morbidity, and other health status indicators; 2) health manpower and educational needs; 3) political factors impeding economical health care; 4) alienation, familism, and their relationship to utilization of the health services; 5) language and communication barriers; and 6) folk medicine. Findings include documentation that structural alienation of Mexican-Americans from mainstream Anglo-American middle-class society is carried over into their relation with utilization of the health care delivery system; that their emphasis on familism works alternatively to encourage and discourage their seeking access to health care; the language differences serve to perpetuate certain cultural differences that are inimical to health care delivery; and that curanderismo can be seen as complementing other types of health care. The report concludes with a number of recommendations for accomplishing cultural integration that will lead to better care for this segment of the health population.

A classification of sociomedical health indicators: perspectives for health administrators and health planners.

The conceptualization and operationalization of measures of health status are considered. Health indicators are conceived as a subset of social indicators, and therefore, as any social indicator, they are viewed as derivative from social issues. The interrelationships of different frames of reference for defining and measuring health that have accompained three distinct health problem patterns in the United States are viewed from a developmental perspective. Mortality and morbidity rates, the traditional health indicators, by themselves no longer serve to assess health status in developed nations. Their deficiencies as indicators serve as background for a classification schema for sociomedical health status indicators that relates health definition frames of reference, measures of health status, and health problems. The role of a group of health indicators-sociomedical heath indicators-in the current formulation of health status measures is assessed.

Classification

A new planning methodology to assess the impact of the health care system on health status.

This article summarizes a new methodology recently developed by the Rand Corporation which permits health planners to assess the impact of the local health care system on the health status of the population. The methodology, in algorithm form, should assist health planners in developing objectives and actions related to the occurrence of selected health status indicators and should be amenable to health care interventions. Emphasis has been placed on developing a simplified, approximate analysis that health planners will find both feasible and effective. No detailed mathematic analyses are called for. The data required are, in most instances, readily obtainable. The algorithm is a methodology by which HSAs can investigate determinants of health status, identify breakdowns in the health care system, and specify needed improvements in the system. The goal of these algorithms is to assist HSAs to obtain valid and sufficiently detailed data that will provide a basis for monitoring breakdowns in the health care system and to improve planning decisions aimed at preventing such breakdowns. This should, in turn, affect population health status in the planning area.

Ongoing assessment of health status in patients with diabetes mellitus.

In 1990, the Division of Endocrinology and Metabolism of Henry Ford Hospital established an Outcomes Management data base for patients with Type I and Type II diabetes. A first cohort of 117 patients completed a baseline and 6-month follow-up assessment; a second cohort of 116 patients completed the baseline assessment. Assessment at each time point includes: the Short Form--36 Questions (SF-36) health status instrument; a set of clinical variables known as the Diabetes TyPE scale Form 2.2 abstracted from the medical record; and the physicians' ratings of patient's health status along the major dimensions of the SF-36. Success with both face-to-face and mailed administration of the SF-36 has been good, with response rates of over 85% using both methods. Comparison of patient and physician ratings of patient health status indicated a significant discrepancy on ratings of general health status, with physicians' ratings higher than those of patients themselves. "Tight" glycemic control (as measured by glycosylated hemoglobin) was associated with somewhat lower ratings on the various SF-36 dimensions for all patients in the first cohort and for Type I patients in the second cohort. However, this effect did not seem to be attributable to those features of a complex regimen used to achieve tight control, but rather reflected a complex combination of age, education level, and number of daily injections associated with achieving good control.

Relationship between work environment and anamnestic health status. Use of predictors, indicators and indices for the evaluation of medical and environmental factors.

Experience with computerized medical record systems in handling medical data in hospital and health screening environments has led to the development of a new approach to the evaluation of medical data. Predictors and indicators quantify the "information value" of medical data and can, theoretically, do so for all types of data. This paper describes the methodology and presents the results obtained when the technique was applied to the anamnestic data of the medical history and environmental data about the conditions in the work environment. Over 4,000 individuals who underwent multiphasic health screening were used as a data base for this study. From these 4,000 persons 3,164 were used for the calculation of anamnestic predictors and indicators and 1,013 for the environmental predictors and indicators. Anamnestic environmental indices were calculated upon 77 test individuals so as to correlate the association and dependence of the two indices.
