EuroQol: health-related quality of life measurement. Valuations of health states by the general public in Norway.

The EuroQol instrument consists of a self administered questionnaire where subjects are asked to value health states on a visual analogue scale. The instrument is playing a role of linking cross-national data in the field of health status measurement. An experiment in Norway with an alternative lay out added little to the feasibility of the instrument. On the other hand, reducing the number of states to be valued did increase the response rate significantly. Valuations in a random sample of Norwegian subjects were quite similar to valuations made by subjects in England, Holland and Sweden. EuroQol valuations may have to undergo a radical transformation before being used as utility weights for life years, but the similarity in valuations across countries is a promising finding in itself. To the extent that these similarities are validated in later studies, authorities in any one of these four countries wishing to use health status indices in medical decision making, may in the future allow themselves to draw on results obtained in any of the other three countries. Particularly for a small country like Norway there is an obvious advantage in this.

Self-rated health and mortality: a review of twenty-seven community studies.

We examine the growing number of studies of survey respondents' global self-ratings of health as predictors of mortality in longitudinal studies of representative community samples. Twenty-seven studies in U.S. and international journals show impressively consistent findings. Global self-rated health is an independent predictor of mortality in nearly all of the studies, despite the inclusion of numerous specific health status indicators and other relevant covariates known to predict mortality. We summarize and review these studies, consider various interpretations which could account for the association, and suggest several approaches to the next stage of research in this field.

Differences in infant mortality rates between Jews and Arabs in Israel, 1975-2000.

BACKGROUND: The infant mortality rate is a health status indicator. OBJECTIVES: To analyze the differences in infant mortality rates between Jews and Arabs in Israel between 1975 and 2000. METHODS: Data were used from the Central Bureau of Statistics and the Department of Mother, Child and Adolescent Health in the Ministry of Health. RESULTS: The IMR in 2000 was 8.6 per 1,000 live births in the Israeli Arab population as compared to 4.0 in the Jewish population. Between 1970 and 2000 the IMR decreased by 78% among Moslems, 82% among Druze, and 88% among Christians, as compared to 79% in the Jewish population. In 2000, in the Arab population, 40% of all infant deaths were caused by congenital malformations and 29% by prematurity, compared to 23% and 53%, respectively, in the Jewish population. Between 1970 and 2000 the rate of congenital malformations declined in both the Arab and Jewish populations. In the 1970s the rate was 1.4 times higher in the Arab community than in the Jewish community, and in 2000 it was 3.7 times higher. CONCLUSION: As in the Jewish population, the IMR in the Arab community has decreased over the years, although it is still much higher than that in the Jewish community. Much remains to be done to reduce the incidence of congenital malformations among Arabs, since this is the main cause of the high IMR in this population.

What is the infant mortality rate in South Africa? The need for improved data.

OBJECTIVE: To review recent infant mortality and birth registration data in South Africa and to investigate geographical differences. OUTCOME MEASURES: Estimates of infant mortality rates, proportion of births not registered, and proportion of births recorded in health services. METHODS: 1. Published infant mortality data for South Africa were collated. Demographic data from national household surveys (1993 and 1994 October Household Surveys and the 1993 Poverty Survey by the Southern African Labour and Development Research Unit (SALDRU) at UCT) were analysed using the indirect method developed by Brass. 2. Birth registration data were analysed and compared with the estimated number of births to identify regions with greater under-registration. The number of births recorded in the health services was analysed by province in order to assess and explore alternatives within health authorities that could complement the existing system. RESULTS: 1. Published estimates of infant mortality for the period from 1990 range from 40 to 71/1,000 births and estimates based on national household surveys conducted in this period from 11 to 81/1,000 births. 2. Completeness of birth registration in the nine provinces ranges from less than 10% in the Eastern Cape, North West and Northern Province to 60% in the Western Cape. An overall improvement from 19% to 60% could be achieved if births recorded through the health services were included in the vital registration system. CONCLUSIONS: The infant mortality rate in South Africa is not known with any certainty. The extent of completeness of the birth registration system was 19%, which indicates a need for urgent improvement in order to provide key health status indicators. This study indicates that there is some potential for improving the extent of birth registration if it could be facilitated through the health service. However, this alone would not achieve complete registration. RECOMMENDATIONS: Surveys will have to be relied upon until such time as routinely available statistics are accurate. The October Household Survey conducted annually by the Central Statistical Service as potentially an important source of health status information. It is imperative that either the design of the birth history questionnaire be improved or that it be replaced by a less frequent but more specialised demographic and health survey.

The importance of distinguishing Hispanic subpopulations in the use of medical care.

Rather than analyzing Hispanics as a homogeneous population, this paper uses the 1977 National Medical Care Expenditure Survey in order to make separate national estimates for Cubans, Puerto Ricans, and Mexicans. Utilization of various health services by these three groups is discussed, as well as their insurance coverage, mean annual expenses by source of payment, and health status indicators. The analysis has a descriptive as well as multivariate component and focuses specifically on the use of physician and hospital services and prescribed medicines. It is found that Puerto Ricans are almost twice as likely as Mexicans, and over four times as likely as Cubans, to be covered by Medicaid; Cubans, on the other hand, are most often privately insured. Of the three groups, Puerto Ricans have the highest annual expenses and are most likely to have at least one physician visit. The number of visits for those with a visit, however, is identical across the groups. The paper discusses the policy implications of these findings, as well as the methodologic implications of classifying various Hispanic subgroups into one all-encompassing category.

Prescribed and over-the-counter medicine use by the ambulatory elderly.

This article examines use of prescription and over-the-counter drugs among a linear probability sample of ambulatory elderly. As previous research has shown, health status indicators are better predictors of use of prescription than nonprescription medications. The analysis suggests that self-medication with over-the-counter drugs may be a first step in illness behavior, rather than a substitute for physician consultation. These preparations are used most frequently for symptoms that the elderly person interprets as nonthreatening; persons concerned about their health are more likely to consult a physician.

Dehydroepiandrosterone-sulfate serum levels and common age-related diseases: results from a cross-sectional Italian study of a general elderly population.

The association of low serum dehydroepiandrosterone sulfate (DHEAS) levels with age, lifestyle, general health status indicators, and specific diseases was investigated in 436 men and 544 women of 65-97 yr old. In both sexes low serum DHEAS levels were associated with age, alcohol intake, number of current medications, and decreased thyroid function. Low DHEAS was also associated with low serum albumin in men and low systolic blood pressure in women. Compared to healthy men (n=106) age-adjusted serum DHEAS levels were significantly lower in men with atrial fibrillation, chronic obstructive lung disease, dementia, parkinsonism, cancer, diabetes, hypothyroidism, and in institutionalized men. Compared to healthy women (n=100) age-adjusted serum DHEAS levels were significantly lower in women with occlusive arterial disease, chronic obstructive lung disease, and osteoporosis. After controlling for differences in lifestyle and general health status parameters, low DHEAS levels remained statistically associated only with atrial fibrillation in men and osteoporosis in women, and it cannot be excluded that these association were spurious, due to multiple comparisons. These data suggest that in elderly people low serum DHEAS levels are more a non-specific indicator of aging and health status than a risk indicator of specific diseases.

Increasing longevity and Medicare expenditures.

Official Medicare projections forecast that the elderly population will be less healthy and more costly over the next century. This prediction stems from the use of age as an indicator of health status: increases in longevity are assumed to increase demand for health care as individuals survive to older and higher-use ages. In this paper I suggest an alternative approach, in which time until death replaces age as the demographic indicator of health status. Increases in longevity are assumed to postpone the higher Medicare use and costs associated with the final decade of life. I contrast the two approaches, using mortality forecasts consistent with recent projections from the U.S. Census Bureau and the Social Security Administration. The time-until-death method yields significantly lower-cost forecasts. The hypothetical cost savings from improved health care small, however, relative to the size of the Medicare solvency problem caused by population aging.

Immigration reform and the health of Latino immigrants in California.

This paper examines Latino immigrant health within the context of the current debate over immigration reform and the resulting cultural construction of public health in California. A review of epidemiologic and ethnographic data indicates that the subordinate socioeconomic status of Latino immigrants plays a major role in both disease etiology and access to health services. However, this status does not explain why certain patterns of health services utilization and disease morbidity and mortality persist although political and economic circumstances have changed. These patterns include the reluctance to utilize certain health services despite access to health insurance and the presence of an epidemiologic paradox in which Latinos have health status indicators comparable to or better than that of other ethnic groups despite high poverty, low education, and lack of access to care. An "economy of culture" model is used to explain these inconsistencies in the political economy model of Latino immigrant health.

Mental distress, economic hardship and expectations of life in Canada among Sudanese newcomers.

As part of a settlement needs assessment of 220 recently arrived Sudanese refugees and immigrants in seven cities, we examined overall health status, indicators of mental distress, economic hardship and expectations of life in Canada. Data were collected in a community-based study using qualitative and quantitative techniques. Results indicate that those Sudanese for whom life in Canada was not what they expected and those who experienced economic hardship as measured by worry over having enough money for food or medicine experienced poorer overall health and reported a greater number of symptoms of psychological distress. After controlling for demographic and related variables, we found that individuals who were experiencing economic hardship were between 2.6 and 3.9 times as likely to experience loss of sleep, constant strain, unhappiness and depression, and bad memories as individuals who do not experience hardship. Healthcare providers should be aware of how postmigration social disadvantages may increase the risk of mental distress particularly among refugees.

The health status of obese individuals in Canada.

OBJECTIVE: To determine whether there is a clinically relevant difference in the health state utilities of obese and non-obese individuals as measured by the Health Utility Index Mark III. METHODS: Secondary analysis of the population-based, cross-sectional, interviewer-administered National Population Health Survey (NPHS), 1996-1997. A probability sample of house-dwelling Canadians, excluding populations on First Nations Reserves, Canadian Armed Forces Bases, the Yukon and Northwest Territories, and long-term residents of hospitals or residential care facilities. The sub-sample used in this analysis consisted of 38 151 respondents (52.4% male) between the ages of 20 and 64 y, excluding pregnant women. Health Utilities Index-Mark III (HUI3) scores were used to define normal weight (body mass index (BMI) 19-24.9 kg/m(2)), overweight (BMI 25-29.9 kg/m(2)), obese (BMI 30-34.9 kg/m(2)), and morbidly obese (BMI> or =35 kg/m(2)) individuals. HUI3 scores were age- and gender-standardized. RESULTS: The overall prevalence of obesity (BMI> or =30 kg/m(2)) in this Canadian population was 13.3%. The average difference in HUI3 scores between normal weight and morbidly obese respondents was 0.04 (P<0.001). Statistically significant (P<0.05) differences across BMI categories were found in each of the eight component attributes of the HUI3. The attributes with the most substantial difference between normal and obese patients were cognition, mobility and pain. All demonstrated a > or =2-fold increase in the proportion of individuals in poorer classifications of health when normal weight respondents were compared with the morbidly obese. The magnitude of the decrement in utility ratings associated with obesity was comparable with other chronic non-cardiovascular conditions such as migraine or colitis. CONCLUSION: The results indicate that changes in self-rated health status appear to be due to significant changes across several relevant domain attributes. Obesity has a significant impact on both quality of life and health.

Health status, community integration, and economic risk factors for mortality after spinal cord injury.

OBJECTIVE: To examine the association of health, community integration, and economic status with subsequent mortality and life expectancy among persons with spinal cord injury. DESIGN: Cohort study. SETTING: Model Spinal Cord Injury Systems (MSCIS) hospitals. PARTICIPANTS: A total of 5947 persons injured since 1973 who were enrolled in the National Spinal Cord Injury Database and who were still alive and received an annual evaluation from November 1995 through March 2002. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Mortality was determined by routine follow-up supplemented by information from the Social Security Death Index. A logistic regression model based on the full set of predictor variables was developed to estimate the chance of dying in any given year. RESULTS: After adjusting for demographic characteristics and injury severity, health status indicators, measures of community integration, and economic status indicators all had relatively small but statistically significant effects (20%-70% increases) on the likelihood of dying during the next year. Inclusion of these factors may result in higher life expectancy estimates under highly favorable conditions. CONCLUSIONS: Whereas previous reports of the MSCIS data have identified the life expectancies associated with a particular set of demographic (eg, age, gender) and injury-related characteristics (level and completeness of injury; ventilator dependence), the current analysis suggests that consideration of health, economic, and psychosocial factors may make computations of life expectancy more accurate.

Risk factors for serious fall related injury in elderly women living at home.

OBJECTIVES: To study whether balance, function, and other health status indicators can predict serious fall related injury in elderly women living at home. METHODS: In this prospective study, the authors took a random sample of 307 women aged 75 years and over (mean 80.8 years, response rate 74.5%), living in the community. Serious fall injuries which occurred over a period of during one year were recorded, together with baseline registrations of health, function, and tests of walking and balance. RESULTS: In all, 155 women (50.5%) fell one or more times. One hundred and fifty six (51%) of the 308 falls resulted in a fall related injury, 74 (24%) in a serious fall related injury, and 40 falls (13%) resulted in fractures. The presence of rheumatic disorders, inability to rise from the floor, arthrosis of the hip, having had more than one fall during the one year follow up period, and an increased tendency to sway in the frontal plane when doing a calculation task were independent and significant predictors for serious fall related injury (fractures included). The independent predictors of fall induced fractures were experiencing more than one fall in the follow up period, cognitive impairment, and receiving care from professional or other. CONCLUSION: The study suggests that rheumatic disorders and the inability to get up from lying on the floor were the strongest independent risk factors for serious fall related injury. Experiencing more than one fall in the follow up period and cognitive impairment are the strongest independent predictors for fall induced fractures. Age was not a significant predictor of serious fall related injury. Assessment of these markers is feasible in a clinical setting and is a useful way of identifying those who are at risk of serious fall related injuries.

A practical tool for community-oriented primary care community diagnosis using a personal computer.

BACKGROUND AND OBJECTIVES: Community-oriented primary care (COPC) is considered an attractive concept by many but has had limited implementation due to a lack of practical methodology. An important step in COPC is assessment of a community's health status, using health indicators as one means of assessment. Currently, there is no easy way to combine these indicators and examine their distribution over a community. This study analyzed a process for doing that by using a personal computer. METHODS: For the community studied, all available community-based health indicators were identified. A process for combining these indicators, using commonly available database and spreadsheet software, was developed and analyzed for cost, clinical utility, and problems encountered. RESULTS: Problems were encountered with collecting and combining some data, but a clinically useful tool was produced. Costs, including purchase of all software (with mapping software), were $1,500-$2,000. CONCLUSIONS: With efforts to reduce the initial costs, this is a practical and clinically useful tool for viewing the geographic distribution of community health indicators. Such practical methodology is essential for COPC development.

Comparing alternative methods for composing community peer groups: a data warehouse application.

A method for assessing the health status of communities has been under development for a decade at the University of South Florida. Known as CATCH (Comprehensive Assessment for Tracking Community Health), the method utilizes health status indicators from multiple data sources. With federal grant support, a unique data warehouse has been created to automate CATCH assessments and to enhance online analytical processing for efficient data browsing, knowledge discovery, and model testing. A comparison of two peer grouping methods (population size versus predicted age-adjusted mortality) is reviewed to demonstrate the warehouse capabilities.

Socio-demographic factors and self-reported functional status: the significance of social support.

BACKGROUND: The aim of the present work was to investigate the relative importance of socio-demographic and physical health status factors for subjective functioning, as well as to examine the role of social support. METHODS: A cross-sectional health survey was carried out in a Greek municipality. 1356 adults of the general population were included in the study. Personal interviews were conducted with house-to-house visits. The response rate was 91.2%. Functioning has been measured by five indexes: 'The Social Roles and Mobility' scale (SORM), 'The Self-Care Restrictions' scale (SCR), 'The Serious Limitations' scale (SL), 'The Minor Self-care Limitations' scale (MSCR) and 'The Minor Limitations in Social Roles and Mobility' scale (MSORM). RESULTS: Among the two sets of independent variables, the socio-demographic ones had significant influence on the functional status, except for MSORM. Allowing for these variables, the physical health status indicators had also significant effects on all functioning scales. Living arrangements and marital status had significant effects on four out of five indexes, while arthritis, Parkinson's disease, past stroke and kidney stones had significant effects on the SCR and SL scales. CONCLUSIONS: These results suggest that socio-demographic factors are as important as physical health variables in affecting a person's ability to function normally in their everyday life. Social support appears to play a significant role in explaining differences in subjective functioning: people living alone or only with the spouse, particularly the elderly, seem to be in greater risk for disability problems and should be targeted by preventive programs in the community.

Method for the classification of countries according to health-related indicators.

A taxonomic approach using cluster analysis and principal component analysis has grouped the countries of the world in eight clusters, in an initial attempt to propose a worldwide spatial classification based on the following health-related indicators: (a) those directly related to the health status of the population; (b) those measuring the provision of health care; (c) those linked to population characteristics; and (d) those reflecting economic parameters. The cartographic representation was based on demographic maps which display the area of each country in proportion to its population size.

Assessing the construct validity of the Italian version of the EQ-5D: preliminary results from a cross-sectional study in North Italy.

BACKGROUND: Information on health related quality of life (HR-QOL) can be integrated with other classical health status indicators and be used to assist policy makers in resource allocation decisions. For this reason instruments such as the SF-12 and EQ-5D have been widely proposed as assessment tools to monitor changes in HR-QOL in general populations and very recently in general practice settings as well AIM: The primary goal of our study was to assess the construct validity of the Italian version of the EQ-5D in a general population of North Italy using socio-demographic factors and diagnostic sub-groups. Our secondary goal was to assess the concurrent validity of the EQ-5D and SF-12. METHODS: The SF-12, the EQ-5D plus an additional questionnaire on socio-demographic characteristics, clinical conditions and symptoms were completed by 1,622 adults, randomly selected from the Registry of the Health Authorities of the city of Bologna, Italy. The primary care physician of each subject was contacted to report on the subject's health status. RESULTS: Our findings indicate that the Italian version of the EQ-5D is well accepted by the general population (91% response rate), has good reliability (Cronbach's alpha 0.73), and shows evidence of construct validity. CONCLUSION: Our data provide a basis for further research to be conducted to assess the validity of the EQ-5D in Italy. In particular future studies should focus on assessing its ability to detect a clinically important change in health related quality of life over time (responsiveness).
