Differential mortality in New York City (1988-1992). Part Two: excess mortality in the south Bronx.
(17/4576)
To display the extent of variations in mortality according to geographic regions in New York City, we have compared mortality in New York City as a whole with that of the South Bronx. Mortality records for 1988 to 1992 and 1990 US census data for New York City were linked. The 471,000 residents of the South Bronx were younger, less educated, and more likely to lack health insurance than other New Yorkers. Using age- and gender-stratified populations and mortality in New York City as standards, age-adjusted death rates and excess mortality in the South Bronx were determined. All-cause mortality in the South Bronx was 26% higher than the city as a whole. Mortality for AIDS, injury and poisoning, drug and alcohol abuse, and cardiovascular diseases were 50% to 100% higher in the South Bronx than in New York City; years of potential life lost before age 65 in the South Bronx were 41.6% and 44.2% higher for men and women, respectively, than in New York City; AIDS accounted for the largest single share of excess premature deaths (21.8%). In summary, inequalities in health status, reflected by higher mortality rates in the South Bronx, are consistent with, and perhaps caused by, lower socioeconomic status and deficient medical care among residents of this inner-city community.

Referrals for coronary angiography in a high risk population.
(18/4576)
OBJECTIVES: To examine variations in referral for coronary angiography within Northern Ireland and relate these to local death rates from coronary artery disease (ICD rubrics 410-414). DESIGN: A descriptive retrospective analysis of aggregate hospital activity data for 1979-88 and corresponding mortality rates in the local population. SETTING: Two regional referral hospitals and 26 local district council areas. PATIENTS: 5173 patients aged 35-74 years with an underlying diagnosis of ischaemic heart disease, whose records contained complete information on their age, sex, and home address. MAIN MEASURES: Age-standardised angiography rates and corresponding standardised death rates derived from the registrar general's reports. RESULTS: Among the 26 constituent district council areas there was significant heterogeneity in the angiography rates, ranging from 62 to 335/100,000 in men and from 7 to 62/100,000 in women (likelihood ratio statistic 856 and 359 respectively). There was no significant association between these angiography rates and the local death rates from ischaemic heart disease. CONCLUSION: The results suggest a non-uniform threshold for referral for angiography. IMPLICATIONS: Clinicians need to examine the appropriate indications for referral for invasive investigation.

Is antenatal care effective in reducing maternal morbidity and mortality?
(19/4576)
Women in developing countries are dying from simple preventable conditions but what impact can the procedures collectively called antenatal care having in reducing maternal mortality and morbidity? More importantly what is antenatal care? This review found that questions have been raised about the impact of antenatal care (specifically on maternal mortality) since its inception in developed countries, and that although the questions continue to be asked there is very little research trying to find answers. Many antenatal procedures are essentially screening tests yet it was found that there were very few results showing sensitivity and specificity, and that they rarely complied with the established criteria for the effectiveness of a screening test. The acknowledged gold standard measurement of effectiveness is the randomized controlled trial, yet the only results available referred to nutritional supplementation. This service of flawed methodology has been exported to developing countries and is being promoted by WHO and other agencies. This paper argues that there is insufficient evidence to reach a firm decision about the effectiveness of antenatal care, yet there is sufficient evidence to cast doubt on the possible effect of antenatal care. Research is urgently required in order to identify those procedures which ought to be included in the antenatal process. In the final analysis the greatest impact will be achieved by developing a domiciliary midwifery service supported by appropriate local efficient obstetric services. That this domiciliary service should provide care for women in pregnancy is not disputed but the specific nature of this care needs considerable clarification. (+info)
Studies of avoidable factors influencing death: a call for explicit criteria.
(20/4576)
OBJECTIVE: To analyse studies evaluating cases of potentially "avoidable" death. DESIGN: The definitions, sources of information, and methods were reviewed with a structured protocol. The different types of avoidable factors,--that is, deficiencies in medical care that may have contributed to death--were categorised. The presence of explicit classifications and standards was examined. basic criteria for quality of the studies were defined and the numbers of studies fulfilling these criteria were assessed. SETTING AND PARTICIPANTS: 65 studies, published during 1988-93 in peer reviewed medical journal for which the title, or abstract, or both indicated that they had analysed potentially avoidable factors influencing death. Studies analysing aggregated data only, were not included. RESULTS: Only one third of the studies fulfilled basic quality criteria,--namely, that the avoidable factors examined should be defined and the sources of information and people responsible for the judgements presented. The definitions used comprised two levels, one stating that there had been errors in management (process) and the other that the errors may have contributed to the deaths (outcome). Only 15% of the studies explicitly defined what type of factors they had looked for and 8% referred to specified standards of care. CONCLUSIONS: Studies of avoidable factors influencing death may have considerable potential as part of a system of improving medical care and reducing avoidable mortality. At present, however, the results from different studies are not comparable, due to differences in materials and methods. There is a need to improve the quality of the studies and to define standardised explicit definitions and classifications. (+info)
Health status during the transition in Central and Eastern Europe: development in reverse?
(21/4576)
This paper reports on a study of the cross-national trends in health status during the economic transition and associated health sector reforms in Central and Eastern Europe (CEE). The central premise is that before long-run gains in health status are realized, the transition towards a market economy and adoption of democratic forms of government should lead to short-run deterioration as a result of: (i) reduction in real income and widening income disparities; (ii) stress and stress-related behaviour; (iii) lax regulation of environmental and occupational risks; and (iv) breakdown in basic health services. Analysis focused on three broad indicators of health status: life expectancy at birth, infant mortality rate and the probability of dying between the ages of 15 and 65 years, shown by the notation '50q15'. The study revealed significant new information about health status and the health sector which could not have been obtained without a proper cross-national study. Infant mortality rates in former socialist economies (FSE) follow the global trend, declining as per capita income rises. However, rates are lower than would be predicted given their income levels. Despite declining infant mortality, life expectancy at birth in the former socialist economies decreases as per capita income rises, in marked contrast to global trends. This is because rising income level is associated with greater probability of death between the ages of 15 and 65: the wealthier the society, the less healthy is its population, particularly for its males. Causes of death in the FSE follow global trends: higher death rates due to infectious and parasitic diseases in poorer countries, and higher death rates due to chronic diseases in wealthier countries. However, age-standardized death rates for chronic diseases generally associated with unhealthy lifestyles and environmental risk factors are very high when compared with wealthier established market economies (EME). Policies and procedures which alter the effectiveness of health services have had a demonstrable but mixed impact on health status during the early phase of transition. Effective preventive health strategies must be formulated and implemented to reverse the adverse trends observed in Central and Eastern Europe. (+info)
An approach to an index of hospital performance.
(22/4576)
Two indexes are described, based on measures of administrative effectiveness and patient care effectiveness. The measures used were selected and ranked by a Delphi panel from a list of 30 measures drawn from the literature. Weights were assigned by the panel to 19 selected measures. The resulting indexes did well in a test on data collected from 32 Texas hospitals. (+info)
Mortality among homeless shelter residents in New York City.
(23/4576)
OBJECTIVES: This study examined the rates and predictors of mortality among sheltered homeless men and women in New York City. METHODS: Identifying data on a representative sample of shelter residents surveyed in 1987 were matched against national mortality records for 1987 through 1994. Standardized mortality ratios were computed to compare death rates among homeless people with those of the general US and New York City populations. Logistic regression analysis was used to examine predictors of mortality within the homeless sample. RESULTS: Age-adjusted death rates of homeless men and women were 4 times those of the general US population and 2 to 3 times those of the general population of New York City. Among homeless men, prior use of injectable drugs, incarceration, and chronic homelessness increased the likelihood of death. CONCLUSIONS: For homeless shelter users, chronic homelessness itself compounds the high risk of death associated with disease/disability and intravenous drug use. Interventions must address not only the health conditions of the homeless but also the societal conditions that perpetuate homelessness. (+info)
Explaining educational differences in mortality: the role of behavioral and material factors.
(24/4576)
OBJECTIVES: This study examined the role of behavioral and material factors in explaining educational differences in all-cause mortality, taking into account the overlap between both types of factors. METHODS: Prospective data were used on 15,451 participants in a Dutch longitudinal study. Relative hazards of all-cause mortality by educational level were calculated before and after adjustment for behavioral factors (alcohol intake, smoking, body mass index, physical activity, dietary habits) and material factors (financial problems, neighborhood conditions, housing conditions, crowding, employment status, a proxy of income). RESULTS: Mortality was higher in lower educational groups. Four behavioral factors (alcohol, smoking, body mass index, physical activity) and 3 material factors (financial problems, employment status, income proxy) explained part of the educational differences in mortality. With the overlap between both types of factors accounted for, material factors were more important than behavioral factors in explaining mortality differences by educational level. CONCLUSIONS: The association between educational level and mortality can be largely explained by material factors. Thus, improving the material situation of people might substantially reduce educational differences in mortality. (+info)
