[Comparability of the data presented in the medical death certificate and the death rate statistics index].

It having been impossible to use the Death Rate Statistics Index for analyzing the death rate in the city of Seville for 1985 and this Index having been substituted by the Medical Death Certificate has lead us to carry out this study to compare the data reflected in these two documents and determine the extent to which the Medical Death Certificate conforms to the Death Rate Statistics Index, used officially, and its validity. The results show that both documents tally to a great degree, the DRSI providing somewhat more information with regard to the process leading up to the deaths, this having led us to decide to make the death rate analysis for 1985 in Seville by using the Medical Death Certificate as the document on which the information will be based.

Comments on HCFA hospital death rate statistical outliers. Health Care Financing Administration.

In March 1986, the Health Care Financing Administration (HCFA) released ten lists of death-rate "outlier" hospitals, one for all 1984 Medicare discharges and nine for specific DRGs. Recent Medicare hospital discharge abstracts have substantially undercounted in-hospital deaths, with large variations by state. Apart from the proportion of a hospital's cases in 80 DRGs, the predictive models had no measures of case severity based on diagnosis or procedure. Having DRG 123 (all deaths from acute myocardial infarction) as an independent variable in the all-death regression model probably accounted for much of its high r2. Inclusion of an independent variable for average length of stay (ALOS) favored hospitals in higher ALOS states by higher predicted death rates. Model bias also favored lower-risk hospitals. Small numbers of predicted deaths for specific DRGs limited low-volume hospitals on these outlier lists to those with high ratios of actual to predicted deaths. On six of the nine DRG-specific outlier lists, a total 1,222 hospitals had unfavorable residuals, while only 8 were favorable. Ten recommendations are given to increase reliability of future outcome analyses.

Continuing importance of nitrate contamination of groundwater and wells in rural areas.

The contamination of groundwater and rural drinking water supplies by nitrates from livestock and human excrement, other organic waste, or chemical fertilizers is a potential hazard throughout the world. Infant illness and death from nitrate-induced methemoglobinemia is probably often misdiagnosed, perhaps as sudden infant death syndrome, and certainly contributes to the national infant death rate statistics. A 1950 report listed 144 cases of infant methemoglobinemia with 14 deaths in one 30-month period in Minnesota. Infant deaths resulting from misdiagnosis of this preventable, treatable intoxication were still occurring as recently as 1986 in South Dakota. In this state, about 39% of dug or bored wells were unsafe due to high nitrate content, compared with 22% of drilled wells and 16% of driven wells. Properly constructed wells more than 30 m deep are more likely to be safe. Groundwater concentrations of nitrate may be unsafe for consumption, and standards are needed to regulate such contamination. Such standards could serve as guidelines and could be enforceable in the case of water systems dependent on wells.

Belfast children's awareness of violent death.

Although violent deaths due to the Northern Ireland civil strife receive wide publicity, up to three times as many people are killed in road accidents, and death-rate statistics reveal that natural causes predominate. Against this backdrop the study explores development of the death concept in Belfast children (n = 200). A disguised test technique was supplemented by more probing questions. Subject variables were age (five groups from 3 years 8 months to 15 years 8 months), sex, verbal ability, religious denomination, and place of residence. Vocabulary scores were significantly related to conceptual level for the 7- and 13-year-olds only. More advanced definitions were given by the 4-year-olds living in the 'troubled' areas, by both groups of 13-year-old Protestants and by the 15-year-old Protestants living in the 'less troubled' areas. Overall, the children attributed death more often to sickness than to accidents or to violence; just as frequently to heart disease and to old age as to explosions and shootings and more often to road accidents and to cancer than to specific local violence. These attributions quite accurately reflect the total objective situation, and suggest that violence is not a salient dimension for the children of the area.

[Respiratory tuberculosis mortality in the health region of the Valencia community (1976-1980].

Respiratory tuberculosis continues to be a health and social problem in Spain. The data for carrying out this study was obtained from the Monographic Health Studies: death rate statistics, published by the Regional Government of Valencia for the 1976-1980 five-year period. In this study, the standardized death rates and the standardized causes thereof, with regard to respiratory tuberculosis have been calculated using direct method. In addition, the distribution of tuberculosis has been broken down according to age and sex using specific rates and statistical tests to compare proportions. The results obtained make it possible to compare the different Health Care Areas with regard to the Region of Valencia, it being established that Areas 2, 5, 9-12 and 21 are those revealing an overly high death rate due to respiratory tuberculosis. Likewise, the predominance of this cause of death among men and among the groups most up in age must be stressed, due to the importance of this disease in the working environment and diverse socioeconomic factors.

Effect of interferon gamma on infection-related death in patients with severe injuries. A randomized, double-blind, placebo-controlled trial.

OBJECTIVE: To assess the efficacy of interferon gamma in reducing infection and death in patients sustaining severe injury. DESIGN: Multicenter, randomized, double-blind, placebo-controlled trial with observation for 60 days and until discharge for patients with major infection on day 60. SETTING: Nine university-affiliated level 1 trauma centers. PATIENTS: Four hundred sixteen patients with severe injuries, assessed by Injury Severity Score and degree of contamination. INTERVENTION: Recombinant human interferon gamma, 100 micrograms, was administered subcutaneously once daily for 21 days (or until patient discharge if prior to 21 days) as an adjunct to standard antibiotic and supportive therapy. MAIN OUTCOME MEASURES: Incidence of major infection, death related to infection, and death. RESULTS: Infection rates were similar in both treatment groups; however, patients treated with interferon gamma experienced fewer deaths related to infection (seven [3%] vs 18 [9%]; P = .008) and fewer overall deaths (21 [10%] vs 30 [14%]; P = .17). While 12 early deaths (days 1 through 7) occurred in each treatment group, late death occurred in 18 placebo-treated patients and nine in interferon gamma-treated patients. The results were dominated by findings at one center, which had the highest enrollment and higher infection and death rates. Statistical analysis did not eliminate the possibility of an unidentified imbalance between arms as an explanation for the results. CONCLUSION: Further evaluation is required to determine the validity of the observed reduction in infection-related deaths in patients treated with interferon gamma.

Mortality among unionized construction plasterers and cement masons.

BACKGROUND: Plasterers perform a variety of duties including interior and exterior plastering of drywall, cement, stucco, and stone imitation; the preparation, installation, and repair of all interior and exterior insulation systems; and the fireproofing of steel beams and columns. Some of the current potential toxic exposures among plasterers include plaster of Paris, silica, fiberglass, talc, and 1,1,1-trichloroethylene; asbestos had been used by the plasterers in the past. Cement masons, on the other hand, are involved in concrete construction of buildings, bridges, curbs and gutters, sidewalks, highways, streets and roads, floors and pavements and the finishing of same, when necessary, by sandblasting or any other method. Exposures include cement dust, silica, asphalt, and various solvents. METHODS: Proportionate mortality ratios (PMRs) and proportionate cancer mortality ratios (PCMRs) were calculated for 99 causes of death among 12,873 members of the Operative Plasterers' and Cement Masons' International Association who died between 1972 and 1996 using United States age-, race-, and calender-specific death rates. Statistical significance (P value) of results was based upon the Poisson distribution. RESULTS: Among plasterers, statistically significant elevated mortality was observed for asbestosis, where the PMR reached 1,657 (P < 0.01) with eleven observed deaths and less than one death expected, for lung cancer (PCMR = 124, P < 0.01), and for benign neoplasms (PMR = 210, P < 0.05). Among cement masons, statistically significant elevated mortality was observed for cancer of the stomach (PCMR = 133, P < 0.01), benign neoplasms (PMR = 132, P < 0.01), and poisonings (PMR = 159, P < 0.05). Except for poisonings, which were not thought to be occupationally related, all of the statistically significant results occurred among those members who entered the union prior to 1950. However, the risk for lung cancer among plasterers was still elevated among those entering the union after 1970 as was the risk for stomach cancer among cement masons who entered the union after 1950. CONCLUSIONS: The present study suggests that plasterers and cement masons still have elevated risks for certain diseases, especially lung and stomach cancer. Therefore, union members currently living should be screened for asbestos-related diseases and educated about the future risks for these diseases.

Mortality among production workers in pulp and paper mills.

A cohort of 3,572 pulp and paper mill workers employed for at least one year between 1945 and 1955 was followed through 31 March 1977. Vital status was determined for 99% of the cohort. The 915 deaths observed were 79% of the number expected on the basis of comparable United States mortality rates. Statistically nonsignificant excesses of deaths due to lymphosarcoma and reticulosarcoma and to stomach cancer were observed. These findings tend to corroborate reports based on state vital statistics, and preliminary case-referent and population-based studies of workers in the pulp or paper industries. No deaths due to nasal cancer were observed, but only 0.6 were expected. When process-specific analyses were conducted, the excess risk of lymphosarcoma and reticulosarcoma was increased only for men who worked in sulfate mills. The excess risk of stomach cancer was limited to men who worked in sulfite mills. Process-specific standardized mortality ratios for these causes were highest after 20 years since first employment in the mills.

Prenatal participation in WIC related to Medicaid costs for Missouri newborns: 1982 update.

This study replicates a 1980 evaluation of WIC prenatal participation in Missouri by using a file of 9,086 Missouri Medicaid records matched with the corresponding birth records. This file was divided into a WIC group containing 3,261 records and a non-WIC group of 5,825 records. The 1982 results generally confirm the 1980 results, with the 1982 findings showing slightly improved pregnancy outcomes for WIC participants and slightly reduced benefit-to-cost ratios compared with the 1980 findings. In 1982, WIC participation was found to be associated with an increase in mean birth weight of 31 grams and reductions in low birth weight rates (statistically significant) and in neonatal death rates (not statistically significant). The reduction in each rate was 23 percent. WIC participation was also associated with a reduction in Medicaid costs for newborns reported within 45 days of birth amounting to $76 per participant. For every dollar spent on WIC, about 49 cents in Medicaid costs were apparently saved. However, wide 95 percent confidence intervals ($.07, $.90) make it difficult to determine precisely what impact WIC has on Federal and State budget outlays.

Differential features of motor neuron disease mortality in Spain.

BACKGROUND: The objective of this study was to describe the temporal and spatial patterns of motor neuron disease (MND) in Spain. METHODS: We studied data where MND was stated as the principal cause of death in official statistics from Spain. Time trends were analysed for age-, sex-specific and age-adjusted rates for the period 1951-1990. Age-adjusted mortality and relative risk, obtained by Poisson regression adjusting for age, were calculated for each province from deaths during the period 1975-1988. Maps were constructed using log transformed rates. Statistical significance of spatial aggregation was assessed using the Ohno et al. test. RESULTS: The 1951-1990 mortality rate, age- and sex-adjusted to the European population, for the population aged > or = 40 years was 1.49 per 100,000; 1.90 and 1.21 for males and females respectively. In general, mortality increased with age. Age-adjusted rates rose until 1960, dropped by 70% during the 1960s and declined slightly over the 1951-1990 period as a whole. From 1970 onwards MND mortality rose evenly, particularly in the 60-69 age group. A North-South gradient was suggested for both sexes with statistically significant clustering in the Northern coastal regions and--for males alone--in the Midwest provinces. CONCLUSIONS: Mortality from MND in Spain displayed a magnitude and recently rising temporal trend similar to that described in several other countries. Specific traits were: a decrease during the 1960s, which has been described for Japan only, as well as spatial heterogeneity and a predominant recent increase among the 60-69 age group. The determinants of these unusual MND mortality patterns are unknown.
