[Current deaths due to tuberculosis in France. Analysis of 126 deaths recorded in tuberculosis sufferers in 1975 and 1976 in the Bas-Rhin region (author's transl)].

The authors present a study involving 103 cases of death during active tuberculosis and 23 cases of death as a result of complications related to sequelae of tuberculosis recorded in the Bas-Rhin region in 1975 and 1976. Whilst amongst these 103 deaths, the majority concerned elderly individuals, there were nevertheless 20% of deaths due to tuberculosis below the age of 55. The majority of these tuberculosis sufferers had advanced pulmonary lesions where specific therapy had not had time to act. A certain number of deaths could have been avoided, even in the elderly subjects. Of the 23 cases of death due to sequelae, 2/3 died of respiratory failure and 1/5 of secondary aspergillus infection, illustrating the grave prognosis in certain sequelae of tuberculosis.

Live birth and infant death record linkage: methodological and policy issues.

Using records from Ohio annual vital statistics tapes, we describe a method for linking live birth and infant death certificates and for dealing with late-registered and unregistered births. In our 1985-87 Cleveland and East Cleveland study population, deceased infants with late-registered births were found to be similar to those with timely registered births. Approximately 4.6% of decedents, however, had unregistered births and these tended to be very premature infants from socially disadvantaged backgrounds who died shortly after delivery (including homicides following birth at home). We discuss the policy implications of failing to link infant deaths with unregistered births in studies of birth outcomes.

Linking birth and infant death records with assisted reproductive technology data: Massachusetts, 1997-1998.

OBJECTIVES: To link data from the US assisted reproductive technology (ART) registry with the Massachusetts birth-infant death file to create a comprehensive dataset on the circumstances surrounding conception and maternal and infant outcomes for a population of ART-conceived infants. METHODS: The authors sought to link data for 3704 ART-conceived live-born infants from 2703 deliveries in 1997-1998 involving Massachusetts resident mothers who gave birth in Massachusetts, Rhode Island, New Hampshire, or Connecticut to their corresponding Massachusetts birth record using a two-stage algorithm. Maternal and infant dates of birth served as the primary linkage variables. Maternal names for a subset of the ART-conceived infants were obtained and used in the second stage of the algorithm to confirm a sample of records that matched in Stage I, to resolve duplicate matches, and to link unmatched records. RESULTS: In Stage I, 78% of ART deliveries matched with only one Massachusetts record, 2% matched with two records, and 20% remained unmatched. Overall, the complete algorithm using maternal name data for a portion of records yielded an 89% linkage rate. Nearly all of the records that matched during Stage I that were evaluated with maternal name data in Stage II were confirmed as correctly linked. CONCLUSIONS: This project confirms that high-yield data linkage can be achieved in the absence of specific identifiers (e.g., name and social security number). Nonetheless, additional matches were achieved when name data were obtained. This linkage creates the first population-based file in the US capturing detailed information on ART births.

A study in causal discovery from population-based infant birth and death records.

In the domain of medicine, identification of the causal factors of diseases and outcomes, helps us formulate better management, prevention and control strategies for the improvement of health care. With the goal of exploring, evaluating and refining techniques to learn causal relationships from observational data, such as data routinely collected in healthcare settings, we focused on investigating factors that may contribute causally to infant mortality in the United States. We used the U.S. Linked Birth/Infant Death dataset for 1991 with more than four million records and about 200 variables for each record. Our sample consisted of 41,155 records randomly selected from the whole dataset. Each record had maternal, paternal and child factors and the outcome at the end of the first year--whether the infant survived or not. For causal discovery we used a modified Local Causal Discovery (LCD2) algorithm, which uses the framework of causal Bayesian Networks to represent causal relationships among model variables. LCD2 takes as input a dataset and outputs causes of the form variable X causes variable Y. Using the infant birth and death dataset as input, LCD2 output nine purported causal relationships. Eight out of the nine relationships seem plausible. Even though we have not yet discovered a clinically novel causal link, we plan to look for novel causal pathways using the full sample after refining the algorithm and developing a more efficient implementation.

[Integrity of the death records and problems of information transcription in 8 states of the Mexican Republic].

This paper states some of the main problems associated with the collection and processing of the information about deaths in Mexico. The results reported are in relation to the integrity and transcription problems found in 23 municipalities of eight states of the Republic of Mexico. The main results were: lack of continuity in the flow of information; different criteria in the handling of the several existing formats; incomplete documentation (medical death certificates, official registration and special concentration forms 823-824) in 39 percent, with a variation range of 2 to 72 percent depending of the particular degree of development in each state or county; the forms used to make up the national death statistics (forms 823-824) were not found in 21.5 percent of the cases, and transcription problems of the main variables (age, sex and cause of death), using as common denominator (total deaths) those registered at least in 2 documents, occurred in 26 percent of the age registers, 22.4 percent in the case of sex, and 51.6 percent in the cause of death variable.

Recording acute poisoning deaths.

Recording deaths from acute poisoning/substance abuse is not straightforward. The International Classification of Diseases (ICD), used to code mortality statistics, is aimed towards recording the underlying cause of death such as suicide or drug dependence rather than gathering data on poisoning per se. Despite the inherent difficulties clear trends can be observed from the data available for England and Wales. There have been marked changes in the compounds featuring in suicidal poisoning in the last 35 years reflecting changes in the availability of poisons, notably carbon monoxide and prescription barbiturates. However, although the number of poisoning suicides has decreased in the recent years, suicides from other means have increased in males (suicides in 1999, 75% male), hence there has been little change in the annual total of suicides. There are also striking differences in drug abuse- and volatile substance abuse (VSA)-related deaths between males and females. Drug abuse-related fatal poisoning (83% male, 1979-1999, European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) definition which does not include suicide), largely attributable to heroin and methadone, increased markedly during the 1990s, with a sharp rise in deaths attributed to accidental poisoning, although deaths involving methadone are now declining. VSA-related deaths (90% male, 1971-1999, almost entirely accidental deaths), nowadays predominantly from abuse of fuel gases (liquefied petroleum gas, LPG) from, for example, cigarette lighter refills, have declined from a peak in the early 1990s and are now becoming manifest in an older age group. These two latter instances especially provide examples where ICD-derived fatal poisoning data are inadequate and a 'poisons oriented' approach to data collection and analysis is necessary.

Reexamination of interpregnancy intervals and subsequent birth outcomes: evidence from U.S. linked birth/infant death records.

This study examines the net effects of the interpregnancy interval (time period from one birth to the next pregnancy) on the risks of preterm birth, intrauterine growth retardation, and infant mortality, for blacks and whites separately, using data from 1991 U.S. Linked Birth-Infant Death files. Results show that short (less than 7 months) and long (61+ months) intervals between pregnancies raise the risk of preterm birth and intrauterine growth retardation for both race groups, though the increase in risk is generally less than 30 per cent. Short intervals also raise (slightly) the risk of infant mortality after controlling for birthweight and gestational age.

The prevalence of hypertrophic cardiomyopathy in men: an echocardiographic population screening study with a review of death records.

The purpose of this study was to estimate the prevalence of hypertrophic cardiomyopathy (HCM) in 3607 men from the Reykjavik study of 1979-81. Of these, 452 men had an abnormal (group A) and 3155 a normal electrocardiogram. An echocardiographic control group of 128 men was selected from cohorts with a normal electrocardiogram (group B). Until 1987, 189 deaths had occurred, 59 from group A and 130 from cohorts with a normal ECG including 4 from group B. To identify subjects with HCM, survivors of groups A and B were examined by echocardiography and by review of all autopsy data and death certificates. HCM was found in 14 subjects from group A but none in group B. Two additional cases were found at autopsy in cohorts with a normal ECG. The prevalence of HCM in men with an abnormal and normal ECG was 3.6% and 0.8%, respectively. The overall prevalence was calculated to be 1.1% with a 95% confidence interval of 0.3-3.2%. Men with HCM reported more symptoms than others in groups A and B (P < 0.05-0.001). 25% were without symptoms. Asymptomatic ventricular arrhythmias were detected by Holter monitoring in 45% of men with HCM. The total annual mortality was 1.6% compared with 0.5% in the group with a normal ECG (P < 0.001).

Will the Scottish Cancer Target for the year 2000 be met? The use of cancer registration and death records to predict future cancer incidence and mortality in Scotland.

Cancer mortality data reflect disease incidence and the effectiveness of treatment. Incidence data, however, reflect the burden of disease in the population and indicate the need for prevention measures, diagnostic services and cancer treatment facilities. Monitoring of targets mandates that both be considered. The Scottish Cancer Target, established in 1991, proposed that a reduction of 15% in mortality from cancer in the under-65s should be achieved between 1986 and 2000. Each year in Scotland approximately 8300 persons under 65 are diagnosed with cancer and 4500 die from the disease. The most common malignancies, in terms of both incident cases and deaths, in the under-65s, are lung and large bowel cancer in males, and breast, large bowel and lung cancer in females. A decrease of 6% in the number of cancer cases diagnosed in males under 65 is predicted between 1986 and 2000, whereas the number of cases in females in the year 2000 is expected to remain at the 1986 level. In contrast, substantial reductions in mortality are expected for both sexes: 17% and 25% in males and females respectively. Demographic changes will influence the numbers of cancer cases and deaths in the Scottish population in the year 2000. However, long-term trends in the major risk factors, such as smoking, are likely to be the most important determinants of the future cancer burden.
