Reliability of data sources for poisoning deaths in Massachusetts.

The authors analyzed poisoning-related deaths in Massachusetts from 1986 and 1987 recorded in three datasets: poison center records, death certificate, and state medical examiner's office records. While 714 such deaths were found, 551 of these were prehospital deaths recorded within the medical examiner's office but not by the poison center. The poison center was not consulted in over 47% of the poisoning deaths occurring in Massachusetts hospitals. Conversely, 15% of deaths were reported to the poison center but were not found either in death certificate or medical examiner records. Concordance between all three datasets for recording the 163 poisoning-related hospital deaths was only 17%. The authors conclude that reliance on a single data source underestimates and potentially misrepresents both the numbers and types of poisoning deaths occurring in the state. They also believe the files of the medical examiner are an underappreciated, rich source of data concerning out-of-hospital deaths due to poisonings and intoxications. Their findings suggest that the regional poison center is an underused resource for the management of seriously poisoned patients. There is a need for a better working relationship between poison centers and area hospitals so that all serious intoxications and poisonings are reported to the poison center in a timely fashion.

Life-course experiences and mortality by adult social class among young men.

Circumstances over the life-course may contribute to adult social class differences in mortality. However, it is only rarely that the life-course approach has been applied to mortality studies among young adults. The aim of this study is to determine to what extent social class differences in mortality among young Finnish men are explained by living conditions in the parental home and life paths related to transitions in youth. The data for males born in 1956-60 based on the 1990 census records are linked with death records (3184 deaths) by cause of death for 1991-98, and with information on life-course circumstances from the 1970, 1975, 1980, and 1985 censuses. Controlling for living conditions in the parental home-social class, family type, number of siblings, language and region of residence-reduced the high excess mortality of the lower non-manual (RR 1.51, 95% CI: 1.28-1.79), skilled manual (RR 2.94, 2.54-3.40), and unskilled manual class (RR 4.08, 3.51-4.73) by 10% in all-cause mortality. The equivalent reduction for cardiovascular disease was 28% and for alcohol-related causes 16%. The effect of parental home on mortality differences was mainly mediated through its effect on youth paths (pathway model). Educational, marital, and employment paths had a substantial effect-independent of parental home-on social class differences from various causes of death. When all these variables were controlled for adult social class differences in cause specific mortality were reduced by 75-86%. Most of this reduction in mortality differences can be attributed to educational path. However, marital and employment paths had their independent effects, particularly on the excess mortality of unskilled manual workers with disproportionately common exposure to long-term unemployment and living without a partner. In summary, social class differences in total mortality among men in their middle adulthood were only partly determined by parental home but they were mainly attributable to educational, marital, and employment paths in youth.

Is length of life predictable?

A random sample of death records of adult males from the period 1967 to 1970 was chosen from the South Australian Registry of Births, Deaths, and Marriages. The natural parents of these individuals were identified by cross-referencing to birth certificates, and an extensive search was made of the death records for these parents. In this manner random families were selected for which, where possible, the cause of death and length of life of each family member were determined. Here, we analyze the association between sons and their parents in length of life and report the statistically useful correlations that were found. These correlations enable the calculation of a life table for a male conditional on his current age and the lifetimes of his parents. Comparisons are made with the uninformed population life table based solely on sex and year of birth.

[How we use opioid drugs on patients with neoplasms].

OBJECTIVE: To find the pattern of use of opiate drugs for treating pain in terminal cancer patients. DESIGN: Retrospective descriptive study. SETTING: Gavà 2 Health Centre, located in Barcelona's industrial belt. MATERIAL AND METHOD: Systematic review of the clinical records for the deaths recorded between May 1993 and March 1998. The following variables were recorded: age, sex, cause and place of death, professional attending patient during terminal phase, use of opiates (type, how they were taken, dosage and length of treatment) and prescribing doctor. RESULTS: Of the 429 deaths reviewed, 100 (23%) were caused by neoplasm (68% males), with an average age of 69 +/- 3 years. More than half the patients (55%) died at home. In the terminal phase they were mainly attended (69%) by their Primary Care team. 52% of the patients were given opiates, with morphine being the most common (71.1%), followed by codeine (40.3%) and tramadol (17.3%). The general practitioner was the prescribing agent in 69.2% of the cases. 76% of the patients who took codeine did so at infra-therapeutic doses (< 120 mg per day). Similarly, insufficient doses of morphine (< 60 mg per day) were given to half the patients who received it. 21.62% only took it during a period of 5 days or less before death. CONCLUSIONS: Primary care teams are taking on steadily greater protagonism in caring for terminal cancer patients. Although a large number of these patients are treated with opiates, these are given at often insufficient doses and for too short time periods.

Renal-related deaths in Australia 1997-1999.

BACKGROUND: Despite marked increases in cases of treated end-stage renal disease in Australia, little is known about renal disease mortality. AIMS: To quantify the contribution of renal diseases to mortality in Australia and to explore the relationship between renal disease and other common diseases as causes of death. METHODS: Data from the Australian Bureau of Statistics on underlying and associated causes of death (based on death certificates) were examined for deaths occurring in 1997-1999 and registered by the end of 1999. Causes of death were coded according to the International Classification of Diseases, 10th Revision (ICD-10). Several causes outside the ICD-10 chapter on diseases of the genito-urinary system (e.g. diabetic renal disease, hypertensive renal disease and congenital malformations of the kidney) were included as renal. RESULTS: Of 378,832 recorded deaths, renal disease was coded as the underlying cause for 7888 (2.1%) and as an associated cause for an additional 28,012 (7.4%). Almost all renal deaths (98.4%) had at least one other cause of death recorded on the death certificate. CONCLUSIONS: The contribution of renal disease to Australian mortality has been underestimated because of historical reliance on a single (underlying) cause of death. Deaths involving renal disease usually occur in the context of multiple coexisting chronic and/or acute conditions.

Mortality in maximum security psychiatric hospital patients.

Numerous studies have mentioned to the high percentage of violent deaths in prison psychiatric hospitals, with suicide being the principal cause. The aim of this study was to analyze the circumstances related with the deaths recorded in a high security institution. Postmortem reports on all the deaths at the Alicante Psychiatric Prison between 1984 and 1997 were studied (36 cases of unnatural death and 28 of natural death). Of the violent deaths recorded 34 (94.4%) were suicides. Demographic, clinical and interpersonal variables factors were registered. In the cases of suicides, the method used, the place of death, season, month and time of suicide were analyzed. In our study, 64.7% of suicides were schizophrenic and 32.4% had inflicted self-harm previously. We found a statistically significant association between the cause of death (natural, suicide or homicide) and age, 47.1% of suicides being between the ages of 18 and 30 and 29.4% between the ages of 30 and 45. Natural causes predominated in older subjects. The prison population studied showed grave negative traits, mental illness and criminal behavior having forced them to the very edge of society. Our results were compared with the death and suicide rates of the general Spanish population.

A record-keeping system for a pigeon breeding and research colony.

Seven different records were used to monitor a 2,000-bird pigeon colony. A nest card was placed on each nest box to record current production. This information was collected monthly and transferred to a breeding pair record which was used to evaluate yearly reproductive performance as well as to maintain a record of the number of offspring produced. An individual record was maintained on each bird to record it life history and pedigree. Weekly, when new offspring were banded, a squab data sheet was taken into the pen to record the offspring's permanent leg band number, hatch date, strain, pen number, and parents' band numbers. An individual pen record was used to record the leg band numbers of each bird occupying each pen. A monthly death record and a health record were maintained to monitor the colony's health status. From examination of the death record, one could determine if the mortality was excessive and if any specific pens were involved. On the health record were recorded diet, monthly morbidity and mortality, results of monitoring programs, and any treatments rendered. The system provided ready accessibility do detailed records of production, pedigrees, pen locations of birds, colony health status, and the number, strain, and age of birds available for research.

Measuring the burden of disease: healthy life-years.

OBJECTIVES: This paper presents the background and rationale for a composite indicator, healthy life-year (HeaLY), that incorporates mortality and morbidity into a single number. HeaLY is compared with the disability-adjusted life-year (DALY) indicator, to demonstrate the relative simplicity and ease of use of the former. METHODS: Data collected by the Ghana Health Assessment team from census records, death certificates, medical records, and special studies were used to create a spreadsheet. HeaLYs lost as a result of premature mortality and disability from 56 conditions were estimated. RESULTS: Two thirds of HeaLYs lost in Ghana were from maternal and communicable diseases and were largely preventable. The age weighting in DALYs leads to a higher value placed on deaths at younger ages than in HeaLYs. This spreadsheet can be used as a template for assessing changes in health status attributable to interventions. CONCLUSIONS: HeaLY can aid in setting health priorities and identifying disadvantaged groups. The disaggregated approach of the HeaLY spreadsheet tool is simpler for decision makers and useful for country application.

Incidence and causes of mortality following acute orthopaedic and trauma admissions.

PURPOSE: To analyse the incidence and causes of mortality of orthopaedic and trauma patients. METHODS: Between March 1995 and October 2000, there were 594 (404 females) in-patient deaths (2.8%) with a mean age of 82.14 years (range, 21-102 years) out of 21,122 acute admissions. The cause of death and details of the acute episode were collected from the hospital records, death certificates and postmortem examinations. Data collected were computerised and analysed using the Astute statistical package, University of Leeds. RESULTS: The most common primary diagnosis on admission was fracture neck of femur 392 (69.1%; P = 0.001). In total, 443 (78.1%) patients underwent surgical intervention of their injuries prior to mortality with 21 patients (4.7%) dying on the same day of the operation. The mean number of days between the initial surgical intervention and death was 22.3 days (range, 0-154 days). Of the patients who were treated non-operatively, 124 died due to poor medical condition (4 [3.2%] died within 24 h, 66 [51.6%] died within the first week and the rest died thereafter). In the death certificate, the most common primary cause of death recorded in the group of patients of 64 years of age and below was cancer followed by multi-organ failure. In the age group of 65 years and above, the most common primary cause of mortality was pneumonia followed by heart failure and myocardial infarction. CONCLUSIONS: In orthopaedic and trauma patients below the age of 65 years, the most common cause of death appears to be cancer followed by multiple system organ failure; in the elderly, pneumonia predominates followed by heart failure and myocardial infarction. Proximal femoral fractures accounted for 70% of the deaths.

The impact of smoking on use of hospital services: the Busselton study.

OBJECTIVE: To use the Busselton study to estimate the impact of smoking on hospital use in Australia. METHODS: People on the electoral roll in Busselton in 1978 were invited to attend a survey where smoking habits were measured. 3,230 people aged 25 to 79 at the survey were followed until 1994 by record linkage to death records and to the Western Australian Hospital Morbidity Data System. Hyper Poisson regression was used to estimate ratios of hospital separation rates and mean bed day usage according to the 1978 smoking status. RESULTS: Compared with never smokers, current smokers had hospital separation rates that were 1.32 (95% confidence interval 1.16-1.49) times higher and used 1.40 (1.20-1.65) times as many hospital bed days. Former smokers had rates midway between never and current smokers. Separations due to neoplasms, circulatory disorders and respiratory disorders were all more frequent in current than in never smokers. Estimates of hospital use in Australia due to smoking were about two times higher than those previously published using different methods. CONCLUSIONS: Smoking is a major contributor to hospital use in Australia. People who stop smoking reduce their risk of hospitalisation. IMPLICATIONS: Smoking has a major impact on hospital use, which can be reduced by successful smoking cessation programs.

Underlying cause of death as recorded for multiple sclerosis patients: associated factors.

The coding of multiple sclerosis (MS) as underlying cause of death (UCD) on the death certificate provides an important epidemiologic resource for both descriptive and analytic studies. However, not all deaths among MS patients will be so coded. We investigated the effect on estimated occurrence of MS and on characteristics of MS patients when only UCD codes are used to identify cases. Of 2329 MS patients living in Los Angeles County (California) or King/Pierce Counties (Washington) in 1970, 438 had died by 1980. Only 53% of the deaths were coded to MS; 47% were attributed to other causes. Based on our comparisons, the use of only MS-coded deaths to describe decedents would: underestimate the age at MS onset; overestimate the female:male ratio; underestimate age at death; and underestimate duration of MS. Also, the percentage of MS-coded deaths decreased with lengthening duration of follow-up of these prevalent cases. The effect of using only UCD codes to report characteristics of decedents with other chronic diseases may well be similar.

Gender and place of death from coronary artery disease in Washington State.

Men may be more likely than women to die outside the hospital from coronary artery disease, whereas women may be as likely as men to die inside the hospital. This study used Washington State death records to compare death rates from coronary artery disease inside and outside the hospital for women and men from 1980 to 2001. For in-hospital deaths, the men:women ratio of deaths was 1.6 in 1980 and 2001; for out-of-hospital deaths, the ratio decreased slightly from 2.6 in 1980 to 2.3 in 2001. These findings support the contention that, despite significant decreases in mortality, men continue to have higher rates of death outside and inside the hospital than do women, although there has been a slight decrease in male:female mortality for deaths outside the hospital.

Correlates of early hospital readmission or death in patients with congestive heart failure.

Among patients with heart failure who survive an admission to the hospital, those who are readmitted or die soon after discharge may warrant special attention. Therefore, we prospectively followed 257 patients admitted nonelectively to an urban university hospital, with a complaint of shortness of breath or fatigue and evidence of congestive heart failure on admission chest radiograph, who were discharged alive. Through survey of patients and families, review of the hospital computer system, and a search of the National Death Index, we recorded death and hospital readmission. Within 60 days of discharge, 13 patients (5%) died and 82 (32%) died or were readmitted to the hospital. Using Cox proportional-hazards modeling, the multivariable correlates of readmission or death were single marital status (adjusted hazard ratio [HR] 2.1, 95% confidence interval [CI] 1.3 to 3.3), Charlson Comorbidity Index score (HR 1.3 per point to maximum 4 points, 95% CI 1.1 to 1.6), admission systolic blood pressure of < or = 100 mm Hg (HR 2.8, 95% CI 1.6 to 5.0), and absence of new ST-T-wave changes on the initial electrocardiogram (HR 1.9, 95% CI 1.1 to 3.3). Self-reported patient compliance and clinical instability at discharge were not correlates. Almost all patients stratified by these factors had at least a 25% risk of readmission or death. Our independent correlates of readmission or death support the importance of both medical and social factors in the pathway to clinical decline. However, we could not reliably identify a truly low-risk group. Interventions to decrease early readmission or death among patients with heart failure should target both medical management and the adequacy of social support, and probably need to be applied to all admitted patients.

Deaths associated with inhalant abuse in Virginia from 1987 to 1996.

Inhalant abuse has existed for a considerable period of time and it is currently one of the most prevalent drug abuse problems in the world. One repercussion from using these compounds is that abuse may result in lethality. In an attempt to better understand the deaths associated with inhalant abuse, the authors surveyed the death records from the Commonwealth of Virginia from 1987 to 1996. Examination of the state records identified 39 deaths related to inhalant abuse during this time period. While no significant increase or decrease in the death rate was observed across the time period investigated, all regions of Virginia were affected, with the rates being highest in the northern and eastern regions of the state. Age of death ranged from 13 to 42 years with the majority of deaths (70%) occurring at 22 years of age or younger. Ninety-five per cent of the individuals were male, with volatile substance abuse deaths accounting for 0.3% of all deaths in males aged 13-22 years. The chief volatile substances used were gas fuels (46%), predominately butane and propane, chlorofluorocarbons (26%), chlorinated hydrocarbons and alkylbenzenes (21%), and other volatile substances including volatile anesthetics. Deaths associated with the abuse of butane and toluene were more likely to be traumatic, but all substances appeared capable of killing directly by their toxic effects, probably through cardiac and/or respiratory mechanisms. The ramifications of these findings for regulation and prevention are addressed.

The incidence and aetiology of stroke in the Caerphilly and Speedwell Collaborative Studies I: methods and incidence of events.

Stroke mortality and morbidity remain high despite downward trends in incidence and case fatality. Population-based longitudinal studies which include collection of risk factor data are required for a better understanding of stroke aetiology. From a representative cohort of men from South Wales and South-west England, followed up for a median of 17 y, details of possible cerebrovascular events were collected from questionnaires, hospital admission data, general practitioner records, death certificates, radiology records and post-mortem reports. Radiology records, and strokes and transient ischaemic attacks were independently validated. There were 433 strokes and 163 transient ischaemic attacks identified during follow-up. Of these, 333 were the first ever in a lifetime strokes of which 139 were definite ischaemic, 20 were haemorrhagic and 168 were probable ischaemic strokes. The crude incidence rate for stroke was 445 (95% confidence interval 398-493) per 100 000 person years. The age-standardised rates for 10 y age-bands were: 45-54 y 91 (10-172); 55-64 y 351 (269-432) and 65-74 y 855 (669-1040). The 30 d case-fatality rate was 21.0% (70/333) for all strokes and 19.2% (60/312) for ischaemic strokes. For transient ischaemic attacks the age-standardised incidence rates for the same 10 y age bands were 92 (4-179), 111 (64-157), and 273 (167-80), respectively. These rates for stroke transient ischaemic attack are likely to be accurate given the high ascertainment of events in this representative population of middle-aged men. Such studies, reporting reliable measures of cerebrovascular events, are important for measuring burden of disease, and for analysis of risk factor associations to help improve understanding of stroke aetiology and inform preventive efforts.

Causes of death among elderly Jews in New York City, 1979-1981.

Important differentials in mortality exist among ethnic and religious groups in the US but available statistics frequently preclude their examination. In the absence of mortality data for US Jews researchers have developed various alternatives, including using New York City's unique coding of death certificates according to religious affiliation of cemetery. Based on mortality rates for a sample of Medicare enrollees assumed to be representative of the Jewish population, in combination with New York City death record data, estimated death rates by sex and cause of death are developed for that city's elderly Jewish population. Comparisons made with rates for the white population of New York indicate low death rates for smoking-related diseases (lung cancer, chronic obstructive pulmonary diseases) among Jewish males. Other findings include above-average mortality from breast cancer among 65-74 year old Jewish women and from pancreatic cancer among Jewish women aged > or = 85. Below average mortality for both sexes is estimated for cerebrovascular disease and accidents, and for males from prostate cancer. The estimates produced are consistent with data from previous studies.

Mortality and medical comorbidity among patients with serious mental illness.

OBJECTIVES: This study examined mortality and medical comorbidity among patients with serious mental illness in Ohio. METHODS: Data for 20,018 patients admitted to an Ohio public mental health hospital between 1998 and 2002 were matched against state death records, and 608 deaths were identified. Leading causes of death and medical comorbidities, years of potential life lost (YPLL), and standardized mortality ratios were calculated for this population. RESULTS: Heart disease (126 persons, or 21 percent) and suicides (108 persons, or 18 percent) were the leading causes of death. The mean+/-SD number of YPLL was 32.0+/-12.6 years. The highest cause-specific mean YPLL was for suicides (41.7+/-10.3 years). Deaths from unnatural causes had higher mean YPLL than deaths from any other causes. Cause-specific mean YPLL were higher for women than for men, except for homicides, pneumonia and influenza, and heart disease. The aggregated standardized mortality ratio from all causes of death was 3.2, corresponding to 417 excess deaths (p<.001). Obesity (144 persons, or 24 percent) and hypertension (136 persons, or 22 percent) were the most prevalent medical comorbidities. CONCLUSIONS: This study demonstrated excess mortality among patients in Ohio with serious mental illness. Results highlight the need to integrate delivery of currently fragmented mental and physical health services and to target interventions that improve quality-of-life outcomes for this population.
