Unexpected out-of-hospital deaths in persons aged 85 years or older: an autopsy study of 1886 patients

PURPOSE: The aim of this study was to determine the causes of death in the very elderly. METHODS: We reviewed 24,081 consecutive autopsies performed over 10 years (1989 to 1998) at the Institute of Forensic Medicine, Vienna, Austria. We focused on autopsies of people aged 85 years or older who died unexpectedly out of hospital. RESULTS: The mean age of the 1886 patients (561 men and 1325 women) at the time of death was 88 +/- 3 years (range, 85 to 108 years). Thirty-one percent (n = 588) of those who died were described as having been previously healthy. Cardiovascular disease was the most common cause of death (n = 1465 [77%]). Thirteen percent (n = 246) died of respiratory illness, 5% (n = 94) of gastrointestinal disorders, and 3% (n = 53) of diseases of the central nervous system. Genitourinary and metabolic diseases were uncommon. CONCLUSION: Although this out-of-hospital sample is not representative of the entire elderly population, postmortem examinations emphasize the importance of cardiovascular diseases in causing unexpected deaths in older persons.     

Causes of death in Korean patients with systemic lupus erythematosus: a single center retrospective study.

OBJECTIVE: To determine the causes of death in Korean patients with systemic lupus erythematosus (SLE). METHODS: We evaluated retrospectively Korean SLE patients who were monitored in the Center for Rheumatic Disease in Kang-Nam St. Mary's Hospital from 1993 to 1997 and who died. RESULTS: Forty-three (7.9%) of 544 patients died. Comparison of demographics and disease activity indices between the deceased and the survivors showed that the age was older and C3 at presentation was lower in the deceased (n = 40) than the survivors (n = 453) (age: 33.8 +/- 13.6 versus 28.3 +/- 10.6 years, p = 0.02, C3: 36.8 +/- 21.4 versus 49.7 +/- 20.8 mg/dl, p = 0.03). Among 40 patients who died, the frequency and causes of death were as follows: 13 from infection (32.5%), 10 SLE-related factors (25.0%), 6 pulmonary hypertension (15.0%), 4 cerebrovascular accidents (10.0%), and 3 thrombotic thrombocytopenic purpura (7.5%). The majority of the SLE-related deaths were non-renal in origin, including 3 cerebral nervous system disease, 2 TTP, 2 acute pulmonary hemorrhage syndrome, 1 acute myocarditis, and 1 multi-system illness. SLE-related renal causes were responsible for only death. The major organisms of infection were gram negative bacilli (69.2%), primarily manifesting as sepsis or bacteremia (76.9%). The patients (n = 13) who died from infection had lower levels of complement and higher levels of anti-ds DNA antibody at presentation than those (n = 27) who died from the other causes (C3: 24.7 +/- 17.8 versus 41.7 +/- 21.5 mg/dl, p = 0.02, anti-dsDNA antibody: 68.0 +/- 73.5 versus 27.0 +/- 35.3 IU, p = 0.04). The mean steroid dose being administered one month before death was also higher in the patients who died of infection (30.5 +/- 15.2 versus 15.2 +/- 7.7 mg/day, p = 0.03). Patients who died of pulmonary hypertension, the third most common cause of mortality, showed extremely high pulmonary pressures at the initial diagnosis, with a short interval to death, and had less major organ involvement at death. There were no deaths due to coronary heart disease or neoplasm in this cohort. CONCLUSION: The most common cause of death in 544 Korean lupus patients was infection, mainly manifesting as gram negative bacterial sepsis. SLE-related factors (mostly non-renal) were the next most frequent cause. Death from infection was associated with higher disease activity at presentation and a higher dose of steroid used previously. Death due to pulmonary hypertension was common, whereas death due to coronary heart disease was absent.     

Causes of death and clinical diagnostic errors in extreme aged hospitalized people: a retrospective clinical-necropsy survey

BACKGROUND: There are little data on causes of death in extreme aged. We compared, using autopsy findings, main cause of death, overall disease status, and accuracy rate of clinical diagnoses in extreme aged and persons dying at younger ages. METHODS: We reviewed the complete clinical and autopsy records of 114 consecutive inpatients (97 women, 17 men, age range 97-106, mean 99, median 98) who died in Trieste, Italy, and represented 99% of all extreme-aged person deaths in the hospital and 70% in the area. The control group included 151 patients (66 women, 85 men, age range 65-74, mean 70, median 70) who died during the same period in that hospital. RESULTS: Vascular and respiratory diseases together caused 84% of deaths in extreme aged. The main causes of death were pneumonia (n = 40, 35%), pulmonary embolism (n = 16, 14%), stroke (n = 12, 11%), and myocardial infarction (n = 8, 7%). Cancer was responsible for 6% (7/114) of deaths in extreme aged and 42% (64/151) in the control group. In 5% of extreme aged, autopsy findings did not explain death. The premortem diagnostic accuracy rate for clinical diagnoses was good in 44% of extreme aged, sufficient in 18%, poor in 28%, and not evaluable in 10%, and was significantly different from controls. Pneumonia, pulmonary embolism, and myocardial infarction were markedly underestimated by clinicians in both groups. CONCLUSIONS: Extreme aged die mainly of cardiovascular and respiratory diseases and, in most cases, of acute events. Senescence is a rare cause of death. Death from cancer is substantially lower than in persons dying at younger ages. In contrast to no autopsy studies, most extreme aged in our study were found to have specific diseases that explained their deaths.     

Factors Associated with Home Versus Institutional Death Among Cancer Patients in Connecticut

OBJECTIVE: To assess the relationships between home death and a set of demographic, disease-related, and health-resource factors among individuals who died of cancer. DESIGN: Prospective cohort study. SETTING: All adult deaths from cancer in Connecticut during 1994. PARTICIPANTS: Six thousand eight hundred and thirteen individuals who met all of the following criteria: died of a cancer-related cause in 1994, had previously been diagnosed with cancer in Connecticut, and were age 18 and older at the time of death. MEASUREMENT: Site of death. RESULTS: Twenty-nine percent of the study sample died at home, 42% died in a hospital, 17% died in a nursing home, and 11% died in an inpatient hospice facility. Multivariate analysis indicated that demographic characteristics (being married, female, white, and residing in a higher income area), disease-related factors (type of cancer, longer survival postdiagnosis), and health-resource factors (greater availability of hospice providers, less availability of hospital beds) were associated with dying at home rather than in a hospital or inpatient hospice. CONCLUSIONS: The implications of this study for clinical practice and health planning are considerable. The findings identify groups (men, unmarried individuals, and those living in lower income areas) at higher risk for institutionalized death-groups that may be targeted for possible interventions to promote home death when home death is preferred by patients and their families. Further, the findings suggest that site of death is influenced by available health-system resources. Thus, if home death is to be supported, the relative availability of hospital beds and hospice providers may be an effective policy tool for promoting home death.     

How Does the Timing of Hospice Referral Influence Hospice Care in the Last Days of Life?

OBJECTIVES: To determine factors associated with the type of hospice care received in the last days of life and, in particular, how the timing of referral influences the use of continuous hospice home care and inpatient hospice care. DESIGN: Retrospective cohort study. SETTING: Twenty-one hospice programs across seven states under the ownership of one hospice parent provider. PARTICIPANTS: Hospice patients who were cared for and died between October 1, 1998, and September 30, 1999 (N = 28,747). MEASUREMENTS: Patient sociodemographic and clinical data were merged with use data from the provider's centralized information system to examine the factors associated with the differing levels of hospice care in the last week of life. In the last days of life, patients were classified as having received routine hospice home care only, having received continuous hospice home care, or having died in an inpatient hospice bed. RESULTS: Twenty-three percent of the patients received continuous hospice home care during the last week of life, and 34% died in an inpatient hospice bed. Patients with hospice stays of less than 7 days had a lower likelihood of receiving continuous hospice home care than those who had stays of more than 30 days (adjusted odds ratio (AOR) = 0.81, 95% confidence interval (CI) = 0.75-0.87). Patients with hospice stays of 14 days or less had a greater likelihood of dying in an inpatient hospice bed. Furthermore, patients with stays of less than 7 days who were referred from hospitals were six times likelier to die in an inpatient hospice bed than those who were referred from another source (AOR = 6.40, 95% CI = 5.74-7.14). Patients in nursing homes had a 93% lower likelihood of dying in an inpatient hospice bed than patients in the community without a live-in caregiver (AOR = 0.07, 95% CI = 0.03-0.19). Strong independent associations were observed between several other covariates and the study outcomes, particularly the covariates of which state hospice care was provided in and level of pain intensity. CONCLUSION: Findings suggest that continuous hospice home care in the last week of life is less likely to occur when patients have short hospice stays. Also, the probability of dying in an inpatient hospice bed is substantially greater for patients referred from hospitals and referred closer to time of death. Further work to determine the appropriateness of use of the different levels of hospice care is needed.     

Elderly outpatients' attitudes toward care in terminal stage disease]

Responses to a questionnaire regarding 1) dying at home, 2) being told of a diagnosis of cancer, and 3) hydration and nutrition, uses of narcotics for pain and dyspnea, oxygen treatment, antibiotics, transfusion and surgery in a near-vegetative state was obtained from 562 outpatients (73.4 +/- 8.6 years:mean +/- SD, men:women = 1.0:1.7). Dying at home was preferred by 64% and hospital death by 24%. Sixty and 65% of patients chose to be told of the diagnosis either in the last 3 months or at the early curable stage of the disease respectively, while only 53% wanted to be told precisely about their remaining estimated survival. If their spouse had terminal stage disease, 42% chose to inform the spouse of the diagnosis. Eighty percent chose palliative care, while 9.3% wished for intensive life-sustaining treatment. In a near vegetative state, tube feeding was desired by 8.7% and intravenous drip infusion by 39%; narcotics for pain or dyspnea were desired by 40 and 52%; oxygen or tracheostomy plus a respirator for dyspnea was chosen in 56 and 11% respectively; antibiotics for treatment of infection was desired by 38%; surgery for intestinal obstruction by 36 percent; transfusion for bleeding by 29%; and no treatment in any situation by 21%. Commonly expressed wishes were for a natural death, dying at home, and being told of the status of their disease, while details of palliative care were not well recognized.     

Critical Care Surgery Unit in general and digestive system surgery

In a 5-bed Critical Care Surgery Unit (UQCC) where surgeons are in charge of care, 126 patients admitted over 5 consecutive months were divided into 4 groups according to the treatment given: Group I (n = 49): elective gastrointestinal surgery; Group II (n = 52): emergency gastrointestinal surgery; Group III (n = 15): non-gastrointestinal surgery; Group IV (n = 10): medical treatment. The mean stay of all patients in the Surgical Critical Care Unit was 6 +/- 7.7 days and the global mortality was 7.9% (n = 10). The mean age of the patients who died was 71.5 +/- 7.3 years and 70% of the deaths corresponded to Group II. Forty percent of the patients who died had systemic candidiasis. Among the factors implicated in the mortality acute gastrointestinal pathology per se, the coexistence of chronic systemic disease and advanced age were prominent. We discuss the need for typifying the role of Surgical Critical Care Units in General and Gastrointestinal Surgery.     

Quality of dying in the ICU: ratings by family members

STUDY OBJECTIVES: To explore the quality of the dying experience and associations to higher quality ratings for people who died in an ICU. DESIGN: Retrospective study using medical record review and surveys of family members with the Quality of Dying and Death (QODD) instrument. SETTING: Four ICUs affiliated with a university and a Veterans Affairs Medical Center. PARTICIPANTS: Ninety-four family members of 38 ICU decedents. MEASUREMENTS AND RESULTS: We explored associations between components of the ICU experience and the overall rating of the quality of the dying experience. Overall, family members reported that symptoms were poorly controlled: pain under control most or all of the time in 47%, and breathing comfortably most or all of the time in 3% of patients. Families expressed a moderate and variable view of the quality of dying resulting in an overall ICU QODD score of 60 +/- 14 (on a scale of 0 to 100) [mean +/- SD]. Higher ICU QODD scores were associated with control of pain (r = 0.42, p = 0.009), control of events (r = 0.62, p < 0.001), a "preparation for death" aspect of the dying experience--feeling at peace with dying (r = 0.69, p < 0.001), and a "whole-person concern"--keeping one's dignity and self-respect (r = 0.50, p < 0.001). CONCLUSIONS: After adjusting for symptom and personal care scores, certain whole-person and preparation-for-death aspects of the dying process, and not aggressiveness of end-of-life care, remained the most associated to quality ratings. While future research should explore the important predictors of quality of dying in the ICU, this study suggests that care at the end of life in the ICU include not only managing pain, but also supporting dignity, respect, and peace, and maximizing patient control.     

Factors contributing to dying at home in elderly patients who received home care service]

This study examine whether around-the-clock medical support is a contributing factor to dying at home, and also tried to identify other such factors. Visiting nursing records of 81 elderly patients who died at home or in hospital after receiving home care at two facilities, one with and one without 24-hour medical support respectively were examined retrospectively. The subjects were divided into two groups: those who died at home and those who died in a hospital or nursing home. The two groups were compared in terms of clinical and sociodemographic characteristics and preferences for dying at home, expressed by patients, families and medical staff. Those who died at home showed a significantly higher rate of total dependence (84.6% vs. 48.1%) at month before death. Dying at home was significantly more preferred by all patients, families and medical staff. The major reason for hospitalization was rapid deterioration of the patients' condition. The facility with around-the-clock medical service had a higher rate of dying at home (42% vs. 27%, p = 0.18). Also, patients, families, and medical staff associated with their facility showed a higher preference for dying at home. We concluded from the above that the contributing factors for dying at home are: 1) total dependence level of ADL at one month before the death, and 2) preference for dying at home expressed by the patient, family and medical staff. This study suggests 24-hour medical support should be a requirement for in-home terminal care. Supporting advice from the staff to the family seems to be another contributing factor.     

Families' perception of the added value of hospice in the nursing home

OBJECTIVE: To determine if family members perceive that hospice improves the care of dying nursing home residents during the last 3 months of life. DESIGN: Mailed survey. PARTICIPANTS: Family members for all nursing home hospice enrollees in North Carolina during a 6-month period. MEASUREMENTS: After residents' deaths, family members answered questions about the quality of care for symptoms before and after hospice, the added value of hospice, the effect of hospice on hospitalization, and special services provided by nursing home staff or by hospice staff. RESULTS: A total of 292 (73%) of 398 eligible family members completed surveys. The average age of the nursing home residents who had received hospice was 79.5 years; 50% had cancer and 76% were dependent for self-care. In their last 3 months, 70% of decedents had severe or moderate pain, 56% had severe or moderate dyspnea, and 61% had other symptoms. Quality of care for physical symptoms was rated good or excellent by 64% of family before hospice and 93% after hospice (P<.001). Dying residents' emotional needs included care for moderate or severe depression (47%), anxiety (50%), and loneliness (35%). Quality of care for emotional needs was rated good or excellent by 64% of family before hospice and 90% after hospice (P<.001). Fifty-three percent of respondents believed hospice prevented hospitalizations. Family estimated the median added value of hospice to be $75 per day and described distinct special services provided by hospice and by nursing home staff. CONCLUSIONS: Family members believe that nursing home hospice improves quality of care for symptoms, reduces hospitalizations, and adds value and services for dying nursing home residents.     

Is Hospice Associated with Improved End‐of‐Life Care in Nursing Homes and Assisted Living Facilities?

OBJECTIVES: To examine whether hospice enrollment for nursing home (NH) and residential care/assisted living (RC/AL) residents near the end of life is associated with symptoms and symptom management, personal care, spiritual support, and family satisfaction. DESIGN: Structured, retrospective telephone interviews with family and staff who attended to NH and RC/AL residents in the last month of life. SETTING: A stratified sample of 26 NH and 55 RC/AL facilities in four states. Participants: Family members (n=97) and long-term care (LTC) staff (n=104) identified as most involved in care of 124 residents who died over a 15-month period. MEASUREMENTS: A variety of reported measures of care and symptoms before death, including the Discomfort Scale for Dementia of the Alzheimer's Type. RESULTS: Of 124 decedents, 27 (22%) received hospice services. Dementia was less common in hospice enrollees than in decedents who did not receive hospice care. Hospice enrollees more often had moderate/severe pain and dyspnea and received pain treatment and were more likely to receive assistance with mouth care and eating and drinking. There were no differences related to unmet need, and observed differences were largely eliminated when comparisons were limited to residents whose deaths were expected. CONCLUSION: Rates of hospice use observed in this study (22%) were considerably higher than previously reported, although persons with dementia may continue to be underreferred. Hospice use is targeted to dying residents with higher levels of reported pain and dyspnea. Because difference in care largely disappears in cases when death was expected, LTC staff seem to be well positioned to provide end-of-life care for their residents and are advised to remain sensitive to instances in which death may be expected.     

Dying with advanced dementia in the nursing home

BACKGROUND: Nursing homes are important providers of end-of-life care to persons with advanced dementia. METHODS: We used data from the Minimum Data Set (June 1, 1994, to December 31, 1997) to identify persons 65 years and older who died with advanced dementia (n = 1609) and terminal cancer (n = 883) within 1 year of admission to any New York State nursing home. Variables from the Minimum Data Set assessment completed within 120 days of death were used to describe and compare the end-of-life experiences of these 2 groups. RESULTS: At nursing home admission, only 1.1% of residents with advanced dementia were perceived to have a life expectancy of less than 6 months; however, 71.0% died within that period. Before death, 55.1% of demented residents had a do-not-resuscitate order, and 1.4% had a do-not-hospitalize order. Nonpalliative interventions were common among residents dying with advanced dementia: tube feeding, 25.0%; laboratory tests, 49.2%; restraints, 11.2%; and intravenous therapy, 10.1%. Residents with dementia were less likely than those with cancer to have directives limiting care but were more likely to experience burdensome interventions: do-not-resuscitate order (adjusted odds ratio [OR], 0.12; 95% confidence interval [CI], 0.09-0.16), do-not-hospitalize order (adjusted OR, 0.33; 95% CI, 0.16-0.66), tube feeding (adjusted OR, 2.21; 95% CI, 1.51-3.23), laboratory tests (adjusted OR, 2.53; 95% CI, 2.01-3.18), and restraints (adjusted OR, 1.79; 95% CI, 1.23-2.61). Distressing conditions common in advanced dementia included pressure ulcers (14.7%), constipation (13.7%), pain (11.5%), and shortness of breath (8.2%). CONCLUSIONS: Nursing home residents dying with advanced dementia are not perceived as having a terminal condition, and most do not receive optimal palliative care. Management and educational strategies are needed to improve end-of-life care in advanced dementia.     

The spectrum of tuberculosis in dialysis patients

Patients receiving dialysis therapy are known to be at increased risk of tuberculosis (TB). The aim of this study was to evaluate the frequency, clinical characteristics and course of TB disease in dialysis patients treated at our institution. Medical records of 330 regular haemodialysis (n=219) and continuous ambulatory peritoneal dialysis (n=111) patients (172 male, 158 female; mean age 55+/-16 y) who were cared for at our tertiary university hospital between December 2002 and January 2006 were retrospectively evaluated. Nine cases of TB (2.7%) occurred, in the following locations: vertebra (n=3), miliary (n=3), lymph nodes (n=1), peritoneum (n=2; one as peritionitis, 1 as an abscess). Four of these 9 patients died during the follow-up (mean time from diagnosis to death, 7 months); none of the deaths appeared to be caused by the disease itself. The incidence of TB disease in patients receiving renal replacement therapy is high, and occurs primarily in extrapulmonary sites.     

Are people with HIV in London able to die where they plan?

Being able to die where you plan is a measure of quality of life near death, in that it implies awareness of diagnosis and prognosis, adequate symptom control and involvement in decision-making in late-stage HIV disease. This study presents trends in place of death for patients attending a large central London HIV centre and examines whether patients dying over a 6-month period in 1994 were able to die where they planned. Early in the epidemic almost all people with HIV died in hospital, but in the late 1980s there was an increase in death at home and in hospices. Of people attending this hospital in 1994, 46 died in hospital, 31 at home, 20 in hospices and 2 abroad. A total of 59 of deaths were where the dying person had planned. Most unplanned deaths were in hospital, two-thirds being due to an unexpected deterioration which precluded planning. The rest were a mixture of people waiting for discharge to die elsewhere, and people who wished to continue active treatment. This pattern of place of death is unlikely to change in the near future. It is therefore essential that hospitals can provide for the needs of patients dying on acute wards.     

Costs of terminal care for people with AIDS

Despite the numerous studies on the costs of AIDS, little has been reported on the economic costs for terminal care. This study reports on the average monthly costs of care used in the last 6 months of life by a group of people with AIDS between 1984 and 1990. Hospital and outpatient visits, laboratory results, and medications were evaluated for all subjects. Standard costs (1990 dollars) were applied to all services. The 81 subjects received care in a large private medical practice located in northern California. The group was primarily male (98 percent), white (87 percent), and gay or bisexual (89 percent). Mean age at diagnosis of AIDS was 40.8 (SE = 1.1). Patients averaged a total of 2.9 (SE = 0.2) opportunistic infections (OIs) from the diagnosis of AIDS to death. Median survival was 13.2 months. The primary outcome measures were the components of the costs of terminal care: inpatient visits and outpatient costs. Covariates include location of death, year of death, and OIs. Average monthly terminal care resources included 8.3 days of in-hospital care, $8258 in costs for inpatients care, $840 in outpatient costs, and $9098 in total costs. Death at home increased in frequency (from 20 percent for 1984-1987 to 37 percent for 1987-1990). However, costs in the last 6 months of life did not change significantly as costs for patients who died in the hospital decreased and costs for patients who died at home increased over time. Policies that promote dying at home, while likely to affect patient quality of life, may not lower health care costs.     

Surgery for diverticulitis in renal failure

Twenty-five patients were operated on at the Brigham and Women's Hospital for colonic diverticulitis complicating treated renal failure during the period 1951 to 1983. Twelve patients had functioning renal allografts (eight cadaver, four living-related); 13 were on dialysis therapy. Six patients had polycystic kidney disease. The majority of patients had acute abdominal pain. Four had histories of chronic abdominal pain; nondiagnostic exploratory laparotomies were performed on two of these patients, who developed localized tenderness. The overall mortality in this series was 28 percent, with sepsis being the most common cause of death. Six of seven patients who died had free colonic perforations at surgery. Mortality correlated with age, with six of 14 patients (43 percent) over age 50 dying, as compared with one of 11 patients (9 percent) under age 50. There was no correlation between survival rate and type of surgery performed, dose of prednisone or azathioprine used, or type of treatment received for renal failure.     

Long-term prognosis after recovery from myocardial infarction: a community-based survey in Yamagata, Japan

OBJECTIVE: To assess the long-term prognosis after recovery from acute myocardial infarction (AMI) in the general population in Japan. PATIENTS AND METHODS: Among the 575,000 inhabitants of the Yamagata metropolitan area, a total of 117 patients suffered from first their AMI from April to December 1993. Thirteen patients (11%) died within four weeks after the onset. Of the remaining 104 patients, 101 (mean age, 69+/-12 years) were followed for an average of 65+/-5 months. RESULTS: Twenty-seven of the 101 patients (27%) died during the follow-up period. Compared with survivors, the patients who died were significantly older at the onset of AMI (74+/-12 vs. 67+/-12 years, p<0.01). More diabetic patients than non-diabetic patients died (42 vs. 21%, p<0.05) because of the higher frequency of non-cardiac deaths (29 vs. 11%, p<0.05). The total number of deaths of cardiac origin, including sudden deaths, was 11 (40%) and was lower than the number of definite non-cardiac deaths (n=15). The time from the onset of AMI to death was significantly shorter in cases of cardiac death than in cases of non-cardiac death (median, 16 vs. 45 months, p<0.01). Among non-cardiac deaths, deaths due to lung cancer and cerebral infarction were notable in men (standardized mortality ratio 278) and women (571), respectively. CONCLUSION: Non-cardiac death during long-term follow-up after AMI was more frequent than death of cardiac origin. Thus, preventive measures, including early treatment of complicating diseases, must be implemented to improve the long-term prognosis of patients with myocardial infarction.     

Instantaneous cardiac death in the posthospital period after acute myocardial infarction.

Sudden arrhythmic cardiac death is a major unresolved health problem, yet there is no agreement on the chronologic definition of sudden death. This retrospective study investigates the frequency distribution of the chronology of the terminal cardiac event in a large postinfarction population and identifies factors associated with instantaneous (< 1 minute) cardiac death. This study involved 229 patients enrolled in the Multicenter Diltiazem Post-infarction Trial who died during 2-year follow-up and had quantitative information on the chronology of the terminal event. Thirty-two percent of the cardiac deaths occurred instantaneously. Patients who died instantaneously were more likely (p < 0.05) to be men, to have a baseline ejection fraction < 0.40, and to have frequent (> or = 10/hour) and repetitive (> or = 3 in a row) ventricular ectopic complexes (VECs) on an ambulatory electrocardiogram than those who did not die instantaneously. Patients who died instantaneously received more digitalis and class IA antiarrhythmic agents and less beta blockers in the week before death than those dying noninstantaneously. Logistic regression analysis identified 3 independent factors that differentiated instantaneous from noninstantaneous death (relative risk; 95% confidence interval): frequent VECs (2.15; 1.11 to 4.17); digitalis (2.57; 1.31 to 5.06); and no beta blocker medication (2.90; 1.09 to 7.75). Instantaneous death (within 1 minute) was responsible for almost one third of the cardiac deaths that occurred in this postinfarction population. Frequent VECs, digitalis, and absence of beta-blocker therapy distinguished patients who died instantaneously from those who died noninstantaneously.
