Abstract
BACKGROUND Medical certification of cause of death (MCCD) provides valuable data regarding disease burden in a community and for formulating health policy. Inaccurate MCCDs can significantly impair the precision of national health information. OBJECTIVE To evaluate the accuracy of cause of death certificates prepared at two tertiary cancer care hospitals in Northern India during the study period (May 2018 to December 2020). METHOD A retrospective observational study at two tertiary cancer care hospitals in Varanasi, India, over a period of two and a half years. Medical records and cause of death certificates of all decedents were examined. Demographic characteristics, administrative details and cause of death data were collected using the WHO recommended death certificates. Accuracy of death certification was validated by electronic medical records and errors were graded. RESULTS A total of 778 deaths occurred in the two centres during the study period. Of these, only 30 (3.9%) certificates were error-free; 591 (75.9%) certificates had an inappropriate immediate cause of death; 231 (29.7%) certificates had incorrectly labelled modes of death as the immediate cause of death; and 585 (75.2%) certificates had an incorrect underlying cause of death. The majority of certificates were prepared by junior doctors and were significantly associated with higher certification errors. CONCLUSION A high rate of errors was identified in death certification at the cancer care hospitals during the study period. Inaccurate MCCDs related to cancers can potentially influence cancer statistics and thereby affect policy making for cancer control. IMPLICATIONS This study has identified the pressing need for appropriate interventions to improve quality of certification through training of doctors.

Abstract
OBJECTIVE This article describes the first digital clinical information system tailored to support the operational needs of a forensic unit in Greece and to maintain its archives. METHOD The development of our system was initiated towards the end of 2018, as a close collaboration between the Medical School of the University of Crete and the Forensic Medicine Unit of the University Hospital of Heraklion, Crete, where forensic pathologists assumed active roles during the specification and testing of the system. RESULTS The final prototype of the system was able to manage the life cycle of any forensic case by allowing users to create new records, assign them to forensic pathologists, upload reports, multimedia and any required files; mark the end of processing, issue certificates or appropriate legal documents, produce reports and generate statistics. For the first 4 years of digitised data (2017-2021), the system recorded 2936 forensic examinations categorised as 106 crime scene investigations, 259 external examinations, 912 autopsies, 102 post-mortem CT examinations, 804 histological examinations, 116 clinical examinations, 12 anthropological examinations and 625 embalmings. CONCLUSION This research represents the first systematic effort to record forensic cases through a digital clinical information system in Greece, and to demonstrate its effectiveness, daily usability and vast potential for data extraction and for future research.

Trends in cause-specific mortality among persons with Alzheimer's disease in South Carolina: 2014 to 2019. Front Aging Neurosci 2024; 16:1387082. [PMID: 38694259 PMCID: PMC11061437 DOI: 10.3389/fnagi.2024.1387082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Accepted: 04/05/2024] [Indexed: 05/04/2024] Open
Abstract
Introduction Inconsistencies of reports contributes to the underreporting of Alzheimer's disease (AD) on death certificates. Whether underreporting exists within South Carolina has not been studied. Methods We conducted a prospective, population-based study on a cohort of persons (N = 78,534) previously diagnosed with AD and died between 2014-2019. We linked vital records with the South Carolina Alzheimer's Disease and Related Dementias Registry to investigate their cause of death and survival rates. Descriptive analyses calculated frequencies of demographic and health-related characteristics. Turnbull's method estimated the survival probabilities for different subgroups of patients. Hazard ratios were computed from the Cox proportional hazards model, adjusting for the following confounding variables of age at diagnosis, education level, gender, and race. Results The top immediate cause of death was Alzheimer's disease among all racial groups, except for Native American/American Indian. More females (60.3%) were affected by AD compared to males (39.7%). There is a 25% probability of survival, beyond 5 years, after AD diagnosis. Black/African American AD patients have the smallest risk of all-cause mortality across all racial/ethnic groups (HR 0.87; 95% CI, 0.85-0.89). Individuals with lower education had a lower likelihood of mortality. Conclusion Although AD was not underreported in the state of South Carolina further research is needed to develop protocols around classification of deaths among those diagnosed with dementia and comorbidities, including cardiovascular disease, to ensure dementia is properly reported as we move to prevent and treat Alzheimer's disease by 2025 and beyond.

Abstract
Aim of the study The study examined the distribution of places of death in the Westphalian city of Muenster over an observation period of 20 years.Methods All death certificates issued in the city of Muenster from 2001, 2011, 2017, 2021 were evaluated by places of death (home (HO), hospital (HT), hospice (HP), nursing home (NH), other place (OP)). For hospital patients, deaths on intensive care units (ICU) and palliative care units (PAL) were also considered separately. Any medical information on cause of death was used to identify decedents with malignant tumor or dementia disease.Results A total of 14,240 death certificates were evaluated. A malignant tumor disease was documented in 34.0%, dementia in 11.1%. For the general population, the distribution of places of death was as follows (2001/2021; %): HO (24.0/14.6); HT (63.2/60.2) [ICU (13.3/24.6), PAL (0.0/10.9)], HP (3.8/4.9), NH (7.8/19.5), OP (1.1/0.7). Most tumor patients died in hospital (2021: 60.6%), fewer patients at home (2021: 15.4%). From 2001 to 2021, the proportion of cancer patients who died in a PAL increased significantly (+24.4%); hospices showed a moderate increase (+5.0%). A majority of dementia patients died in nursing homes (2021: 66.6%) and fewer patients at home (2021: 12.2%).Conclusion For the general population and for tumor patients, the hospital is the most common place of death and the nursing home for patients with dementia. Overall, deaths at home decreased continuously over time. For tumor patients, palliative care units and hospices are becoming increasingly important as places of death, and for dementia patients, nursing homes in particular.

Frequency and types of errors in clinician-composed death certificates for patients with or without autopsy in a hospital population. J Public Health (Oxf) 2024; 46:83-86. [PMID: 38061768 DOI: 10.1093/pubmed/fdad255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Indexed: 02/29/2024] Open
Abstract
BACKGROUND Death certificate (DC) errors are common. At our institution, all deaths have a preliminary death certificate (PDC) written by a clinician and then revised by a pathologist prior to the clinician signing the final death certificate (FDC). In autopsy cases, the FDC is signed by the pathologist who performs the autopsy. METHODS A total of 100 in-hospital deaths (50 with autopsy and 50 without) occurred in 2020 were arbitrarily selected from a tertiary care center. All PDCs and FDCs were compared to identify/classify errors as major (incorrect cause of death (COD) or significant contributing factors) or minor (abbreviations, inappropriate non-essential contributing factors, immediate/intermediate COD errors). Frequency of PDC errors was compared by autopsy status, duration of hospital stay and PDC author. RESULTS Ninety percent of cases had at least one PDC error and 39% had a major error. Major errors were more common in autopsy cases (50% versus 28%, P = 0.035), although minor/overall errors were not. Error rates did not significantly differ for the other variables assessed. CONCLUSIONS There is significance of having a pathologist review and revise DCs before they are signed. The increased frequency in major errors in cases with autopsy suggests that autopsy findings provided additional information to elucidate COD.

Abstract
Background Whenever possible, a person should die where they feel it is the right place to be. There is substantial global variation in home death percentages but it is unclear whether these differences reflect preferences, and there are major limitations in how the place of death is classified and compared across countries. Objectives EOLinPLACE is an international interdisciplinary research project funded by the European Research Council aiming to create a solid base for a ground-breaking international classification tool that will enable the mapping of preferred and actual places towards death. Design Mixed-methods observational research. Methods and analysis We combine classic methods of developing health classifications with a bottom-up participatory research approach, working with international organizations representing patients and informal carers [International Alliance of Patients' Organizations (IAPO) and Eurocarers]. First, we will conduct an international comparative analysis of existing classification systems and routinely collected death certificate data on place of death. Secondly, we will conduct a mixed-methods study (ethnography followed by longitudinal quantitative study) in four countries (the Netherlands, Portugal, Uganda and the United States), to compare the preferences and experiences of patients with life-threatening conditions and their families. Thirdly, based on the generated evidence, we will build a contemporary classification of dying places; assess its content validity through focus groups with patients, carers and other stakeholders; and evaluate it in a psychometric study to examine construct validity, reliability, responsiveness, data quality and interpretability. Ethics Approved by the ethics committee of the University of Coimbra, Faculty of Medicine (CE-068-2022) and committees in each of the participating countries. Discussion The findings will provide a deeper understanding of the diversity in individual end-of-life pathways. They will enable key developments such as measurement of progress towards achievement of preferences when care can be planned. The project will open new directions in how to care for the dying.

Abstract
OBJECTIVE Timely data on drug overdose deaths can help identify community needs, evaluate the effectiveness of interventions, and allocate resources. We identified variations in death investigation and reporting systems within and between states that affect the timeliness and accuracy of death certificate information. METHODS The HEALing Communities Study (HCS) is a community-engaged, data-driven approach to combating the opioid crisis in 67 communities in 4 states: Kentucky, Massachusetts, New York, and Ohio. HCS conducted a survey of coroners and medical examiners to understand variability in drug overdose death data. We compared survey results in Massachusetts, New York, and Ohio with national data to investigate the completeness of provisional death counts by type of death investigation system. RESULTS Communities in each HCS state had different ways of collecting and reporting mortality data. Completion of death certificates for drug overdoses ranged from <2 weeks in 23% (7 of 31) of those surveyed to more than 3 months in 10% (3 of 31) of those surveyed. Variabilities in the timeliness of reporting drug overdose deaths were not associated with type of coroner or medical examiner office in each state, urban versus rural setting, or specificity of drug information on the death certificate. CONCLUSION Having specific drug information on the death certificate may increase death certificate quality, comparability, and accuracy. We recommend the following: (1) all coroners and medical examiners should be trained on conducting death investigations, interpreting toxicology reports, and completing death certificates; (2) 1 office in each state should oversee all coroners and medical examiners to increase data consistency; and (3) communities should identify and address barriers to timely death certification.

Abstract
OBJECTIVES To identify the frequency and types of errors in the Medical Certificate Cause of Death (MCCD) completed by hospital medical officers for deceased older patients. METHODS Among 127 deaths in a tertiary hospital acute geriatric unit between 1 July 2021 and 30 June 2022, a cause of death was documented for 116 patients (mean age 87.8, SD 5.7 years, 47% female, 39% from a nursing home). The MCCD was evaluated for errors as compared to national guidelines based on five criteria: mechanism without underlying cause; competing causes; improper sequencing; incomplete data; and use of abbreviations. The level of training of the documenting medical officer and whether the MCCD was completed out of usual working hours was evaluated with respect to errors. RESULTS At least one error was present in 60 (52%) of the MCCD evaluated, and there were two or more errors in 16 (14%). Most commonly, documenting competing causes of death was found in 45 (39%) of all MCCD, followed by missing data (10%) and improper sequencing (9%). MCCDs were mostly completed by postgraduate year (PGY) 1 or 2 medical officers (78%) and out-of-hours (in 72%). There was no significant difference in frequency of errors between junior and senior medical officers (p = 0.52) or if it was completed within or out-of-hours (p = 0.14). CONCLUSIONS The MCCD for deceased hospital patients often contained an error. Major improvement in the quality of death certification is needed among all medical officers.

Abstract
Background: Death in hospital rather than at home is becoming more prevalent, even among terminally ill patients receiving home-based care. Identifying trends in places of death is crucial to care policy, especially for aging populations as in Taiwan. Aim: To identify changes in the places of natural death of Taiwanese individuals for various causes of death. Design: A population-based observational study was conducted. Setting: Anonymous data for the period 2000-2020 from the Death Database of Taiwan's National Center for Health Statistics Data were obtained and analyzed. Results: In 2000, 60.1% of natural deaths occurred in the home, whereas in 2020, this percentage was only 36.8%; conversely, the percentage of deaths in hospital increased from 34.4% in 2000 to 56.1% in 2020. Deaths in a nursing home or long-term care facility were found to account for only 3.8% of all natural deaths in 2020. Dementia was the cause of death for which the proportion of institutional deaths was highest, although this proportion was <10% for most years. We applied the joinpoint regression model to estimate trend changes in places of death. During the study period, the places of death in Taiwan changed significantly, the average annual percent changes for hospital deaths over the 21-year period was 2.54% (confidence interval [CI]: 2.04 to 3.03), and for home deaths was -2.69% (CI: -3.26 to -2.13). Conclusions: The detailed findings of this national study can offer insight into potential future clinical burdens and lead to better health policy decisions for Taiwan.

Abstract
Background Relatively little is known about where foreign-born individuals die in Sweden and how birth region might influence place of death. Thus, there is a need for population-based studies investigating place of death and associated factors among foreign-born individuals. Objectives The aim of this study was to identify variations in place of death among foreign-born individuals residing in Sweden and to compare place of death between the foreign- and domestic-born population. We also examine the association between place of death, underlying cause of death and sociodemographic characteristics among the foreign-born population. Design A population-based register study. Methods All deceased individuals ⩾18 years of age in Sweden with a registered place of death between 2012 and 2019 (n = 682,697). Among these, 78,466 individuals were foreign-born. Univariable multinomial logistic regression modelling and multivariable multinomial logistic regression analyses were performed. Results Overall, hospital was the most common place of death among the foreign-born population. However, there were variations in place of death related to region of birth. Compared to domestic-born, a higher proportion of foreign-born individuals dies at home, the majority of whom were born on the African continent. Conclusion Region of birth is one of the several factors associated with place of death among foreign-born individuals. Further research is needed to explore both preferences and barriers to place of death among foreign-born individuals.

Abstract
OBJECTIVE To examine suicide deaths among working-age residents in Massachusetts and to determine industries and occupations with high numbers and rates of suicides. METHODS The Massachusetts Violent Death Reporting System and Massachusetts death certificates were used to analyze suicide deaths from 2016 to 2019. Counts and rates were generated by demographics and industry and occupation groupings. RESULTS There were 2199 working-age Massachusetts residents who died by suicide. Higher suicide rates were associated with being male, 65 years or older, White, and non-Hispanic or having military background. Suicide rates were higher among the construction industry sector and the construction and extraction occupational group compared with the average rate for all Massachusetts workers. CONCLUSIONS Suicide rates differed between industries and occupations, suggesting that work-related factors may play a role and should be considered when planning outreach initiatives and interventions.

Abstract
BACKGROUND Research and reporting of mortality indicators typically focus on a single underlying cause of death selected from multiple causes recorded on a death certificate. The need to incorporate the multiple causes in mortality statistics-reflecting increasing multimorbidity and complex causation patterns-is recognized internationally. This review aims to identify and appraise relevant analytical methods and practices related to multiple causes. METHODS We searched Medline, PubMed, Scopus, and Web of Science from their incept ion to December 2020 without language restrictions, supplemented by consultation with international experts. Eligible articles analyzed multiple causes of death from death certificates. The process identified 4,080 items of which we reviewed 434 full-text articles. RESULTS Most articles we reviewed (76%, n = 332) were published since 2001. The majority of articles examined mortality by "any- mention" of the cause of death (87%, n = 377) and assessed pairwise combinations of causes (57%, n = 245). Since 2001, applications of methods emerged to group deaths based on common cause patterns using, for example, cluster analysis (2%, n = 9), and application of multiple-cause weights to re-evaluate mortality burden (1%, n = 5). We describe multiple-cause methods applied to specific research objectives for approaches emerging recently. CONCLUSION This review confirms rapidly increasing international interest in the analysis of multiple causes of death and provides the most comprehensive overview, to our knowledge, of methods and practices to date. Available multiple-cause methods are diverse but suit a range of research objectives. With greater availability of data and technology, these could be further developed and applied across a range of settings.

Flaws and uncertainties in pandemic global excess death calculations. Eur J Clin Invest 2023:e14008.

Abstract
Several teams have been publishing global estimates of excess deaths during the COVID-19 pandemic. Here, we examine potential flaws and underappreciated sources of uncertainty in global excess death calculations. Adjusting for changing population age structure is essential. Otherwise, excess deaths are markedly overestimated in countries with increasingly aging populations. Adjusting for changes in other high-risk indicators, such as residence in long-term facilities, may also make a difference. Death registration is highly incomplete in most countries; completeness corrections should allow for substantial uncertainty and consider that completeness may have changed during pandemic years. Excess death estimates have high sensitivity to modeling choice. Therefore different options should be considered and the full range of results should be shown for different choices of pre-pandemic reference periods and imposed models. Any post-modeling corrections in specific countries should be guided by pre-specified rules. Modeling of all-cause mortality (ACM) in countries that have ACM data and extrapolating these models to other countries is precarious; models may lack transportability. Existing global excess death estimates underestimate the overall uncertainty that is multiplicative across diverse sources of uncertainty. Informative excess death estimates require risk stratification, including age groups and ethnic/racial strata. Data to-date suggest a death deficit among children during the pandemic and marked socioeconomic differences in deaths, widening inequalities. Finally, causal explanations require great caution in disentangling SARS-CoV-2 deaths, indirect pandemic effects, and effects from measures taken. We conclude that excess deaths have many uncertainties, but globally deaths from SARS-CoV-2 may be the minority of calculated excess deaths.

Ascertainment of Incident Cancer by US Population-Based Cancer Registries Versus Self-Reports and Death Certificates in a Nationwide Cohort Study, the US Radiologic Technologists Study. Am J Epidemiol 2022; 191:2075-2083. [PMID: 35872590 PMCID: PMC10144614 DOI: 10.1093/aje/kwac121] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Revised: 03/23/2022] [Accepted: 07/06/2022] [Indexed: 02/01/2023] Open
Abstract
Follow-up of US cohort members for incident cancer is time-consuming, is costly, and often results in underascertainment when the traditional methods of self-reporting and/or medical record validation are used. We conducted one of the first large-scale investigations to assess the feasibility, methods, and benefits of linking participants in the US Radiologic Technologists (USRT) Study (n = 146,022) with the majority of US state or regional cancer registries. Follow-up of this cohort has relied primarily on questionnaires (mailed approximately every 10 years) and linkage with the National Death Index. We compared the level of agreement and completeness of questionnaire/death-certificate-based information with that of registry-based (43 registries) incident cancer follow-up in the USRT cohort. Using registry-identified first primary cancers from 1999-2012 as the gold standard, the overall sensitivity was 46.5% for self-reports only and 63.0% for both self-reports and death certificates. Among the 37.0% false-negative reports, 27.8% were due to dropout, while 9.2% were due to misreporting. The USRT cancer reporting patterns differed by cancer type. Our study indicates that linkage to state cancer registries would greatly improve completeness and accuracy of cancer follow-up in comparison with questionnaire self-reporting. These findings support ongoing development of a national US virtual pooled registry with which to streamline cohort linkages.

Abstract
Cocaine use is an increasingly frequent event, especially in young people, and can cause irreversible consequences, such as suicide. To evaluate the factors associated with cocaine use in the moments preceding to suicide. This is a population-based, cross-sectional, and analytical study conducted in the Brazilian Federal District by researchers from the Department of Health and the Civil Police Institute of Criminalistics. All people who died due to suicide in 2018 were included in the survey. Cocaine use was considered the dependent variable, and robust Poisson regression was performed to estimate the crude and adjusted prevalence ratios and their respective population confidence intervals. In 2018, 12,157 deaths were recorded, of which suicide accounted for 1.56% of all deaths. It was observed that being between 25 and 44 years old, male, and under the influence of alcohol or cannabis, had a strong positive association with cocaine consumption among suicide victims. Males, people with black skin, with lower level of education, with employment, and who were under the effect of the use of cannabis and/or alcohol in the previous hours of death had a higher propensity to consume cocaine immediately before suicide, with a moderate to strong magnitude of prevalence ratio. The findings of this research indicated the need for monitoring, by health services, of people most vulnerable to suicide through the consumption of psychoactive substances.

Abstract
BACKGROUND Prostate cancer (PC) mortality statistics in Estonia has shown inconsistencies with incidence and survival trends. The aim of this population-based study was to assess the accuracy of reporting PC as the underlying cause of death and estimate the effect of misattribution in assigning cause of death on PC mortality rates. MATERIAL AND METHODS The Estonian Causes of Death Registry (CoDR) and Cancer Registry provided data on all men in Estonia who died in 2017 and had a mention of PC on any field of the death certificate or had a lifetime diagnosis of PC. A blinded review of medical records was conducted by an expert panel to ascertain whether the underlying cause was PC or other death. We estimated the agreement between the underlying causes of death registered at the CoDR and those ascertained by medical review and calculated corrected mortality rates. RESULTS The study population included 655 deaths. Among 277 PC deaths registered at CoDR, 164 (59%) were verified by medical review. Among 378 other deaths registered at CoDR, 17 (5%) were ascertained as PC deaths by medical review. In total, the number of PC deaths decreased from 277 to 181 and the corrected age standardized (world) mortality rate decreased from 20 to 13 per 100 000 (1.5-fold overestimation, 95% confidence interval 1.2-1.9). CONCLUSIONS PC mortality statistics in Estonia should be interpreted with caution and possible overestimation considered when making policy decisions. Quality assurance mechanisms should be reinforced in the whole death certification process.

Physicians' Perceptions as Predictors of the Future Use of the National Death Information System in Peru: Cross-sectional Study. J Med Internet Res 2022; 24:e34858. [PMID: 35969435 PMCID: PMC9425167 DOI: 10.2196/34858] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Revised: 04/27/2022] [Accepted: 05/30/2022] [Indexed: 11/21/2022] Open
Abstract
Background A computer application called the National Death Information System (SINADEF) was implemented in Peru so that physicians can prepare death certificates in electronic format and the information is available online. In 2018, only half of the estimated deaths in Peru were certified using SINADEF. When a death is certified in paper format, the probability being entered in the mortality database decreases. It is important to know, from the user’s perspective, the factors that can influence the successful implementation of SINADEF. SINADEF can only be successfully implemented if it is known whether physicians believe that it is useful and easy to operate. Objective The aim of this study was to identify the perceptions of physicians and other factors as predictors of their behavioral intention to use SINADEF to certify a death. Methods This study had an observational, cross-sectional design. A survey was provided to physicians working in Peru, who used SINADEF to certify a death for a period of 12 months, starting in November 2019. A questionnaire was adapted based on the Technology Acceptance Model. The questions measured the dimensions of subjective norm, image, job relevance, output quality, demonstrability of results, perceived usefulness, perceived ease of use, and behavioral intention to use. Chi-square and logistic regression tests were used in the analysis, and a confidence level of 95% was chosen to support a significant association. Results In this study, 272 physicians responded to the survey; 184 (67.6%) were men and the average age was 45.3 (SD 10.1) years. The age range was 24 to 73 years. In the bivariate analysis, the intention to use SINADEF was found to be associated with (1) perceived usefulness, expressed as “using SINADEF avoids falsifying a death certificate” (P<.001), “using SINADEF reduces the risk of errors” (P<.001), and “using SINADEF allows for filling out a certificate in less time” (P<.001); and (2) perceived ease of use, expressed as “I think SINADEF is easy to use” (P<.001). In the logistic regression, perceived usefulness (odds ratio [OR] 8.5, 95% CI 2.2-32.3; P=.002), perceived ease of use (OR 10.1, 95% CI 2.4-41.8; P=.001), and training in filling out death certificates (OR 8.3, 95% CI 1.6-42.8; P=.01) were found to be predictors of the behavioral intention to use SINADEF. Conclusions The behavioral intention to use SINADEF was related to the perception that it is an easy-to-use system, the belief that it improves the performance of physicians in carrying out the task at hand, and with training in filling out death certificates.

Increased Deaths From Fungal Infections During the Coronavirus Disease 2019 Pandemic-National Vital Statistics System, United States, January 2020-December 2021. Clin Infect Dis 2022; 76:e255-e262. [PMID: 35717660 PMCID: PMC9214147 DOI: 10.1093/cid/ciac489] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Revised: 05/20/2022] [Accepted: 06/09/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19)-associated fungal infections cause severe illness, but comprehensive data on disease burden are lacking. We analyzed US National Vital Statistics System (NVSS) data to characterize disease burden, temporal trends, and demographic characteristics of persons dying of fungal infections during the COVID-19 pandemic. METHODS Using NVSS's January 2018-December 2021 Multiple Cause of Death Database, we examined numbers and age-adjusted rates (per 100 000 population) of deaths due to fungal infection by fungal pathogen, COVID-19 association, demographic characteristics, and year. RESULTS Numbers and age-adjusted rates of deaths due to fungal infection increased from 2019 (n = 4833; rate, 1.2 [95% confidence interval, 1.2-1.3]) to 2021 (n = 7199; rate, 1.8 [1.8-1.8] per 100 000); of 13 121 such deaths during 2020-2021, 2868 (21.9%) were COVID-19 associated. Compared with non-COVID-19-associated deaths (n = 10 253), COVID-19-associated deaths more frequently involved Candida (n = 776 [27.1%] vs n = 2432 [23.7%], respectively) and Aspergillus (n = 668 [23.3%] vs n = 1486 [14.5%]) and less frequently involved other specific fungal pathogens. Rates of death due to fungal infection were generally highest in nonwhite and non-Asian populations. Death rates from Aspergillus infections were approximately 2 times higher in the Pacific US census division compared with most other divisions. CONCLUSIONS Deaths from fungal infection increased during 2020-2021 compared with previous years, primarily driven by COVID-19-associated deaths, particularly those involving Aspergillus and Candida. Our findings may inform efforts to prevent, identify, and treat severe fungal infections in patients with COVID-19, especially in certain racial/ethnic groups and geographic areas.

Acute Kidney Failure among Brazilian Agricultural Workers: A Death-Certificate Case-Control Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19116519. [PMID: 35682102 PMCID: PMC9179952 DOI: 10.3390/ijerph19116519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 04/04/2022] [Accepted: 04/07/2022] [Indexed: 02/01/2023]
Abstract
Recent evidence suggests that pesticides may play a role in chronic kidney disease. However, little is known about associations with acute kidney failure (AKF). We investigated trends in AKF and pesticide expenditures and associations with agricultural work in two Brazilian regions with intense use of pesticides, in the south and midwest. Using death certificate data, we investigated trends in AKF mortality (1980–2014). We used joinpoint regression to calculate annual percent changes in AKF mortality rates by urban/rural status and, in rural municipalities, by tertiles of per capita pesticide expenditures. We then compared AKF mortality in farmers and population controls from 2006 to 2014 using logistic regression to estimate odds ratios and 95% confidence intervals adjusted by age, sex, region, education, and race. AKF mortality increased in both regions regardless of urban/rural status; trends were steeper from the mid-1990s to 2000s, and in rural municipalities, they were higher by tertiles of pesticide expenditures. Agricultural workers were more likely to die from AKF than from other causes, especially at younger ages, among females, and in the southern municipalities. We observed increasing AKF mortality in rural areas with greater pesticide expenditures and an association of AKF mortality with agricultural work, especially among younger workers.

Rural-Urban Differences in Maternal Mortality Trends in the United States, 1999-2017: Accounting for the Impact of the Pregnancy Status Checkbox. Am J Epidemiol 2022; 191:1030-1039. [PMID: 35020799 DOI: 10.1093/aje/kwab300] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 12/20/2021] [Accepted: 12/30/2021] [Indexed: 11/13/2022] Open
Abstract
It has been difficult to measure rural-urban differences in maternal mortality ratios (MMRs) in the United States in recent years because of the incremental adoption of a pregnancy status checkbox on the standard US death certificate. Using 1999-2017 mortality and birth data, we examined the impact of the pregnancy checkbox on MMRs according to urbanicity of residence (large urban area, medium/small urban area, or rural area), using log-binomial regression models to predict trends that would have been observed if all states had adopted the checkbox as of 1999. Implementation of the checkbox resulted in an average estimated increase of 7.5 maternal deaths per 100,000 live births (95% confidence interval (CI): 6.3, 8.8) in large urban areas (a 76% increase), 11.6 (95% CI: 9.6, 13.6) in medium/small urban areas (a 113% increase), and 16.6 (95% CI: 12.9, 20.3) in rural areas (a 107% increase), compared with MMRs prior to the checkbox. Assuming that all states had the checkbox as of 1999, demographic-factor-adjusted predicted MMRs increased in rural areas, declined in large urban areas, and did not change in medium/small urban areas. However, trends and urban-rural differences were substantially attenuated when analyses were limited to direct/specific causes of maternal death, which are probably subject to less misclassification. Accurate ascertainment of maternal deaths, particularly in rural areas, is important for reducing disparities in maternal mortality.

Factors associated with the reporting of Down syndrome as the underlying cause of death on US death certificates. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2022; 66:454-470. [PMID: 35191108 PMCID: PMC9018509 DOI: 10.1111/jir.12926] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 02/08/2022] [Accepted: 02/09/2022] [Indexed: 05/03/2023]
Abstract
BACKGROUND Efforts aimed at preventing premature mortality for people with Down syndrome are hindered by the practice of reporting disability as the underlying cause of death. Prior research suggests this form of diagnostic overshadowing may be the result of increased uncertainty surrounding the death. METHODS This study uses bivariable analysis and multivariable logistic regression models to investigate associations between sociodemographic characteristics, comorbidities, and death context and processing characteristics with the reporting of Down syndrome as the underlying cause of death in 2005-2017 US Multiple Cause of Death data files. RESULTS The reporting of Down syndrome as the underlying cause of death was associated with characteristics indicative of an increased amount of uncertainty surrounding the death. Results also suggest other mechanisms may inform inaccurate reporting, such as racial bias, and the continued conflation of disability and health. CONCLUSIONS Medical personnel certifying death certificates should strive for accuracy when reporting the causes of death. To ensure this outcome, even in the midst of increased uncertainty, Down syndrome should not be reported as the underlying cause of death unless the decedent was diagnosed with Alzheimer's disease or unspecified dementia. Future research should further explore the possibility that increased death certification errors for adults with Down syndrome, or other developmental disabilities, are associated with racial bias.

Concordance of Data About Sex From Electronic Health Records and the National Death Index: Implications for Transgender Populations. Epidemiology 2022; 33:383-385. [PMID: 35067566 PMCID: PMC8986558 DOI: 10.1097/ede.0000000000001460] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/28/2022]
Abstract
BACKGROUND Transgender individuals have greater health risks than cisgender individuals, which may bode for greater mortality. However, research is limited by lack of gender identity information at the time of death. Novel opportunities to combine administrative data with National Death Index (NDI) data may facilitate mortality research about transgender populations, but binary measures of sex and gender may pose problems for analyses. This study explored differences in sex recorded in Veterans Health Administration (VHA) electronic health record (EHR) and NDI data between transgender and cisgender decedents. METHODS We used VHA EHR data from fiscal years 2000-2016 to identify deaths among a sample of transgender and cisgender patients. We cross-tabulated sex recorded in the NDI with EHR-based sex from VHA EHR data. We extracted data in 2018 and conducted analyses in 2020. RESULTS Death occurred for 1109 transgender patients and 7757 cisgender patients. For cisgender decedents, EHR-based sex and NDI-based sex were 100% concordant. For transgender decedents, 46 (4%) were discordant between data sources. Of transgender decedents with female EHR-based sex (n = 259), 17% were indicated as male in NDI data; of those with male EHR-based sex (n = 850), 0.2% were indicated as female in NDI data. CONCLUSIONS Data linkage between EHR and the NDI can facilitate transgender mortality research, but examining mortality specific to various transgender identities remains difficult. Improved documentation of sex and gender is needed within US mortality surveillance.

How Many Cancer Patients Need Palliative Care? A Population-Based Study. J Pain Symptom Manage 2022; 63:468-475. [PMID: 34995682 DOI: 10.1016/j.jpainsymman.2021.12.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Revised: 12/23/2021] [Accepted: 12/26/2021] [Indexed: 11/19/2022]
Abstract
BACKGROUND The number of cancer patients potentially amenable to palliative care is conventionally estimated from cancer deaths, as reported in the death certificates. However, a more representative population should also include cancer patients who die from causes other than cancer, as they may develop other life-limiting chronic conditions leading to terminal prognosis. AIM This study aimed at refining the assessment of the number of cancer patients potentially in need of palliative care, by linked hospital and death data. DESIGN Retrospective study. SETTING/PARTICIPANTS Residents in the Emilia Romagna Region in Italy, who died between 2009 and 2017. RESULTS We identified a potential palliative care population of 157,547 cancer patients. The use of different administrative data sources enhanced the sensitivity of our selection. Starting from a standard estimate of 129,212 patients based on cancer as the primary cause of death, we showed that the additional use of hospital records identified a further 11.4% of possible palliative care patients 14,687. Also considering cancer as secondary cause of death, the estimate further increased by 10.6% (13,648 new cases). Notably, the proportion of cancer patients selected by the additional data sources were characterized by more advanced age and higher prevalence of comorbidity. CONCLUSION Healthcare services addressing the issue of estimating palliative care needs of cancer patients at a population level should consider that relying on the death certificate alone may lead to underestimating these needs of about 22%.

A Typology of COVID-19 Data Gaps and Noise From Long-Term Care Facilities: Approximating the True Numbers. Gerontol Geriatr Med 2022; 8:23337214221079176. [PMID: 35224140 PMCID: PMC8864231 DOI: 10.1177/23337214221079176] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/03/2022] Open
Abstract
Although there is agreement that COVID-19 has had devastating impacts in long-term care facilities (LTCFs), estimates of cases and deaths have varied widely with little attention to the causes of this variation. We developed a typology of data vulnerabilities and a strategy for approximating the true total of COVID-19 cases and deaths in LTCFs. Based on iterative qualitative consensus, we categorized LTCF reporting vulnerabilities and their potential impacts on accuracy. Concurrently, we compiled one dataset based on LTCF self-reports and one based on confirmatory matching with California’s COVID-19 databases, including death certificates. Through March 2021, Alameda County LTCFs reported 6663 COVID-19 cases and 481 deaths. In contrast, our confirmatory matching file includes 5010 cases and 594 deaths, corresponding to 25% fewer cases but 23% more deaths. We argue that the higher (self-report) case total approximates the lower bound of true COVID-19 cases, and the higher (confirmed match) death total approximates the lower bound of true COVID-19 deaths, both of which are higher than state and federal counts. LTCFs other than nursing facilities accounted for 35% of cases and 29% of deaths. Improving the accuracy of COVID-19 figures, particularly across types of LTCFs, would better inform interventions for these vulnerable populations.

Does the Application of International Classification of Disease Codes for the Cause of Death on Death Certificates Reduce Garbage Codes? INQUIRY : A JOURNAL OF MEDICAL CARE ORGANIZATION, PROVISION AND FINANCING 2022; 59:469580221081433.

Abstract
INTRODUCTION This study aimed to determine if applying International Classification of Diseases (ICD) disease codes directly as the cause of death (COD) on death certificates (DCs) instead of writing or typing the COD could reduce the use of garbage codes. METHODS Beginning in April of 2016, a documentation process change was made, retiring the process of hand-writing or typing the COD onto DCs to directly applying ICD disease codes that were registered during the patient's course of treatment. The DCs issued at the emergency department (ED) 1 year before (Pre-code group) and after (Code group) applying ICD disease codes directly on DCs was instituted were retrospectively analyzed. The occurrence of garbage codes along with other major and minor errors was compared between the two groups. The investigation and judgment of errors were performed by four emergency physicians. RESULTS The overall garbage code occurrence in the Code group (25%) was significantly lower than that in the Pre-code group (49%). Fewer garbage codes were used in the Code group with an average of .5 in the Pre-code group and .3 in the Code group. No significant difference was identified in major error occurrences except for in the garbage codes. Minor errors were more common in the Pre-code group than in the Code group. CONCLUSION The overall use of garbage codes on DCs could be reduced by changing the process by which physicians complete DCs, that is, the application of documenting ICD disease codes directly as the COD on DCs.

Abstract
BACKGROUND Correct certification of causes of death by physicians according to International Classification of Diseases (ICD) rules is essential to generate mortality statistics of the quality needed to guide public health policy debates and reliably monitor the impact of health interventions. Several efforts to train doctors have been undertaken in the Philippines to improve Medical Certification of Causes of Death (MCCOD). However, there is very little evidence about the long-term effects of training interventions for medical certification. OBJECTIVE To test whether there were measurable long-term impacts of this large-scale training intervention for improving medical certification and reducing different types of certification errors. METHOD We assessed the quality of 2100 MCCOD completed before face-to-face training with those written by the same doctors 6 months after the training. An assessment tool was used to evaluate the quality of MCCOD. RESULTS Less than 1% of the 2100 MCCOD assessed prior to the training were completely error-free, increasing to 19.2% 6 months after the training. On average, the number of errors per certificate fell from 2.2 pre-training to 1.3, six months after training. Importantly, there was a 38% decrease in writing ill-defined causes on the last line, which is particularly important for the policy utility of data. CONCLUSION Training doctors in correct medical certification can have a long-term impact on medical certification practices. IMPLICATIONS Shorter, more focused, trainings that address the most common medical certification errors could have an even greater impact on medical certification practices.

Respiratory syncytial virus-associated deaths in the United States according to death certificate data, 2005 to 2016. Health Sci Rep 2021; 4:e428. [PMID: 34754948 PMCID: PMC8562311 DOI: 10.1002/hsr2.428] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 09/20/2021] [Accepted: 09/27/2021] [Indexed: 11/08/2022] Open
Abstract
BACKGROUND AND AIMS In the United States, respiratory infections due to respiratory syncytial virus (RSV) cause an estimated 57 000 hospitalizations annually among children aged <5 years and 177 000 hospitalizations among adults aged ≥65 years. RSV-associated deaths are less well described. It will be important to establish a baseline of RSV-coded deaths prior to the introduction of vaccines, immunoprophylaxis products, and anti-viral therapies currently in development. METHODS US death certificate data for all ages from 2005 through 2016 were compiled through the National Center for Health Statistics. Deaths with International Classification of Diseases codes of J12.1 (RSV-pneumonia), J20.5 (RSV-bronchitis), or J21.0 (RSV-bronchiolitis) assigned as either the underlying cause of death or a contributing cause of death were considered "RSV-associated" for this analysis. RESULTS Among 30.5 million deaths, 1001 (.003%) were assigned an RSV-associated cause of death as follows: 697 (69.6%) RSV-pneumonia, 277 (27.7%) RSV-bronchiolitis, 17 (1.7%) RSV-bronchitis, and 10 (1.0%) with multiple RSV-associated causes. Most deaths were among children <5 (47.8%) and adults ≥50 (40.4%) years of age. Almost half (46.8%) had an RSV-associated cause as the primary underlying cause of death. The average annual number of RSV-associated deaths did not significantly change among those aged <5 and 5 to 49 years. However, RSV-pneumonia deaths among adults aged ≥50 years increased from 17.6 in 2005 to 2012 to 57.3 in 2013 to 2016 (P value <.0001). CONCLUSIONS From 2005 to 2016, the number of recorded RSV-associated deaths increased, primarily due to greater RSV-associated pneumonia deaths among older adults since 2013. The reasons for this increase are not clear but likely reflect increased testing for RSV among adults. The number of RSV-associated deaths according to death certificates compared with estimates derived from active, laboratory-confirmed surveillance and models using hospital administrative data suggests that counts from death certificates are a large underestimation, particularly among adults.

A national study of epilepsy-related deaths in Scotland: Trends, mechanisms, and avoidable deaths. Epilepsia 2021; 62:2667-2684. [PMID: 34537957 DOI: 10.1111/epi.17065] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Revised: 08/30/2021] [Accepted: 08/30/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE This study was undertaken to investigate the trends and mechanisms of epilepsy-related deaths in Scotland, highlighting the proportion that were potentially avoidable. METHODS This was a retrospective observational data-linkage study of administrative data from 2009-2016. We linked nationwide data encompassing mortality records, hospital admissions, outpatient attendance, antiepileptic drug (AED) prescriptions, and regional primary care attendances. Adults (aged ≥16 years) suffering epilepsy-related death were identified for study using International Classification of Diseases, 10th Revision coding combined with AED prescriptions. We reported epilepsy-related mortality rate (MR), age-specific mortality ratios, multiple cause-of-death frequencies, and the proportion of potentially avoidable deaths (identified as those with an underlying cause listed as avoidable by the Office for National Statistics). RESULTS A total of 1921 epilepsy-related deaths were identified across Scotland; 1185 (62%) decedents were hospitalized for seizures in the years leading up to death, yet only 518 (27%) were seen in a neurology clinic during the same period. MR remained unchanged over time, ranging from 5.9 to 8.7 per 100 000 Scottish population (95% confidence interval [CI] = -.05 to .66 per 100 000 for annual change in MR). Mortality ratios were significantly increased in young adults aged 16-54 years (2.3, 95% CI = 1.8-2.8), peaking at age 16-24 years (5.3, 95% CI = 1.8-8.8). Sudden unexpected death in epilepsy (SUDEP) constituted 30% of the 553 young adult epilepsy-related deaths, with several other non-SUDEP fatal mechanisms identified including aspiration pneumonia, cardiac arrest, AED or narcotic poisoning, drowning, and alcohol dependence. Seventy-six percent of young adult epilepsy-related deaths were potentially avoidable. SIGNIFICANCE Epilepsy-related deaths are a major public health problem in Scotland, given that they are not reducing, people are dying young, and many deaths are potentially avoidable. SUDEP is only one of several important mechanisms by which epilepsy-related deaths are occurring in young adults. Services may need to be re-evaluated to improve specialist referral following seizure-related hospital admissions.

Abstract
Background: Dementia is associated with increased mortality. However, it is not clear whether causes of death in people with dementia have changed over time. Objective: To investigate if causes of death changed over time in people with dementia compared to the general elderly population. Methods: We included longitudinal data from nationwide registries on all Danish residents aged≥65 years to 110 years who died between 2002 to 2015. We assessed the annual frequency of dementia-related deaths (defined as a dementia diagnosis registered as a cause of death) and of underlying causes of death in people registered with dementia compared to the general elderly population. Results: From 2002 to 2015, 621,826 people died, of whom 103,785 were diagnosed with dementia. During this period, the percentage of dementia-related deaths increased from 10.1% to 15.2% in women, and from 6.3% to 9.5% in men in the general elderly population. From 2002 to 2015, dementia became the leading, registered underlying cause of death in people diagnosed with dementia. Simultaneously, a marked decline in cardiovascular and cerebrovascular deaths was observed in people with and without dementia. Conclusion: This is the first study to investigate if the causes of death change over time in people diagnosed with dementia compared with the general elderly population. The increase in the registration of dementia as an underlying cause of death could reflect increasing awareness that dementia is fatal.

Abstract
This article explores the emergence and development of Death Certificates as a means of establishing the cause of death for individuals and populations. The difficulty in choosing which disease caused death when several are described on the Certificate explains why the number of COVID-19-related deaths has been difficult to determine. This problem also draws attention to the dominant biomedical explanation for the cause of death that both promote and circumscribe what can be recognised as a valid cause.

Cancer incidence and mortality in Zhejiang Province, Southeast China, 2016: a population-based study. Chin Med J (Engl) 2021; 134:1959-1966. [PMID: 34334631 PMCID: PMC8382332 DOI: 10.1097/cm9.0000000000001666] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Indexed: 11/29/2022] Open
Abstract
BACKGROUNDS Cancer is one of the main causes of death worldwide, seriously threatening human health and life expectancy. We aimed to analyze the cancer incidence and mortality rates during 2016 in Zhejiang Province, Southeast China. METHODS Data were collected from 14 population-based cancer registries across Zhejiang Province of China. Cancer incidence and mortality rates stratified by sex and region were analyzed. The crude rate, age-standardized rate, age-specific and region-specific rate, and cumulative rate were calculated. The proportions of 10 common cancers in different groups and the incidence and mortality rates of the top five cancers in different age groups were also calculated. The Chinese national census of 2000 and the world Segi population was used for calculating the age-standardized incidence and mortality rates. RESULTS The 14 cancer registries covered a population of 14,250,844 individuals, accounting for 29.13% of the population of Zhejiang Province. The total reported cancer cases and deaths were 55,835 and 27,013, respectively. The proportion of morphological verification (MV%) was 78.95% of the population, and percentage of incident cases identified through death certificates only (DCO%) was 1.23% with a mortality-to-incidence ratio (M/I ratio) of 0.48. The crude incidence rate in Zhejiang cancer registration areas was 391.80/105; the age-standardized incidence rate of the Chinese standard population (ASIRC) and the age-standardized incidence rate of the world standard population (ASIRW) were 229.76/105 and 220.96/105, respectively. The incidence rate in men was higher than that in women. The incidence rate increased rapidly after 45 years of age and peaked in individuals aged 80 to 84 years. The top 10 incidence rates of cancers were lung cancer, female breast cancer, thyroid cancer, colorectal cancer, stomach cancer, liver cancer, prostate cancer, cervical cancer, esophageal cancer, and pancreatic cancer (from highest to lowest). The crude mortality rate in Zhejiang cancer registration areas was 189.55/105; the age-standardized mortality rate of the Chinese standard population (ASMRC) and the age-standardized mortality rate of the world standard population (ASMRW) were 94.46/105 and 93.42/105, respectively. The mortality rate in men was higher than that in women, and the male population in rural areas was higher than that in urban areas. The cancer mortality rate increased rapidly after 50 years of age and peaked in individuals aged 85+ years. The top 10 mortality rates of cancers were lung cancer, liver cancer, stomach cancer, colorectal cancer, pancreatic cancer, esophageal cancer, female breast cancer, prostate cancer, lymphoma, and leukemia (from highest to lowest). CONCLUSIONS Lung cancer, female breast cancer, thyroid cancer, colorectal cancer, prostate cancer, liver cancer, and stomach cancer were the most common cancers in Zhejiang Province. Effective prevention and control measures should be established after considering the different characteristics of cancers in urban and rural areas.

Early neonatal mortality trend in adolescent pregnant women in the State of São Paulo, Brazil, from 1996 to 2017. Transl Pediatr 2021; 10:1573-1585. [PMID: 34295772 PMCID: PMC8261576 DOI: 10.21037/tp-20-438] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Accepted: 04/05/2021] [Indexed: 11/06/2022] Open
Abstract
BACKGROUND The Infant mortality rate indicates the quality of life of a population. Infant mortality has two important components: neonatal mortality, divided into early and late and post-neonatal mortality. The more developed a country is and the greater its population's well-being, the greater the weight of the neonatal component on infant mortality. In addition several factors may determine or be associated with the occurrence of infant deaths including maternal age. The teenage pregnancy rates in Latin America and the Caribbean remain the second highest in the world, In Brazil, between 2010 and 2015, for every thousand adolescents between 15 and 19 years old, about 69 became pregnant and gave birth to their babies. Thus, the objective of this study is to evaluate the trend of Early Neonatal Mortality Rates in children of pregnant adolescents, which occurred in the period 1996-2017, in the state of São Paulo, Brazil, according to the maternal age group. METHODS This is an ecological study of time series using official mortality data obtained from the Mortality Information System and live birth data obtained from the Live Birth Information System. Deaths of newborns aged between zero and six complete days were collected by place of residence. The trends in rates per 1,000 live births were calculated by Prais-Winsten regression, obtaining their annual percentage change (VPA) and the respective 95% confidence intervals, analyzed by age group. All analyzes were processed using the STATA 15.1 software. RESULTS In the state of São Paulo, between 1996 and 2017, 16,161 deaths were reported in children from zero to six days old and 2,320,584 live births in mothers aged 10-19 years, living in the state of São Paulo, Brazil. Of this total, it was observed that the early neonatal mortality rate decreased until the year 2005-2006, remained stationary after, and was higher in newborns of mothers aged 10-14 years (13.18 per 1,000) compared to mothers between 15-19 years (6.75 per 1,000). CONCLUSIONS In conclusion, although the early neonatal mortality rate showed a significant decreasing trend until approximately 2005, it remained stables after that.

Abstract
Introduction Vital status is of central importance to hospital clinical research. However, hospital information systems record only in-hospital death information. Recently, the French government released a publicly available dataset containing death-certificate data for over 25 million individuals. The objective of this study was to link French death certificates to the Bordeaux University Hospital records to complete the vital status information. Materials and Methods Our linkage strategy was composed of a search engine to reduce the number of comparisons and machine-learning algorithms. The overall pipeline was evaluated by assembling a file containing 3,565 in-hospital deaths and 15,000 alive persons. Results The recall and precision of our linkage strategy were 97.5% and 99.97% for the upper threshold and 99.4% and 98.9% for the lower threshold, respectively. Conclusion In this study, we demonstrated the feasibility of accurately linking hospital records with death certificates using a search engine and machine learning.

Abstract
Background Death registration provides an opportunity for the legal documentation of death of persons. Documentation of deaths has several implications including its use in the recovery of inheritance and insurance benefits. It is also an important input for construction of life tables which are crucial for national planning. However, the registration of deaths is poor in several countries including Nigeria. Objective This paper describes the performance of death registration in Nigeria and factors that may affect its performance. Methods We conducted a systematic literature review of death registration completeness in Nigeria to identify, characterize issues as well as challenges associated with realizing completeness in death registration. Results Only 13.5% of deaths in Nigeria were registered in 2007 which regressed to 10% in 2017. There was no data reported for Nigeria in the World Health Organization database between 2008 and 2017. The country scored less than 0.1 (out of a maximum of 1) on the Vital Statistics Performance Index. There are multiple institutions with parallel constitutional and legal responsibilities for death registration in Nigeria including the National Population Commission, National Identity Management Commission and Local Government Authorities, which may be contributing to its overall poor performance. Conclusions We offer proposals to substantially improve death registration completeness in Nigeria including the streamlining and merger of the National Population Commission and the National Identity Management Commission into one commission, the revision of the legal mandate of the new agency to mainly coordination and establishment of standards. We recommend that Local Government authorities maintain the local registries given their proximity to households. This arrangement will be enhanced by increased utilization of information and communications technology in Civil Registration and Vital Statistics processes that ensure records are properly archived.

Cystic fibrosis-related mortality trends in Brazil for the 1999-2017 period: a multiple-cause-of-death study. J Bras Pneumol 2021; 47:e20200166. [PMID: 33656158 PMCID: PMC8332834 DOI: 10.36416/1806-3756/e20200166] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Accepted: 06/13/2020] [Indexed: 02/04/2023] Open
Abstract
OBJECTIVE To describe causes of death and mortality data related to cystic fibrosis (CF) using a multiple-cause-of-death methodology. METHODS Annual mortality data for the 1999-2017 period were extracted from the Brazilian National Ministry of Health Mortality Database. All death certificates in which category E84 (CF) of the ICD-10, was listed as an underlying or associated cause of death were selected. Epidemiological and clinical data were described, and standardized mortality rates were calculated per year and for the 2000-2017 period. A joinpoint regression analysis was performed to detect changes in the mortality rates during the study period. RESULTS Overall, 2,854 CF-related deaths were identified during the study period, ranging from 68 in 1999 to 289 in 2017. CF was the underlying cause of death in 83.5% of the death certificates. A continuous upward trend in the death rates was observed, with a significant annual percent change of 6.84% (5.3-8.4%) among males and 7.50% (6.6-8.4%) among females. The median age at death increased from 7.5 years in 1999 to 56.5 years in 2017. Diseases of the respiratory system accounted for 77% of the associated causes in the death certificates that reported CF as the underlying cause of death. CONCLUSIONS A significant and continuous increase in CF-related death rates was found in Brazil in the last years, as well as a concurrent increase in the median age at death.

Abstract
We examined mortality trends of hepatitis C virus (HCV) infection in the United States in 1999-2018 according to the following definitions: HCV as the underlying cause of death (UCOD), HCV mentioned anywhere on the death certificate (mentioned), and HCV recorded in Part 1 of the death certificate. By using entity axis information in mortality multiple-cause files, we ascertained the position of HCV on the death certificate. Joinpoint regression analysis was used to evaluate changes in HCV mortality rates according to the definitions. The age-standardized HCV mortality rates (deaths per 100,000 people) in terms of UCOD, mentioned, and Part 1 were, respectively, 1.36, 2.87 and 1.94, in 1999; increased to 1.90, 5.09 and 2.96 in 2013; and declined to 0.98, 3.77 and 2.29 in 2018. The mentioned/UCOD mortality ratio was 2.11 in 1999 and increased to 3.86 in 2018. The mentioned/Part 1 ratio was almost identical (ie 1.48 in 1999 and 1.65 in 2018). The extent of decline from 2014 to 2018 differed according to the definitions; the annual per cent changes for UCOD, mentioned, and Part 1 were -14.6%, -7.1% and -9.8%, respectively. For the same age group, the baby boomer subcohort 1950-1954 had the highest mortality rates among the subcohorts (1945-1949, 1955-1959 and 1960-1964). HCV mortality according to HCV in Part 1 of the death certificate-the explicit opinion of a certifying physician that HCV played a substantial role and directly caused death-differed from that according to HCV as UCOD and HCV mentioned.

Abstract
BACKGROUND Patients with obstructive lung diseases may be at risk of hospitalization and/or death due to COVID-19. AIM To estimate the frequency of severe COVID-19, and COVID-19-related mortality in a well-defined large population of patients with asthma and chronic inflammatory lung disease (COPD). Further to assess the frequency of asthma and COPD as registered comorbidities at discharge from hospital, and in death certificates. METHODS At the start of the pandemic, the Swedish National Airway Register (SNAR) included 271,404 patients with a physician diagnosis of asthma and/or COPD. In September 2020, after the first COVID-19 wave in Sweden, the database was linked with the National Patient Register (NPR), the Swedish Intensive Care Register and the Swedish Cause of Death Register, which all provide data about COVID-19 based on International Classification of Diseases (ICD-10) codes. Severe COVID-19 was defined as hospitalization and/or intensive care or death due to COVID-19. RESULTS Among patients in SNAR, 0.5% with asthma, and 1.2% with COPD were identified with severe COVID-19. Among patients < 18 years with asthma, only 0.02% were severely infected. Of hospitalized adults, 14% with asthma and 29% with COPD died. Further, of patients in SNAR, 56% with asthma and 81% with COPD were also registered in the NPR, while on death certificates the agreement was lower (asthma 24% and COPD 71%). CONCLUSION The frequency of severe COVID-19 in asthma and COPD was relative low. Mortality for those hospitalized was double as high in COPD compared to asthma. Comorbid asthma and COPD were not always identified among patients with severe COVID-19.

Abstract
Background: Death certificates are considered the most reliable source of information to compare cause-specific mortality across countries. The aim of the present study was to examine death certificates of persons who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to (a) quantify the number of deaths directly caused by coronavirus 2019 (COVID-19); (b) estimate the most common complications leading to death; and (c) identify the most common comorbidities. Methods: Death certificates of persons who tested positive for SARS-CoV-2 provided to the National Surveillance system were coded according to the 10th edition of the International Classification of Diseases. Deaths due to COVID-19 were defined as those in which COVID-19 was the underlying cause of death. Complications were defined as those conditions reported as originating from COVID-19, and comorbidities were conditions independent of COVID-19. Results: A total of 5311 death certificates of persons dying in March through May 2020 were analysed (16.7% of total deaths). COVID-19 was the underlying cause of death in 88% of cases. Pneumonia and respiratory failure were the most common complications, being identified in 78% and 54% of certificates, respectively. Other complications, including shock, respiratory distress and pulmonary oedema, and heart complications demonstrated a low prevalence, but they were more commonly observed in the 30-59 years age group. Comorbidities were reported in 72% of certificates, with little variation by age and gender. The most common comorbidities were hypertensive heart disease, diabetes, ischaemic heart disease, and neoplasms. Neoplasms and obesity were the main comorbidities among younger people. Discussion: In most persons dying after testing positive for SARS-CoV-2, COVID-19 was the cause directly leading to death. In a large proportion of death certificates, no comorbidities were reported, suggesting that this condition can be fatal in healthy persons. Respiratory complications were common, but non-respiratory complications were also observed.

Erroneous Reporting of Deaths Attributed to Pneumonia and Influenza at 2 New York City Teaching Hospitals, 2013-2014. Public Health Rep 2020; 135:796-804.

Abstract
OBJECTIVES Cause-of-death information, reported by frontline clinicians after a patient's death, is an irreplaceable source of public health data. However, systematic bias in cause-of-death reporting can lead to over- or underestimation of deaths attributable to different causes. New York City consistently reports higher rates of deaths attributable to pneumonia and influenza than many other US cities and the country. We investigated systematic erroneous reporting as a possible explanation for this phenomenon. METHODS We reviewed all deaths from 2 New York City hospitals during 2013-2014 in which pneumonia or influenza was reported as the underlying cause of death (n = 188), and we examined the association between erroneous reporting and multiple extrinsic factors that may influence cause-of-death reporting (patient demographic characteristics and medical comorbidities, time and hospital location of death, type of medical provider reporting the death, and availability of certain diagnostic information). RESULTS Pneumonia was erroneously reported as the underlying cause of death in 163 (86.7%) reports. We identified heart disease and dementia as the more likely underlying cause of death in 21% and 17% of erroneously reported deaths attributable to pneumonia, respectively. We found no significant association between erroneous reporting and the multiple extrinsic factors examined. CONCLUSIONS Our results underscore how erroneous reporting of 1 condition can lead to underreporting of other causes of death. Misapplication or misunderstanding of procedures by medical providers, rather than extrinsic factors influencing the reporting process, are key drivers of erroneous cause-of-death reporting.

Abstract
INTRODUCTION 1,5-Anhydroglucitol (1,5-AG) is a biomarker of glucose spikes. To evaluate the effect of acute glucose excursions on cancer death, we clarified the association between 1,5-AG and cancer mortality among Japanese individuals with normal glucose tolerance. RESEARCH DESIGN AND METHODS We measured 1,5-AG in 6783 (2842 men, 3941 women) individuals with normal fasting and 2-hour plasma glucose who received a 75 g oral glucose tolerance test between 1994 and 2012. They were followed for mortality until August 2013. A systematic review of death certificates was used to confirm the cause of death. We divided the participants into four groups according to the quartile of 1,5-AG level at registration. We used Cox regression to clarify the association between 1,5-AG levels and cancer mortality with multivariate adjustment for possible confounders. RESULTS During the follow-up period (median, 10.0 years), 140 men and 109 women died of cancer. The HR for cancer mortality of the lowest quartile group was higher than that of the highest quartile group in men (HR, 2.62; 95% CI, 1.60 to 4.41) and in women (HR, 1.47; 95% CI, 0.88 to 2.47). These associations were not attenuated with further adjustment for HbA1c. CONCLUSIONS 1,5-AG was associated with high risk of cancer mortality in Japanese men after adjustment for HbA1c.

Abstract
BACKGROUND Public health research uses decedents' usual industry and occupation (I&O) from US death certificates to assess mortality incidence and risk factors. Of necessity, such research may exclude decedents with insufficient I&O information, and assume death certificates reflect current (at time of death) I&O. This study explored the demographic implications of such research conditions by describing usual occupation and current employment status among decedents by demographic characteristics in a large multistate data set. METHODS Death certificate occupations classified by Standard Occupational Classification (SOC) (ie, compensated occupation) and other categories (eg, student) for 36 507 decedents (suicide, homicide, other, undetermined intent) age 22+ years from the 2016 National Violent Death Reporting System's (NVDRS) 32 US states were analyzed. Decedents not employed at the time of death (eg, laid off) were identified through nondeath certificate NVDRS data sources (eg, law enforcement reports). RESULTS Female decedents, younger (age < 30 years) male decedents, some non-White racial group decedents, less educated decedents, and undetermined intent death decedents were statistically less likely to be classified by SOC based on death certificates-primarily due to insufficient information. Decedents classified by SOC from death certificates but whose non-death certificate data indicated no employment at the time of death were more often 30+ years old, White, less educated, died by suicide, or had nonmanagement occupations. CONCLUSIONS Whether decedents have classifiable occupations from death certificates may vary by demographic characteristics. Research studies that assess decedents by usual I&O can identify and describe how any such demographic trends may affect research results on particular public health topics.

Abstract
The prognostic relevance of short-term blood pressure (BP) variability in hypertension is not clearly established. We aimed to evaluate the association of short-term BP variability, assessed through ambulatory BP monitoring, with total and cardiovascular mortality in a large cohort of patients with hypertension. We selected 63 910 subjects from the Spanish ABPM Registry from 2004 to 2014, with a median follow-up of 4.7 years. Systolic and diastolic BP SD from 24 hours, daytime, and nighttime, weighted SD (mean of daytime and nighttime SD weighted for period duration), average real variability (mean of differences between consecutive readings), variation independent of the mean, and BP variability ratio (ratio between systolic and diastolic 24-hour SD) were calculated through 24-hour ambulatory BP monitoring performed at baseline. Association with total and cardiovascular mortality (obtained through death certificates) were assessed by Cox regression models adjusted for clinical confounders and BP. Patients who died during follow-up had higher values of BP variability compared with those remaining alive. In fully adjusted models, daytime, nighttime, and weighted SD, systolic and diastolic, as well as diastolic average real variability, were all significantly associated with total and cardiovascular mortality. Hazard ratios for 1 SD increase ranged from 1.05 to 1.09 for total mortality and from 1.07 to 1.12 for cardiovascular mortality. A nighttime systolic SD ≥12 mm Hg was independently associated with total (hazard ratio: 1.13 [95% CI, 1.06-1.21]) and cardiovascular mortality (hazard ratio: 1.21 [95% CI, 1.09-1.36]). We conclude that short-term BP variability is independently associated with total and cardiovascular mortality in patients with hypertension.

Abstract
The validity of data provided by population-based cancer registries (PBCRs) is a key aspect in cancer surveillance. Tracing back cases initially reported by death certificate or death-certificate-notified (DCN) cases, improves data quality and has an especially significant impact on survival estimates. The present study performed in the Mendoza PBCR describes the trace-back procedure of cancer cases notified by death certificate for selected cancers (liver, lung, and stomach cancers) with the aim of reducing the percentage of cases diagnosed by death certificate only (DCO). The study was performed in 2018 using cancers diagnosed between 2006 and 2012 in the framework of a survival project (SURVCAN-3). Among the 822 cases that have been traced back, only 32.1% had an identified source of information. Of these, 70.3% had medical records available for review. Of the reviewed medical records, 86.9% of cancer diagnoses were confirmed. The DCN and DCO cases were much higher among older age groups. With the trace-back, the overall percentage of DCO was reduced from 23.8% to 19.9%. We conclude that DCN trace-back could improve data quality by reducing DCO diagnoses, which directly impacts survival estimates. Trace-back should be performed routinely and in a timely manner.

Abstract
The statistics of causes of death is the informational basis for identifying public health problems. That is why the accurately accounting for mortality from diabetes mellitus, which is a global medical and social problem for society, is important. The study was carried out to analyze the correctness of coding death causes of diabetes mellitus and the frequency of alleged death. MATERIALS AND METHODS The Moscow deceased population database of July 2018 - July 2019 was analyzed. Using the decision tables on codes linkages from ICD-10, incorrect codes for underline cause were established for 342 death cases from diabetes mellitus. Among 43044 cases of cardiovascular death the cases of presumed death from diabetes were detected. The analysis was carried out in the Microsoft Access 2007 software. THE RESULTS In 18.4% of cases, the cause of death from diabetes was encoded incorrectly. If a modification of the underline death cause is assumed due to the mention of certain diseases in any line of the Death Certificate, cases of coding for death from diabetes with wrong fourth character are more often detected when mentioning kidney diseases. If modification of the underline cause is provided for cases when information in the Death Certificate indicates that diabetes has caused the development of some diseases then the largest number of cases with incorrect coding was detected when mentioning circulatory diseases. Only in one medical organization the frequency of incorrect coding is 3.4%, in the rest it varies from 15.4% to 52.2%. Among all death causes, diabetes was only 0.41%. If to add cases of presumptive death from diabetes mellitus, then the proportion of diabetes in the structure of death causes will almost triple and reach up to 1.2%. CONCLUSIONS The quality of diagnosis and coding of death causes from diabetes has not improved in recent years. To increase it, it is advisable to organize and establish the institution of coders. It is advisable to indicate the presence of diabetes mellitus in the Death Certificate without fail and use the information from the diabetes register. It is proposed to encode the death cause from diabetes mellitus with multiple complications use line D in the Death Certificate to indicate damage to various organs and systems if it is necessary.

Mortality due to malnutrition in older adults, Colombia, 2014-2016. BIOMEDICA : REVISTA DEL INSTITUTO NACIONAL DE SALUD 2019; 39:663-672. [PMID: 31860178 PMCID: PMC7363351 DOI: 10.7705/biomedica.4733] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/17/2018] [Accepted: 03/28/2019] [Indexed: 11/23/2022]
Abstract
Introduction: Older people are positioned within the context of public health and nutrition as a vulnerable group. The priorities of the attention programs focus on eating habits and monitoring their nutritional status to improve their vital prognosis. Objective: To estimate the cases of death due to malnutrition of the population over 65 years old in Colombia for 2014 to 2016 to contribute to the analysis and decision-making in health to improve the nutritional situation of this population. Materials and methods: A retrospective descriptive study was carried out analizing death certificates from 2014 to 2016, whose basic cause of death was nutritional deficiencies and anemias. Mortality rates were estimated by sex and department of residence, and distribution frequencies were built based on demographic variables. Results: There were 3,275 deaths due to malnutrition in Colombia for the elderly in the study period (0.5% of total deaths). The mortality rate varied between 5.4 and 108.3 per 100,000 older adults. The highest mortality occurred in those over 80 years of age, especially in men. Conclusion: Caloric protein malnutrition in older adults is the most frequent cause of death due to malnutrition, followed by nutritional anemias. The highest mortality occurs in the age group over 80 years of age and the Amazonas, Guainía and Vaupés departments have the highest rates for all age groups.

Clustering of 27,525,663 Death Records from the United States Based on Health Conditions Associated with Death: An Example of big Health Data Exploration. J Clin Med 2019; 8:jcm8070922. [PMID: 31252579 PMCID: PMC6678953 DOI: 10.3390/jcm8070922] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2019] [Revised: 06/19/2019] [Accepted: 06/21/2019] [Indexed: 12/20/2022] Open
Abstract
Background: Insight into health conditions associated with death can inform healthcare policy. We aimed to cluster 27,525,663 deceased people based on the health conditions associated with death to study the associations between the health condition clusters, demographics, the recorded underlying cause and place of death. Methods: Data from all deaths in the United States registered between 2006 and 2016 from the National Vital Statistics System of the National Center for Health Statistics were analyzed. A self-organizing map (SOM) was used to create an ordered representation of the mortality data. Results: 16 clusters based on the health conditions associated with death were found showing significant differences in socio-demographics, place, and cause of death. Most people died at old age (73.1 (18.0) years) and had multiple health conditions. Chronic ischemic heart disease was the main cause of death. Most people died in the hospital or at home. Conclusions: The prevalence of multiple health conditions at death requires a shift from disease-oriented towards person-centred palliative care at the end of life, including timely advance care planning. Understanding differences in population-based patterns and clusters of end-of-life experiences is an important step toward developing a strategy for implementing population-based palliative care.

[Quality of maternal mortality statistics in Cuba, 2013Qualidade das estatísticas de mortalidade materna em Cuba, 2013]. Rev Panam Salud Publica 2019; 42:e47. [PMID: 31093075 PMCID: PMC6385788 DOI: 10.26633/rpsp.2018.47] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2017] [Accepted: 01/11/2018] [Indexed: 11/24/2022] Open
Abstract
Objetivos Evaluar el grado de integridad del registro estadístico cubano de muertes maternas y la calidad de la clasificación de las causas de muerte recogidas en ese registro. Métodos Se analizó la información de todas las cubanas fallecidas en edad fértil en el año 2013 según el registro continuo de mortalidad de la Dirección de Registros Médicos y Estadísticas de Salud del Ministerio de Salud Pública de Cuba (MINSAP), independientemente de la causa básica de muerte consignada. Cuatro grupos de investigación (nacional, de expertos, provincial y de unidades de salud), con funciones definidas, aplicaron cuatro formularios para determinar si hubo embarazo en el año previo a la defunción, reevaluar si los casos correspondían a una muerte materna y, en ese caso, revisar la clasificación. Resultados Se investigaron las 2 731 mujeres fallecidas en edad reproductiva notificadas en Cuba en el 2013; de ellas las causas de muerte de 2 711 (99,3%) resultaron concluyentes y, de estas, 97 (3,6%) habían tenido un embarazo en el año previo a la defunción. Se encontraron 50 muertes maternas (una más que en el registro continuo) para 2% de error y un factor de ajuste de 1,02. De las 97 muertes estudiadas, solo se reclasificaron 4 casos: 2 muertes maternas y 1 muerte relacionada con el embarazo, el parto y el puerperio, según el registro continuo, que se reclasificaron como muertes directas, y 1 muerte considerada no materna por el registro continuo que se reclasificó como muerte materna tardía, para una concordancia de 95,9%. Conclusiones La información sobre las muertes maternas recogida en el registro continuo de mortalidad del MINSAP tiene un alto nivel de integridad. La calidad de la clasificación de las muertes maternas en ese registro es elevada, al existir muy pocos cambios en la reclasificación de las causas de muerte.

Place of death in a small island state: a death certificate population study. BMJ Support Palliat Care 2019; 10:e30. [PMID: 30659046 DOI: 10.1136/bmjspcare-2018-001631] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2018] [Revised: 11/23/2018] [Accepted: 12/19/2018] [Indexed: 02/05/2023]
Abstract
OBJECTIVES Low/middle-income countries, particularly Small Island Developing States, face many challenges including providing good palliative care and choice in place of care and death, but evidence of the circumstances of dying to inform policy is often lacking. This study explores where people die in Trinidad and Tobago and examines and describes the factors associated with place of death. METHODS A population-level analysis of routinely collected death certificate and supplementary health data where the unit of analysis was the recorded death. We followed the Reporting of Studies Conducted Using Observational Routinely Collected Health Data reporting guidelines, an extension of Strengthening the Reporting of Observational Studies in Epidemiology, on a deidentified data set on decedents (n=10 221) extracted from International Statistical Classification of Diseases version 10 coded death records for the most recent available year, 2010. RESULTS Of all deaths, 55.4% occurred in a government hospital and 29.7% in a private home; 65.3% occurred in people aged 60 years and older. Cardiovascular disease (23.6%), malignancies (15.5%) and diabetes mellitus (14.7%) accounted for over half of all deaths. Dying at home becomes more likely with increasing age (70-89 years (OR 1.91, 95% CI 1.73 to 2.10) and 90-highest (OR 3.63, 95% CI 3.08 to 4.27)), and less likely for people with malignancies (OR 0.85, 95% CI 0.74 to 0.97), cerebrovascular disease (OR 0.61, 95% CI 0.51 to 0.72) and respiratory disease (OR 0.74, 95% CI 0.59 to 0.91). CONCLUSION Place of death is influenced by age, sex, race/ethnicity, underlying cause of death and urbanisation. There is inequality between ethnic groups regarding place of care and death; availability, affordability and access to end-of-life care in different settings require attention.

Evaluation of Cardiac Complications Following Hemorrhagic Stroke Using 5-Year Centers for Disease Control and Prevention (CDC) Database. J Clin Med 2018; 7:jcm7120519. [PMID: 30563186 PMCID: PMC6307079 DOI: 10.3390/jcm7120519] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2018] [Revised: 11/28/2018] [Accepted: 12/03/2018] [Indexed: 01/13/2023] Open
Abstract
Literature regarding cardiac deaths in hemorrhagic stroke patients is few. The aim of this study was to investigate the incidence and risk factors of cardiac death in hemorrhagic stroke patients. We used the multiple causes of death database from the Centers for Disease Control and Prevention Wide-ranging Online Data of the United States. We identified death certificates from 2006 to 2010 with hemorrhagic stroke (International Classification of Disease, Tenth Revision (ICD-10) code I60-62), or ischemic stroke (ICD-10 code I63), and evaluated the frequency and risk factors of reporting MI (ICD-10 code I20-25) or arrhythmias (ICD-10 code I44-45, I47-49) as the main cause of death in these populations. Over the five-year period, 224,359 death certificates that mentioned hemorrhagic stroke were identified, and the cause of death was MI in 8.95% and arrhythmia in 7.28% patients. With autopsy confirmation, the incidences of MI and arrhythmias in the hemorrhagic stroke group were still lower than the ischemic group. The odds ratio of reporting arrhythmias as a cause of death in hospitalized population was higher. A substantial percentage of hemorrhagic stroke patients had cardiac death. Greater efforts are needed to closely monitor high-risk groups such as females and the elderly.
