Assessing the accuracy of reporting of hypertension on death certificates in Australia.

BACKGROUND: There is insufficient evidence of how accurately hypertension is reported on death certificates, which are the primary evidence of causes of death. This study assesses the accuracy of reporting of hypertension on death certificates of decedents in Australia who previously had their blood pressure measured. METHODS: Blood pressure data from the 2014-15 and 2017-18 National Health Surveys were linked to death registration data from July 2015-December 2021 (average 3.3 years from survey to death). The percentage of decedents with hypertension reported on the death certificate was calculated according to blood pressure level and previous diagnosis of hypertension. RESULTS: Hypertension was reported on the death certificate of 20.2% (95% confidence interval 12.1-28.3%) of decedents who had very high to severe blood pressure (160/100 mmHg and above), 14.5% (10.3-18.8%) who had high blood pressure (140/90 mmHg to less than 160/100 mmHg), 14.1% (10.8%-17.4%) who had normal to high blood pressure (less than 140/90 mmHg) and who took hypertension medication, and 17.8% (13.6-22.0%) who had been diagnosed with hypertension. Where the decedent had very high to severe blood pressure, hypertension was reported for 27.9% (14.1-41.8%) of deaths if they had been diagnosed with hypertension and 21.7% (9.6-33.7%) where another cardiovascular disease was reported on the death certificate. CONCLUSIONS: Hypertension mortality in Australia is only reported for a minority of deaths of people with high or very high to severe blood pressure; this is also found for those with a prior diagnosis of hypertension.

Deaths related to post-COVID in Italy: a national study based on death certificates.

Introduction: SARS-CoV-2 infection has been associated with the onset or persistence of symptoms in the long-term after the acute infection is resolved. This condition known as Post-COVID, might be particularly severe and potentially life-threatening. However, little is known on the impact of post-COVID condition on mortality. Aim of the present study is to assess and quantify Post-COVID deaths in Italy in years 2020 and 2021, based on an analysis of death certificates. Methods: Data from the Italian National Cause of Death Register were analyzed. ICD-10 code U09.9, released by the World Health Organization in September 2020, was used to identify the 'Post-COVID' condition. Numbers of post-COVID deaths from October 2020 to December 2021 were analyzed. Rates of post-COVID deaths were calculated for the year 2021. Results: Between October 2020 and December 2021, 4,752 death certificates reporting post-COVID condition were identified. Of these, 14.9% (n = 706) occurred between October and December 2020 and 85.1% (n = 4,046) in 2021. In 46.0% of post-COVID-related deaths, the underlying cause of death was COVID-19. Other frequent underlying causes were heart disease (14.3% of cases), neoplasms (9.2%), cerebrovascular diseases (6.3%) and Alzheimer's disease and other dementias (5.5%). The mortality rate related to post-COVID conditions in year 2021 was 5.1 deaths per 100 thousand inhabitants and it increased with increasing age. Men showed a higher mortality rate than women (4.3 deaths per 100 thousand in women and 6.0 deaths per 100 thousand in men). Discussion: Post-COVID conditions contributed to a substantial number of deaths in Italy. Strategies to identify the population at risk of severe long-term consequences of SARS-CoV-2 infection and interventions aimed at reducing this risk must be developed.

Looking at the future of the medical certification of cause of death (MCCD) in England and Wales.

Internationally, the quality of death certification is poor although there are multiple efforts underway to improve the process. In England, a new medical certification system has been proposed to improve the quality of data. We surveyed general practitioners (n = 95) across the West Yorkshire area of England to appraise their views regarding whether further possible changes to the death certification system could promote their quality.

Death on the permafrost: Revisiting the 1918-20 influenza pandemic in Alaska using death certificates.

The 1918-20 influenza pandemic devastated Alaska's Indigenous populations. We report on quantitative analyses of pandemic deaths due to pneumonia and influenza (P&I) using information from Alaska death certificates dating between 1915 and 1921 (n=7,147). Goals include a reassessment of pandemic death numbers, analysis of P&I deaths beyond 1919, estimates of excess mortality patterns overall and by age using intercensal population estimates based on Alaska's demographic history, and comparisons between Alaska Native (AN) and non-AN residents. Results indicate that ANs experienced 83% of all P&I deaths and 87% of all-cause excess deaths during the pandemic. AN mortality was 8.1 times higher than non-AN mortality. Analyses also uncovered previously unknown mortality peaks in 1920. Both subpopulations showed characteristically high mortality of young adults, possibly due to imprinting with the 1889-90 pandemic virus, but their age-specific mortality patterns were different: non-AN mortality declined after age 25-29 and stayed relatively low for the elderly, while AN mortality increased after age 25-29, peaked at age 40-44, and remained high up to age 64. This suggests a relative lack of exposure to H1-type viruses pre-1889 among AN persons. In contrast, non-AN persons, often temporary residents, may have gained immunity before moving to Alaska.

Trends in cause-specific mortality among persons with Alzheimer's disease in South Carolina: 2014 to 2019.

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.

Understanding the Fluctuations in Korea's Suicide Rates: A Change-Point Analysis and Interrupted Time Series Analysis.

BACKGROUND: Korea has witnessed significant fluctuations in its suicide rates in recent decades, which may be related to modifications in its death registration system. This study aimed to explore the structural shifts in suicide trends, as well as accidental and ill-defined deaths in Korea, and to analyze the patterns of these changes. METHODS: We analyzed age-adjusted death rates for suicides, deaths due to transport accidents, falls, drowning, fire-related incidents, poisonings, other external causes, and ill-defined deaths in Korea from 1997 to 2021. We identified change-points using the 'breakpoints' function from the 'strucchange' package and conducted interrupted time series analyses to assess trends before and after these change-points. RESULTS: Korea's suicide rates had three change-points in February 2003, September 2008, and June 2012, characterized by stair-step changes, with level jumps at the 2003 and 2008 change-points and a sharp decline at the 2012 change-point. Notably, the 2003 and 2008 spikes roughly coincided with modifications to the death ascertainment process. The trend in suicide rates showed a downward slope within the 2003-2008 and 2008-2012 periods. Furthermore, ill-defined deaths and most accidental deaths decreased rapidly through several change-points in the early and mid-2000s. CONCLUSION: The marked fluctuations in Korea's suicide rate during the 2000s may be largely attributed to improvements in suicide classification, with potential implications beyond socio-economic factors. These findings suggest that the actual prevalence of suicides in Korea in the 2000s might have been considerably higher than officially reported.

Ischemic heart disease-related mortality in Brazil, 2006 to 2020. A study of multiple causes of death.

CONTEXT: Both the aging of the population and the increase in noncommunicable diseases may influence the progression and outcomes culminating in death, changing the evolution of ischemic heart diseases (IHDs) and their associated causes. Using the multiple causes of death method could help understand the magnitude of these relationships and enable better targeting of investments in health. OBJECTIVES: To evaluate the mortality from IHD in Brazil between 2006 and 2020 using the method of multiple causes and identify differences in the distribution pattern of IHD mortality by sex and geographic region. METHODS: Based on information extracted from death certificates (DCs) obtained from the database of the Department of Informatics of the Unified Health System (DATASUS), we used the multiple causes method to analyze the causes of death associated with IHD when IHD was defined as the underlying cause of death (UC) and the causes of death listed as the UC when IHD was recorded in any other lines of the DC, from 2006 to 2020, in Brazil. Subsequently, the proportion of these causes of death and differences between sexes and geographic regions were evaluated, with statistical relevance analyzed using the chi-square test, and the dependence between factors illustrated using stacked bar charts and small-world network graphs. RESULTS: When IHD was listed as the UC of death, the most frequent associated causes of death were, in descending order of frequency, acute myocardial infarction (AMI), arterial hypertension (AH), chronic ischemic heart disease (CHID), heart failure (HF), and diabetes mellitus (DM). When IHD was mentioned in any line of the DC, the most frequent UCs of death were AMI followed by DM, CIHD, chronic obstructive pulmonary disease (COPD), stroke, dyslipidemia, and, in the year 2020, COVID-19. The most frequent cause of death in women were DM as the UC and associated cause of death, AH as the UC, and CIHD and Alzheimer's disease as associated causes of death, while the most frequent causes of death in men were substance dependence as the UC and associated cause of death, and cancer as an associated cause of death. The most frequent causes of death were DM and stroke in the North and Northeast, dyslipidemia and obesity in the Midwest, Alzheimer's disease in the South and Southeast, and atherosclerotic heart disease (AHD) and COPD in the South. CONCLUSIONS: Several diseases - including AMI, AH, CIHD, HF, and DM - were the most frequent associated causes of death when IHD was recorded as the UC. In contrast, AMI, DM, CIHD, COPD, and stroke were the most frequent UCs when IHD was listed as an associated cause of death. The degree of these associations varied between sexes and geographic regions.

The rise of home death in the COVID-19 pandemic: a population-based study of death certificate data for adults from 32 countries, 2012-2021.

Background: During the coronavirus 2019 disease (COVID-19) pandemic, health systems had to respond to the needs of COVID-19 patients, while caring for patients with other life-threatening conditions. Pandemics, such as the COVID-19 pandemic, stir global health and mortality patterns. This is likely to include trends in dying places. In this paper, we examine trends in place of death for adults in 32 countries, comparing the initial COVID-19 pandemic years (2020-2021) with the eight years before the pandemic (2012-2019). Methods: Data on place of death for all adults (18 years and over) that died from 1 January 2012 to 31 December 2021 were requested (47 countries approached, 32 included). The classification of place of death varied widely between countries. "Home" was the most common category, the remaining category groups comprised "hospital or health institution", "other defined", and "ill-defined". We analysed place of death data in an aggregate form, by sex, age group, and selected underlying causes of death (cancer, dementia, and COVID-19). Findings: The study included 100.7 million people (51.5% male, 68.0% with ≥70 years), 20.4% died from cancer and 5.8% from dementia; 30.8% of deaths took place at home. The percentage of home deaths rose from 30.1% in 2012-2013 to 30.9% in 2018-2019 and further to 32.2% in the pandemic (2020-2021). Home deaths increased during the pandemic in 23 countries. In most countries the rise was greater in women and cancer; age differences were not consistent. Interpretation: Our study shows that there was a rise in home deaths during the pandemic, but with variability across countries, sex, age, and causes of death. The sex difference observed in most countries may have several explanations, including more engagement of women in discussions about end of life care planning and hospital admission avoidance. A higher rise of home deaths among people dying of cancer may be explained by the more predictable disease trajectory compared to non-malignant conditions, as well as earlier and better integrated palliative care. Funding: This work is part of the EOLinPLACE Project, which has received funding from the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme (grant agreement No 948609).

Multicausal analysis of mortality due to diabetes mellitus in Spain, 2016-2018.

OBJECTIVES: This study aimed to assess multicausal mortality due to diabetes from 2016-2018 in Spain. Specific objectives were to quantify the occurrence of diabetes as an underlying cause or as any registered cause on the death certificate. MATERIALS AND METHODS: A cross-sectional descriptive study taking a multicausal approach. RESULTS: Diabetes appears as an underlying cause of 2.3% of total deaths in Spain, and as any cause in 6.2%. In patients in whom Diabetes appears as an underlying cause on the death certificates, the 15 most frequent immediate causes are cardiovascular diseases in men(prevalence ratio 1,59)and women (PR1,31). In men, the causes associated with diabetes as any cause were skin diseases(prevalence ratio 1.33), followed by endocrine diseases(prevalence ratio 1.26)and genitourinary diseases (prevalence ratio1.14). In women, the causes associated with the presence of diabetes as any cause were endocrine (prevalence ratio 1.13)and genitourinary (prevalence ratio 1.04)diseases. CONCLUSIONS: In patients in whom diabetes appears as an underlying cause on the death certificates, the 15 most frequent immediate causes are cardiovascular diseases. In men, the causes associated with the presence of diabetes as any cause of death are skin, endocrine and genitourinary diseases. In women, the causes associated with diabetes as any cause are endocrine and genitourinary.

EOLinPLACE: an international research project to reform the way dying places are classified and understood.

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. Trial registration: Research Registry UIN 9213.

Need for Improved Timeliness of Reporting on Drug Overdose Fatalities: The HEALing Communities Study.

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.

Frequency and types of errors in clinician-composed death certificates for patients with or without autopsy in a hospital population.

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.

Mortality trends and sociodemographic factors associated with early death in sickle cell disease patients in the state of São Paulo / Tendência da mortalidade e fatores sociodemográficos associados à morte precoce em pacientes com doença falciforme no estado de São Paulo

ABSTRACT Objective: To estimate trends in mortality rate and average age of death, and identify sociodemographic factors associated with early death in patients with sickle cell disease (SCD). Methods: An ecological and cross-sectional study was conducted using data from the Mortality Information System. All deaths of patients residing in the state of São Paulo from 1996 to 2015 with at least one International Disease Code for SCD in any field of the death certificate were included. Simple linear regression was used to estimate trends. The Log-rank test and multiple Cox regression were used to identify factors associated with early death. Results: The age-standardized mortality rate per million inhabitants increased by 0.080 per year (R2=0.761; p<0.001). When the events were stratified by age at death, the increase was 0.108 per year for those occurring at age 20 years or older, (R2=0.789; p<0.001) and 0.023 per year for those occurring before age 20 years old (R2=0.188; p=0.056). The average age at death increased by 0.617 years (7.4 months) per year (R2=0.835; p<0.001). Sociodemographic factors associated with early death identified were male gender (hazard ratio — HR=1.30), white race (HR=1.16), death occurring in the hospital (HR=1.29), and living in the Greater São Paulo (HR=1.13). Conclusions: The mortality rate and the average age of death in patients with SCD have increased over the last two decades. Sociodemographic factors such as gender, race, place of occurrence, and residence were found to be associated with early death.

RESUMO Objetivo: Estimar as tendências da taxa de mortalidade e da idade média de morte e identificar os fatores sociodemográficos associados ao óbito precoce em pacientes com doença falciforme (DF). Métodos: Estudo ecológico e transversal realizado com dados do Sistema de Informações sobre Mortalidade. Foram incluídos todos os eventos de óbitos de pacientes residentes no estado de São Paulo de 1996 a 2015, que continham pelo menos um Código Internacional de Doenças para DF, em qualquer campo do atestado de óbito. As tendências foram estimadas por meio da regressão linear simples. Para a identificação dos fatores associados ao óbito precoce, foram realizadas análises de sobrevida, por meio da regressão de Cox simples e múltipla. Resultados: A taxa de mortalidade, padronizada pela idade, por milhão de habitantes, aumentou 0,080 ao ano (R²=0,761; p<0,001). Quando os eventos foram estratificados por idade do óbito, naqueles que ocorreram com 20 anos ou mais, o aumento foi de 0,108 ao ano (R²=0,789; p<0,001) e, nos que ocorreram antes de 20 anos, foi de 0,023 ao ano (R²=0,188; p=0,056). A idade média ao morrer aumentou 0,617 ano por ano (R²=0,835; p<0,001). Os fatores associados ao óbito precoce identificados no modelo múltiplo foram: sexo masculino (hazard ratio — HR=1,30), raça branca (HR=1,16), morte dentro do hospital (HR=1,29) e moradia na Grande São Paulo (HR=1,13). Conclusões: Houve aumento da taxa de mortalidade e da idade média de óbito com DF nas duas últimas décadas estudadas. Os fatores sociodemográficos sexo, raça, local de ocorrência e município de residência estiveram associados com a faixa etária do óbito.

Place of death among foreign-born individuals: a national population-based register study.

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.

Concordance between COVID-19 mortality statistics derived from clinical audit and death certificates in Östergötland county, Sweden.

OBJECTIVES: Despite early notions that correct attribution of deaths caused by SARS-CoV-2 infection is critical to the understanding of the COVID-19 pandemic, three years later, the accuracy of COVID-19 death counts is still contested. We aimed to compare official death statistics with cause-of-death assessments made in a clinical audit routine by experienced physicians having access to the full medical record. STUDY DESIGN: Health service quality evaluation. METHODS: In Östergötland county (pop. 465,000), Sweden, a clinical audit team assessed from the start of the pandemic the cause of death in individuals having deceased after testing positive for SARS-CoV-2. We estimated the concordance between official data on COVID-19 deaths and data from the clinical audit using correlations (r) between the cause-of-death categories and discrepancies between the absolute numbers of categorised deaths. RESULTS: The concordance between the data sources was poor regarding whether COVID-19 was the underlying or a contributing cause of death. Grouping of the causes increased the correlations to acceptable strength. Also including deaths implicated by a positive SARS-CoV-2 test in the clinical categorisation of COVID-19 deaths reduced the difference in absolute number of deaths; with these modifications, the concordance was acceptable before the COVID-19 vaccination program was initiated (r = 0.97; symmetric mean absolute percentage error (SMAPE) = 19%), while a difference in the absolute numbers of deaths remained in the vaccination period (r = 0.94; SMAPE = 35%). CONCLUSIONS: This study highlights that carefulness is warranted when COVID-19 death statistics are used in health service planning and resonates a need for further research on cause-of-death recording methodologies.

What can death records tell us about multimorbidity?

BACKGROUND: Multimorbidity has been measured from many data sources which show that prevalence increases with age and is usually greater among women than men and in more recent periods. Analyses of multiple cause of death data have shown different patterns of multimorbidity associated with demographic and other characteristics. METHODS: Deaths in Australia among over 1.7 million decedents aged 55+ were stratified into three types: medically certified deaths, coroner-referred deaths with natural underlying causes and coroner-referred deaths with external underlying causes. Multimorbidity was measured by prevalence of ≥2 causes and analysed over three periods based on administrative changes: 2006-2012, 2013-2016 and 2017-2018. Poisson regression was used to examine the influence of gender, age and period. RESULTS: The prevalence of deaths with multimorbidity was 81.0% for medically certified deaths, 61.1% for coroner-referred deaths with natural underlying causes and 82.4% for coroner-referred deaths with external underlying causes. For medically certified deaths, multimorbidity increased with age: incidence rate ratio (IRR 1.070, 95% CI 1.068, 1.072) was lower for women than men (0.954, 95% CI 0.952, 0.956) and changed little over time. For coroner-referred deaths with natural underlying causes, multimorbidity showed the expected pattern increasing with age (1.066, 95% CI 1.062, 1.070) and being higher for women than men (1.025, 95% CI 1.015, 1.035) and in more recent periods. For coroner-referred deaths with external underlying causes, there were marked increases over time that differed by age group due to changes in coding processes. CONCLUSION: Death records can be used to examine multimorbidity in national populations but, like other data sources, how the data were collected and coded impacts the conclusions.

Mortality in children with epilepsy: Cohort study using the clinical practice research datalink.

OBJECTIVE: To estimate Mortality Rate (MR) in UK children with epilepsy (CWE) compared to children without epilepsy (CWOE), describe causes of death, determine Mortality Rate Ratios (MRRs) for cause-specific mortality, and to analyse the contribution of co-morbidities (respiratory disease, neoplasm, and congenital disorders) to mortality rate. METHOD: Retrospective cohort study of children born between 1998 and 2017, using linked data from the Clinical Practice Research Datalink Gold (Set 18). Epilepsy diagnoses were identified using previously validated codes. Causes of death were defined as natural or non-natural. Epilepsy-related deaths in CWE were those where underlying or contributing cause of death was epilepsy, status epilepticus, seizures, ill-defined/unknown cause or sudden death. We used Cox proportional hazard analysis to investigate associations of epilepsy and mortality. RESULTS: There were 1,191,304 children followed for 13,994,916 person-years (median: 12) if which 9665 (0.8%) had epilepsy. Amongst CWE, 3.4% died. MR of CWE was 4.1 (95%CI 3.7-4.6)/1,000 person-years. CWE had an increased adjusted all-cause mortality (MRR 50.9,95%CI 44.8-57.7) compared to CWOE. Amongst the 330 deaths in CWE, 323 (98%) were natural, 7 (2%) non-natural, 80 (24%) epilepsy-related. MRR of non-natural deaths was 2.09 (95%CI 0.92,4.74, p = 0.08). SIGNIFICANCE: Amongst CWE, 3.4% died during the study period. All-cause mortality rate in CWE was 4/1,000 person-years representing a fifty-fold increased mortality risk, after taking into account sex and socioeconomic status, compared to similarly aged children who did not have epilepsy. Causes of death mostly were not seizure-related. Non-natural death in CWE was uncommon.

Evaluation of errors in death certification by medical officers in an acute hospital.

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.

[Places of death of COVID-19 patients: an observational study based on evaluated death certificates from the city of Muenster, Germany (2021)]. / Sterbeorte von COVID-19-Patienten: eine Observationsstudie auf Grundlage ausgewerteter Todesbescheinigungen der Stadt Münster (2021).

INTRODUCTION: The places of death of COVID-19 patients have so far hardly been investigated in Germany. METHODS: In a places of death study in Westphalia (Germany), statistical evaluations were carried out in the city of Muenster on the basis of all death certificates from 2021. Persons who had died with or from a COVID-19 infection were identified by medical information on cause of death and analyzed with descriptive statistical methods using SPSS. RESULTS: A total of 4044 death certificates were evaluated, and 182 deceased COVID-19 patients were identified (4.5%). In 159 infected patients (3.9%), the viral infection was fatal, whereby the distribution of places of death was as follows: 88.1% in hospital (57.2% in the intensive care unit; 0.0% in the palliative care unit), 0.0% in hospice, 10.7% in nursing homes, 1.3% at home, and 0.0% in other places. All infected patients < 60 years and 75.4% of elderly patients ≥ 80 years died in hospital. Only two COVID-19 patients, both over 80 years old, died at home. COVID-19 deaths in nursing homes (17) affected mostly elderly female residents. Ten of these residents had received end-of-life care from a specialized outpatient palliative care team. DISCUSSION: The majority of COVID-19 patients died in hospital. This can be explained by the rapid course of the disease with a high symptom burden and the frequent young age of the patients. Inpatient nursing facilities played a certain role as a place of death in local outbreaks. COVID-19 patients rarely died at home. Infection control measures may be one reason why no patients died in hospices or palliative care units.

Changes in the Place of Death and Implications for End-of-Life Care Policy: A Population-Based Observational Study.

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.
