Temporal trends and sex differences in sudden cardiac death in the Copenhagen City Heart Study.

OBJECTIVE: More knowledge about the development of sudden cardiac death (SCD) in the general population is needed to develop meaningful predictors of SCD. Our aim with this study was to estimate the incidence of SCD in the general population and examine the temporal changes, demographics and clinical characteristics. METHODS: All participants in the Copenhagen City Heart Study were followed from 1993 to 2016. All death certificates, autopsy reports and national registry data were used to identify all cases of SCD. RESULTS: A total of 14 562 subjects were included in this study. There were 8394 deaths with all information available, whereof 1335 were categorised as SCD. The incidence of SCD decreased during the study period by 41% for persons aged 40-90 years, and the standardised incidence rates decreased from 504 per 100 000 person-years (95% CI 447 to 569) to 237 per 100 000 person-years (95% CI 195 to 289). The incidence rate ratio of SCD between men and women ≤75 years was 1.99 (95% CI 1.62 to 2.46). The proportion of SCD of all cardiac deaths decreased during the observation period and decreased with increasing age. Men had more cardiovascular comorbidities (OR 1.34, 95% CI 1.07 to 1.68, p<0. 01), and SCD was the first registered manifestation of cardiac disease in 50% of all cases. CONCLUSION: The incidence of SCD in the general population has declined significantly during the study period but should be further investigated for more recent variations as well as novel risk predictors for persons with low to medium risk of SCD.

Perceived Impediments to Completed Brain Autopsies Among Diverse Older Adults Who Have Signed a Uniform Anatomical Gift Act for Brain Donation for Clinical Research.

Background: A small number of older adults in the United States who agree to brain donation for clinical research belong to diverse racial, ethnic, and economic groups. Those who agree, however, are less likely to have completed brain autopsies compared with older non-Latino Whites of higher socioeconomic status. As such, our understanding of Alzheimer's disease and related dementias remains limited in these underrepresented and understudied populations. Here, we examine perceived impediments to completed brain autopsies among diverse older adults who have agreed to brain donation for clinical research. Methods: Participants (N=22) were older adults (mean age=77 years) who self-identified as African American (n=8), Latino (n=6), or White of lower income (n=8). All participants had previously agreed to brain donation via the Uniform Anatomical Gift Act. Each participant took part in a one-time, semi-structured focus group. Data were analyzed using a Grounded Theory Approach with both Open Coding and Constant Comparative Coding. Results: Perceived impediments to completed brain autopsies varied by group. Older African Americans and older Latinos expressed concern about a lack of follow-through by family members regarding their brain donation wishes. Older Whites of lower income indicated that their own uncertainty surrounding the processes of brain donation and brain autopsy might serve as an impediment. Discussion: Diverse older adults expressed different perceived impediments to having brain autopsies completed upon their death. Continuous education for diverse older adults and their family members regarding brain donation for clinical research, including clear guidelines and processes, may facilitate completed brain autopsies among diverse older adults.

Emerging Lingo-Cultural Inequality in Infant Autopsy in Quebec, Canada.

We investigated trends in infant autopsy for Francophones and Anglophones in Quebec, Canada. Using death certificates, we extracted 8214 infant deaths between 1989 and 2013. We computed rates of non-autopsy by language, socioeconomic disadvantage, age at death, and period. Using Kitagawa's method, we decomposed non-autopsy rates over time for both language groups. Infant non-autopsy rates increased from 38.6 to 56.2 per 100 for Francophones, and from 41.2 to 57.2 per 100 for Anglophones, between 1989-1995 and 2008-2013. Trends in English-speakers were driven by socioeconomically disadvantaged Anglophones, and were accelerated by a larger proportion of deaths in this group over time. For French-speakers, rates increased in all socioeconomic groups. The increase in non-autopsy rates was larger at early neonatal ages for both languages. These findings suggest that disadvantaged Anglophones are less likely to use infant autopsy over time, and that rates can be improved by targeting early neonatal deaths.

[The coroner's autopsies in the Great Britain: the problems related to the quality of the studies, standardization, auditing, financial support and the approaches to their solution]. / Koronerskaia autopsiia v Velikobritanii: problemy kachestva issledovanii, standartizatsii, audita, finansirovaniia i puti ikh resheniia.

This article continues the series of previous publications of the authors based on the analysis of the detailed report of the experts of the National Confidential Enquiry into Patient Outcome and Death program (NCEPOD) designed to evaluate the quality of autopsies carried out by the coroners in the Great Britain. It was shown that only in 13 to 55% of the 1,691 case the operators had an opportunity to refer the necropsy materials for the pathological study. The problems encountered in association with histological and toxicological analysis arose from the misunderstanding between the coroners and the pathologists as regard the organizational aspects of autopsy studies as swell as the financial and economic considerations. The Coroner Rules that had been adopted in 1984 and remained in force in the country until 2005 needed to be radically revised, corrected, and amended to facilitate the solution of a number of problems and eliminate the formal organizational and technical contradictions that hampered the further improvement of the quality of autopsies that must be performed by the corners at the national rather than the local level. The maximum number of the unacceptable results were revealed in the protocols of autopsires carried out by the forensic medical experts. All pathologists in the Great Britain are recommended to pay special attention to all cases of sudden death of the adult subjects and the deceased epileptic patients. The detailed investigations are mandatory in all cases of death following medical manipulations, such as surgical interventions, and complications.

Health professionals' and coroners' views on less invasive perinatal and paediatric autopsy: a qualitative study.

OBJECTIVE: To assess health professionals' and coroners' attitudes towards non-minimally and minimally invasive autopsy in the perinatal and paediatric setting. METHODS: A qualitative study using semistructured interviews. Data were analysed thematically. RESULTS: Twenty-five health professionals (including perinatal/paediatric pathologists and anatomical pathology technologists, obstetricians, fetal medicine consultants and bereavement midwives, intensive care consultants and family liaison nurses, a consultant neonatologist and a paediatric radiologist) and four coroners participated. Participants viewed less invasive methods of autopsy as a positive development in prenatal and paediatric care that could increase autopsy rates. Several procedural and psychological benefits were highlighted including improved diagnostic accuracy in some circumstances, potential for faster turnaround times, parental familiarity with imaging and laparoscopic approaches, and benefits to parents and faith groups who object to invasive approaches. Concerns around the limitations of the technology such not reaching the same levels of certainty as full autopsy, unsuitability of imaging in certain circumstances, the potential for missing a diagnosis (or misdiagnosis) and de-skilling the workforce were identified. Finally, a number of implementation issues were raised including skills and training requirements for pathologists and radiologists, access to scanning equipment, required computational infrastructure, need for a multidisciplinary approach to interpret results, cost implications, equity of access and acceptance from health professionals and hospital managers. CONCLUSION: Health professionals and coroners viewed less invasive autopsy as a positive development in perinatal and paediatric care. However, to inform implementation a detailed health economic analysis and further exploration of parental views, particularly in different religious groups, are required.

The Regional Autopsy Center: The University of Alabama at Birmingham Experience.

Rates of autopsied deaths have decreased significantly for the last several decades. It may not be practical for some institutions to maintain the facilities and staffing required to perform autopsies. In recent years, the University of Alabama at Birmingham (UAB) has established contracts to perform autopsies for several regional institutions including the Alabama Department of Forensic Sciences (ADFS), the United States Veterans Affairs, the local prison system, local community hospitals, and with families for private autopsy services. Contracts and autopsy data from 2004 to 2015 were obtained and reviewed. Since 2004, the number of UAB hospital autopsies trended slightly downward. On average, UAB hospital cases comprised most yearly cases, and the ADFS was the second largest contributor of cases. Income generated from outside autopsies performed from 2006 to 2015 totaled just more than 2 million dollars, and most of the income was generated from referred ADFS cases. This study provides evidence that a centralized institution (regional autopsy center [RAC]) can provide regional autopsy service in a practical, feasible, and economically viable manner, and a RAC can benefit both the referring institutions as well as the RAC itself.

Inequality in Fetal Autopsy in Canada.

PURPOSE: Inequality in use of fetal autopsy is poorly understood, despite the importance of autopsy in establishing the cause of stillbirth for future prevention. We examined fetal autopsy rates between linguistic minorities in Quebec, Canada, and assessed trends over three decades. METHODS: Using registry data on 11,992 stillbirths from 1981-2011, we calculated fetal autopsy rates for Francophones, Anglophones, and Allophones by decade. RESULTS: We found lower fetal autopsy rates for Allophones (54.4%) than Francophones (68.5%) and Anglophones (63.4%), but rates decreased over time for all language groups. After 2000, Allophones had 25% higher risk of non-autopsy relative to Francophones, with 8.8 fewer autopsies for every 100 stillbirths. Allophones who were not autopsied had 32% higher risk of having an undetermined cause of death. CONCLUSION: Inequality in use of fetal autopsy may be widespread for minorities in Canada. Efforts to decrease stillbirth in minorities may require policies to increase autopsy rates.

A Case Controlled Examination of the Interpersonal Theory of Suicide in the Second Half of Life.

The interpersonal theory of suicide proposes that the most proximal cause of suicide is the combination of thwarted belongingness and perceived burdensomeness coupled with a pre-existing vulnerability of reduced fear of death and increased pain tolerance. This pre-existing vulnerability develops in response to painful and provocative life events. According to the theory, empirically demonstrated risk factors for suicide operate by increasing the likelihood of one or more of the theory's constructs. The current study examined the relations of the major constructs of the interpersonal theory with suicide case status compared to living controls in the second half of life. The current study used a pre-existing psychological autopsy database to compare suicide decedents to living controls 50 years and older. Theory constructs were measured by composite scores of thwarted belongingness, perceived burdensomeness, and painful and provocative experiences using an a priori selection of items comprising each construct. Suicide decedents experienced greater levels of all three of the theory's constructs when examined independently compared to living controls. When examined simultaneously while also controlling for Major Depression, greater perceived burdensomeness and painful and provocative experiences were associated with suicide case status (vs. control). The interpersonal theory is a comprehensive framework that may be useful in understanding risk for death by suicide in the second half of life. Clinical management of suicide risk for adults in the second half of life could include a focus on perceived burdensomeness, as the IPTS proposes that this psychological state is amenable to change via therapeutic intervention.

Neuropathologic assessment of participants in two multi-center longitudinal observational studies: the Alzheimer Disease Neuroimaging Initiative (ADNI) and the Dominantly Inherited Alzheimer Network (DIAN).

It has been hypothesized that the relatively rare autosomal dominant Alzheimer disease (ADAD) may be a useful model of the more frequent, sporadic, late-onset AD (LOAD). Individuals with ADAD have a predictable age at onset and the biomarker profile of ADAD participants in the preclinical stage may be used to predict disease progression and clinical onset. However, the extent to which the pathogenesis and neuropathology of ADAD overlaps with that of LOAD is equivocal. To address this uncertainty, two multicenter longitudinal observational studies, the Alzheimer Disease Neuroimaging Initiative (ADNI) and the Dominantly Inherited Alzheimer Network (DIAN), leveraged the expertise and resources of the existing Knight Alzheimer Disease Research Center (ADRC) at Washington University School of Medicine, St. Louis, Missouri, USA, to establish a Neuropathology Core (NPC). The ADNI/DIAN-NPC is systematically examining the brains of all participants who come to autopsy at the 59 ADNI sites in the USA and Canada and the 14 DIAN sites in the USA (eight), Australia (three), UK (one) and Germany (two). By 2014, 41 ADNI and 24 DIAN autopsies (involving nine participants and 15 family members) had been performed. The autopsy rate in the ADNI cohort in the most recent year was 93% (total since NPC inception: 70%). In summary, the ADNI/DIAN NPC has implemented a standard protocol for all sites to solicit permission for brain autopsy and to send brain tissue to the NPC for a standardized, uniform and state-of-the-art neuropathologic assessment. The benefit to ADNI and DIAN of the implementation of the NPC is very clear. The NPC provides final "gold standard" neuropathological diagnoses and data against which the antecedent observations and measurements of ADNI and DIAN can be compared.

Cost-consequence analysis of cause of death investigation in Finland and in Denmark.

The 1990s 12-16% total autopsy rate in Denmark has until now declined to 4%, while in Finland, it has remained between 25 and 30%. The decision to proceed with a forensic autopsy is based on national legislation, but it can be assumed that the financing of autopsies influences the decision process. Only little is known about the possible differences between health economics of Finnish and Danish cause of death investigation systems. The aims of this article were to analyse costs and consequences of Finnish and Danish cause of death investigations, and to develop an alternative autopsy practice in Denmark with another cost profile. Data on cause of death investigation systems and costs were derived from Departments of Forensic Medicine, Departments of Pathology, and the National Police. Finnish and Danish autopsy rates were calculated in unnatural (accident, suicide, homicide and undetermined intent) and natural (disease) deaths, and used to develop an alternative autopsy practice in Denmark. Consequences for society were analysed. The estimated unit cost (€) for one forensic autopsy is 3.2 times lower in Finland than in Denmark (€1400 versus €4420), but in Finland the salaries for forensic pathologists working at the National Institute for Health and Welfare are not included in the unit cost. The unit cost for one medical autopsy is also lower in Finland than in Denmark; €700 versus €1070. In our alternative practice in Denmark, the forensic autopsy rate was increased from 2.2% to 8.5%, and the medical autopsy rate from 2.4% to 5.8%. Costs per 10,000 deaths were estimated to be 50% (±25%) higher than now; i.e. €3,678,724 (2,759,112-4,598,336), but would result in a lower unit cost for forensic autopsies €3,094 (2,320-3,868) and for medical autopsies €749 (562-936). This practice would produce a higher accuracy of national mortality statistics, which, consequently, would entail higher quality in public health, an accurate basis for decision-making in health politics, and better legislative safety in society. The implementation of this alternative practice in Denmark requires that legislation demands that forensic autopsy be performed if causality between unnatural death and cause of death cannot be clarified or if cause of death remains unknown. The Danish Health and Medicines Authority should provide guidelines that request a medical autopsy in natural deaths where more information about disease as a cause of death is needed. Our study results warrant similar health economic analyses of different cause of death investigations in other countries.

Through the lens of the clinician: autopsy services and utilization in a large teaching hospital in Ghana.

BACKGROUND: Declining hospital autopsy rates in many countries have generated considerable concern. The survey determined challenges of the autopsy service in a large Teaching Hospital in Ghana, from the perspective of clinicians. METHODS: This was a cross-sectional study of doctors at the Korle-Bu Teaching Hospital (KBTH) over in 2012. The data was collected using a 69 item self-administered structured questionnaire. In all a total of 215 questionnaires were sent out and 119 doctors responded. Data was collected on the challenges of the autopsy services and barriers to autopsy request from the perspectives of clinicians. Survey data were analyzed by simple descriptive statistics (i.e. proportions, ratios and percentages. Data from survey was analyzed with SPSS version 21. RESULTS: The most common reasons for requesting autopsies were to answer clinical questions, 55 (46.2%) and in cases of uncertain diagnosis, 54 (45.4%). Main demand side barriers to the use of autopsy services by clinicians were reluctance of family to give consent for autopsy 100 (84%), due to cultural and religious objections 89 (74.8%), extra funeral cost to family53 (44.5%) and increased duration of stay of body in the morgue 19 (16%). Health system barriers included delayed feedback from autopsy service 54 (45.4%), difficulties following up the autopsy process 40 (33.6%) due to uncertainties in the timing of particular events in the autopsy process, and long waiting time for autopsy reports 81 (68.1%). More than a third of clinicians 43 (36.2%), received full autopsy report beyond three weeks and 75 (63.1%) clinicians had concerns with the validity of reports issued by the autopsy service (i.e. reports lack specificity or at variance with clinical diagnosis, no toxicological, histological or tissue diagnoses are performed). CONCLUSION: The autopsy service should restructure itself efficiently and management should support the provision of histological and toxicological services. Strengthening internal and external quality improvement and control of autopsies in the Hospital are essential.

[Unnatural deaths must be investigated better--risk of crimes being missed. Examination of the police and the health care system management of deaths in three counties]. / Onaturliga dödsfall måste utredas bättre - risk att brott missas - Granskning av polisens och sjukvårdens dödsfallshandläggning i tre län.

In 2008 only 55 % of all deaths not deemed to be natural in Sweden underwent a medicolegal autopsy. In the present study we describe and compare the characteristics of unnatural deaths in three counties through review of death certificates for unnatural deaths and, when applicable, corresponding police reports. The majority of unnatural deaths that were not reported to the police were among elderly decedents, with the deaths most often resulting from a fall-related fracture or head injury. One subgroup among these deaths that were not recognized as reportable by the involved physician, estimated by extrapolation to a total of approximately 300 annually, nationwide, was considered to be at elevated risk for a criminal death (homicide). The causes of death in this group were due to, for example, high energy or sharp force trauma, gunshot injury, asphyxia, and drug and/or alcohol intoxication. We conclude that additional training in the handling of unnatural deaths is indicated for Swedish physicians.

[Autopsy-a procedure of medical history?]. / Die Obduktion - ein Verfahren der Medizingeschichte?

An autopsy is an important tool of quality assurance in clinical medicine. It serves to determine the exact cause of death, unravel unexpected complications of disease processes including adverse or any other effects of treatment as well as to validate the official mortality statistics. An autopsy also makes an important contribution to training medical students and physicians; however, the rate of clinical autopsies has been declining drastically for decades, the causes being manifold. Lack of interest among clinicians, mainly due to inadequate knowledge of the advantages of autopsy seems to play a special role. The lack of reasonable reimbursement has also been discussed as another possible cause. In order to counteract this negative trend, efforts should be made to work on the awareness of medical students and young clinicians so that an autopsy is perceived as a general measure of quality assurance and physician self-control. Furthermore, a realistic reimbursement of financial and personnel expense is necessary.

Routine perinatal and paediatric post-mortem radiography: detection rates and implications for practice.

BACKGROUND: Routine perinatal and paediatric post-mortem plain radiography allows for the diagnosis and assessment of skeletal dysplasias, fractures and other bony abnormalities. OBJECTIVE: The aim of this study was to review the diagnostic yield of this practice. MATERIALS AND METHODS: We identified 1,027 cases performed in a single institution over a 2½-year period, including babygrams (whole-body examinations) and full skeletal surveys. Images were reported prior to autopsy in all cases. Radiology findings were cross-referenced with the autopsy findings using an autopsy database. We scored each case from 0 to 4 according to the level of diagnostic usefulness. RESULTS: The overall abnormality rate was 126/1,027 (12.3%). There was a significantly higher rate of abnormality when a skeletal survey was performed (18%) rather than a babygram (10%; P < 0.01); 90% (665/739) of babygrams were normal. Of the 74 abnormal babygrams, we found 33 incidental non-contributory cases, 19 contributory, 20 diagnostic, and 2 false-positive cases. There were only 2 cases out of 739 (0.27%) in whom routine post-mortem imaging identified potentially significant abnormalities that would not have been detected if only selected imaging had been performed. A policy of performing selected, rather than routine, foetal post-mortem radiography could result in a significant cost saving. CONCLUSION: Routine post-mortem paediatric radiography in foetuses and neonates is neither diagnostically useful nor cost-effective. A more evidence-based, selective protocol should yield significant cost savings.

Characteristics of medical examiner/coroner offices accredited by the National Association of Medical Examiners.

The National Association of Medical Examiners accredits medical examiner and coroner offices. Approximately 60 offices were fully or provisionally accredited as of late 2011, and these offices serve one-quarter of the U.S. population. The calculated average population served was 1.6M but ranged from 0.3 to 10.5M. The calculated mean death rate was 794 deaths/100K population, and the mean homicide rate was 7.2 homicides/100K population. The calculated mean budget was $4.35M, but budgets ranged from $0.67 to $26.8M. The calculated mean budget/capita was $3.02 but ranged from $0.62 to $10.22. The average size of the facility was under 30,000 sq. ft. The calculated average staffing was found to include five forensic pathologists, four and a half autopsy technicians, and nine investigators. The mean forensic pathologists/1M population was 3.7. Calculated workload indices included 222 autopsies/pathologist and an autopsy rate of 77.6/100K population. These results show that offices of every size can achieve accreditation.
