Reclaiming the Autopsy as the Practice of Medicine: A Pathway to Remediation of the Forensic Pathology Workforce Shortage?

The historically constricted forensic pathology workforce pipeline is facing an existential crisis. Pathology residents are exposed to forensic pathology through the American Council of Graduate Medical Education autopsy requirement. In 1950, autopsies were conducted in one half of the patients dying in American hospitals and 90% in teaching hospitals, but they have dwindled to fewer than 5%. Elimination of funding for autopsies is a major contributor to the lack of support for autopsies in departments of pathology. Funding may require reclaiming the autopsy as the practice of medicine. Funding of autopsies would rekindle interest in hospital autopsies and strengthen the forensic pathology workforce pipeline.

Fast and efficient analyses of the post-mortem human blood and bone marrow using DI-SPME/LC-TOFMS method for forensic medicine purposes.

For the first time the method DI-SPME/LC-TOFMS was used and developed in order to determine the large antidepressant drugs in real forensic cases. The aim of the study was to optimize the new DI-SPME/LC-TOFMS method for the quantification of the large group of psychotropic drugs such as benzodiazepines, selective serotonin reuptake inhibitors, selective serotonin and noradrenaline reuptake inhibitors, tricyclic antidepressants and sleeping pills "Z". The volume of the sample, adsorption time, post-adsorption purification and desorption time were precisely optimized. The validation parameters such as limit of detection and quantification, linearity, precision during and between days and the matrix effect were determined. All obtained values are within the acceptable range for toxicological analyses. The usefulness of the method was confirmed by analyzing the post-mortem samples. Drug concentrations were determined in real samples with high precision, which gives perspectives for the DI-SPME/LC-TOFMS routine application in toxicological and forensic analyses in the future.

Identifying Child Abuse Fatalities During Infancy.

When a healthy infant dies suddenly and unexpectedly, it is critical to correctly determine if the death was caused by child abuse or neglect. Sudden unexpected infant deaths should be comprehensively investigated, ancillary tests and forensic procedures should be used to more-accurately identify the cause of death, and parents deserve to be approached in a nonaccusatory manner during the investigation. Missing a child abuse death can place other children at risk, and inappropriately approaching a sleep-related death as maltreatment can result in inappropriate criminal and protective services investigations. Communities can learn from these deaths by using multidisciplinary child death reviews. Pediatricians can support families during investigation, advocate for and support state policies that require autopsies and scene investigation, and advocate for establishing comprehensive and fully funded child death investigation and reviews at the local and state levels. Additional funding is also needed for research to advance our ability to prevent these deaths.

Hospital implementation of minimally invasive autopsy: A prospective cohort study of clinical performance and costs.

OBJECTIVES: Autopsy rates worldwide have dropped significantly over the last decades and imaging-based autopsies are increasingly used as an alternative to conventional autopsy. Our aim was to evaluate the clinical performance and cost of minimally invasive autopsy. METHODS: This study was part of a prospective cohort study evaluating a newly implemented minimally invasive autopsy consisting of MRI, CT, and biopsies. We calculated diagnostic yield and clinical utility-defined as the percentage successfully answered clinical questions-of minimally invasive autopsy. We performed minimally invasive autopsy in 46 deceased (30 men, 16 women; mean age 62.9±17.5, min-max: 18-91). RESULTS: Ninety-six major diagnoses were found with the minimally invasive autopsy of which 47/96 (49.0%) were new diagnoses. CT found 65/96 (67.7%) major diagnoses and MRI found 82/96 (85.4%) major diagnoses. Eighty-four clinical questions were asked in all cases. Seventy-one (84.5%) of these questions could be answered with minimally invasive autopsy. CT successfully answered 34/84 (40.5%) clinical questions; in 23/84 (27.4%) without the need for biopsies, and in 11/84 (13.0%) a biopsy was required. MRI successfully answered 60/84 (71.4%) clinical questions, in 27/84 (32.1%) without the need for biopsies, and in 33/84 (39.8%) a biopsy was required. The mean cost of a minimally invasive autopsy was €1296 including brain biopsies and €1087 without brain biopsies. Mean cost of CT was €187 and of MRI €284. CONCLUSIONS: A minimally invasive autopsy, consisting of CT, MRI and CT-guided biopsies, performs well in answering clinical questions and detecting major diagnoses. However, the diagnostic yield and clinical utility were quite low for postmortem CT and MRI as standalone modalities.

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.

Collecting verbal autopsies: improving and streamlining data collection processes using electronic tablets.

BACKGROUND: There is increasing interest in using verbal autopsy to produce nationally representative population-level estimates of causes of death. However, the burden of processing a large quantity of surveys collected with paper and pencil has been a barrier to scaling up verbal autopsy surveillance. Direct electronic data capture has been used in other large-scale surveys and can be used in verbal autopsy as well, to reduce time and cost of going from collected data to actionable information. METHODS: We collected verbal autopsy interviews using paper and pencil and using electronic tablets at two sites, and measured the cost and time required to process the surveys for analysis. From these cost and time data, we extrapolated costs associated with conducting large-scale surveillance with verbal autopsy. RESULTS: We found that the median time between data collection and data entry for surveys collected on paper and pencil was approximately 3 months. For surveys collected on electronic tablets, this was less than 2 days. For small-scale surveys, we found that the upfront costs of purchasing electronic tablets was the primary cost and resulted in a higher total cost. For large-scale surveys, the costs associated with data entry exceeded the cost of the tablets, so electronic data capture provides both a quicker and cheaper method of data collection. CONCLUSIONS: As countries increase verbal autopsy surveillance, it is important to consider the best way to design sustainable systems for data collection. Electronic data capture has the potential to greatly reduce the time and costs associated with data collection. For long-term, large-scale surveillance required by national vital statistical systems, electronic data capture reduces costs and allows data to be available sooner.

Application of the condensed protocol for the NIA-AA guidelines for the neuropathological assessment of Alzheimer's disease in an academic clinical practice.

AIMS: In response to concerns regarding resource expenditures required to implement fully the 2012 National Institute on Aging and the Alzheimer's Association (NIA-AA) Sponsored Guidelines for the neuropathological assessment of Alzheimer's disease (AD), we previously developed a sensitive and cost-reducing condensed protocol (CP) at the University of Washington (UW) Alzheimer's Disease Research Center (ADRC) that consolidated the recommended NIA-AA protocol into fewer cassettes requiring fewer immunohistochemical stains. The CP was not designed to replace NIA-AA protocols, but instead to make the NIA-AA criteria accessible to clinical and forensic neuropathology practices where resources limit full implementation of NIA-AA guidelines. METHODS AND RESULTS: In this regard, we developed practical criteria to instigate CP sampling and immunostaining, and applied these criteria in an academic clinical neuropathological practice. During the course of 1 year, 73 cases were sampled using the CP; of those, 53 (72.6%) contained histological features that prompted CP work-up. We found that the CP resulted in increased identification of AD and Lewy body disease neuropathological changes from what was expected using a clinical history-driven work-up alone, while saving approximately $900 per case. CONCLUSIONS: This study demonstrates the feasibility and cost-savings of the CP applied to a clinical autopsy practice, and highlights potentially unrecognised neurodegenerative disease processes in the general ageing community.

Sustainable Development of Pathology in Sub-Saharan Africa: An Example From Ghana.

CONTEXT: - Pathology services are poorly developed in Sub-Saharan Africa. Komfo Anokye Teaching Hospital in Kumasi, Ghana, asked for help from the pathology department of the University Hospital of North Norway, Tromsø. OBJECTIVE: - To reestablish surgical pathology and cytology in an African pathology department in which these functions had ceased completely, and to develop the department into a self-supporting unit of good international standard and with the capacity to train new pathologists. DESIGN: - Medical technologists from Kumasi were trained in histotechnology in Norway, they were returned to Kumasi, and they produced histologic slides that were temporarily sent to Norway for diagnosis. Two Ghanaian doctors received pathology training for 4 years in Norway. Mutual visits by pathologists and technologists from the 2 hospitals were arranged for the introduction of immunohistochemistry and cytology. Pathologists from Norway visited Kumasi for 1 month each year during 2007-2010. Microscopes and immunohistochemistry equipment were provided from Norway. Other laboratory equipment and a new building were provided by the Ghanaian hospital. RESULTS: - The Ghanaian hospital had a surgical pathology service from the first project year. At 11 years after the start of the project, the services included autopsy, surgical pathology, cytopathology, frozen sections, and limited use of immunohistochemistry, and the department had 10 residents at different levels of training. CONCLUSIONS: - A Ghanaian pathology department that performed autopsies only was developed into a self-supported department with surgical pathology, cytology, immunohistochemistry, and frozen section service, with an active residency program and the capacity for further development that is independent from assistance abroad.

The Decline of the Autopsy in Rhode Island and Nationwide: Past Trends and Future Directions.

The autopsy has long been a fundamental aspect of medical practice and research. However, in the last 50 years, the proportion of deaths for which an autopsy is performed has decreased dramatically. Here we examine some of the reasons for the decline of the autopsy, as well as several interventions that have been proposed to revive it. We also present autopsy utilization data from the Lifespan system, which mirrors nationwide trends. [Full article available at http://rimed.org/rimedicaljournal-2016-10.asp].

Pathological Methods Applied to the Investigation of Causes of Death in Developing Countries: Minimally Invasive Autopsy Approach.

BACKGROUND AND AIMS: Complete diagnostic autopsies (CDA) remain the gold standard in the determination of cause of death (CoD). However, performing CDAs in developing countries is challenging due to limited facilities and human resources, and poor acceptability. We aimed to develop and test a simplified minimally invasive autopsy (MIA) procedure involving organ-directed sampling with microbiology and pathology analyses implementable by trained technicians in low- income settings. METHODS: A standardized scheme for the MIA has been developed and tested in a series of 30 autopsies performed at the Maputo Central Hospital, Mozambique. The procedure involves the collection of 20 mL of blood and cerebrospinal fluid (CSF) and puncture of liver, lungs, heart, spleen, kidneys, bone marrow and brain in all cases plus uterus in women of childbearing age, using biopsy needles. RESULTS: The sampling success ranged from 67% for the kidney to 100% for blood, CSF, lung, liver and brain. The amount of tissue obtained in the procedure varied from less than 10 mm2 for the lung, spleen and kidney, to over 35 mm2 for the liver and brain. A CoD was identified in the histological and/or the microbiological analysis in 83% of the MIAs. CONCLUSIONS: A simplified MIA technique allows obtaining adequate material from body fluids and major organs leading to accurate diagnoses. This procedure could improve the determination of CoD in developing countries.

How much does a verbal autopsy based mortality surveillance system cost in rural India?

OBJECTIVE: This paper aims to determine the cost of establishing and sustaining a verbal-autopsy based mortality surveillance system in rural India. MATERIALS AND METHODS: Deaths occurring in 45 villages (population 185,629) were documented over a 4-year period from 2003-2007 by 45 non-physician healthcare workers (NPHWs) trained in data collection using a verbal autopsy tool. Causes of death were assigned by 2 physicians for the first year and by one physician for the subsequent years. Costs were calculated for training of interviewers and physicians, data collection, verbal autopsy analysis, project management and infrastructure. Costs were divided by the number of deaths and the population covered in the year. RESULTS: Verbal-autopsies were completed for 96.7% (5786) of all deaths (5895) recorded. The annual cost in year 1 was INR 1,133,491 (USD 24,943) and the total cost per death was INR 757 (USD 16.66). These costs included training of NPHWs and physician reviewers Rs 67,025 (USD 1474), data collection INR 248,400 (USD 5466), dual physician review for cause of death assignment INR 375,000 (USD 8252), and project management INR 341,724 (USD 7520). The average annual cost to run the system each year was INR 822,717 (USD18104) and the cost per death was INR 549 (USD 12) for the next 3 years. Costs were reduced by using single physician review and shortened re-training sessions. The annual cost of running a surveillance system was INR 900,410 (USD 19814). DISCUSSION: This study provides detailed empirical evidence of the costs involved in running a mortality surveillance site using verbal-autopsy.

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.

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.
