Ensuring Safety of Forensic Medical Examiners during Autopsy of Suspected or Detected Cases of Deadly Communicable Diseases

Background: Forensic medical examiners are known to be exposed to a combined effect of occupational risk factors potentially leading to adverse health outcomes. In the current epidemiologic situation largely influenced by the ongoing COVID-19 pandemic, postmortem examination of the bodies having signs of deadly communicable diseases, including the novel coro-navirus disease, poses a high infection risk, thus making the development and implementation of appropriate preventive measures an urgent and important task. Objective: To summarize and systematize the results of scientific research and requirements of legal and regulatory documents in the field of ensuring workplace safety of forensic medical examiners. Materials and methods: We searched for literary sources published in Russian and English in 2000–2021 in the PubMed, eLibrary, and Cyberleninka databases using such keywords as "healthcare workers”, "safety”, "forensic medical examiner”, "prosector”, and "deadly infections”. We conducted an analytical review of legal documents regulating safety in the conduct of forensic medical examination. Based on the relevance of search results, we selected 30 articles and five legal and regulatory documents for this review and carried out their content analysis using descriptive and analytical methods. Results: As a solution to the problem of epidemiological surveillance, a series of modular buildings for postmortem examination of patients with suspected or confirmed deadly infectious diseases, including COVID-19, was developed and introduced. Conclusions: Our findings indicate that in the context of the current pandemic, it is critical to update the requirements for biological safety of forensic experts stipulated in sanitary rules and norms. Construction of modular special purpose buildings in the city of Kazan contributed to improvement of biological safety during autopsy of COVID-19 victims. © 2022, Federal Center for Hygiene and Epidemiology.

Roles of radiological technologists at Tsukuba Medical Examiner's Office equipped with a computed tomography system dedicated for the examination of corpses

The present study report introduces the roles of radiological technologists (RTs) at Tsukuba Medical Examiner's Office in Japan where a computed tomography system dedicated for examining corpses has been equipped. Several projects and enacted laws regarding postmortem imaging (PMI) have accelerated its use in many Japanese hospitals for detecting causes of death. The lack of sufficient forensic radiologists has led increasing need of RTs to assist forensic pathologists in a timely manner. Optimizing parameters and image processing of postmortem computed tomography (PMCT) and assistance in interpretation of PMCT using checklists by RTs help forensic pathologist to diagnose death causes and select needs for the following autopsy.

Ergonomic exposures and control measures associated with mass fatality decedent handling in morgues and body collection points in a New York healthcare system during COVID-19: A case series.

INTRODUCTION: In April 2020, novel coronavirus SARS-CoV-2 (COVID-19) produced an ongoing mass fatality event in New York. This overwhelmed hospital morgues necessitating emergent expansion of capacity in the form of refrigerated trucks, trailers, and shipping containers referred to as body collection points (BCPs). The risks for musculoskeletal injury during routine and mass fatality mortuary operations and experiences of decedent handlers throughout the "first wave" of COVID-19 are presented along with mitigation strategies. METHODS: Awareness of the high rates of musculoskeletal injury among health care workers due to ergonomic exposures from patient handling, including heavy and repetitive manual lifting, prompted safety walkthroughs of mortuary operations at multiple hospitals within a health system in New York State by workforce safety specialists. Site visits sought to identify ergonomic exposures and ameliorate risk for injury associated with decedent handling by implementing engineering, work practice, and administrative controls. RESULTS: Musculoskeletal exposures included manual lifting of decedents to high and low surfaces, non-neutral postures, maneuvering of heavy equipment, and push/pull forces associated with the transport of decedents. DISCUSSION: Risk mitigation strategies through participatory ergonomics, education on body mechanics, development of novel handling techniques implementing friction-reducing aides, procurement of specialized equipment, optimizing BCP design, and facilitation of communication between hospital and system-wide departments are presented along with lessons learned. After-action review of health system workers' compensation data found over four thousand lost workdays due to decedent handling related incidents, which illuminates the magnitude of musculoskeletal injury risk to decedent handlers.

Severe Acute Respiratory Syndrome Coronavirus 2 Surveillance in Decedents in a Large, Urban Medical Examiner's Office.

BACKGROUND: Given the challenges in implementing widespread testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), there is increasing interest in alternative surveillance strategies. METHODS: We tested nasopharyngeal swabs from 1094 decedents in the Wayne County Medical Examiner's Office for SARS-CoV-2. All decedents were assessed using a coronavirus disease 2019 (COVID-19) checklist, and decedents flagged using the checklist (298) were preferentially tested. A random sample of decedents not flagged using the checklist were also tested (796). We statistically analyzed the characteristics of decedents (age, sex, race, and manner of death), differentiating between those flagged using the checklist and not and between those SARS-CoV-2-positive and not. RESULTS: A larger percentage of decedents overall were male (70% vs 48%) and black (55% vs 36%) compared with the catchment population. Seven-day average percent positivity among flagged decedents closely matched the trajectory of percent positivity in the catchment population, particularly during the peak of the outbreak (March and April 2020). After a lull in May to mid-June, new positive tests in late June coincided with increased case detection in the catchment. We found large racial disparities in test results; SARS-CoV-2-positive decedents were substantially more likely to be black than SARS-CoV-2-negative decedents (82% vs 51%). SARS-CoV-2-positive decedents were also more likely to be older and to have died of natural causes, including of COVID-19 disease. CONCLUSIONS: Disease surveillance through medical examiners and coroners could supplement other forms of surveillance and serve as a possible early outbreak warning sign.

The roles of medical examiners in the COVID-19 era: a comparison between the United States and Italy.

Italy and the United States are two of the countries most affected by SARS-CoV-2 (COVID-19), with more than 240,760 confirmed cases in Italy and 2,699,658 in the United States (as of July 2, 2020). The current COVID-19 pandemic has led to substantial changes in many fields of medicine, specifically in the forensic discipline. Medicolegal activities related to conducting autopsies have been largely affected by the COVID-19 pandemic. Postmortem examinations are generally discouraged by government regulations due to the risk of spreading the disease further through the handling and dissection of bodies from patients who succumbed to COVID-19 infection. There is a paucity of data regarding the persistence of SARS-CoV-2 in bodies, as well as concerning the reliability of swabbing methods in human remains. On the other hand, the autopsy is an essential tool to provide necessary information about the pathophysiology of the disease that presents useful clinical and epidemiological insights. On this basis, we aim to address issues concerning general medical examiner/coroner organization, comparing the Italian and American systems. We also discuss the pivotal roles of forensic pathologists in informing infectious disease surveillance. Finally, we focus on the impact of COVID-19 emergency on medicolegal practices in Italy and the United States, as well as the responses of the forensic scientific community to the emerging concerns related to the pandemic. We believe that stronger efforts by authorities are necessary to facilitate completing postmortem examinations, as data derived from such assessments are expected to be paramount to improving patient management and disease prevention.
