Post-mortem examination in the United Kingdom: present and future

The "autopsy" enigma: etymology, related terms and unambiguous alternatives

The concerted use of Greek-derived medical terms in the present day allows us to facilitate effective communication while honouring the historic roots of Western medicine. The word autopsy derives from its third century B.C. Hellenistic Greek etymon αὐτοψία ("to see for oneself"), later borrowed into Neo-Latin as autopsia and Middle French as autopsie. Throughout its etymological journey, autopsie underwent semantic narrowing from the passive sense "self-inspection of something without touching", to a purposeful action by an operator performing "an examination of the human body itself", to specifically "dissection of a dead human body". These curious turning points for the meaning of autopsie produced an auto-antonym: the same word now has multiple meanings, of which one is the reverse of another. The French autopsie used in the latter sense predates that documented for the English autopsy (attested 1829). Since the early nineteenth century, attempts were made to remedy the discrepancy between conflicting senses either by adding determining adjectives to the existing noun, or by substituting it with another word altogether. This review explores the etymological journey of autopsy, considers which related terms have been popularised throughout history, introduces the concept of lexical ambiguity and suggests unambiguous English compound (necropsy and necrotomy) and Latin-derived (non-invasive and invasive postmortem examination) alternatives to satisfy a recent appetite for clarity in international professional and next-of-kin communication.

How much does a forensic autopsy cost in Spain?

INTRODUCTION AND OBJECTIVES

The autopsy is considered the gold standard in death investigation. Performing an autopsy requires human and material resources that must be programmed in order to meet the demands of the judicial system. However, as far as we know, the cost of forensic autopsy in Spain has not been determined. Thus, the aim of this study was to estimate the cost of a standard autopsy in order to organise Forensic Pathology Services more efficiently.

MATERIAL AND METHODS

A micro-cost analysis was carried out. The nominal group technique was applied using a panel of 10 forensic experts in order to identify and quantify the resources associated with a forensic autopsy.

RESULTS

The results showed that analysis and studies are the most important item in the total cost (54.7%), followed by staff (20.5%), preservation of body (14%), single-use products (7%), equipment and stock (1.6%), cleaning and disinfection (1.5%), facilities maintenance (0.5%) and IT (0.2%).

CONCLUSIONS

The total cost of a standard autopsy was €1501.45, which is lower than the European average. This study is the first in Spain to calculate the unit price of a forensic autopsy by means of micro-cost analysis. This may help to address the way forensic pathology centres are organised at different levels of complexity.

Informed consent of postmortem sampling: Bibliographic review

Background

Informed consent is based on the principle of personal autonomy, the moral conception of respect for the dignity of the human being and therefore on his freedom. The rest of the universal bioethical principles are articulated in the informed consent process: non-maleficence, justice, and beneficence.

Objective

Establish the situations in which it is pertinent to apply informed consent in the taking of postmortem samples from a bioethical approach versus a legal approach.

Methodology

A review was carried out in: SCIELO, LILACS, IBECS, CUMED, NIH, Repository of the Pan American Health Organization; using keywords: informed consent, human rights, autonomy, bioethics, autopsy, post-mortem samples and forensic doctors and a combination of these. The inclusion criteria: articles with a maximum age of five years, in Spanish and English with free access.

Results

113 articles were obtained using the keywords and their combinations, plus another 43 additional records identified from other sources such as laws, regulations, etc. By eliminating the sources: duplicates, not relevant, disabled, and incomplete, a total of 49 articles were worked on.

Conclusions

There is a need to include in the national and international ethical guidelines that regulate scientific research and guidelines to follow on the completion of the informed consent process in studies that involve postmortem samples, after their primary use.

The cost-effectiveness of antenatal and postnatal education and support interventions for women aimed at promoting breastfeeding in the UK

Background

Breastfeeding is associated with health benefits to mothers and babies and cost-savings to the health service. Breastfeeding rates in the UK are low for various reasons including cultural barriers, inadequate support to initiate and sustain breastfeeding, lack of information, or choice not to breastfeed. Education and support interventions have been developed aiming at promoting breastfeeding rates. The objective of this study was to assess the cost-effectiveness of such interventions for women, initiated antenatally or in the first 8 weeks postnatally, aiming at improving breastfeeding rates, in the UK.

Methods

A decision-analytic model was constructed to compare costs and quality-adjusted life-years (QALYs) of a breastfeeding intervention from the perspective of health and personal social services in England. Data on intervention effectiveness and the benefits of breastfeeding were derived from systematic reviews. Other model input parameters were obtained from published sources, supplemented by expert opinion.

Results

The incremental cost-effectiveness ratio (ICER) of the modelled intervention added on standard care versus standard care was £51,946/QALY, suggesting that the intervention is not cost-effective under National Institute for Health and Care Excellence (NICE) criteria in England. Sensitivity analysis suggested that the cost-effectiveness of the intervention improved as its effectiveness increased and intervention cost decreased. At the base-case effect (increase in breastfeeding rates 16–26 weeks after birth by 19%), the intervention was cost-effective (<£20,000/QALY) if its cost per woman receiving the intervention became ≈£40–£45. At the base-case cost (£84), the intervention was cost-effective if it increased breastfeeding rates by at least 35–40%.

Conclusions

Available breastfeeding interventions do not appear to be cost-effective under NICE criteria in England. Future breastfeeding interventions need to have higher effectiveness or lower cost compared with currently available interventions in order to become cost-effective. Public health and other societal interventions that protect, promote and support breastfeeding may be key in improving breastfeeding rates in the UK.

Unifying the death notification form: Recommendations by the Saudi Health Council task force

Objectives

Death reporting and certification forms are essential elements of a country's healthcare policies. KSA faces several challenges regarding death reporting and certification. This study aims to provide recommendations to unify death notifications in Saudi Arabia.

Methods

In 2019, the General Secretariat of the Saudi Health Council designed a qualitative research project that aimed to provide recommendations to unify death notifications. The council convened a task force of physicians and healthcare administrators to design and conduct qualitative research to review the Saudi Health Council's policies related to death certification and investigate potential methods of improvement. In addition, the task force performed an extensive review of the literature and current practices in KSA.

Results

The task force proposed a set of robust recommendations to correct the issues affecting the current systems of death reporting and certification.

Conclusions

This report presents the working methodology and recommendations of the task force.

Comparison of conventional autopsy with post-mortem magnetic resonance, computed tomography in determining the cause of unexplained death

Conventional autopsy is the gold standard for identifying unexplained death but due to declines in referrals, there is an emerging role for post-mortem imaging. We evaluated whether post-mortem magnetic resonance (PMMR) and computed tomography (PMCT) are inferior to conventional autopsy. Deceased individuals ≥ 2 years old with unexplained death referred for coronial investigation between October 2014 to December 2016 underwent PMCT and PMMR prior to conventional autopsy. Images were reported separately and then compared to the autopsy findings by independent and blinded investigators. Outcomes included the accuracy of imaging modalities to identify an organ system cause of death and other significant abnormalities. Sixty-nine individuals underwent post-mortem scanning and autopsy (50 males; 73%) with a median age of 61 years (IQR 50-73) and median time from death to imaging of 2 days (IQR 2-3). With autopsy, 48 (70%) had an organ system cause of death and were included in assessing primary outcome while the remaining 21 (30%) were only included in assessing secondary outcome; 12 (17%) had a non-structural cause and 9 (13%) had no identifiable cause. PMMR and PMCT identified the cause of death in 58% (28/48) of cases; 50% (24/48) for PMMR and 35% (17/48) for PMCT. The sensitivity and specificity were 57% and 57% for PMMR and 38% and 73% for PMCT. Both PMMR and PMCT identified 61% (57/94) of other significant abnormalities. Post-mortem imaging is inferior to autopsy but when reported by experienced clinicians, PMMR provides important information for cardiac and neurological deaths while PMCT is beneficial for neurological, traumatic and gastrointestinal deaths.

Autopsy Patients With Obesity or Metabolic Syndrome as Basic Cause of Death: Are There Pathological Differences Between These Groups?

Background:

The objectives of this study were the evaluation of pathological characteristics of patients with obesity or metabolic syndrome (MS) as basic cause of death, associating the autopsy findings with some clinical aspects and the abdominal adipose panicle thickness.

Methods:

A total of 88 autopsy cases were studied, divided into 2 groups based on the main cause of death: group 1 (n = 15) obesity and group 2 (n = 73) MS. Clinical summaries of autopsy requests, macroscopic findings, and histologic sections were reviewed.

Results:

The definition of obesity as the basic cause of death is associated with larger thickness of the abdominal adipose panicle, being 8.5 cm (P = .001) the best measurement, according to the receiver operating characteristic curve. Hypertensive cardiopathy (P = .001), ischemic cardiopathy (P = .003), coronary (P = .008)/systemic (P = .005) atherosclerosis, and arterial (P = .014)/arteriolar (P = .027) nephrosclerosis are associated with the diagnosis of MS. Steatohepatitis is associated with the diagnosis of obesity (P = .030); however, its association with the thickness of the abdominal adipose panicle is not statistically significant (P = .211).

Conclusions:

In the context of an obese patient in autopsy, pathologist may use the information about abdominal adipose panicle associated with heart, kidney, and liver findings, even macroscopic ones, to decide the basic cause death between obesity and MS.
