Using case vignettes to study the presence of outcome, hindsight, and implicit bias in acute unplanned medical care: a cross-sectional study.

BACKGROUND AND IMPORTANCE: Various biases can impact decision-making and judgment of case quality in the Emergency Department (ED). Outcome and hindsight bias can lead to wrong retrospective judgment of care quality, and implicit bias can result in unjust treatment differences in the ED based on irrelevant patient characteristics. OBJECTIVES: First, to evaluate the extent to which knowledge of an outcome influences physicians' quality of care assessment. Secondly, to examine whether patients with functional disorders receive different treatment compared to patients with a somatic past medical history. DESIGN: A web-based cross-sectional study in which physicians received case vignettes with a case description and care provided. Physicians were informed about vignette outcomes in a randomized way (no, good, or bad outcome). Physicians rated quality of care for four case vignettes with different outcomes. Subsequently, they received two more case vignettes. Physicians were informed about the past medical history of the patient in a randomized way (somatic or functional). Physicians made treatment and diagnostic decisions for both cases. SETTING AND PARTICIPANTS: One hundred ninety-one Dutch emergency physicians (EPs) and general practitioners (GPs) participated. OUTCOME MEASURES AND ANALYSIS: Quality of care was rated on a Likert scale (0-5) and dichotomized as adequate (yes/no). Physicians estimated the likelihood of patients experiencing a bad outcome for hindsight bias. For the second objective, physicians decided on prescribing analgesics and additional diagnostic tests. MAIN RESULTS: Large differences existed in rated quality of care for three out of four vignettes based on different case outcomes. For example, physicians rated the quality of care as adequate in 44% (95% CI 33-57%) for an abdominal pain case with a bad outcome, compared to 88% (95% CI 78-94%) for a good outcome, and 84% (95% CI 73-91%) for no outcome ( P  < 0.01). The estimated likelihood of a bad outcome was higher if physicians received a vignette with a bad patient outcome. Fewer diagnostic tests were performed and fewer opioids were prescribed for patients with a functional disorder. CONCLUSION: Outcome, hindsight, and implicit bias significantly influence decision-making and care quality assessment by Dutch EPs and GPs.

[Retrospective study of 20 years of post-mortem examination of young adults]. / De meerwaarde van postmortaal onderzoek.

OBJECTIVE: This study is designed to gain insight into the cause of death in deceased young adults, by analyzing autopsies and other post-mortem examinations including their contribution into finding the cause of death DESIGN: Retrospective cohort study. METHOD: Included were adults aged between 18-45 years old who underwent a clinical autopsy at the Isala Klinieken in Zwolle between January 2000 and October 2022. Included patients had a natural cause of deaths and were divided into two categories: expected and unexpected deaths. For each patient the post-mortem examination and their contribution to diagnose the cause of death were determined, among other things. Collected data was processed in a database and analyzed. RESULTS: Between January 2000 and October 2022, 212 autopsies were performed in the 18-45 age group. Of these 212 patients, 54 (25,5%) were expected deaths and 158 (74,5%) unexpected deaths. 116 patients had an unknown cause of death (7 expected vs. 109 unexpected). After post-mortem examination, this number has decreased to 15 deaths (expected 0 vs. unexpected 15). This is a reduction form 54,7% to 7,1%. Of the 96 presumed diagnoses/causes of death for autopsy, 16 (16,7%) cases were reclassified as Goldman score 1 discrepancies. CONCLUSION: Performing post-mortem examinations contributes to reducing the number of unknown causes of death. Post-mortem examinations also provide knowledge about illnesses, the clinical course of syndromes and the actual cause of death in (young) adults, even when mortality is expected.

[Hardly any objection from patients against medical information feedback among healthcare workers in the acute care]. / Nauwelijks bezwaar van SEH-patiënten tegen terugkoppeling medische gegevens.

OBJECTIVE: Feedback of patients' medical information among healthcare workers within the acute care could improve the quality of care during an Emergency Department (ED) visit. However, in practice, feedback among healthcare workers leads to juridical discussions. Therefore, this study explores whether ED patients agree with medical information feedback among healthcare workers in the acute care, such as the ambulance staff and ED physicians, and whether this was different from permission for feedback to the general practitioner. METHOD: Multicenter cross-sectional study in three EDs in the Netherlands. Patients ≥18 years old, presented per ambulance between May 3rd and June 12th 2021, filled in a questionnaire asking whether they agree with medical information feedback to ambulance staff and reviewing medical files for follow-up by ED physicians. RESULTS: A total of 369 patients were included with a mean age of 68 years (SD 18). In total, 98,9% of patients agreed with medical information feedback to ambulance staff, which was not significantly different from the 99,2% of patients who agreed with feedback to the general practitioner (p=1.00). CONCLUSION: All but a few ED patients agreed with medical information exchange to ambulance personnel and follow-up by ED-physicians. During ED-visits, medical information feedback to the general practitioner is a standard procedure, with the possibility of an opt-out. In our opinion, feedback and exchange of medical information within the acute care should be arranged similarly.

High prevalence of non-accidental trauma among deceased children presenting at Level I trauma centers in the Netherlands.

PURPOSE: Between 0.1-3% of injured children who present at a hospital emergency department ultimately die as a result of their injuries. These events are typically reported as unnatural causes of death and may result from either accidental or non-accidental trauma (NAT). Examples of the latter include trauma that is inflicted directly or resulting from neglect. Although consultation with a forensic physician is mandatory for all deceased children, the prevalence of fatal inflicted trauma or neglect among children is currently unclear. METHODS: This is a retrospective study that included children (0-18 years) who presented and died at one of the 11 Level I trauma centers in the Netherlands between January 1, 2014, and January 1, 2019. Outcomes were classified based on the conclusions of the Child Abuse and Neglect team or those of forensic pathologists and/or the court in cases referred for legally mandated autopsies. Cases in which conclusions were unavailable and there was no clear accidental cause of death were reviewed by an expert panel. RESULTS: The study included 175 cases of childhood death. Seventeen (9.7%) of these children died due to inflicted trauma (9.7%), 18 (10.3%) due to neglect, and 140 (80%) due to accidents. Preschool children (< 5 years old) were significantly more likely to present with injuries due to inflicted trauma and neglect compared to older children (44% versus 6%, p < 0.001, odds ratio [OR] 5.80, 95% confidence interval [CI] 2.66-12.65). Drowning accounted for 14 of the 18 (78%) pediatric deaths due to neglect, representing 8% of the total cases. Postmortem radiological studies and autopsies were performed on 37 (21%) of all cases of childhood death. CONCLUSION: One of every five pediatric deaths in our nationwide Level I trauma center study was attributed to NAT; 44% of these deaths were the result of trauma experienced by preschool-aged children. A remarkable number of fatal drownings were due to neglect. Postmortem radiological studies and autopsies were performed in only one-fifth of all deceased children. The limited use of postmortem investigations may have resulted in missed cases of NAT, which will result in an overall underestimation of fatal NAT experienced by children.

Amsterdam Research Initiative for Sub-surface Taphonomy and Anthropology (ARISTA) - A taphonomic research facility in the Netherlands for the study of human remains.

A taphonomic research facility for the study of human remains was recently realized in Amsterdam, the Netherlands, to systematically investigate the decomposition of the human body under known conditions. Governmental authorization was obtained to make use of the body donation program of the Amsterdam University Medical Centers, location Academic Medical Center, for this specific purpose. In contrast to the small number of comparable initiatives elsewhere, this facility specifically allows for the study of buried bodies e.g. with the use of telemetry and remote sensing. Here, we discuss the concept of body donation in the Netherlands, its role in taphonomic research, and the sequence of events that preceded the realization of this facility, which is the first of its kind in Europe. In addition to offering novel research options to the scientific community, we hope that it will also pave the way for the successful realization of similar initiatives in other locations.

The risk of emerging new psychoactive substances: The first fatal 3-MeO-PCP intoxication in The Netherlands.

Structural analogs of classic drugs, also called designer drugs, are a booming market due to the easy accessibility on the internet and their legal status. One of those 'legal highs' is an analog of phencyclidine, namely 3-methoxyphencyclidine (3-MeO-PCP). Very few fatalities have been reported where 3-MeO-PCP contributed to the death of an individual. We present the first fatal case in the Netherlands and one of the few worldwide. Postmortem biological samples and the presumed abused unknown substance, sold as ant poison, were obtained. 3-MeO-PCP was detected, and the resulting concentration was 152 µg/l in whole blood. The presumed taken unknown sample was identified as 3-MeO-PCP and thus linked to the victim. The cause of death was a combination of 3-MeO-PCP, amphetamine, and alcohol. Improved diagnostic skills are necessary to face these emerging novel psychoactive substances also in light of public health and social risks.

The correlation between the Aquatic Decomposition Score (ADS) and the post-mortem submersion interval measured in Accumulated Degree Days (ADD) in bodies recovered from fresh water.

The Aquatic Decomposition Score (ADS) made by van Daalen et al., was developed to approximate the Post-Mortem Submersion Interval (PMSI) in bodies recovered in salt water. Since the decomposition process in salt water differs from the process in fresh water due to salinity, the temperature, and the depth of the water, we wanted to investigate whether there is a correlation between the ADS and the PMSI and if the ADS can be used to make an estimation of the PMSI in bodies recovered from fresh water. For the latter, the PMSI was measured using Accumulated Degree Days (ADD). In our study we included seventy-six human remains found outdoors in fresh water. Their decomposition was measured using the ADS. A strong correlation was found between the ADS and the PMSI. Also, it was found that the ADS can significantly estimate the ADD. Despite the more varied circumstances under which bodies in fresh water are found when compared to those found in salt water, the ADS can be used to measure the decomposition and accurately estimate the ADD, and thus the PMSI. More research is needed to validate our method and make a prediction model with smaller confidence intervals.

The value of postmortem computed tomography in paediatric natural cause of death: a Dutch observational study.

BACKGROUND: Postmortem CT is a relatively new field of interest within paediatric radiology. This paper focusses on its value in cases of unexpected natural death. OBJECTIVE: We report on an observational Dutch study regarding the value of postmortem CT in children with an assumed natural unexpected death because postmortem CT is part of the Dutch NODO (additional investigations of cause of death) procedure. MATERIALS AND METHODS: We included consecutive children who fulfilled criteria for the NODO procedure and were therefore referred to one of the centres for the procedure. Postmortem CT was performed in all cases and skeletal survey was performed in all children ages <5 years. The cause of death was defined in a consensus meeting. RESULTS: We included a total of 54 children (30 boys, median age 1.1 years, and 24 girls, median age 0.8 years). A definitive cause of death was established in 38 cases. In 7 cases the cause of death could be identified on postmortem CT. In 7 cases imaging findings were clinically relevant but did not lead to a cause of death. In the remaining 40 cases postmortem CT did not add to the diagnostic workup. CONCLUSION: Our study shows that in a group of children who unexpectedly died of an assumed natural cause of death and in whom a cause of death was found at autopsy, postmortem CT detected the cause of death in a minority of cases (12.9%). In the majority of cases (74.1%) postmortem CT did not add value in diagnosing the cause of death.

Subdural hematomas: glutaric aciduria type 1 or abusive head trauma? A systematic review.

PURPOSE: Glutaric aciduria type 1 (GA1) is a rare metabolic disorder of glutaryl-CoA-dehydrogenase enzyme deficiency. Children with GA1 are reported to be predisposed to subdural hematoma (SDH) development due to stretching of cortical veins secondary to cerebral atrophy and expansion of CSF spaces. Therefore, GA1 testing is part of the routine work-up in abusive head trauma (AHT). This systematic review addresses the coexistence of GA1 and SDH and the validity of GA1 in the differential diagnosis of AHT. METHODS: A systematic literature review, with language restriction, of papers published before 1 Jan 2015, was performed using Pubmed, PsychINFO, and Embase. Inclusion criteria were reported SDHs, hygromas or effusions in GA1 patients up to 18 years of age. Of 1599 publications, 20 publications were included for analysis. RESULTS: In total 20 cases, 14 boys and 6 girls, were included. In eight cases (40%) a child abuse work-up was performed, which was negative in all cases. Clinical history revealed the presence of trauma in eight cases (40%). In only one case neuroradiology revealed no abnormalities related to GA1 according to the authors, although on evaluation we could not exclude AHT. CONCLUSION: From this systematic review we conclude that SDHs in 19/20 children with GA1 are accompanied by other brain abnormalities specific for GA1. One case with doubtful circumstances was the exception to this rule.
