Homicide Manner-of-Death Classification in Arrest-Related Death.

ABSTRACT: Multiple studies have documented various factors that influence or determine forensic pathologist classification of manner of death. There do not appear to be any published studies on manner of death classification specifically regarding arrest-related deaths (ARDs). The goal of this study was to consider a large body of cases of nonfirearm ARDs to analyze the homicide classification with regards to numerous decedent and practitioner (medical examiner/coroner [ME/C]) variables. We analyzed 1145 US autopsy reports from the years 2006-2020, inclusive, and considered decedent variables of age, ethnicity, height, weight, body mass index, toxicology, and mention of a conducted electrical weapon and ME/C influence variables of gender, country region, and year. We found that the homicide classification likelihood increased by a factor of 1.04-1.05 per year, 1.34-1.37 for a female medical examiner, and 1.4-1.5 going from Southern states to Western states. There is an increasing trend for ME/C to label nonfirearm ARDs as homicides in the United States. The homicide classification is more common in Western states and less common in Southern states, and it was more common with a female ME/C.

Impact of Covid-19 pandemic on volume and surgeon professional fees generated by emergency general surgery procedures.

INTRODUCTION: The COVID-19 pandemic has changed the dynamics of healthcare in the USA. In early 2020, most states issued orders to stop non-emergent elective surgeries. This contracted the overall revenue generated by the hospital systems. The impact of COVID-19 pandemic on volume has not been well studied but effects on surgeon professional fees generated remains unexplored. The goal of this study was to assess if COVID-19 pandemic has affected surgeon professional fees and revenues generated from emergency general surgeries. METHODS: This is a retrospective review to compare surgical case volume in 2019 and 2020. We obtained our data from a tertiary care referral center database. Data were collected from February to April of 2019 and 2020, corresponding to the duration of statewide ban on non-emergent surgical cases. We used the most reported current procedural terminology (CPT) Code for each surgical procedure to calculate the surgeon professional fees generated. We calculated the percentage difference in surgeon professional fees between 2019 and 2020 for comparison. RESULTS: There was a statistically significant decrease in daily emergent operations between 2019 and 2020 time periods (6.13/day vs 4.64/day). There was a statistically significant decrease in hospital admissions for appendicitis, cholecystitis, diverticulitis, skin and soft tissue infections, small bowel obstruction and GI bleed. Additionally, a statistically significant decrease in number of appendectomy, cholecystectomy, sigmoid colectomy with anastomosis, small bowel resection, operation for incarcerated and reducible hernia procedures was observed. There is a decline in surgeon professional fees generated in 2020 compared to 2019 for all emergent surgeries. When compared to 2019, we observed an increase of 238 more inquests in February to April of 2020, which is the same time period when we noticed a significant decrease in hospital admissions and procedures for emergency general surgery. CONCLUSION: The COVID-19 pandemic has negatively impacted surgical case volumes in 2020 compared to 2019. This includes both emergent and non-emergent cases. There is a need for more broad cost analysis which considers hospital expenditures and cost benefit analysis.

Learning from suicide deaths in Harris County, Texas.

This study examined individual and community demographic characteristics surrounding suicides in one of the most populous counties in the United States. We paired medical examiner records with U.S. Census data and analyzed them using geospatial software. The majority of decedents were non-Hispanic, white males who died primarily of gunshot wounds. Salient age characteristics included interpersonal violence and depression among ages younger than 40. Despite lower incomes and education levels, areas with higher population density and racial/ethnic minorities had fewer suicides. Additional research should address depression among males and the elderly, interpersonal violence, firearm access, and culture.

Nontraumatic In-Custody Homicidal Deaths in Harris County, Texas (2015-2019): Justification for a Separate Manner of Death Category.

ABSTRACT: A subset of in-custody deaths, typically occurring in the precustody phase, arise from a combination of mechanisms, rather than a single anatomically or circumstantially demonstrable cause. This case series examined nontraumatic in-custody deaths that occurred over a 5-year period (2015-2019) in Harris County, Texas. Cases were identified as "in custody" or "during police intervention," with a homicide manner; traumatic causes of death (eg, police shootings) were excluded.Sixteen cases were identified. The median age was 40 years, with an interquartile range of 35 to 50.5 years. All but one were male, and there were 8 (50%) Black, 5 (31%) White, and 1 (6%) Hispanic cases. Intoxicants were detected in all except 1 death that occurred after a prolonged hospitalization; stimulants were identified in 12 (75%). The cause of death for each was descriptive, representing the complex interplay of external forces with physiologic/toxicologic and disease-related mechanisms.This series is used as a backdrop for a discussion regarding the inadequacy of the current 5-category manner of death classification scheme and to suggest an alternative category of manner. This alternative category, specifically "legal intervention," would be most useful for this subset of nontraumatic in-custody deaths but may have applicability for other types of in-custody deaths.

Establishing a Regional Trauma Preventable/Potentially Preventable Death Rate.

OBJECTIVE: To establish a trauma preventable/potentially preventable death rate (PPPDR) within a heavily populated county in Texas. SUMMARY: The National Academies of Sciences estimated the trauma preventable death rate in the United States to be 20%, issued a call for zero preventable deaths, while acknowledging that an accurate preventable death rate was lacking. In this absence, effective strategies to improve quality of care across trauma systems will remain difficult. METHODS: A retrospective review of death-related records that occurred during 2014 in Harris County, TX, a diverse population of 4.4 million. Patient demographics, mechanism of injury, cause, timing, and location of deaths were assessed. Deaths were categorized using uniform criteria and recorded as preventable, potentially preventable or nonpreventable. RESULTS: Of 1848 deaths, 85% had an autopsy and 99.7% were assigned a level of preventability, resulting in a trauma PPPDR of 36.2%. Sex, age, and race/ethnicity varied across preventability categories (P < 0.01). Of 847 prehospital deaths, 758 (89.5%) were nonpreventable. Among 89 prehospital preventable/potentially preventable (P/PP) deaths, hemorrhage accounted for 55.1%. Of the 657 initial acute care setting deaths, 292 (44.4%) were P/PP; of these, hemorrhage, sepsis, and traumatic brain injury accounted for 73.3%. Of 339 deaths occurring after initial hospitalization, 287 (84.7%) were P/PP, of these 117 resulted from sepsis and 31 from pulmonary thromboembolism, accounted for 51.6%. CONCLUSIONS: The trauma PPPDR was almost double that estimated by the National Academies of Sciences. Data regarding P/PP deaths offers opportunity to target research, prevention, intervention, and treatment corresponding to all phases of the trauma system.

Establishing a regional pediatric trauma preventable/potentially preventable death rate.

PURPOSE: Although trauma is the leading cause of death for the pediatric population, few studies have addressed the preventable/potentially preventable death rate (PPPDR) attributable to trauma. METHODS: This is a retrospective study of trauma-related death records occurring in Harris County, Texas in 2014. Descriptive and Chi-squared tests were conducted for two groups, pediatric and adult trauma deaths in relation to demographic characteristics, mechanism of injury, death location and survival time. RESULTS: There were 105 pediatric (age < 18 years) and 1738 adult patients. The PPPDR for the pediatric group was 21.0%, whereas the PPPDR for the adult group was 37.2% (p = 0.001). Analysis showed fewer preventable/potentially preventable (P/PP) deaths resulting from any blunt trauma mechanism in the pediatric population than in the adult population (19.6% vs. 48.4%, p < 0.001). Amongst the pediatric population, P/PP traumatic brain injury (TBI) were more common in the youngest age range (age 0-5) vs. the older (6-12 years) pediatric and adolescent (13-17 years) patients. CONCLUSION: Our results identify areas of opportunities for improving pediatric trauma care. Although the overall P/PP death rate is lower in the pediatric population than the adult, opportunities for improving initial acute care, particularly TBI, exist.

Postmortem genetic screening for the identification, verification, and reporting of genetic variants contributing to the sudden death of the young.

Each year in the United States, thousands of cases of sudden and unexpected deaths of infants, children, and young adults are assigned an undetermined cause of death after postmortem investigation and autopsy. Heritable genetic variants have been suggested as the cause of up to a third of sudden death (SD) cases. Elucidation of the genetic variants involved in SD cases is important to not only help establish cause and manner of death of these individuals, but to also aid in determining whether familial genetic testing should be considered. Previously, these types of postmortem screenings have not been a feasible option for most county medical examiners' and coroners' offices. We sequenced full exons of 64 genes associated with SD in the largest known cohort (351) of infant and young SD decedents using massively parallel sequencing at <$600 per sample. Genetic variants were assessed through literature review and clinical evaluation by a multidisciplinary consortium of experts. Thirteen individuals (3.7%), eight infants (2.8% of those <1 yr of age) and five children/young adults (7.0% of those >1 yr of age), were found to have a reportable genetic variant contributing to SD. These percentages represent an estimate lower than those previously reported. Overall yields and results likely vary between studies due to differences in evaluation techniques and reporting. Additionally, we recommend ongoing assessment of data, including nonreported novel variants, as technology and literature continually advance. This study demonstrates a strategy to implement molecular autopsies in medicolegal investigations of young SD decedents.

A Descriptive and Geospatial Analysis of Environmental Factors Attributing to Sudden Unexpected Infant Death.

This study examined medicolegal death investigation records and autopsy reports of a medical examiner's office to identify the circumstances surrounding sudden unexpected infant deaths (SUID) and geospatial analyses to pinpoint areas of infant death concentration. Analysis of 732 records of SUID deaths occurring in a 10-year span resulted in the conclusion that environmental factors associated with the sudden death were to some extent modifiable. Co-sleeping (sharing a sleeping surface, or bed-sharing) on various surfaces (mattress, pallet, couch) occurred in 53.4% of the infant deaths. Geographic areas where the largest number of deaths occurred were characterized as areas of high poverty level. The inclusion of additional information at the time of investigation (eg, alcohol and tobacco use of co-sleepers, illness of others in household, exceptions to normal sleep routine of infant) may aid in identifying modifiable circumstances to reduce infant mortality attributable to sudden infant death.

Improving medicolegal death investigative gaps of fatal elder abuse.

The purpose of this brief is to present several case vignettes that illustrate omissions in the investigation of elder deaths. These vignettes demonstrate the need for a standardized approach in the conduct of medicolegal investigations of fatal elder abuse. For each of the described oversights, a recommendation is offered to address the gap in investigation processes, which in turn could improve the determination of cause and manner of elder death. Inherent limitations of resources and practical realities of death investigation are discussed and recommendations are made for future research. Viewed broadly, deficiencies in elder death investigations can lead to the underreporting of elder abuse and the reduction of legal options for victims, which may reflect a systemic pattern of social injustice.

Ethical Considerations on Disclosure When Medical Error Is Discovered During Medicolegal Death Investigation.

In the course of fulfilling their statutory role, physicians performing medicolegal investigations may recognize clinical colleagues' medical errors. If the error is found to have led directly to the patient's death (missed diagnosis or incorrect diagnosis, for example), then the forensic pathologist has a professional responsibility to include the information in the autopsy report and make sure that the family is appropriately informed. When the error is significant but did not lead directly to the patient's demise, ethical questions may arise regarding the obligations of the medical examiner to disclose the error to the clinicians or to the family. This case depicts the discovery of medical error likely unrelated to the cause of death and describes one possible ethical approach to disclosure derived from an ethical reasoning model addressing ethical principles of respect for persons/autonomy, beneficence, nonmaleficence, and justice.

Suicide Within 72 Hours After Discharge From Health Care Settings: Decedent Characteristics.

Health care providers have the challenge of identifying patients at risk of committing suicide after discharge from their care. The aim of this study was to identify and describe the population committing suicide less than 72 hours after discharge from medical care. Between 2006 and 2014 in Harris County, Texas, 30 individuals were identified who met these criteria. The decedents included 27 men and 3 women with a mean age of 43.5 years. The cause of death in most cases was gunshot wound of the head. Five of the decedents had requested discharge or left against medical advice and 24 committed suicide within 24 hours. Although the sample size is small, it is one of the largest cohorts of its type.

The silent killer: Previously undetected pulmonary emboli that result in death after discharge.

INTRODUCTION: Pulmonary embolism (PE) is a recognized cause of death in hospitalized trauma patients, yet less is known about PE after discharge. PATIENTS & METHODS: All post-discharge, autopsy-demonstrated, fatal PE resulting from trauma within a large US county over six years were analyzed. Counts, percentages, mean values, SD, and IQR were calculated for all variables. RESULTS: 1848 trauma deaths were reviewed, of which 85% had an autopsy. Eighty-five patients died from PE after discharge from their initial injury. 53% were initially treated at non-trauma centers, and 9% did not seek medical assistance. 75% were injured by falling, and most injuries occurred in the lower extremities. 86% had an ISS <16, but 87% needed assistance or were bed-bound after injury, despite 75% having no mobility limitations before the injury. 53% died within one month of injury, and 91% within the first year. Before death, only 11% were prescribed chemical thromboprophylaxis or an antiplatelet agent, and only 8% were diagnosed with venous thromboembolism before death. CONCLUSIONS: Fatal PE after discharge typically occurred following activity-limiting lower extremity injuries with an ISS<16.

Geospatial Analysis of Prehospital Triage and Early Potential Preventable Traumatic Deaths.

Severely injured patients often depend on prompt prehospital triage for survival. This study aimed to examine the under-triage of preventable or potentially preventable traumatic deaths. A retrospective review of Harris County, TX, revealed 1848 deaths within 24 hours of injury, with 186 being preventable or potentially preventable (P/PP). The analysis evaluated the geospatial relationship between each death and the receiving hospital. Out of the 186 P/PP deaths, these were more commonly male, minority, and penetrating mechanisms when compared with NP deaths. Of the 186 PP/P, 97 patients were transported to hospital care, 35 (36%) were transported to Level III, IV, or non-designated hospitals. Geospatial analysis revealed an association between the location of initial injury and proximity to receiving Level III, IV, and non-designated centers. Geospatial analysis supports proximity to the nearest hospital as one of the primary reasons for under-triage.

Contextual information in medicolegal death investigation decision-making: Manner of death determination for cases of a single gunshot wound.

To explore the role of contextual information in determining manner of death, four cases involving single gunshot wounds were presented to participants (n = 252) involved in medicolegal death investigation. The participants received identical autopsy information but different contextual information. The data demonstrated that participants tended to rely on contextual information more than autopsy information: In the suicide context, participants across the four cases reached 153 final decisions of suicide (and 25 of homicide), whereas in the homicide context, participants reached only 10 final decisions of suicide (and 181 of homicide) --all while examining identical autopsy information. The impact of the contextual information was so powerful that many participants changed initial autopsy-based conclusions to align with the contextual information. Given the significant role and impact that contextual information has on expert decision making, one must consider what, how, and when contextual information should be used.

An Analysis of Traumatic and Non-Traumatic Hemopericardium Using Autopsy Data From a County Medical Examiner.

The volume of hemopericardium requiring hemodynamic changes in the trauma patient is not well understood. We performed a study using autopsy data from trauma patients who died with hemopericardium (>20 mL). Of 1848 traumatic deaths, 54 had hemopericardium at autopsy. The median pericardial blood in this group was 150 mL, which is more than the previously assumed volume to be lethal in trauma patients. Therefore, it may be appropriate to redefine the estimated volume required to cause lethal hemopericardium in trauma patients.

Preservation of evidence during pediatric organ donation: a modified thoracotomy procedure designed to increase consent in medical examiner cases.

Deceased potential organ donors are often under the jurisdiction of medical examiners/ coroners. In these deaths, the medical examiner/coroner has the statutory responsibility of determining cause and manner of death but is also responsible for presenting findings from the complete autopsy in court. The ability to analyze findings such as location, nature, and age of rib fractures and patterned skin injuries may be crucially important to legal disposition, even though those findings may not be critical to determination of cause and/or manner of death. Potential alteration or destruction of those findings is one reason why a medical examiner/coroner may deny organ donation. We present here a modified surgical approach to accessing thoracic organs in children so that posterior rib fractures, which have particular significance in child abuse cases, can be preserved unaltered for subsequent autopsy. This simple modification of surgical technique has greatly facilitated the mutual goals of the medical examiner and the designated organ procurement organization in our jurisdiction, and it has thus decreased the frequency of denials of organ donation.

Identifying gaps and improving investigation of fatal elder abuse and/or neglect.

Death investigator and autopsy reports for decedents 65 years and older within a major metropolitan area over a five-year period were assessed for the possibility of elder abuse and/or neglect. The study consisted of two stages. A simple two-question screening criteria was used to determine whether the decedent was (1) dependent on another for at least one activity of daily living and (2) had a presence of at least one indicator of abuse and/or neglect. Second, only cases with affirmative criteria responses were reviewed to identify inconsistent or deficient variables that precluded (or if present, allowed) determination of abuse and/or neglect. A multidisciplinary panel of local and national experts, including forensic pathologists, law enforcement, and geriatricians assessed these indicators as indicative of presence of abuse/neglect, and these indicators were subsequently developed as a supplemental data collection tool. Of a possible 2798 cases, 2324 (83%) were excluded using the screening criteria. This reduced the number of cases that warranted further investigation to 474 (17% of elderly deaths in this timeframe). All 474 decedents were dependent on another for at least one ADL and 322 (68%) had unexplained injuries. In 180 (38%) cases had recorded notation of a suspicion of abuse and/or neglect at the time of death. The results support the premise that a simple, two-criterion screening can effectively identify cases of potential abuse and/or neglect and, when followed by a supplemental data collection tool, cases can be efficiently evaluated.

Quality Assurance Through Standard Operating Procedures Development and Deviation: A Medicolegal Death Investigation Systems Response to the COVID-19 Pandemic.

ABSTRACT: Standard operating procedures drive everyday practice within any organization, including those within a forensic setting. In the event of unusual circumstances, organizations must respond rapidly to address the impact on operations while ensuring that the quality and safety outcomes of routine services are not affected. This case study illustrates how standard operating procedures can be newly developed or modified, and rapidly deployed and quickly revised, to address unusual circumstances. The response to the COVID-19 pandemic is used as an example in this case report.

Fatal and Nonfatal Injury Patterns of Stranded Motorists.

ABSTRACT: Because nonfatal and fatal incidents for stranded motorists are not separated from vehicular accidents, little data are available on incident characteristics. To close this gap, data fields were inserted into databases at a medical examiner's office and two trauma centers to collect injury-related information. Forensic nurses and pathologists aided in forming a collaboration among the agencies involved and supported data collection efforts. Data collected over a 5-year period were examined for injury patterns to determine risk factors affecting these patterns. Of the total sample (N = 219), 24.7% had spinal injuries resulting in fatal injuries for 46 of 54 individuals. The odds were stranded motorists with spine-related injuries (C1-C7) had 9.13 times higher risk for a fatal outcome compared with those without spine-related injuries. Severe injuries (Abbreviated Injury Scale scores ≥ 4) noted for head/neck (29.7%) and chest (24.2%) were significantly associated with fatality. Of the 219 cases, 22.8% were inside of a stopped vehicle, and 77.2% were outside a vehicle at the time of injury. Outcomes illustrated the success of the interprofessional collaboration between trauma centers and a medicolegal death investigation agency that resulted in data useful for forensic nurses and pathologists documenting evidence, emergency and trauma responding personnel in patient priority stabilization, and injury prevention specialists for highway safety programs.

When falls become fatal-Clinical care sequence.

OBJECTIVES: This study encompassed fall-related deaths, including those who died prior to medical care, that were admitted to multiple healthcare institutions, regardless of whether they died at home, in long-term care, or in hospice. The common element was that all deaths resulted directly or indirectly from injuries sustained during a fall, regardless of the temporal relationship. This comprehensive approach provides an unusual illustration of the clinical sequence of fall-related deaths. Understanding this pathway lays the groundwork for identification of gaps in healthcare needs. DESIGN: This is a retrospective study of 2014 fall-related deaths recorded by one medical examiner's office (n = 511) within a larger dataset of all trauma related deaths (n = 1848). Decedent demographic characteristics and fall-related variables associated with the deaths were coded and described. RESULTS: Of those falling, 483 (94.5%) were from heights less than 10 feet and 394 (77.1%) were aged 65+. The largest proportion of deaths (n = 267, 52.3%) occurred post-discharge from an acute care setting. Of those who had a documented prior fall, 216 (42.3%) had a history of one fall while 31 (6.1%) had ≥2 falls prior to their fatal incident. For the 267 post-acute care deaths, 440 healthcare admissions were involved in their care. Of 267 deaths occurring post-acute care, 129 (48.3%) were readmitted within 30 days. Preventability, defined as opportunities for improvement in care that may have influenced the outcome, was assessed. Of the 1848 trauma deaths, 511 (27.7%) were due to falls of which 361 (70.6%) were determined to be preventable or potentially preventable. CONCLUSION: Our data show that readmissions and repeated falls are frequent events in the clinical sequence of fall fatalities. Efforts to prevent fall-related readmissions should be a top priority for improving fall outcomes and increasing the quality of life among those at risk of falling.
