Comparing survival rates and mortality in operative versus nonoperative treatment for femoral neck fractures among Alzheimer's disease patients: A retrospective cohort study.

Introduction: Addressing femoral neck fractures resulting from ground-level falls in older adults with Alzheimer's disease (AD) involves a personalized treatment plan. There is considerable ongoing debate concerning the relative advantages and disadvantages of surgical treatment (internal fixation or arthroplasty) vs nonoperative treatment for femoral neck fractures in older persons with AD. Methods: This retrospective cohort study compared the mortality, hazard ratio, and survival rate between operative and nonoperative treatments, controlling for patients' demographic information and baseline health status. The study population consisted of Optum beneficiaries diagnosed with AD who experienced an initial femoral neck fracture claim between January 1, 2012, and December 31, 2017. Kaplan-Meier survival curves were applied to compare the treatment groups' post-fracture survival rates and mortality. Cox regression was used to examine the survival period by controlling the covariates. Results: Out of the 4157 patients with AD with femoral neck fractures, 59.8% were women (n = 2487). The median age was 81 years. The 1-year survival rate for nonoperative treatment (70.19%) was lower than that for internal fixation (75.27%) and arthroplasty treatment (82.32%). Compared with the nonoperative group, arthroplasty surgical treatment had significant lower hazard risk of death (arthroplasty hazard ratio: 0.850, 95% CI: 0.728-0.991, P < 0.05). Discussion: The findings suggest that the operative treatment group experiences higher survival rates and lower mortality rates than the nonoperative group. This paper provides insights into treatment outcomes of older adults with AD receiving medical care for femoral neck fractures.

Victimization in Unethical Unlicensed Small Residential Care Homes in the United States: The Case for Whole System Disruption.

In the United States, small residential care homes provide affordable community-based care for disabled older adults. Also called adult foster care homes, residential care facilities, group homes, or board and care homes, small residential care homes are typically private, small businesses operating in single-family dwellings that provide round-the-clock care in a home-like setting in residential neighborhoods. While most states license small residential care homes they also exist, legally and illegally, as unlicensed and unregulated operations. The quality of care in some unlicensed and unregulated small residential care homes can be questionable. Disabled older adults are targeted and victimized by unethical small residential care home operators for financial gain. This commentary highlights the need for whole system disruption to end victimization in unethical unlicensed and unregulated small residential care homes through case studies of the abuse and neglect of residents living in unethical unlicensed operations and recommends ambitious goals centered on reducing secondary financial gains and medically neglectful practices. These recommendations are at federal, state, and local levels, and include creating a federal definition of small residential care homes, increasing and coupling government incomes with state registration and employee misconduct registry checks, increasing oversight and assessment, improving temporary guardianship processes, providing avenues for reporting abuse, and developing older adult fatality review teams.

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.

A scoping review of nursing education for firearm safety.

BACKGROUND: Firearm violence, whether intentional or accidental, affects families worldwide. Nurses often encounter firearm-related injury and death with little knowledge or preparation for dealing with firearm safety issues. OBJECTIVES: The aim was to locate published research on nurse education in firearm safety and examine the preparation of nurses to deal with issues of firearm safety as a deterrent toward decreasing violence. The review included nurse perceptions of barriers and facilitators related to firearm safety in clinical situations. DESIGN: A literature scoping review for article identification, examination, and reporting was structured on the extended form of Arksey and O'Malley's 5-step design framework. DATA SOURCES: Databases CINAHL, MEDLINE, Sociological Abstracts, PsychInfo, and ERIC were searched for articles in English language published between 2010 and 2021 that included nurses in the studies' samples. REVIEW METHODS: Searches were managed via Covidence®, a literature screening and data extraction tool. Two independent reviewers screened the articles retrieved from the databases by title, abstract, and full-text review. Data from selected articles were extracted onto a spreadsheet and critically appraised for eligibility. RESULTS: A search of healthcare databases resulted in identification of 645 articles, of which 15 met inclusion criteria. Seven of the 15 articles addressed nurse firearm safety preparation, and seven related to counseling firearm safety for suicide prevention. Main barriers included lack of standardized guidelines, inadequate knowledge, and discomfort discussing firearm safety with patients and families. CONCLUSIONS: The scoping review findings show a noticeable gap: nurse education addressing firearm safety is, for all purposes, non-existent. A need exists for evidence-based training within academic curricula and across acute and behavioral healthcare settings.

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.

Rural-urban, age, and gender disparities and trends in suicide and homicide: Multistate evidence across 12 years.

PURPOSE: Few studies have simultaneously assessed age and gender trends in homicide and suicide across the rural-urban continuum. Herein, we examine geographic and demographic trends in suicide and homicide death rates by: (1) determining overall macro and disaggregated trends; (2) examining differences in trends based on rural-urban county classification; and (3) identifying differences in stratified trends among age and gender classifications. METHODS: A retrospective study design used suicide and homicide data (n = 199,456) from years 2005to 2017 across 16 US states. Suicide and homicide deaths were grouped by age, gender, and rural-urban classification for descriptive analyses, and trends were analyzed using Joinpoint trend analysis software. FINDINGS: Violence resulted in 142,470 suicide and 56,986 homicide deaths between 2005 and 2017. Among both males and females, overall macro trends of suicide and homicide rates generally increased with greater rurality, and trends in rural rates differed from those in nonrural areas. Joinpoint trend analysis revealed significant increases in male suicide rates in large metropolitan (1.66%), micropolitan (1.78%), and rural areas (1.77%); female suicide rates in large metropolitan (2.17%), small metropolitan (3.25%), and micropolitan areas (3.26%); male homicide rates in large metropolitan areas (10.19%); and female homicide rates in rural areas (8.29%). Finally, when stratified by age, several significant trends were found, including increases in suicide rates among females aged 64 and older in rural areas (11.71%). CONCLUSIONS: Heterogeneous trends were found in suicide and homicide rates within specific rural-urban, age, and gender subgroups. Prevention efforts should proactively target those subgroups identified herein as most at-risk of violence.

Exploring the complexity of firearm homicides in Harris County, Texas, from 2009 to 2021: Implications for theory and prevention.

Firearm violence is a major health problem in the United States that clusters asymmetrically across geographic and demographic lines, and the persistence and unequal distribution of firearm violence suggests that novel causal explanations and theoretical frameworks may be warranted to guide preventive strategies. Thus, this study explores the following three hypotheses that are grounded in complex systems theory: 1) trends in firearm homicides risks have shifted heterogeneously in Harris County across endemic degree of risk; 2) firearm homicides clusters have remained resilient in Harris County across the study time period; and 3), the associations between known contextual correlates of firearm homicides and the distribution of firearm homicides risks in Harris County have manifested as nonlinear. Using a retrospective study design (n = 4,397) from January 1, 2009-June 31, 2021, medicolegal death investigation data from the Harris County Institute of Forensic Sciences and estimates of community characteristics from the American Community Survey were analyzed using Joinpoint trend analysis, kernel density geospatial analysis, and proportion tests. Trend analyses revealed that firearm homicides risks shifted heterogeneously across endemic degree of risk, with geographical areas with lower initial firearm homicides risks experiencing more profound upward shifts across the time period of the study. Geospatial analyses identified the resiliency of firearm homicides clusters across the study period, particularly in central, southern, and south-western districts of the city. Finally, the relationships between known contextual correlates and the distribution of firearm homicides risks in Harris County appeared to be nonlinear, particularly regarding ethnicity. This study provides data-driven results that suggest the plausibility of complex systems theory in advancing the understanding of causality in firearm homicides. Further, these findings support the urgent need for complex systems-informed preventive efforts that account for spatiotemporal heterogeneity, key interactions that generate nonlinearity, and latent feedback loops that underlie resiliency in firearm homicides.

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.

Trauma-Informed Approaches to Medicolegal Death Investigation: A Forensic Nursing Perspective.

ABSTRACT: Forensic nurses engaged in medicolegal death investigations experience trauma-induced responses in responding to, investigating, and documenting sudden unexpected deaths. The trauma of these repeated experiences often results in diminished performance, job dissatisfaction, and burnout. The principles of trauma-informed care are not new but have not been incorporated into death investigation practices. When coupled with medicolegal death investigation procedures, application of these principles can help to alleviate distress for forensic nurses, colleagues, and decedents of concerned families. This case series illustrates how the principles of trauma-informed care can be implemented to enhance communication, deescalate emotional or threatening situations, and prevent retraumatization in the context of medicolegal death investigations.

Barriers to consistent and reliable investigation of sudden unexpected infant death: Perspectives from law enforcement.

Despite persistent efforts to advance infant death investigation, most sudden unexpected infant deaths (SUIDs) remain unexplained. Law enforcement officials contribute to SUID investigations throughout the United States, but their impacts on these investigations have not been adequately examined. In this exploratory study, 26 law enforcement officials were interviewed about their experiences and perspectives with SUID investigations. Thematic analysis of qualitative data revealed three specific difficulties law enforcement encounter during SUID investigations: (1) inadequate preparation; (2) overwhelming emotions; and (3) a victim-suspect dilemma. Findings indicate that these barriers may inhibit consistent and reliable investigation of infant death and, therefore, may impede the cause and manner of death determinations. Participants' narratives also offered insights into potential solutions, including expanded SUID training for law enforcement and use of checklists, such as the Sudden Unexpected Infant Death Investigation Reporting Form. The impacts of overwhelming emotions confronted during SUID investigation warrant further study. The victim-suspect dilemma stems from the inability of law enforcement to conclusively eliminate the possibility of homicide. This dilemma may be resolved through a clear distinction between interactions with potential evidence and interactions with the family. Law enforcement must be trained to treat all SUID families in a compassionate and non-accusatory manner, while investigating all SUID with careful attention to detail that is essential in any potential homicide investigation. A consistent, meticulous, and compassionate approach to SUID investigations will improve the reliability of information obtained and offer the best opportunity for providing answers to grieving parents.

Medicolegal death investigator workplace safety hazards: A scoping review of the literature.

In the United States, medicolegal death investigation practices and policies pertaining to sudden unexpected deaths are mandated by state government. Practices vary across states, which contributes to inconsistency in job prerequisites and training. In preparation for a study focused on occupational safety and health of medicolegal death investigators in their on-scene and follow-up activities, a scoping review was conducted to document known occupational safety risks and health-related conditions associated with death investigation. Searches used Boolean and subject heading operators both broad and narrow in scope, and search terms included scene responder, hazard, investigator, forensic pathology, injury, and safety. Twenty-five articles met inclusion criteria, which included seventeen survey-mixed method designs, two systematic reviews, five quasi-experimental designs, and one case study. Twelve articles addressed mental health and eleven focused on risks associated with infectious disease. One article addressed the risk of chemical exposure from cyanide among autopsy personnel (including forensic pathologists) and nine included a wide range of employees within the setting of medical examiner or coroner offices. One article, addressing burnout, included employees in a forensic science laboratory setting as well as medicolegal death investigators and two articles included forensic pathologists and medicolegal death investigators. Only one article addressed medicolegal death investigators specifically. Articles addressing occupational and environmental hazards of medicolegal death investigators associated with musculoskeletal, respiratory, cardiovascular, radiological, nuclear, electrical, or explosive threats were not identified. There is little published about safety risks inherent in conducting death investigations. Research is needed to adequately inform health promotion and injury prevention strategies.

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.

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.

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.

Nursing Care for Extracorporeal Membrane Oxygenation in the Trauma Patient.

Trauma patients that survive the immediate threat of death are at risk for potentially life-threatening complications such as acute respiratory distress syndrome and multisystem organ failure. Extracorporeal membrane oxygenation (ECMO) use in trauma patients has largely been controversial for concerns of inducing major hemorrhage with the use of systemic anticoagulation to prevent thrombus development while connected to the ECMO circuit. There is limited data available for specific guidelines for optimal management of the trauma population; however, recent studies suggest comparable outcomes to those of nontrauma patients treated with ECMO. The purpose of this case study was to introduce indications for implementation of ECMO in the trauma patient for pulmonary and hemodynamic compromise, describe the procedure of ECMO insertion, and delineate clinical expectations of the intensive care unit nurse within the multidisciplinary ECMO team. This case study presents a 28-year-old man who sustained a gunshot wound of the chest and was ultimately treated with ECMO for pulmonary compromise due to acute respiratory distress syndrome.

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.

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.

Nurses and Medicolegal Death Investigation.

Forensic nurses currently serve in medicolegal death investigation settings nationwide, yet registered nurses seldom recognize death investigation as a career option. The purpose of this article is to describe medicolegal death investigation in the United States and the roles nurses can achieve, depending upon state and agency job requirements. Duties and qualifications for job positions, whether filled by election, appointment, or staff hiring, are described to provide examples of nurses' roles within the medicolegal death investigation setting and to present career options. Forensic nurses have the educational preparation, medical skills, and forensic knowledge to serve within death investigation systems as a chief officer (e.g., coroner), deputy officer, or staff investigator.
