Safer Behind Bars? Comparing In-Custody Deaths Prior to and During Incarceration.

INTRODUCTION: This project aims to characterize trauma-associated deaths of the American incarcerated population through legal intervention (LI) or death by law enforcement officials while in custody before and during incarceration. We determined the preceding events leading to violent death, including initiation of medical care, use of restraints and force, and demographics of the victims. METHODS: We used National Violent Death Reporting System data from the years 2003-2019 to identify deaths that occurred while in custody or incarcerated, including discriminate and narrative data. Event information included weapon type, location of death, incident type, incarceration status, use of restraints, and prone positioning. RESULTS: There were 86 victims who died from LI included in the analysis. Most events occurred after incarceration. All victims in our cohort were male, and race was an associated factor for death by LI. Only 16% of victims had an education level above high school/general educational development. Death by firearm compared to other weapons was significantly more common in the in-custody but not yet incarcerated group (83% versus 42%, P ≤ 0.0001). Other associated factors included a history of mental health, physical confrontations, the belief that the victim had a weapon, and being restrained in prone positioning. CONCLUSIONS: Our study shows that racial minority victims are disproportionately affected by LI deaths. Firearms and restraint type were important factors in LI deaths. Our findings suggest that violence prevention in the justice system should focus on prevention and de-escalation across setting with specific attention to use of force and inmate access to the weapons of police, guards, and other law and justice system workers. More transparent quality data is sorely needed to adequately define and address this problem.

Sex Differences in Violent Death During Incarceration and Legal Intervention.

INTRODUCTION: This study clarifies the differences in death during incarceration and legal intervention between males and females, delineating the differences in demographic features and the circumstances of the violent death including location, injury pattern, and perpetrator. METHODS: The data used are from the National Violent Death Reporting System database from 2003 to 2019. All victims were either in custody, in the process of custody, or in prison. Sex was coded as female or male and as assigned at birth. All analyses were conducted using SAS 9.4 software using chi-square tests, with an alpha of 0.05 to test significant differences in the circumstances of mortality and demographic characteristics for each group. RESULTS: Our findings show that suicide was the most common cause of death during incarceration for both females and males (89.8% versus 77.4%; P < 0.001). Homicide was less common in females (1.6% versus 14.8%; P < 0.001) and legal intervention only occurred in males (2.2%; P < 0.001). Male victims were more likely to be of non-White race/ethnicity compared to females, while females were more likely to be experiencing homelessness, have documented mental illness, and comorbid substance abuse. CONCLUSIONS: Victim sex is significantly associated with circumstances of violent death among the incarcerated and highlights the need for appropriate mental health and substance abuse treatment.

Suicide Among Persons Experiencing Homelessness.

INTRODUCTION: This study aims to characterize suicide and associated disparities among persons experiencing homelessness (PEH). MATERIALS AND METHODS: We reviewed suicide victims in the National Violent Death Reporting System (NVDRS) from 2003 to 2018 and compared factors surrounding suicides of PEH to factors of housed victims. We also utilized the Point-in-Time (PIT) survey (2010-2018), and census population estimates, to estimate suicide rates among PEH and the wider population. RESULTS: 1.1% of suicide victims were described as experiencing homelessness at the time of their deaths, a value that is disproportional given the overall homeless rates of 0.2% in the past decade. Compared to nonhomeless victims, PEH were more likely to be younger, Black, male, and nonveterans. PEH were significantly more likely to have an identified alcohol/substance use disorder. PEH were half as likely to die via firearm and were more likely to die in natural areas, motels, and the streets. PEH were significantly more likely to have a history of suicidal thoughts, a history of suicide attempts, and a history of disclosure of intent, particularly to health care workers. CONCLUSIONS: PEH are disproportionately overrepresented among all suicide victims, but the circumstances surrounding their deaths create opportunity for targeted interventions.

Characterizing environmental asthma triggers and healthcare use patterns in Puerto Rico.

Objective: Asthma carries a high burden of disease for residents of Puerto Rico. We conducted this study to better understand asthma-related healthcare use and to examine potential asthma triggers.Methods: We characterized asthma-related healthcare use in 2013 by demographics, region, and date using outpatient, hospital, and emergency department (ED) insurance claims with a primary diagnostic ICD-9-CM code of 493.XX. We examined environmental asthma triggers, including outdoor allergens (i.e., mold and pollen), particulate pollution, and influenza-like illness. Analyses included descriptive statistics and Poisson time-series regression.Results: During 2013, there were 550,655 medical asthma claims reported to the Puerto Rico Healthcare Utilization database, representing 148 asthma claims/1,000 persons; 71% of asthma claims were outpatient visits, 19% were hospitalizations, and 10% were ED visits. Females (63%), children aged ≤9 years (77% among children), and adults aged ≥45 years (80% among adults) had the majority of asthma claims. Among health regions, Caguas had the highest asthma claim-rate at 142/1,000 persons (overall health region claim-rate = 108). Environmental exposures varied across the year and demonstrated seasonal patterns. Metro health region regression models showed positive associations between increases in mold and particulate matter <10 microns in diameter (PM10) and outpatient asthma claims.Conclusions: This study provides information about patterns of asthma-related healthcare use across Puerto Rico. Increases in mold and PM10 were associated with increases in asthma claims. Targeting educational interventions on exposure awareness and reduction techniques, especially to persons with higher asthma-related healthcare use, can support asthma control activities in public health and clinical settings.

National unintentional carbon monoxide poisoning estimates using hospitalization and emergency department data.

Unintentional non-fire-related (UNFR) carbon monoxide (CO) poisoning is a leading cause of poisoning in the US and a preventable cause of death. We generated national estimates of accidental CO poisoning and characterized the populations most at risk. UNFR CO poisoning cases were assessed using hospitalization and emergency department (ED) data from the Healthcare Costs and Utilization Project National Inpatient Sample and Nationwide Emergency Department Sample databases. We used hospitalization data from 2003 to 2013 and ED data from 2007 to 2013. We calculated trends using a linear regression of UNFR CO poisonings over the study period and age-adjusted rates using direct standardization and U.S. Census Bureau estimates. During 2003-2013, approximately 14,365 persons (4.1 cases/million annually) with confirmed or probable UNFR CO poisoning were admitted to hospitals and the annual rate of poisonings showed a weak downward trend (p = 0.12). During 2007-2013, approximately 101,847 persons (48.3 visits/million annually) visited the ED and the annual rate of poisonings showed a significant downward trend (p ≤ 0.01). Most UNFR CO hospital cases involved patients who were older (aged 45-64 years), white, male, or living in the South or Midwest. Overall, the rate of hospitalizations did not change over the study period. Unintentional CO poisoning is preventable and these cases represent the most recent national estimates. ED visits declined over the study period, but the hospitalization rates did not change. This emphasizes the need for prevention efforts, such as education in the ED setting, increased use of CO alarms, and proper use and maintenance of fuel-powered household appliances.

Left out in the cold: Homicide amongst persons experiencing homelessness.

BACKGROUND: There is no American population-level study comparing the characteristics of homicides involving victims who were vs were not experiencing homelessness at time of death. We aim to identify variables surrounding homeless homicide that are unique, and intervenable. METHODS: In this retrospective cohort study, we reviewed the National Violent Death Reporting System (NVDRS) from 2003 to 2018 and compared the characteristics surrounding homicides of victims who were not-homeless (cohort 1) vs experiencing homelessness (cohort 2) at death. We utilized the available perpetrator data to characterize the average perpetrator for each cohort. We considered housing status to be our primary predictor and recorded NVDRS variables, such as age of victims and likelihood to know perpetrators, to be our primary outcomes. RESULTS: 81,212 Homicide Victims and 60,982 Homicide Perpetrators were included in analysis. Homeless cohort victims were more likely younger, White, male, and to have a known mental health or substance abuse disorder. PEH were also more likely to have co-morbid mental health and substance abuse disorders but were roughly half as likely to be getting treatment for said disorders. Circumstances surrounding incidents, including geographic location, mechanism of injury, and premeditation, varied; homeless cohort victims were more likely to die in random acts of violence, but were less likely to die via firearm. CONCLUSIONS: There is room for targeted interventions against homeless homicides. LEVEL OF EVIDENCE: Epidemiological, Level IV.

Social vulnerability is associated with increased morbidity following colorectal surgery.

INTRODUCTION: Neighborhood measures of social vulnerability encompassing multiple sociodemographic factors can be used to quantify disparities in outcomes. We hypothesize patients with high Social Vulnerability Index (SVI) are at increased risk of morbidity following colectomy. METHODS: We used local 2012-2017 National Surgical Quality Improvement Program (NSQIP) data to study colectomy patients, examining associations between SVI and postoperative outcomes. RESULTS: We included 976 patients from five hospitals. High SVI (>75th percentile) was associated with increased postoperative morbidity on unadjusted analysis (OR 1.84, 95% CI 1.35-2.52, p < 0.001); this association persisted after adjusting for demographics and comorbidities (OR 1.63, 95% CI 1.15-2.31, p = 0.005). The association with SVI was not significant after adjusting for perioperative risk modifiers such as emergent presentation (OR 1.37, 95% CI 0.95-1.98, p = 0.10). CONCLUSIONS: High social vulnerability is associated with increased postoperative complications. This effect appears mediated by perioperative risk factors, suggesting potential to improve outcomes by facilitating timely surgical intervention.

First known trace fossil of a nesting iguana (Pleistocene), The Bahamas.

Most species of modern iguanas (Iguania, Iguanidae) dig burrows for dwelling and nesting, yet neither type of burrow has been interpreted as trace fossils in the geologic record. Here we describe and diagnose the first known fossil example of an iguana nesting burrow, preserved in the Grotto Beach Formation (Early Late Pleistocene, ~115 kya) on San Salvador Island, The Bahamas. The trace fossil, located directly below a protosol, is exposed in a vertical section of a cross-bedded oolitic eolianite. Abundant root traces, a probable land-crab burrow, and lack of ghost-crab burrows further indicate a vegetated inland dune as the paleoenvironmental setting. The trace fossil matches dimensions and overall forms of burrows made by modern iguanas, and internal structures indicate active backfilling consistent with modern iguana nesting burrows. The trace fossil is also located on an island with a modern native species of rock iguana (Cyclura riyeli riyeli), suggesting a presence of iguanas on San Salvador since the Late Pleistocene. This nesting burrow may provide a search image for more fossil iguana burrows in The Bahamas and other places with long-established iguana species and favorable geological conditions for preserving their burrows.
