An introduction to bayesian spatial smoothing methods for disease mapping: modeling county firearm suicide mortality rates.

This article introduces bayesian spatial smoothing models for disease mapping-a specific application of small area estimation where the full universe of data is known-to a wider audience of public health professionals using firearm suicide as a motivating example. Besag, York, and Mollié (BYM) Poisson spatial and space-time smoothing models were fitted to firearm suicide counts for the years 2014-2018. County raw death rates in 2018 ranged from 0 to 24.81 deaths per 10 000 people. However, the highest mortality rate was highly unstable, based on only 2 deaths in a population of approximately 800, and 80.5% of contiguous US counties experienced fewer than 10 firearm suicide deaths and were thus suppressed. Spatially smoothed county firearm suicide mortality estimates ranged from 0.06 to 4.05 deaths per 10 000 people and could be reported for all counties. The space-time smoothing model produced similar estimates with narrower credible intervals as it allowed counties to gain precision from adjacent neighbors and their own counts in adjacent years. bayesian spatial smoothing methods are a useful tool for evaluating spatial health disparities in small geographies where small numbers can result in highly variable rate estimates, and new estimation techniques in R software have made fitting these models more accessible to researchers.

EXPOSURE TO AMBIENT HEAT AND RISK OF SPONTANEOUS ABORTION: A CASE-CROSSOVER STUDY.

BACKGROUND: Few epidemiologic studies have examined the association of ambient heat with spontaneous abortion, a common and devastating pregnancy outcome. METHODS: We conducted a case-crossover study nested within Pregnancy Study Online, a preconception cohort study (2013-2022). We included all participants reporting spontaneous abortion (n=1,524). We defined the case window as the 7 days preceding the event and used time-stratified referent selection to select control windows matched on calendar month and day of week. Within each 7-day case and control window, we measured mean, maximum, and minimum of daily maximum outdoor air temperatures. We fit splines to examine non-linear relationships across the entire year and conditional logistic regression to estimate odds ratios (OR) and 95% CI of spontaneous abortion with increases in temperature during the warm season (May-September) and decreases during the cool season (November-March). RESULTS: We found evidence of a U-shaped association between outdoor air temperature and spontaneous abortion risk based on year-round data. When restricting to warm season events (n=657), the OR for a 10-percentile increase in the mean of lag 0-6 daily maximum temperatures was 1.1 (95% CI: 0.96, 1.2) and, for the maximum, 1.1 (95% CI: 0.99, 1.2). The OR associated with any extreme heat days (>95th county-specific percentile) in the preceding week was 1.2 (95% CI: 0.95, 1.5). Among cool season events (n=615), there was no appreciable association between lower temperatures and spontaneous abortion risk. CONCLUSION: Our study provides evidence of an association between high outdoor temperatures and incidence of spontaneous abortion.

Generalizability of heat-related health risk associations observed in a large healthcare claims database of patients with commercial health insurance.

BACKGROUND: Extreme ambient heat is unambiguously associated with higher risk of illness and death. The Optum Labs Data Warehouse (OLDW), a database of medical claims from US-based patients with commercial or Medicare Advantage health insurance, has been used to quantify heat-related health impacts. Whether results for the insured sub-population are generalizable to the broader population has to our knowledge not been documented. We sought to address this question, for the US population in California from 2012 to 2019. METHODS: We examined changes in daily rates of emergency department (ED) encounters and in-patient hospitalization encounters for all-causes, heat-related outcomes, renal disease, mental/behavioral disorders, cardiovascular disease, and respiratory disease. OLDW was the source for health data for insured individuals in California, and health data for the broader population were gathered from the California Department of Health Care Access and Information (HCAI). We defined extreme heat exposure as any day in a group of 2 or more days with maximum temperatures exceeding the county-specific 97.5 th percentile and used a space-time-stratified case-crossover design to assess and compare the impacts of heat on health. RESULTS: Average incidence rates of medical encounters differed by dataset. However, rate ratios for ED encounters were similar across datasets for all causes (ratio of incidence rate ratios (rIRR) = 0.989; 95% confidence interval (CI) = 0.973, 1.011), heat-related causes (rIRR = 1.080; 95% CI = 0.999, 1.168), renal disease (rIRR = 0.963; 95% CI = 0.718, 1.292), and mental health disorders (rIRR = 1.098; 95% CI = 1.004, 1.201). Rate ratios for inpatient encounters were also similar. CONCLUSIONS: This work presents evidence that OLDW can continue to be a resource for estimating the health impacts of extreme heat.

Community-Academic Partnership to Assess the Role of Physical Disinvestment on Firearm Violence in Toledo, OH.

Reversing physical disinvestment, e.g., by remediating abandoned buildings and vacant lots, is an evidence-based strategy to reduce urban firearm violence. However, adoption of this strategy has been inconsistent across US cities. Our community-academic partnership sought to support adoption in Toledo, OH, USA, by generating locally relevant analyses on physical disinvestment and firearm violence. We used a spatial case-control design with matching. Physical disinvestment measures were derived from a citywide parcel foot audit conducted by the Lucas County Land Bank in summer 2021. Firearm violence outcomes were incident-level shootings data from the Toledo Police Department from October 2021 through February 2023. Shooting locations were matched to controls 1:4 on poverty rate, roadway characteristics, and zoning type. Exposures were calculated by aggregating parcels within 5-min walking buffers of each case and control point. We tested multiple disinvestment measures, including a composite index. Models were logistic regressions that adjusted for the matching variables and for potential spatial autocorrelation. Our sample included N = 281 shooting locations and N = 1124 matched controls. A 1-unit increase in the disinvestment score, equal to approximately 1 additional disrepair condition for the average parcel within the walking buffer, was associated with 1.68 times (95% CI: 1.36, 2.07) higher odds of shooting incidence. Across all other measures, greater disinvestment was associated with higher odds of shooting incidence. Our finding of a strong association between physical disinvestment and firearm violence in Toledo can inform local action. Community-academic partnership could help increase adoption of violence prevention strategies focused on reversing physical disinvestment.

Strategies for recruiting adolescents in rural areas in firearm injury research.

BACKGROUND: Participant recruitment is a central aspect of human sciences research. Barriers to participant recruitment can be categorised into participant, recruiter and institutional factors. Firearm injury research poses unique barriers to recruitment. This is especially true for rural adolescents, who are at high risk for firearm-related injury and death, and whose voice is often absent in firearms research. In particular, recruitment strategies targeting adolescents should align with developmental changes occurring during this life stage. Identifying strategies to address recruitment barriers tailored to firearm-related research can help future researchers engage rural adolescents in injury prevention efforts. PURPOSE: The purpose of the current methodology paper is to outline barriers and provide strategies for recruiting rural adolescents in firearms research informed by the Youth Experiences in Rural Washington: Research on Firearm Safety project, a mixed-methods, community-based participatory research study of 13-18 year-olds residing in rural Washington. STRATEGIES: Recruitment barriers and related strategies were organised by participant-related and recruiter-related/institutional-related factors. While carrying out the study, key considerations or strategies which addressed multiple participant and recruiter/institutional factors, emerged with potential to enhance firearm-related research with rural adolescents more broadly. Key considerations included logistics (ie, scheduling flexibility, adequate and aligned incentives), use of a community-based participatory research approach and accounting for developmental stage. CONCLUSION: Reducing the burden of firearm injury and death for rural adolescents and developing effective interventions requires understanding and navigating recruitment barriers. Strategies used in the current project can guide future qualitative or mixed methods data collection informing firearm injury prevention.

Racial and ethnic differences in the association between depressive symptoms and cognitive outcomes in older adults: Findings from KHANDLE and STAR.

INTRODUCTION: Depressive symptoms are associated with higher risk of dementia, but how they impact cognition in diverse populations is unclear. METHODS: Asian, Black, Latino, or White participants (n = 2227) in the Kaiser Healthy Aging and Diverse Life Experiences (age 65+) and the Study of Healthy Aging in African Americans (age 50+) underwent up to three waves of cognitive assessments over 4 years. Multilevel models stratified by race/ethnicity were used to examine whether depressive symptoms were associated with cognition or cognitive decline and whether associations differed by race/ethnicity. RESULTS: Higher depressive symptoms were associated with lower baseline verbal episodic memory scores (-0.06, 95% CI: -0.12, -0.01; -0.15, 95% CI: -0.25, -0.04), and faster decline annually in semantic memory (-0.04, 95% CI: -0.07, -0.01; -0.10, 95% CI: -0.15, -0.05) for Black and Latino participants. Depressive symptoms were associated with lower baseline but not decline in executive function. DISCUSSION: Depressive symptoms were associated with worse cognitive outcomes, with some evidence of heterogeneity across racial/ethnic groups. HIGHLIGHTS: We examined whether baseline depressive symptoms were differentially associated with domain-specific cognition or cognitive decline by race/ethnicity. Depressive symptoms were associated with worse cognitive scores for all racial/ethnic groups across different domains examined. Higher depressive symptoms were associated with faster cognitive decline for semantic memory for Black and Latino participants. The results suggest a particularly harmful association between depressive symptoms and cognition in certain racial/ethnic groups.

Bullying and physical violence and their association with handgun carrying among youth growing up in rural areas.

OBJECTIVES: This study builds on prior research showing a strong relationship between handgun carrying and delinquent behaviors among urban youth by examining the association between handgun carrying trajectories and various types of violence in a rural sample. METHODS: This study uses data from a longitudinal cohort study of 2002 public school students in the United States from 12 rural communities across 7 states from ages 12-26 (2005-2019). We used logistic regressions to assess associations of various bullying and physical violence behaviors with latent trajectories of handgun carrying from adolescence through young adulthood. RESULTS: Compared to youth with very low probabilities of carrying a handgun in adolescence and young adulthood, trajectories with high probabilities of handgun carrying during adolescence or young adulthood were associated with greater odds of using bullying (odds ratios (ORs) ranging from 1.9 to 11.2) and higher odds of using physical violence during adolescence (ORs ranging from 1.5 to 15.9) and young adulthood (ORs ranging from 1.9 to 4.7). These trajectories with higher probabilities of handgun carrying were also associated with greater odds of experiencing physical violence like parental physical abuse and intimate partner violence, but not bullying. CONCLUSION AND IMPLICATION: Experiencing and using bullying and physical violence were associated with specific patterns of handgun carrying among youth growing up in rural areas. Handgun carrying could be an important focus of violence prevention programs among those youth.

Computed tomography-based volume calculations of renal ischemia predicts post-traumatic renal function after renal infarction injury.

OBJECTIVES: To describe a systematic method to quantify the severity of renal infarction injury and assess its association with post-traumatic renal function after blunt trauma. METHODS: We retrospectively reviewed all patients who suffered an AAST grade IV renal infarction injury without active bleeding secondary to blunt trauma between 1/2010 and 10/2020. Only patients with a pre-traumatic eGFR within 12 months of injury and post-traumatic eGFR within 3-12 months were included. Percentage of renal ischemia was defined as: (ischemic volume/total volume) × 100%. Two radiologists reviewed computed tomography images to determine ischemic and overall cross-sectional areas using the polygon region of interest tool. These areas were multiplied by slice thickness to obtain ischemic and total volumes. Intraclass correlation coefficient was used to assess consistency between radiologists. Linear regression analyses were used to assess the association between percentage of renal ischemia and post-traumatic renal function. RESULTS: Thirty-five of 140 (25.0%) patients met inclusion criteria. The median (IQR) pre-trauma eGFR was 107.7 ml/min/1.73m2 (90.6-121.8), percentage of renal ischemia was 8.4% (2.9-30.1), and decrease in eGFR after trauma was 12.9 ml/min/1.73m2 (0.4-32.6). There was excellent reliability in calculating ischemic volume (ICC = 0.987) and total kidney volume (ICC = 0.995) between two radiologists. When adjusting for pre-traumatic eGFR, patient age, and injury severity score, a 10% increase in ischemic volume was associated with a post-injury eGFR value that was 8.0 ml/min/1.73 m2 (95% CI - 11.2, - 4.7) lower. CONCLUSIONS: CT-based volume calculation of renal ischemia may be utilized to quantify kidney injury and be associated with post-traumatic renal function loss.

Neighborhood segregation, tree cover and firearm violence in 6 U.S. cities, 2015-2020.

Neighborhood segregation by race and income is a structural determinant of firearm violence. Addressing green space deficits in segregated neighborhoods is a promising prevention strategy. This study assessed the potential for reducing firearm violence disparities by increasing access to tree cover. Units of analysis were census tracts in six U.S. cities (Baltimore, MD; Philadelphia, PA; Richmond, VA; Syracuse, NY; Washington, DC; Wilmington, DE). We measured segregation using the index of concentration at the extremes (ICE) for race-income. We calculated proportion tree cover based on 2013-2014 imagery. Outcomes were 2015-2020 fatal and non-fatal shootings from the Gun Violence Archive. We modeled firearm violence as a function of ICE, tree cover, and covariates representing the social and built environment. Next, we simulated possible effects of "tree equity" programs, i.e., raising tract-level tree cover to a specified baseline level. In our fully-adjusted model, higher privilege on the ICE measure (1 standard deviation, SD) was associated with a 42% reduction in shootings (incidence rate ratio (IRR) = 0.58, 95% CI [0.54 0.62], p < 0.001). A 1-SD increase in tree cover was associated with a 9% reduction (IRR = 0.91, 95% CI [0.86, 0.97], p < 0.01). Simulated achievement of 40% baseline tree cover was associated with reductions in firearm violence, with the largest reductions in highly-deprived neighborhoods. Advancing tree equity would not disrupt the fundamental causes of racial disparities in firearm violence exposure, but may have the potential to help mitigate those disparities.

Assessment of county-level proxy variables for household firearm ownership.

Our objective in this study was to evaluate how well proxy variables for firearm ownership used in county-level studies measure firearm ownership. We applied Bayesian spatial smoothing methods to calculate county-level estimates of household firearm ownership using Behavioral Risk Factor Surveillance System (BRFSS) data (2013-2018). We compared these estimates to four proxies for county-level firearm ownership: the proportion of suicides that were firearm suicides, the average of the proportion of suicides that were firearm suicides and the proportion of homicides that were firearm homicides, gun shops per capita, and federal firearm licenses per capita. U.S. counties for which BRFSS data on household firearm ownership were collected and available for release (n = 304) were included. The median (interquartile range) prevalence of household firearm ownership was 46.6% (37.2%, 56.4%). The per capita rate of federal firearm licenses was most strongly correlated with household firearm ownership (r = 0.70; 95% CI: 0.63, 0.75) followed by the proportion of suicides that were firearm suicides (r = 0.45; 95% CI: 0.36, 0.54). These correlations were stronger among counties with populations of ≥250,000 people. The per capita rate of federal firearm licenses was the best proxy variable for firearm ownership at the county level, however, a better proxy should be identified.

Extreme Risk Protection Orders in Washington : A Statewide Descriptive Study.

BACKGROUND: In the United States, 74% of homicides and 51% of suicides involve firearms. Using extreme risk protection order (ERPO) laws, petitioners can request restricting firearm access for individuals (known as "respondents") who pose a risk to themselves or others. OBJECTIVE: To characterize respondents and circumstances of ERPOs. DESIGN: Descriptive study. SETTING: State of Washington. PARTICIPANTS: All ERPO respondents during 8 December 2016 to 10 May 2019. MEASUREMENTS: Reason for filing the ERPO; characteristics of respondents; respondent's reported history of domestic violence perpetration, mental illness, substance misuse, and suicide ideation or attempt; number and type of firearms removed; and ERPO petition outcome (granted or not granted). RESULTS: The ERPOs were filed for concerns about harm to self (n = 67), harm to others (n = 86), or harm to both self and others (n = 84). Of all ERPOs, 87% were filed by law enforcement and 81% were granted. At least 1 firearm was removed from 64% of respondents, with a total of 641 firearms removed. The petitioner reported prior domestic violence perpetration by the respondent in 24% of cases, and a prior diagnosis of a mental health condition and substance misuse for the respondent in 40% and 47% of cases, respectively. Of all respondents, 62% had a history of suicidal ideation or attempt according to the petitioner. As part of the ERPO process, the court ordered mental health evaluation in 30% of cases. LIMITATION: Filing of the forms was inconsistent. CONCLUSION: Laws regarding ERPOs are a potential tool to help protect patients or family members from harming themselves or others by restricting firearm possession and purchase. Further studies are needed to determine the long-term effects of these laws and identify approaches to increase their use. PRIMARY FUNDING SOURCE: State of Washington.

The association of alcohol use and heavy drinking with subsequent handgun carrying among youth from rural areas.

PURPOSE: Alcohol use and handgun carrying are more prevalent among youth in rural than urban areas and their association may be stronger among rural adolescents. Alcohol use may be modifiable with implications for reducing handgun carrying and firearm-related harm. We examined the association between lagged alcohol use and subsequent handgun carrying in rural areas and examined variation in the association by developmental stages, hypothesizing that it would be stronger among adolescents than youth adults. METHODS: We used a longitudinal sample of 2,002 adolescents from ages 12 to 26 growing up in 12 rural communities in 7 states with surveys collected from 2004 to 2019. We estimated the association of lagged past-month alcohol use on handgun carrying in the subsequent 12 months using population-average generalized estimating equations with logistic regression on multiply imputed data. FINDINGS: During adolescence (ages 12-18), those who drank heavily had 1.43 times the odds (95% CI = [1.01, 2.03]) of subsequent handgun carrying compared to those who did not drink alcohol, and those who consumed alcohol but did not drink heavily had 1.30 times the odds of subsequent handgun carrying compared to those who did not drink (95% CI = [0.98, 1.71]). During young adulthood (ages 19-26), associations of alcohol use (OR = 1.28; 95% CI = [0.94, 1.63]) and heavy drinking (OR = 1.38; 95% CI = [1.08, 1.68]) were similar to adolescence. CONCLUSIONS: Alcohol use and subsequent handgun carrying were positively associated during adolescence and young adulthood among individuals who grew up in rural areas, similar to findings in urban areas. Reducing alcohol use may be an important strategy to prevent handgun carrying and firearm-related harm among young people in rural areas.

Warm season ambient ozone and children's health in the USA.

BACKGROUND: Over 120 million people in the USA live in areas with unsafe ozone (O3) levels. Studies among adults have linked exposure to worse lung function and higher risk of asthma and chronic obstructive pulmonary disease (COPD). However, few studies have examined the effects of O3 in children, and existing studies are limited in terms of their geographic scope or outcomes considered. METHODS: We leveraged a dataset of encounters at 42 US children's hospitals from 2004-2015. We used a one-stage case-crossover design to quantify the association between daily maximum 8-hour O3 in the county in which the hospital is located and risk of emergency department (ED) visits for any cause and for respiratory disorders, asthma, respiratory infections, allergies and ear disorders. RESULTS: Approximately 28 million visits were available during this period. Per 10 ppb increase, warm-season (May through September) O3 levels over the past three days were associated with higher risk of ED visits for all causes (risk ratio [RR]: 0.3% [95% confidence interval (CI): 0.2%, 0.4%]), allergies (4.1% [2.5%, 5.7%]), ear disorders (0.8% [0.3%, 1.3%]) and asthma (1.3% [0.8%, 1.9%]). When restricting to levels below the current regulatory standard (70 ppb), O3 was still associated with risk of ED visits for all-cause, allergies, ear disorders and asthma. Stratified analyses suggest that the risk of O3-related all-cause ED visits may be higher in older children. CONCLUSIONS: Results from this national study extend prior research on the impacts of daily O3 on children's health and reinforce the presence of important adverse health impacts even at levels below the current regulatory standard in the USA.

Preparing for a burn disaster in Brazil: Geospatial modelling to inform a coordinated response.

INTRODUCTION: To optimize the early care of burned patients, protocols were developed that guide pre-hospital care and the need to transfer to a specialized burn treatment unit. Burn disasters are an important public health concern in developed and developing nations. Among the early steps in disaster preparedness is the understanding of geographic locations and capacity of burn care facilities. We aimed to map and classify medical facilities that provide burn care in Brazil and to undertake a location-allocation analysis to identify which could be targeted to increase capacity. METHODS: A review of burn hospitalizations was conducted using Brazilian Ministry of Health data. Capacity was defined by number of burn patients admitted each year and bed type. Spatial population data per one-square kilometer were obtained from World Pop as a raster dataset. A road network dataset using Open Street Map data was created to conduct the drive time analysis. Location/allocation analysis was conducted to identify the proportion of Brazil's population living within 2- and 6-hours' drive time of a burn care capable hospital, stratified by the level of hospital capacity. Hospitals were ranked according to number of additional people served. RESULTS: We found 26.471 burn admissions. Of these, 3.508(13,2 %) were ICU admissions. A total of 735(2,7 %) hospital deaths occurred under the selected burn codes. In all, 1.273 facilities admitted burn patients, and 263(20,7 %) reported ICU admissions of burn patients. Seventeen hospitals were classified as maximum capacity facilities. Additional 23 hospitals were identified as potential targets for capacity building. Most maximum capacity hospitals are clustered in the Southeast of Brazil. Currently, 40.8 % of the Brazilian population live within 2 h of a maximum capacity facility. A large part of the population lives farther than 6 h away from a maximum capacity hospital. Most of the potential targets for capacity building are located near the coast of Brazil. DISCUSSION: We mapped and classified facilities that provide public burn care in Brazil. We identified public facilities that could be targeted to increase capacity to improve access for patients in the event of a burn disaster. Mapping, planning, and coordinating response is key for optimal outcomes in Mass Casualties Incidents. Cataloging and understanding local resources is a crucial first step in disaster management. Inequality in profiles can determine specific regional needs. Specialized burn centers are rare in regions other than the southeast. Health equity should be considered when planning disaster preparedness initiatives. Location-allocation modelling may assist in universal and equitable burn care service offerings. CONCLUSION: This study proposes an initial step in the classification and mapping of available burn treatment centers and population coverage in Brazil.

Rural-Urban Variation in the Association of Adolescent Violence and Handgun Carrying in the United States, 2002-2019.

Importance: Adolescent handgun carrying is associated with increased risk of firearm-related violence. Most evidence on adolescent handgun carrying is from urban areas, but these findings may not generalize to rural areas. Objective: To examine differences in associations of adolescent interpersonal violence with handgun carrying across the rural-urban continuum. Design, Setting, and Participants: This cross-sectional study used nationally representative data from the US National Survey on Drug Use and Health among adolescents aged 12 to 17 years from 2002 to 2019 to estimate time-varying prevalence ratios (PRs) and prevalence differences (PDs) between interpersonal violence and handgun carrying across the rural-urban continuum. Analyses were conducted in April to July 2022. Exposures: Any past-year serious fighting, group fighting, and attacking with intent to harm. Main Outcomes and Measures: Any past-year handgun carrying. Associations were estimated within county rural-urban strata using the US Department of Agriculture's Rural-Urban Continuum Codes. Results: In each year, the sample included a weighted count of almost 25 million adolescents, with 50.9% (95% CI, 50.2%-51.6%) males and 24.7% (95% CI, 23.8%-25.6%) Hispanic adolescents, 13.5% (95% CI, 12.8%-14.2%) non-Hispanic Black adolescents, and 51.8% (95% CI, 50.8%-52.8%) non-Hispanic White adolescents in 2019. More rural counties had less racial and ethnic diversity. For example, 81.1% (95% CI, 75.9%-85.4%) of adolescents were non-Hispanic White in the most rural counties vs 43.1% (95% CI, 41.7%-44.6%) of adolescents were non-Hispanic White in the most urban counties in 2019. Adolescent handgun carrying increased over time, with the largest increases in the most rural counties, where the prevalence of adolescent handgun carrying increased from 5.2% (95% CI, 3.8%-7.0%) in 2003 to 12.4% (95% CI, 8.9%-16.9%) in 2019. PRs for the association of violence and handgun carrying were greater in more urban counties. For example, in the most urban counties in 2019, adolescents involved in a group fight had 3.7 (95% CI, 2.9-4.8) times the prevalence of handgun carrying vs those not involved in a group fight; this PR was 3.1 (95% CI, 1.6-5.6) in the most rural counties. PDs were similar and, in some cases, larger in rural areas. For example, in the most urban counties in 2019, handgun carrying prevalence was 7.5% (95% CI, 5.7%-9.5%) higher among adolescents who were involved in a group fight compared with those who were not; this PD was 21.8% (95% CI, 8.2%-37.8%) in the most rural counties, where handgun carrying was more common. Conclusions and Relevance: This cross-sectional study found that associations of interpersonal violence with handgun carrying were stronger in relative terms in urban areas than in rural areas; however, a higher percentage of rural than urban adolescents carried handguns, resulting in a greater absolute prevalence of handgun carrying associated with violence in rural areas than in urban areas. These findings suggest opportunities for preventing handgun carrying-related harms may differ between rural and urban communities.

Social Workers' Perspectives on Extreme Risk Protection Orders.

Extreme risk protection orders (ERPOs), which allow for the temporary restriction of firearm access for individuals at substantial risk of harming themselves and/or others, are a promising policy tool to address increasing rates of firearm-related suicide, homicide, and mass shootings. Social workers frequently assess clients at risk of firearm-related harm, positioning social workers to play a key role in ERPO implementation. This study sought to understand social workers' perspectives on ERPOs. Authors invited 6,910 licensed social workers in Washington state to participate in a survey in May and June of 2021 about facilitators and barriers to their willingness to counsel clients' family members, contact law enforcement, or independently file ERPOs for clients at risk of harm to self (HTS) or others (HTO). Of the 1,381 survey participants, most were willing to counsel (96 percent for HTS; 96 percent HTO), contact law enforcement (84 percent for HTS; 87 percent for HTO), or independently file an ERPO (78 percent for HTS; 79 percent for HTO). Common barriers associated with willingness were lack of understanding about the ERPO process and concerns with involving the legal system/law enforcement. Key facilitators included training social workers about ERPOs and availability of legal experts for consultations. Social workers are willing to incorporate ERPOs into their practice for clients, but remaining barriers need to be addressed to support the practice.

Impact of community-level socioeconomic disparities on quality of life after burn injury: A Burn Model Systems Database study.

INTRODUCTION: Individual-level socioeconomic disparities impact burn-related incidence, severity and outcomes. However, the impact of community-level socioeconomic disparities on recovery after burn injury is poorly understood. As a result, we are not yet able to develop individual- and community-specific strategies to optimize recovery. Therefore, we aimed to characterize the association between community-level socioeconomic disparities and long-term, health-related quality of life after burn injury. METHODS: We queried the Burn Model System National Longitudinal Database for participants who were> 14 years with a zip code and who had completed a health-related quality of life (HRQOL) questionnaire (VR-12) 6 months after injury. BMS data were deterministically linked by zip code to the Distressed Communities Index (DCI), which combines seven census-derived metrics into a single indicator of economic well-being, education, housing and opportunity at the zip code level. Hierarchical linear models were used to estimate the association between community deprivation and HRQOL 6 months after burn injury, as measured by mental (MCS) and physical (PCS) component summary scores of the SF12/VR12. RESULTS: 342 participants met inclusion criteria. Participants were mostly male (n = 239, 69 %) and had a median age of 48 years (IQR 33-57 years). Median %TBSA was 10 (IQR 3-28). More than one-third of participants (n = 117, 34 %) lived in a community within the highest two distress quintiles. After adjusting for age, race/ethnicity, number of trips to the operating room (OR) and pre-injury PCS, neighbourhood distress was negatively associated with 6-month PCS (ß-0.05, 95 % CI [-0.09,-0.01]). Increasing age and lower pre-injury PCS were also negatively associated with 6-month PCS. There was no observed association between neighbourhood distress and 6-month MCS after adjustment for age, participant race/ethnicity, number of trips to the OR and pre-injury MCS. Higher pre-injury MCS was associated with 6-month MCS (ß0.54, 95 % CI [-0.41,0.67]). CONCLUSIONS: Community distress is associated with lower PCS at 6 months after burn injury but no association with MCS was identified. Pre-injury HRQOL is associated with both PCS and MCS after injury. Further study of the factors underlying the relationship between community distress and physical functional recovery (e.g., access to rehabilitation services, availability of adaptations) is required to identify potential interventions.

Electroacupuncture for Pain Outcomes in a Trauma Center's Acute Pain Service: A Retrospective Observational Study.

Background: Evidence for acupuncture to treat pain is growing. Electrostimulation of acupuncture needles (electroacupuncture) is common for pain and is thought to augment the therapeutic effect. Objectives: To examine the association of pain outcomes after a single acupuncture session with electrostimulation included (EA) compared with no electrostimulation included (NEA). Methods: A retrospective observational study was conducted using electronic health records of acupuncture sessions for adults with acute pain under the care of an acute pain service. Paired t-test and linear regression were used to report pain intensity changes after a single acupuncture session and by including EA. Ordered logistic regression was used to report categorical pain relief. Logistic regression was used to explore the odds of adding EA and the patient's age, gender, and pretreatment pain. Results: From July 24, 2017, through November 9, 2020, 465 acupuncture sessions recorded EA (n = 194), or NEA (n = 271). Acupuncture, independent of EA status, reduced pain intensity by a mean 2.5 points. EA was associated with a mean 0.38-point reduction in pain intensity more than NEA (confidence interval [95% CI]: -0.75 to -0.01). Among sessions reporting categorical pain relief (n = 415), higher relief was more likely with EA (odds ratio = 2.16, 95% CI: 1.52-3.08). There was no association between EA and the patient's age, gender, and pretreatment pain intensity. Conclusions: After a single acupuncture session, both EA and NEA reduced pain intensity. Higher categorical pain relief was reported with EA, though the clinical meaning is uncertain. Future research should focus on well-defined populations for electroacupuncture and factors for including electrostimulation.

Integration of extreme risk protection orders into the clinical workflow: Qualitative comparison of clinician perspectives.

Extreme risk protection orders (ERPO) seek to temporarily reduce access to firearms for individuals at imminent risk of harming themselves and/or others. Clinicians, including physicians, nurse practitioners, and social workers regularly assess circumstances related to patients' risk of firearm-related harm in the context of providing routine and acute clinical care. While clinicians cannot independently file ERPOs in most states, they can counsel patients or contact law enforcement about filing ERPOs. This study sought to understand clinicians' perspectives about integrating ERPO counseling and contacting law enforcement about ERPOs into their clinical workflow. We analyzed responses to open-ended questions from an online survey distributed May-July of 2021 to all licensed physicians (n = 23,051), nurse practitioners (n = 8,049), and social workers (n = 6,910) in Washington state. Of the 4,242 survey participants, 1,126 (26.5%) responded to at least one of ten open-ended questions. Two coders conducted content analysis. Clinicians identified barriers and facilitators to integrating ERPOs into the clinical workflow; these influenced their preferences on who should counsel or contact law enforcement about ERPOs. Barriers included perceptions of professional scope, knowledge gaps, institutional barriers, perceived ERPO effectiveness and constitutionality, concern for safety (clinician and patient), and potential for damaging provider-patient therapeutic relationship. Facilitators to address these barriers included trainings and resources, dedicated time for counseling and remuneration for time spent counseling, education on voluntary removal options, and ability to refer patients to another clinician. Participants who were hesitant to be the primary clinician to counsel patients or contact law enforcement about ERPOs requested the ability to refer patients to a specialist, such as social workers or a designated ERPO specialist. Results highlight the complex perspectives across clinician types regarding the integration of ERPO counseling into the clinical workflow. We highlight areas to be addressed for clinicians to engage with ERPOs.

School Handgun Carrying Among Youth Growing Up in Rural Communities.

PURPOSE: To characterize school handgun carrying and violence risk factors among rural youth. METHODS: Using a sample of rural youth (n = 1995), we quantified the proportion who carried a handgun to school, carried but not to school, and did not carry across grades 7-12 and endorsed risk factors for violence in individual, peer, school, and community domains. RESULTS: Overall, 3% (95% confidence interval [CI]: 2%-4%) of youth ever carried to school; 15% (95% CI: 14%-16%) carried but not to school; and 82% (95% CI: 80%-84%) never carried. Violence risk factors (e.g., attacking someone) were more commonly endorsed by youth who carried to school (84%; 95% CI: 73%-95%) than those who carried but not to school (51%; 95% CI: 44%-58%) and did not carry (23%; 95% CI: 20%-26%). DISCUSSION: Carrying a handgun to school in rural areas is not common; however, it is associated with risk factors for violence. Understanding violence risk factors among youth who carry handguns to school could inform violence prevention programs in rural areas.
