United States trends in healthcare charges for pediatric firearm injuries.

BACKGROUND: From 2009 to 2016, >21,000 children died and an estimated 118,000 suffered non-fatal injuries from firearms in the United States. Limited data is available on resource utilization by injury intent. We use hospital charges as a proxy for resource use and sought to: 1) estimate mean charges for initial ED and inpatient care for acute firearm injuries among children in the U.S.; 2) compare differences in charges by firearm injury intent among children; and 3) evaluate trends in charges for pediatric firearm injuries over time, including within intent subgroups. METHODS: In this repeated cross-sectional analysis of the 2009-2016 Nationwide Emergency Department Sample, we identified firearm injury cases among children aged ≤19 years using ICD-9-CM and ICD-10-CM external cause of injury codes (e-codes). Injury intent was categorized using e-codes as unintentional, assault-related, self-inflicted, or undetermined. Linear regressions utilizing survey weighting were used to examine associations between injury intent and healthcare charges, and to evaluate trends in mean charges over time. RESULTS: Among 21,951 unweighted cases representing 102,072 pediatric firearm-related injuries, mean age was 16.6 years, and a majority were male (88.2%) and publicly insured (51.5%). Injuries were 53.9% assault-related, 37.7% unintentional, 1.8% self-inflicted, and 6.7% undetermined. Self-inflicted injuries had higher mean charges ($98,988) than assault-related ($52,496) and unintentional ($28,618) injuries (p < 0.001). Self-inflicted injuries remained associated with higher mean charges relative to unintentional injuries, after adjusting for patient demographics, hospital characteristics, and injury severity (p = 0.015). Mean charges for assault-related injuries also remained significantly higher than charges for unintentional injuries in multivariable models (p < 0.001). After adjusting for inflation, mean charges for pediatric firearm-related injuries increased over time (p-trend = 0.018) and were 23.1% higher in 2016 versus 2009. Mean charges increased over time among unintentional injuries (p-trend = 0.002), but not among cases with assault-related or self-inflicted injuries. CONCLUSIONS: Self-inflicted and assault-related firearm injuries are associated with higher mean healthcare charges than unintentional firearm injuries among children. Mean charges for pediatric firearm injuries have also increased over time. These findings can help guide prevention interventions aimed at reducing the substantial burden of firearm injuries among children.

Development of an online map of safe gun storage sites in Maryland for suicide prevention.

Reducing access to lethal means of self-harm is a cornerstone of suicide prevention, and temporary, voluntary gun storage outside the home is one recommended approach. With the goal of facilitating access to gun storage outside the home in Maryland, we developed an online map of gun shops and law enforcement agencies willing to offer temporary, voluntary gun storage on a case-by-case basis. This project was modelled off of prior work by the Colorado Firearm Safety Coalition. As of July 2020, 32 gun shops and 3 law enforcement agencies agreed to be listed on our map. Others were hesitant to participate due to perceived legal and logistical barriers to temporary firearm storage. We demonstrate the feasibility of creating an online map that lists organisations offering temporary gun storage in Maryland. This brief report details our process, barriers encountered, and future considerations to improve access to offsite gun storage options.

Broadening learning communities during COVID-19: developing a curricular framework for telemedicine education in neurology.

BACKGROUND: In response to the cancellation of clinical clerkships due to COVID-19, the Johns Hopkins (JH) Neurology Education Team developed a virtual elective to enhance medical students' clinical telemedicine skills and foster community between academic institutions. METHODS: This two-week clinical elective, entitled "Virtual Patient Rounds in Neurology," was administered once in April 2020 and once in May 2020. The curriculum included attending/fellow-led Virtual Rounds, Student Presentations, and Asynchronous Educational Activities. We also developed a new lecture series entitled JHNeuroChats, which consisted of live synchronous lectures presented by JH faculty and Virtual Visiting Professors. Trainees and faculty from outside institutions were invited to participate in the JHNeuroChats. Students and faculty completed pre- and post-elective surveys to assess the educational impact of the elective. Student's t-tests were used to compare scores between pre- and post-elective surveys. RESULTS: Seven JH medical students enrolled in each iteration of the elective, and an additional 337 trainees and faculty, representing 14 different countries, registered for the JHNeuroChats. We hosted 48 unique JHNeuroChats, 32 (66.7%) of which were led by invited Virtual Visiting Professors. At the end of the elective, students reported increased confidence in virtually obtaining a history (P < 0.0001) and performing a telehealth neurological physical exam (P < 0.0001), compared to the start of the course. In addition, faculty members reported increased confidence in teaching clinical medicine virtually, although these findings were not statistically significant (P = 0.15). CONCLUSIONS: Despite the constraints imposed by COVID-19, this virtual Neurology elective increased medical students' confidence in certain telemedicine skills and successfully broadened our learning community to encompass learners from around the world. As virtual medical education becomes more prevalent, it is important that we are intentional in creating opportunities for shared learning across institutions. We believe that this elective can serve as a model for these future educational collaborations.

Comorbid Psychiatric Disease Is Associated With Lower Rates of Thrombolysis in Ischemic Stroke.

BACKGROUND AND PURPOSE: Intravenous thrombolysis (IVT) improves outcomes after acute ischemic stroke but is underused in certain patient populations. Mental illness is pervasive in the United States, and patients with comorbid psychiatric disease experience inequities in treatment for a range of conditions. We aimed to determine whether comorbid psychiatric disease is associated with differences in IVT use in acute ischemic stroke. METHODS: Acute ischemic stroke admissions between 2007 and 2011 were identified in the Nationwide Inpatient Sample. Psychiatric disease was defined by International Classification of Diseases, Ninth Revision, Clinical Modification codes for secondary diagnoses of schizophrenia or other psychoses, bipolar disorder, depression, or anxiety. Using logistic regression, we tested the association between IVT and psychiatric disease, controlling for demographic, clinical, and hospital factors. RESULTS: Of the 325 009 ischemic stroke cases meeting inclusion criteria, 12.8% had any of the specified psychiatric comorbidities. IVT was used in 3.6% of those with, and 4.4% of those without, psychiatric disease (P<0.001). Presence of any psychiatric disease was associated with lower odds of receiving IVT (adjusted odds ratio, 0.80; 95% confidence interval, 0.76-0.85). When psychiatric diagnoses were analyzed separately individuals with schizophrenia or other psychoses, anxiety, or depression each had significantly lower odds of IVT compared to individuals without psychiatric disease. CONCLUSIONS: Acute ischemic stroke patients with comorbid psychiatric disease have significantly lower odds of IVT. Understanding barriers to IVT use in such patients may help in developing interventions to increase access to evidence-based stroke care.

Disparities in Breast Cancer Survival by Socioeconomic Status Despite Medicare and Medicaid Insurance.

Policy Points Patients with low socioeconomic status (SES) experience poorer survival rates after diagnosis of breast cancer, even when enrolled in Medicare and Medicaid. Most of the difference in survival is due to more advanced cancer on presentation and the general poor health of lower SES patients, while only a very small fraction of the SES disparity is due to differences in cancer treatment. Even when comparing only low- versus not-low-SES whites (without confounding by race) the survival disparity between disparate white SES populations is very large and is associated with lower use of preventive care, despite having insurance. CONTEXT: Disparities in breast cancer survival by socioeconomic status (SES) exist despite the "safety net" programs Medicare and Medicaid. What is less clear is the extent to which SES disparities affect various racial and ethnic groups and whether causes differ across populations. METHODS: We conducted a tapered matching study comparing 1,890 low-SES (LSES) non-Hispanic white, 1,824 black, and 723 Hispanic white women to 60,307 not-low-SES (NLSES) non-Hispanic white women, all in Medicare and diagnosed with invasive breast cancer between 1992 and 2010 in 17 US Surveillance, Epidemiology, and End Results (SEER) regions. LSES Medicare patients were Medicaid dual-eligible and resided in neighborhoods with both high poverty and low education. NLSES Medicare patients had none of these factors. MEASUREMENTS: 5-year and median survival. FINDINGS: LSES non-Hispanic white patients were diagnosed with more stage IV disease (6.6% vs 3.6%; p < 0.0001), larger tumors (24.6 mm vs 20.2 mm; p < 0.0001), and more chronic diseases such as diabetes (37.8% vs 19.0%; p < 0.0001) than NLSES non-Hispanic white patients. Disparity in 5-year survival (NLSES - LSES) was 13.7% (p < 0.0001) when matched for age, year, and SEER site (a 42-month difference in median survival). Additionally, matching 55 presentation factors, including stage, reduced the disparity to 4.9% (p = 0.0012), but further matching on treatments yielded little further change in disparity: 4.6% (p = 0.0014). Survival disparities among LSES blacks and Hispanics, also versus NLSES whites, were significantly associated with presentation factors, though black patients also displayed disparities related to initial treatment. Before being diagnosed, all LSES populations used significantly less preventive care services than matched NLSES controls. CONCLUSIONS: In Medicare, SES disparities in breast cancer survival were large (even among non-Hispanic whites) and predominantly related to differences of presentation characteristics at diagnosis rather than differences in treatment. Preventive care was less frequent in LSES patients, which may help explain disparities at presentation.

A systematic review of attentional biases in disorders involving binge eating.

OBJECTIVE: Attentional bias (AB) may be one mechanism contributing to the development and/or maintenance of disordered eating. AB has traditionally been measured using reaction time in response to a stimulus. Novel methods for AB measurement include eye tracking to measure visual fixation on a stimulus, and electroencephalography to measure brain activation in response to a stimulus. This systematic review summarizes, critiques, and integrates data on AB gathered using the above-mentioned methods in those with binge eating behaviors, including binge eating, loss of control eating, and bulimia nervosa. METHOD: Literature searches on PubMed and PsycInfo were conducted using combinations of terms related to binge eating and biobehavioral AB paradigms. Studies using AB paradigms with three categories of stimuli were included: food, weight/shape, and threat. For studies reporting means and standard deviations of group bias scores, Hedges' g effect sizes for group differences in AB were calculated. RESULTS: Fifty articles met inclusion criteria and were reviewed. Individuals who binge eat in the absence of compensatory behaviors show an increased AB to food cues, but few studies have examined such individuals' AB toward weight/shape and threatening stimuli. Individuals with bulimia nervosa consistently show an increased AB to shape/weight cues and socially threatening stimuli, but findings for AB to food cues are mixed. DISCUSSION: While there are important research gaps, preliminary evidence suggests that the combination of AB to disorder-specific cues (i.e., food and weight/shape) and AB toward threat may be a potent contributor to binge eating. This conclusion underscores previous findings on the interaction between negative affect and AB to disorder-specific cues. Recommendations for future research are provided.

Attentional bias to food cues in youth with loss of control eating.

Emerging data indicate that adults with binge eating may exhibit an attentional bias toward highly palatable foods, which may promote obesogenic eating patterns and excess weight gain. However, it is unknown to what extent youth with loss of control (LOC) eating display a similar bias. We therefore studied 76 youth (14.5 ± 2.3 years; 86.8% female; BMI-z 1.7 ± .73) with (n = 47) and without (n = 29) reported LOC eating. Following a breakfast to reduce hunger, youth participated in a computerized visual probe task of sustained attention that assessed reaction time to pairs of pictures consisting of high palatable foods, low palatable foods, and neutral household objects. Although sustained attentional bias did not differ by LOC eating presence and was unrelated to body weight, a two-way interaction between BMI-z and LOC eating was observed (p = .01), such that only among youth with LOC eating, attentional bias toward high palatable foods versus neutral objects was positively associated with BMI-z. These findings suggest that LOC eating and body weight interact in their association with attentional bias to highly palatable foods cues, and may partially explain the mixed literature linking attentional bias to food cues with excess body weight.

Pediatric capacity crisis: A framework and strategies to prepare for a pediatric surge.

A pediatric capacity crisis developed across the country in the Fall and Winter of 2022 due to a combination of factors, including a surge in respiratory viruses, staffing shortages, and historical closures of inpatient pediatric units. The COVID-19 pandemic and associated surge in critically ill adult patients demonstrated that health care systems and health care workers can quickly implement creative and collaborative system-wide solutions to deliver the best care possible during a capacity crisis. Similar solutions are needed to respond to future surges in pediatric volume and to maintain a high standard of care during such a surge. This paper aims to build upon insights from the COVID-19 and H1N1 pandemic responses and the 2022 pediatric capacity crisis. We provide specific recommendations addressing governmental/policy, hospital/health care system, and individual clinician strategies that can be implemented to manage future surges in pediatric patient volume.

Patients with stroke and psychiatric comorbidities have lower carotid revascularization rates.

OBJECTIVE: We investigated whether mental illness is associated with lower rates of carotid endarterectomy (CEA)/carotid artery stenting (CAS) after stroke due to carotid stenosis. METHODS: In this retrospective cross-sectional study, ischemic stroke cases due to carotid stenosis were identified in the 2007-2014 Nationwide (National) Inpatient Sample. Psychiatric conditions were identified by secondary ICD-9-CM diagnosis codes for schizophrenia/psychoses, bipolar disorder, depression, anxiety, or substance use disorders. Using logistic regression, we tested the association between psychiatric conditions and CEA/CAS, controlling for demographic, clinical, and hospital factors. RESULTS: Among 37,474 included stroke cases, 6,922 (18.5%) had a psychiatric comorbidity. The presence of any psychiatric condition was associated with lower odds of CEA/CAS (adjusted odds ratio [OR] 0.84, 95% confidence interval [CI] 0.78-0.90). Schizophrenia/psychoses (OR 0.72, 95% CI 0.55-0.93), depression (OR 0.83, 95% CI 0.75-0.91), and substance use disorders (OR 0.73, 95% CI 0.65-0.83) were each associated with lower odds of CEA/CAS. The association of mental illness and CEA/CAS was dose-dependent: compared to patients without mental illness, patients with multiple psychiatric comorbidities (OR 0.74, 95% CI 0.62-0.87) had lower odds of CEA/CAS than those with only one psychiatric comorbidity (OR 0.86, 95% CI 0.79-0.92; p value for trend <0.001). CONCLUSION: The odds of carotid revascularization after stroke is lower in patients with mental illness, particularly those with schizophrenia/psychoses, depression, substance use disorders, and multiple psychiatric diagnoses.

Effects of Endogenous Oxytocin Receptor Signaling in Nucleus Tractus Solitarius on Satiation-Mediated Feeding and Thermogenic Control in Male Rats.

Central oxytocin receptor (OT-R) signaling reduces food intake and increases energy expenditure, but the central sites and mechanisms mediating these effects are unresolved. We showed previously that pharmacological activation of OT-R in hindbrain/nucleus tractus solitarius (NTS) amplifies the intake-inhibitory effects of gastrointestinal (GI) satiation signals. Unexplored were the energetic effects of hindbrain OT-R agonism and the physiological relevance of NTS OT-R signaling on food intake and energy expenditure control. Using a virally mediated OT-R knockdown (KD) strategy and a range of behavioral paradigms, this study examined the role of endogenous NTS OT-R signaling on satiation-mediated food intake inhibition and thermogenic control. Results showed that, compared with controls, NTS OT-R KD rats consumed larger meals, were less responsive to the intake-inhibitory effects of a self-ingested preload, and consumed more chow following a 24-hour fast. These data indicate that NTS OT-R signaling is necessary for normal satiation control. Whereas both control and NTS OT-R KD rats increased core temperature following high-fat diet maintenance (relative to chow maintenance), the percent increase in core temperature was greater in control compared with NTS OT-R KD rats during the light cycle. Hindbrain oxytocin agonist delivery increased core temperature in both control and NTS OT-R KD rats and the percent increase relative to vehicle treatment was not significantly different between groups. Together, data reveal a critical role for endogenous NTS OT-R signaling in mediating the intake-inhibitory effects of endogenous GI satiation signals and in diet-induced thermogenesis.
