The Effects of an Electronic Medical Record Prompt on Documentation of Firearm Screening in and Adolescent Primary Care Setting.

PURPOSE: There is limited evidence as to how to facilitate health care providers (HCPs) addressing firearm injury prevention during routine visits. The purpose of this project was to examine whether including a screening question about firearms in the home in the routine care template increases the screening of youth access to firearms. METHODS: A pre-post approach chart review was conducted for youth 12-21 years old. Outcomes included HCP documentation of screening for the presence of firearms and whether counseling caregivers on safer storage practices was delivered. RESULTS: HCPs documented screening adolescents for firearms 85% after the addition of the prompt compared to 25% prior to the change (p < .001). The presence of the screening prompt also led to an increase in the delivery of safe storage counseling (p = .035). DISCUSSION: Altering the EMR template increased HCP documentation of the presence of firearms in the home while also increasing firearm injury prevention counseling delivered to caregivers.

Which Types of Providers Have Firearm Discussions in a Pediatric Primary Care Clinic?

OBJECTIVE: Safe firearm storage decreases self-inflicted and unintentional firearm injury in youth. Medical providers are well-positioned to discuss safe firearm storage with families. The primary objective of this study was to determine which providers are most likely to discuss firearms with their patients. Our secondary objective was to determine whether providers were more likely to discuss firearms with patients at elevated suicide risk. METHODS: This was a retrospective chart review of primary care well child visits occurring January-December 2019 in a large, urban academic clinic. We documented provider-type and training level (exposure); any documentation of firearms in the chart (counseling, screening) was considered as having a firearm discussion (outcome). We also collected demographics, patient mental health history, PHQ-9 scores, and assessed suicide risk. RESULTS: Of the 743 charts reviewed, firearms were discussed in 9% (n=66). Medical students were most likely to discuss firearms (15%), attending physicians were least likely (1%, p < 0.001). Providers did not discuss firearms more frequently among youth at elevated suicide risk. CONCLUSION: Though providers do not frequently discuss and document firearm discussions overall, the higher rates among medical students is promising. Given the lethality of firearms in a suicide attempt, the lack of firearm safety discussions with those at elevated suicide risk was concerning. Further study should evaluate factors that facilitate discussions in this cohort and identify strategies to improve counseling among more senior providers. WHAT'S NEW: Pediatric providers have an opportunity to counsel families about the risk of firearm access. We found that trainees are most likely to counsel families about firearms, and that providers are not more likely to counsel youth at elevated suicide risk.

Firearm businesses as partners in suicide prevention: a cross-sectional study of the Gun Shop Project in Colorado, USA.

BACKGROUND: The Gun Shop Project aims to reduce firearm suicide and is widely implemented in the USA, yet little is known about the core firearm business practices and behaviours that might contribute to preventing firearm suicide. METHODS: Owners or managers of all firearm businesses identified as participants in Colorado's Gun Shop Project were invited to respond to a questionnaire. Data collection occurred from March to May 2021. Analyses included unweighted descriptive statistics with CIs and Pearson χ2 tests for categorical associations. RESULTS: 54 firearm businesses participated (response rate: 28%). Under half reported practices that are Gun Shop Project core aspects (range: 14%-45%). 22% of businesses frequently engaged customers on the importance of safe firearm storage in suicide prevention while 26% had denied a firearm sale and 14% had assisted with temporary secure storage in the past year with customers perceived to be in suicidal crisis. However, high proportions reported willingness to engage in these behaviours if a customer was in crisis: 74% were willing to refuse a sale of a firearm or ammunition, 70% were willing to discuss temporary secure storage options and 70% were willing to direct customers to mental health services. CONCLUSIONS: This study suggests that efforts to continue educating and involving firearm businesses may have an impact on the adoption of organisational suicide prevention practices and behaviours. Ongoing efforts are needed to understand core components of Gun Shop Project to inform standardised recommendations for effective firearm business practices that prevent firearm suicide.

Acceptability and feasibility of video-based firearm safety education in a Colorado emergency department for caregivers of adolescents in firearm-owning households.

BACKGROUND: Easy firearm access increases injury risk among adolescents. We evaluated the acceptability and feasibility of improving knowledge of a 3 min safe firearm storage education video in the paediatric emergency department. METHODS: We conducted a single-centre block trial in a large paediatric emergency department (August 2020-2022). Participants were caregivers of adolescents (10-17 years) in firearm-owning households. First block participants (control) completed a baseline survey about child safety behaviours (including firearms). Second block participants (intervention) completed a baseline survey, watched the safe firearm storage video and evaluated acceptability. Participants completed a 3-month follow-up survey about firearm safety behaviours and knowledge recall. Demographic and clinical variables were compared between the intervention and control groups using Fisher's exact and χ2 tests. McNemar's test was used to compare firearm storage behaviours at the initial and 3-month visit within each group. RESULTS: Research staff approached 1264 caregivers; 371 consented to participate (29.4%) and 144 (38.8%) endorsed firearm ownership. There were 95 participants in the control group and 62 in the intervention group. Follow-up was lower in the intervention group (53.7% vs 37.1%, p=0.04). Among participants viewing the video, 80.3% liked the video and 50.0% felt they learnt something new from the video. CONCLUSIONS: Video-based firearm education in a paediatric emergency department is acceptable among a population of caregivers of adolescents with household firearms. This is a higher-risk group that may uniquely benefit from consistent education in the paediatric emergency department. Further study with larger populations is needed to evaluate intervention effectiveness. TRIAL REGISTRATION: The study was registered with ClinicalTrials.gov (NCT05168878).

Gun Carrying Among Military-Connected Youth With Past-Year Suicidal Ideation and Suicide Plans.

This cross-sectional study compares gun carrying practices and participation in violence prevention programs among youth with vs without a parent in the US military.

Development of Potent Mcl-1 Inhibitors: Structural Investigations on Macrocycles Originating from a DNA-Encoded Chemical Library Screen.

Evasion of apoptosis is critical for the development and growth of tumors. The pro-survival protein myeloid cell leukemia 1 (Mcl-1) is an antiapoptotic member of the Bcl-2 family, associated with tumor aggressiveness, poor survival, and drug resistance. Development of Mcl-1 inhibitors implies blocking of protein-protein interactions, generally requiring a lengthy optimization process of large, complex molecules. Herein, we describe the use of DNA-encoded chemical library synthesis and screening to directly generate complex, yet conformationally privileged macrocyclic hits that serve as Mcl-1 inhibitors. By applying a conceptual combination of conformational analysis and structure-based design in combination with a robust synthetic platform allowing rapid analoging, we optimized in vitro potency of a lead series into the low nanomolar regime. Additionally, we demonstrate fine-tuning of the physicochemical properties of the macrocyclic compounds, resulting in the identification of lead candidates 57/59 with a balanced profile, which are suitable for future development toward therapeutic use.

Evaluating the function and psychometric properties of a violence risk screening tool in a community sample of adolescents.

Youth violence continues to be widespread. Despite numerous evidence-based programs that reduce youth violence, objective ways to identify youth in need of services is lacking. Few screening tools are available that enables practitioners or community organizations to predict who may perpetrate serious violence. The Violence Injury Protection and Risk Screen (VIPRS) is a previously validated screening tool providing a framework to address youth violence. The purpose of this study is to evaluate the psychometric properties of the VIPRS in a community sample for use in multiple settings. Youth participating in a community-focused youth violence prevention intervention served as the study subjects. Households with youth ages 10-17 were eligible to participate. Study personnel verbally asked youth survey questions and recorded answers on a laptop. Multiple measures-including risk factors for violent behavior as well as, violence and delinquency scales, were asked. Eleven hundred youth participated. Mean age was 13.3; 53% female, 26% Black, 58% Hispanic, 11% more than 1 race. Twenty percent screened positive on the VIPRS-28% male versus 13% female (p = .000). Violence-related behaviors were common: 33% were in a physical fight, 27% experienced cyberbullying victimization, and 9% perpetrated a minor assault. The VIPRS demonstrated robust criterion validity with significant correlation to multiple violence measures (0.3-0.6). Scoring positive on the VIPRS conveyed increased odds of reporting other violent behaviors, such as perpetrating physical aggression (OR: 7 [95% CI: 5.1-11.5]). Overall, the VIPRS performed well in a community sample of youth further validating its psychometric functioning while demonstrating the potential for use in settings beyond healthcare.

Suicide and Suicide Risk in Adolescents.

Suicide is the second leading cause of death for 10- to 24-year-olds in the United States and is a global public health issue, with a recent declaration of a National State of Emergency in Children's Mental Health by the American Academy of Pediatrics, American Academy of Child and Adolescent Psychiatry, and Children's Hospital Association. This clinical report is an update to the previous American Academy of Pediatrics clinical report, "Suicide and Suicide Attempts in Adolescents." Because pediatricians and pediatric health care providers are at the front line of care for adolescents amid a child and adolescent mental health crisis, and because of the chronic and severe shortage of mental health specialists, it is important that pediatric health care providers become facile with recognizing risk factors associated with suicidality and at-risk populations, screening and further assessment of suicidality as indicated, and evidence-based interventions for patients with suicidal ideation and associated behaviors. Suicide risk can be mitigated by appropriate screening, bolstering of protective factors, indicated treatment, community resources, and referrals to mental health providers when available.

One Step Closer to Safer: Counseling Outcomes from American Academy of Pediatrics Firearm Safe Storage Education Training.

OBJECTIVE: To assess pre and postself-reported counseling outcomes for Safer: Storing Firearms Prevents Harm, an American Academy of Pediatrics universal firearm safe storage counseling training for pediatric clinicians providing health maintenance in outpatient settings. STUDY DESIGN: Safer was developed by a national multidisciplinary committee of firearm injury prevention experts with input from firearm-owning families and launched in June 2021. Pediatric clinicians completed baseline and 1-month posttraining surveys after signing up for the Pedialink course from February through June 2022. Primary outcomes included self-reported measures of counseling self-efficacy and frequency. Wilcoxon matched-pairs signed-rank tests compared outcome distributions at baseline and follow-up. Two adjusted, multilevel mixed-effects regression models were conducted. RESULTS: Of 230 clinicians who completed baseline surveys, 146 (64%) completed 1-month postsurveys. Regional representation included Southeast = 67 (46%), Northeast = 24 (16%), Midwest = 21 (14%), Pacific = 15 (10%), Southwest = 11 (8%), and Rocky Mountain = 8 (5%). At follow-up, there was significant improvement in both the distribution of self-efficacy (median [first Quartile-third Quartile = 50 [20-70] at baseline and 80 [60-85] at follow-up; P < .001) and self-reported counseling frequency (median [first Quartile-third Quartile] = 10 [0-50] at baseline and 50 [10-80] at follow-up; P < .001). Adjusted regression model results suggested that self-efficacy significantly improved from baseline to follow-up (time coefficient 25.3; 95% CI = [21.0, 29.5]; P < .001) as did counseling frequency (time coefficient 13.6; 95% CI = [9.2, 18.0]; P < .001). CONCLUSIONS: Significant improvement in self-reported counseling self-efficacy and frequency was demonstrated 1 month following Safer training.

Intimate Partner Violence: Role of the Pediatrician.

The American Academy of Pediatrics and its members recognize the importance of improving the physician's ability to recognize intimate partner violence (IPV) and understand its effects on child health and development and its role in the continuum of family violence. Pediatricians are in a unique position to identify IPV survivors in pediatric settings, to evaluate and treat children exposed to IPV, and to connect families with available local and national resources. Children exposed to IPV are at increased risk of being abused and neglected and are more likely to develop adverse health, behavioral, psychological, and social disorders later in life. Pediatricians should be aware of these profound effects of exposure to IPV on children and how best to support and advocate for IPV survivors and their children.

Acceptability of Long Versus Short Firearm Safety Education Videos in the Emergency Department: A Pilot Randomized Controlled Trial.

STUDY OBJECTIVE: Safe firearm storage is protective against pediatric firearm injuries. We sought to compare a 3-minute versus 30-second safe firearm storage video in terms of acceptability of video content and use in the pediatric emergency department (PED). METHODS: We conducted a randomized controlled trial in a large PED (from March to September 2021). Participants were English-speaking caregivers of noncritically ill patients. Participants were surveyed about child safety behaviors (including firearm storage), then shown 1 of 2 videos. Both videos described safe storage principles; the 3-minute video included temporary firearm removal and a survivor testimonial. The primary outcome was acceptability, measured by responses on a 5-point Likert scale (strongly disagree to strongly agree). A survey at 3 months evaluated information recall. Baseline characteristics and outcomes were compared between groups using Pearson chi-squared, Fisher exact, and Wilcoxon Mann Whitney tests as appropriate. Absolute risk difference for categoric variables and mean difference for continuous variables are reported with 95% confidence interval (CI). RESULTS: Research staff screened 728 caregivers; 705 were eligible and 254 consented to participate (36%); 4 withdrew. Of 250 participants, most indicated acceptability in terms of setting (77.4%) and content (86.6%), and doctors discussing firearm storage (78.6%), with no difference between groups. More caregivers viewing the longer video felt the length appropriate (99.2%) compared with the shorter video (81.1%, difference 18.1%, 95% CI 11.1 to 25.1). CONCLUSIONS: We show that video-based firearm safety education is acceptable among study participants. This can provide consistent education to caregivers in PEDs and needs further study in other settings.

Informing Use of the Patient Health Questionnaire-2 to Detect Moderate or Greater Depression Symptoms in Adolescents and Young Adults in Outpatient Primary Care.

OBJECTIVE: We compared the Patient Health Questionnaire (PHQ)-2 to the PHQ-9 and examined the implications of using various cutoff scores on the PHQ-2 to detect moderate or greater depressive symptoms on the PHQ-9. We hypothesized that a cutoff score of ≥2 would be optimal for detecting scores of ≥10 on the PHQ-9. METHODS: Demographic and depression screening data from 3,256 routine preventive visits for patients aged 12-25 years at the adolescent and young adult clinic at Children's Hospital Colorado between March 2017 and July 2019 were collected retrospectively. Patients completed routine depression screening at 2,183 visits which were included for analysis. PHQ-2 scores and PHQ-9 scores were calculated for each included patient visit. Associations between different PHQ-2 cutoff scores and moderate or greater depressive symptoms on the PHQ-9 (≥10) were evaluated. RESULTS: A PHQ-2 score ≥2 had a sensitivity of 89% and specificity of 83% for detecting patients with moderate or greater depressive symptoms on the PHQ-9. On a receiver operating characteristic curve, a PHQ-2 cutoff of ≥2 optimized sensitivity and specificity. Analysis of gender and ethnic/racial subgroups demonstrated the same optimal cutoff score for each group studied. For patients aged 21 years and older a PHQ-2 cutoff of ≥3 was most accurate. DISCUSSION: Lowering the positive PHQ-2 cutoff to ≥2 has several clinical advantages, including increased detection of moderate or greater depressive symptoms and depressive disorders. Providers may increase identification of depression by making this change particularly if they follow a positive PHQ-2 with a full PHQ-9.

Utilizing the Electronic Medical Record to Enhance Health Care Provider Delivery of Messages About the Safe Storage of Firearms.

The goal of this project was to determine whether screening youth and parents for firearm presence and imbedding those results in the electronic medical record (EMR) increased health care provider (HCP) documentation of firearms and subsequent delivery of a safe storage message. The study took place in a large adolescent medicine practice. Fifty-six dyads (40% of eligible) were randomized to usual care or the intervention, in which screening results for firearms were imbedded in the EMR. Health care providers delivered a safe storage message to 20% of controls and 51.2% in the intervention (P = .04). When HCPs documented the delivery of a safe storage message, 64% of parents recalled hearing it, compared with only 36% when there was no documentation (P = .012). Therefore, we found that incorporating firearm screening into the EMR increases the attention HCPs give to delivering a firearm safe storage message and correlates with parents recalling having heard a safe storage message.

Implementation of a youth violence prevention programme in primary care.

BACKGROUND AND OBJECTIVES: Youth violence is an alarming public health problem, yet, violence screening and interventions are not systematically offered in primary care (PC). This paper describes data from a pilot effectiveness-implementation trial of an efficacious youth violence prevention programme (SafERteens). METHODS: The study was conducted in two PC clinics: a university-affiliated satellite clinic and a community health centre. In phase 1, we obtained stakeholder feedback to customise the SafERteens package and enrolled a comparison group of adolescents (age 14-18) seeking care in two clinics. In phase 2, clinical staff delivered the SafERteens-PC intervention with adolescents, which is a single, behavioural health therapy session delivered one-on-one from clinic providers to youth patients, followed by text message (TM) reminders. In phase 3, we assessed planned maintenance. All participants reported past-year violent behaviour at intake and completed a 3-month follow-up assessment. RESULTS: Based on stakeholder interviews (n=13), we created a web-based SafERteens-PC programme package, including a three-item past-year violence screen, 30 min motivational interviewing-based brief intervention delivery tool, training videos and 2 months of TM boosters. We enrolled a comparison group (n=49) first, then an intervention group (n=61). Intervention delivery characteristics varied by clinic, including completion of intervention (75.9%; 62.5%), modality (100% delivered via telehealth; 60% via telehealth/40% in-person) and enrolment in TMs (81.8%; 55.0%); 91.8% completed the follow-up. Using an intention-to-treat approach, the intervention group showed significantly greater reductions in severe peer aggression (p<0.05), anxiety (p<0.05) and substance use consequences (p<0.05) relative to the comparison group. Participant and staff feedback were positive and identified challenges to long-term implementation, such as lack of availability of reimbursement for youth violence prevention. CONCLUSIONS: If these challenges could be addressed, routine provision of behavioural health services for violence prevention in PC could have high impact on health outcomes for adolescents.

Discovery of Novel UDP-N-Acetylglucosamine Acyltransferase (LpxA) Inhibitors with Activity against Pseudomonas aeruginosa.

This study describes a novel series of UDP-N-acetylglucosamine acyltransferase (LpxA) inhibitors that was identified through affinity-mediated selection from a DNA-encoded compound library. The original hit was a selective inhibitor of Pseudomonas aeruginosa LpxA with no activity against Escherichia coli LpxA. The biochemical potency of the series was optimized through an X-ray crystallography-supported medicinal chemistry program, resulting in compounds with nanomolar activity against P. aeruginosa LpxA (best half-maximal inhibitory concentration (IC50) <5 nM) and cellular activity against P. aeruginosa (best minimal inhibitory concentration (MIC) of 4 µg/mL). Lack of activity against E. coli was maintained (IC50 > 20 µM and MIC > 128 µg/mL). The mode of action of analogues was confirmed through genetic analyses. As expected, compounds were active against multidrug-resistant isolates. Further optimization of pharmacokinetics is needed before efficacy studies in mouse infection models can be attempted. To our knowledge, this is the first reported LpxA inhibitor series with selective activity against P. aeruginosa.

Adapting Safety Check as a Universal Suicide Prevention Strategy in Pediatric Primary Care.

OBJECTIVE: The presence of unlocked firearms in the home is associated with increased risk of suicide and unintentional injury in youth. We adapted an evidence-based program for promoting safe firearm storage, Safety Check, to enhance its acceptability as a universal suicide prevention strategy in pediatric primary care. METHODS: We applied ADAPT-ITT, an established adaptation framework, to guide iterative program adaptation with ongoing input from key stakeholders. The present study describes 2 phases of ADAPT-ITT: the Production phase (generating adaptations) and the Topical Experts phase (gathering stakeholder feedback on adaptations). After generating proposed program adaptations based on 3 inputs (stakeholder feedback collected in a prior study, the behavioral science literature, and best practices in pediatric medicine), we elicited feedback from stakeholders with firearm expertise. The adaptations included changes such as clarifying firearm ownership will not be documented in the medical record and offering follow-up reminders. We also crowdsourced feedback from 337 parents to select a new name and program logo. RESULTS: Saturation was reached with 9 stakeholders. Feedback confirmed the value of adaptations that: 1) considered context (eg, reason for ownership), 2) promoted parent autonomy in decision-making, and 3) ensured privacy. The most preferred program name was Suicide and Accident prevention through Family Education (SAFE) Firearm. CONCLUSIONS: Guided by an established adaptation framework that prioritized multistage stakeholder feedback, adaptations to the original Safety Check were deemed acceptable. We plan to test the SAFE Firearm program as a universal suicide prevention strategy in pediatric primary care via a hybrid effectiveness-implementation trial.

Risk and Protective Factors Associated with Youth Firearm Access, Possession or Carrying.

Firearm homicide and suicide are the leading causes of violence-related injury deaths among U.S. youth. However, evaluations of the effectiveness of firearm violence prevention programs and strategies to reducing youth firearm violence are limited. To help inform and evaluate such efforts, this study aimed to identify risk and protective factors associated with youth firearm access, possession or carrying (for reasons other than hunting or target shooting) among a sample of U.S. urban youth in the Mountain West. Findings show the influence that youth violence risk (e.g., having friends engaged in delinquency; violence; drug sales; gang fights; exposure to violence; screening positive for violence risk) can have on youth firearm access, possession or carrying. Implications for prevention and intervention are discussed.

Machine Learning on DNA-Encoded Libraries: A New Paradigm for Hit Finding.

DNA-encoded small molecule libraries (DELs) have enabled discovery of novel inhibitors for many distinct protein targets of therapeutic value. We demonstrate a new approach applying machine learning to DEL selection data by identifying active molecules from large libraries of commercial and easily synthesizable compounds. We train models using only DEL selection data and apply automated or automatable filters to the predictions. We perform a large prospective study (∼2000 compounds) across three diverse protein targets: sEH (a hydrolase), ERα (a nuclear receptor), and c-KIT (a kinase). The approach is effective, with an overall hit rate of ∼30% at 30 µM and discovery of potent compounds (IC50 < 10 nM) for every target. The system makes useful predictions even for molecules dissimilar to the original DEL, and the compounds identified are diverse, predominantly drug-like, and different from known ligands. This work demonstrates a powerful new approach to hit-finding.
