Xylazine has been increasingly detected in illegally manufactured fentanyl (IMF) products and overdose deaths in the United States; most xylazine-involved overdose deaths involve IMF. A convenience sample of U.S. adults aged ≥18 years was identified from those evaluated for substance use treatment during July 2022-September 2023. Data were collected using the Addiction Severity Index-Multimedia Version clinical assessment tool. Among 43,947 adults, 6,415 (14.6%) reported IMF or heroin as their primary lifetime substance-use problem; 5,344 (12.2%) reported recent (i.e., past-30-day) IMF or heroin use. Among adults reporting IMF or heroin as their primary lifetime substance-use problem, 817 (12.7%) reported ever using xylazine. Among adults reporting recent IMF or heroin use, 443 (8.3%) reported recent xylazine use. Among adults reporting IMF or heroin use recently or as their primary lifetime substance-use problem, those reporting xylazine use reported a median of two past nonfatal overdoses from any drug compared with a median of one overdose among those who did not report xylazine use; as well, higher percentages of persons who reported xylazine use reported other recent substance use and polysubstance use. Provision of nonjudgmental care and services, including naloxone, wound care, and linkage to and retention of persons in effective substance use treatment, might reduce harms including overdose among persons reporting xylazine use., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest.

Substance use often begins during adolescence, placing youths at risk for fatal overdose and substance use disorders (SUD) in adulthood. Understanding the motivations reported by adolescents for using alcohol, marijuana, and other drugs and the persons with whom they use these substances could guide strategies to prevent or reduce substance use and its related consequences among adolescents. A cross-sectional study was conducted among adolescents being assessed for SUD treatment in the United States during 2014-2022, to examine self-reported motivations for using substances and the persons with whom substances were used. The most commonly reported motivation for substance use was "to feel mellow, calm, or relaxed" (73%), with other stress-related motivations among the top reasons, including "to stop worrying about a problem or to forget bad memories" (44%) and "to help with depression or anxiety" (40%); one half (50%) reported using substances "to have fun or experiment." The majority of adolescents reported using substances with friends (81%) or using alone (50%). These findings suggest that interventions related to reducing stress and addressing mental health concerns might reduce these leading motivations for substance use among adolescents. Education for adolescents about harm reduction strategies, including the danger of using drugs while alone and how to recognize and respond to an overdose, can reduce the risk for fatal overdose., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest.

Background: Nonmedical use (NMU) of prescription psychotherapeutic drugs (PPD) may increase risk for significant morbidity and mortality in the overdose crisis., Objective: This study examines sources of PPD using real-world data from adolescents and adults reporting past 30-day NMU of PPDs., Methods: A convenience sample of individuals aged ≥10 years assessed for substance use disorders (SUD) treatment was analyzed using the 2014-2022 National Addictions Vigilance Intervention and Prevention Program datasets. PPD include prescription opioids, prescription tranquilizers/sedatives, and prescription stimulants., Results: Overall, among assessments of adolescents aged 10-18 years (N = 1991) and young adults aged 19-24 years (N = 15,166), "family/friend" (46.08-47.41 %) and "dealer" (33.82-42.71 %) were the most common sources. Among assessments of adults aged ≥25 years (N = 89,225), "own prescription" was the most common source and increased in frequency as age increased. Across all age groups, "family/friend" was the most frequent source for all drug classes (41.96-48.76 %) except for nonmedically used buprenorphine/methadone, for which "own prescription" was the most common source (51.85 %) among adults., Conclusions: Our study demonstrates heterogeneity in sources of nonmedically used PPD across age groups. Tailored prevention strategies for different age groups and improving timely access to medical care to ensure proper treatment of chronic medical conditions including SUD are needed., Competing Interests: Declaration of competing interest The authors report no declarations of interest., (Published by Elsevier Inc.)

Background Recent evaluation of rheumatic heart disease (RHD) mortality demonstrates disproportionate disease burden within the United States. However, there are few contemporary data on US children living with acute rheumatic fever (ARF) and RHD. Methods and Results Twenty-two US pediatric institutions participated in a 10-year review (2008-2018) of electronic medical records and echocardiographic databases of children 4 to 17 years diagnosed with ARF/RHD to determine demographics, diagnosis, and management. Geocoding was used to determine a census tract-based socioeconomic deprivation index. Descriptive statistics of patient characteristics and regression analysis of RHD classification, disease severity, and initial antibiotic prescription according to community deprivation were obtained. Data for 947 cases showed median age at diagnosis of 9 years; 51% and 56% identified as male and non-White, respectively. Most (89%) had health insurance and were first diagnosed in the United States (82%). Only 13% reported travel to an endemic region before diagnosis. Although 96% of patients were prescribed secondary prophylaxis, only 58% were prescribed intramuscular benzathine penicillin G. Higher deprivation was associated with increasing disease severity (odds ratio, 1.25; 95% CI, 1.08-1.46). Conclusions The majority of recent US cases of ARF and RHD are endemic rather than the result of foreign exposure. Children who live in more deprived communities are at risk for more severe disease. This study demonstrates a need to improve guideline-based treatment for ARF/RHD with respect to secondary prophylaxis and to increase research efforts to better understand ARF and RHD in the United States.

Background: Extensive evidence indicates that Collaborative Chronic Care Models (CCMs) improve outcome in chronic medical conditions and depression treated in primary care. Beginning with an evidence synthesis which indicated that CCMs are also effective for multiple mental health conditions, we describe a multistage process that translated this knowledge into evidence-based health system change in the US Department of Veterans Affairs (VA)., Evidence Synthesis: In 2010, recognizing that there had been numerous CCM trials for a wide variety of mental health conditions, we conducted an evidence synthesis compiling randomized controlled trials of CCMs for any mental health condition. The systematic review demonstrated CCM effectiveness across mental health conditions and treatment venues. Cumulative meta-analysis and meta-regression further informed our approach to subsequent CCM implementation., Policy Impact: In 2015, based on the evidence synthesis, VA Office of Mental Health and Suicide Prevention (OMHSP) adopted the CCM as the model for their outpatient mental health teams., Randomized Implementation Trial: In 2015-2018 we partnered with OMHSP to conduct a 9-site stepped wedge implementation trial, guided by insights from the evidence synthesis., Scale-Up and Spread: In 2017 OMHSP launched an effort to scale-up and spread the CCM to additional VA medical centers. Seventeen facilitators were trained and 28 facilities engaged in facilitation., Discussion: Evidence synthesis provided leverage for evidence-based policy change. This formed the foundation for a health care leadership/researcher partnership, which conducted an implementation trial and subsequent scale-up and spread effort to enhance adoption of the CCM, as informed by the evidence synthesis.

Objective: Guidelines recommend withholding biologic therapies before hip and knee arthroplasty, yet evidence to inform optimal timing is limited. The aim of this study was to determine whether withholding abatacept infusions is associated with lower risk of adverse postoperative outcomes., Methods: This retrospective cohort study, which used US Medicare and Truven MarketScan administrative data from January 2006 to September 2015, evaluated adults with rheumatoid arthritis who received intravenous abatacept (precisely dated in claims data) within 6 months of elective primary or revision hip or knee arthroplasty. Propensity weighted analyses using inverse probability weights compared the risk of 30-day hospitalized infection and 1-year prosthetic joint infection (PJI) between patients with different abatacept stop timing (time between last infusion and surgery). Secondary analyses evaluated nonurinary hospitalized infections and 30-day readmissions., Results: After 1,939 surgeries among 1,780 patients, there were 175 hospitalized infections (9.0%), 115 nonurinary hospitalized infections (5.9%), 39 PJIs (2.4/100 person-years), and 114/1,815 30-day readmissions (6.3%). There were no significant differences in outcomes with abatacept stop timing <4 weeks (1 dosing interval) versus 4-8 weeks (hospitalized infection odds ratio [OR] 0.93 [95% confidence interval (95% CI) 0.65-1.34]; nonurinary hospitalized infection OR 0.93 [95% CI 0.60-1.44]; PJI hazard ratio 1.29 [95% CI 0.62-2.69]; 30-day readmission OR 1.00 [95% CI 0.65-1.54]). Similarly, there were no significant differences in outcomes with abatacept stop timing <4 weeks versus ≥8 weeks. Glucocorticoid use >7.5 mg/day was associated with greater risk of hospitalized infection (OR 2.19 [95% CI 1.28-3.77]) and nonurinary hospitalized infection (OR 2.38 [95% CI 1.22-4.64])., Conclusion: Compared to continuing intravenous abatacept, withholding abatacept for ≥4 weeks (one dosing interval) before surgery was not associated with a lower risk of hospitalized infection, nonurinary hospitalized infection, PJI, or 30-day readmission., (© 2019, American College of Rheumatology.)

The Collaborative Care Model (CCM) is an evidence-based approach for structuring care for chronic health conditions. Attempts to implement CCM-based care in a given setting depend, however, on the extent to which care in that setting is already aligned with the specific elements of CCM-based care. We therefore interviewed staff from ten outpatient mental health teams in the US Department of Veterans Affairs to determine whether care delivery was consistent or inconsistent with CCM-based care in those settings. We discuss implications of our findings for future attempts to implement CCM-based outpatient mental health care.

Importance: Collaborative chronic care models (CCMs) have extensive randomized clinical trial evidence for effectiveness in serious mental illnesses, but little evidence exists regarding their feasibility or effect in typical practice conditions., Objective: To determine the effectiveness of implementation facilitation in establishing the CCM in mental health teams and the impact on health outcomes of team-treated individuals., Design, Setting, and Participants: This quasi-experimental, randomized stepped-wedge implementation trial was conducted from February 2016 through February 2018, in partnership with the US Department of Veterans Affairs (VA) Office of Mental Health and Suicide Prevention. Nine facilities were enrolled from all VA facilities in the United States to receive CCM implementation support. All veterans (n = 5596) treated by designated outpatient general mental health teams were included for hospitalization analyses, and a randomly selected sample (n = 1050) was identified for health status interviews. Individuals with dementia were excluded. Clinicians (n = 62) at the facilities were surveyed, and site process summaries were rated for concordance with the CCM process. The CCM implementation start time was randomly assigned across 3 waves. Data analysis of this evaluable population was performed from June to September 2018., Interventions: Internal-external facilitation, combining a study-funded external facilitator and a facility-funded internal facilitator working with a designated team for 1 year., Main Outcomes and Measures: Facilitation was hypothesized to be associated with improvements in both implementation and intervention outcomes (hybrid type II trial). Implementation outcomes included the clinician Team Development Measure (TDM) and proportion of CCM-concordant team care processes. The study was powered for the primary health outcome, mental component score (MCS). Hospitalization rate was derived from administrative data., Results: The veteran population (n = 5596) included 881 women (15.7%), and the mean (SD) age was 52.2 (14.5) years. The interviewed sample (n = 1050) was similar but was oversampled for women (n = 210 [20.0%]). Facilitation was associated with improvements in TDM subscales for role clarity (53.4%-68.6%; δ = 15.3; 95% CI, 4.4-26.2; P = .01) and team primacy (50.0%-68.6%; δ = 18.6; 95% CI, 8.3-28.9; P = .001). The percentage of CCM-concordant processes achieved varied, ranging from 44% to 89%. No improvement was seen in veteran self-ratings, including the primary outcome. In post hoc analyses, MCS improved in veterans with 3 or more treated mental health diagnoses compared with others (β = 5.03; 95% CI, 2.24-7.82; P < .001). Mental health hospitalizations demonstrated a robust decrease during facilitation (β = -0.12; 95% CI, -0.16 to -0.07; P < .001); this finding withstood 4 internal validity tests., Conclusions and Relevance: Implementation facilitation that engages clinicians under typical practice conditions can enhance evidence-based team processes; its effect on self-reported overall population health status was negligible, although health status improved for individuals with complex conditions and hospitalization rate declined., Trial Registration: ClinicalTrials.gov Identifier: NCT02543840.

Natural resources across the United States are increasingly managed at the landscape scale through cooperation among multiple organizations and landowners. United States Department of Agriculture Forest Service (USFS) agency leaders have widely promoted this approach since 2009 when Secretary of Agriculture Vilsack called for "all lands" management. Landscape scale projects have been undertaken to address multiple goals such as single species conservation, resilience to fire, invasive species eradication, and others. The West Virginia Restoration Venture (WVRV)-one of five landscape scale conservation projects funded 2014-2016 across the Northeast and Midwest and known as "Joint Chiefs'" projects-was evaluated by an interdisciplinary team of USFS employees to gain insight into how cross-boundary landscape scale conservation projects are implemented in the region. In this paper, the team used qualitative interview data from project participants to explore processes related to developing a shared vision for the landscape, implementation priorities, and methods to work across institutional and property ownership boundaries. Grounded in the landscape and collaborative resource management literatures, the report shows how established inter-organizational networks, flexible approaches to management, and a "shelf-stock" of ready-to-implement projects led to on-the-ground success. The authors provide insight about factors that constrain and facilitate the implementation of landscape scale conservation projects that have multiple goals, landowners, and organizational partners.

Most health-care professionals are trained to promote and maintain life and often have difficulty when faced with the often rapid decline and death of people with terminal illnesses such as amyotrophic lateral sclerosis (ALS). By contrast, data suggest that early and open discussion of end-of-life issues with patients and families allows time for reflection and planning, can obviate the introduction of unwanted interventions or procedures, can provide reassurance, and can alleviate fear. Patients' perspectives regarding end-of-life interventions and use of technologies might differ from those of the health professionals involved in their care, and health-care professionals should recognise this and respect the patient's autonomy. Advance care directives can preserve autonomy, but their legal validity and use varies between countries. Clinical management of the end of life should aim to maximise quality of life of both the patient and caregiver and, when possible, incorporate appropriate palliation of distressing physical, psychosocial, and existential distress. Training of health-care professionals should include the development of communication skills that help to sensitively manage the inevitability of death. The emotional burden for health-care professionals caring for people with terminal neurological disease should be recognised, with structures and procedures developed to address compassion, fatigue, and the moral and ethical challenges related to providing end-of-life care., (Copyright © 2015 Elsevier Ltd.

As individuals with HIV are living longer with less morbidity, developing interventions that address co-morbidities are essential. Psychological distress symptoms fluctuate throughout HIV infection and interrupt self-care practices. This pilot study was conducted to test the implementation of a clinic-recruited sample to participate in a community-based urban farming intervention, and assess the efficacy of reducing psychological distress symptoms. While the changes were not statistically significant, participants reported less distress symptoms, improved overall general health, and reduced frequency of illicit drug use. These findings support the development of a larger scale study to examine the impact of this nontraditional intervention.

The total cost of employee absence for many employers is high, and the correlation between employee health and disability is clear. This article reviews several challenges employers face in managing employee health and absence in a well-integrated manner. Although such an undertaking is not easy, the additional cost national health care reform may bring makes the interrelationship between employer profitability and employee absence, health and disability more crucial than ever for employers to recognize and manage.
