BACKGROUND:Individuals with opioid use disorder have high rates of hospital admissions, which represent a critical opportunity to engage patients and initiate medications for opioid use disorder (MOUD). However, few patients receive MOUD and, even if MOUD is initiated in the hospital, patients may encounter barriers to continuing MOUD in the community. OBJECTIVE:Describe hospital providers' experiences and perspectives to inform initiatives and policies that support hospital-based MOUD initiation and continuation in community treatment programs. DESIGN/METHODS:As part of a broader implementation study focused on inpatient MOUD (NCT#04921787), we conducted semi-structured interviews with hospital providers. PARTICIPANTS/METHODS:Fifty-seven hospital providers from 12 community hospitals. APPROACH/METHODS:Thematic analysis examined an emergent topic on challenges transitioning patients to outpatient MOUD treatment and related impacts on MOUD initiation by inpatient providers. KEY RESULTS/RESULTS:Participants described structural barriers to transitioning hospitalized patients to continuing outpatient MOUD including (a) limited outpatient buprenorphine prescriber availability, (b) the siloed nature of addiction treatment, and (c) long wait times. As a result of observing these structural barriers, participants experienced a sense of futility that deterred them from initiating MOUD. Participants proposed strategies that could better support these patient transitions, including developing partnerships between hospitals and outpatient addiction treatment and supporting in-reach services from community providers. CONCLUSIONS:We identified concerns about inadequate and inaccessible community-based care and transition pathways that discouraged hospital providers from prescribing MOUD. As hospital-based opioid treatment models continue to expand, programmatic and policy strategies to support inpatient transitions to outpatient addiction treatment are needed.

OBJECTIVE:To increase the rate of low dose aspirin (LDA) counseling and treatment in patients with 2 or more moderate risk factors of preeclampsia(PMRF) from 9% to 50% within a four-month period after implementation of interventions. STUDY DESIGN/METHODS:A single-institution quality improvement initiative aimed at LDA screening and counseling of those with PMRF. Two groups were evaluated: pre-intervention (January - April 2022) and post-intervention (January - April 2023). This initiative focused on identifying PMRF and monitoring rates of LDA counseling and treatment. Rates were assessed at two-week intervals and presented on a run chart to visualize trends and measure progress over time. Providers underwent education utilizing preeclampsia (PEC) screening flowsheets and integrated a clinical decision-making (CDM) tool in initial prenatal visit documentation using a smart-tool. Patients were provided with educational flyers. RESULTS:In the pre-intervention group (n=126), 8.7% of patients received counseling on PMRF risk factors and LDA use, 7.9% were treated with LDA. In the post-intervention group (n=112) 52.7% of patients received counseling on PMRF risk factors and LDA use, and 35.7% were treated with LDA. There was an 83.5% increase in the percentage of patients counseled following intervention implementation. A progressive increase was noted in counseling rates within the 18 weeks post-intervention. CONCLUSION/CONCLUSIONS:Integrating PEC screening flowsheets, clinical decision-making tools, and patient education flyers effectively enhances LDA counseling for patients with ≥2 PMRF with additional benefits seen in high-risk patients. These interventions offer a replicable model to enhance guideline adherence and reduce preeclampsia risk in vulnerable populations.

AIMS/OBJECTIVE:Carotid-femoral pulse wave velocity (cfPWV) is a representative measure of central arterial stiffness and an independent predictor of cardiovascular disease (CVD). Femoral-ankle PWV (faPWV) represents peripheral arterial stiffness, but its association with CVD has not been specifically investigated. METHODS:We analyzed 3,402 ARIC participants without prior coronary heart disease (CHD), heart failure (HF), or stroke at Visit 5 (2011-13) (mean age 74.8 [4.9] years, 36.1% male, 22.0% Black). faPWV and cfPWV were measured by Omron VP-1000 Plus. The primary outcome was CVD (CHD, HF, and stroke). We used multivariable Cox proportional hazards models. RESULTS:During a median 9.0-year follow-up, 607 CVD events occurred. Overall, faPWV showed an inverse association with CVD, with hazard ratio (HR) for top vs. bottom quartile 0.80 (95%CI 0.64-1.01) and p-for-trend 0.017 in Model 1 (demographically adjusted) and HR 0.86 (0.68-1.09) and p-for-trend 0.096 in Model 2 (further adjusted for CVD risk factors). In contrast, cfPWV was positively associated with CVD in both Models (HR for top vs. bottom quartile 1.22 [0.95-1.56], p-for-trend=0.043 in Model 2). The ratio of cfPWV to faPWV ("cf-fa ratio") showed a stronger association with CVD (HR 1.37 [1.07-1.74], p-for-trend=0.005) than cfPWV. Examining CVD subtypes, the significant contrast in Model 2 was cf-fa ratio and HF. CONCLUSIONS:faPWV showed a borderline significant inverse association with CVD, and cf-fa ratio appeared more strongly associated with CVD than cfPWV. Our findings indicate distinct prognostic implications of central vs. peripheral arterial stiffness and support cf-fa ratio as an alternative measure for CVD risk assessment.

OBJECTIVE:Primary care-based literacy promotion enhances caregiver-child shared reading and child language outcomes, yet variation in implementation may dilute its impact. This study examines expert perspectives on intended outcomes of literacy promotion, as well as its core components, those necessary to achieve intended outcomes, and components that are recommended but adaptable to context. METHODS:We purposively sampled healthcare and policy experts in primary care-based literacy promotion from the U.S. and Canada for online, in-depth interviews. Interviews were recorded, transcribed verbatim, and analyzed iteratively engaging emergent and a priori codes based on the COmponents and Rationales for Effectiveness Fidelity Method and the team's prior work to identify themes. RESULTS:We achieved saturation after 22 interviews with 24 participants (16 U.S. participants, 8 Canadian). We identified four themes: 1) Traditionally, literacy promotion focused on enhancing preliteracy skills and school readiness. Over time, this outcome has evolved to include fostering early relational health as a foundational goal; 2) Core components include a trusted clinician delivering a strength-based, family-centered message, while modeling developmentally-informed shared reading; 3) Components that are adaptable to setting and context include literacy-rich clinical environments and community resource referrals; 4) Experts diverged on whether providing a children's book during literacy promotion is essential, but there was congruence that book provision alone is insufficient. CONCLUSION/CONCLUSIONS:Experts identified strength-based, family-centered guidance from a trusted clinician with developmentally-focused modeling as core to support intended outcomes of early relational health and school readiness. This understanding can inform training and healthcare improvement activities aimed at optimizing primary care-based literacy promotion.

INTRODUCTION/BACKGROUND:Identifying strategies to mitigate the effects of secondhand smoke exposure is crucial for public health. Thus, we estimated the effect of a 2018 federal smoke-free housing (SFH) policy on adverse birth outcomes among New York City (NYC) public-housing residents. METHODS:We obtained data on all live births to NYC residents in NYC from 2013 to 2022, using the borough-block-lot of the birthing person's address to identify births to public-housing residents. We then estimated the effect of the SFH policy on risk of preterm birth or low birth weight among births to NYC public-housing residents using a linear-probability difference-in-differences estimator, weighted by inverse probability weights to increase the plausibility of the parallel-trends assumption. RESULTS:Our sample included 44 455 births to public-housing residents and 803 648 births to non-public-housing residents. Difference-in-difference analyses suggested the SFH policy did not affect risk of preterm birth (risk difference (RD) per 100: 0.1; 95% CI -0.6 to 0.9) or low birth weight (RD per 100: 0.3, 95% CI -0.4 to 1.0). Event-study analyses supported these findings and lent credibility to the parallel-trends assumption. CONCLUSIONS:We estimated no initial effects of a federal SFH policy on risk of preterm birth or low birth weight among births to NYC public-housing residents.

INTRODUCTION/BACKGROUND:Effective July 2018, the U.S. Department of Housing and Urban Development issued a rule requiring all public housing authorities to implement smoke-free housing (SFH) policies in their developments. We examined the differential impacts of SFH policy on hospitalizations for myocardial infarction (MI) and stroke among adults aged ≥50 years old living in New York City (NYC) Housing Authority (NYCHA) versus a matched-comparison population in NYC. AIMS AND METHODS/OBJECTIVE:We identified census block groups (CBGs) comprised solely of 100% NYCHA units (N = 160) and compared NYCHA CBGs to a selected subset of CBGs from all CBGs with no NYCHA units (N = 5646). We employed propensity score matching on distributions of key CBG-level sociodemographic and housing covariates. We constructed incident rates per 1000 persons by aggregating 3-month "quarterly" counts of New York State all-payer hospitalization data from October 2015 to December 2022 and dividing by the population aged ≥50 in selected CBGs, ascertained from 2016 American Community Survey 5-year estimates. We selected a difference-in-differences (DID) analytic approach to examine pre- and post-policy differences in incident hospitalizations between the intervention and matched-comparison groups. RESULTS:Matching results indicated a balanced match for all covariates, with standardized mean differences <0.10. In DID analyses, we observed small declines in both MI (DID = -0.26, p = .02) and stroke (DID = -0.28, p = .06) hospitalization rates for NYCHA CBGs compared to non-NYCHA CBGs from pre-to post-54 months' policy. CONCLUSIONS:SFH policies in NYC were associated with small reductions in CVD-related hospitalizations among older adults living in housing subject to the policy. IMPLICATIONS/CONCLUSIONS:Housing remains a key focal setting for interventions to reduce SHS exposure and associated morbidities. Ongoing monitoring is warranted to understand the long-term impacts of SFH policies in public housing developments.

OBJECTIVES/OBJECTIVE:To assess the acceptability of an infection-control prevention strategy during the COVID-19 pandemic for skilled nursing facilities (SNFs) staff and residents, to describe implementation challenges and potential solutions, and to explore intervention impact perceptions. DESIGN/METHODS:Qualitative investigation of a multimethod pragmatic clinical trial designed to develop and test a novel cohorting intervention to mitigate infection transmission in SNFs during the COVID-19 pandemic. SETTING AND PARTICIPANTS/METHODS:We used a purposive sample of staff and residents in 2 New York City nonprofit SNFs participating in the intervention trial. METHODS:We developed a novel cohorting strategy to minimize infection transmission by using infection risk (vaccination or prior infection history) to assign staff to specific residents. We employed a qualitative descriptive approach using content thematic analysis of semistructured interviews with staff and residents to identify themes of acceptability, challenges, and potential impact. RESULTS:Seventy-one staff and 16 residents completed semistructured interviews. Staff and residents supported the intervention. However, both identified challenges, including concerns that switching assignments could lead to staffing issues and care discontinuity. Staff identified communication about the intervention as both a challenge and potential solution, citing a desire for clear and consistent communication across all employees. Staff felt the intervention had potential impact in reducing infection risk fear, promoting effective protective equipment usage, and encouraging more interaction and less isolation than standard prevention practices. CONCLUSIONS AND IMPLICATIONS/CONCLUSIONS:We developed a novel and acceptable preventive strategy that may increase residents' flexibility and reduce their isolation as well as staff stress. Clear, consistent, and proactive communication may improve intervention acceptability and perceptions about impact. Similar infection-control protocols might be adapted for different long-term care infection risks. Communication at all staffing levels and with residents is essential to ensure the intervention is acceptable to both. Future trials could include social isolation and staff burnout as potential outcomes.

BACKGROUND:The Korean government and experts initiated a national trauma system development project in 2012. Its first major initiative was establishing and operating regional trauma centers across the country. We assessed whether the severity-adjusted mortality rates were lower in trauma centers compared with non-trauma centers and the specific benefits of trauma centers for patients with trauma. METHODS:This retrospective cohort study analyzed the data of patients with trauma registered in the National Emergency Department Information System from 2015 to 2019. Additionally, we used the Korean Trauma Data Bank and trauma center status data provided by the Ministry of Health and Welfare. We focused on patients with survival probabilities of < 0.5 according to the International Classification of Diseases Injury Severity Score, 9th Edition. The severity-adjusted mortality rates between the trauma centers and non-trauma centers were compared. RESULTS:The 7 qualified trauma centers had notably more younger patients with penetrating injuries than the non-trauma centers. Patients admitted to the trauma centers had more critical vital signs and a higher incidence of reduced consciousness than those admitted to the non-trauma centers. After adjusting for severity, the in-hospital mortality rates were significantly lower in the trauma centers than in the non-trauma centers (16.9% vs. 18.2%; relative risk, 0.933; 95% confidence interval, 0.874-0.997). Patients in shock conditions had significantly lower mortality rates when treated in trauma centers. The disparity in cumulative mortality rates between the trauma centers and non-trauma centers was most pronounced 2 days post-admission. CONCLUSION/CONCLUSIONS:This study confirmed that the national project for establishing regional trauma centers effectively reduced mortality rates among severely injured patients.

Per-and polyfluoroalkyl substances (PFAS) are a pervasive family of synthetic compounds with a wide range of reported health effects. Epigenetic clocks, DNA methylation-based predictors of chronological and biological age, are promising biomarkers for characterizing biological aging in humans. The potential impact of PFAS exposure on epigenetic aging in the general US population remains unclear. In the 1999-2000 National Health and Nutrition Examination Survey (NHANES) cycle (N = 262), eleven PFASs were measured in serum and DNA methylation was measured in blood with the EPICv1 array. Seven epigenetic clocks and their respective epigenetic age acceleration (EAA) measures were calculated. Survey-design weighted generalized linear regression models were used to test adjusted associations between individual log₂-transformed PFAS concentrations and EAA stratified by sex. Among male participants, doubling of PFNA concentrations was associated with greater EAA across several clocks including the Horvath clock (beta = 1.48, 95 % CI: 0.35, 2.61), Skin&Blood clock (beta = 1.27, 95 % CI: 0.21, 2.32), and PhenoAge (beta = 1.43, 95 % CI: 0.41, 2.44), and doubling of PFOS exposure was associated with greater Skin&Blood EAA (beta = 1.14, 95 % CI: 0.04, 2.24). When considering cell-adjusted EAA measures, each of these associations among male participants remained significant, and PFOSA was associated with decreased PhenoAge EAA (beta = -0.84, 95 % CI: -1.49, -0.18) and GrimAge2 EAA (beta = -0.81, 95 % CI: -1.51, -0.11) among female participants. In summary, we found evidence of sex-specific associations between PFAS exposure and epigenetic aging in a sample of older adults representative of the general US population.
