Background: Given that individuals with substance use disorders (SUDs) have a variety of needs beyond substance use, it is critical to examine the comprehensiveness of services offered within outpatient SUD treatment facilities, where many individuals with SUDs receive care. This study's objective is to develop clusters of services offered, and assess organizational, policy, and environmental characteristics associated with having a more comprehensive treatment model.

Methods: We conducted a principal component analysis (PCA) using data on SUD treatment facilities (n=8, 197) from the 2022 Mental Health and Addiction Treatment Tracking Repository, a national database of SUD treatment facilities.

Background: The effectiveness of hospital-based transitional opioid programs (TOPs), which aim to connect patients with substance use disorders (SUD) to ongoing treatment in the community following initiation of medication for opioid use disorder (MOUD) treatment in the hospital, hinges on successful patient transitions. These transitions are enabled by strong partnerships between hospitals and community-based organizations (CBOs). However, no prior study has specifically examined barriers and facilitators to establishing SUD care transition partnerships between hospitals and CBOs.

Introduction: Despite being an important determinant of health outcomes, measures of structural racism are lacking in studies examining the relationship between the social determinants of health (SDOH) and overdose deaths. The aim of this study is to examine the association between per capita revenue generated from fines and forfeitures, a novel measure of structural racism, and other SDOH with county-level overdose deaths from 2017-2020.

Methods: This longitudinal analysis of 2,846 counties from 2017-2020 used bivariate and multivariate Generalized Estimating Equations models to estimate associations between county overdose mortality rates and SDOH characteristics, including the fines and forfeitures measure.

  • In 2016, the Centers for Medicare and Medicaid Services encouraged the tracking of social health factors using ICD-10 Z-codes to better understand patients' health-related social needs.
  • A study from 2017 to 2021 found that while a majority of hospitals documented at least one Z-code related to social determinants of health, overall adoption rates were low, especially outside of housing needs.
  • Factors like being part of a teaching hospital or larger health system were linked to higher use of Z-codes, indicating a need for improved training and consistency in using these coding methods.

Telehealth utilization increased during the COVID-19 pandemic, yet few studies have documented associations of telehealth use with subsequent medical costs and health care utilization. We examined associations of telehealth use during the early COVID-19 public health emergency (March-June 2020) with subsequent total medical costs and health care utilization among people with heart disease (HD). We created a longitudinal cohort of individuals with HD using MarketScan Commercial Claims data (2018-2022).

Introduction: Hospitals are an ideal setting to stage opioid-related interventions with patients who are hospitalized due to overdose or other substance use-related complications. Transitional opioid programs-which initiate care and provide linkages upon discharge, such as screening, initiation of medications for opioid use disorder, and addiction consult services-have become the gold standard, but implementation has been uneven. The purpose of this study was to assess disparities in the availability of hospital-based transitional opioid programs, across rural and urban hospital settings in the United States.

Background: Hospitals are a key touchpoint to reach patients with substance use disorders (SUDs) and link them with ongoing community-based services. Although there are many acute care interventions to initiate SUD treatment in hospital settings, less is known about what services are offered to transition patients to ongoing care after discharge. In this study, we explore what SUD care transition strategies are offered across nonprofit US hospitals.

Article Synopsis
  • Cardiovascular disease is the top global cause of health issues and deaths, with social factors significantly affecting these health outcomes.
  • A review of existing research highlighted 50 studies that commonly used data from electronic health records, national surveys, and census information to address healthcare access and neighborhood risk factors.
  • Most interventions focused on improving healthcare access rather than addressing broader social determinants like economic stability and education, indicating that there is still untapped potential in using this data to reduce cardiovascular disease burden.

Background: Acute-care interventions that identify patients with substance use disorders (SUDs), initiate treatment, and link patients to community-based services, have proliferated in recent years. Yet, much is unknown about the specific strategies being used to support continuity of care from emergency department (ED) or inpatient hospital settings to community-based SUD treatment. In this scoping review, we synthesize the existing literature on patient transition interventions, and form an initial typology of reported strategies.

While rural-urban disparities in health and health outcomes have been demonstrated, because of their impact on (and intervenability to improve) health and health outcomes, we sought to examine cross-sectional and longitudinal inequities in health, clinical care, health behaviors, and social determinants of health (SDOH) between rural and non-rural counties in the pre-pandemic era (2015 to 2019), and to present a Health Equity Dashboard that can be used by policymakers and researchers to facilitate examining such disparities. Therefore, using data obtained from 2015-2022 County Health Rankings datasets, we used analysis of variance to examine differences in 33 county level attributes between rural and non-rural counties, calculated the change in values for each measure between 2015 and 2019, determined whether rural-urban disparities had widened, and used those data to create a Health Equity Dashboard that displays county-level individual measures or compilations of them. We followed STROBE guidelines in writing the manuscript.

Background: Evidence suggests that harm reduction, a public health strategy aimed at reducing the negative consequences of a risky health behavior without requiring elimination of the behavior itself, may be a promising approach for minimizing drug-related harms while engaging individuals with substance use disorders (SUDs) in care. However, philosophical clashes between the medical and harm reduction models may pose barriers to adopting harm reduction approaches within medical settings.

Objective: To identify barriers and facilitators to implementing a harm reduction approach toward care within healthcare settings.
