Relationship Between Primary Care Physician Capacity and Usual Source of Care.

Background: The NASEM Primary Care Report and Primary Care scorecard highlighted the importance of primary care physician (PCP) capacity and having a usual source of care (USC). However, research has found that PCP capacity and USC do not always correlate. This exploratory study compares geographic patterns and the characteristics of counties with similar rates of PCP capacity but varying rates of USC.

A comparison of social prescribing approaches across twelve high-income countries.

Background: Social prescribing connects patients with community resources to improve their health and well-being. It is gaining momentum globally due to its potential for addressing non-medical causes of illness while building on existing resources and enhancing overall health at a relatively low cost. The COVID-19 pandemic further underscored the need for policy interventions to address health-related social issues such as loneliness and isolation.

Prevalence and Correlates of Unmet Medical and Social Needs in Virginia's Medicaid Managed Long Term Services and Supports Program.

Background: Medicaid Long Term Services and Support (LTSS) programs serve individuals with complex medical and social needs. Increasingly, state Medicaid programs are contracting with managed care organizations to administer LTSS programs.

Objectives: Understand the prevalence of and risk factors for unmet medical and social needs among a sample of patients within a Medicaid managed LTSS program.

Postpartum medication for opioid use disorder outcomes associated with prenatal treatment and neighborhood-level social determinants.

Background: Opioid use disorder is a leading cause of death through the year postpartum.

Objective: This study aimed to identify the association of neighborhood-level social determinants of health and prenatal opioid use disorder treatment receipt with the outcomes of medication treatment for opioid use disorder through the year postpartum among a cohort of birthing people.

Study Design: This was a population-based retrospective cohort study that used state Medicaid claims and enrollment data for the 1690 individuals who delivered a live infant between July 1, 2016 and December 31, 2020 and received medication for opioid use disorder at delivery.

Assessment of COVID-19-Driven Changes in an Integrated OBGYN-Addiction Treatment Clinic and Future Implications.

Objective: The COVID-19 pandemic prompted healthcare delivery changes, but the associated impacts on substance use disorder treatment outcomes among pregnant and parenting people are unknown. This study aims to (1) describe COVID-19-driven clinical practice changes, (2) evaluate clinic-level visit attendance patterns, and (3) compare patient-level treatment engagement outcomes across 3 COVID-19 pandemic phases in an OBGYN-addiction treatment clinic.

Methods: COVID-19 phases include pre-COVID-19 (August 2019-February 2020), early COVID-19 (March-December 2020), and COVID-19 vaccine (January-July 2021).

Incarceration status at buprenorphine initiation and OUD treatment outcomes during pregnancy.

Introduction: Opioid use disorder (OUD) is a leading cause of pregnancy-associated deaths. OUD treatment with buprenorphine (BUP) reduces overdose risk and improves perinatal outcomes. Incarceration can be a barrier to receipt of OUD treatment during pregnancy and postpartum.

Disparities in opioid use disorder-related hospital use among postpartum Virginia Medicaid members.

Introduction: The overdose crisis is increasingly revealing disparities in opioid use disorder (OUD) outcomes by race and ethnicity. Virginia, like other states, has witnessed drastic increases in overdose deaths. However, research has not described how the overdose crisis has impacted pregnant and postpartum Virginians.

Psychiatric comorbidities and their treatment predict buprenorphine continuation among postpartum people with opioid use disorder.

Background: Opioid use disorder (OUD) is a growing crisis among pregnant and postpartum people. Psychiatric comorbidities are common, yet how they impact OUD treatment outcomes is not well characterized. The aim of this study was to assess the association of psychiatric comorbidities and receipt of psychiatric treatment with buprenorphine continuation through one year postpartum among a sample of people with OUD.

Patient Preferences for Discussing and Acting on Health-Related Needs in Primary Care.

Background: Addressing social needs, health behaviors, and mental health may help patients more than traditional medical care. However, these root causes of poor health are difficult to address and the role of primary care is unclear. This qualitative study assesses patient's willingness and motivations to discuss and accept assistance for these needs from their primary care team.

Virginia Medicaid Expansion: New Members Report Reduced Financial Concerns During The COVID-19 Pandemic.

Medicaid is a critical antipoverty program. Since the Affordable Care Act expanded Medicaid eligibility, millions of newly eligible people have enrolled, creating positive financial improvements for low-income families. We examined the association of Virginia's 2019 Medicaid expansion and changes in health care-related and non-health-care-related financial needs among newly eligible Medicaid enrollees.

Exploring the Relationship Between Community Program Location and Community Needs.

Introduction: Health behaviors, mental health, and social needs impact health, but addressing these needs is difficult. Clinicians can partner with community programs to provide patients support. The relationship between program location and community need is uncertain.

Stakeholder input on a care planning tool to address unhealthy behaviors, mental health needs, and social risks: The value of different stakeholder perspectives.

This report describes how stakeholder groups informed a web-based care planning tool's development for addressing root causes of poor health. Stakeholders included community members (n = 6), researchers (n = 6), community care providers (n = 9), and patients (n = 17). Feedback was solicited through focus groups, semi-structured interviews, and user experience observations and then qualitatively analyzed to identify themes.

Neuronal integrity and complement control synaptic material clearance by microglia after CNS injury.

Phagocytosis of synaptic material by microglia is critical for central nervous system development. Less well understood is this microglial function in the injured adult brain. Assay of microglial phagocytosis is challenging, because peripheral myeloid cells engraft the site of injury, which could obscure interpretation of microglial roles.
