Risk for Acute Care Utilization in Housing-Insecure Adults
BACKGROUND: To identify patients at the highest risk for acute care utilization, health care systems have developed "hot spotter" programs. Homelessness is a robust social determinant of acute care utilization. OBJECTIVES: To describe the prevalence, patterns, and correlates of meeting criteria for a hot spotter program among housing-insecure adults in the US Veterans Health Administration (VHA). RESEARCH DESIGN: Among veterans on the VHA Homeles…
Effects of Veterans Affairs Access Expansions on Inpatient Care for Women Veterans
Background: Enactment of the Veterans Choice Act (VCA) in 2014 and expansion of Medicaid programs led to greater options for Veterans to receive health care outside of the U.S. Department of Veterans Affairs (VA). However, little is known about how much care women Veterans receive in VA or non-VA settings paid by VA or other insurance types. We explore trends in inpatient care received by women Veterans before and after implementation of the VCA,…
Spending by the Veterans Affairs Health Care System for Medicare Advantage Enrollees
This cohort study estimates US Department of Veterans Affairs (VA) spending for veterans dually enrolled in the VA health care system and Medicare Advantage from 2019 to 2023
Impact of VA’s Clinical Resource Hub Primary Care Telehealth Program on Health Care Use and Costs
BACKGROUND: Telehealth can improve health care access in underserved areas. Hub-and-spoke-models, wherein providers in regional hubs deliver care through telehealth to patients visiting local "spoke" clinics, can improve access. However, cost impacts of this model are unknown. OBJECTIVE: Evaluate the utilization and cost impacts of VA's Clinical Resource Hub program for primary care (CRH-PC), a hub-and-spoke-model. DESIGN: Adjusted difference-in-…
Differences in use of Veterans Health Administration and non‐Veterans Health Administration hospitals by rural and urban Veterans after access expansions
PURPOSE: To examine changes in rural and urban Veterans' utilization of acute inpatient care in Veterans Health Administration (VHA) and non-VHA hospitals following access expansion from the Veterans Choice Act, which expanded eligibility for VHA-paid community hospitalization. METHODS: Using repeated cross-sectional data of VHA enrollees' hospitalizations in 9 states (AZ, CA, CT, FL, LA, MA, NY, PA, and SC) between 2012 and 2017, we compared rur…
Reexamining Differences Between Black and White Veterans in Hospital Mortality and Other Outcomes in Veterans Affairs and Other Hospitals
OBJECTIVES: To examine Black-White patient differences in mortality and other hospital outcomes among Veterans treated in Veterans Affairs (VA) and non-VA hospitals. BACKGROUND: Lower hospital mortality has been documented in older Black patients relative to White patients, yet the mechanisms have not been determined. Comparing other hospital outcomes and multiple hospital systems may help inform the reasons for these differences. METHODS: Repeat…
Rural and urban differences in the implementation of Virtual Integrated Patient‐Aligned Care Teams
PURPOSE: Workforce shortages contribute to geographic disparities in accessing primary care services. An innovative, clinic-to-clinic videoconferencing telehealth program in the Veterans Health Administration (VHA) called the Virtual Integrated Patient-Aligned Care Teams (V-IMPACT) was designed to increase veterans' access to primary care and relieve workforce shortages in VA primary care clinics, including in many rural areas. This paper describ…
Health Care Access Expansions and Use of Veterans Affairs and Other Hospitals by Veterans
This cohort study examines changes in the use of Veterans Affairs (VA) and non-VA hospitals by VA enrollees and mortality associated with these policies
Use of the Veterans’ Choice Program and Attrition From Veterans Health Administration Primary Care
BACKGROUND: Concerns over timely access and waiting times for appointments in the Veterans Health Administration (VHA) spurred the push towards greater privatization. In 2014, VHA increased the provision of care from community providers through the Veterans' Choice Program (Choice). OBJECTIVES: We examined the characteristics of patients and practices more likely to use Choice care and whether using Choice care affected patients' attrition from V…
Veterans’ Reliance on VA Care by Type of Service and Distance to VA for Nonelderly VA-Medicaid Dual Enrollees
BACKGROUND: Not much is known about nonelderly veterans and their reliance on care from the Veterans Affairs (VA) health care system when they have access to non-VA care. OBJECTIVES: To estimate VA reliance for nonelderly veterans enrolled in VA and Medicaid. RESEARCH DESIGN: Retrospective, longitudinal analysis of Medicaid claims data and VA administrative data to compare patients' utilization of VA and Medicaid services 12 months before and for…
High Quality of Care Persists With Shifting Depression Services From VA Specialty to Integrated Primary Care
BACKGROUND/OBJECTIVE: Offering depression collaborative care services in primary care (PC) settings can reduce use of nonintegrated mental health care resources and improve mental health care access, particularly for vulnerable PC patients. Tests of effects on depression care quality, however, are needed. We examined overall quality of depression care and tested whether increasing clinic engagement in Veterans Affairs (VA)'s Primary Care-Mental H…
Impact of Medical Home Implementation Through Evidence-based Quality Improvement on Utilization and Costs
BACKGROUND: Evidence-based quality improvement (EBQI) methods may facilitate practice redesign for more effective implementation of the patient-centered medical home (PCMH). OBJECTIVE: We assessed changes in health care utilization and costs for patients receiving care from practices using an EBQI approach to implement PCMH and comparison practices over a 5-year period. RESEARCH DESIGN: We used longitudinal, electronic data from patients in 6 pra…
Costs Associated With Multimorbidity Among VA Patients
BACKGROUND: Multimorbidity (the presence of multiple chronic conditions) is associated with high levels of healthcare utilization and associated costs. We investigated the association between number of chronic conditions and costs of care for nonelderly and elderly Veterans Affairs (VA) patients, and estimated mean VA healthcare costs for the most prevalent and most costly combinations of 3 conditions (triads). METHODS: We identified a cohort of …
Trends in Rates and Attributable Costs of Conditions among Female VA Patients, 2000 and 2008
Reducing Costs of Acute Care for Ambulatory Care-sensitive Medical Conditions
BACKGROUND: New patient-centered models of ambulatory care aim to substitute better primary care for preventable acute care within existing primary care practices. This study aims to identify whether mental illness and other characteristics of primary care patients are related to risk for an acute event for an ambulatory care-sensitive condition (ACSC). METHODS: We conducted a 2-year, longitudinal analysis comparing ambulatory care-sensitive admi…
The Role of Federally Funded Health Centers in Serving the Rural Population
Context: Federally funded health centers attempt to improve rural health by reducing and eliminating access barriers to primary care services. Purpose: This study compares rural health center patients with people in the general rural population for indicators of access to preventive services and health outcomes. Methods: Data from the annual reporting system for federally funded health centers, the 1999 Uniform Data System, and published national…
