Background: With rapid acceleration of Veterans’ use of care in the community, limited data exist to prepare community providers and others in the broader VA integrated care network. Many community providers and health plans may assume Veteran patients are similar to their routine practice populations, composed primarily of civilians, although prior research would suggest otherwise. Significance/Impact: The proposed study will use detailed, current, and comprehensive data from the Behavioral Risk Factor Surveillance System (BRFSS), National Health Interview Survey (NHIS), the National Surveys on Drug Use and Health (NSDUH), and VA Corporate Data Warehouse (CDW) to quantify broadly the distribution of health and healthcare factors for Veterans, VA users, and VA non-users and to evaluate in-depth the factors that differ between Veterans and civilians. This information will not only substantially update our knowledge of how Veterans are similar to or different from civilians but will also be used by VA policymakers to improve the design and readiness of community care partners as VA referrals increase. Innovation: In contrast to previous studies and reports using national survey data, the proposed project will include VA data to provide a richer description of VA patients than is possible using only publicly-available data on VA users, and examine in depth the patterns in Veterans’ health and healthcare across subgroups and over time. The proposed research has no corollary or antecedent study in VA HSR&D’s or QUERI’s portfolio, and of the studies funded outside the VA that use one or more of these sources and is underway or recently completed, none proposed to use VA data or to combine the breadth and depth of the proposed project Specific Aims: This project aims to 1. Quantify the distribution of population characteristics, health behaviors, health conditions, health status, access to care, and healthcare utilization among Veterans overall and among VA users and non-users; 2. Evaluate the extent to which patterns in population-, health-, and healthcare- related factors differ between Veterans and civilians; 3. Determine whether the patterns identified under Aims 1 and 2 vary for subgroups defined by age, gender, and race-ethnicity; and, 4. Conduct an expert panel to review results from Aims 1-3 to come to consensus on evidence-based recommendations for improved community care (e.g., community provider readiness) and health equity. Methodology: We will conduct a secondary analysis using multiple years of data from BRFSS, NHIS, NSDUH, and VA CDW. Our analyses will include measures for Veteran and VA user status, geographic region, population characteristics, health behaviors and conditions, and healthcare outcomes, such as access, utilization, and unmet need for care. We will quantify the distribution of population-, health-, and healthcare- related factors among Veterans, VA users, and VA non-users, evaluate how these factors differ between Veterans...
