Health Policy & Population Health Research
OHSU's Department of Family Medicine studies access to health care, disparities in care, and how changes in health policy impact population health, using electronic health records (EHR), insurance claims, and state databases. Several projects study primary care utilization by uninsured and underinsured populations, particularly relating to the Affordable Care Act. Research findings inform community, practice and policy interventions that improve the delivery of care for vulnerable populations and reduce health disparities.
Health Policy & Population Health Research
Principal Investigator: Jen
DeVoe, MD, DPhil
Our goal is to test the hypothesis that gaining public
insurance coverage is associated with higher rates of receipt of CVD primary
and secondary preventive care among individuals with a usual and continuous
source of primary care. The project will also demonstrate the value of
using a unique safety net clinic EHR database in research to evaluate the
impact of practice and policy interventions on vulnerable populations, with
potential for widespread replication.
Principal Investigator: Jen

The project seeks to (i) incentivize providing value over volume of
visits, (ii) support comprehensive treatment modalities for patients with
complex needs, and (iii) allow CHCs to focus more of their resources on
population health initiatives.
The Primary Care Medical Home & Preventive Service Use in Latino Immigrants
Principal Investigator: John Heintzman, MD, MPHThis project
studies how certain features of the Primary Care Medical Home (PCMH) impact the
utilization of recommended preventive health services by Latino Immigrants. The
study expands on existing PCMH research, and uses the OCHIN Electronic Health
Record (EHR) data to evaluate the association between certain PCMH principles
and preventive service use in Latino immigrants.
Principal Investigator: Jen
DeVoe, MD, DPhil
The project is one of the first to examine changes in access
to and receipt of healthcare services and to Medicaid expenditures following
ACA Medicaid expansions among a large population of safety net clinic
patients. This project builds on our previous work that developed a
robust community-based research infrastructure within the OCHIN community
health information network of community health centers. The project capitalizes on our unique
partnership with OCHIN and our experience conducting health services research
and assessing natural policy experiments.

This project will foster an understanding of how Medicaid
expansion impacts Diabetes Memellitus (DM) prevention, treatment, expenditures,
and health outcomes. Detailed information on changes in health insurance,
service receipt, and health outcomes, with data spanning 9 years (pre- and
post-expansion), are collected that compare states that expanded Medicaid, and
those that did not.

This OHA study conducts qualitative research to generate
formative, iterative, rapid feedback on the performance of the Transformation
Center and its progress in supporting and spreading health system
transformation in Oregon.
Principal Investigator: John
Muench, MD
This mixed methods study is designed to foster understanding of such
disparities by examining preventive services provided to people in two systems
of care—one a large integrated health plan, and the second, a consortium of
Federally Qualified Health Centers (FQHCs) participating in a common health
information network. The goal is to identify modifiable factors that affect
preventive service uptake among individuals with serious mental illnesses.
