About UsEstablished in 2013, the Health Workforce Research Center (HWRC) on Emerging Health Workforce Topics, is part of the Fitzhugh Mullan Institute for Health Workforce Equity. The center’s research portfolio examines how new payment and delivery models, patient centered medical homes, team-based care, telehealth, National Health Service Corps, and other emerging care management strategies impact access and quality of care for rural and underserved populations.
We are committed to advancing the science of workforce analysis by 1) developing cutting edge research methods for documenting how workforce staffing configurations impact patient satisfaction and health outcomes, 2) employing innovative uses of available datasets to identify the workforce caring for patients living in health professional shortage areas, 3) publishing a portfolio of peer-reviewed publications that build off of each other to identify policies for improving care for vulnerable and underserved populations, and 4) training the next generation of health workforce researchers to carry the work forward into the future. |

Current Research Studies (2022-2023)
Diversity at an organizational level may have several benefits, including improved provider cultural sensitivity and cultural competency. This study assesses the organizational (i.e., practice-level) diversity of primary care physicians (PCPs) that care for Medicaid patients using a unique score of practice diversity.
Key Questions:
For questions about this study, contact Anushree Vichare at avichare@gwu.edu.
Key Questions:
- What is the overall racial and ethnic diversity of the primary care physician workforce that cares for Medicaid patients?
- What is the average diversity of a practice’s physician workforce relative to the diversity of its patient panel among practices that serve Medicaid patients?
- How does the diversity score compare across provider settings, e.g., CHCs and other primary care practices, and by practice integration?
For questions about this study, contact Anushree Vichare at avichare@gwu.edu.
This study will examine how variations in state Medicaid policies are associated with participation by community health workers (CHWs) in Medicaid billing and the breadth and volume of CHWs services billed by Community Health Centers compared to other settings.
Key Questions:
For questions about this study, contact Clese Erikson at cerikson@gwu.edu.
Key Questions:
- What is the level and distribution by state of CHW participation in Medicaid, and what are their practice patterns – e.g., geographic locations, types and volume of services provided, and the demographics of patients served?
- Are CHCs more likely to bill for CHW services than other primary care settings in a state that allow billing? How do the volume and breadth of services compare?
- Are different types of state Medicaid policies associated with participation and the level of service provided by CHWs in Medicaid?

Poor access to prenatal care is a key driver of high maternal mortality and morbidity in the U.S., and telehealth could help enhance prenatal care. This study will examine the uptake of telehealth use for prenatal care among disadvantaged pregnant people during the COVID-19 pandemic and explore its potential for improving access and maternal health outcomes.
Key Questions:
For questions about this study, contact Anushree Vichare at avichare@gwu.edu.
Key Questions:
- How was telehealth used for prenatal care at the start, during, and latter periods of the COVID-19 pandemic?
- What types of prenatal services were delivered via telehealth? What types of telehealth services (audio/digital) were utilized?
- What patient and provider characteristics were associated with telehealth use for prenatal care? What was the uptake among those with high-risk pregnancies?
- Did telehealth utilization for prenatal care differ among the general population and disadvantaged groups, such as those living in rural areas and seeking care in CHCs?
For questions about this study, contact Anushree Vichare at avichare@gwu.edu.
This research study will use Medicare Provider Enrollment, Chain, and Ownership System (PECOS) data matched with other workforce data to examine the movement of healthcare providers across organizations during different stages of the pandemic. The findings will inform policy efforts to anticipate and model the flow of providers to provide more coherent responses to shocks to the health care system.
Key Questions:
For questions about this study, contact Stephen Petterson at spetterson72@gwu.edu.
Key Questions:
- How has the COVID-19 pandemic impacted provider turnover at different stages, including switching the job and attrition from practice?
- What was this impact across different practices and organizations—by size, specialty composition, hospital or office-based?
- What were the differences in mobility by provider characteristics, including provider type, gender, and race/ethnicity of physicians?
For questions about this study, contact Stephen Petterson at spetterson72@gwu.edu.
This study will assess the degree of vertical integration among federally funded community health centers (CHCs) and the resulting variation in workforce configuration. In year two, if selected, we propose to build on this landscape to analyze the impact of vertical integration on CHC productivity and access to care for patients.
Key Questions:
For questions about this study, contact Eric Luo at qluo@gwu.edu.
Key Questions:
- What are the different vertical integration structures between CHCs and hospitals and health systems?
- How many CHCs are now vertically integrated?
- What is the trend of vertical integration among CHCs?
- What is the impact of vertical integration on the workforce configuration of CHCs?
For questions about this study, contact Eric Luo at qluo@gwu.edu.
This study will examine the effects of substituting staff nurses with travel nurses on patient safety in different types of hospital units before and during the COVID-19 pandemic. Using Premier Inc. data from 2019 through the end of 2022, we will identify the minimum and maximum marginal effect of travel nurses’ productivity, beyond which additional travel nurses have a negative impact on patient safety and quality.
Key Question:
For questions about this study, contact Patricia Pittman at ppittmano@gwu.edu.
Key Question:
- What is the marginal effect of travel nurses, as a proportion of total nurse staff, on patient outcomes by type of hospital unit?
