• The Patient Driven Payment Model, Skilled Nursing Facility Coding Intensity, and Medicare Expenditures

  JAMA Internal Medicine · 2025-07-21 · 4 citations

  articleOpen access

  Importance: The Patient Driven Payment Model (PDPM), implemented in October 2019, fundamentally changed how Medicare reimburses skilled nursing facilities (SNFs) for postacute care, shifting from therapy volume-based payment to reimbursement based on patient clinical and functional characteristics. Understanding the relationship of the PDPM to SNF coding practices, Medicare expenditures, and clinical outcomes is essential for evaluating its policy and clinical implications. Objective: To evaluat…

• Do targeted intergovernmental fiscal transfers improve health outcomes? Evidence from Kenyan decentralization using the difference-in-differences technique

  Health Research Policy and Systems · 2024-12-20 · 2 citations

  articleOpen access

  BACKGROUND: As envisioned by the 2010 Constitution, Kenya implemented a devolved system of government in March 2013, setting up 47 counties and a corresponding number of local governments. These counties differed in their levels of development. While counties such as Nairobi and Kiambu led in social and economic indicators, others such as Turkana, Mandera and Wajir were at the bottom of the list. Keeping the between-country disparities and the need to remedy those disparities in mind, the nation…

• Immigrant Staff in Nursing Homes: Mitigating Staffing Shortages During the COVID-19 Pandemic

  Medical Care Research and Review · 2025-06-29 · 1 citations

  article

  The COVID-19 pandemic exacerbated staffing shortages in U.S. nursing homes. Staff who are immigrants may have stronger tendencies to remain in their jobs than U.S.-born staff, but evidence is lacking. In this study, we predicted the share of immigrant staff and used a difference-in-differences regression to investigate whether nursing homes with a higher vs. lower proportion of immigrant certified nursing assistants (CNAs) experienced lesser declines in staff hours per resident day (HPRD) during…
