Welcome to the Ryskina Lab!

We are part of the Division of General Internal Medicine in the Department of Medicine at the Perelman School of Medicine at the University of Pennsylvania. Our research space and offices are in Blockley Hall, 423 Guardian Drive.

Our research aims to understand variations in the quality of physician services to improve health outcomes for older adults with multiple chronic conditions.  We have examined several domains of physician care quality in primary care, hospitals, and nursing homes: timeliness, effectiveness, patient-centeredness, equity, and efficiency. Our current ongoing work focuses on evaluating the role of physician specialization in nursing home practice in healthcare utilization and functional outcomes of older adults. To do so, we have collected a rich database of clinical, demographic, and socioeconomic information for a large cohort of patients that received post-acute care in US skilled nursing facilities between 2012 and 2019. Other projects on our research agenda implement complex linkages of surveys, claims, and other secondary datasets, to examine aspects of physician practice, care quality, and costs in general internal medicine.
