PENNY HOLLANDER FELDMAN, PhD, is Senior Research Scientist and Director Emerita at the VNSNY Center for Home Care Policy & Research. Dr. Feldman served as Center Director from 1993–2014 and as VNSNY Senior Vice President, Research and Evaluation, from 2009-2014. In her current position, she leads research focused on improving the quality, outcomes, and cost-effectiveness of home-based care for an aging and racially diverse population characterized by functional impairment, multiple co-morbidities, and complex care needs. She is the principal investigator of several grants testing home-based interventions for individuals facing the challenges of uncontrolled hypertension, post-stroke limitations, and chronic illness, compounded by socio-economic, racial, and linguistic barriers to effective self-care management. She is also co-investigator on several comparative effectiveness studies designed to assess the impact of early home nursing visits and early physician follow-up on selected patient populations.

While Director of the Center, Dr. Feldman established a robust research enterprise with rigorously trained methodological staff and state-of-the-art informatics capacity to address two goals: 1) support quality of care, quality improvement and program planning at VNSNY, and 2) maintain a portfolio of externally funded research to advance the home care knowledge base worldwide. Among other projects, Dr. Feldman served as principal investigator on a series of comparative effectiveness grants funded by AHRQ and NHLBI—most of them focused on helping clinicians and patients improve outcomes through more effective self-management support for high-risk, complex patients, many with heart disease, hypertension, and/or other cardiovascular risk factors.

Dr. Feldman has served on a variety of advisory committees and technical expert panels sponsored by nonprofit and governmental organizations in both the U.S. and abroad.
