About the Investigator

Renee Pekmezaris received her PhD from Hofstra University in 1987 in Psychology, specializing in applied research and program evaluation. For the first ten years of her career, she served the Long Island, New York (NY) community as research and executive director of the Nassau-Suffolk Health Systems Agency, the NY State-designated health planning and regulatory agency for Long Island.

Dr. Pekmezaris joined Northwell Health as vice president for community health and health services research in 2005. As a multimethod researcher with expertise in quasi-experimental design and qualitative approaches, she leads a team of health services researchers responsible for conducting studies to improve quality of life for patients living with chronic disease, including community-based participatory research. She has authored over 80 peer review publications, has served as a panel reviewer for the National Science Foundation/NIH and journal reviewer for PharmoEconomics, Medical Education, Journal for Healthcare Quality, Palliative Medicine, Journal of Clinical Oncology, Journal of Comparative Effectiveness Research and Health Services Research.

Many of Dr. Pekmezaris’ studies are focused on improving chronic disease management by leveraging the use of technology, such as telehealth technology. Her studies often involve partnering with community members and community-based organizations to better understand how healthcare issues uniquely affect diverse communities. Community-based participatory research approaches are used to engage community members in all aspects of the research process and implement interventions with the greatest impact. Our researchers utilize mixed methods in order to provide a broader perspective and a deeper understanding of the diseases being studied.

As of October 2018, the Health Services Research Division published over 80 research articles in peer reviewed journals, and has acquired $23.2 million in grant funding to support their research, including three disparity research grants from the Patient-Centered Outcomes Research Institute (PCORI) to adapt (via qualitative approaches) and test (via randomized control trials) home telemonitoring approaches for disparity patients living with heart failure, COPD and diabetes, respectively. These randomized clinical trials determine whether the health of Hispanic patients who receive this adapted telemonitoring intervention experience better health outcomes compared to those who receive standard outpatient care.

Dr. Pekmezaris previously served as research fellow of the Institute for Medical Effectiveness Research at Albert Einstein College of Medicine (AECOM), and is professor in the Center for Health Innovations and Outcomes Research at the Feinstein Institute for Medical Research and at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell.

Research Focus

The Community Health & Health Services Research Division, led by Renee Pekmezaris, PhD, conducts multidisciplinary research to examine how individual, social, and organizational factors affect healthcare delivery and patient outcomes.  Our team is well-versed in multimethod and quasi-experimental research approaches. Collaborating with investigators throughout the health system, they provide scientific consultation across a range of healthcare and community-based settings, focusing on “rightsizing” health utilization, reducing health disparities, and improving quality of life.

With an emphasis on the growing population of seniors in the New York metropolitan area, our team looks for solutions to improve quality of life for patients living with chronic illness by leveraging the use of technology, such as telehealth technology. We are actively studying remote patient monitoring with patients with heart failure, COPD and diabetes.

Remote patient monitoring- in the home- is one form of interactive technology that has the potential to enhance patient quality of life (QoL), as patients are able to stay in their own homes and stay connected to their support systems. It may also offer significant cost savings in its ability to allow practitioners to monitor, evaluate and educate patients from remote locations.
