Abstract and Introduction
Population health focuses on the specific health needs of an individual within a defined population.
"In order to truly measure a patient's health outcomes and identify best practices, providers must evaluate a group of people with similar health needs," explains Joseph Damore, vice president of population health management for Charlotte-N.C.-based Premier, Inc. "Once we understand a population's outcomes, we can then target the individual."
Fundamentally, population health is about individualized care and intervening earlier in order to get a better outcome based on what generally works for the population. It's also about identifying populations that need specific, targeted care, such as diabetic and oncology patients.
Back in 2003, David A. Kindig MD, PhD, and Greg Stoddart, PhD, defined population health as "the health outcomes of a group of individuals, including the distribution of such outcomes within the group."
In order to achieve population health, according to Nick Fitterman, MD, SFHM, vice chair of hospital medicine for the Hofstra North Shore-LIJ School of Medicine in Hempstead, N.Y., "it is necessary to reduce health inequities or disparities among different populations due to, among other factors, the social determinants of health, which include social, environmental, cultural, and physical factors."
Even though the concept of population health emerged more than 25 years ago, Dr. Fitterman points out that, until recently, the U.S. healthcare system has looked at an individual's episodic illness rather than at population health, which focuses on wellness, prevention, and coordinated care across the continuum.
Marianne McPherson, PhD, MS, senior director of programs, research, and evaluation for the National Institute for Children's Health Quality in Boston, says it is important for hospitalists to focus on both the patient and the population.
"You need to understand the particular factors facing the patient in front of you and understand that that individual is a product of a variety of different circumstances," she says. "If you only look at an individual's health, you can miss important trends across a group of patients within a population or community.
"By looking at both the individual and entire population, you can provide the most effective healthcare and health promotion."
