PHILADELPHIA — Patients with low socioeconomic status use emergency and hospital care more often than primary care because they believe hospital care is more affordable and convenient, and of better quality than care provided by primary care physicians, according to the results of a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania. The results of the study, appearing in the July issue of Health Affairs (and featured on its cover), have significant implications for policy initiatives such as the Affordable Care Act that seek to lower health care costs by reducing avoidable hospitalizations, readmissions, and emergency department visits.
“Our findings suggest that efforts to reduce hospital readmissions solely by improving the quality of hospital care could backfire by making hospitals even more attractive for low-SES patients,” said lead author Shreya Kangovi, MD, director of the Penn Center for Community Health Workers and a Robert Wood Johnson Foundation Clinical Scholar in the Department of Medicine at the Philadelphia Veterans Affairs Medical Center. “To generate system-wide savings, it’s important to make outpatient services more appealing to low-SES patients by addressing their concerns around cost, quality and accessibility. For instance, health systems might reduce barriers such as complicated referral systems that are often required for seeing specialists. These barriers may actually drive patients to the higher-cost, one-stop-shop hospital setting.”
Data consistently show that low-SES patients receive health care differently than high-SES patients; low-SES patients use less preventive care and are more likely to become acutely ill and require urgent hospital care. This is not just explained by lack of insurance. This pattern of health care use, which costs $30.8 billion annually and leads to poor health outcomes, is a lose-lose for patients and payers.
To better understand the reasons for this persistent discrepancy, Penn researchers worked with trained community health workers to conduct detailed interviews with 40 low-SES Philadelphia patients (low-income, and uninsured or on Medicaid) on why they choose to visit the hospital/emergency department over a primary care physician. Community health workers have been shown to engender trust and form close relationships with low-income patients.
The study also uncovered what appeared to be two very different groups of low-SES patients: super-utilizers whose hospital use was driven by trauma and social dysfunction, and lower-utilizers who reported postponing ambulatory care because of caregiver burden and job pressures.
“This study debunks the perception that low-SES individuals abuse the emergency room and need to be educated on its proper use,” said David Grande, MD, MPA, assistant professor of Medicine at Penn Medicine and senior author on the study. “To the contrary, these patients eloquently explained to us how we have built a health care system that incentivizes them to wait and get sick in order to get care that is more costly to society.”
Additional Penn authors on the study are Frances K. Barg, Tamala Carter, Judith A. Long, and Richard Shannon.
This study was supported by the Leonard Davis Institute of Health Economics at the University of Pennsylvania.
Penn Medicine is one of the world's leading academic medical centers, dedicated to the related missions of medical education, biomedical research, and excellence in patient care. Penn Medicine consists of the Raymond and Ruth Perelman School of Medicine at the University of Pennsylvania (founded in 1765 as the nation's first medical school) and the University of Pennsylvania Health System, which together form a $4.3 billion enterprise.
The Perelman School of Medicine has been ranked among the top five medical schools in the United States for the past 16 years, according to U.S. News & World Report's survey of research-oriented medical schools. The School is consistently among the nation's top recipients of funding from the National Institutes of Health, with $398 million awarded in the 2012 fiscal year.
The University of Pennsylvania Health System's patient care facilities include: The Hospital of the University of Pennsylvania -- recognized as one of the nation's top "Honor Roll" hospitals by U.S. News & World Report; Penn Presbyterian Medical Center; Chester County Hospital; Penn Wissahickon Hospice; and Pennsylvania Hospital -- the nation's first hospital, founded in 1751. Additional affiliated inpatient care facilities and services throughout the Philadelphia region include Chestnut Hill Hospital and Good Shepherd Penn Partners, a partnership between Good Shepherd Rehabilitation Network and Penn Medicine.
Penn Medicine is committed to improving lives and health through a variety of community-based programs and activities. In fiscal year 2012, Penn Medicine provided $827 million to benefit our community.
