The finding may provide some reassurance for those who have worried about a shortage of health care workers and whether they will be able to meet the nation’s growing burden of chronic diseases.
“Access to primary care doctors is critical to population health and to reduce health care disparities in this country,” said Donglan Zhang, PhD, an assistant professor of public health at the University of Georgia, Athens.
However, many counties remain underserved, Dr. Zhang said in an interview. The need for primary care in the United States is increasing not only with population growth but because the population is aging.
Dr. Zhang and colleagues published the finding in JAMA Network Open.
Many previous reports have warned of a shortage in primary care providers. To examine recent trends in the primary care workforce, Dr. Zhang and colleagues obtained data on all the primary care clinicians registered with the Centers for Medicare & Medicaid Services from 2009 to 2017.
For the study, the researchers included general practitioners, family physicians and internists without subspecialties, nurse practitioners, and physician assistants. They then compared the number of providers with the number of residents in each county as recorded by the US Census, using urban or rural classifications for each county from the Centers for Disease Control and Prevention.
Because the U.S. Health Resources and Services Administration defines a primary care “shortage” as fewer than 1 primary care practitioner per 3,500 people, the researchers focused on this ratio. They found that the number of nurse practitioners and physician assistants was increasing much faster than the number of primary care physicians. This was true especially in rural areas, but the percentage increase for both nurse practitioners and physician assistants was lower in rural areas versus urban.
The researchers also found that there were more primary care physicians per capita in counties with higher household incomes, a higher proportion of Asian residents, and a higher proportion of college graduates.
They didn’t find a significant association between the median household income and per capita number of nurse practitioners.
They found that counties with a higher proportion of Black and Asian residents had a higher number of nurse practitioners per capita. But they found an opposite association between the proportion of Black residents and the number of physician assistants per capita.
The authors hypothesized that health care reform, particularly the passage of the Affordable Care Act in 2010, may explain the recent increase in the primary care workforce. The legislation expanded the number of people with health insurance and provided incentives for primary and preventive care.
Another factor behind the increase in the primary care workforce could be state laws that have expanded the scope of practice for nurse practitioners and primary care providers, she said.
Numbers may overestimate available care
The gap between rural and urban areas could be even wider than this study suggests, Ada D. Stewart, MD, president of the American Academy of Family Physicians, said in an interview. Many nurse practitioners and physician assistants don’t actually practice primary care, but instead assist physicians in other specialties such as orthopedics or general surgery.
“They are part of a team and I don’t want to diminish that at all, but especially when we talk about infant and maternal mortality, family physicians need to be there themselves providing primary care,” she said. “We’re there in hospitals and emergency rooms, and not just taking care of diabetes and hypertension.”
In addition, the primary care workforce may have been reduced since the conclusion of the study period (Dec. 31, 2017) as a result of the COVID-19 pandemic forcing some primary care physicians into retirement, Dr. Stewart said.
Measures that could help reduce the disparity include a more robust system of teaching health centers in rural counties, higher reimbursement for primary care, a lower cost of medical education, and recruiting more people from rural areas to become physicians, Dr. Stewart said.
Telehealth can enhance health care in rural areas, but many people in rural areas lack internet or cellular service, or don’t have access to computers. “We don’t want to create another healthcare disparity,” she said.
And physicians can get to know their patients’ needs better in a face-to-face visit, she said. “Telehealth does have a place, but it does not replace that person-to-person visit.”
This study was funded by National Institute on Minority Health and Health Disparities. Dr. Zhang and Dr. Stewart disclosed no relevant financial relationships.
