Seniors with more continuity of care use the ER less

"Higher continuity of care was associated with lower risk of having any emergency department visit," said lead study author David Nyweide, Ph.D, of the Centers for Medicare & Medicaid Services in Baltimore, Md. "However, when one occurred, the patient was more likely to be hospitalized. One possible explanation is that when a patient with a usual care physician comes to the ER, the physician may provide clearer guidance on which situations are serious enough to warrant a hospital admission."

Researchers studied the administrative data of more than 3 million Medicare beneficiaries between 2011 and 2013 and found that the relative risk of an emergency department visit, observation stay or admission through the emergency department decreased up to 20 percent for patients with the highest, compared with the lowest, continuity of care.

"Visits with the same physician or a small number of physicians fosters long-term relationships for Medicare patients, which is ultimately good for their health," said Mr. Nyweide. "The critical factor seems to be consistent visits with one physician or few physicians, not lots of them. Seniors would be well-advised to maintain an ongoing relationship with the same physician for many reasons, including avoiding emergency department visits."
