Hospitals appear to be treating Medicare patients in emergency departments and observation areas to avoid readmissions and the financial penalties associated with them, according to a new U.S. study.

“We have noticed that patients who come back to the hospital shortly after discharge are increasingly being treated in the [ED] or as observation stays—many of our colleagues across the country have also conveyed that they are being nudged to provide care in these settings, to make hospitals’ readmission rates look lower,” said Dr. Rishi K. Wadhera from Beth Israel Deaconess Medical Center and Harvard Medical School in Boston, who led the study.

Since 2012, an initiative by the Centers for Medicare and Medicaid Services (CMS) to improve the quality and value of patient care, known as the Hospital Readmissions Reduction Program (HRRP), has imposed financial penalties on hospitals with higher-than-expected rates of readmission within 30 days of discharge for patients initially admitted for heart failure, heart attack or pneumonia.

In fiscal year 2019, 82 percent of hospitals received such penalties.

Under the program, readmission rates have “declined modestly nationally,” Dr. Wadhera’s team writes in The BMJ. But HRRP does not count emergency department visits or so-called observation stays as readmissions, so the researchers wondered if total hospital revisits for these conditions had really changed or just shifted category.

They used Medicare files to examine not only readmissions, but also treat-and-discharge visits to an emergency department and observation stays that did not result in readmission for the three conditions covered under HRRP.

Between January 2012 and October 2015, the total number of hospital revisits within 30 days of discharge per 100,000 patient discharges increased overall by 23 visits per month, the study team found.

This increase was a result of a rise in treat-and-discharge visits to an emergency department (by 23 visits per month per 100,000 patient discharges) and an increase in observation stays (by 22 visits per month per 100,000 discharges). Actual readmissions, though, decreased by 23 visits per month per 100,000 patient discharges during this period.

Results were similar when only first hospital revisits were counted. These changes were also similar among patients younger and older than 80 years, among men and women, and among white and non-white patients, although increases in observation stays within 30 days of discharge were higher among non-white patients.

“While the spirit of the HRRP is to push hospitals to improve discharge planning and care transitions, to reduce the likelihood of returning to the hospital, mounting evidence suggests the program has had unintended effects,” Dr. Wadhera said.
