No one wants to be readmitted to a hospital, but it does beat one alternative: death.
As Medicare prepares to start punishing hospitals with higher than expected readmission rates, new government data show that some hospitals with high readmissions are actually doing a better job than most in keeping Medicare patients alive.
Beth Israel Deaconess Medical Center in Boston and Olympia Medical Center in Los Angeles both had higher than average readmission rates for all three conditions that Medicare tracks publicly: heart attack, heart failure and pneumonia.
But Beth Israel and Olympia also had lower rates of mortality within 30 days of discharge for patients with all three of these conditions, according to the latest data published last week on Medicare's Hospital Compare website.
In addition to Beth Israel and Olympia, three other hospitals had unusually high readmission rates for heart attack but lower than average mortality rates:
Maimonides Medical Center in Brooklyn, N.Y. Henry Ford Hospital in Detroit; and North Shore University Hospital in Manhasset, N.Y.
Thirty-one hospitals besides Beth Israel and Olympia had low mortality for heart failure patients even as they had high readmission rates. And 14 hospitals besides Beth Israel and Olympia had low mortality for pneumonia patients even as they had high pneumonia readmission rates.
To be sure, these hospitals represent a small fraction of the nation's 4,000 acute care hospitals. But some researchers say this is another reason to be wary of the upcoming financial penalties Medicare plans to levy against hospitals with higher than expected readmissions rates.
Researchers at the Cleveland Clinic studied heart failure readmissions and found high rates were associated with lower mortality. In a 2010 letter to the New England Journal of Medicine, the authors wrote:
"Our findings suggest that readmissions could be "adversely" affected by a competing risk of death — a patient who dies during the index episode of care can never be readmitted. Hence, if a hospital has a lower mortality rate, then a greater proportion of its discharged patients are eligible for readmission. As such, to some extent, a higher readmission rate may be a consequence of successful care. Furthermore, planned readmissions for procedures or surgery may represent appropriate care that decreases the risk of death, but this is not accounted for in Hospital Compare."
Starting in October 2013, Medicare plans to take mortality rates into account when reimbursing hospitals under its so-called value-based purchasing formula. Mortality rates will initially count for 25 percent of the bonuses or penalties hospitals will receive, with the rest determined by patient ratings and measures showing how often hospitals followed basic clinical care guidelines.
Separately, Medicare recently awarded Beth Israel a $4.9 million grant to work on improvements to care in the month after hospital discharge. The goal: cut hospital readmissions within 30 days by 30 percent.
