MercyOne Des Moines named one of the nation's 50 Top Cardiovascular Hospitals 2020

November 25, 2019

MercyOne Des Moines Medical Center has been named one of the nation’s 50 Top Cardiovascular Hospitals by IBM Watson HealthTM. The study spotlights the top-performing cardiovascular hospitals in the U.S. based on a balanced scorecard of publicly available clinical, operational and patient satisfaction metrics and data.

“Excellence in cardiac and vascular care is a legacy of MercyOne Des Moines Medical Center,“ said president Karl Keeler. “The integrated care provided by our physicians, surgeons and colleagues at MercyOne Iowa Heart Center is second to none. Their ongoing commitment to research and our patients sets them apart, in providing access to the latest treatments and care available.”

“To be recognized as one of the top 50 cardiovascular hospitals in the country is quite an honor and something to be very proud of,” said Dr. Mark Tannenbaum, interventional cardiologist and Chief Physician Officer of MercyOne Iowa Heart Center. “This is a testament which reinforces to our patients and their families that when they choose MercyOne Iowa Heart Center for their heart-health needs, they’re getting the best possible care.”

The study is part of the IBM Watson Health 100 Top Hospitals® program, using independent and objective research to analyze hospital and health system performance in key clinical and operational areas for selected cardiovascular procedures and medical care. Indicators include: risk-adjusted inpatient mortality index, risk-adjusted complications index, mean 30-day risk-adjusted mortality rate, mean 30-day risk-adjusted readmission rate, severity-adjusted length of stay, case mix- and wage-adjusted inpatient cost per case, 30-day episode payment, and adjusted operating profit margin. The study has been conducted annually since 1998. 

Based on the results of this year’s study, the study extrapolates if all Medicare inpatients received the same level of care as those treated in the award-winning facilities:

  • More than 11,000 additional lives could be saved;
  • More than 2,800 additional heart patients could be complication-free; and
  • More than $1.5 billion could be saved.

“By finding ways to continuously improve and innovate, the winners of our 50 Top Cardiovascular Hospitals study are identifying opportunities to deliver healthcare value to patients, communities, and payers,” said Ekta Punwani, MHA, 100 Top Hospitals® program leader at IBM Watson Health. “The top performing hospitals demonstrated better clinical care and were more efficient than their peers at delivering this care.”
