The renamed Truven Health Analytics research initiative found that the highest performers achieved better care consistency and alignment across facilities.IBM Watson Health has revealed its 15 Top Health Systems based on overall organizational performance. Formerly known as the Truven Health Analytics 15 Top Health Systems, the rankings have been conducted annually since 2008 and reflect operational and clinical excellence, IBM Watson Health said. Top systems earned the ranking at least in part through more consistent care across member hospitals, finding a small but discernable difference in the level of individual hospital alignment within the top-performing health systems as well as 1.9 percent lower volatility, the group said.Demonstrating what separates the best from the rest, top hospitals achieved several benchmarks over their peers including: 14.6 percent fewer in-hospital deaths, 17.3 percent fewer complications and 16.2 percent fewer healthcare-associated infections. They also had a median severity-adjusted length of stay roughly one half-day shorter than peers and median ED wait times 40 minutes shorter per patient as well as 5.6 percent lower per episode combined in-hospital and post-discharge costs. HCAHPS scores for overall hospital experience were also 2.3 percent higher.
