The benefits of health system member membership have been hard to prove statistically, but a new study from the 100 Top Hospitals® program does just that. By comparing the performance and performance improvement of hospitals that are members of health systems and those that are not, we found that health system members significantly outperform -- and improve significantly faster than -- independent hospitals.
Hospitals that are system members have better balanced scorecard performance and rates of improvement. In both one-year performance and five-year improvement on the 100 Top Hospitals metric, hospital system members ranked in a higher percentile of performance than independent hospitals.
The study also found that hospitals that are system members have a higher probability of being a 100 Top Hospitals award winner. For this analysis, we simply calculated the percentage of 100 Top Hospitals 2012 award winners for both the independent hospital and hospital system member groups. We found that the hospital system members had a substantially higher probability of winning the award.
