Improvement requires evaluation of programs & initiatives. We utilize rigorous methods to evaluate programs and their impact on clinical, quality, and cost outcomes.
VSSL members have led large-scale evaluations of quality- and value-based payment and delivery programs, and their impact on patients. Examples of this work:
Program: Bundled payments (prominent payment model for improving the value of care)
Examples: Over the last 5 years, VSSL Director Dr. Joshua Liao and colleagues have been at the forefront of using advanced statistical methods to evaluate the impact of nationwide bundled payment programs.
As a part of this portfolio of work, Dr. Liao and colleagues recently used advanced econometric methods to evaluate the long-term association between hospital participation in joint replacement bundles and quality, and cost outcomes. Main findings included:
* 1.6% differential decrease in average episode spending
* These savings were driven by early, not late, participants
* No differential changes in quality outcomes
In a separate study, Dr. Liao and colleagues evaluated how hospital co-participation in (i.e., simultaneous participation in both) joint replacement bundles and accountable care organizations impacted outcomes. They found that compared to hospitals bundling joint replacement only, those co-participating in joint bundles and accountable care organizations had differential changes in 90-day unplanned readmissions and post-discharge care utilization patterns.
