Editor’s Note: This piece is part of an ongoing series. In a previous article (Winning on Stars: It Starts and Ends with Providers), we discussed the importance of underlying provider network performance in driving a plan’s overall Stars score. 2016 Star year analysis showed overall score was highly correlated with performance of a plan’s contracted provider network, with an R2 of 0.95 – near perfect correlation. In a future post, we’ll consider the program changes required to raise a plan’s score from 3.5 Stars to 4.
Plans have continued to mature in their approach to Stars. Over the past two years, they have become more effective and more efficient at driving high quality scores overall, demonstrated by significant increases in the 4-Star thresholds of key measures. Despite this maturing of Stars programs, however, the dependency on underlying provider performance remains very strong.
Our analysis of annual Stars metrics demonstrates a continued high correlation between a plan’s overall Stars score and their performance on provider-driven measures.
