A new study published in Health Affairs sought to establish whether surgical penalties introduced under the Hospital Readmissions Reduction Program (HRRP) reduced procedure-specific readmissions. The HRRP announced in 2010 to penalize excess readmissions for patients with selected medical diagnoses, was expanded in 2013 to include targeted surgical diagnoses, beginning with hip and knee replacements. Using Medicare claims, researchers evaluated the penalty announcements’ effects on risk-adjusted readmission rates, episode payments, lengths-of-stay, and observation status use. Risk-adjusted readmission rates declined for both procedures from 7.6 percent in 2008 to 5.5 percent in 2016. These rates were decreasing before the program was announced, but the rate of reductions doubled after the announcement of medical penalties in March 2010 (from −0.05 percentage points to −0.10 percentage points per quarter). After targeted surgical penalties (hips and knee replacements) were announced in August 2013, readmission reductions returned to near the baseline trend. During the same time period, mean episode payments and lengths-of-stay decreased substantially, and trends in observation status were unchanged. This suggests that medical readmission penalties led to readmission reductions for surgical patients as well, that targeted surgical penalties did not have an additional effect, and that readmission reductions are approaching a “floor” below which further reductions may be unlikely.
