The reduction in the nationwide Medicare 30-day readmission rate observed in 2012 was not primarily driven by compensatory increases in post-discharge emergency department visits or observation stays.
Gerhardt et al. (2014) conducted an observational in Acute hospital inpatient stay. Calendar year 2012 vs. Calendar year 2011 was evaluated on National, all-cause, 30-day hospital readmission rate (p=<0.0001). The national 30-day hospital readmission rate among Medicare beneficiaries significantly declined from 19.0% in 2011 to 18.5% in 2012, a reduction that was not primarily driven by increases in post-discharge ED visits or observation stays.
