Implementation of the Hospital Readmissions Reduction Program (HRRP) following discharge of patients with Chronic Obstructive Pulmonary Disease (COPD) has led to a reduction in 30-day readmissions with unknown effects on post-discharge mortality.
To examine the association of HRRP with 30-day hospital readmission and 30-day post-discharge mortality rate in patients after discharge from COPD hospitalization.
Retrospective cohort study of readmission and mortality rates in a national cohort (N=4,587,542) of admissions of Medicare fee-for-service beneficiaries 65 years or older with COPD from 2006 to 2017.
Data were analyzed for three non-overlapping periods based on implementation of the HRRP specific to COPD: 1) pre-announcement (December 2006- March 2010), 2) announcement (April 2010-August 2014) and 3) Implementation (October 2014-November 2017).
The 30-day readmission rate decreased from 20.54% in the pre-announcement period (December 2006-July 2008) to 18.74% in the implementation period (May 2016-November 2017). The 30-day risk-standardized post-discharge mortality rates were 6.91%, 6.59% and 7.30% for the pre-announcement, announcement and implementation periods, respectively. Generalized Estimating Equations analyses estimated an additional 1,196 deaths (October 2014-April 2016) and 3,858 deaths (May 2016-November 2017) during the HRRP implementation period.
We found a reduction in 30-day all-cause readmission rate during the implementation period compared to the pre-announcement phase. HRRP implementation was also associated with a significant increase in 30-day mortality after discharge from COPD hospitalization. Additional research is necessary to confirm our findings and understand the factors contributing to increased mortality in patients with COPD in the HRRP implementation period.
