The answer is ‘perhaps’ according to a new paper by Wadhera et al. (2018). They use data from 2005 to 2015, and apply an inverse probability–weighted 30-day and 45-day post-discharge mortality measure stratified by whether there was an associated readmission. They examine admissions for acute myocardial infarction, heart failure, and pneumonia.
Among Medicare beneficiaries, the HRRP was significantly associated with an increase in 30-day postdischarge mortality after hospitalization for HF and pneumonia, but not for AMI…The overall increase in mortality among patients with HF and pneumonia was mainly related to outcomes among patients who were not readmitted but died within 30 days of discharge.
