Morita Y, et al. - Researchers used the US 2014 Nationwide Readmission Database (NRD) to determine the burden and trends of 30-day readmission following in-hospital cardiopulmonary resuscitation (ICPR). They analyzed incidence, predictors, causes, and costs of 30-day readmission with discharge weights to obtain national estimates. A total of 5,439 (20.0%) among the 27,278 index admissions that survived to hospital discharge after ICPR sought readmission within 30 days. Independent predictors of 30-day readmission were length of stay (LOS) ≥ 11 days during index hospitalization, chronic pulmonary disease, congestive heart failure, renal failure, discharge from the teaching metropolitan hospital, Medicare insurance, depression, and diabetes. Most of the readmissions were due to sepsis, heart failure, and respiratory failure. Findings revealed patient comorbidities and significant cost burden related to 30-day readmissions after ICPR.
