Morita Y, et al. - Researchers estimated the burden and patterns of 30-day readmission following in-hospital cardiopulmonary resuscitation (ICPR) using data from the 2014 US Nationwide Readmission Database. They identified 27,278 index admissions who underwent ICPR using International Classification of Diseases-Ninth Revision-Clinical Modification codes, of which readmission within 30 days was observed for 5,439 (20.0%). 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. Significant cost burden and patient comorbidities were linked to 30-day readmissions after ICPR. Suitable interventions and reduced readmissions and healthcare costs may result from better recognition of predictors and individualization of care.
