About 20 percent of patients who were hospitalized for cardiac arrest were readmitted to the hospital within 30 days of discharge, according to a study published in JAMA Network Open.
U.S. researchers examined data from the Nationwide Readmissions Database from 2010 to 2014.
There were 251,346 patients who survived the initial hospitalization for cardiac arrest. Of the survivors, 19.6 percent were readmitted within 30 days of discharge. About 72 percent of the 30-day readmissions were due to noncardiac causes.
Infections, such as pneumonia or sepsis, were the most prevalent noncardiac cause of readmission, followed by chronic obstructive pulmonary disease or respiratory failure.
Of cardiac-related readmissions, heart failure and arrhythmia were the most common causes.
