Nearly one of every four people (24.7%) hospitalized in the U.S. with congestive heart failure is readmitted within 30 days.<ref>Elixhauser A, Steiner C.

Heart failure is a leading cause of hospital readmissions in the U.S. People aged 65 and older were readmitted at a rate of 24.5 per 100 admissions in 2011. In the same year, heart failure patients under Medicaid were readmitted at a rate of 30.4 per 100 admissions, and uninsured people were readmitted at a rate of 16.8 per 100 admissions. These are the highest readmission rates for both categories. Notably, heart failure was not among the top-10 conditions with the most 30-day readmissions among the privately insured.<ref>{{cite journal | vauthors = Hines AL, Barrett ML, Jiang HJ, Steiner CA | title = Conditions With the Largest Number of Adult Hospital Readmissions by Payer, 2011. | journal =HCUP Statistical Brief |issue=172 | publisher = Agency for Healthcare Research and Quality | location = Rockville, MD | date = April 2014 | pmid = 24901179 | url = http://hcup-us.ahrq.gov/reports/statbriefs/sb172-Conditions-Readmissions-Payer.jsp | url-status = live | archive-url = https://web.archive.org/web/20160304052719/http://hcup-us.ahrq.gov/reports/statbriefs/sb172-Conditions-Readmissions-Payer.jsp | archive-date = 4 March 2016 | df = dmy-all }}</ref>
