ObjectivesTo determine whether 30-day readmissions were associated with presence of cognitive impairment more in elderly adults with heart failure (HF) than in those with other diagnoses and whether medical teams recognized cognitive impairment.DesignOne-year prospective cohort quality improvement program of cognitive screening and retrospective chart review of documentation and outcomes.SettingAcademic tertiary care hospital medical unit with a cardiovascular focus and an enhanced discharge program of individualized patient education.ParticipantsIndividuals aged 70 and older screened before home discharge (241 admission encounters; 121 with HF as a primary diagnosis, 120 without). The HF cohort included individuals with preserved and reduced ejection fraction. Individuals who had undergone transplantation, ventricular assist device implantation, or hemodialysis or who had a primary oncology diagnosis or hospice referral were excluded.MeasurementsMini-Cog administered 48 hours or less before discharge, 30-day all-cause readmission rates, documentation of dementia or cognitive impairment, and caregiver education.ResultsMini-Cog scores were less than 4 (indicating cognitive impairment) in 157 encounters (82 (67.7%) with HF, 75 (62.5%) without). Mini-Cog scores were similar in rate and distribution between groups. Individuals with HF and cognitive impairment had a significantly higher 30-day readmission rate than did the other groups (26.8% vs 13.2%; P = .01; HF, no cognitive impairment, 12.8%; no HF, no cognitive impairment, 13.3%; cognitive impairment, no HF, 13.3%). In individuals with HF and cognitive impairment, those with documented caregiver education had lower readmission rates than those without (14.3% vs 36.2%; P = .03). Fewer than 9% had documentation of cognitive impairment in the medical record.ConclusionCognitive impairment, which is frequently undocumented, may indicate greater risk of readmission for individuals with HF than those without. Screening for cognitive impairment, adapting discharge for it, and involving family and caregivers in discharge education may help reduce readmissions.© 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.
