Nursing Home Admission and Home Care Initiation After Acute Aortic Dissection: A Nationwide Registry-Based Cohort Study.

Background: Little is known about long-term outcomes beyond survival following acute aortic dissection. The aim of this research was to evaluate rates of home care initiation and nursing home admission during the first year after discharge and to assess factors associated with these needs.

Methods: All patients in Denmark with a first-time diagnosis of acute aortic dissection type A or B between 2006 and 2015 were identified using national registries. Patients discharged alive without nursing home or home care use before aortic dissection were included, along with age-matched and sex-matched population controls without aortic dissection (at a ratio of 1:5). Cause-specific multivariable Cox regression was used to derive adjusted hazard ratios.

Results: The study population comprised 1093 patients and 5465 control individuals with a median (IQR) age of 64 (55-71) years; 70.6% were men. During their hospital stay, 2.7% of patients were registered with a first-time diagnosis of stroke, 7.1% with heart failure, and 2.2% with acute kidney failure; 5.9% of patients needed first-time dialysis. During the first year after discharge, 0.8% of patients who had had aortic dissection were admitted to a nursing home, 7.8% started home care, and 5.9% died. Among controls, these rates were 0.2%, 1.2%, and 1.2%, respectively. Patients who had had aortic dissection had significantly increased risk of initiating home care (hazard ratio, 7.47 [95% CI, 5.38-18.37]; P < .001) and of being admitted to a nursing home (hazard ratio, 4.28 [95% CI, 1.73-10.59]; P = .001). Initiation of home care and nursing home admission were related to advanced age, female sex, preexisting comorbidities, in-hospital complications, and conservative management of type A aortic dissection.

Conclusion: Only a small proportion of patients who survived an aortic dissection needed home care or nursing home admission after hospital discharge.
