Abstract 2676: Caregiving Demands After Sudden Cardiac Arrest Predict Poor Psychological Outcomes in Partners
The physical health and psychological well being of the partner is important in the recovery of the patient after cardiac illness.
Purpose: The purpose of this study was to determine the factors that predict poor psychological outcomes (STAI anxiety and CES-D depression) at 3 and 12 months after hospital discharge in partners of patients who were resuscitated from sudden cardiac arrest (SCA) and received an implantable cardioverter defibrillator (ICD).
Methods: A longitudinal prospective design was used to follow 102 patient-partner pairs from baseline ICD implantation through 1 year. Outcomes were measured at 3 times: hospital discharge, 3, and 12 months. Hierarchical linear regression was used to predict psychological outcomes of partners at each follow-up time. Caregiving demands was measured using the Experiences of Caregiving Inventory.
Results: ICD patients were 64.1±12 years old, 77% male, 89% Caucasian, 13% college graduates, and 34% employed. Partners were 62.4±11 years old, 80% female, 94% Caucasian, 17% college graduates, and 36% employed. Partner anxiety: At 3 months after the patient received an ICD, caregiving demands on the partner independently predicted an additional 7% of the variance in anxiety R2= 0.36, F=6.20 (8,75), p =0.001, when controlling for partner demographics, baseline partner anxiety, patient ICD shocks, patient physical and mental health, and patient hospitalizations. This model was also predictive of partner anxiety at 12 months, R2= 0.35, F=5.77 (7,76), p = 0.001. Partner depression: At 3 months caregiving demands on the partner also independently predicted an additional 3% of the variance in depression, after controlling for partner demographics, baseline partner anxiety, patient ICD shocks, patient physical and mental health, and patient hospitalizations, R2= 0.37, F=6.33 (7,76), p= 0.001. This model was also predictive of partner depression at 12 months, R2= 0.34, F=5.47 (8,75), p= 0.001.
Conclusion: Higher caregiving demands on the partner after the patient survives SCA predicts higher anxiety and depression of the partner at 3 and 12 months post-ICD. Interventions to reduce the burden of caregiving for partners after the patient has an ICD will improve the partner’s psychological adjustment in the first year.
