Abstract

Aim: To estimate the proportion of significant posttraumatic stress (PTS) in both cardiac survivors with good neurologic recovery and informal caregivers, and to pilot test the hypothesis that greater PTS are associated with worse quality of life (QoL) in both cardiac arrest survivors and informal caregivers of cardiac arrest survivors.

Methods: We distributed an online survey to survivor and caregiver members of the Sudden Cardiac Arrest Foundation. Participants provided demographic and cardiac arrest characteristics and completed the PTSD Checklist-5 (PCL-5), the Lawton Instrumental Activities of Daily Living scale, and the WHOQOL-BREF. We identified covariates through bivariate correlations or linear regressions as appropriate. Six multiple regression models (three each for survivors and caregivers) examined associations between PCL-5 scores with each QoL subscale, adjusted for covariates identified from the bivariate models.

Results: We included 169 survivors (mean months since arrest: 62.8, positive PTS screen: 24.9%) and 52 caregivers (mean months since arrest: 43.2, positive PTS screen: 34.6%). For survivors, the following showed significant bivariate associations with QoL: Lawton scores, daily memory problems, sex, months since arrest, age, and income; for caregivers, months since arrest, age, and income. In adjusted models, greater PCL-5 scores were associated with worse QoL (β: -0.35 to -0.53, p < .05).

Conclusions: Our pilot results suggest that PTS are prevalent years after the initial cardiac arrest and are associated with worse QoL in survivors and informal caregivers. Further study is needed to validate these findings in a larger, representative sample.
