Factors predicting quality of life and societal participation after survival of a cardiac arrest

AIM: For those patients who suffer unfavourable outcome after survival of cardiac arrest, it is important to know whether this can be predicted at an early stage. Support can subsequently be provided. This study aimed to identify early prognostic factors of quality of life (QOL) and societal participation at one year post-cardiac arrest.METHODS: The design was a prospective longitudinal cohort study following cardiac arrest survivors up to one year. Prognostic personal, injury-related, function-related and subjective outcome factors were selected and entered into a hierarchical regression model to assess whether they were predictive of QOL and societal participation at one year post-cardiac arrest.RESULTS: Hundred and ten cardiac arrest survivors were included. Not having a partner, more functional limitations (at two weeks) and cognitive complaints were significantly predictive of lower physical QOL, while higher levels of anxiety and depression symptoms (at three months) were significant predictors of mental QOL. A neurological history and higher levels of anxiety and depression symptoms were significantly predictive of lower brain injury-specific QOL. Societal participation was only predicted by premorbid functioning.CONCLUSION: This study identified prognostic factors of QOL and societal participation one year after survival of cardiac arrest. Screening of these factors in early stages can identify those survivors with possibly unfavourable QOL at one year post cardiac arrest. For those survivors, preventive and targeted interventions may be offered.
