Telephone-based evaluation of cognitive impairment and mood disorders among out-of- hospital cardiac arrest survivors with good neurologic outcome: a retrospective cohort study

Abstract This study determined the incidence of the cognitive impairments and mood disorders by telephone-based evaluation using previously mentioned scoring systems in out-of-hospital cardiac arrest (OHCA) survival with good neurologic outcome. Retrospective, cross-sectional, single-center study was performed, and a total of 97 patients were analyzed. Telephone version of Montreal Cognitive Assessment, Alzheimer’s disease-8 were used for evaluating cognitive dysfunctions, and the Patient Health Questionnaire-9 and the Hospital Anxiety and Depression Scale were used for assessing mood disorders. Quality of life was measured with the European Quality of Life 5-Dimension 5-Levels questionnaire. About one fourth patients experienced cognitive impairments (n = 23, 23.7%) or mood disorders (n = 28, 28.9%). Combined mood disorders (adjusted OR 21.36, 95% CI 5.14–88.84) and hospital length of stay (adjusted OR 1.04, 95% CI 1.01–1.08) were independent risk factors. In case of mood disorders, combined cognitive impairments (adjusted OR 9.94, 95% CI 2.83–35.97) and non-cardiac cause of cardiac arrest (adjusted OR 11.51, 95% CI 3.15–42.15) were risk factors. Furthermore, the quality of life was significantly low in the group with both cognitive impairments and mood disorders. Cognitive impairments and mood disorders were common among patients with good neurologic recovery.
