Health-related quality of life in critically ill survivors: specific impact of cardiac arrest in non-shockable rhythm

Background

Intensive care has a strong impact on health-related quality of life (HRQOL). The specific impact of cardiac arrest in non-shockable rhythm is poorly known. Patients and methods We gathered patients included in two randomized controlled trials (AWARE and HYPERION). The HYPERION trial included ICU-treated non-shockable cardiac arrest patients. The AWARE study included ICU patients requiring mechanical ventilation. We compared the 3-months HRQOL of these patients to those of a large sample of the French general population. Physical and mental dimension were compared. Multivariable linear regression was used to pick up factors associated with HRQOL

Results

72 and 307 patients of the HYPERION and the AWARE studies were compared to 20,574 French controls. ICU patients evidenced lower scores in all the SF-36 dimensions compared to the controls. Similar scores were observed in both HYPERION and AWARe trials. The physical component score was lower in patients from the HYPERION trial compared to those from the AWARE trials and to controls (38.6 [29.6-47.8], 35.4 [27.5-46.4] vs. 53.0 [46.0-56.7], $$\hbox {p}<0.001$$ p < 0.001 ). After adjustment for age and gender, HYPERION and AWARE trial status were associated wit lower physical component score. Conclusion Health-related quality of life of unshockable cardiac arrest survivors evaluated at 3 months was similar to ICU survivors and significantly lower than in individuals from general population, especially in the physical dimensions.
