Quality of Life and Functional Outcomes 12 Months After Out-of-Hospital Cardiac Arrest
Background—Out-of-hospital cardiac arrest (OHCA) is a significant global health problem. There has been considerable investment in improving the emergency medical response to OHCA, with associated improvements in survival. However, concern remains that survivors have a poor quality of life. This study describes the quality of life of OHCA survivors at one year post arrest in Victoria, Australia.
Methods and Results—Adult OHCA patients who arrested between 2010 and 2012 were identified from the Victorian Ambulance Cardiac Arrest Registry. Paramedics attended 15,113 OHCA patients of which 46.3% received an attempted resuscitation. 927 (13.2%) survived to hospital discharge of which 76 (8.2%) died within 12-months. Interviews were conducted with 697 (80.7%) patients or proxies, who were followed-up via telephone interview, including the Glasgow Outcome Scale - Extended (GOS-E), the twelve-item short form (SF-12) health survey and the EuroQol (EQ-5D). The majority (55.6%) of respondents had a good recovery via the GOS-E≥7 (41.1% if patients who died post discharge were included and non-respondents were assumed to have poor recovery). The mean EQ-5D index score for respondents was 0.82 (SD 0.19), which compared favourably with an adjusted population norm of 0.81 (SD 0.34). The mean SF-12 Mental Component Summary score for patients was 53.0 (SD 10.2), while the mean Physical Component Summary score was 46.1 (SD 11.2).
Conclusions—This is the largest published study assessing the quality of life of OHCA survivors. It provides good evidence that many survivors have an acceptable quality of life twelve months post arrest, particularly when compared to population norms.
