Aim: To assess the impact of physical, mental and cognitive impairments on health-related quality-of-life (QoL) of individuals who have survived sepsis after admission to an Intensive Care Unit (ICU) in New Zealand.
Methods: Survivors from a trial investigating vitamin C as an adjunctive therapy in patients with sepsis in Christchurch Hospital ICU were invited to enrol in a longitudinal QoL follow-up study. Patients were interviewed at hospital discharge, 30, 90 and 180 days, using validated physical and mental health assessment questionnaires (Short-Form-36, EuroQol-5-Dimension). Cognitive function was monitored and results compared with New Zealand population norms.
Results: Eighteen of the 26 survivors participated in the 6-month QoL follow-up. At hospital discharge, there were significant physical and mental health issues in the participants interviewed, and although a majority of the subscales improved over the 6-month follow-up, physical function, role-physical and general health were still below population norms. Following discharge, objective parameters (mobility, self-care, usual activities) normalised within 3-6 months, while subjective measures (pain/discomfort and anxiety/depression) improved earlier and were better than population norms at 3-6 months. Cognitive dysfunction persisted over the follow-up period. Short-term (4-day) vitamin C intervention in the ICU did not affect health parameters post hospital discharge.
Conclusions: Survivors of septic shock experience elevated physical, mental and cognitive issues at discharge. Most mental health issues had resolved by 6 months, but some physical and cognitive issues had not returned to population norms. Short-term vitamin C administration did not improve long-term health-related QoL; however, ongoing vitamin C supplementation may be required.
