The Effect of Age on Resilience of Health-Related Quality of Life among Polytrauma Patients: a Cross-Sectional Multicenter Study

The aim of this study was to determine the impact of age on patient-reported health-related quality of life (HRQoL) and the capacity to show resilience—i.e., the ability to adapt to stressful adverse events—after sustaining a polytrauma. A cross-sectional multicenter cohort was conducted between 2013 and 2016 that included surviving polytrauma patients (ISS ≥ 16). HRQoL was obtained by the Short Musculoskeletal Function assessment and EuroQol (SMFA and EQ-5D-5L). The effect of age on HRQoL was tested with linear regression analysis. Next, the individual scores were compared with age- and sex-matched normative data to determine whether they showed resilience. Multivariate binary logistic regression was used to assess the effect of age on reaching the normative threshold of the surveys, correcting for several confounders. A total of 363 patients responded (57
