Comparison of pre-injury recalled Health Status (HS) data of trauma patients and HS of the general population

•Injured patients report better recalled pre-injury health status (HS) compared to the HS of the reference cohort.•Compared to the reference cohort, the injury cohort reported prior to the injury significantly less problems on the 'pain/discomfort' and 'anxiety/depression' dimensions of the EuroQol-five-dimension-3-level (EQ-5D-3L) questionnaire.•After adjustment for age, gender and educational level, there is still a bias in retrospectively collected pre-injury HS.•Compared to the reference cohort, the injury cohort reported prior to the injury significantly more problems on the 'self-care' dimension of the EQ-5D-3L. Significant differences exist between retrospectively collected pre-injury Health Status (HS) of trauma patients and the HS of the general population. Compared to the general population, the trauma population includes a larger proportion of individuals with a low level of socio-economic status. The aim was to compare retrospectively collected pre-injury HS with HS of a sample of Dutch individuals not only adjusted for age and gender, but also for educational level. Within three months post-trauma, pre-injury HS (n = 2987) was collected by using the EuroQol-five-dimension-3-level (EQ-5D-3L) questionnaire. Data were abstracted from the Brabant Injury Outcome Surveillance. The reference cohort (n = 1839) included a sample of the Dutch general population. Multiple regression was used to compare HS of both cohorts. A higher recalled pre-injury EQ-5D-3L score of the injury cohort was reported compared to the HS of the reference cohort after adjustment for age (β = 0.014 [95% CI: 0.001,0.027] for males and β = 0.018 [95% CI: −0.001, 0.036] for females). After adjustment for age and educational level, the Beta showed a ≥10% increasement: males; unadjusted β = 0.006 [95% CI: −0.007, 0.019] to β = 0.014 [95% CI: 0.001, 0.027] after age adjustment to β = 0.020 [95% CI: 0.007, 0.033] after adjustment for age and educational level, females; unadjusted β = −0.018 [95% CI: −0.035, −0.001] to β = 0.018 [95% CI: −0.001, 0.036] after age adjustments to β = 0.025 [95% CI: 0.007, 0.043] after adjustments for age and educational level. After adjustment for age, gender and educational level, the injury cohort reported prior to the trauma less problems on the ‘pain/discomfort’ (OR = 0.522 [95% CI: 0.454, 0.602]) and the ‘anxiety/depression’ (OR = 0.745 [95% CI: 0.619, 0.897]) dimensions, as compared to the reference cohort. In contrast, the injury cohort reported s
