BackgroundWhiplash injuries show a variable prognosis which is difficult to predict. Most individuals experiencing whiplash injuries rapidly recover but a significant proportion develop chronic symptoms and ongoing disability.PurposeBy employing longitudinal data, we investigated how psychological and physical symptoms, self-rated health, use of health services and medications, health behavior and demographic factors predict recovery from whiplash.MethodData from two waves of a large, Norwegian, population-based study (The Nord-Trøndelag Health Study: HUNT2 and HUNT3) were used. Individuals reporting whiplash in HUNT2 (baseline) were identified in HUNT3 11 years later. The characteristics of individuals still suffering from whiplash in HUNT3 were compared with the characteristics of individuals who had recovered using Pearson's chi-squared test, independent sample t-tests and logistic regression.ResultsAt follow-up, 31.6 % of those reporting whiplash at baseline had not recovered. These individuals (n = 199) reported worse health at baseline than recovered individuals (n = 431); they reported poorer self-rated health (odds ratio [OR] = 3.12; 95 % confidence interval [CI], 2.20-4.43), more symptoms of anxiety (OR = 1.70; 95 % CI, 1.15-2.50), more diffuse somatic symptoms (OR = 2.38; 95 % CI, 1.61-3.51) and more musculoskeletal symptoms (OR = 1.21; 95 % CI, 1.13-1.29). Individuals still suffering from whiplash also visited more health practitioners at baseline (OR = 1.18; 95 % CI, 1.06-1.32) and used more medications (OR = 1.24; 95 % CI, 1.09-1.40).ConclusionPoor self-rated health seems to be a strong risk factor for whiplash injuries becoming chronic. Diffuse somatic symptoms, musculoskeletal symptoms and symptoms of anxiety at baseline are important prognostic risk factors. Knowledge of these maintaining risk factors enables identification of individuals at risk of non-recovery, facilitating adequate treatment for this vulnerable group.
