Five-year trajectories of symptom severity, physical and mental functioning in patients with persistent somatic symptoms: the PROSPECTS cohort study

We identified distinct 5-year trajectories for the three outcomes. Our findings suggest a high prevalence of persistence of symptoms and limited improvement in physical and mental functioning in the majority of patients with PSS. In a small proportion of patients, we identified trajectories that showed considerable physical or mental improvement or deterioration. Patient characteristics differed for the identified trajectories and may guide early recognition, although predictive studies are warranted.
