MedicalResearch.com: What is the background for this study? What are the main findings?
Response: There is great variation among patients with depression in terms of long-term illness course. This variation may be indicative of underlying differences in the cause of the illness, and from a practical perspective, it also has implications for treatment and allocation of public health resources. Our goal was to identify different trajectories of depression course by examining inpatient and outpatient contacts for depression at psychiatric treatment facilities in Denmark (where healthcare is free) during the 10-year period following patients’ initial depression diagnosis.
We found that the majority of patients (77% in our sample) followed a trajectory characterized by a brief period of contact with the psychiatric treatment system and no contact for depression during the remainder of the 10-year follow up period. Patients with more prolonged contact either had a drawn out initial period of contact lasting as long as five years (13%), left depression treatment for several years only to return with a depression diagnosis years later (7%) or exhibited a chronic course (3%).
