Despite the high cost and prevalence of depression, it is often either undiagnosed or not diagnosed in a timely manner, and diagnosis does not always lead to treatment. While the costs of depression after the diagnosis of the condition have been widely studied, literature on the healthcare costs and absence-from-work costs during the period between initial disease onset and subsequent diagnosis and treatment is not as robust.
The purpose of this research is to estimate the excess healthcare costs and absence-from-work costs during the two-year period prior to the initial diagnosis of depression. We estimate that the total excess healthcare costs and absence-from-work costs for persons with undiagnosed depression over the two-year period leading up to the depression diagnosis/treatment is approximately $3,386 per undiagnosed depressed individual (in 2009 dollars).
