Objective
The objective is to describe the effect of medical and psychiatric comorbidities on receipt of guideline-concordant depression care.
Methods
2003-6 pharmacy, medical and behavioral claims and enrollment data from OptumHealth were linked for 1,835 adults with a new depression diagnosis or antidepressant fill. Multiple logistic regression was used to estimate the association of comorbidities with receipt of guideline-concordant pharmacotherapy, psychotherapy, and any therapy.
Results
Respectively 11%, 23% and 33% of study patients received guideline-concordant psychotherapy, pharmacotherapy and any therapy. Having a psychiatric but no medical comorbidity was associated with higher rates of guideline-concordant psychotherapy and overall guideline concordance; the converse was true for having a medical but no psychiatric comorbidity. Associations of comorbidities were with the probability of receiving any therapy, not improved guideline-concordance among patients already receiving therapy.
Conclusions
Patients with medical comorbidities may not receive psychotherapy referrals, perhaps due to well-established relationships with their primary care providers.
