Clinical and economic outcomes of a pilot project examining pharmacist-focused collaborative care treatment for depression.
OBJECTIVE
To assess the clinical and economic impact of a pharmacist-focused health management program for patients with depression.


METHODS
Prospective, nonrandomized, proof-of-concept investigation.


METHODS
Asheville, NC, from July 2006 through December 2007.


METHODS
Employees or adult dependents with depressive symptoms who agreed to enroll in an employer-sponsored treatment program conducted at two ambulatory clinics where consultative services were provided. Participants were included in the analysis if they participated in the program for at least 1 year and had two or more documented visits with a pharmacist.


METHODS
Outpatient-based pharmacists provided assessment, self-management services follow-up, and treatment recommendations to primary care providers within a collaborative care management model.


METHODS
Changes in severity of depressive symptoms and impact on overall health care costs for employers and beneficiaries.


RESULTS
Of the 151 beneficiaries referred to the program, 130 (82%) remained under pharmacist care for a minimum of 1 year and were included in the aggregate analysis. Statistically significant improvements were observed for Patient Health Questionnaire (PHQ)-9 scores from baseline to endpoint (11.5 ± 6.6 to 5.3 ± 4.7 [mean ± SD], P < 0.0001). The clinical response rate was 68% with a 56% remission rate. In economic subgroup analysis (n = 48), annual medical costs decreased from an average of $6,351 per enrollee to $5,876, which was lower than the projected value ($7,195). Total health care costs to the employer increased from $7,935 per enrollee to $8,040, which was lower than the projected value ($9,023).


CONCLUSIONS
Patients in the first year of the program had significant improvement in the PHQ-9 clinical indicator of depression severity. Total health care costs per patient per year were reduced compared with projected costs without the program. Employers expressed their appreciation for this collaborative care program and continued to offer this voluntary health benefit after the study's conclusion.
