Evaluation of provider response to positive depression screenings and physician attitudes on integrating psychiatric pharmacist services in primary care settings.

Introduction: The aim of this study was to identify potential gaps in the management of depression and assess the perceptions of primary care providers (PCPs) toward integrating psychiatric pharmacists into primary care settings.

Method: This was a retrospective chart review of patients ≥18 years of age seen in primary care clinics in Los Angeles County with a documented annual health screening (AHS) between January 1, 2015, through December 31, 2015. Primary outcomes were number and percentage of patients screened for depression with patient health questionnaire (PHQ) assessments, positive depression screenings, and interventions made for positive depression screenings. Secondary outcomes were PCPs' perceptions on management of depression, use of AHS, and roles for psychiatric pharmacists through evaluation of provider survey.

Results: Of the patients who received an AHS (n = 6797), 63% received PHQ assessments. Of 145 individuals with a positive PHQ-2, 69% had a positive PHQ-9. Greater than 50% of individuals with a positive PHQ-9 had no preexisting depression diagnosis. Seventy-six percent of individuals with a positive PHQ-9 and 78% with reported suicide ideation had no documented intervention. The majority of providers reported there is a role for psychiatric pharmacists in primary care.

Discussion: Gaps in the management of depression were identified. Although depression screenings were performed for the majority of individuals receiving an AHS, no documented interventions were made for most of those individuals who screened positive for depression. Primary care clinics could benefit from psychiatric pharmacist involvement in depression screening and follow-up processes.
