Impact of an on-site perinatal mood disorders clinic in the diagnosis and management of perinatal mood disorders.

Objectives To assess change in Edinburgh Postnatal Depression Scale (EPDS) scores in women treated at the Perinatal Mood Disorders Clinic (PMDC) as a measure of improvement in perinatal mood disorders (primary outcome), and treatment disposition at final visit. Methods Chart review was performed for all PMDC patients between March 1, 2017 and June 1, 2018 (n=120), as a self-controlled case series design. Two-tailed t-tests compared initial and final EPDS scores for all patients with >1 visit (n=64), where EPDS score of ≥13 indicated a positive screen for depression. A multivariable linear regression model with robust standard errors estimated the relationship between patient characteristics and final EPDS scores. Results Of 120 patients, n=56 had one visit and n=64 had >1 visit. Of these 64, mean final score (11.04) was lower than mean initial score (16.54; p<0.001). Additionally, certain patient characteristics were associated with higher final EPDS score, including history of mood disorder and treatment with both pharmacotherapy and psychotherapy. Conclusions Women treated at the PMDC showed improved EPDS scores when receiving at least two separate care visits. Therefore, the clinic may be filling a gap in access to timely care for women with perinatal mood disorders.
