Prevalence of Postpartum Depression Among Patients of the CHUM GARE Clinic

Postpartum depression (PPD) is a common complication in the weeks following childbirth, with potential consequences for maternal health and early infant development. Although validated tools such as the Edinburgh Postnatal Depression Scale (EPDS) exist, systematic screening is not uniformly integrated into routine postpartum care. This prospective observational study aims to evaluate the implementation of a structured protocol for the identification and referral of postpartum depression in a high-risk obstetric population. The study will include 100 postpartum patients followed at the high-risk pregnancy clinic of the CHUM. All participants will be systematically screened for symptoms of postpartum depression using the EPDS during their scheduled postpartum visit. For patients with a score of 13 or higher, medical orientation will be guided by a standardized clinical algorithm that defines the recommended follow-up. Two follow-up telephone calls will be conducted, at two weeks and six weeks after the initial screening, to confirm whether the recommended referrals have been completed and to evaluate the time required to access appropriate services. The primary objective of the study is to estimate the prevalence of postpartum depression in this population. The secondary objective is to assess the feasibility of implementing a systematic screening protocol combined with a clinical algorithm to guide referral and follow-up. The study also seeks to explore clinical characteristics associated with elevated EPDS scores, including age, level of education, lifestyle habits (smoking, alcohol or drug consumption), psychiatric, medical and obstetric history (including history of miscarriage), mode of delivery and method of perinatal analgesia, breastfeeding, iron-deficiency anemia or iron deficiency, obstetric, anesthetic, or neonatal complications and skin-to-skin contact in the delivery room within the first 24 hours after birth.
