Postpartum depression screening: are we doing a competent job?

Postpartum depression (PPD) is one of the most common and severe postpartum morbidity, affecting 10%-20% of mothers within the first year of childbirth. The adverse effects of PPD, namely, prevention of mother-baby bonding and early cessation of breastfeeding, adversely affects infant growth and brain development. Studies have found that up to 50% of women with PPD go undiagnosed. Despite the American Academy of Pediatrics (AAP) recommendations, only a small percentage of paediatricians are currently screening for PPD. This project aimed to improve PPD screening using a validated tool to 75% in a primary care inner-city clinic serving a predominantly underserved population as per AAP recommendations. Baseline data for 40 charts of 2-month-old and 4-month-old well-child visits showed no documentation of PPD screening. The screening tool used for this project was the Edinburgh Postpartum Depression Scale (EPDS), which is a validated 10-item screening questionnaire for PPD. Three Plan-Do-Study-Act (PDSA) cycles were implemented involving educational strategies, system-based practice improvement and stakeholder participation. Improvement seen after PDSA cycle 1 was minimal. At the end of cycle 2, 16/50 (33%) charts had documentation of screening using EPDS. At the end of cycle 3, 33/40 (82%) charts had EPDS documentation, an increase of 49% from cycle 2. There were eight in total positive PPD screenings between cycles 2 and 3. These patients were provided counselling support through a social worker and referral services through the local community mental health organisation. We achieved more than our 75% target goal for PPD screening implementation at the residency clinic, thereby increasing residents' awareness of PPD and the importance of PPD screening. Poststudy follow-up shows that screening was maintained at a higher rate but never reached 100%.
