Scaling Up Maternal Mental Healthcare by Increasing Access to Treatment (SUMMIT)

SUMMIT's (Scaling Up Maternal Mental health care by Increasing access to Treatment) overarching goal is to examine the scalability and patient-centered provision of brief, evidence-based psychological treatments for perinatal depression and anxiety (N=1226). Specifically, and through a multi-site, randomized, pragmatic trial, the trial examines whether a brief, behavioral activation (BA) treatment delivered via telemedicine is as effective as the same treatment delivered in person; and whether BA delivered by non-mental health providers (e.g., nurses), with appropriate training is as effective as when delivered by specialist providers (psychiatrists, psychologists and social workers) in reducing perinatal depressive and anxiety symptoms. The study will be conducted in Toronto, NorthShore University HealthSystem in Evanston and surrounding areas including Chicago, and North Carolina. The trial will also identify relevant underlying implementation processes and determine whether, and to what extent, these strategies work differentially for certain women over others.

Eligible participants are randomly assigned to the same BA treatment for perinatal depressive and anxiety symptoms in one of four arms: 1) In-person specialist; 2) Telemedicine specialist; 3) In-person non-specialist; 4) Telemedicine non-specialist. However, due to the COVID-19 pandemic, recruitment was adjusted as below: 1. March 2020-July 2021: For the duration of the COVID-19 pandemic period participants were only randomized 1:1 to 1) Telemedicine non-specialist; 2) Telemedicine specialist. 2. July 2021 to January 2022: Randomization of participants to all 4 arms resumed, using a raking approach (weight ratio of 3:1 favoring In-Person to Telemedicine), to rebalance the arms. 3. January 2022 to April 2022: In light of the COVID-19 Omicron variant, participants were only randomized 1:1 to 1) Telemedicine non-specialist; 2) Telemedicine specialist. 4. April 2022 to present: Randomization of participants to all 4 arms resumed at all sites (ratio 1:1:1:1) to 1) In-person specialist; 2) Telemedicine specialist; 3) In-person non-specialist; 4) Telemedicine non-specialist. Randomization to all 4 arms will be followed until in-person arms are fully enrolled after which randomization 1:1 to the two telemedicine arms will be followed. A flexible study design was established at each site based on site-specific COVID restrictions. This approach was verified by the study statistician, an independent methodologist and the study funder. All analyses will be run as both intent-to-treat and per protocol.
