A Trial of Enhanced Versus Standard Measurement-Based Care Implementation for Depression

Overview

Measurement-based care (MBC) is an evidence-based practice that incorporates routine outcome assessment using validated rating scales to guide collaborative clinical decision-making. Although MBC results in improved outcomes for patients with major depressive disorder (MDD), there are barriers to its broad implementation in clinical settings. The use of "enhanced" MBC (eMBC), with mobile apps that allow patients to track outcomes and engage in self-management via WeChat, may address some of these barriers. This study intends to compare differences of efficacy between the implementation with eMBC using WeChat and the standard MBC implementation using paper-pencil assessments at the clinic, for both implementation and clinical outcomes.

Measurement-based care (MBC) is an evidence-based practice that incorporates routine outcome assessment using validated rating scales to guide collaborative clinical decision-making. Although MBC results in improved outcomes for patients with major depressive disorder (MDD), there are barriers to its broad implementation in clinical settings. The use of "enhanced" MBC (eMBC), with mobile apps that allow patients to track outcomes and engage in self-management via WeChat, may address some of these barriers. Therefore, we present a trial protocol for a 2-arm cluster randomized controlled trial (RCT) with a hybrid implementation-effectiveness design comparing standard MBC implementation versus eMBC implementation with 6-month follow up in 12 mental health centers in Shanghai, China. The eMBC implementation uses a WeChat mini-program that includes outcome tracking using brief questionnaires and self-management lessons supplemented with support by a lay coach via WeChat. The primary implementation outcome is implementation reach, defined as the proportion of eligible patients with a PHQ-9 score recorded in the hospital chart at 6 months after MBC implementation. The primary clinical outcome is clinical remission, defined as a PHQ-9 score of 4 or less at the 6-month follow up. Other implementation and clinical outcomes will be examined, including medication adherence, doctor-patient alliance, and a piggy-back cost-benefit economic analysis. Qualitative interviews will be conducted with physicians and patients to produce an interpretive account of the contextual factors which impact eMBC implementation. This study intends to compare differences of efficacy between the implementation with eMBC using WeChat and the standard MBC implementation using paper-pencil assessments at the clinic, for both implementation and clinical outcomes.
