简要总结
Major depressive disorder (MDD) is one of the leading causes of disability worldwide, indicated as one of the two most disabling mental disorders by the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 (Vos et al., 2020). Despite several effective pharmacological and psychosocial interventions available globally, only about one-third of depressed patients achieve remission (Xiao et al., 2021). There is a need to establish scalable clinical management practices which utilize biopsychosocial assessments, formulate a differential diagnosis, and provide evidence-based treatments for patients with MDD (Hong et al., 2021). While significant evidence for effectiveness of Measurement Based Care (MBC) is found in clinical settings from high and middle-income countries, assessments of MBC compared with usual care for the treatment of MDD are yet to be completed in low-resource settings like LMICs. The aim of this trial is to determine the efficacy and safety of MBC in patients with MDD in comparison with standard care in Pakistan. In order to reduce the variance found in treatment-as-usual and isolate the impact of MBC, standard care for this trial will limit medication choices to either paroxetine or mirtazapine.
详细描述
Hypothesis
The rates of response and remission, and time to response and remission would be significantly shorter in the MBC group, without greater dropout rates and side effect burden, compared with the standard treatment group.
Study design and setting This will be a multi-centre, with assessors blind to protocol and treatment group, parallel arm, randomized controlled trial (RCT). The study is a direct replication of a study conducted by Gou et al. (2015) in China.
Participants Participants will be recruited from psychiatric units of teaching and non-teaching hospitals in 6 centres: Karachi (population 23 million), Lahore (population 10 million), Rawalpindi (population 3 million), Hyderabad (population 2 million) and Quetta (population 1 million) and Multan (1.8 million).
Sample size The sample size of 120 participants for this exploratory trial is based on the study conducted by Guo et al.

盲法说明
This will be an assessor blind, randomized controlled trial. Due to the nature of the interventions, it will be impossible to blind clinicians in participating centres or the participants themselves. Before assessments, participants will be asked not to reveal any information about treatment to assessors. To avoid unblinding, outcome assessors will be located separately from treatment providers, and we will assign new outcome assessors in cases of unintentional unblinding.

结局指标
主要结局
Hamilton Depression Rating (HDRS-17) - Time to Response
时间窗: Time from baseline to response (in weeks) (assessed upto 24 weeks).
is a 17-item instrument that was designed to measure frequency and intensity of depressive symptoms in individuals with major depressive disorder. Ratings are made using either a five- or a three-point scale, yielding total scores from zero to 61. Response will be defined as a decrease of 50% from the baseline HDRS-17 score.
Hamilton Depression Rating (HDRS-17) - Time to Remission
时间窗: Time from baseline to remission (in weeks) (assessed upto 24 weeks)
is a 17-item instrument that was designed to measure frequency and intensity of depressive symptoms in individuals with major depressive disorder. Ratings are made using either a five- or a three-point scale, yielding total scores from zero to 61. Remission as a HDRS-17 score\<7
次要结局
- Hamilton Depression Rating (HDRS-17) - Severity(Change in scores from baseline to 3-month and 6-month follow up)
- Adverse Effect Checklist(Rates of adverse effects from baseline to 6-month follow up)
- All-cause discontinuation(Time from baseline to all-cause discontinuation of antidepressant medication (assessed upto 24 weeks))
