Combining Data Sources to Identify Effect Moderation for Personalized Mental Health
Study Details
Study Description
Brief Summary
This work will extend and apply methods for modeling heterogeneous treatment effects when multiple studies are available, with a particular focus on the complexities in mental health research. The methods will be illustrated in examples estimating the effects of medical treatments for major depressive disorder (duloxetine and vortioxetine) using 4 randomized controlled trials (available in the Vivli trials resource) and non-experimental data from the Duke University Health System electronic health record and the Johns Hopkins Health System electronic health record systems.

Outcome Measures
Primary Outcome Measures
- 9-question Patient Health Questionnaire (PHQ-9) or PHQ-2 scores [6 months]
Higher score indicates greater severity of major depressive disorder.
- 9-question Patient Health Questionnaire (PHQ-9) or PHQ-2 scores [1 year]
Higher score indicates greater severity of major depressive disorder.
Secondary Outcome Measures
- Emergency room visits or inpatient admissions with diagnosis of depression or suicidality [6 months]
A binary outcome equals to 'Yes' if the patient ever had any emergency department or inpatient hospital admission encounter with depression or suicidality International Classification of Diseases (ICD) codes, otherwise equals to "No".
- Emergency room visits or inpatient admissions with diagnosis of depression or suicidality [1 year]
A binary outcome equals to 'Yes' if the patient ever had any emergency department or inpatient hospital admission encounter with depression or suicidality International Classification of Diseases (ICD) codes, otherwise equals to "No".
- Emergency room visits or inpatient admissions for any reason [6 months]
A binary outcome equals to 'Yes' if the patient ever had any emergency department or inpatient hospital admission encounter after the prescription, otherwise equals to "No".
- Emergency room visits or inpatient admissions for any reason [1 year]
A binary outcome equals to 'Yes' if the patient ever had any emergency department or inpatient hospital admission encounter after the prescription, otherwise equals to "No".
