Data Plan: H1 Depression Treatment : Patients of CAREPATH home nurses with clinically significant depressive symptoms will be more likely to receive a "guideline-based step" in their treatment of depression than patients of nurses providing usual care. This analysis will be tested using the merged administrative data set. A mixed-effects logistic regression analyses will compare patients in the intervention and usual care groups on change in depression treatment received. The primary independent variable (a fixed effect) is group and the dependent variable is change (from start-of-care to discharge to guideline consistent treatment received (yes/no). The structure of these data from this cluster randomized trial involves three level mixed-effects models in which patients are nested within nurse and nurse within team supervisor. These analyses will be preceded by mixed-effects models that compare groups on sociodemographic and clinical variables. Those variables that differ significantly will be included as covariates in the primary analysis that examines the intervention effect (described above).
