The project will involve: (1) screening patients for depression, generalized anxiety disorder, and panic disorder as part of usual clinical care, (2) evaluation of positive-screen patients by a study social work care manager, (3) a multicomponent in-hospital intervention (for collaborative care patients) that involves patient education, specialist-provided treatment recommendations, and a goal of in-hospital treatment initiation, and (4), after discharge, continued phone-based evaluation and care coordination with primary care physicians to provide stepwise treatment in the collaborative care arm. The intervention has been designed to be low-cost, low-burden, and easily generalizable to other settings.
