This is a two-armed randomized study of patients with chronic cardiopulmonary diseases in three levels of health literacy. Patients will be tested with the 66 word version of the Rapid Estimate of Adult Literacy in Medicine (REALM) test to allow us to analyze the data according to literacy categories ( 6th grade, 7th-8th grade, and 9th grade). Patients will be randomized to one of the following groups: 1) standard discharge (control group); 2) a experimental group receiving both the case management intervention plus educational and self-management support by Embodied Conversational Agents (ECAs) and post-discharge reinforcement of the discharge plan using a computerized telephone system
