TLC-C is a modification of an existing TLC-Multi-Disease system that targets patients with multiple chronic diseases combined with a post-hospital discharge intervention (TLC-RED-Lit). TLC-C uses conversational computer telephony to monitor patients' multiple diseases between their ambulatory care visits. The system works in both routine (patient stable) and exacerbation (patient unstable) modes. The system monitors patients through "virtual visits" and detects and notifies clinicians about important clinical problems to attend to. It also promotes patient self-care (e.g., medication adherence and appointment preparation). In emergent situations the system recommends going to the local Emergency Department (ED). In urgent situations, an alert is sent to the clinician or to his/her coverage provider. Exacerbation mode is used when the patient is discharged from a hospital inpatient service or ED or has worsening symptoms. It concentrates on the exacerbating disease and monitors patient status (improved, stable or deteriorating). Daily contact is maintained until the patient's status improves. Routine mode occurs with the patient at their baseline status and monitors the disease and the patients' self-care behaviors.
