Ambulatory ICU Study for Medically and Socially Complex Patients

This is a prospective randomized wait-list control study to determine whether a stand-alone, co-located team of physician, mental health behaviorist, and care coordinators with decreased panel size (aka \"intensive primary care\") will reduce inpatient and emergency care utilization, inpatient costs of care, and improve patient activation and experience for medically and socially complex patients, compared to enhanced usual care at 6 and 12 months. Participants with multiple co-morbidities, and meet utilization criteria will have the opportunity to enroll; half the participants will start the intervention immediately, while half will continue enhanced usual care for 6 months before beginning the intervention.
