The investigators propose a pilot randomized controlled trial of a care transitions intervention in which trained Community Health Workers will act as supports for socioeconomically vulnerable patients who are being discharged from the Hospital of the University of Pennsylvania and Presbyterian Hospital. CHWs or IMPaCT Partners will help patients to overcome the challenges of transition, including arranging primary care provider (PCP) follow-up, filling medication prescriptions and obtaining referrals to community-based social services. As our primary outcome, the investigators will examine the effect of the IMPaCT intervention on rates of primary care follow-up. The investigators will also examine the effect of IMPaCT on secondary outcome variables including patients' satisfaction with the experience of transition, quality of discharge communication, medication adherence, self- rated health, and inpatient readmission within 30 days after discharge.
