Emergency Department Linkage to Care for Patients Experiencing Homelessness

Patients who experience homelessness frequently utilize the ED, but lack follow up primary care. In an effort to augment access to post-ED primary care, the investigators propose a quasi-experimental equivalent time sample study in which patients fitting certain diagnostic and inclusion criteria are allocated to either a) a referral to the Comprehensive Care Clinic at Denver Health, or b) a referral to Colorado Coalition for the Homeless (CCH) Stout Street medicine clinic. The street medicine clinic aims to lower barriers to access by locating patients on the street and providing primary care rather than asking patients to present to clinic. All patients will still receive the hospital appointment line number at time of discharge. 1 month and 3 months after index visit, the investigators will examine follow up rates at both clinics as well as secondary outcomes including ED visits, hospitalizations, and mortality through chart review of Denver Health and CCH electronic health records and CORHIO.
