Strategies to Reduce Frequent Emergency Department Use among Persons Experiencing Homelessness with Mental Health Conditions: a Scoping Review.

The USA has some of the highest utilization rates of the Emergency Department (ED) worldwide, leading to increased healthcare costs, constrained resources, and fragmented care. Many of the highest ED utilizers are persons experiencing homelessness (PEH) and those with mental health conditions, with even higher use by those with comorbid social challenges. This study reviewed the literature assessing interventional approaches in the ED to minimize the burden of ED utilization by PEH with associated mental health conditions.
