Summary

This study looked at over 30,000 adults admitted to hospitals in Maryland to understand why some patients wait in the emergency room even after being admitted (called boarding). Researchers wanted to find out what patient traits lead to longer waits, how boarding increases healthcare costs, and whether high boarding affects care for all ER patients. The study used existing medical records and did not involve any new treatments.
