“…Several factors affect LOS in ED patients, including organizational factors (such as shortage of beds leading to hospital transfer, radiological imaging, or sequential specialist consultations), as well as patient and hospital-specific factors (such as patient age, hospital teaching status, hospital size, and delayed ED throughput of trauma patients) [18][19]. Additionally, Salehi et al demonstrated that patients under isolation, under telemetry, older patients, and patients with a greater comorbidity burden had prolonged waits in the ED (either as prolonged ED LOS or prolonged boarding) and these prolonged boarding times were associated with greater inpatient LOS [20]. Importantly, ED boarding contributes to the increased morbidity and mortality of trauma patients by delaying the initiation of trauma ICU (TICU)-specific care protocols, which drive the trauma care outcomes, especially during initial resuscitation efforts [4].…”
