Details and examples of the MSE are described in Expansion of the Definition of MSE . In most of the country, the emergency physician is designated to perform the MSE and should take appropriate history and perform an appropriate physical examination. Patients with actual or occult EMCs will need further laboratory studies and or treatment. Nurses who provide MSEs must determine if an emergency medical condition exists and follow protocols approved by the hospital governing body.
Protocols typically are strict and complex and require rigorous training of the nursing staff.
The MSE must not be delayed. HCFA has cited some EDs in which patients have waited extended times prior to ED evaluation. See Prudent Layperson Definition of Emergency Medical Condition . Stabilization entitlement for treatment of emergency medical conditions Federal law requires that all patients with EMCs be stabilized within the capacity of the institution. Patients must be stabilized regardless of ability to pay.
