Safety considerations in the epilepsy monitoring unit for psychogenic nonepileptic seizures.

Injury occurs in epilepsy monitoring units (EMUs) to patients with epileptic seizures (ES); however, there are limited data regarding the safety concerns of patients with psychogenic nonepileptic seizures (PNES) being monitored in EMUs. We reviewed EMU records from 116 PNES and compared them to 170 ES. Three falls (2.6%) occurred in PNES without injury compared to 6 falls (3.5%) in ES with 1 injury, a facial hematoma. Of the 9 total falls, 8 patients were ambulatory during their events. Several adverse incidents occurred for both groups. Of the PNES without staff response, 30 of 39 were due to PNES being less than 60s in duration, and 16 of 39 involved lack of push-button activation to alert the staff. For the ES group, 57 of 101 were due to electrographic seizures without seizure detection software or push-button activation. Similar safety protocols should be administered while monitoring these patients regardless of seizure type.
