Developing a culture of safety in the epilepsy monitoring unit: a retrospective study of safety outcomes.

This study retrospectively reviewed 971 consecutive admissions to our epilepsy monitoring unit (EMU) from July 2007 to May 2011 to compare falls and missed seizures before and after implementing stricter safety processes in May 2009. New safety processes included enhanced staff education, a falls prevention signed contract with patient/family, observation of video-EEG monitors only by EEG technologists, hourly nurse rounding, standby assistance for hygiene needs, and immediate review of adverse events. Wilcoxon's two-sample tests were used for statistical analysis of the two groups. Reduced events between pre-intervention (492 patients) and post-intervention (479 patients) were significant for missed seizures (26 pre- vs 6 post-intervention, p=0.009) but not for falls (12 pre- vs 7 post-intervention, p=0.694). Intensive safety efforts in the EMU produced a 15% reduction in the fall rate per 1000 patient days and a 77% decrease in missed seizures. This study shows stricter safety processes help improve EMU patient safety.
