Lunacy.

To assess the moon's perceived impact on emergency medicine, a survey was conducted using a modified Belief in Lunar Effects (BILE) scale. Eighty percent of the respondent emergency department nurses and 64% of the emergency physicians believe that the moon affects patients. Of these nurses, 92% find lunar shifts more stressful and indicated lunar pay differentials are warranted. Medical, social, and administrative strategies to deal with lunacy are presented.
