  • * Each event is reported as a percent of the total number of patients in that category (n = 95 for entire cohort: for 24 the venue was unknown, 43 were hospital-based, and 28 were nonhospital-based events). Note that there was a higher incidence of cardiac arrest as the secondary and tertiary event in the nonhospital-based facilities; some patients only had 1 event.

  • P < .001 compared with hospital-based adverse sedation events.
