BackgroundThe primary aim of this study was to determine the period prevalence of the single-syringe ketamine-propofol admixture used for sedation and induction among anesthesia providers during a 5-year period before and after educational sessions addressing barriers to its use. Secondary aims were to determine barriers to its use and address the most prevalent concerns through educational sessions.Material And MethodsSurveys were administered to certified and student registered nurse anesthetists, anesthesia residents, and anesthesiologists at Mayo Clinic Rochester, MN before and after educational sessions addressing common barriers. Identified barriers were addressed by oral and/or electronic presentations with identical content.ResultsPre-education period prevalence for sedation was 110 (43%) and 64 (25%) for induction. Identified barriers were uncertainty of benefit in 62 respondents (23%), mixed controlled substance disposal in 48 (18%), regulatory/institutional policies in 20 (7%), and compatibility in 9 (3%). Post-education period prevalence for sedation was 102 (44%), and induction 63 (27%). No concerns were noted in 72% of the post-education group verses 42% in the pre-education group (p<0.01). No concerns were reported in 51% of the electronic only education group verses 64% in the oral education group (p<0.01).Conclusions The period prevalence of "ketofol" was greater for sedation than induction. The period prevalence following education showed a slight increase in both sedation and induction use. There was a significant reduction in barriers following education, with oral presentations being more effective than electronic only. Period prevalence was increasing following education; however, allowing more time may have shown a significant practice change.
