An audit into the reasons why treatment was not completed as planned under intravenous sedation in an adult oral surgery department, and the cost implications.

This audit aimed to identify the prevalence of, and reasons for failed intravenous conscious sedation in an adult oral surgery department, to develop recommendations to reduce such failures and to identify any cost implications. Data were collected prospectively for three months for all intravenous sedation appointments in the Oral Surgery department. Data were collected for 109 sedation appointments of which 83 were successful (76%). The failure rate (24%) was higher than the acceptable departmental failure rate (10%), and included reasons for failure that should have been avoided by a thorough patient assessment prior to treatment. Of the 26 failures, the most common reasons for failure were: cancellation: 8 patients (30.8%), failure to attend: 6 patients (23.1%), excessively late arrival of patient: 4 patients (15.4%) and failure to cannulate: 3 patients (11.6%). When sedation was unsuccessful, 13 of the 26 patients (50%) had their treatment successfully completed under local anaesthesia alone, 10 patients (38%) were rebooked for sedation and 3 patient. (12%) were rebooked for a general anaesthetic. Identifying and correcting the reasons for failure can result in vast savings in appointment time, clinical resources and cost. That 13 patients subsequently had their treatment completed under local anaesthesia alone opens the debate on how rigorous the patient assessment and allocation of sedation appointments was, and the potential to achieve savings.
