Abstract
PURPOSE: Nonbenzodiazepine sedation (eg, dexmedetomidine or propofol) may be more cost effective than benzodiazepine (BZ) sedation despite its higher acquisition cost.
MATERIALS AND METHODS: A cost effectiveness (CE) analysis of noncardiac surgery, critically ill adults requiring at least 1 day of mechanical ventilation (MV) and administered either BZ or non-BZ sedation, that cycled health states and costs daily using a Markov model accounting for daily MV use until intensive care unit (ICU) discharge, was conducted from a third-party perspective. Transition probabilities were obtained from a published meta-analysis, and costs were estimated from best evidence. Sensitivity analyses were run for all extubation and discharge probabilities, for different cost estimates and for the specific non-BZ administered.
RESULTS: When non-BZ rather than BZ sedation was used, the incremental cost-effectiveness ratio to avert 1 ICU day while MV or while either MV or non-MV was $3406 and $3136, respectively. The base-case analysis revealed that non-BZ sedation (vs BZ sedation) resulted in higher drug costs ($1327 vs $65) but lower total ICU costs (percent accounted for MV need): $35380 (71.0%) vs $45394 (70.6%). Sensitivity analysis revealed that BZ sedation would only be less costly if the daily rate of extubation was at least 16%, and the daily rate of ICU discharge without MV was at least 77%. The incremental CE ratio to avert 1 ICU day while MV or non-MV was similar between the dexmedetomidine and propofol non-BZ options.
CONCLUSIONS: Among MV adults, non-BZ sedation has a more favorable CE ratio than BZ sedation over most cost estimates.
