Costs of Inaccurate Anesthesia Start Time Documentation Within a Health System.

Inaccurate anesthesia start time (AST) documentation can result in lost revenue. Using a retrospective analysis, we estimated lost revenue from inaccurate documentation of the AST within a single health care system, including academic and community-based facilities. We used differences in nursing documentation of "in-room" time and AST to calculate lost billable revenue. Of the 282,432 cases included, 25.6% had a documented "in-room" time before the documented AST, resulting in an estimated loss of $703,522 within 30-month study period. Through educational interventions and feedback, anesthesia clinicians have the potential to significantly increase revenue through more accurate documentation of AST.
