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.
