A national sample of anesthesia records were studied prospectively for the presence or absence of predetermined, noteworthy record indicators judged important in documenting a basic core of information describing the monitoring and care provided in a generic clinical setting. Only records involving the administration of a volatile anesthetic for the purpose of achieving general anesthesia, prepared by providers with at least 6 months of experience in anesthesia care were examined. No identifying patient, provider, or institutional data were recorded. Indicators were scored in a "present/absent" format. All data were pooled; the goal was to describe the overall phenomena in terms of frequency of compliance. A total of 4,989 anesthesia records were evaluated in terms of 13 record indicators. Those missed ranged from 0.0% (patient identification) to 28.6% (notation regarding emergence). Ten were omitted on less than 6% of the records: 3 (surgery and/or anesthesia start time, notation regarding emergence, surgical positioning noted) were omitted on more han 13.0% of the records. Given he observed inconsistencies, perhaps the anesthesia record needs redesign or the rationale behind documentation requires increased emphasis in educational and equally assurance programs.
