BACKGROUND: Studies of the accuracy and completeness of handwritten anesthesia records demonstrate deficiencies in documentation, suggesting that the quality of anesthesia records can be improved.

METHODS: We reviewed all electronic anesthesia records generated during a 1-month period at our institution to ascertain completion rates for six clinical documentation elements: allergies, IV access, electrocardiogram rhythm, ease of mask ventilation, laryngoscopic grade of view, and insertion depth of the endotracheal tube.

RESULTS: Of 2838 records, 64% had the necessary free text remark in the allergy element. The free text required to complete endotracheal tube depth documentation appeared in 538 of 918 cases in which the patient was tracheally intubated (59%). Free text documentation of the electrocardiogram rhythm diagnosis appeared at least once in 86% of records. Documentation of mask ventilation characteristics was entered by touch screen from a pick list and was expected in 781 records but appeared in 664 records (85%). Laryngoscopic grade of view documentation was also selected by touch screen and expected in 883 records but present in 811 cases (92%). Any notation of IV access appeared in 84% of records.

CONCLUSIONS: We found that electronic clinical anesthesia documentation was often incomplete. Dependence on free text remarks and the record keeping system’s inability to automatically present entries in logical sequences consistent with workflow were associated with incomplete data entry. Our results suggest that the user interface for data entry, and the logic that an electronic system uses for preventing omissions and inconsistencies, merit further study and development in order to facilitate clinically useful documentation.
