Automated Anesthesia Recordkeeping (AARK) has been available for over 20 years and is being used in more and more operating rooms across America and around the world.   Despite becoming mainstream technology, AARK continues to generate controversy.   Is the advantage of automatic physiologic data capture offset by a loss of vigilence by the anesthesia provider?  Several studies have investigated the loss of vigilence related to AARK.

J. Allard, R, D. Zwoncaky et al published the results of a study in the British Journal of Anaesthesia addressing the issue of the effects of AARK on provider vigilence.

As stated by the Authors: “Proponents of this technology profess that automated record keepers reduce record keeping time thereby leaving more time for data interpretation and patient care . Moreover, others suggest that computer-generated records are more accurate and complete than those charted manually . On the other hand, critics argue that allowing the AARK to chart the vital signs removes the anesthetist from the information feedback loop and thereby has an adverse effect on vigilance . The main intent of this study was to determine the effect of an AARK on intraoperative record keeping time and vigilance.”

“Thirty-seven cases were charted manually and the remaining 29 were charted with a commercially available AARK. In order to evaluate vigilance, a physician examiner entered the operating room unannounced once during 33 of the manually charted cases and during 22 of the automatically charted cases and asked the anesthetist to turn away from the monitors and recall the current value of eight patient physiological variables. The examiner recorded the recalled values and also the actual current monitor values of these variables. The videotapes were reviewed and the anesthetist’s intraoperative time was categorized into 15 predefined activities, including intraoperative anesthesia record keeping time. We compared recalled and actual variable values to determine if the recalled values were within clinically relevant error limits.”

The authors conclude the use of the AARK did not significantly affect vigilance.  They go on to state that it appears that in using an AARK, the provider reallocates intraoperative record keeping time from manual charting to dealing with problems.
