Objective: The purpose of this study was to assess the accuracy of a Web-based resuscitation recording program compared with the handwritten method. Methods: A Web site was developed to record in-hospital resuscitation events and a mock resuscitation was recorded using both the Web site and handwritten method by emergency nurses. Accurate recorded events and times were compared between the two methods through the use of a video clip. Paired t tests were used to compare differences in absolute timing error, the number of omitted events out of 11 reference events and total recorded events. Results: Twenty-one emergency nurses recorded simulated resuscitation events using both the handwritten and Web-based computerised recording system. The mean absolute timing errors were significantly lower using the computerised recording program (37.3 s (SD 17.1) versus 8.3 s (SD 5.3), pConclusions: This study suggests that a Web-based recording program decreased timing error while causing no differences in the number of recorded or omitted events in a laboratory setting.
