Randomised trial comparing the recording ability of a novel , electronic emergency documentation system with the AHA paper cardiac arrest record . OBJECTIVE To evaluate the ability of an electronic system created at the University of Washington to accurately document prerecorded VF and pulseless electrical activity ( PEA ) cardiac arrest scenarios compared with the American Heart Association paper cardiac arrest record . METHODS 16 anaesthesiology residents were randomly assigned to view one of two prerecorded , simulated VF and PEA scenarios and asked to document the event with either the paper or electronic system . Each subject then repeated the process with the other video and documentation method . Five types of documentation errors were defined : ( 1 ) omission , ( 2 ) specification , ( 3 ) timing , ( 4 ) commission and ( 5 ) noise . The mean difference in errors between the paper and electronic methods was analysed using a single factor repeated measures ANOVA model . RESULTS Compared with paper records , the electronic system omitted 6.3 fewer events ( 95 % CI -10.1 to -2.5 , p=0.003 ) , which represents a 28 % reduction in omission errors . Users recorded 2.9 fewer noise items ( 95 % CI -5.3 to -0.6 , p=0.003 ) when compared with paper , representing a 36 % decrease in redundant or irrelevant information . The rate of timing ( Δ=-3.2 , 95 % CI -9.3 to 3.0 , p=0.286 ) and commission ( Δ=-4.4 , 95 % CI -9.4 to 0.5 , p=0.075 ) errors were similar between the electronic system and paper , while the rate of specification errors were about a third lower for the electronic system when compared with the paper record ( Δ=-3.2 , 95 % CI -6.3 to -0.2 , p=0.037 ) . CONCLUSIONS Compared with paper documentation , documentation with the electronic system captured 24 % more critical information during a simulated medical emergency without loss in data quality .
