Overview
TG
In the current national RCT with 203 hospital RNs, we found that our hypotheses were not supported. We expected the tailored CDS group to outperform the nontailored CDS groups on time spent on care planning and adoption of CDS evidence-based recommendations, but this did not occur. Our exploratory analysis found that comfort working with EHR was associated with less time spent on care planning. Older age and lower GL were associated with longer decision time when evidence was presented in a TG format, whereas such associations did not hold when evidence was presented in a TO or TT format. There were also no significant differences found across groups when comparing the RNs’ perceived cognitive workload of using the assigned CDS. Perhaps the most important outcome, however, is that this study demonstrated the feasibility of an innovative approach for conducting a national RCT on a prototype EHR component via the internet. This success provides a viable approach for pretesting EHR components before integration into practice with truly diverse representative samples of potential users under simulated conditions, thereby avoiding unintended risks to patients.
