Past Research and Future Directions

RECRUITMENT
As noted earlier, reports of unintended consequences from poor design and inadequate testing [Building on our pilot findings, we set out to determine whether tailoring assignment to a CDS format by GL would further improve the documentation time and the potential quality of care plans (eg, adoption rates of evidence-based CDS recommendations) in a national RCT of 203 RNs. We purposefully sought to ensure that our findings would represent the diversity of RNs in the United States employed in hospital medical-surgical units. To do this, we implemented an innovative recruitment method and deployment of our intervention. We used 10 SBON lists to randomly identify RNs eligible for our study (Although our RCT hypotheses were not supported, this study replicated our previous findings that low GL was associated with higher CPT in the TG condition. The robustness of these associations, given the high quality of our sample, suggests the need to consider the GL of RNs when designing and integrating visual displays such as graphs into care planning CDS. Our findings are supported by others who also found an association between higher GL and reduced decision time [In summary, although our hypotheses did not hold, the results of this study offer important knowledge for future directions. Our findings suggest a clear need for further research to establish the combination of factors to consider when using visual displays in the EHRs for specified purposes. Although others have examined clinician format preferences and the relationship of visual display type to the accuracy of some types of data, research has yet to establish the conditions (eg, setting, clinician characteristics, data types, and purpose of use) that collectively affect the achievement of desired outcomes. Although our tailoring scheme did not reduce RN documentation time for care planning, we confirmed the relationship between GL and documentation time in our pilot study. In the future, we will continue using our innovative preclinical recruitment and national testing methods to further isolate the factors [
