CDS Intervention
RECRUITMENT
We devised an innovative approach that enabled us to conduct a cost-effective national study to validate the findings of our pilot study comprising RNs from a large Midwest US metropolitan area [The first year of the study was spent reprogramming and iteratively testing the new web-based version of the intervention. Reprogramming was performed by our team programmer and initial testing was conducted by the team. In the final phase of development, the entire procedure for accessing, orienting, and interacting with the intervention was pretested with a sample of 31 RNs (10 from our initial study recruitment cycles and 21 from a convenience sample). This ensured that the intervention operated as intended for a broad range of user setups (internet and computer), enabling a diverse set of RNs to participate from their homes.The intervention, described in detail elsewhere [The hypothetical patient scenarios were developed by the investigators (DW and GK) using real patient histories and simulating realistic patient trajectories across time. The CDS recommendations in the study were based on evidence generated by our research team on previous data collected with HANDS under real-time conditions and peer-reviewed literature. An example of Mr Taylor’s history (a hypothetical patient in the study) is shown in Intervention clinical decision support formats assigned to registered nurse participants: (A) text format, (B) table + text format, and (C) graph + text format.
