Evaluation of Best Practice Alerts and an Actionable Sidebar in Electronic Health Records in Promoting Bone Densitometry Scans

Standard care for bone densitometry scans at Geisinger--i.e., dual-energy x-ray absorptiometry (DXA) scans--involves (1) an alert under the health maintenance topics tab in Epic, (2) an actionable item in a sidebar (Storyboard), (3) and a single-click best practice alert (BPA). Storyboard and the BPA theoretically serve a redundant function, but it is possible that combined alerting is effective. Therefore, the investigators plan to evaluate whether the BPA for DXA scans will increase the percentage of DXA scans ordered and completed.

For this evaluation, the investigators will randomly assign (by odd and even MRN) half of patients who need DXA scans to go through standard care (including the single-click BPA) and half of patients to have no BPA shown to their provider, but only the health maintenance topic and actionable Storyboard alert. This evaluation will help the investigators determine whether redundant, more traditional alerts such as BPAs are helpful or can be removed from alerts for DXA scans.

The randomization of patients to different alert conditions will be in place until 4,200 participants have been reached (estimated sample to detect 4% absolute difference, rounded to nearest hundred) or 6 months, whichever comes first. To account for delays in updating clinical databases, the outcome data will pulled 3 months after each encounter (for a maximum study period of 9 months).

The main analysis will use a logistic regression to compare the two groups. Exploratory analyses will also examine the time from order to completion to examine any effect on timing between arms. Another set of exploratory analyses will also examine the number of other BPAs firing to see if alert fatigue influenced the number of orders or completions or interacted with the experimental conditions.
