Behavioral Economics to Improve Flu Vaccination Using EHR Nudges Replication
NCT06626321 · View on ClinicalTrials.gov ↗
Study Summary
This study will be a 6-month, cluster randomized, pragmatic replication trial to evaluate the effectiveness of personalized nudges to clinicians and patients, relative to a control, to increase flu vaccination rates among older adults in accordance with CDC guidelines. This will include clinician and patient level nudge interventions, with additional, intensified nudge interventions for patients identified as high risk for not receiving a flu vaccine. Among the intervention clinics, patients will receive pre-visit text message reminders about the flu vaccine, and clinicians will receive a default pended order in the visit encounter in the EHR, along with monthly peer comparison feedback about their flu vaccine completion rate. Patients identified as high risk for noncompletion will be individually randomized to receive an additional bidirectional text message nudge or the standard text messaging

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06626321
The ClinicalTrials.gov registry entry for NCT06626321 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 26,248 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Pennsylvania, which has 1,457 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Behavior, Health appearing as the primary indexed condition, and to 4 interventions — of which Pre-visit patient text messaging is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT06626321 reports 1 study location spanning 1 distinct geographic area — top geographies include Pennsylvania. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
