Seeking the Right Time for Venous Thromboembolism Prophylaxis Alerts.
Article in The Brown journal of hospital medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Our institution used an automated provider alert for venous thromboembolism (VTE) prophylaxis. This alert had an option to "snooze," generating a user-specific delay before repeat firing. Providers snoozed 67% of VTE alerts. Our aim was to decrease alert burden by 25% through lengthening the snooze delay. Methods: This initiative was conducted at a tertiary care academic medical center using an integrated electronic health record. Data was collected with snooze delay time set at 1, 2 and 3 hours. Our primary outcome was the number of alerts per 100 admissions. Secondary outcomes included percentage of alerts snoozed, percent of patients receiving pharmacoprophylaxis, and percent of admissions satisfying VTE core measures. Results: There was no change in alerts per 100 admissions (168 vs. 176, p=0.375) or percentage of patients receiving pharmacoprophylaxis (50.9% vs. 50.9%, p=0.997). There was a small reduction in snooze percentage (67.0% to 63.2%, p=<0.001) and a small increase in core measure satisfaction (86.0% to 88.0%, p=0.025). On post-hoc analysis, the intervention increased the median interval between same-patient, same-provider VTE alerts (3.4 to 8.3 hours). Internal medicine hospitalists were responsible for 22% of alerts, selecting snooze 78% of the time. Conclusion: Increasing snooze delay time did not decrease alert burden. Manipulating alert parameters is unlikely to decrease alert burden without simultaneous changes in provider response culture.
