Electronic health record interventions to reduce postoperative pregabalin prescribing: a quality improvement initiative.
Observational study in Canadian journal of anaesthesia = Journal canadien d'anesthesie, 2025. 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
purposePerioperative gabapentinoids may not provide meaningful analgesia and can have significant adverse events. Our objective was to estimate the association of two electronic health record (EHR) interventions with pregabalin prescribing by the acute pain service (APS) at a multi-site academic health sciences network.
methodsWe conducted a quality improvement initiative using a retrospective observational cohort and a quasi-experimental interrupted time series design. Following a baseline period (19 January 2021-19 January 2022), we introduced a Best Practice Advisory that warned of pregabalin's risks for sedation or respiratory depression. On 19 June 2022, pregabalin was removed as a standard checkbox in the APS orders. The primary outcome was the proportion of patients receiving pregabalin during their APS admission. The balancing measure was the highest postoperative day one pain score. Analysis used segmented regression in an interrupted time series design to estimate the immediate (level) change, trend (slope), and total counterfactual differences, controlling for the preintervention trend.
resultsWe included 10,667 patients (5,559 preintervention, 2,271 postintervention 1, and 2,837 postintervention 2). Preintervention, 1,284 APS admissions had a pregabalin order (23.1%) compared with 379 (16.7%) after intervention 1 and 490 (17.3%) after intervention 2. Our interrupted time series analysis did not identify significant immediate, trend, or total counterfactual differences associated with the interventions (intervention 1, total counterfactual P = 0.76; intervention 2, total counterfactual P = 0.11). Only the preintervention trend (-0.2% per week, 95% confidence interval, -0.5 to -0.1) was significantly different (P < 0.001). No changes in pain intensity scores occurred despite decreased pregabalin use over time.
conclusionWe did not identify a significant association of EHR interventions with pregabalin prescribing. Nevertheless, a continued downtrend in pregabalin prescribing was not associated with worsening acute pain.
