Pharmacotherapeutic actions related to drug interaction alerts - a questionnaire study among Swedish hospital interns and residents in family medicine.
Article in European journal of clinical pharmacology, 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
purposeTo explore how hospital interns and residents specialising in family medicine act on drug interaction alerts in a specific patient case, and on interaction alerts in general.
methodsA 4-page questionnaire, including a fictional patient case (73-year-old woman; 10 drugs in the medication list triggering 11 drug interaction alerts) and questions regarding the use of interaction alerts in general, was distributed to interns and residents during educational sessions (November‒December 2023). The respondents were instructed to consider what actions they would take "a normal day at work" due to the risk of interactions between the patients' drugs. In the general questions, the respondents were asked how often they access the detailed interaction information (from 1 = never to 5 = always) provided by the knowledge resource, in relation to the alert classification (D = clinically significant, should be avoided; C = clinically significant, can be handled by, e.g., dose adjustment).
resultsThe questionnaire was completed by 55 interns and 69 residents (response rate: 98%). In the patient case, the respondents acted on a median of 4 (range: 0‒8) drugs, most often concerning repaglinide (in a D interaction alert with clopidogrel; 96% of the interns and 96% of the residents suggested action), and omeprazole (in three C interaction alerts with citalopram, clopidogrel, and levothyroxine, respectively; 71% and 83% suggested action). Among the respondents who answered the questions about how often (rated 4/5) they access more detailed information about interactions, 56 (59%) did so for D versus 29 (31%) for C alerts (P < 0.001).
conclusionPhysicians act on drug interaction alerts selectively, and the alert classifications seem to guide how they are used.
