Increasing the reporting of adverse drug reaction-related hospitalizations using an ICD-10-based identification workflow: A multicentre study from Switzerland.
Observational study in British journal of clinical pharmacology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundReporting adverse drug reactions (ADRs) is essential for drug safety. In Switzerland, healthcare professionals are legally required to report serious and unlabelled ADRs, yet under-reporting remains widespread. We tested a novel method to increase reporting of ADR-related hospitalizations.
methodsThis retrospective observational study used ADR-indicative ICD-10 codes to screen admissions to four Swiss hospitals, identify suspected drugs and send individual case safety reports (ICSRs) of confirmed cases to Swissmedic.
resultsParticipating hospitals previously reported ~18 ICSRs annually. During the study period (7/2023-12/2023), 200 ADR-related hospitalizations were reported following a review of 814 pre-filtered admissions. Most ICSR data were available in structured format: Median age of patients was 59 (interquartile range [IQR] 42-75); 87 (44%) males; median of two comorbidities (IQR 1-3); the three most frequent ADRs were 'K52.1 Toxic gastroenteritis and colitis' (11 [6%]), 'T42.4 Poisoning by benzodiazepines' (10 [5%]) and 'R11 Nausea and vomiting' (10 [5%]). Discharge reports contained free-text information on suspected drugs: More than half of ADR-related hospitalizations were caused by antineoplastics (45 [23%]), psycholeptics (38 [19%]), opioids and other analgesics (34 [17%]). The median time to screen a case was 1 min, 8 min to collect, compile and send data of confirmed cases.
conclusionThe approach successfully increased reporting of serious ADRs. The time investment for creating ICSRs might soon be rendered obsolete, as most data are available in structured format, and large language models are key to identifying suspected drugs in discharge reports.
