Video-supported telephone triage in emergency primary healthcare: an observational study from Norway.
Observational study in BMJ open, 2026. 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
objectivesTo describe how video support is used in telephone triage at Norwegian Local Emergency Medical Communication Centres (LEMCs), including frequency, call duration, patterns of video use and associations with urgency and response assessments.
designAn observational study using national-level operational data and prospectively collected triage data from the Watchtower Project.
settingNorwegian LEMCs, which provide 24/7 nurse-managed telephone triage within the municipal emergency primary healthcare system, handling a broad range of medical inquiries.
participants79 LEMCs using the Norwegian Air Ambulance video solution in 2024 and six LEMCs participating in the Watchtower Project in 2022-2023.
main outcome measuresFrequency of video use and call duration with and without video support. Video use across caller and patient characteristics and reasons for contact. Changes in urgency level and intended response following video use.
resultsThe national-level dataset included 2 242 522 calls and the Watchtower dataset included 109 281 calls. Nationally, video was used in 4.9% of answered calls. Median call duration was 7:13 min (IQR: 5:09-10:02) with video and 3:58 min (IQR: 2:18-6:16) without video (p<0.001). Video was most frequently used in the evening, for children (47% aged 0-15 years), and in calls initiated by next of kin (58%). Skin-related issues accounted for 65% of all video-supported calls. Following video use, urgency changed in 36% of contacts (22% downgraded, 14% upgraded), and the intended response changed in 31%. Changes occurred in both directions, including shifts between nurse-managed and physician-managed responses.
conclusionVideo-supported calls were longer than non-video calls. Video is used selectively and is associated with bidirectional adjustments in urgency and response assessments in a substantial share of calls.
