Using a novel smartphone app to track noise and vibration exposure during neonatal ambulance transport.
Observational study in Archives of disease in childhood. Fetal and neonatal edition, 2025. 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
objectiveTo assess the utility of a bespoke smartphone app to map noise and vibration exposure across neonatal road ambulance journeys. DESIGN AND
settingProspective observational study of ambulance journeys across a large UK neonatal transport service. Smartphones, with an in-house developed app, were secured to incubator trolleys to collect vibration and noise data for comparison with international standards. A case study exploring alternative routes between hospitals was undertaken.
resultsOver a 12-month period, the app was used to collect data from 1487 interhospital journeys totalling 81 925 km. Noise positively correlated with increasing vehicle speed. Noise exposure never fell below the recommended 45 dB(A) threshold for neonatal patients and exceeded 70 dB(A) for more than 60% of the time. During patient transfers, vibration would be classed as uncomfortable for healthy adults for 68% of journeys. Comparison of 111 journeys on two different routes between the same hospitals demonstrated significantly lower vibration exposure depending on the road type. Safe levels of adult vibration exposure were exceeded on 19% of non-motorway and 3% of motorway journeys between the two hospitals. Vibration and noise levels were significantly higher on concrete compared with asphalt road surface.
conclusionsIt is feasible for neonatal teams to collect detailed route, vibration and noise exposure data using a calibrated smartphone and bespoke app. Collecting large amounts of data and providing live measures to teams could help quantify excessive exposures and guide reduction strategies of these environmental stressors for the benefit of babies, staff and equipment.
