Does noise on my neonatal unit matter? Exploratory cross-sectional multiple cohort professional opinion survey study.
Article in BMJ paediatrics open, 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
objectivesTo examine how neonatal staff perceive the clinical impact of noise, including its influence on their performance and its potential contribution to neonatal morbidity.
designA 56-item survey was developed, piloted and disseminated across all nine neonatal units in Wales, UK. Distribution was supported by unit-based study champions and weekly response monitoring. Responses were analysed using descriptive and inferential statistics, as well as inductive thematic analysis.
participantsA total of 405 valid responses were received from clinical staff, including 260 nurses, 126 doctors and 19 allied health professionals, representing 49.6% of all neonatal nurses and doctors in Wales. Respondents spanned all levels of seniority and unit types.
main outcome measuresPrimary outcomes were the proportion of staff who perceived noise as having (1) a direct negative impact on neonatal health and (2) an indirect impact via impaired staff performance. Secondary outcomes included specific perceived clinical consequences (e.g., sepsis, intraventricular haemorrhage, necrotising enterocolitis) and the prevalence of noise-mitigation strategies in practice.
results92% of staff reported that noise directly affects neonatal health; 76% believed that it indirectly contributes to harm through its impact on staff functioning. Nearly half of doctors and over one-third of nurses linked this to serious complications. Free-text responses revealed themes of concern over clinical harm, impaired communication and lack of effective institutional response.
conclusionsNeonatal professionals view noise as a clinically significant risk factor. These findings support the need for system-level noise-reduction strategies and further evaluation through multicentre interventional studies aimed at reducing neonatal morbidity.
