Article Title: Noise exposure among staff in intensive care units and the effects of unit-based noise management: a
monocentric prospective longitudinal study
Author(s): Number:
Christoph Armbruster , Stefan Walzer , Sandra Witek, Sven Ziegler NLM UID: 38057790
and Erik Farin-Glattacker Accession Number: PMC10699060
Population, size, and setting: Publication date:
Population: Staff working in three ICUs (anesthesiological,
neonatological, neurological) at a German university hospital. 2023
Sample Size: 179 participants completed at least one survey (T0
n=115, T1 n=96, T2 n=96).
Setting: University Medical Center Freiburg, Germany.
Complete after appraisal:
Evidence level and quality rating: Level II / Good
Study findings that help answer the EBP question:
Noise exposure: Staff reported high baseline noise-related strain (~3 on a 1–4 scale). No statistically significant reduction
over time following intervention.
Intervention: Three-part strategy are noise traffic lights, guideline implementation, unit-based measures (education,
posters, and technical adjustments).
Other findings:
High awareness of noise issues and belief that behavior change can help reduce noise.
Most perceived noise sources: alarms, ventilators, telephones, colleague conversations.
Minor significant changes in some awareness and thematization items but no sustained noise strain reduction.
