Establishing a Contextualized Intervention Program for Noise Reduction in a Neonatal Intensive Care Unit

Abstract

Objective: This study aimed to examine the effect of a contextualized intervention program on the level of noises in the neonatal intensive care unit (NICU) in Konya, Turkey. Background: For the healthy development of preterm infants, NICUs should have noise levels within safe limits. Methods: A single-center, before-and-after study design was employed. Participants included one head nurse, four physicians, 42 nurses, six physician assistants, and 14 other staff members. The contextualized intervention program involved environmental modification, behavioral modification, and resource management. Sound level measurements were recorded at two-hour intervals over a week before the program's initiation, after the first cycle, and following the installation of central monitor screens. Data analysis utilized SPSS 25, employing percentile calculations, one-way analysis of variance, and Bonferroni tests. Results: The evaluations in the second level of NICU showed that the noise level recorded on weekday mornings and evenings was significantly lower for the third measurement compared to the first and second measurements. However, at the weekend the noise level recorded in the morning was higher in the second measurement than the first, with no significant difference found for the third measurement. The evaluations in the third level of NICU showed that on weekdays the noise level recorded in the third measurement was significantly lower than in the first and second measurements (p < .05). Conclusion: The implementation of a contextualized noise reduction program in our NICU led to significant improvements in noise levels, particularly during morning and evening shifts.
