“…Since it is the large unit, it has a considerably larger multidisciplinary staff, more traffic from ancillary support and visitors, and more equipment in use, which contribute to the overall noise levels than do smaller units. Other studies comparing single-room NICU with open-unit NICU (similar to NICU A, B and C) revealed higher noise levels mostly in open-units [26,27]. Basner et al [5] stated that noise levels in hospitals are now typically more than L Aeq 15-20 dB higher than those recommended which is in agreement with the majority of the obtained results ( Table 2).…”

“…In fact, several studies showed that -private room‖ or single-room NICU environment has been the most effective way to address sound issues, especially when used in conjunction with a cultural change among the staff [26,27]. Lastly, regardless of the adjustment period of the operational management in NICU to deal with the new design [35], these singleroom NICU also seems to improve staff satisfaction regarding physical environment and working conditions [36].…”

In NICU, systematic exposure to sound pressure levels above the recommended can affect both ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2 neonates and staff. This study aimed to evaluate the sound pressure levels in three Portuguese NICU and the noise perception of staff. The measurements were performed with a sound level meter, considering the location of the main sources of noise and the layout of the units. A questionnaire was applied to assess noise perception of professionals. The staff classified the environment (regarding noise) as -slightly uncomfortable‖ (41.1%) and 48.4% considered it as -acceptable‖. In addition, the majority (55.5%) considered -equipment‖ as the most annoying source of noise. The results showed that noise levels were excessive in all the evaluated areas of the NICUs, exceeding international guidelines, with the levels ranging between 48.7 dBA to 71.7 dBA. Overall, there is a need for more research in order to verify the effectiveness of some actions and strategies to reduce the impact of noise in NICU.

Objective To quantify early auditory exposures in the neonatal intensive care unit (NICU) and evaluate how these are related to medical and environmental factors. We hypothesized that there would be less auditory exposure in the NICU private room, compared with the open ward. Study design Preterm infants born at ≤ 28 weeks gestation (33 in the open ward, 25 in private rooms) had auditory exposure quantified at birth, 30 and 34 weeks postmenstrual age (PMA), and term equivalent age using the Language Environmental Acquisition device. Results Meaningful language (P < .0001), the number of adult words (P < .0001), and electronic noise (P < .0001) increased across PMA. Silence increased (P = .0007) and noise decreased (P < .0001) across PMA. There was more silence in the private room (P = .02) than the open ward, with an average of 1.9 hours more silence in a 16-hour period. There was an interaction between PMA and room type for distant words (P = .01) and average decibels (P = .04), indicating that changes in auditory exposure across PMA were different for infants in private rooms compared with infants in the open ward. Medical interventions were related to more noise in the environment, although parent presence (P = .009) and engagement (P = .002) were related to greater language exposure. Average sound levels in the NICU were 58.9 ± 3.6 decibels, with an average peak level of 86.9 ± 1.4 decibels. Conclusions Understanding the NICU auditory environment paves the way for interventions that reduce high levels of adverse sound and enhancing positive forms of auditory exposure, such as language.

“…Higher physical demands and workloads placed on nurses could negatively affect the level of care provided. Additional key physical characteristics include internal and external noise [50,51], temperature control, exposure to light [52,53], practice of developmentally supportive care [54], provision and extent of family-centered care, provision and extent of breastfeeding support, potential for continuous parental involvement, as well as training and preparation for discharge home.…”

The International Network for Evaluating Outcomes of very low birth weight, very preterm neonates (iNeo): a protocol for collaborative comparisons of international health services for quality improvement in neonatal care

BackgroundThe International Network for Evaluating Outcomes in Neonates (iNeo) is a collaboration of population-based national neonatal networks including Australia and New Zealand, Canada, Israel, Japan, Spain, Sweden, Switzerland, and the UK. The aim of iNeo is to provide a platform for comparative evaluation of outcomes of very preterm and very low birth weight neonates at the national, site, and individual level to generate evidence for improvement of outcomes in these infants.Methods/designIndividual-level data from each iNeo network will be used for comparative analysis of neonatal outcomes between networks. Variations in outcomes will be identified and disseminated to generate hypotheses regarding factors impacting outcome variation. Detailed information on physical and environmental factors, human and resource factors, and processes of care will be collected from network sites, and tested for association with neonatal outcomes. Subsequently, changes in identified practices that may influence the variations in outcomes will be implemented and evaluated using quality improvement methods.DiscussionThe evidence obtained using the iNeo platform will enable clinical teams from member networks to identify, implement, and evaluate practice and service provision changes aimed at improving the care and outcomes of very low birth weight and very preterm infants within their respective countries. The knowledge generated will be available worldwide with a likely global impact.
