  Title Light and noise nuisance … deciphered yet underappreciated ‘Rosetta Stone’ of the modern ICU? Type Journal Article
  Year 2019 Publication Netherlands Journal of Critical Care Abbreviated Journal

  Abstract In everyday life, we take for granted that public authorities protect us from an unhealthy environment, including light and noise pollution. In recent years, about 1200 kilometres of noise barriers have been built alongside Dutch highways with costs approaching a billion euros. Also, more than 50 cities in the Netherlands have successfully taken initiatives to reduce the artificial light pollution in the past six years, as our country is well known to rank among the literally most illuminated ones in the world. These investments seem to be reasonable as adverse health effects from environmental light and noise pollution have long and widely been recognised. How these potentially detrimental effects of artificial light and distressing noise acting on the human body translate into the best possible care that we strive to provide within our modern ICU environment is an area of increasing professional awareness, interest and research. Yet, we all realise that not only light and noise, but numerous physical and psychological stressors may negatively affect individual ICU patients. Also, the impact of these factors may vary considerably among individuals, which makes it even more difficult for caregivers to prioritise among apparently competing aspects of care in their daily practice. A comprehensive, narrative review by Koen Simons and colleagues in this issue of the Netherlands Journal of Critical Care provides us with up-to-date information on the ‘impact of intensive care unit light and noise exposure on critically ill patients’.Here, we gain more insights and learn how a multimodal approach to our ICU environment may aid to optimise light exposure and reduce noise. This may not only improve our patients’ sleep and general wellbeing, but also

reduce the incidence of delirium. The latter seems especially relevant since the pharmacological prevention of delirium has repeatedly been shown to be disappointing, as recently confirmed again in a large Dutch trial. All this evidence sets the stage to further promote nonpharmacological interventions in the ICU to prevent delirium. Therefore, we should do our best to limit controllable stressors in the ICU in order to improve patient comfort and hopefully enhance the individual prognosis. As our traditional focus on the medical and technical aspects of critical care has led us to asymptotically reach current therapeutic optima; human factors and soft skills are no longer far in the horizon of the modern ICU.

  Title Monitoring sound and light continuously in an intensive care unit patient room: A pilot study Type Journal Article
  Year 2016 Publication Journal of Critical Care Abbreviated Journal Journal of Critical Care  
  Volume 38 Issue 21 Pages 5952-5961  
  Keywords Instrumentation; Human Health  
  Abstract Purpose

To determine the feasibility of continuous recording of sound and light in the intensive care unit (ICU).

Materials and Methods

Four one-hour baseline scenarios in an empty ICU patient room by day and night (doors open or closed and maximal or minimal lighting) and two daytime scenarios simulating a stable and unstable patient (quiet or loud devices and staff) were conducted. Sound and light levels were continuously recorded using a commercially available multisensor monitor and transmitted via the hospital's network to a cloud-based data storage and management system.

Results

The empty ICU room was loud with similar mean sound levels for the day and night simulations of 45–46 dBA. Mean levels for maximal lighting during day and night ranged from 1306–1812 lux and mean levels for minimum lighting were 1–3 lux. The mean sound levels for the stable and unstable patient simulations were 61 and 81 dBA, respectively. The mean light levels were 349 lux for the stable patient and 1947 lux for the unstable patient.

Conclusions

Combined sound and light can be continuously and easily monitored in the ICU setting. Incorporating sound and light monitors in ICU rooms may promote an enhanced patient and staff centered healing environment.
