Improved intensive care lighting and staff wellbeing: A pilot feasibility service evaluation.

ABSTRACT:

Background

The lighting environment in intensive care units (ICUs) is markedly different from natural light, potentially disrupting patients' circadian rhythms and impacting staff wellbeing. New lighting technologies may mitigate these effects.

Methods

A mixed methods service evaluation was conducted in a London ICU using Dyson Lightcycle™ luminaires (DLs) to evaluate staff wellbeing. Wellbeing assessments and user perceptions of the built environment were conducted using validated questionnaires before, during, and after DL deployment. Existing ambient light usage was measured using HOBO devices installed on the ceiling. Additionally, data on DL usage (including spectral data) were collected continuously using Raspberry Pi™ sensors.

Results

DL usage was high (>70% pe
