Human Centric Lighting to Improve Patient Sleep Parameters
- Conditions
- Sleep Disturbance
- Interventions
- Device: Human Centric Lights
- Registration Number
- NCT05039749
- Lead Sponsor
- Landstuhl Regional Medical Center
- Brief Summary
Human centric lighting (HCL) is a technology that supports the body's circadian rhythm, as it can stimulate the sleep triggering hormone, melatonin, to improve sleep hygiene over standard lighting (SL), and promote recuperative sleep for a timely return-to-duty. In intensive care units, exposure to HCL has improved sleep measures. However, the effect in the medical surgical (MS) environment is unknown. The purpose of this study is to assess the feasibility of study procedures in MS setting and conduct a preliminary evaluation of the effect of light on inpatient sleep. Recruitment started November 2020 through April 2021. Data analysis is pending.

- Patient who is an active duty service member, GS Civilian, Dependent or Retiree affiliated with the Army, Air Force or Navy.
- Patient who is informed by provider or anticipates being admitted for at least two nights.
- Patient who can read and speak English fluently (since surveys are not translated in any other language).

- Patient taking an oral medication for sleep.
- Patient receiving radioactive ionization treatment.
- Patient who requires isolation or palliative care.
- Patient recovering from head/neck or oral maxillofacial surgery that would impede saliva sample collection (i.e. jaw wiring, extensive gauze packing in oral cavity)
- Patient who reports status as a Department of Defense Contractor at screening.

Group Intervention Description Human Central Lighting (HCL) Room Human Centric Lights This inpatient room was outfitted with lights that mimic the day/night cycle, thereby supporting circadian rhythm. Day time lights were automatically on during 0600 to 1900 and in use any time the patients would normally utilize their lights, with a goal of three hours of light exposure per day. The lights automatically transitioned to warmer toned evening lighting at 1900.
- Primary Outcome Measures
Name Time Method Total Sleep Time During participant's inpatient stay, not to exceed 5 days. Assess the feasibility of measuring total sleep time in MS setting, using an actigraphy device.
Dim Light Melatonin Onset - collection During participant's inpatient stay, not to exceed 5 days. Assess the feasibility of collecting samples to assess dim light melatonin onset in MS setting, using passive drool saliva sampling.
Sleep Patterns During participant's inpatient stay, not to exceed 5 days. Assess the feasibility of assessing sleep patterns in MS setting, using a Consensus Sleep Diary (CSD).
Patient experience One time - approximately a 5 to 15 minute interview Describe the patient's experience of participating in the study, in a MS setting, using a semi-structured interview (SSI).
Sleep Efficiency During participant's inpatient stay, not to exceed 5 days. Assess the feasibility of measuring sleep efficiency in MS setting, using an actigraphy device.
- Secondary Outcome Measures
Name Time Method Dim Light Melatonin Onset - analysis Collected during participant's inpatient stay, not to exceed 5 days. Conduct a preliminary evaluation of the effect of light on inpatient sleep using dim light melatonin onset saliva sampling.
