About this study

The investigators plan to create several sleep/circadian rhythm friendly rooms within the medical intensive care unit to determine if decreasing sleep fragmentation effects recovery in patients hospitalized in the ICU.

Read the detailed description

Critically ill patients are known to suffer from severely fragmented sleep with a predominance of stage I sleep and a paucity of slow wave and REM sleep. The causes of this sleep disruption include the intensive care unit (ICU) environment, medical illness, psychological stress, and many of the medications and other treatments used to help those who are critically ill. Surveys have identified poor sleep as one of the most frequent complaints among patients who have survived a critical illness. Patients in medical, cardiac, and surgical ICUs almost uniformly have fragmented sleep.

Although illness, pain, and medications contribute to sleep disruption in ICU patients, the primary factor causing sleep disruption had been thought to be the ICU environment. Noise from various sources, including ventilators, alarms, television, phones, beepers, and conversation, have all been purported to disturb sleep in the ICU. Patients have reported that noise, specifically talking, is a frequent cause of sleep disruption in the ICU. Several studies have confirmed that peak noise levels in ICUs are far in excess of 45 dB during the day and 35 dB at night, which are the recommendations of the Environmental Protection Agency for peak noise levels in the ICU.

The clinical importance of this type of sleep disruption in critically ill patients, however, is not known. The investigators hope to determine if placing patients in sleep/circadian rhythm friendly rooms will enable them to achieve better sleep, suffer from decreased delirium, and have improved recovery from their critical illness.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Sleep/Circadian FriendlyBehavioural

    This intervention attempts to improve sleep and prevent circadian rhythm dysregulation among patients admitted to the medical intensive care unit (MICU). Patients within his arm will be asked to try to keep their TV off and limit their telephone use from 10pm-7am, as well as limit the amount of visitors in their room as much as possible between those hours. Patients will also be offered ear plugs and eye masks if they wish to use at night to aid in helping them sleep, if deemed medically safe to do so. Additionally nurses will be asked to bathe patients either before 10pm or after 7am, to limit their conversations in the patient's room at night, and try as much as possible to limit blood draws and waking patients during those hours as is medically safe. Nurses will also be instructed to lower the blinds in the room at 10 pm and raise them up at 7am to help with patients sleep/wake cycle.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Length of Stay in ICU

    Time spent from admission to ICU until transfer/discharge or study cessation

    Measured: through study completion, an average of 3-4 days

  2. Overall Hospital Length of Stay

    Total time spent from admission to ICU until discharge from hospital

    Measured: at study completion, an average of 5-7 days

  3. Rate of ICU mortality

    rate of mortality while admitted to ICU

    Measured: at study completion, up to 30 days

  4. Rate of Delirium

    Assess development of delirium through administration of CAM-ICU and RASS performed daily by nursing staff per routine care. Delirium will be considered present if CAM-ICU is positive or RASS above +1 or below -1 at anytime during study.

    Measured: Once daily throughout study, on average 3-4 days

  5. Hospital Readmission Rate

    rate of hospital readmission within 30-days of discharge

    Measured: 30 days after discharge

Secondary outcomes (6)
  1. ICU sleep score

    Assess sleep quality through administration of Richard Campbell Sleep Questionnaire (RCSQ). RCSQ is a simple and validated survey to measure sleep quality in ICU settings. RCSQ consists of a series of 8 patient reported questions covering sleep depth, sleep latency, total amount of sleep, number of awakenings, sleep quality, noise rating, light rating, and sleep quality compared to at home. All questions are to be reported on a scale of 0-100 with higher values corresponding to better sleep values.

    Measured: daily through study completion, an average of 3-4 days

  2. Overnight Sound Intensity Levels

    sound intensity (decibel) within patient room with be continuously recorded through SDL-600 industrial decibel monitors.

    Measured: through study completion, an average of 3-4 days

  3. Overnight Light Intensity Exposure

    amount of light patients are exposed to overnight, measured in lux, will be continuously recorded through specialized medical lux monitors.

    Measured: through study completion, an average of 3-4 days

  4. Concentration of Interleukin-6 (IL-6) and interleukin-10 (IL-10)

    concentrations of IL-6 (pg/mL) and IL-10 (pg/mL), inflammatory cytokines found to play a role in circadian regulation, levels will be measured from approximately 2mL of plasma that will be collected concurrently during morning routine care lab draw.

    Measured: Study Day 1 and Day 2

  5. Concentration of 6-sulphatoxymelatonin (aMT6s)

    concentrations of 6-sulphatoxymelatonin (pg/mL), the primary urine metabolite of melatonin and circadian rhythm phase marker, will be measured from left-over voided urine collected from patients prior to discard.

    Measured: Study Day 1 and Day 2

  6. Concentration of Lipopolysaccharide binding protein (LBP)

    Levels of LBP (pg/mL), an acute phase protein that upregulates during an inflammatory physiologic state, will be measured from 2mL of blood taken concurrently with routine morning labs.

    Measured: Study Day 1 and Day 2
