About this trial
Delirium is a frequent and serious problem in hospitalized patients; it is associated with multiple hospital-acquired complications. There is evidence that the incidence of deliri-um may be minimized by multimodal interventions (pain management, shortening the duration of mechanical ventilation, light sedation, avoiding benzodiazepines, routine delirium monitoring, and early mobilization). Even though a clear association between sleep and delirium has not been established, many studies suggest that sleep disturban-ces may be a key risk factor for the development of delirium. Therefore, sleep promoti-on is becoming an integral part of clinical care. The project support the hypothesis that non-pharmacological preventive interventions promoting sleep (sleep protocol) positive-ly influence the quality of sleep and reduce the incidence of delirium in hospitalized patients. This will be verified by qualitative and quantitative research methods, with the quantitative study being divided into three prospective cross-sectional studies and one interventional study. Data will be obtained from 3240 hospitalized patients by combi-ning subjective methods (questionnaire surveys) and objective measurements (acti-graphy). The project outcomes will allow better understanding of the relationship betwe-en sleep and delirium. A set of non-pharmacological preventive interventions promoting sleep will be developed, with a subsidiary aim to potentially reduce the incidence of delirium in hospitalized patients.

Trial outcomes
Primary outcomes
Change quality of sleep during hospitalization (subjectively and objectively)
Assessment of quality of sleep using Richards Campbell Sleep Questionnaire (RCSQ) five-item visual analogue scale was designed as an outcome measure for assessing the perception of sleep in patients. The RCSQ contains 5 items (sleep depth, sleep latency, awakenings, returning to sleep and sleep quality) plus noise as an optional item (evaluated separately). Each item is scored by using a 0-100 visual analogue scale. The total score is calculated as the mean of all items, with 0 and 100 representing the worst and best sleep, respectively. Objectively sleep were assed by actigraphy -the method collects and stores data generated by patient movements.
Secondary outcomes
Change of the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU)
This is a two-step assessment of delirium. The first step is to assess arousal with the Richmond Agitation and Sedation Scale. The second step is assessment of the presence/absence of delirium using four features; delirium is ruled out when none of them is present.
Change of the Confusion Assessment Method (CAM)
The instrument assesses the presence/absence of delirium using four features; delirium is ruled out when none of them is present.
Change of Ford Insomnia Response to Stress Test: FIRST (self-reported)
The instrument comprises 9 items (scenarios) to identify individuals predisposed to situational sleep disturbances. The FIRST consists of 9 items which are scored on a four point-scale. High scores are indicative of greater vulnerability to sleep disruption. Total FIRST scores range from 9 to 36.
Change of Sleep in the Intensive Care Unit Questionnaire (SICQ) (self-reported)
The most widely used instrument for assessing factors causing sleep disturbances in the ICU. The final version contains 27 items divided into 4 dimensions (sleep quality, daytime sleepiness, disruptive factors produce by the healthcare team and environmental disruptive factors). The ratings use a 1-10 Likert scale.
