The goal of this multi-site observational study is to compare delirium rates, days on mechanical ventilation, and Post Intensive Care Syndrome (PICS) rates in adult Intensive Care Unit (ICU) patients. The study will examine patients whose sedation and analgesia infusion titration is managed with both Richmond Agitation and Sedation Scale (RASS) and Processed Electroencephalography (pEEG) monitoring vs patients who receive RASS monitoring alone.
The main questions are:
The purpose of this study is to determine the impact of using a 4 channel pEEG monitor to guide sedation and analgesia management in conjunction with RASS in ventilated patients in the ICU on length of time patients experience delirium, number of days patients spend on a ventilator, and incidence of PICS in these same patients.
Participants who are on a mechanical ventilator and on IV sedation or analgesia will be placed on a pEEG monitor on admission to ICU.
Participants will complete a battery of test at discharge, one month post discharge, and three months post discharge to assess for PICS.

| Measure | Description | Time Frame |
|---|---|---|
| Delirium | Measured by Intensive Care Delirium Screening Checklist (ICDSC). The items include the assessment of: (1) consciousness ( deep sedation/coma, agitation, normal wakefulness, or light sedation); (2) inattention; (3) disorientation; (4) hallucination, delusion, or psychosis; (5) psychomotor agitation or retardation; (6) inappropriate speech or mood; (7) sleep-wake cycle disturbances; and (8) fluctuation of symptomatology. The maximum score is eight; scores of ≥4 indicate the presence of delirium and score zero is indicate not in delirium. Each item is scored 0-8. | For the time the patient remains in ICU until discharge from ICU. Average length of stay in ICU is 7 days. |
| Measure | Description | Time Frame |
|---|---|---|
| Days of Mechanical Ventilation | Measured at ICU discharge, measured as half days. | From the date of intubation until extubation in ICU. Average length of mechanical ventilation is 7 days. |
| Sedation Infusions (Propofol and/or Midazolam) |

Rates and dosages of sedation infusions
| Measured every 4 hours while the patient remains on the infusion in ICU. Average length of time spent on a sedation infusion is 5 days. |
| Combined Sedation and Analgesia Infusions (Dexmedetomidine and/or Ketamine) | Rates and dosages of sedation and analgesic infusions | Measured every 4 hours while the patient remains on the infusion in ICU. Average length of time spent on a combined sedation and analgesic infusion is 3 days. |
| Analgesia Infusions (Fentanyl, Morphine, and/or Hydromorphone) | Rates and dosages of analgesic infusions | Measured every 4 hours while the patient remains on the infusion in ICU. Average length of time spent on an analgesic infusion is 5 days. |
| Computerized Neurocognitive Screening Vital Signs | CNS Vital Signs (CNSVS) is a computerized neurocognitive test battery that was developed as a routine clinical screening instrument. It is comprised of seven tests: verbal and visual memory, finger tapping, symbol digit coding, the Stroop Test, a test of shifting attention and the continuous performance test. Standard Scores are normalized from raw scores and present an age matched score relative to other people in a normative sample. CNS Vital Signs standardized have a mean of 100 and a standard deviation is 15. Higher scores are always better. | At hospital discharge (4 days +/- 1) average length of stay in hospital 5-90 days, 1 month post discharge, 3 months post discharge |
| Hospital Anxiety and Depression Scale | The questionnaire comprises seven questions for anxiety and seven questions for depression. For both scales, scores of less than 7 indicate non-cases, score of 8-10 mild case, 11-14 moderate case, and 15-21 severe case. | At hospital discharge (4 days +/- 1) average length of stay in hospital 5-90 days, 1 month post discharge (6 days +/- 1) , 3 months post discharge (6 days +/- 1) |
| Impact of Events Scale-Revised | The IES-R is a validated 22-item self-report scale measuring psychological stress reactions after a major life or traumatic event.1-3Items are rated with reference to the past 7 days on a 5-point scale, ranging from 0 to 4. Three subscale scores are calculated by taking the mean of the item responses: Intrustion (8 items), Avoidance (8 items), and Hyperarousal (6 items). The total score is similarly computed by taking the mean of all 22 items. All scores range from 0 to 4, with higher scores indicating higher event-related distress. Internal consistency estimates(Cronbach's alpha) for all scores range between 0.79 to 0.92. | At hospital discharge (4 days +/- 1) average length of stay in hospital 5-90 days, 1 month post discharge (6 days +/- 1) , 3 months post discharge (6 days +/- 1) |
| EuroQol-5D-5L | Health related quality of life questionnaire EuroQol-5D-5L is used. Five levels are score in 5 dimensions. It is scaled from 0 to 100%. A higher score indicates a higher quality of life. | At hospital discharge (4 days +/- 1) average length of stay in hospital 5-90 days, 1 month post discharge (6 days +/- 1) , 3 months post discharge (6 days +/- 1) |
| Suppression Ratio | Percentage of time the patient's brain is in burst suppression. Scored on a numerical scale 0-100%. A lower percentage is better. | From the time pEEG monitoring is initiated until it is discontinued. Average length of time spent on a pEEG monitor is 5 days. |
