ListOutcomeTime frameDescription
PrimaryAnxiety Rating Using the 100mm Vertical Visual Analog Scale7 daysVertical visual analog scale will be used to measure level of state anxiety from 0/zero (no anxiety) to 100 (most anxiety ever). Higher scores mean more anxiety.
PrimaryDuration of Mechanical Ventilatory Support After Study Enrollment7 daysDuration of time (hours) patients received mechanical ventilatory support after randomization to either Control or dexmedetomidine self-management of sedative therapy to extubation.
PrimaryIncidence of Delirium Using the Confusion Assessment Method-ICU (CAM-ICU)7 daysConfusion Assessment Method-ICU (CAM-ICU) used to assess for the presence (CAM-ICU+) or absence (CAM-ICU-) of delirium at each assessment.
SecondaryComparison of Level of Arousal and Agitation Using the Richmond Agitation-Sedation Scale (RASS)7 days
The Richmond Agitation-Sedation Scale (RASS) was used to assess the level of alertness and agitation in enrolled patients. Scores range from -5 to +4. RASS 0/zero indicates alert and calm patient. Negative scores (-1 to -5) indicate increasing level of sedation with -5 indicating unarousable. Positive scores indicate increasing agitation (+1 to +4) with +4 indicating a combative patient. For enrolled study patients, RASS score -2 (light sedation) to +1 (restless) was considered in range. We report here the total number of patients assessed as outside the desirable range of RASS score -5 to -3 and +2 to +4 by each ICU study day.
SecondaryComparison of Daily Sedation Intensity Each ICU Study Day Using Electronic Health Record Medication Data of Any of Nine Intravenous Sedative Medications Administered to Patients.Daily Sedation intensity over a 7-day ICU study protocol period
Sedation intensity combines the number of sedative doses and the dose amount of any of 9 intravenous (IV) sedative medications (lorazepam, midazolam, propofol, morphine, hydromorphone, dexmedetomidine, fentanyl, haloperidol, ketamine) recorded in the electronic health record, summarized over all patients and time periods each day to obtain medians and quartiles. Each of the 9 sedative drugs administered during each 4-hr period is then assigned a ranking: 0 for drug not used, 1 for the bottom quartile, 2 for the second quartile, 3 for the third, and 4 for the fourth. A score is determined by summing for the 24-hr day over the 6, 4-hour blocks to produce a daily Sedation Intensity Score from 0-36, higher score more intense dosing received of sedative medications.
SecondaryComparison of Daily Sedation Frequency Using Electronic Health Record Medication Data of Any of Nine Intravenous Sedative Medications Administered to Patients.Daily Sedation Frequency over a 7-day ICU study protocol period
Sedation Frequency is the number of individual intravenous (IV) sedative medication(s) doses administered to patients over each 24-hour day of lorazepam, midazolam, propofol, morphine, hydromorphone, dexmedetomidine, fentanyl, haloperidol, ketamine. Sedation frequency ranges from 0-216 with a higher number indicating more frequent receipt of a sedative medication(s).
OtherComparison of Post-ICU Physical Status Using the Katz Activities of Daily Living ScaleIndependence in activities of daily living at 3 months and 6 months after hospital discharge over the telephone
Physical status will be assessed by the Katz Activities of Daily Living scale to assess basic physical abilities like bathing, feeding with 6 questions. Higher scores of 6 indicates the individual is independent, whereas a score of 0 indicates the individual is very dependent.
OtherComparison of Post-ICU Psychological Well-being Status Using the Patient Health Questionnaire-93 and 6 months after ICU discharge over the telephone
Psychological well-being will be assessed by the Patient Health Questionnaire (PHQ-9) is a 9-item tool that tracks symptoms of major depression. Scores range from 9-36, with higher scores indicating altered psychological well-being.
OtherComparison of Post-ICU Psychological Well-being Status Using the Posttraumatic Stress Disorder Checklist Event Specific (PCL) Scale3 months and 6 months after ICU discharge over the telephone
Psychological well-being will be assessed with the Posttraumatic Stress Disorder Checklist Event Specific (PCL) to measure symptoms of posttraumatic stress disorder after a stressful life experience of ICU admission. Scores range from 17-85 with higher scores indicating being symptomatic for posttraumatic stress.

Post-intensive care unit health-related quality of life will be assessed by the Short-Form-36 (SF-36) at 3- and 6-months after hospital discharge. The SF-36 tracks how well an individual feels and how well they are able to do their usual activities in eight health domains: physical functioning, role limitations due to physical health, role limitations due to emotional problems, energy/fatigue, emotional well-being, social functioning, pain, and general health. A higher score defines a more favorable health state scored on a 0-100 range for each of the 8 domain scales.
