- Limitations and caveats
The corona virus (COVID-19) global pandemic adversely impacted the ICU clinical trial. The pandemic influenced many aspects of patient availability for enrollment, changes to patient management including sedation regimens and clinical practice in the care of critically ill patients receiving mechanical ventilatory support. Fewer than planned patients randomized to dexmedetomidine self-management of sedative therapy actually received the experimental intervention, resulting in unbalanced numbers.

Registered outcomes25
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Anxiety Rating Using the 100mm Vertical Visual Analog Scale | 7 days | Vertical 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. |
| Primary | Duration of Mechanical Ventilatory Support After Study Enrollment | 7 days | Duration of time (hours) patients received mechanical ventilatory support after randomization to either Control or dexmedetomidine self-management of sedative therapy to extubation. |
| Primary | Incidence of Delirium Using the Confusion Assessment Method-ICU (CAM-ICU) | 7 days | Confusion Assessment Method-ICU (CAM-ICU) used to assess for the presence (CAM-ICU+) or absence (CAM-ICU-) of delirium at each assessment. |
| Secondary | Comparison 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. |
| Secondary | Comparison 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. |
| Secondary | Comparison 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). |
| Other | Comparison of Post-ICU Physical Status Using the Katz Activities of Daily Living Scale | Independence 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. |
| Other | Comparison of Post-ICU Psychological Well-being Status Using the Patient Health Questionnaire-9 | 3 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. |
| Other | Comparison of Post-ICU Psychological Well-being Status Using the Posttraumatic Stress Disorder Checklist Event Specific (PCL) Scale | 3 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. |
| Other | Comparison of Post-intensive Care Unit Health-related Quality of Life Using the Short-Form 36 Physical Function Domain | 3 months after ICU discharge over the telephone Physical Function Domain | 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. |
