The purpose of this randomized clinical trial is to test the efficacy of dexmedetomidine for the self-management of sedative therapy (SMST) in a sample of critically ill patients receiving mechanical ventilator support. The investigators hypothesis is that self-management of sedative therapy by mechanically ventilated patients in the intensive care unit (ICU), tailored to their individual needs will be more efficacious than nurse-administered sedative therapy in reducing anxiety, which may reduce duration of mechanical ventilator support and occurrence of delirium.

Primary Outcome Measures:
  • Changes in duration of days receiving mechanical ventilation after study enrollment [ Time Frame: up to 6 months ] [ Designated as safety issue: No ]
    Patients' self-management of sedative therapy (SMST) using dexmedetomidine compared to usual sedation practices in mechanically ventilated subjects.

  • Changes in delirium using the CAM-ICU tool [ Time Frame: 7 days ] [ Designated as safety issue: No ]
    Confusion Assessment Method-ICU (CAM-ICU) will be used as a pre-enrollment delirium screening tool and to measure level of alertness and presence of delirium

  • Changes in anxiety using the 100mm vertical visual analog scale [ Time Frame: 7 days ] [ Designated as safety issue: No ]
    Vertical visual analog scale will be used to measure level of state anxiety

Secondary Outcome Measures:
  • Comparison of level of arousal and alertness using the Richmond Agitation-Sedation Scale [ Time Frame: 7 days ] [ Designated as safety issue: No ]
    The Richmond Agitation-Sedation Scale will be used to measure level of arousal and alertness

  • Comparison of sedative exposure (sedation frequency + sedation intensity) using electronic health record data of intravenous sedative medications. [ Time Frame: each 24-hour period, up to 7 days ] [ Designated as safety issue: No ]
    Frequency of intravenous sedatives medications sums the number of sedative medication doses administered to participant during each 4-hour time period during a 24-hour day. Sedation intensity is a score derived from aggregate dose frequency and dosing of each sedative medications administered to all study participants each 4-hour time period over the 24-hour study day. Scores are summed for the 24-hour period over the 6, 4-hour time blocks to produce a daily sedation intensity score.

Other Outcome Measures:
  • Comparison of post-ICU physical status using the Katz Activities of Daily Living scale [ Time Frame: 3 and 6 months after ICU discharge over the telephone ] [ Designated as safety issue: No ]
    Physical status will be assessed by the Katz Activities of Daily Living scale to assess basic physical abilities like bathing, feeding with 6 questions

  • Comparison of post-ICU functional status using the Functional Activities Questionnaire [ Time Frame: 3 and 6 months after ICU discharge over the telephone ] [ Designated as safety issue: No ]
    Functional status will be assessed by the Functional Activities Questionnaire that contains 10 questions that assess instrumental activities of daily living such as cooking, driving, managing finances.

  • Comparison of post-ICU psychological well-being status using the Patient Health Questionnaire [ Time Frame: 3 and 6 months after ICU discharge over the telephone ] [ Designated as safety issue: No ]
    Psychological well-being will be assessed by the Patient Health Questionnaire is a 9-item tool that tracks symptoms of major depression

  • Comparison of post-ICU psychological well-being status using the Posttraumatic Stress Disorder Checklist Event Specific scale [ Time Frame: 3 and 6 months after ICU discharge over the telephone ] [ Designated as safety issue: No ]
    Psychological well-being will also be assessed with the Posttraumatic Stress Disorder Checklist Event Specific toll to measure symptoms of posttraumatic stress disorder.

  • Comparison of post-intensive care unit health-related quality of life using the Short-Form 36 [ Time Frame: 3 and 6 months after ICU discharge over the telephone ] [ Designated as safety issue: No ]
    Post-intensive care unit health-related quality of life will be assessed by the Short-Form-36

Arms Assigned Interventions
No Intervention: Control
These patient will get usual care - sedation administered by ICU Nurses as deemed necessary by primary care team
Experimental: Intervention

Drug: Dexmedetomidine
Patient will receive a maintenance intravenous infusion of medication (Dexmedetomidine) and have access to self-controlled sedation medication (Dexmedetomidine) for anxiety.

Detailed Description:

The overall objective of this study is to demonstrate efficacy for conducting a future, pragmatic effectiveness trial to test whether self-management of sedative therapy (SMST) is superior to nurse-administered sedative therapy in day-to-day intensive care unit (ICU) practice. This efficacy trial is powered for the investigators primary, clinically relevant endpoints (anxiety, duration of mechanical ventilation, and delirium presence), and examines patient outcomes adversely affected by sedative administration practices, such as prolonged ICU stays, altered mental status, and diminished post-ICU quality of life. This randomized clinical trial with a total of 190 mechanically ventilated patients enrolled and maintained on protocol will address the following Specific Aims.

The primary aim is to determine the efficacy of SMST compared to nurse-administered sedative therapy on anxiety, duration of mechanical ventilation, and presence of delirium in mechanically ventilated patients (MVPs).

The secondary aim is to compare level of arousal and sedative exposure in mechanically ventilated patients (MVPs) randomized to SMST to those MVPs receiving nurse-administered sedative therapy. The investigators hypothesize that SMST patients will be easily arousable, more alert, and exposed to less sedation than those who receive nurse-administered sedative therapy.

An exploratory aim is to compare post-ICU outcomes (physical/functional status, psychological well-being, and health-related quality of life) between MVPs randomized to SMST and those receiving nurse-administered sedative therapy.
