Instruments for Delirium Assessment Regarding to Analgesia Sedation and Ventilator Status (IDEAS)

This study has been completed.

Claudia Spies, Charite University, Berlin, Germany
ClinicalTrials.gov Identifier:
NCT01720914
First received: October 30, 2012
Last updated: December 22, 2015
Last verified: December 2015
  Purpose

In this prospective, multicenter observational study we assess the diagnostic validity of the following standard screening instruments for delirium regarding sedation, analgesia and ventilator status in critically ill patients:

  • Confusion Assessment Method for the ICU (CAM-ICU)
  • Intensive Care Delirium Screening Checklist (ICDSC)
  • Nursing-Delirium-Screening-Scale (Nu-DESC)

The definite delirium diagnosis (definite in terms of reference standard) is made according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders 4th Edition, text revised (DSM-IV-TR) published by the American Psychiatric Association (APA) which is the Gold Standard to diagnose delirium.

Primary research question: Does sedation, ventilator status and analgesia influence the sensitivity of delirium screening tools (DST)?

Further study details as provided by Charite University, Berlin, Germany:

Primary Outcome Measures:
  • Sensitivity of the delirium screening/diagnosing tool "Confusion Assessment Method for the ICU (CAM-ICU)" regarding sedation and ventilator status. [ Time Frame: Participants will be followed in the 7-days sample period ]
    Used reference standard: DSM-IV TR criteria

  • Sensitivity of the delirium-screening tool "Intensive-Care Delirium Screening Checklist(ICDSC)" regarding sedation and ventilator status. [ Time Frame: Participants will be followed in the 7-days sample period ]
    Used reference standard: DSM-IV TR criteria.

  • Sensitivity of the delirium screening tool "Nursing Delirium Screening Scale (Nu-DESC)" regarding sedation and ventilator status. [ Time Frame: Participants will be followed in the 7-days sample period ]
    Used reference standard: DSM-IV TR criteria


Secondary Outcome Measures:
  • Specificity of the "Confusion Assessment Method for the ICU (CAM-ICU)", the "Intensive Care Delirium Screening Checklist (ICDSC)" and the "Nursing Delirium Screening Scale" regarding sedation and ventilator status. [ Time Frame: Participants will be followed in the 7-days sample period ]
    Used reference standard: DSM-IV-TR criteria.

  • Calculation and Analysis of the positive predictive values of the assessed delirium-screening scales. [ Time Frame: Participants will be followed in the 7-days sample period ]

    Calculation of positive and negative predictive values of the "Confusion Assessment Method for the ICU (CAM-ICU)", the "Intensive Care Delirium Screening Checklist (ICDSC)" and the "Nursing Delirium Screening Scale" regarding sedation and ventilator status.

    Used reference standard: DSM-IV-TR criteria


  • Incidence of delirium [ Time Frame: Participants will be followed in the 7-days sample period ]
    According to Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) and Confusion Assessment Method for the ICU (CAM-ICU)

  • Incidence of Subsyndromale Delirium (SSD) [ Time Frame: Participants will be followed in the 7-days sample period ]
    According to Intensive Care Delirium Screening Checklist (ICDSC) and Nursing Delirium Screening Scale (Nu-DESC)

  • Analgesia [ Time Frame: Participants will be followed in the 7-days sample period: ]
    According to Numeric rating scale visually enlarged and laminated (NRS-V), Behavioural pain scale (BPS) and Behavioural pain scale not intubated (BPS-NI)

  • Ventilator status [ Time Frame: Participants will be followed in the 7-days sample period ]
    Clinical observation of A) whether an airway is used B)whether a patient is ventilated with a positive pressure ventilation or a high flow ventilation for more than 6 hours per day.

  • Administered neuroleptics, cumulative [ Time Frame: Participants will be followed in the 7-days sample period ]
  • Administered analgesics, cumulative [ Time Frame: Participants will be followed in the 7-days sample period ]
  • Administered sedatives, cumulative [ Time Frame: Participants will be followed in the 7-days sample period ]
  • Severity of illness [ Time Frame: Participants will be followed in the 7-days sample period ]
    according to Acute Physiology And Chronic Health score (APACHE 2), Simplified Acute Physiology Score (SAPS 2) and Sequential Organ Failure Assessment score (SOFA)

  • Antibiotics/infections [ Time Frame: Participants will be followed in the 7-days sample period ]
  • ICU length of stay [ Time Frame: Participants will be followed for the duration of intensive care unit stay and hospital stay, an expected average of 4 weeks ]
  • Duration of mechanical ventilation [ Time Frame: Participants will be followed for the duration of intensive care unit stay and hospital stay, an expected average of 4 weeks ]
  • Discharge mode [ Time Frame: Participants will be followed for the duration of intensive care unit stay and hospital stay, an expected average of 4 weeks ]
  • 28-day mortality [ Time Frame: Participants will be followed for the duration of intensive care unit stay and hospital stay, an expected average of 4 weeks ]
  • Specificity of the "Confusion Assessment Method for the ICU (CAM-ICU)", the "Intensive Care Delirium Screening Checklist (ICDSC)" and the "Nursing Delirium Screening Scale" regarding analgesia. [ Time Frame: Participants will be followed in the 7-days sample period ]
    Used reference standard: DSM-IV-TR criteria.

  • Sensitivity of the "Confusion Assessment Method for the ICU (CAM-ICU)", the "Intensive Care Delirium Screening Checklist (ICDSC)" and the "Nursing Delirium Screening Scale" regarding analgesia. [ Time Frame: Participants will be followed in the 7-days sample period ]
