Trial Outcomes & Findings for Post-Operative Delirium in Elderly Surgical Patients (NCT NCT00590707)

NCT ID: NCT00590707

Last Updated: 2018-06-11

Results Overview

The presence of delirium is assessed by the confusion assessment method (CAM), during postoperative Day 1 to Day 5 or up to hospital discharge, whichever occurs first. The CAM consists of 4 features: 1-Onset, 2-Inattention, 3-Disorganized thinking, and 4-altered level of consciousness. The diagnosis of delirium by CAM is based on the presence of features 1 and 2, and either 3 or 4.

Deeper Sedation
Patients randomly assigned to this arm will receive enough sedative drugs to keep their level of awareness during the hip fracture repair, as measured by the use of the Observer's Assessment of Awareness/Sedation Scale (OAA/S), at an OAA/S score of 0. This is the "deeper sedation" arm. Deeper sedation: The depth of sedation, as measured by the use of the Observer's Assessment of Awareness/Sedation Scale (OAA/S), will be maintained at an OAA/S score of 0.
Moderate Sedation
Patients randomly assigned to this arm will receive enough sedative drugs to keep their level of awareness during the hip fracture repair, as measured by the use of the Observer's Assessment of Awareness/Sedation Scale (OAA/S), at an OAA/S score of 4-5. This is the "moderate sedation" arm. Moderate sedation: The depth of sedation, as measured by the use of the Observer's Assessment of Awareness/Sedation Scale (OAA/S), will be maintained at an OAA/S score of 4-5.

SECONDARY outcome

Timeframe: 12 months post-operative

Clinical Dementia Rating consists of 6 domains ("boxes") of function: memory, orientation, judgment and problem solving, community affairs, home and hobbies, and personal care. Each domain ("box") is rated on a 5-point scale (0= no impairment, 0.5=questionable impairment, 1= mild impairment, 2= moderated impairment, 3= severe impairment. The CDR-SOB score is a sum of these ratings, for a total Sum of boxes ranging from 0-18, where 0=cognitively intact. Increasing sum of boxes score is associated with greater cognitive impairment.
