Assessing the Incidence of Postoperative Delirium Following Aortic Valve Replacement (IPOD-AV)

Study Description
Brief Summary:
Our primary aim in this observational study is to identify the incidence of POD in the first five postoperative days by using the 3-minute Diagnostic confusion assessment method (3D-CAM), the derived version for intensive care unit (CAM-ICU) or nurse reports in patients undergoing different techniques of aortic valve replacement. Patients are followed 5 days postoperative with the 3D-CAM or until resolution of POD. Six months postoperatively, a follow-up by phone is planned for activity of daily living (ADL).

Condition or disease
Postoperative Delirium Aortic Valve Stenosis

Detailed Description:
A significant and often underrecognized complication after surgery is postoperative delirium (POD) causing increased morbidity and mortality. This is especially true for the older cardiac surgical patient, in whom the incidence of POD is up to 70%. Surgical invasiveness and herewith related inflammation, a cholinergic load of medications, postoperative pain or use of opioids are examples of precipitating factors that can be altered to reduce the incidence of POD. Transaortic valve replacement (TAVR) is a revolutionary technique that has led to a dramatic decrease in surgical invasiveness and improved outcomes in high-risk surgical patients. However, only a few studies evaluated neurocognitive outcome after surgical aortic valve replacement (SAVR) compared to TAVR, suggesting a reduced incidence of POD with TAVR compared to SAVR. In contrast, other studies found almost no difference in POD in the aforementioned patient groups. Hence, it remains still unclear which technique best to use in patients at high risk for POD.

Arms and Interventions
Outcome Measures
Primary Outcome Measures :
  1. Incidence of postoperative delirium [ Time Frame: During the first five postoperative days or until discharge, in case of POD followup until resolution of POD or discharge. ]
    Using the 3-minute Diagnostic confusion assessment method (3D-CAM), the derived version for intensive care unit (CAM-ICU) or nurse reports combined with interview with the caregivers and patient


Secondary Outcome Measures :
  1. Onset postoperative delirium [ Time Frame: During the first five postoperative days or discharge ]
    Moment of onset of POD

  2. Duration of POD [ Time Frame: If POD develops during the first 5 postoperative days, patient will be followed until POD has resolved or until discharge ]
    Duration of delirium in days using the 3D-CAM or ICU-CAM

  3. Severity of POD [ Time Frame: If POD develops during the first 5 postoperative days, patient will be followed until POD has resolved or until discharge ]
    assessed with the delirium severity measure-based CAM (CAM-S Long)

  4. Early safety according to VARC-2 [ Time Frame: 30 days ]
    Early safety (at 30 days) defined by the Valve Academic Research Consortium (VARC)-2

  5. Clinical efficacy according to VARC-2 [ Time Frame: 6 months ]
    Clinical efficacy (at 6 months) as defined by VARC-2


Other Outcome Measures:
  1. Intensive care unit (ICU) length of stay [ Time Frame: 30 days ]
    Intensive care unit (ICU) length of stay

  2. Hospital length of stay [ Time Frame: 30 days ]
    Amount of days hospitalized in the primary center

  3. Discharge destination [ Time Frame: 30 days ]
    Discharge destination defined as: home, nursing home, revalidation unit or other hospital.

  4. 6-months interview [ Time Frame: 6 months ]
    Assessment of different questionnaires: self-administered instrumental activities of daily living, 5 dimensional quality of life (EQ-5D-5L), visual analoge scale for quality of life (EQ-VAS) and cognitive failure questionnaire.
