- Registration Number
- NCT03913299
- Lead Sponsor
- Cliniques universitaires Saint-Luc- Université Catholique de Louvain
- Brief Summary
The aim of the study is to assess frailty of patients admited for cardio-vascular surgery in Cliniques Universitaires Saint Luc in Brussels. And analyse the correlation between frailty, functionnal decline and postoperative mortality.
- Detailed Description
Frailty is a state of loss of functional reserve resulting in an increased vulnerability to a stressor event. From a pathophysiological point of view, it is an accelerated decrease in physiological reserve related to ageing.
Currently, evaluation of the outcome after cardiac surgery is commonly based on scores not taking into account the concept of frailty (Society of Thoracic Surgeons (STS) and Eurosore II) Recent studies have shown an independent association between post cardiac surgery mortality and pre-operative frailty. Beyond cardiac surgery, frailty has been shown to be associated with higher mortality and morbidity among intensive care unit (ICU) patients. Frailty is commonly assessed for patients older than 75 years of age but the prevalence in younger patients admitted to the hospital is significant. There is therefore need to evaluate all patients for frailty in the preoperative period.
Since the Edmonton Frail Scale (EFS) allows easy screening of all frailty domains, we hypothesized that it could be a reliable and feasible score to assess preoperative frailty and to predict postoperative morbidity and mortality.
Objectives:
The primary objective of this study is to evaluate preoperative frailty in all adult patients undergoing cardiac and vascular surgery.
The secondary objectives are:
* to evaluate the association between frailty and postoperative mortality.
* to evaluate the association between frailty and postoperative functional decline (nursing home admission or care dependency)
* to evaluate impact of each frailty domain on the post-operative outcomes (mortality and functional decline)
* to evaluate how to integrate frailty with the others preoperative clinical parameters to better predict postoperative outcome
Measurement:
Assessment of frailty will be performed using EFS. Other clinical conditions related to frailty will be collected: Body Mass Idex (BMI), tobacco use, alcohol consumption, preoperative albumin and pre-albumin level. STS and Eurosore II will be systematically calculated.
A one-year follow-up will assess the following parameters:
* all-cause mortality
* functional decline with admission to a nursing home or care dependency. Care dependency will be defined by a Katz index more than 0 \[19\].
Follow-up will be realized by a phone call to the patient, his relatives or his general practitioner.
Based on a prevalence of frailty of 11%, we have determined that the enrollment of a minimum of 2080 patients would provide a power of 80% at a significance level of 5% to detect a difference of 5% mortality at one year between frail and non-frail patients.
