Objectives:
Treatment decisions for severe aortic stenosis (AS) are complex, since there are two active and comparable options: transcatheter aortic valve implantation and surgical aortic valve replacement. The disease predominantly affects older individuals, who are frequently comorbid with from cognitive impairment. This study aimed to establish a screening-triggered system to assess the decision-making capacity of patients with AS, support their decision-making, and facilitate referrals to specialists when necessary.
Methods:
This is a retrospective pre-post observational study. Relevant healthcare professionals were trained to assess and support patients' decision-making capacities.
Results:
Subtotals of 203 and 244 patients were enrolled before and after the implementation of the system, respectively. The requests for decision-making support significantly increased (from 1.5 % to 14.8 % of the patients). 11.5 % of the patients were identified as with declined decision-making capacity. The proportion of patients who received active treatments for AS significantly decreased from 95.0 % to 83.0 %. The nurses' documentation of patients' decision-making capacities significantly increased.
Conclusion:
This screening-triggered system identified a substantial proportion of patients with declined decision-making capacity. A significant decrease in patients receiving active treatments for AS and increased documentation of patients' decision-making capacities in nursing records were observed. A future randomized controlled is warranted.
