Purpose
To determine whether an advance care planning (ACP) decision aid for could improve communication about end-of-life treatment wishes between patients with amyotrophic lateral sclerosis (ALS) and their clinicians.
Methods
Fourty-four patients with ALS (≥21, English-speaking, without dementia) engaged in ACP using an interactive computer-based decision aid. Before participants completed the intervention, and again 3 months after, their clinicians reviewed 3 clinical vignettes, and made treatment decisions (n=18) for patients. After patients indicated their agreement with the team’s decisions, concordance was calculated.
Results
The mean concordance between patient wishes and the clinical team decisions was significantly higher post-intervention (post=91.9%, 95% CI=87.8, 96.1, vs. pre=52.4%, 95% CI=41.9, 62.9; p <.001). Clinical team members reported greater confidence that their decisions accurately represented each patient’s wishes post-intervention (mean=6.5) compared to pre-intervention (mean=3.3, 1=low, 10=high, p<.001). Patients reported high satisfaction (mean=26.4, SD=3.2; 6=low, 30=high) and low decisional conflict (mean=28.8, SD=8.2; 20=low, 80=high) with decisions about end-of-life care, and high satisfaction with the decision aid (mean=52.7, SD=5.7, 20=low, 60=high,). Patient knowledge regarding ACP increased post-intervention (pre=47.8% correct responses vs. post=66.3%; p <.001) without adversely effecting patient anxiety or self-determination.
Conclusion
A computer-based ACP decision aid can significantly improve clinicians’ understanding of ALS patients’ wishes regarding end-of-life medical care.
