Flexibility and Innovation in Decisional Capacity Assessment.

Since the 1980s, the four skills criteria have become the most widely accepted mechanism for the assessment of decisional capacity in the United States. These criteria emerged in response to the paternalistic approach to clinical decision-making that had been widely accepted in an earlier era and offered a means of ensuring that physicians honored the rights of capacitated patients to make their own medical decisions. Unfortunately, the criteria are now applied to situations for which they are not suited and in a manner that is often highly inflexible. In an article in this issue of The Journal, Matthew Dernbach and colleagues describe one potential scenario that requires a flexible approach to using the four skills model: situations in which a patient stands at high risk of losing decisional capacity in the near future. Using Dernbach et al. as a starting point, this article offers specific ways in which the four skills model can be improved upon or augmented without abandoning its key principles. These advances include adjusting to empirical evidence, re-emphasizing the importance of autonomy maximization and restorability, and embracing novel conceptual and technological innovations.
