Safeguarding vulnerable adults calls explicitly for the allowance of as much autonomy and control of their lives as possible.
If a vulnerable adult is thought to be unable to make their own decisions or choice, a proper process needs to be followed to determine their decision-making ability. Only after they are declared unfit to make any decisions can important decisions be made for them.
The most important aspect of safeguarding vulnerable adults is ensuring that they are not facing abuse or neglect. Self-autonomy and control over their own lives must be encouraged as much as possible while providing them with appropriate care and supporting a risk-free environment.
