Best-Interest Decision-Making and Advocacy

Best-interest decision-making applies when an adult cannot make a specific decision and someone must decide on their behalf.

In England and Wales this is governed by the Mental Capacity Act 2005. Other parts of the UK use different legal frameworks, but the practical safeguarding approach is similar: involve the adult as much as possible, avoid assumptions about their preferences, and choose the least restrictive option that meets their needs and keeps them safe.

For clinical pharmacy staff, medicines decisions often affect discharge planning, ongoing treatment, and risk. Disagreements can arise between professionals and relatives. A best-interest decision is not the same as following family wishes, choosing the easiest service option, or deferring to whoever is most vocal.

It should be centred on:

• the adult's values
• their past and present wishes
• their clinical needs
• the least restrictive safe option

Why Advocacy Matters

Adults who struggle to communicate, who lack support, or who are overshadowed by others may need independent advocacy so their views are heard and their rights protected. Advocacy is particularly important where there is disagreement, possible coercion, complex discharge planning, or concern that the adult's perspective is being overlooked. At Level 3 you do not usually instigate formal legal processes, but you must recognise when advocacy or a formal best-interest process is needed.

A best-interest decision is not simply a family decision or a professional preference: it must stay focused on the adult, their rights, and the least restrictive safe option.

Deprivation of Liberty and Restrictive Care

Some care or treatment arrangements can be restrictive enough to amount to a deprivation of liberty. In England and Wales the Deprivation of Liberty Safeguards (DoLS) operate within the Mental Capacity Act for adults who lack capacity to consent to care or treatment in hospitals or care homes. Other UK nations have different procedures, so follow local mental capacity, adult protection, and safeguarding guidance.

Clinical pharmacy staff do not usually authorise a deprivation of liberty, but they may spot warning signs during hospital pharmacy work, care-home reviews, discharge planning, medicines optimisation, or prescribing. Warning signs include an adult who lacks capacity being under continuous supervision and control, not being free to leave, repeated restraint or sedation used to manage behaviour, or medicines being used in a way that appears to restrict freedom rather than address a reviewed clinical need.

If an adult lacks capacity to consent to care arrangements and appears to be under continuous supervision and control and not free to leave, this may raise deprivation-of-liberty concerns and should be escalated through the correct local route.
