Gillick competence
Gillick competency applies mainly to medical advice but it is also used by practitioners in other settings. For example, if a child or young person:
- would like to have therapeutic support but doesn't want their parents or carers to know about it
- is seeking confidential support for substance misuse
- has strong wishes about their future living arrangements which may conflict with their parents' or carers' views.
Medical professionals need to consider Gillick competency if a young person under the age of 16 wishes to receive treatment without their parents' or carers' consent or, in some cases, knowledge.
If the young person has informed their parents of the treatment they wish to receive but their parents do not agree with their decision, treatment can still proceed if the child has been assessed as Gillick competent.
There is specific guidance for medical professionals on using Gillick competence - see case history and legislation.
Assessing Gillick competence
There is no set of defined questions to assess Gillick competency. Professionals need to consider several things when assessing a child's capacity to consent, including:
- the child's age, maturity and mental capacity
- their understanding of the issue and what it involves - including advantages, disadvantages and potential long-term impact
- their understanding of the risks, implications and consequences that may arise from their decision
- how well they understand any advice or information they have been given
- their understanding of any alternative options, if available
- their ability to explain a rationale around their reasoning and decision making.
Remember that consent is not valid if a young person is being pressured or influenced by someone else.
Children's capacity to consent may be affected by different factors, for example stress, mental health conditions and the complexities of the decision they are making. The same child may be considered Gillick competent to make one decision but not competent to make a different decision.
If you don't think a child is Gillick competent or there are inconsistencies in their understanding, you should seek consent from their parents or carers before proceeding.
In complex medical cases, such as those involving disagreements about treatment, you may wish to seek the opinion of a colleague about a child’s capacity to consent (Care Quality Commission, 2019).
Young people also have the right to seek a second opinion from another medical professional (General Medical Council, 2020).
Refusal of medical treatment
Gillick competency can be used when young people wish to refuse medical treatment.
However, if a young person refuses treatment which may lead to their death or severe permanent harm, their decision can be overruled. More information about this is available in the guidance for medical professionals in each UK nation - see case history and legislation.
Child protection concerns
The child's safety and wellbeing is paramount.
When you are assessing Gillick competency if you have any concerns about the safety of the young person you should check whether previous child protection concerns have been raised, and explore any factors that could put them at risk of abuse.
You must always share child protection concerns with the relevant agencies, even if this goes against a child's wishes.
