IMCAs commonly support individuals who lack the capacity to make critical decisions about their medical treatment, accommodation, or long-term care arrangements. This might involve attending meetings with medical or social care teams, reviewing case documentation, and ensuring the person's wishes and best interests are fully represented. The role often involves liaising with healthcare professionals, local authorities, and sometimes the individual's family or friends. By handling sensitive, complex situations, IMCAs play a crucial part in safeguarding the rights of people who cannot advocate for themselves.
