This case study analyzes the ethical and legal complexities surrounding the care of Peter Smith, an 82-year-old patient with dementia, focusing on the application of his Advanced Health Directive (AHD). The analysis highlights issues arising from Peter's overnight agitation and aggression, his daughter Mary's role as Power of Attorney, and the ethical dilemmas related to treatment for a Urinary Tract Infection (UTI). The study examines the legal requirements under the Medical Treatment (Health Directions) Act 2006 and the Public Health and Wellbeing Act 2008, particularly in the context of Queensland's guardianship system. It discusses Mary's responsibilities as Statutory Health Attorney, her options through Queensland Civil and Administrative Tribunal (QCAT) and the Community Visitor Program, and the application of least intrusive treatment options. The study emphasizes the importance of Mary's decision-making process, the consultation with Peter's GP, and the effective use of oral antibiotics for UTI treatment, aiming to balance Peter's wishes with his medical needs. This assignment highlights the importance of ethical and legal considerations in patient care, particularly when dealing with patients with impaired decision-making capacity.
