This essay provides a detailed reflection on the relationship between culture and health, specifically focusing on the case of a 54-year-old Torres Strait Islander patient diagnosed with Type 2 diabetes and showing signs of pre-Alzheimer's dementia. The author, a nurse at Thursday Island Hospital in Australia, utilizes the Purnell Model of Cultural Competence (PMCC) to analyze the cultural factors influencing the patient's health and treatment. The essay discusses the patient's symptoms, the challenges in providing culturally competent care, and the need for practice modifications to create a safe environment. The theoretical frameworks, including WHO's dimensions of health and the concept of indigeneity, are used to support the analysis. Furthermore, the essay emphasizes the importance of cultural knowledge, cultural competence, and cultural encounters in providing effective healthcare, addressing the impact of religious beliefs and social determinants on the patient's well-being, and proposing strategies to reduce disparities and promote health equity.
