Patient ethics can be defined as part of the system of medical ethical principles that focuses attention on the best interests of the patient. It is important to recognise the right of patient autonomy, where self-determination exists. This ensures that the healthcare professional is treating the patient or acting to prevent complications in a way that will provide the best result for that individual. This is often termed patient-centred care, which is discussed in further detail. This article aims to explain the need for ethics in a clinical setting, not only for the benefit of the patient but for the benefit of the healthcare professional and wider healthcare industry.
