10 UNITED NATIONS STANDARD MINIMUM RULES FOR THE TREATMENT OF PRISONERS (e) Determining the fitness of prisoners to work, to exercise and to participate in other activities, as appropriate. Rule 31 The physician or, where applicable, other qualified health-care professionals shall have daily access to all sick prisoners, all prisoners who complain of physical or mental health issues or injury and any prisoner to whom their attention is specially directed. All medical examinations shall be undertaken in full confidentiality. Rule 32 1. The relationship between the physician or other health-care professionals and the prisoners shall be governed by the same ethical and professional standards as those applicable to patients in the community, in particular: (a) The duty of protecting prisoners’ physical and mental health and the prevention and treatment of disease on the basis of clinical grounds only; (b) Adherence to prisoners’ autonomy with regard to their own health and informed consent in the doctor-patient relationship; (c) The confidentiality of medical information, unless maintaining such confidentiality would result in a real and imminent threat to the patient or to others; (d) An absolute prohibition on engaging, actively or passively, in acts that may constitute torture or other cruel, inhuman or degrading treatment or punishment, including medical or scientific experimentation that may be detrimental to a prisoner’s health, such as the removal of a prisoner’s cells, body tissues or organs. 2. Without prejudice to paragraph 1 (d) of this rule, prisoners may be allowed, upon their free and informed consent and in accordance with applicable law, to participate in clinical trials and other health research accessible in the community if these are expected to produce a direct and significant benefit to their health, and to donate cells, body tissues or organs to a relative. Rule 33 The physician shall report to the prison director whenever he or she considers that a prisoner’s physical or mental health has been or will be injuriously affected by continued imprisonment or by any condition of imprisonment.
