25 Selected topics from 2019 The role and procedures of the health service Medical personnel must not be involved in decisions to use coercive measures, such as using restraint beds.20 They are only responsible for safeguarding the patient's health and welfare in accordance with the 'primum non nocere' principle of preventing harm. The Nelson Mandela Rules set out detailed rules about the role of medical personnel in relation to persons deprived of their liberty who are placed in solitary confinement, isolation or subject to other similar interventions.21 Medical personnel should ensure regular medical checks of the inmates’ physical and mental health, and report adverse e ­ ffects to health.22 The Health Personnel Act Section 4 states that medical personnel must perform their work in accordance with the ­requirements of professional responsibility and diligent care. Medical personnel play a key role in relation to inmates placed in restraints, both because the decision is made on the grounds of self-harm and risk of suicide, and because being placed in restraints in itself poses a risk of injury. Inadequate supervision and medical follow-up of the inmates’ health while placed in restraint beds could be aspects of an evaluation that may result in a violation of Article 3 of the European Convention on Human Rights has taken place.23 The health risks posed by being placed in restraints means that a qualified and accessible health service with solid procedures for follow-up during and after the use of restraints is essential. For medical personnel to attend to their duties ­according to the Health Personnel Act, they must have in-depth knowledge of the risk of harm caused by the use of restraints. Half of the health services in prisons that have a restraint bed do not have dedicated procedures for their role and tasks when inmates are placed in restraint beds. Most prisons are also dependent on assistance from the local accident and emergency unit for large parts of the day when the prison health service is closed. Very often, inmates are placed in restraint beds in the evening and remain restrained throughout the night. In practice, the accident and emergency unit is rarely contacted, even when an inmate is placed in a restraint bed. A review of the supervision logs showed that, in about half of the cases, a doctor was not consulted in advance, or notified as soon as possible, as set out in the guidelines.24 Several of the supervision logs revealed that inmates spent many hours in restraint beds without being supervised by medical personnel.25 Prison officers also reported that doctors from the accident and emergency units were not very aware of the risks associated with placing people in restraint beds. As a result the prison officers would wait until the next day to notify medical personnel when prison health service staff were available.26 In the majority of the cases, the doctors from the accident and emergency units do not have previous knowledge of the patients. 20 The Mandela Rules, Rule 46 No 1. 21 The Mandela Rules, Rule 46 No 1, 2, 3. 22 The Mandela Rules, Rule 46 No 2. 23 Henaf v.
