18 other things, the length of stays in the security cells and that, in some cases, inadequate administrative decisions had been made. Some prisons have now obtained clothing that should not be possible to use for self-harm by twisting or tearing. This is an important measure to ensure that inmates do not have to be naked in the security cell. At the same time, these clothes can be perceived as stigmatising, unpleasant and an encroachment in itself, and they should therefore only be used in situations involving a concrete suicide risk. Apart from in this type of situation, inmates should have their own or other ordinary clothes from the institution. " It is also emphasised in several of the Parliamentary Ombudsman’s reports that stays in security cells constitute a particularly invasive form of solitary confinement " Regular supervision and regular conversations that prevent people deprived of their liberty from feeling isolated and helpless are important measures to reduce the risk of suicide and of aggravating mental illness. It is also emphasised in several of the Parliamentary Ombudsman’s reports that stays in security cells constitute a particularly invasive form of solitary confinement. Reference was made to existing knowledge that isolation can increase the risk of suicide, self-harm and the development of serious mental illness. The NPM’s experience to date indicates that the risk of serious self-harm and suicide is among the most commonly cited grounds for administrative decisions placing someone in a security cell. This gives cause for concern, given the negative effect of solitary confinement on inmates’ NORWEGIAN PARLIAMENTARY OMBUDSMAN National Preventive Mechanism against Torture and Ill-Treatment ANNUAL REPORT 2015 mental health. A review of supervision logs kept for security cells revealed instances in several prisons whereby inmates reacted to the situation by becoming apathetic, by undressing, by urinating on the floor and walls or by attempting to self-harm. Using a restraint bed Using a restraint bed is one of the most invasive measures that can be legally used on someone. Like other coercive measures, this measure is intended to prevent an acute situation and is never to be used in connection with treatment or as punishment. In contrast to the correctional services, where health personnel are not to be involved in decisions to use a restraint bed, in mental health care it is health personnel who decide and implement the use of a restraint bed for committed patients. The unique aspects of the role of health personnel in relation to people deprived of their liberty are discussed in a separate article (see page 23). The fact that health personnel both treat and implement the use of coercive measures creates special challenges for relations with people deprived of their liberty and reinforces the need for control mechanisms. Supervisory commissions have been appointed for mental health care institutions to review the use-offorce records, which include the use of restraint beds, and to check that the use of such measures has a legal basis and is properly documented. Hospitals are urged to ensure that administrative decisions to use restraint beds apply for the shortest possible time. In mental health care, people who are restrained using a restraint bed can also be forced to take short-acting medication. The review of useof-force records during visits to mental health care institutions revealed that the use of restraint beds is often combined with injections of short-acting medication.
