d) Use of the «isolation rooms» in strict observance of the applicable requirements of exceptionality and emergency. II This position has its origin in the visit held to the Hospital Magalhães Lemos, E.P.E. by a team of the National Preventive Mechanism (NPM)(23), in the past November 7th of the year 2014. In accordance with the scope of intervention of the NPM(24), several organisational aspects and practices in use for users subject to internment were assessed under the compulsive Act of Mental Health(25), namely in which regards use of constraints and medication protocols in place when no physician is present. The physical space for newly admitted patients was also assessed, with the purpose of analysing the conditions of privacy there. On the onset of this visit, a meeting was held with the clinical director, which provided several clarifications on the characterisation of the hospital and practices relating to involuntary admissions. The particular gravity of this measure seemed properly recognised by clinical professionals who collaboratively work to replace it with involuntary outpatient treatment, whenever the conditions allow. In particular regarding the use of restraints on patients at risk of inflicting injury to themselves or others, the grasp on aspects covered by formal parameterization was considered to be a barely enough. As this is one aspect that involves high potential for violation of the rights of patients, we call for consolidation and robust awareness in accordance with best practice of international and national guidelines, in particular those emanating from the General Direction of Health and the internal procedure of the institution. The absence of an autonomous specific record, to identify and characterise the restraints used made it difficult, on the day of the visit, to obtain data (quantitative and qualitative) on the use of restraints. These were later collected and shared. This is an opportunity for improvement, identified by the NPM, for the implementation of a specific record, independent and cumulative with the clinical process of patients, as now recommended. Notwithstanding the mentioned need to strengthen the guidelines on the use of restraints in patients, the practice in Hospital Magalhães Lemos, E.P.E., such as described (23)  In Portugal, the quality of National Preventive Mechanism has been attributed to the Ombudsman, through the Council of Ministers Resolution no. 32/2013, May 20th.
