Annual Report 2014 of the National Preventive Mechanism 260. The installation of a video-conference system at the centres would enable the communication with the Administration of Justice in procedural formalities and would reduce the number of conveyances outside the centre, with all the advantages that this entails both for the minors and for the custody and security personnel. 261. It is considered necessary to point out that, in the best interest of the minor and to ensure his right to privacy, security and dignity, the Security Forces and Corps responsible for transfers should not wear a uniform and should use vehicles without official signs. 262. Along these lines, the security personnel working at these centres should consist of persons of both genders, particularly trained in peaceful dispute resolution and intervention in crises with the maximum respect to the rights of inmates, and that the use of force in their control be used when all other means have been exhausted and found unsuccessful and in the manner expressly authorised and described in the internal regulation of the centre. 263. With regard to healthcare, it is observed with particular concern that the legal term established for all minors, upon their admission to a centre, to pass a medical examination before 24 hours have elapsed is not always complied with. 264. It should be ensured that the medical attention received be provided maintaining the privacy of the minors and, if appropriate, ensuring that they receive adequate information in respect of the medical treatment that is to be given to them, in a manner such that they may give their informed consent, not obliging inmates to take medication or punishing them for failing to do so. Likewise, it would be advisable to set up forms for the inmate to sign his waiver to take the medication under his responsibility. 265. It is essential when applying certain medical treatments, when the minor is incapable either mentally or emotionally of understanding the scope of the action, to request consent from the legal representative of the minor, after granting the minor a hearing. In any case, in the case of an action of serious risk in the opinion of the professional, the parents should be informed and their opinion will be taken into account to make the relevant decision. 266. It is wished to bring attention to the clinical record of the inmates. It has been observed that, on occasion, centres are lacking a record and those that do have one do not use the same format for all patients, so that a clinical record form should be established conforming to that contemplated in Act 41/2002, of 14 November, organic act regulating patient autonomy and rights and obligations relating to clinical reporting and documentation. 94
