The right to consult a doctor - and not a doctor of their choice - is implemented via a medical service set up within the CRAs. Somatic medical availability in the strict sense is generally limited to half a day, daily from Monday to Friday. The rest of the time, detainees are seen by nursing staff. The investigators found that access to the medical department was, within some CRAs limited to one half hour per day and subject to a police filter, from the application being forwarded and assessment of their case. Intervention by psychiatrists or psychologists is only very rarely organised via an agreement and detainees' autonomy is even further reduced in this area. The question is important as, in addition to immediate healthcare, it can have an impact in revealing an illness whose treatment is not available in the country of deportation, which is a criterion liable to be an obstacle to deportation. 127 The CGLPL renews its recommendation in relation to updating the circular dated 7th December 1999 issued by the Ministry of the Interior and Health relating to healthcare for detainees: "The circular should, in particular, provide details that detainees so wishing may speak directly to healthcare providers without having recourse to an intermediary and that letterboxes should be set up, that a health consultation should be systematically set in place upon arrival at the centre by detainees both to enable possible contagious illnesses to be detected and to carry out a health check and enable an appropriate care regime to be set up, including by specialists". 128 Detainees have some freedom of circulation within a centre subject to restrictions provided for by internal regulations. These define accessible areas as well as opening times; they give the centre manager the powers to make any provision such as to guarantee security and public order including physically separating from other detainees any person initiating a public order problem or problems for personal safety of others. The CRAs usually have a room known as a "separation room" comprising a bed and sanitary arrangements (wash basin, tap and WC); detainees are locked up there and placed under surveillance 129 On a number of occasions, regrettable practices have been brought to the attention of the CGLPL of persons clearly suffering from behavioural problems being separated for a number of days. The CGLPL has also been notified about persons who, because they have been separated have not been able to claim their rights. It would therefore appear essential that the body responsible for legal assistance be notified of such a decision and be able, as appropriate, to make provisions such as to enable the person to effectively exercise their rights in particular where they have already started these procedures. As a result of numerous observations made by the CGLPL, the Ministry of Immigration published a circular dated 11th June 2010 relating to "standardising practices in force in CRAs". These require that measures taken in relation to isolation be entered in the detention register mentioning the grounds, the date and times of the start and end of these measures; they provide that the State Prosecutor is advised immediately of this measure. The CGLPL recalls that the procedures and the length of placing in isolation should be defined in the regulatory part of the CESEDA. Moreover these measures should be set out in a special, separate register specifying - in addition to the grounds, the times of the start 127 Please see Article 313-11 of the CESEDA.
