16 In the event of such a regime being imposed or applied on request, an essential safeguard is that whenever the prisoner concerned, or a prison officer on the prisoner's behalf, requests a medical doctor, such a doctor should be called without delay with a view to carrying out a medical examination of the prisoner. The results of this examination, including an account of the prisoner's physical and mental condition as well as, if need be, the foreseeable consequences of continued isolation, should be set out in a written statement to be forwarded to the competent authorities. 57. The transfer of troublesome prisoners is another practice of interest to the CPT. Certain prisoners are extremely difficult to handle, and the transfer of such a prisoner to another establishment can sometimes prove necessary. However, the continuous moving of a prisoner from one establishment to another can have very harmful effects on his psychological and physical well being. Moreover, a prisoner in such a position will have difficulty in maintaining appropriate contacts with his family and lawyer. The overall effect on the prisoner of successive transfers could under certain circumstances amount to inhuman and degrading treatment. 58. Health care services within prisons (including dietary matters and food in general) is, of course, an additional matter to which the CPT pays the closest attention. This is a vast subject, which the Committee hopes to explore in depth in a future general report. However, persons particularly interested in this subject can already refer to the relevant sections of the reports drawn up by the CPT following its visits to Austria, Denmark and the United Kingdom (as regards the publication of these reports, see paragraph 25). In this report, the CPT would only stress that it is highly desirable for prison medical services to be closely aligned with the mainstream of health care provision in the community as a whole. * * * 59. Finally, the CPT wishes to emphasise the great importance it attaches to the training of law enforcement personnel7 (which should include education on human rights matters - cf. also Article 10 of the United Nations Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment). There is arguably no better guarantee against the ill-treatment of a person deprived of his liberty than a properly trained police or prison officer. Skilled officers will be able to carry out successfully their duties without having recourse to ill-treatment and to cope with the presence of fundamental safeguards for detainees and prisoners. 60. In this connection, the CPT believes that aptitude for interpersonal communication should be a major factor in the process of recruiting law enforcement personnel and that, during training, considerable emphasis should be placed on developing interpersonal communication skills, based on respect for human dignity. The possession of such skills will often enable a police or prison officer to defuse a situation which could otherwise turn into violence, and more generally, will lead to a lowering of tension, and raising of the quality of life, in police and prison establishments, to the benefit of all concerned. 7 The expression "law enforcement personnel" in this report includes both police and prison officers.
