Consequently, the Committee considered that it would be useful to set out in the following paragraphs the standards which it has developed as regards the documenting and reporting of medical evidence of ill-treatment. Various related issues are also discussed. 73. It is axiomatic that persons committed to prison should be properly interviewed and physically examined by a health-care professional as soon as possible after their admission. The CPT considers that the interview/examination should be carried out within 24 hours of admission. This systematic medical screening of new arrivals is essential for various reasons; more specifically, if performed properly, it will ensure that any injuries borne by the persons concerned – as well as related allegations – are recorded without undue delay. The same procedure should be followed when a prisoner who has been transferred back to police custody for investigative reasons is returned to the prison; unfortunately, such transfers are still a common practice in some States visited by the CPT, and they can entail a high risk of ill-treatment (see also paragraph 80). Similarly, any prisoner who has been involved in a violent episode within prison should be medically screened without delay. In addition to prisons, there are other places of deprivation of liberty where persons may be detained for a prolonged period (i.e. more than a few days). This is the case, for example, of detention centres used to accommodate persons held under aliens legislation. Further, in a number of countries visited by the CPT, various categories of detained persons (e.g. administrative offenders; persons remanded in custody who are awaiting transfer to a prison or undergoing further investigation) can be held for prolonged periods in “arrest houses” or “temporary detention facilities”. Systematic medical screening of new arrivals should also be carried out in such places. 74. The record drawn up after the medical screening referred to in paragraph 73 should contain: i) an account of statements made by the person which are relevant to the medical examination (including his/her description of his/her state of health and any allegations of ill-treatment), ii) a full account of objective medical findings based on a thorough examination, and iii) the health-care professional’s observations in the light of i) and ii), indicating the consistency between any allegations made and the objective medical findings. The record should also contain the results of additional examinations carried out, detailed conclusions of specialised consultations and a description of treatment given for injuries and of any further procedures performed.
