- 49 provision of specialist medical care on a regular basis, the most urgent need being for a psychiatrist; Further, as regards Chios Judicial Prison, the Committee would like to receive confirmation of the recruitment of a general practitioner, on a half time basis, and at least one full-time qualified nurse as well as arrangements for regular visits by other medical staff, such as a dentist. More generally, the CPT recommends that a detailed needs assessment be carried out in all prisons, having regard to their particular characteristics, to determine the requirements in terms of health care staff. The results of the needs assessment should be communicated to the Committee, along with a plan for taking the necessary measures. 107. The findings of the delegation in the course of the visit highlighted the fact that in all the prisons visited (with the possible exception of Komotini Judicial Prison) there was a total lack of coordination or consultation among the various medical staff. The smooth operation of a health care service presupposes that doctors and nursing staff are able to meet regularly and to form a working team under the authority of a senior doctor in charge of the service. The CPT recommends that in each prison a senior doctor be appointed as the head of health care, with responsibility for managing the health care service and ensuring there is a regular consultation process among the staff. ii. medical screening on admission 108. For a fifth time the CPT is obliged to reiterate the importance of medical screening of prisoners on admission - especially at establishments which represent points of entry into the prison system. Such screening is indispensable, in particular in the interests of preventing the spread of transmissible diseases, suicide prevention and the timely recording of any injuries. 109. In none of the four prisons visited was the medical screening systematically carried out on every new arrival on the day of, or day after, their arrival. Many prisoners had not seen a doctor at all while others had had to wait for periods of a week or more, or until they were forced to see the doctor for a pain/illness. Further, in none of the prisons could the initial medical examination be considered as comprehensive, consisting merely of a few questions. The CPT recommends that every newly-arrived prisoner be properly interviewed and physically examined by a medical doctor as soon as possible after his admission. Save for exceptional circumstances, that interview should carried out on the day of admission, especially insofar as remand establishments are concerned. Such medical screening on admission could also be performed by a fully qualified nurse reporting to a doctor.35 35 The CPT has already commented that the relevant provisions of the Prison Law should be amended (cf. CPT/Inf (2002) 31, paragraph 91).
