- 43 Nevertheless, in the establishments visited, there was no trace of a prevention and treatment policy worthy of the name; in particular, there were no systematic prevention programmes and no practical advice was being provided on how to avoid the risk of HIV or hepatitis contamination posed by sharing needles19, and there were no psycho-socio-educational support programmes to assist inmates during withdrawal. Further, methadone substitution treatment initiated prior to admission was discontinued following arrival in prison. The CPT is also concerned to note that nursing staff had received no training in drug abuse prevention and treatment. In most cases, they acknowledged their total incompetence in such matters, with the exception of a few persons recruited for the drug treatment centre at Thebes who had been posted at Korydallos pending the opening of that centre. 98. The CPT recognises that providing assistance to persons who have drug-related problems is far from being a straightforward matter, particularly in a prison setting; there is no simple or single answer as regards the approach to be followed. However, the CPT considers that prevention of drug abuse should be vigorously pursued and should aim at both demand and risk reduction. Admission to prison is a privileged opportunity to address a person's drug-related problem and it is therefore important that suitable assistance is offered to all persons concerned; consequently, appropriate health-care must be available in all prisons and not only in those establishments with special drug treatment centres. The assistance offered to such persons should be varied, combining genuine medico-psycho-socio-educational detoxication programmes with substitution programmes for opiate-dependent patients who are unable to stop taking drugs. Finally, all health-care staff (and prison staff generally) should be given specific training on drug-related issues. The CPT recommends that a strategy be drawn up for the provision of assistance to all prisoners with drug-related problems, in the light of the above remarks. c. the Prison Hospital 99. As had been the case at the time of previous visits, in view of its staffing level and medical equipment, the Prison Hospital cannot be described as a fully-fledged hospital (cf. CPT/Inf (2001) 18, Part I, paragraph 162). Further, the transfer of patients in need of hospital care to an appropriate establishment in the community continued to pose problems; no progress appeared to have been made on this point since the previous visit. Accordingly, the CPT reiterates the recommendation made following the 1997 visit, namely that the Prison Hospital be resourced as a hospital in the true sense of the term or, when appropriate, ready access to fully-equipped hospital services elsewhere be guaranteed. 19 Cf. in this connection, Article 29, paragraph 4, of law 2776 of 22 December 1999.
