- 34 65. The CPT’s delegation observed that medical confidentiality at Corfu, Korydallos Men’s and Nigrita Prisons remains a serious concern. For example, at Korydallos Men’s Prison, a prisoner in each wing collected requests from the inmates to see a doctor or a nurse, and he often helped the other prisoners to write the application. In the health-care unit, the prisoners are seen in open spaces, with custodial staff, other patients and inmate personnel present. There is no privacy when the prisoners talk to the health-care workers. Furthermore, the inmates working in the health-care unit have access to all medical files. Indeed, the job of the prisoners working in the health-care unit in four of the five prisons visited was specifically to administer the medical files. The CPT reiterates its long-standing recommendation that the Greek authorities take the necessary steps to guarantee medical confidentiality both of consultations and of medical data. This necessitates recruiting additional nurses as recommended above (see paragraph 60). 66. As regards substance use and the programmes in place to address it, the CPT’s delegation found that a similar situation to that described in the report on the 2019 visit pertained in the prisons visited.37 The Centre for the Treatment of Drug-dependent Persons (KETHEA), provides psychosocial counselling and motivational support for prisoners, but without any opioid agonist treatment. Moreover, the number of counsellors remained far too low: for example, there were only four such counsellors at Korydallos Men’s Prison. As regards the Organisation Against Drugs (OKANA), it still cannot provide any opioid agonist therapy within prison which is a serious deficiency given the high level of need for such a treatment among prisoners. More generally, psychiatrists met in prison who work with detained persons with drug addiction problems again highlighted the lack of interpretation services to ensure clear and accurate communication with patients. 67. The CPT considers that prison provides an opportunity to address drug use concerns prior to inmates returning back into the community. The assistance offered to prisoners with drug-related problems should be varied; detoxification programmes with substitution treatment for drugdependent patients should be combined with genuine psycho-social and educational programmes. The setting up of a drug-free wing in prisons for certain categories of prisoners, inter alia those having completed treatment programmes prior to or during imprisonment, can be positive, as the experience from Korydallos Prison demonstrates. Further, all health care staff and, more generally, prison officers should be given specific training on drug-related issues. Effective throughcare in partnership with community-based agencies and organisations addressing drug-related issues should also be put in place. Currently, there are elements of this assistance through KETHEA and OKANA present in the larger prisons visited. However, there is a need to expand their work and to develop a comprehensive approach towards substance use in prison as part of a national strategy. The goals should be inter alia: eliminating the supply of drugs into prisons; dealing with substance use problems through identifying and engaging drug users, providing them with treatment options and ensuring there is appropriate throughcare; developing standards, monitoring and research on drug issues; and the provision of staff training and development. 37 See CPT/Inf (2020) 15, paragraphs 53 and 54.
