- 53 - 120. As mentioned above, staffing levels remained insufficient and the recommendation contained in the CPT’s 2001 visit report had not been addressed. It is, therefore, not surprising that the fundamental components of an effective psycho-social rehabilitative treatment were underdeveloped, even absent, and that the treatment provided to psychiatric patients consisted essentially of pharmacotherapy. This situation can be attributed to the absence of suitably qualified staff and a lack of appropriate facilities. The CPT recommends that the Greek authorities take the necessary steps to fill the vacant health care posts within the hospital inter alia by filling all the posts of psychiatrist and by substantially revising the number of nursing staff and staff involved in therapeutic activities. In addition, the Greek authorities should ensure that all staff are provided with appropriate specialist training to carry out their duties professionally; further, a determined effort should be made to develop psycho-social rehabilitation treatment programmes. 121. Despite a high prevalence of drug addicts the two drug rehabilitation programmes covered only a limited number of patients. The CPT recommends the drug rehabilitation programmes be made available to all those patients in need thereof. It should also be noted that a significant number of patients interviewed by the delegation referred to the easy access to illegal drugs inside the hospital. A successful treatment of drug abuse cannot co-exist with the widespread availability of illicit substances, and the behaviour this engenders. 122. With regard to the introduction of a proper medical filing system, the CPT notes with dismay that there has been no progress in condensing the seven existing files into a single patient file, as recommended in the 2001 visit report. The inefficiency this caused was apparent to the delegation, as well as the fact that doctors found it difficult to obtain a clear overview of a patient’s status. Obviously, appropriate measures need to be taken to ensure the security of the medical files. Further, there was no internal policy on important medical issues, such as the use of chemical or mechanical restraints. Such a policy should be drawn up forthwith. The CPT recommends that the Greek authorities remedy these two problems.
