-8Apart from that, therapeutic care for the patients can only be described as embryonic. Admittedly, efforts had been made in the units to provide for certain activities (behavioural programme for learning to perform everyday life activities, occupational therapy, physiotherapy, musical therapy, sport and other forms of recreation, sometimes outside the hospital), but they were provided on an irregular basis and could only be offered to a rather limited number of patients. Furthermore, some units had no occupational therapy or physiotherapy activities and in one the therapeutic programme had come to an end when the member of staff responsible left. As regards individual activities, the situation was the same as in 1993 and the delegation found no sign of a therapeutic programme sufficiently elaborated and structured to deal with psychomotor and mental handicap. The delegation observed that there was a large number of patients in need of sustained care of this kind. The main reason for this situation is the lack of therapeutical oriented and trained staff. However, it also emerged from discussions with the hospital staff that the therapeutic efforts made in recent years had mainly benefitted the external services and the child guidance centre which were said to have programmes not available at the hospital. This policy was in particular intended to avoid hospitalisation as far as possible. While recognising the importance of this aim, which deserves to be encouraged, the CPT nonetheless points out that it must not be pursued to the detriment of the quality of treatment offered to the patients in the hospital. 19. In the light of the foregoing, the CPT recommends that the Greek authorities intensify their efforts to develop substantially differentiated treatment activities using the full range of therapies (somato-, psycho-, socio- and occupational therapy). In this respect, it refers to the recommendation in paragraph 13 above. 20. In this connection, the CPT also points out that the conduct of satisfactory therapeutic programmes largely depends on a policy of differentiating patients according to their pathology and state of development. The delegation found that there was room for improvement in this respect. This was particularly flagrant in the so-called emergency unit, where there were patients requiring urgent psychiatric treatment, patients no longer in the acute phase and patients whose pathologies did not necessitate placement in an intensive care unit. The CPT would like to receive the Greek authorities' comments on this point. 21. The CPT would also indicate that the delegation was not persuaded that all patients whose state of health so permitted were allowed out daily into the open air in the exercise or recreation areas around the pavilions/units. This was brought to the attention of the Chairperson of the Administrative Board, who indicated that she would take immediate action accordingly. The CPT would like to receive confirmation of the measures taken in this respect. 22. As regards the supervision of the state of physical health of patients, the CPT would like to stress that during the 1996 visit its delegation found that this was satisfactory and that patients benefitted from regular medical controls which were duly recorded in the medical files. In this context, the CPT would like to know whether the hospital authorities have developed a preventive policy against transmissible diseases (e.g. hepatitis).
