- 44 d. the psychiatric unit 100. The CPT has noted with satisfaction that, since the 1999 visit, the medical staff at the psychiatric unit had been increased by one full-time psychiatrist, and that there was a round-theclock medical presence. However, despite this reinforcement, health-care staffing was still well below the minimum required for the unit to function properly, especially in view of the fact that overcrowding had increased since the previous visit: 205 patients (182 in 1999) for a capacity of 140 places. It is therefore not surprising that little had changed as compared to the situation found during previous visits as regards activities for patients: very few activities were offered to them, and most patients were permanently idle. The unit's health-care staff expressed regret that, due to lack of time and staff resources, they could not develop group therapy programmes and offer occupational therapy adapted to the different types of pathology encountered. The CPT recommends that the Greek authorities step up their efforts to strengthen the health-care team at the psychiatric unit, in order to enable it to implement proper health-care programmes, including a wide variety of rehabilitation and therapeutic activities. 101. There were numerous registers, files and forms containing patients’ medical data, as well as the observations of doctors and nurses. However, there were no personal medical files with the full medical details of each patient (cf. also paragraph 92). As a result, several sources had to be consulted in order to determine a given patient’s medical history. The CPT recommends that steps be taken to remedy this problem. Further, the nursing register was signed every morning by the psychiatric unit's administrative director, who therefore had access to the patients’ medical data. The CPT recalls its recommendation about the principle of confidentiality (cf. paragraph 93 above).
