Report on the Performance of Activities of the National Preventive Mechanism for 2017 case of high security prisons and the Lepoglava State Prison, enough treatment officials of relevant professions have to be provided for (psychologists, social pedagogues, social workers) since these prisons accommodate prisoners serving long-term prison sentence, high-risk prisoners and recidivists. As a rule, recidivists are not separated from prisoners serving their first sentence. This is not in line with the Execution of Prison Sentence Act (hereinafter: EPSA). Plus, such a practice makes treatment work even more difficult. Treatment officials usually talk to prisoners without judicial police officers being present. In some penal institutions (e.g. the Glina State Prison) each ward includes a special room for this purpose and generally, the conversations are enabled for all prisoners who apply. This is not the case in small penal institutions, e.g. the Karlovac County Prison, in which treatment officials have to talk to the prisoners in the judicial police’s dining room. Treatment work is difficult due to the insufficient treatment staff - in some penal institutions available treatment officials cannot cover the minimum conditions of work. This fact is even more exacerbated by inappropriate accommodation conditions and practice whereby, as a rule, recidivists are not separated from the prisoners serving their first sentence. Lack of treatment staff has negative effects on their presence in prison wards and prisoners often complain that their talks are too short. In some prisons, e.g. the Bjelovar County Prison, prisoners on remand were not even aware of the fact that they can apply to have a talk with the treatment official. On the other hand, in the Zadar County Prison, they are invited to such meetings immediately upon their arrival. Such a proactive approach represents a good practice example, also applied by the treatment official of the Dubrovnik County Prison. Compared to other penal institutions, security measures of compulsory psychiatric treatment and compulsory addiction treatment are much more easily implemented in the Glina State Prison given a full-time employed psychiatrist. Available free-time activities are not diverse. Objective factors come into play in terms of their organization (insufficient premises, poorly equipped workshops, lack of brushes and paints, computers are in poor condition etc.). Some prisons do not even ensure organized free-time activities so persons deprived of liberty have to take initiative to organize them on their own, for example in the Bjelovar County Prison. Apart from managing treatment groups of prisoners, treatment officials carry out special programmes established within individual programmes of execution of prison sentence, depending on the assessment of prisoners’ criminogenic risks and treatment needs. For instance, 25% of prisoners in the Lepoglava State Prison are involved in different special programmes, such as modified clubs of treated alcoholics, treated addicts, PTSD treatment etc. Yet, due to the data confidentiality issues in terms of information that they might disclose during these meetings, some prisoners refuse to take part in programmes managed by treatment officials who are obliged to report serious disciplinary breaches, so prisoners might think that these programmes are not very useful since they cannot speak up openly. Due to the lack of treatment staff, some prisons, for instance, the Bjelovar County Prison, do not organize special programmes that require group work. Others (the Karlovac County Prison) do not 11
