Report on the Performance of Activities of the National Preventive Mechanism for 2016 Prison. Besides affecting maintenance of security, unfilled systematized job positions of judicial police officers, have negative impact on the availability of healthcare services; for example, when due to lack of police officers accompanying prisoners to external medical institutions, medical tests or specialist examinations arranged in advance must be postponed. Lack of officials also affects the quality of implementation of security measures for compulsory addiction treatment. Even though a positive step forward has been made towards intensification of activities in the Glina State Prison, if systematized job positions in the Treatment Department for Prisoners remain unfilled Due to unfilled systematized job – only 18 out of 36 positions are currently occupied – positions, healthcare departments of systematic treatment will remain impossible to all penal institutions are unable to conduct and special social-therapy department, ensure that every day of the week, where prisoners requiring substitution therapy are daily medications are distributed being treated, will be not be able to function. exclusively by healthcare workers. Many penal institutions do not keep recommended auxiliary records, which would provide insight into information on how much time it takes for the prisoner to be examined after having booked an appointment with the prison doctor, dentist or psychiatrist. For example, in Pula County Prison, if a prisoner is not examined on the day of filing the application, it expires and the prisoner must file a new one, which is unacceptable, since an application for a doctor’s appointment should be valid until check-up has been performed.

The reasons provided therein pertain to the question of security as well as to specific nature of medical check-ups performed in an external medical institution. Nevertheless, the issued warnings pertain to check-ups performed by prison doctors in the prison infirmary. However, even though individual security assessment is the first thing that must be taken into account, it is also important to protect the prisoner’s right to privacy as a patient. Therefore, it is essential to make technical adjustments to the outer side of the infirmary door or wall and enable visual supervision to judicial police officers, when this is necessary for the sake of security assessment. During our visits to penal institutions, prisoners usually expressed considerable dissatisfaction with diet menus that did not match their health requirements. As a result, we thus analysed all menus in Pula and Rijeka County Prison. In Pula County Prison, we were provided only with information on energy values for certain meals and for the entire daily menu, which is why it was impossible to perform a more detailed analysis or examination of this issue. There is only 12
