32 npm annual report 2016 /observations and recommendations • In another prison, the Deputy-Ombudsman considered it positive that units had been equipped with locked mail boxes through which prisoners could send messages to the outpatient clinic. (Kylmäkoski) • The Deputy-Ombudsman encouraged a prison to take measures regarding urine sample collection facilities that do not have a one-way mirror between the supervisor and the person under supervision to make the situation easier and more comfortable for prisoners and staff alike. (Riihimäki) • One prison had no signs about CCTV monitoring in the visiting rooms or outside the visitor building of an open institution. (Suomenlinna) The Deputy-Ombudsman pointed out that people must be informed of the use of technical monitoring devices. Comment: The prison put up a notification of the monitoring. According to the prison, information had previously been provided orally. • Prisoners were not allowed to wear their own clothes during visits. Prisoners were also required to wear prisoners’ outfits in work activities and outside the prison (e.g. hospital visits). (Mikkeli) Comment: The Deputy-Ombudsman pointed out that the practice was not based on law. This also applies to the skirts worn by Roma prisoners (Oulu). Mikkeli Prison agreed to change its practices. Supervisory staff’s participation in the distribution of medicines • The office of a prison unit had a basket with medicines to be given to prisoners as needed. Warders do not have access to prisoners’ health records, which also include information on their medication. (Kylmäkoski) Prisoners can give the health care unit their written consent allowing the unit provide information on their medication to supervisory staff who distribute medicines. In the Deputy-Ombudsman’s view this would be a good practice in terms of patient safety and the legal protection of the warder distributing medicines.
