• Therapeutic community approaches and open forensic psychiatry units should be considered for the implementation of the security measure of compulsory psychiatric treatment in a medical institution. • Solutions for the treatment and follow-up of forensic patients after the expiry of the security measures should be established – striving towards community-based support. Material conditions • When deprivation of liberty cannot be avoided, appropriate accommodation should be provided. National rules must provide that detention facilities and custodial institutions provide adequate accommodation for persons with psychosocial and/or intellectual disabilities. • Conditions of detention should be in line with international human rights standards. • Measures to decongest overcrowded facilities should be taken, where possible, through the application of non-custodial measures and outpatient treatment. • Adequate support and accommodations (physical, informational, attitudinal, medical, and other) should be available and accessible in all facilities where persons with intellectual and/or psychosocial disabilities are detained. • Cooperation with CSOs and other extramural services should be established to ensure that detainees with intellectual and/or psychosocial disabilities have access to support, treatment, and care. Treatment • Adequate numbers of specialised staff (medical staff, psychologists, psychiatrists) should be ensured in all facilities that detain persons with intellectual and/or psychosocial disabilities, as well as mandatory training for prison staff and other institutional staff interacting with persons with intellectual and/or psychosocial disabilities deprived of liberty. • All health and medical professionals (including psychiatric professionals) should obtain the free and informed consent of persons with intellectual and/or psychosocial disabilities, if needed through supported decision-making mechanisms, prior to any treatment; ensure there is a possibility to withdraw consent. 58
