The continued use of solitary confinement has sparked international public health and human rights criticisms and concerns. This carceral practice has been linked repeatedly to a range of serious psychological harms among incarcerated persons. Vulnerabilities to harm are especially dire for persons with preexisting serious mental illness ("SMI"), a group that is overrepresented in solitary confinement units. Although there have been numerous calls for the practice to be significantly reformed, curtailed, and ended altogether, few strategies exist to minimize its use for people with SMI and histories of violence against themselves or others. This case study describes the "Oregon Resource Team" (ORT), a pilot project adapted from a Norwegian officer-led, interdisciplinary team-based approach to reduce isolation and improve outcomes for incarcerated persons with SMI and histories of trauma, self-injury, and violence against others. We describe the ORT's innovative approach, the characteristics and experiences of incarcerated people who participated in it, its reported impact on the behavior, health, and well-being of incarcerated persons and correctional staff, and ways to optimize its effectiveness and expand its use.
