The use of community treatment orders in people with substance induced psychosis

The community treatment order (CTO) is a legally mandated approach to community based psychiatric care that has been in existence for over 20 years in the Canadian province of Saskatchewan. Changes to legislation of CTOs implemented in 2015, has resulted in bolstered use of this approach to treat substance induced psychosis (SIP). Treatment plans implemented with the use of CTOs in the present study include pharmacotherapy, in the form of long-acting injectable antipsychotics (LAI-AP). The purpose of this retrospective, observational study was to determine whether there is a benefit for the use of a CTO with LAI-AP to mandate treatment for individuals diagnosed with SIP, and rates of both readmission to hospital, and presentation to emergency departments. We observed that individuals diagnosed with SIP and assigned a CTO that included a LAI-AP demonstrated a significantly lower rate of presentations to emergency departments and a lower rate of readmissions to hospital in the first one year following diagnosis, compared to those diagnosed with SIP and not assigned a CTO. Our results suggest that use of legally mandated treatment in this diagnostic group may ease both fiscal and human resource burdens on the healthcare system. Our finding may also assist when planning treatment pathways and services for people with a diagnosis of SIP.
