CAN/HSO 22004:2021 Mental Health and Addiction – Public Review

The public review of HSO’s Mental Health and Addiction standard will take place between November 4th, 2021 and January 4th, 2022.

This is the opportunity for anyone to review and comment on the draft standard before it is published. HSO will incorporate applicable feedback into the final version of the standard with guidance from the Technical Committee overseeing the work. The standard will be reviewed in five years’ time or as part of an upcoming national standard. There will be future opportunities to change it as part of an ongoing process.

About the standard

CAN/HSO 22004:2021(E) Mental Health and Addiction addresses the provision of high-quality and safe mental health and addiction care and services. The standard is applicable to all health and social service organizations providing mental health and/or addiction services.

The standard is intended to be used as a tool to improve the quality, effectiveness and outcomes related to programs and services for people who experience mental health illnesses and addictions. This standard also aims to address barriers to care that people with mental health illnesses and/or addictions often face when trying to access services such as lack of timely, relevant support; stigma; and difficulty navigating multiple intersecting systems and sectors.

The standard follows the client’s health and wellness journey through the health and social service system, including in-patient and community-based settings.

Divided into seven sub-sections, CAN/HSO 22004:2021(E) Mental Health and Addiction will provide criteria and guidelines to assess the quality and safety of health and social service organizations providing mental health and/or addiction services. The sub-sections are:
• Population health, service planning, and design
• Prepared and competent teams
• Access to services
• Client rights and ethical considerations
• Timely, comprehensive, and coordinated services
• Medication and prescribing practices
• Quality improvement

Development process

CAN/HSO 22004:2021(E) Mental Health and Addiction is informed by the best available evidence and a Technical Committee made up of patients and family members, clinicians, health service administrators, health services stakeholders, and researchers.
