What the data can tell us
Supervised consumption sites offer harm reduction services that are central to the Government of Canada's response to the opioid overdose crisis. SCS data can provide early warning signals by detecting changes in:
- drug use and harms
- demographics of people using drugs
- types of drugs used
What we track
This page provides national data as well as data for each supervised consumption site (SCS). We don't include data from other sites, such as urgent public health needs sites (commonly known as overdose prevention sites).
We track:
- total number of visits to SCSs
- number of different clients
- client demographics (gender, age)
- number of drugs consumed by drug type
- number of health and social services provided within the SCS space
- number of referrals made to services provided outside of the SCS space
- number of overdoses and drug emergencies
- number of overdoses requiring the use of naloxone
- number of calls to emergency medical services (EMS)
Definitions of indicators
| Indicator | Definition and related measures |
|---|---|
| Drugs used |
Number of times a certain drug was consumed in the sites during the reporting period. This indicator is also presented as the percent of consumptions, which is the proportion of all drug consumptions involving a specific drug during the reporting period, expressed as a percentage. This shows what share of all drug uses involved a specific drug. |
| Emergency medical services |
Number of times EMS services (ambulance/paramedics) were called during the reporting period. |
| Law enforcement |
Number of calls made for police services, which could be for any number of reasons and are not necessarily related to a crime or violence. |
| New clients |
Total number of clients new to a particular SCS. This is reported as an average per month, which is the total number of new clients divided by the number of months in the reporting period. |
| Non-fatal overdoses |
Drug overdoses that took place in an SCS during the reporting period and which did not result in death. This indicator is reported as both a number and a rate. The rate reflects how often non-fatal overdoses happen relative to how many times drugs are used. It is expressed as the number of overdoses for every 1,000 consumptions. |
| Other medical services |
Number of other medical emergencies (not related to overdose events) that occurred during the reporting period. |
| Overdoses requiring naloxone |
Drug overdoses that required the use of naloxone (a fast-acting drug that can temporarily reverse the effects of opioid overdoses). This indicator is reported as both a number and a rate. The rate reflects how often overdoses requiring the use of naloxone happen relative to how many times drugs are used. It is expressed as the number of overdoses requiring naloxone for every 1,000 consumptions. |
| Referrals |
Referrals Referrals include any referral made to health or social support services not directly related to drug consumption. This can include:
Referrals to services onsite Any referral made to services that are offered within the same building as the SCS, but not in the SCS space (for example, an SCS which is attached to a community health centre). Referrals to services offsite Any referral made to services that are offered at a different location than the SCS or the building that the SCS is located in. Total referrals Any referral made to services that are offered in a connected onsite location, or offsite in a different location. |
| Services provided within the SCS |
Any health or social support services not directly related to drug consumption, that are offered within the SCS space (for example, a nurse holding a clinic within the space). This can include:
|
| Visits |
Total visits Average daily visits Average visits per month Average visits per site per month |
| Unique clients |
The number of different people using a site during the monthly reporting period. A person will only be counted once by a site each month, but the same person could be counted more than once when looking at data covering a period longer than one month. Average unique clients per month Average unique clients per site per month |
Data limitations
- Each SCS provides a standardized data report to Health Canada every month. Prior to March 2020, the reporting data wasn't completely standardized. Therefore, for the sites operating at any point prior to March 2020, we can't report on some data due to missing or inconsistent reporting, including:
- site-level data
- data on trends
- client demographics
- type of drug used
- calls for help
- services provided within the SCS
- There is a delay of about 2 months between when we receive data and when we post it. This allows us time for data entry and validation.
- Results for type of drug used are based on self-report and may not always accurately reflect what is actually being consumed and cannot tell us about any potential co-occurring substances within drugs being used. Additionally, individual SCS may interpret certain categories of drugs used differently, especially the categories of “speedball”, “unspecified opioid”, and “other substance.” For this reason, use caution when interpreting totals for each category.
- Individual SCS may interpret each category of services and referrals differently. For this reason, use caution when interpreting totals for each category.
