Is there a problem?
• Harm can occur in numerous ways
• Populations are very difficult to access and understand

• Context at that time
• Malaria / Polio / Influenza
‘The careful watchfulness over the distribution and
trends of occurrence through the systematic
collection, consolidation, and evaluation of
mortality and morbidity’
Purpose
1) Identify public health problems
• Communicable disease / Population Exposures
2) Stimulate public health intervention
• Information to plan, set priorities and evaluate the effects of public
health programs
3) Suggest hypotheses for epidemiological research

Indicator based surveillance
• Passive / Active / Sentinel Surveillance
• Traditional Sources of Illicit Drug Intelligence:
• Canadian Community Health Survey
• Canadian Alcohol and Drug Use Monitoring Survey
• Ontario Student Drug Use and Health Survey
• Coroners Reports
Event Based Surveillance
• Organized and rapid capture of information about events
that can be a risk to public health.
• Data is usually from Non-traditional sources
• Detect events that occur in populations not able to access
formal channels for reporting
• Direct Information from witnesses of real-time events
• Poison and tele-health services
• Indirect Information
• Communication channels
• Social media or established routine alert systems
• Information channels
• news media, public health networks

CCENDU Surveillance
• Canadian Community Epidemiology Network on Drug Use
• Investigate reported emerging issues related to drug use
• Communicate alerts and bulletins on topics of immediate concern
• Inform communities on lessons learned in responding to local drug
use issues
• Alerts / Bulletins
• June 2013 – Feb 2015 – 3 Alerts on Non-Pharmaceutical Fentanyl
• Sept 2014 – Drug-related Harms at Canadian Music Festivals​

Background. In early 2006, government and media sources reported that crime syndicates were mixing fentanyl with heroin. This was
followed by an increase in heroin overdoses and opiate-related deaths. The most recent fentanyl outbreak illustrated the need for identifying
and establishing effective and responsive real-time surveillance tools to monitor drug overdoses in the United States. Objective. In this
study, poison call center data from Illinois were evaluated to determine whether the data could have detected the outbreak that occurred in
Illinois in early 2006 and whether it could be used for real-time surveillance. Methods. For this analysis, a two-step approach was used to
analyze potential heroin-related calls. First, the data were analyzed retrospectively to identify whether any significant temporal shifts occurred,
then a prospective analysis was conducted to simulate real-time surveillance. Results. Between 2002 and 2007, there were a total of 1,565
potential heroin-related calls, and the calls increased by 63.6% in 2006 compared to 2005. In the prospective analysis, the principal model
would have identified the outbreak in March 2006. Conclusions. If there had been a real-time surveillance program using poison center data,
the outbreak would have been identified 1 month before the initial postmortem reports to the Centers for Disease Control and Prevention at the
end of April 2006. Poison center data provide the potential for an earlier warning system than postmortem data sources, because the reports are
usually made within hours of the exposure. Poison center data can be effectively used to monitor heroin-related exposures.

overdoses and opiate-related deaths from medical examiners.5 The largest number of reported deaths occurred in
Chicago.5 Fentanyl is an opiate with a far lower effective
dose and lethal dose than heroin. In opiate-naïve individuals,
the minimum lethal dose of heroin has been reported to be as
low as 10 mg6–8 compared to approximately 0.25 mg for fentanyl.8,9 There are various fentanyl analogues found in street
drugs, but the most commonly reported analogues are
a-methylfentanyl and 3-methylfentanyl.10

fentanyl abuse have also been reported in Finland and Russia.15
The most recent fentanyl outbreak illustrated the need for
identifying and establishing effective and responsive realtime surveillance tools to monitor drug overdoses in the
United States.5 All previous reports of fentanyl overdoses in
the United States have relied upon postmortem data. Although
information about deaths is important, there is a greater
reporting lag between the overdose
