Monthly Surveillance

Effective April 1, 2017, all Ontario hospitals with emergency departments are required to report all cases of opioid poisonings in the emergency department within one week of the occurrence. These reports are summarized on a weekly basis by the Ontario Ministry of Health and Long-Term Care. In 2019, from January to June, there have been 345 opioid poisoning emergency department visits at hospitals in Simcoe Muskoka, which was substantially higher than the 248 visits to Simcoe Muskoka hospitals from January to June in 2018; however, opioid poisoning emergency visits in July to September were down compared to previous months in 2019 and were lower than July to September of 2018. These data are considered preliminary and are subject to change.

Suspected overdose emergency department visits are also being tracked by the health unit and reported on a weekly basis in this syndromic surveillance report. These are not confirmed opioid overdoses; however, increases in suspected overdose visits can be an early warning for surges in opioid-related overdoses.
