Event Description

The Windsor-Essex County Health Unit’s surveillance and monitoring system has identified an increase in opioid-related Emergency Department (ED) visits and substance use-related Emergency Medical Service (EMS) calls inclusively between June 27th and July 3rd of 2022.

Over this seven-day consecutive period, there were a total of nine (9) opioid overdoses reported by Windsor Regional Hospital, seven (7) of which involved fentanyl. These values exceed our two-year historical average by more than three standard deviations above the mean. Four (4) opioid non-overdoses were also reported by Windsor Regional Hospital during this same time period, three (3) of which involved fentanyl. Alongside the ED visits, there were also six consecutive days of substance use-related EMS calls flagged by the system between June 27th and July 2nd, with a total of fourteen (14) calls received during that period. As such, based on the information available, a public alert is warranted.

Partners involved in the WECOSS, including the WECHU, Windsor Regional Hospital, Essex Windsor-EMS, Erie Shores Healthcare, and Police Services, continue to monitor this increase and are working to understand more about these reported cases.
