Confirmed opioid toxicity deaths of Ottawa residents by ONS neighbourhood of incident

<p><strong>Date Created: </strong>December 2024<br /><strong>Update Frequency: </strong>Yearly<br /><strong>Last Reviewed: </strong>December 2024<br /><strong>Accuracy, Completeness, and Known Issues</strong>&nbsp;&nbsp;&nbsp;</p><ul><li>Data are from the "Suspect drug-related and confirmed opioid toxicity deaths in Ottawa Public Health" custom report provided by the OCCO.</li><li>Confirmed opioid toxicity deaths are deaths for which a coroner or forensic pathologist determined the cause of death to be drug toxicity with opioid involvement. These may include drug toxicity deaths involving multiple substances. Conclusions on cause of death may take several months to become available.</li><li>Deaths have been assigned to public health unit based on six-digit postal code of the residence of the decedent. If residence postal code was unavailable, the postal code of the incident location was used. If postal code of the incident location was unavailable, the postal code of the death location was used. This methodology aligns with how deaths are assigned in PHO's Interactive Opioid Tool.</li><li>The attribution of deaths to an ONS neighbourhood reflects the location of incident or death, based on postal code, and not necessarily the neighbourhood where the decedent resided. Postal codes that straddle more than one ONS neighbourhood are allocated to neighbourhoods based on the area of overlap between the straddled neighbourhoods. If there is no postal code information for the location of incident, the location of incident/death is not attributed to an ONS neighbourhood.&nbsp;</li></ul><p>&nbsp;</p><p><strong>Attributes:</strong></p><ul><li>ONS neighbourhood ID – the identification number for the Ottawa Neighbourhood Study (ONS) neighbourhood.</li><li>ONS neighbourhood name – the name of the ONS neighbourhood.</li><li>Cumulative number of confirmed opioid toxicity deaths – the cumulative number of confirmed opioid toxicity deaths of Ottawa residents based on the location of the incident.</li><li>Yearly average of confirmed opioid toxicity deaths – the cumulative number of confirmed opioid toxicity deaths of Ottawa residents divided by the number of years of data.</li><li>Average yearly rate (per 100,000 population) of confirmed opioid toxicity deaths – the average of the yearly rate (per 100,000 population) of confirmed opioid toxicity deaths of Ottawa residents. To calculate each neighbourhood’s annual rate, the total number of drug overdose deaths by ONS neighbourhood is divided by the neighbourhood population estimate for that year and then multiplied by 100,000. This gives us an annual neighbourhood rate per 100,000 population for each year of data and neighbourhood. For each neighbourhood, the annual rates are summed to create a cumulative neighbourhood rate, which is then divided by the number of years to create the average yearly rate for each neighbourhood.</li><li><p>Years – the range of years during which the deaths occurred.</p><p>&nbsp;</p></li></ul><p><strong>Data Steward: </strong>OPH Epidemiology Team<br /><strong>Data Steward Email: </strong><a href='mailto:[e-mail]' rel='nofollow ugc'>[e-mail]</a><br /><strong>Department or Agency: </strong>Ottawa Public Health<br /><strong>Branch/Unit: </strong>Epidemiology and Evidence<br />&nbsp;</p>
