Insights
Illicit drug overdose deaths in British Columbia were analyzed, revealing common use of cocaine, opiates, and multiple substances. Further research into poly-substance use is recommended for public health interventions.
Area of Science:
- Public Health
- Epidemiology
- Toxicology
Background:
- Illicit drug overdose deaths (IDD) remain a significant public health issue in British Columbia, Canada.
- Previous peaks in IDD highlight the ongoing need for detailed analysis and intervention strategies.
Purpose of the Study:
- To examine the characteristics of illicit drug overdose deaths (IDD) in British Columbia in 2006.
- To analyze IDD by geographic location, decedent demographics, and identified substances.
Main Methods:
- Data on IDD were sourced from the British Columbia Coroners Office.
- Statistical analyses included Fisher's exact test, Pearson's chi-squared test, and Mann-Whitney U-test.
- Mortality rates were calculated using 2006 population estimates.
Main Results:
- A total of 223 IDD occurred in British Columbia in 2006, with 24% in Vancouver.
- Vancouver decedents were older and more likely to be male compared to those outside Vancouver.
- Cocaine (80.3%), opiates (59.6%), and poly-substance use (78.3%) were frequently identified in overdose deaths.
Conclusions:
- Collaboration with the Coroner's office facilitated a detailed analysis of IDD, including location and substance involvement.
- Cocaine, opiates, and poly-substance use were prominent factors in 2006 overdose fatalities.
- Further investigation into poly-substance use is crucial for developing effective public health interventions.
Background:
Illicit drug overdose deaths (IDD) relate to individual drug dose and context of use, including use with other drugs and alcohol. IDD peaked in British Columbia (BC) in 1998 with 417 deaths, and continues to be a public health problem. The objective of this study was to examine IDD in 2006 in BC by place of residence, injury and death, decedents' age and sex and substances identified.
Methods:
IDD data was obtained through the BC Coroners Office and entered into SPSS (version 14). Fisher's exact and Pearson's chi2 were used for categorical data; Mann-Whitney U-test for continuous variables. Rates were calculated using 2006 population estimates.
Results:
We identified 223 IDD in BC; 54 (24%) occurred in Vancouver. Vancouver decedents (compared to those occurring outside Vancouver) were older (mean age 43.9 vs. 39.2 years; p < 0.01) and more likely to be male (90.7% vs. 77.5%; p = 0.03). Provincially Aboriginal ethnicity was reported for 19 deaths; 13 (30.2%) of 43 females and 6 (3.3%) of 180 males (p = < 0.001).Cocaine was identified in 80.3%, opiates 59.6%, methadone 13.9%, methamphetamine/amphetamine 6.3%, and alcohol in 22.9% of deaths. Poly-substance use was common, 2 substances were identified in 43.8% and 3 or more in 34.5% of deaths. Opiates were more frequently identified in Vancouver compared to outside Vancouver (74.1% vs. 55.0%) p = 0.015.
Conclusion:
Collaboration with the Coroner's office allowed us to analyze IDD in detail including place of death; cocaine, opiates and poly-substance use were commonly identified. Poly-substance use should be explored further to inform public health interventions.
