摘要
简介：急诊科（EDs）是药物使用者（PWUD）的重要卫生保健接入点，但对于COVID-19大流行的发作是否与阿片类药物相关急诊表现的变化有关，我们知之甚少。我们调查了(1)在艾伯塔省，COVID-19大流行的爆发是否与阿片类药物相关的急诊就诊平均率的变化有关；(2)不同地区的COVID-19病例率不同。方法：我们进行了最大似然中断时间序列分析，比较“大流行前时期”（2019年3月3日至2020年3月1日）和“大流行时期”（2020年3月2日至2021年3月14日）阿片类药物相关急诊科就诊情况。结果：大流行前和大流行期间，阿片类药物相关急诊科就诊人数分别为8883例和11 657例。COVID-19大流行的发生与阿片类药物相关的急诊科就诊增加有关（埃德蒙顿：IRR = 1.37, 95% CI: 1.30- 1.44, p < 0.05；卡尔加里：IRR = 1.14, 95% CI: 1.07-1.20, p < 0.05；其他卫生区：IRR = 1.14, 95% CI: 1.07-1.21, p < 0.05）。变化的COVID-19病例数与各地区阿片类药物相关急诊科就诊率的变化不一致。结论：与COVID-19大流行发病相关的阿片类药物相关急诊科就诊增加与阿尔伯塔省COVID-19病例患病率无关。
The relationship between COVID-19 and opioid-related emergency department visits in Alberta, Canada: an interrupted time series analysis.
Introduction: Emergency departments (EDs) are important health care access points for people who use drugs (PWUD), but little is known about whether the onset of the COVID-19 pandemic was associated with changes in opioid-related emergency presentations. We investigated whether (1) the onset of the COVID-19 pandemic was associated with any change in average rates of opioid-related ED visits in Alberta; and (2) this varied across regions with different COVID-19 case rates.
Methods: We conducted maximum-likelihood interrupted time series analyses to compare opioid-related ED visits during the "prepandemic period" (3 March 2019-1 March 2020) and the "pandemic period" (2 March 2020-14 March 2021).
Results: There were 8883 and 11 657 opioid-related ED visits during the prepandemic and pandemic periods, respectively. The onset of the COVID-19 pandemic was associated with an increase in opioid-related ED visits (Edmonton: IRR = 1.37, 95% CI: 1.30- 1.44, p < 0.05; Calgary: IRR = 1.14, 95% CI: 1.07-1.20, p < 0.05; Other health zones: IRR = 1.14, 95% CI: 1.07-1.21, p < 0.05). Changing COVID-19 case counts did not correspond with changing rates of opioid-related ED visits across regions.
Conclusion: The increase in opioid-related ED visits associated with the onset of the COVID-19 pandemic was unrelated to COVID-19 case prevalence in Alberta.
