AIMS This study identified factors associated with frequency of emergency department (ED) use for medical reasons among patients with substance-related disorders (SRD) in Quebec (Canada) for 2014-15. METHODS Participants (n = 4731) were categorized as: 1) low (1 visit/year), 2) moderate (2 visits/year), and 3) high (3+ visits/year) ED users. Independent variables included predisposing, enabling and needs factors based on the Andersen Behavioral Model. Multinomial logistic regression identified associated variables. RESULTS Factors positively associated with moderate and high ED use included adjustment disorders, suicidal behavior, alcohol-induced disorders, less urgent to non-urgent illness acuity, referral to local health community services centers (LHCSC) at discharge, and living in a materially deprived area. Factors positively associated with high ED use only included anxiety disorders, alcohol use disorders, drug use disorders, chronic physical illness, subacute problems, prior ED use for MD and/or SRD, prior LHCSC medical interventions, physician consultation within one month after discharge, living in very deprived or middle-class areas, and, negatively, being hospitalized for medical reasons in second ED visit. Moderate ED use only was negatively associated with alcohol intoxication and being referred to a GP at ED discharge. CONCLUSIONS Compared to low ED users, most high users with SRD were men presenting more complex and severe conditions. They visited ED mainly for subacute or non-urgent problems. Compared to low ED users, most moderate users had alcohol-induced disorders, less alcohol intoxication, and acute common MD. They visited ED mainly for non-urgent care. Diverse strategies should be implemented to reduce ED visits, targeting each group.

与物质相关疾病患者中急诊室使用率低，中和高相关的变量。

目的本研究确定了2014-15年度魁北克（加拿大）患有药物相关疾病（SRD）的患者因医疗原因而使用急诊科（ED）的频率相关的因素。方法参与者（n = 4731）被归类为：1）低（1次访问/年），2）中度（2次访问/年）和3）高（3次以上/年）ED用户。独立变量包括基于安徒生行为模型的易感性，促成因素和需求因素。多项式逻辑回归确定了相关的变量。结果与中度和高度ED使用正相关的因素包括适应障碍，自杀行为，酒精引起的疾病，对非紧急疾病的急性程度较不紧急，出院时转诊至当地卫生社区服务中心（LHCSC）以及生活在物质匮乏的地区区域。与高ED使用量呈正相关的因素仅包括焦虑症，酒精使用障碍，药物使用障碍，慢性身体疾病，亚急性问题，之前曾使用过MD和/或SRD的ED，过往的LHCSC医疗干预措施，出院后一个月内就诊，居住在非常贫困或中产阶级的地区，并且在第二次急诊就诊时由于医疗原因而住院。仅适度使用ED与酒精中毒呈负相关，并在ED出院时称为GP。结论与低ED使用者相比，大多数SRD高使用者是男性，他们的病情更为复杂和严峻。他们访问急诊科主要是为了解决亚急性或非急诊问题。与低ED使用者相比，大多数中度使用者有酒精引起的疾病，较少的酒精中毒和急性常见的MD。他们访问急诊科主要是为了提供非紧急护理。应该针对每个群体，采取不同的策略来减少急诊就诊。
