The aim of this study is to conduct a population-level study on substance use treatment utilization among immigrants from Muslim-majority countries (MMC) and non-MMC, compared with Canadian-born individuals in Ontario.
A population-based, repeated measures cross-sectional study was conducted. Additionally, individuals with at least one contact with substance use services were followed. Negative binomial models were run to compare the rate ratio of the number of repeated healthcare visits per person per year of follow-up by subpopulation group. This study included three separate populations (Canadian-born, immigrants from MMC, and immigrants from non-MMC) residing in Ontario, Canada. All individuals residing in Ontario on the first day of each calendar year from January 2003 to December 2022 were included. Data were collected from three major sources: outpatient visits, emergency department visits, and inpatient hospitalizations.
In 2022, immigrants from MMC ( = 561,937) and non-MMC ( = 2,138,307) groups had lower substance-use service utilization across all service types compared with Canadian individuals ( = 12,178,607). Comparing 2022 to 2003, the most significant increase in utilizing hospitalization was for MMC immigrants (RR: 3.0; 95% CI: 2.1-4.4; < 0.01) and the lowest increase in outpatient service utilization was in MMC immigrants (RR: 1.8; 95% CI: 1.5-2.0; < 0.01). The rates of repeated service utilization among those who initiated contact with outpatient services in the MMC and non-MMC groups were significantly less than Canadian-born individuals.
Immigrants from MMC and non-MMC with substance use disorders may utilize service only at critical stages, thereby jeopardizing treatment success.
本研究旨在对来自穆斯林占多数国家（MMC）和非MMC的移民以及安大略省的加拿大本土居民进行物质使用治疗利用情况的人群水平研究。
开展了一项基于人群的重复测量横断面研究。此外，对至少与物质使用服务有过一次接触的个体进行了随访。运行负二项式模型以比较各亚人群组每人每年随访期间重复医疗就诊次数的率比。本研究纳入了居住在加拿大安大略省的三个独立人群（加拿大本土居民、来自MMC的移民和来自非MMC的移民）。纳入了2003年1月至2022年12月每个日历年第一天居住在安大略省的所有个体。数据从三个主要来源收集：门诊就诊、急诊科就诊和住院治疗。
2022年，与加拿大个体（n = 12,178,607）相比，来自MMC的移民（n = 561,937）和非MMC的移民（n = 2,138,307）组在所有服务类型中的物质使用服务利用率较低。将2022年与2003年进行比较，住院治疗利用率增幅最大的是MMC移民（RR：3.0；95%CI：2.1 - 4.4；P < 0.01），门诊服务利用率增幅最小的是MMC移民（RR：1.8；95%CI：1.5 - 2.0；P < 0.01）。在MMC和非MMC组中开始接触门诊服务的人群中，重复服务利用率显著低于加拿大本土居民。
患有物质使用障碍的来自MMC和非MMC的移民可能仅在关键阶段使用服务，从而危及治疗效果。
