This study examined factors associated with health care use in an ethnically diverse Canadian sample of homeless adults with mental illness, a particularly disadvantaged group.
Baseline survey data were available from five sites across Canada for 2,195 At Home/Chez Soi demonstration project participants. Negative binomial regression models examined the relationship between racial-ethnic or cultural group membership (white, N=1,085; Aboriginal, N=476; black, N=244; and other ethnoracial minority groups, N=390) and self-reported emergency department (ED) visits and hospitalizations in the past six months and past-month visits to a medical, other clinical, or social service provider. Adjusted models included other predisposing, enabling, and need factors, based on Andersen's behavioral model for vulnerable populations.
Compared with white participants, black participants had a lower rate of ED visits (adjusted rate ratio [ARR]=.54, 95% confidence interval [CI]=.43-.69) and Aboriginal participants had a lower rate of medical visits (ARR=.84, CI=.71-.99) and a higher rate of visits to social service providers (ARR=1.54, CI=1.18-2.01). Participants in other ethnoracial minority groups had a higher rate of social service provider visits than white participants (ARR=1.44, CI=1.10-1.89). Access to a family physician, having at least high school education, and high needs for mental health services were associated with greater use of ED and medical visits and hospitalizations. Rates of ED and medical visits were lower with increased age and better physical health.
In a system of universal health insurance that prioritizes access to and quality of care, the presence of racial-ethnic disparities experienced by this vulnerable population merits further attention.
本研究调查了加拿大一个多民族的患有精神疾病的无家可归成年人样本(一个特别弱势的群体)中与医疗保健利用相关的因素。
来自加拿大五个地点的2195名“在家/在自己家中”示范项目参与者的基线调查数据可用。负二项回归模型研究了种族或文化群体成员身份(白人,N = 1085;原住民,N = 476;黑人,N = 244;以及其他少数族裔群体,N = 390)与过去六个月自我报告的急诊室就诊和住院情况以及过去一个月对医疗、其他临床或社会服务提供者的就诊之间的关系。基于安徒生针对弱势群体的行为模型,调整后的模型纳入了其他易患因素、促成因素和需求因素。
与白人参与者相比,黑人参与者的急诊室就诊率较低(调整后的率比[ARR]=0.54,95%置信区间[CI]=0.43 - 0.69),原住民参与者的医疗就诊率较低(ARR = 0.84,CI = 0.71 - 0.99),而社会服务提供者就诊率较高(ARR = 1.54,CI = 1.18 - 2.01)。其他少数族裔群体的参与者比白人参与者有更高的社会服务提供者就诊率(ARR = 1.44,CI = 1.10 - 1.89)。能看家庭医生、至少受过高中教育以及对心理健康服务有高需求与更多地利用急诊室、医疗就诊和住院相关。随着年龄增长和身体健康状况改善,急诊室和医疗就诊率降低。
在一个优先考虑医疗服务可及性和质量的全民医疗保险体系中,这一弱势群体中存在的种族差异值得进一步关注。
