摘要

目的早期精神病干预(EPI)项目在早期发现和治疗精神病方面发挥着至关重要的作用,但在可及性方面仍然存在差异。本研究旨在评估加拿大多伦多市EPI项目的空间可达性,并探讨可达性与社区边缘化指标之间的关系。方法采用浮动集水区和两步浮动集水区方法进行地理空间分析,考察了多伦多158个社区的EPI项目地点、人口普查估计以及区域级边缘化数据。利用空间回归模型估计边缘化因子与空间可达性之间的关系。结果平均而言,最近的EPI项目距离任何给定社区的中心4公里(范围为0.8-11公里),在全市范围内存在差异。在一些社区中观察到聚类,表明空间可达性较好,而其他社区则面临较低的可达性。全空间回归模型显示,住房和居住边际化程度的提高以及物质资源边际化程度的提高与更好的获取途径有关。结论我们确定了EPI服务的空间可达性较差的社区。以前发现的一些与精神病风险相关的社区一级边缘化指标也与更好的空间可达性有关。值得注意的是,多伦多的扩大免疫服务可能位于最需要它们的地方。该研究强调了地理空间分析的重要性,以确定和解决地理距离作为获取差异的潜在来源。

A Geospatial Analysis of Early Psychosis Intervention Programs in Toronto, Canada: Une analyse géospatiale des programmes d'intervention précoce en cas de psychose à Toronto, au Canada.

ObjectivesEarly psychosis intervention (EPI) programs play a crucial role in detecting and treating psychosis early, yet disparities in access persist. This study aimed to assess the spatial accessibility of EPI programs in Toronto, Canada, and to explore the association between access and indicators of neighbourhood-level marginalization.MethodsWe conducted a geospatial analysis using floating catchment area and two-step floating catchment area methods, examining EPI program locations, census population estimates for the 158 Toronto neighbourhoods, and area-level marginalization data. Spatial regression models were used to estimate the association between marginalization factors and spatial accessibility.ResultsOn average, the closest EPI program is 4 km away from the centre of any given neighbourhood (range 0.8-11 km), with variability across the city. Clustering is observed in some neighbourhoods, indicating better spatial accessibility, whereas other neighbourhoods face lower access. A full spatial regression model showed increasing levels of housing and dwelling marginalization, as well as material resource marginalization, to be associated with better access.ConclusionWe identified neighbourhoods that have poorer spatial accessibility to EPI services. Some neighbourhood-level marginalization indicators previously found to be associated with psychosis risk are also associated with better spatial accessibility. It is notable that EPI services in Toronto may be located where they are most needed the most. The study underscores the importance of geospatial analyses to identify and address geographic distance as a potential source of disparity in access.

期刊介绍: Established in 1956, The Canadian Journal of Psychiatry (The CJP) has been keeping psychiatrists up-to-date on the latest research for nearly 60 years. The CJP provides a forum for psychiatry and mental health professionals to share their findings with researchers and clinicians. The CJP includes peer-reviewed scientific articles analyzing ongoing developments in Canadian and international psychiatry.
