The primary objective of this study was to examine the impacts associated with implementation of overdose preventions sites (OPSs) in Victoria, Canada during a declared provincial public health overdose emergency. A rapid case study design was employed with three OPSs constituting the cases. Data were collected through semi-structured interviews with 15 staff, including experiential staff, and 12 service users. Theoretically, we were informed by the Consolidated Framework for Implementation Research. This framework, combined with a case study design, is well suited for generating insight into the impacts of an intervention. Zero deaths were identified as a key impact and indicator of success. The implementation of OPSs increased opportunities for early intervention in the event of an overdose, reducing trauma for staff and service users, and facilitated organizational transitions from provision of safer supplies to safer spaces. Providing a safer space meant drug use no longer needed to be concealed, with the effect of mitigating drug related stigma and facilitating a shift from shame and blame to increasing trust and development of relationships with increased opportunities to provide connections to other services. These impacts were achieved with few new resources highlighting the commitment of agencies and harm reduction workers, particularly those with lived experience, in achieving beneficial impacts. Although mitigating harms of overdose, OPSs do not address the root problem of an unsafe drug supply. OPSs are important life-saving interventions, but more is needed to address the current contamination of the illicit drug supply including provision of a safer supply.
Background People who use substances experience high levels of substance-related stigma, both within and outside of health care settings, which can prevent people from help-seeking and contribute further to health inequities. Recognizing and respecting how political, social, economic, and historical conditions influence health and health care, cultural safety, with origins in addressing Indigenous racism, is a potential strategy for mitigating stigma and marginalization in health care. Using a participatory research approach, we applied the concept of cultural safety to develop a model of safe primary care from the perspective of people who use substances. Methods People who use or used substances were involved in all phases of the research and led data collection. Study participants (n = 75) were 42.5 years old on average; half identified as female and one quarter as Indigenous. All were currently using or had previous experience with substances (alcohol and/or other drugs) and were recruited through two local peer-run support agencies. Concept mapping with hierarchical cluster analysis was used to develop the model of safe primary care, with data collected over three rounds of focus groups. Results Participants identified 73 unique statements to complete the focus prompt: “I would feel safe going to the doctor if …” The final model consisted of 8 clusters that cover a wide range of topics, from being treated with respect and not being red-flagged for substance use, to preserving confidentiality, advocacy for good care and systems change, and appropriate accommodations for anxiety and the effects of poverty and criminalization. Conclusions Developing a definition of safe care (from the patient perspective) is the necessary first step in creating space for positive interactions and, in turn, improve care processes. This model provides numerous concrete suggestions for providers, as well as serving as starting point for the development of interventions designed to foster system change.
BackgroundPrior animal model and human-based studies have linked selenium concentrations to decreased risk for depression; however, this work has not focused on household groundwater levels or specific depressive symptoms. The current study evaluated the link between groundwater selenium levels and depression. We also sought to determine if a functional polymorphism in the glutathione peroxidase 1 (GPX1) gene impacted this link.MethodsWe used a cross-sectional design to analyze data from 585 participants (183 men and 402 women) from Project FRONTIER, a study of rural health in West Texas. Residential selenium concentrations were estimated using Geospatial Information System (GIS) analyses. Linear regression models were created using Geriatric Depression Scale (GDS-30) total and subfactor scores as outcome variables and selenium concentrations as predictor variables. Analyses were re-run after stratification of the sample on GPX1 Pro198Leu genotype (rs1050454).ResultsSelenium levels were significantly and negatively related to all GDS and subfactor scores accounting for up to 17% of the variance beyond covariates. Selenium was most strongly protective against depression among homozygous carriers of the C allele at the Pro198Leu polymorphism of the GPX1 gene. Analyses also point towards a gene-environmental interaction between selenium exposure and GPX1 polymorphism.ConclusionOur results support the link between groundwater selenium levels and decreased depression symptoms. These findings also highlight the need to consider the genetics of the glutathione peroxidase system when examining this relationship, as variation in the GPX1 gene is related to depression risk and significantly influences the protective impact of selenium, which is indicative of a gene-environment interaction.
Background Europe and North America are in the grips of a devastating overdose crisis. People who use substances often feel unsafe to access healthcare due to fears of stigma, blame, judgement, poor treatment, or other repercussions. As a result, they often avoid, delay, or leave care, resulting in premature death and missed opportunities for care. Internationally, there have been concerted efforts to move towards patient-engaged research to enhance the quality of health care systems and services. In Canada, the Canadian Institutes of Health Research (CIHR) Strategy for Patient-Oriented Research (SPOR) initiative promotes engagement of patients as active partners in health care research. As part of a community based patient oriented research project, we critically analyze the SPOR framework to provide insights into what constitutes safer research with people who use(d) substances. Methods We undertook a two-stage process that began with a review of community based research principles and the SPOR framework. At the second stage, we undertook a qualitative descriptive study employing focus groups to generate description of the adequacy and appropriateness of the SPOR framework for guiding research with people who use(d) substances on four key dimensions (patient engagement, guiding principles, core areas of engagement and benefits). The data were analyzed using qualitative content analysis to identify key issues and insights. Results While the SPOR framework includes a range of patient roles, principles and areas for engagement, there are issues and gaps related to essential elements of safe patient-oriented research for people who use substances. These include an individualized focus on patients as partners, lack of recognition of community benefits, power imbalances and distrust due to systemic stigma, engagement as one way capacity building and learning, and lack of accountability for taking action on research findings. Conclusions Given the extent of stigma in health care and the ongoing illicit drug policy crisis, strategies for enhancing equitable Patient-Oriented Research (POR) include shifting language from patient partners to community researchers, recognizing power inequities and adding trust and equity as core POR principles including pay equity. Employing community based participatory research as a POR methodology allows the lead researchers to fully engage community throughout the research process, enhances community benefits and accountability for action.
