RESUMEN

Contribution Analysis (CA) is a promising theory-based evaluation approach for complex interventions, yet its application in health interventions remains largely unexplored. To bridge this gap, we conducted a scoping review to examine the extent of such applications and the methodologies, strengths, and limitations of this approach in health programming. Our comprehensive search strategy was developed and used in 15 databases to identify peer-reviewed articles from 1999 to 2023 that focused on using CA to evaluate health interventions. We then implemented rigorous double- and triple-screening processes for abstracts and full-text papers, respectively. Data were extracted and narratively summarized. Our review found seven relevant studies, which showed that CA has been employed in health promotion programs, health policies, and targeted health issues such as nutrition, cardiovascular disease, substance misuse, and suicide prevention. The studies identified strengths of using CA, including its flexible impact evaluation approach, capacity to inform decision-making, and potential to enhance understanding of health programs and policies. However, challenges such as how to determine suitable evidence levels and how to best manage resource intensity were also identified. The limited number of studies indicates that CA is still a novel approach, whereas the variation in the reporting of the studies suggests that this approach could benefit from more standardized methods and detailed stakeholder engagement strategies.

RESUMEN

Identifying the main threats to soil biodiversity is crucial as soils harbor ∼60% of global biodiversity. Many previous meta-analyses investigating the impact of different global changes (GCs) on biodiversity have omitted soil fauna or are limited by the GCs studied. We conducted a broad-scale meta-analysis focused on soil fauna communities, analyzing 3,161 effect sizes from 624 publications studying climate change, land-use intensification, pollution, nutrient enrichment, invasive species and habitat fragmentation. Land-use intensification resulted in large reductions in soil fauna communities, especially for the larger-bodied groups. Unexpectedly, pollution caused the largest negative impact on soil biodiversity - particularly worrying due to continually increasing levels of pollution and poor mechanistic understanding of impacts relative to other GCs. Not all GCs and stressors were detrimental; organic-based nutrient enrichment often resulted in positive responses. Including soil biodiversity in large-scale analyses is vital to fully understand the impact of GCs across the different realms.

RESUMEN

BACKGROUND: Situated within a larger project entitled "Exploring the Need for a Uniquely Different Approach in Northern Ontario: A Study of Socially Accountable Artificial Intelligence," this rapid review provides a broad look into how social accountability as an equity-oriented health policy strategy is guiding artificial intelligence (AI) across the Canadian health care landscape, particularly for marginalized regions and populations. This review synthesizes existing literature to answer the question: How is AI present and impacted by social accountability across the health care landscape in Canada? METHODOLOGY: A multidisciplinary expert panel with experience in diverse health care roles and computer sciences was assembled from multiple institutions in Northern Ontario to guide the study design and research team. A search strategy was developed that broadly reflected the concepts of social accountability, AI and health care in Canada. EMBASE and Medline databases were searched for articles, which were reviewed for inclusion by 2 independent reviewers. Search results, a description of the studies, and a thematic analysis of the included studies were reported as the primary outcome. PRINCIPAL FINDINGS: The search strategy yielded 679 articles of which 36 relevant studies were included. There were no studies identified that were guided by a comprehensive, equity-oriented social accountability strategy. Three major themes emerged from the thematic analysis: (1) designing equity into AI; (2) policies and regulations for AI; and (3) the inclusion of community voices in the implementation of AI in health care. Across the 3 main themes, equity, marginalized populations, and the need for community and partner engagement were frequently referenced, which are key concepts of a social accountability strategy. CONCLUSION: The findings suggest that unless there is a course correction, AI in the Canadian health care landscape will worsen the digital divide and health inequity. Social accountability as an equity-oriented strategy for AI could catalyze many of the changes required to prevent a worsening of the digital divide caused by the AI revolution in health care in Canada and should raise concerns for other global contexts.

RESUMEN

Fungi are among the most diverse and ecologically important kingdoms in life. However, the distributional ranges of fungi remain largely unknown as do the ecological mechanisms that shape their distributions1,2. To provide an integrated view of the spatial and seasonal dynamics of fungi, we implemented a globally distributed standardized aerial sampling of fungal spores3. The vast majority of operational taxonomic units were detected within only one climatic zone, and the spatiotemporal patterns of species richness and community composition were mostly explained by annual mean air temperature. Tropical regions hosted the highest fungal diversity except for lichenized, ericoid mycorrhizal and ectomycorrhizal fungi, which reached their peak diversity in temperate regions. The sensitivity in climatic responses was associated with phylogenetic relatedness, suggesting that large-scale distributions of some fungal groups are partially constrained by their ancestral niche. There was a strong phylogenetic signal in seasonal sensitivity, suggesting that some groups of fungi have retained their ancestral trait of sporulating for only a short period. Overall, our results show that the hyperdiverse kingdom of fungi follows globally highly predictable spatial and temporal dynamics, with seasonality in both species richness and community composition increasing with latitude. Our study reports patterns resembling those described for other major groups of organisms, thus making a major contribution to the long-standing debate on whether organisms with a microbial lifestyle follow the global biodiversity paradigms known for macroorganisms4,5.

RESUMEN

Introduction: Rural communities have poorer health compared to urban populations due partly to having lesser healthcare access. Rural placements during medical education can equip students with the knowledge and skills to work in rural communities, and, it is hoped, increase the supply of rural physicians. It is unclear how students gain knowledge of rural generalism during placements, and how this can be understood in terms of place-based and/or sociocultural educational theories. To gain insight into these questions we considered the experiences of pre-clerkship medical students who completed two mandatory four-week rural placements during their second year of medical school. Methods: Data was collected using semi-structured interviews or focus groups, followed by thematic analysis of the interview transcripts. Results: Rural placements allowed students to learn about rural generalism such as breadth of practice, and boundary issues. This occurred mainly by students interacting with rural physician faculty, with the effectiveness of precepting being key to students acquiring knowledge and skills and reporting a positive regard for the placement experience. Discussion: Our data show the central role of generalist physician preceptors in how and what students learn while participating in rural placements. Sociocultural learning theory best explains student learning, while place-based education theory helps inform the curriculum. Effective training and preparation of preceptors is likely key to positive student placement experiences.

Introduction: Les communautés rurales sont en moins bonne santé que les populations urbaines, en partie parce qu'elles ont moins accès aux soins de santé. Les stages de médecine en milieu rural peuvent permettre aux étudiants d'acquérir les connaissances et les compétences nécessaires pour travailler dans les communautés rurales et, on l'espère, augmenter le nombre de médecins y travaillent. On ne sait pas clairement comment les étudiants acquièrent des connaissances sur le généralisme rural au cours de leurs stages, et comment cela peut être compris en termes de théories éducatives socioculturelles et/ou basées sur le lieu de travail. Pour répondre à ces questions, nous avons étudié les expériences d'étudiants en médecine au pré-clinique qui ont effectué deux stages obligatoires de quatre semaines en milieu rural au cours de leur deuxième année d'études de médecine. Méthodes: Les données ont été recueillies au moyen d'entrevues semi-structurées ou de groupes de discussion, suivis d'une analyse thématique des transcriptions des entrevues. Résultats: Les stages en milieu rural ont permis aux étudiants de se familiariser avec le généralisme rural, notamment l'étendue de la pratique et les questions de limites. L'efficacité du préceptorat est essentielle pour que les étudiants acquièrent des connaissances et des compétences et qu'ils aient une expérience de stage positive. Discussion: Nos données témoignent du rôle central que jouent les médecins généralistes précepteurs quant au contenu et modes d'apprentissage des étudiants lorsqu'ils participent à des stages en milieu rural. La théorie de l'apprentissage socioculturel est celle qui explique le mieux l'apprentissage des étudiants, tandis que la théorie de la formation fondée sur le lieu contribue à orienter le programme d'études. Une formation et préparation efficace des précepteurs est probablement la clé d'une expérience de stage positive pour les étudiants.

RESUMEN

INTRODUCTION: The Northern Ontario School of Medicine University seeks to address rural physician shortages in Northern Ontario. One key strategy the school employs is the use of experiential learning placements embedded throughout its undergraduate curriculum. In second year, students embark on two 4-week placements in rural and remote communities. This study sought to explore the factors that contribute to a positive learning experience from the preceptor's perspective. METHODS: Semi-structured interviews were conducted with five community preceptors who have participated in these placements. Using the information from these interviews a survey was created and sent to another 15 preceptors. Data were analyzed using qualitative methods and frequencies. RESULTS: Three key themes were identified from both the interviews and survey data: the role of early rural and remote placements; the risks of these placements; and the need for a reciprocal relationship between institutions, preceptors, and students to create a positive learning environment. CONCLUSION: Preceptors value the opportunity to teach students, but the aims of these placements are not clear and preceptors and local hospitals need more workforce resources to make these experiences positive.

RESUMEN

Novel methods for sampling and characterizing biodiversity hold great promise for re-evaluating patterns of life across the planet. The sampling of airborne spores with a cyclone sampler, and the sequencing of their DNA, have been suggested as an efficient and well-calibrated tool for surveying fungal diversity across various environments. Here we present data originating from the Global Spore Sampling Project, comprising 2,768 samples collected during two years at 47 outdoor locations across the world. Each sample represents fungal DNA extracted from 24 m3 of air. We applied a conservative bioinformatics pipeline that filtered out sequences that did not show strong evidence of representing a fungal species. The pipeline yielded 27,954 species-level operational taxonomic units (OTUs). Each OTU is accompanied by a probabilistic taxonomic classification, validated through comparison with expert evaluations. To examine the potential of the data for ecological analyses, we partitioned the variation in species distributions into spatial and seasonal components, showing a strong effect of the annual mean temperature on community composition.

RESUMEN

Globally, lung cancer is the leading cause of cancer death. Previous trials demonstrated that low-dose computed tomography lung cancer screening of high-risk individuals can reduce lung cancer mortality by 20% or more. Lung cancer screening has been approved by major guidelines in the United States, and over 4,000 sites offer screening. Adoption of lung screening outside the United States has, until recently, been slow. Between June 2017 and May 2019, the Ontario Lung Cancer Screening Pilot successfully recruited 7,768 individuals at high risk identified by using the PLCOm2012noRace lung cancer risk prediction model. In total, 4,451 participants were successfully screened, retained and provided with high-quality follow-up, including appropriate treatment. In the Ontario Lung Cancer Screening Pilot, the lung cancer detection rate and the proportion of early-stage cancers were 2.4% and 79.2%, respectively; serious harms were infrequent; and sensitivity to detect lung cancers was 95.3% or more. With abnormal scans defined as ones leading to diagnostic investigation, specificity was 95.5% (positive predictive value, 35.1%), and adherence to annual recall and early surveillance scans and clinical investigations were high (>85%). The Ontario Lung Cancer Screening Pilot provides insights into how a risk-based organized lung screening program can be implemented in a large, diverse, populous geographic area within a universal healthcare system.

RESUMEN

How the multiple facets of soil fungal diversity vary worldwide remains virtually unknown, hindering the management of this essential species-rich group. By sequencing high-resolution DNA markers in over 4000 topsoil samples from natural and human-altered ecosystems across all continents, we illustrate the distributions and drivers of different levels of taxonomic and phylogenetic diversity of fungi and their ecological groups. We show the impact of precipitation and temperature interactions on local fungal species richness (alpha diversity) across different climates. Our findings reveal how temperature drives fungal compositional turnover (beta diversity) and phylogenetic diversity, linking them with regional species richness (gamma diversity). We integrate fungi into the principles of global biodiversity distribution and present detailed maps for biodiversity conservation and modeling of global ecological processes.

RESUMEN

PROBLEM ADDRESSED: Family physicians stand to benefit from assistance with the implementation of social accountability strategies. OBJECTIVE OF PROGRAM: To develop rapid evidence narratives for key social accountability topics that summarize and mobilize evidence for practical use in social accountability strategies linking front-line, "bottom-up" actions with complementary "top-down" standards from the SAFE (Social Accountability as the Framework for Engagement) for Health Institutions evaluation tool. PROGRAM DESCRIPTION: The SAFE for Health Institutions project aims to accelerate transformation toward greater social accountability in family medicine practices and in other settings where family physicians work. A social accountability evaluation tool was developed to help with this transformation and includes a framework of 253 comprehensive top-down standards. Key social accountability topics linked to these standards were identified for rapid reviews of the literature, conducted between June and November 2021, with evidence reported as narratives. These rapid evidence narratives provide practical, evidence-based context including suggestions on how to address each topic across the micro, meso, and macro levels of care, connecting bottom-up actions with corresponding considerations for top-down policies, processes, and structures. Summaries of the rapid evidence narratives are being developed as a series of articles for Canadian Family Physician, focusing on what family physicians can do in clinical practices, with interdisciplinary teams, and in other work settings to accelerate change toward adopting or advancing socially accountable strategies. CONCLUSION: Rapid evidence narratives that summarize and mobilize evidence on key social accountability topics further the understanding of social accountability in family medicine and in other settings where family physicians work. Mapping actions across the micro, meso, and macro levels of care is a practical way to link front-line, bottom-up actions with a top-down social accountability strategy.

RESUMEN

OBJECTIVES: Social accountability is an equity-oriented health policy strategy that requires institutions to focus on local population needs. This strategy is well established in health professional education, but there is limited understanding of its application in healthcare service delivery. Building on what is known in the education setting, this study aimed to explore the development of a framework of comprehensive, evidence-based social accountability standards for healthcare service delivery institutions. DESIGN: This qualitative, multipart, multimethods study consisted of a modified Delphi process guided by an evidence-based social accountability tool for health professional education and complementary methods including developmental evaluation and a review of select literature to capture emerging evidence and contextual relevance. SETTING: The study took place in Northern Ontario, Canada at a medical school and a tertiary, regional academic health sciences centre that are both grounded in social accountability. PARTICIPANTS: Eight expert participants from diverse, multidisciplinary backgrounds, including a patient advocate, were purposefully recruited from both institutions, enrolled and seven completed the study. MAIN OUTCOME: The resulting framework of social accountability standards is organised into 4 major sections that capture broad and critical concepts; 17 key component reflective questions that address key themes; 39 aspirations that describe objective standards and 197 indicators linked to specific expectations. RESULTS: Three modified Delphi rounds were completed producing a framework of consensus derived standards. Developmental evaluation helped identify facilitators, barriers and provided real-time feedback to the study's processes and content. The literature reviewed identified 10 new concepts and 43 amendments. CONCLUSION: This study highlights the development of a comprehensive, evidence-based framework of social accountability standards for healthcare service delivery institutions. Future studies will aim to evaluate the application of these standards to guide equity-oriented social accountability health policy strategies in healthcare service delivery.

RESUMEN

Globally, Indigenous populations have been impacted by colonization. Populations who have endured colonization are at higher risk of developing chronic diseases. Canada's Truth and Reconciliation Commission emphasizes reducing barriers to participation in physical activity and recommends the creation of culturally relevant and supportive policies and programing. Physical activity is a cornerstone in health promotion and public health to combat chronic diseases; however, in Canada, Indigenous developed physical activity programing is sparse, and those targeting women are non-existent in some regions. Makoyoh'sokoi (The Wolf Trail Program) is an 18-week long, holistic wellness program that was created by and for Indigenous women. Makoyoh'sokoi was developed by communities following extensive consultation and cultural oversight. Makoyoh'sokoi's core program consists of 12 weeks of weekly physical activity programing and health education, followed by another 6 weeks of weekly health education. Notably, communities have control over the program to modify based on individual needs and challenges. Programs commence and conclude with a ceremony with Elders giving a blessing and opening each other to connection. The goals of Makoyoh'sokoi are to empower women, improve health outcomes, and to implement a sustainable program by training a network of community members in their respective communities to facilitate delivery.

RESUMEN

Background: There is currently a maldistribution of physicians across Canada, with rural areas facing a greater physician shortage. The taskforce between the College of Family Physicians and the Society of Rural Physicians created a report, "The Rural Road Map for Action" (RRMA) to improve rural Canadians' health by training and retaining an increased number of rural family physicians. Using the RRMA as a framework, this paper aims to examine the extent to which medical schools in Canada are following the RRMA. Methods: Researchers used cross-sectional survey and collected data from 12 of 17 medical school undergraduate Deans from across Canada using both closed and open ended survey questions. Results were analyzed using quantitative (frequencies) and qualitative methods (content analysis). Results: Medical schools use different policies and procedures to recruit rural and Indigenous students. Although longitudinal integrated clerkships offer many benefits, few students have access to them. Leadership representation on decision-making education committees differed across medical schools pointing to a variation in the value of rural physicians' perspectives. Conclusion: This study illustrated that medical schools are making efforts that align with the RRMA. It is critical they continue to make strategic decisions embedded in educational policy and leadership to reinforce the importance of and influence of rural medical education to support workforce planning.

Contexte: À l'heure actuelle, la répartition des médecins sur le territoire canadien est inégale, les régions rurales étant confrontées à une plus forte pénurie de médecins. Le groupe de travail constitué par le Collège des médecins de famille du Canada (CMFC) et la Société de la médecine rurale du Canada (SMRC) a produit un rapport intitulé « Plan d'action pour la médecine rurale ¼ (PAMR) qui vise à améliorer la santé des Canadiens vivant en milieu rural par la formation et la rétention d'un nombre accru de médecins de famille en milieu rural. Cet article évalue dans quelle mesure les facultés de médecine du Canada suivent les recommandations du PAMR. Méthodes: Les chercheurs ont eu recours à une enquête transversale, comportant des questions fermées et ouvertes, pour recueillir des données auprès de 12 des 17 doyens aux études de premier cycle des facultés de médecine canadiennes. Les résultats ont été analysés à l'aide de méthodes quantitatives (calcul des fréquences) et qualitatives (analyse de contenu). Résultats: Les facultés de médecine appliquent des politiques et des procédures différentes pour recruter des étudiants d'origine rurale ou autochtone. Les externats longitudinaux intégrés offrent de nombreux avantages, mais peu d'étudiants y ont accès. La diversité au sein des comités pédagogiques décisionnels est si variable que l'on peut en déduire que le point de vue des médecins exerçant en milieu rural n'est pas toujours valorisé. Conclusion: Cette étude montre que les facultés de médecine déploient des initiatives qui sont conformes au PAMR. Il est essentiel que leurs décisions stratégiques demeurent ancrées dans un leadership et une politique éducative visant à renforcer et à mettre en valeur l'exposition des étudiants à la médecine rurale pour soutenir la planification des effectifs.

RESUMEN

INTRODUCTION: Low-dose computed tomography screening in high-risk individuals reduces lung cancer mortality. To inform the implementation of a provincial lung cancer screening program, Ontario Health undertook a Pilot study, which integrated smoking cessation (SC). METHODS: The impact of integrating SC into the Pilot was assessed by the following: rate of acceptance of a SC referral; proportion of individuals who were currently smoking cigarettes and attended a SC session; the quit rate at 1 year; change in the number of quit attempts; change in Heaviness of Smoking Index; and relapse rate in those who previously smoked. RESULTS: A total of 7768 individuals were recruited predominantly through primary care physician referral. Of these, 4463 were currently smoking and were risk assessed and referred to SC services, irrespective of screening eligibility: 3114 (69.8%) accepted referral to an in-hospital SC program, 431 (9.7%) to telephone quit lines, and 50 (1.1%) to other programs. In addition, 4.4% reported no intention to quit and 8.5% were not interested in participating in a SC program. Of the 3063 screen-eligible individuals who were smoking at baseline low-dose computed tomography scan, 2736 (89.3%) attended in-hospital SC counseling. The quit rate at 1 year was 15.5% (95% confidence interval: 13.4%-17.7%; range: 10.5%-20.0%). Improvements were also observed in Heaviness of Smoking Index (p < 0.0001), number of cigarettes smoked per day (p < 0.0001), time to first cigarette (p < 0.0001), and number of quit attempts (p < 0.001). Of those who reported having quit within the previous 6 months, 6.3% had resumed smoking at 1 year. Furthermore, 92.7% of the respondents reported satisfaction with the hospital-based SC program. CONCLUSIONS: On the basis of these observations, the Ontario Lung Screening Program continues to recruit through primary care providers, to assess risk for eligibility using trained navigators, and to use an opt-out approach to referral for cessation services. In addition, initial in-hospital SC support and intensive follow-on cessation interventions will be provided to the extent possible.

RESUMEN

BACKGROUND: The novel coronavirus, COVID-19, emerged in December 2019. Shortly after, vaccines against the virus were distributed in Canada for public use, but the remoteness of many northern Indigenous communities in Ontario posed a challenge for vaccine distribution and dissemination. The Ministry of Health partnered with the Northern Ontario School of Medicine University (NOSMU) and the air ambulance service, Ornge, to assist in delivering the vaccination doses to 31 fly-in communities in the Nishnawbe Aski Nation and Moosonee, all within Ontario. These deployments were considered "service-learning electives" for Undergraduate and Postgraduate medical learners from NOSMU who joined the operation in two-week deployments. NOSMU is renowned for its social accountability mandate and gives its medical learners opportunities to participate in service-learning to enhance their medical skills and cultural sensitivity. The purpose of this study is to examine the relationship between social accountability and medical learners' experiences during a service-learning elective in northern Indigenous communities in Ontario during the COVID-19 pandemic. METHODS: Data were collected through a planned post-placement activity completed by eighteen Undergraduate and Postgraduate medical learners, who participated in the vaccine deployment. The activity consisted of a 500-word reflective response passage. Thematic analysis was used to identify, analyze, and report the themes within the collected data. RESULTS: Two themes were identified by the authors, which formed a concise overview of the collected data: (1) confronting the realities of working in Indigenous communities; and (2) service-learning as a path to social accountability. CONCLUSIONS: These vaccine deployments were an opportunity for medical learners to engage in service-learning and engage with Indigenous communities in Northern Ontario. Service-learning is an exceptional method which provides an opportunity to expand knowledge on the social determinants of health, social justice, and social accountability. The medical learners in this study reiterated the idea that learning medicine through a service-learning model leads to a greater depth of knowledge on Indigenous health and culture, and enhances medical knowledge compared to classroom learning.

RESUMEN

INTRODUCTION: The COVID-19 pandemic had significant impacts on many aspects of health care and education, including the accreditation of medical education programmes. As a community of international educators, it is important that we study changes that resulted from the pandemic to help us understand educational processes more broadly. As COVID-19 unfolded in Canada, a revised format of undergraduate medical accreditation was implemented, including a shift to virtual site visits, a two-stage visit schedule, a focused approach to reviewing standards and the addition of a field secretary to the visit team. Our case study research aimed to evaluate the sociomaterial implications of these changes in format on the process of accreditation at two schools. METHODS: We interviewed key informants to understand the impacts, strengths and limitations of changes made to the accreditation format. We used an abductive approach to analyse transcripts and applied a sociomaterial lens in looking for interconnections between the material and social changes that were experienced within the accreditation system. RESULTS: Stakeholders within the accreditation system did not anticipate that changes to the accreditation format would have significant impacts on how accreditation functioned or on its overall outcomes. However, key informants described how the revised format of accreditation reconstructed how power was distributed and how knowledge was produced. The revised format contributed to changes in who held power within each of the programmes, within each of the visiting teams and between site members and visiting team members. As power shifted across stakeholders in response to material changes to the accreditation format, key informants described changes in how knowledge was produced. CONCLUSIONS: Our findings suggest that the most powerful knowledge about any given programme might best be obtained through individualised tools, technologies and voices that are most meaningful to the unique context of each programme. Deliberate attention to how knowledge and power are influenced by the interactions between material and social processes within accreditation may help educators and leaders see the effects of change.
