Towards precision cancer medicine for Aboriginal and Torres Strait Islander cancer health equity.

Delivering cancer control at scale for Aboriginal and Torres Strait Islander communities is a national priority that requires Aboriginal and Torres Strait Islander leadership and codesign, as well as significant involvement of the Aboriginal community-controlled health sector. The unique genomic variation observed among Aboriginal and Torres Strait Islander peoples may have implications for standard and precision medicine. Yet, Aboriginal and Torres Strait Islander peoples are absent from, or under-represented within, human reference genome resources, genomic studies, cancer studies, cancer cell lines, patient-derived xenografts and cancer clinical trials. Genomics-guided precision cancer medicine offers an opportunity to reduce cancer health disparities experienced by Aboriginal and Torres Strait Islander peoples through personalising prevention, diagnosis, treatment and long term management. Here, we describe what is required to ensure that Aboriginal and Torres Strait Islander peoples can receive the benefits of precision cancer medicine. Equity of access to care, an Aboriginal and Torres Strait Islander cancer workforce, and appropriate genome reference resources are important for safe and effective cancer medicine. Building Indigenous data sovereignty principles and Aboriginal and Torres Strait Islander governance into research is required to protect Aboriginal and Torres Strait Islander rights and collective interests. Aboriginal and Torres Strait Islander community engagement should be undertaken to develop an understanding of the unique cultural and ethical considerations for precision cancer research. Local and national genomic health research guidelines are needed to define a consensus best practice in genomics research with Aboriginal and Torres Strait Islander peoples.

"My feelings and my thoughts are my lived experience, not the numbers they show me on a piece of paper": Indigenous experiences of liver transplantation in British Columbia, Canada.

Indigenous Peoples in Canada face healthcare inequities impacting access to solid organ transplantation. The experiences of Indigenous patients during the liver transplant process, and how transplant professionals perceive challenges faced by Indigenous Peoples, has not been studied. Thirteen semi-structured qualitative interviews were conducted via telehealth with Indigenous liver transplant patients (n = 7) and transplant care providers (n = 6) across British Columbia, Canada between April 2021-May 2022. Themes were identified to inform clinical approaches and transplant care planning and validated by Indigenous health experts. Among patient participants: transplants occurred between 1992-2020; all were women; and the mean age at the time of interview was 60 years. Among transplant care provider participants: roles included nursing, social work, and surgery; 83% were women; and the median number of years in transplant care was ten. Three broad themes were identified: Indigenous strengths and resources, systemic and structural barriers, and inconsistent care and cultural safety across health professions impact Indigenous patient care during liver transplantation. This study contributes insights into systemic barriers and Indigenous resilience in the liver transplant journey. Dismantling structural barriers to early linkage to care is needed, and training for transplant clinicians on Indigenous histories, cultural protocols, and cultural safety is strongly recommended.

Alcohol screening in 22 Australian Aboriginal Community Controlled Health Organisations: Clinical context and who is screened.

INTRODUCTION: Alcohol screening among Indigenous Australians is important to identify individuals needing support to reduce their drinking. Understanding clinical contexts in which clients are screened, and which clients are more or less likely to be screened, could help identify areas of services and communities that might benefit from increased screening. METHODS: We analysed routinely collected data from 22 Aboriginal Community Controlled Health Organisations Australia-wide. Data collected between February 2016 and February 2021 were analysed using R, and aggregated to describe screening activity per client, within 2-monthly extraction periods. Descriptive analyses were performed to identify contexts in which clients received an Alcohol Use Disorders Identification Test consumption (AUDIT-C) screen. Multi-level logistic regression determined demographic factors associated with receiving an AUDIT-C screen. Three models are presented to examine if screening was predicted by: (i) age; (ii) age and gender; (iii) age, gender and service remoteness. RESULTS: We observed 83,931 occasions where AUDIT-C was performed at least once during a 2-monthly extraction period. Most common contexts were adult health check (55.0%), followed by pre-consult examination (18.4%) and standalone item (9.9%). For every 10 years' increase in client age, odds of being screened with AUDIT-C slightly decreased (odds ratio 0.98; 95% confidence interval [CI] 0.98, 0.99). Women were less likely to be screened with AUDIT-C (odds ratio 0.95; 95% CI 0.93, 0.96) than men. DISCUSSION AND CONCLUSIONS: This study identified areas where alcohol screening can be increased (e.g., among women). Increasing AUDIT-C screening across entire communities could help reduce or prevent alcohol-related harms. Future Indigenous-led research could help identify strategies to increase screening rates.

Resolutividade no Subsistema de Atenção à Saúde Indígena no Brasil: revisão de escopo / Resolubility in the Indigenous Health Care Subsystem in Brazil: scope review / Resolución en el Subsistema de Atención de la Salud Indígena en Brasil: revisión del alcance

RESUMO: A resolutividade relaciona-se à capacidade de solução dos problemas de saúde nos serviços. Em 1999, o Subsistema de Atenção à Saúde Indígena foi integrado ao Sistema Único de Saúde no Brasil, passando a seguir os seus princípios e diretrizes. Este estudo teve por objetivo identificar e mapear os desafios ou problemas relacionados às práticas em saúde para a resolutividade no Subsistema de Saúde Indígena após a integração. Trata-se de uma revisão de escopo que utilizou seis bases de dados nacionais e internacionais. Os estudos elegíveis tiveram como critério base o mnemônico PCC (P: população indígena; C: desafios ou problemas para a resolutividade; C: subsistema de saúde indígena brasileiro). Foram encontrados 1.748 estudos e selecionados 33, com predomínio de estudos qualitativos. Os desafios ou problemas sensíveis para o processo da resolutividade foram encontrados nos aspectos que tangem à educação em saúde, à interculturalidade, ao acesso universal e aos recursos em gestão. O saber tradicional é pouco valorizado pelo sistema de saúde. A deficiência de recursos humanos e materiais, a falta de efetiva educação permanente e de capacitações para trabalhar no contexto intercultural produzem barreiras de acesso e comprometem a resolutividade nos serviços, aumentando assim as iniquidades em saúde.

ABSTRACT: Resolubility relates to the ability to solve health problems in services. In 1999, the Indigenous Health Care Subsystem was integrated into the Brazilian Unified Health System, following its principles and guidelines. The objective of this study was to identify and map the challenges or problems related to health practices for solving in the Indigenous Health Subsystem after integration. This is a scope review that used six national and international databases. Eligible studies were based on mnemonic PCC (P: indigenous population; C: challenges or problems for resolution; C: Brazilian indigenous health subsystem). A total of 1,748 studies were found and 33 were selected, with predominance of qualitative studies. The challenges or problems that are sensitive to the resolution process were found in the aspects that are related to health education, interculturality, universal access and management resources. Traditional knowledge is underrated by the health system. The deficiency of human and material resources, the lack of effective permanent education and capacitations to work in the intercultural context, produce barriers to access and compromise the resolubility in services, thus increasing the inequities in health.

RESUMEN: La resolución se refiere a la capacidad de resolver problemas de salud en los servicios. En 1999, el Subsistema de Atención de Salud Indígena se integró en el Sistema Único de Salud de Brasil, siguiendo sus principios y directrices. El objetivo de este estudio fue identificar y mapear los desafíos o problemas relacionados con las prácticas de salud para resolver en el Subsistema de Salud Indígena después de la integración. Esta es una revisión de alcance que utilizó seis bases de datos nacionales e internacionales. Los estudios elegibles se basaron en PCC mnemónicos (P: población indígena; C: desafíos o problemas para la resolución; C: subsistema de salud indígena brasileño). Se encontraron 1.748 estudios y se seleccionaron 33, con predominio de estudios cualitativos. Los desafíos o problemas que son sensibles al proceso de resolución se encontraron en los aspectos que están relacionados con la educación en salud, la interculturalidad, el acceso universal y los recursos de gestión. El conocimiento tradicional es subestimado por el sistema de salud. La deficiencia de recursos humanos y materiales, la falta de educación permanente efectiva y de capacitaciones para trabajar en el contexto intercultural, producen barreras para acceder y comprometer la solubilidad en los servicios, aumentando así las desigualdades en salud.

Active screening for tuberculosis in high-incidence Inuit communities in Canada: a cost-effectiveness analysis.

BACKGROUND: Active screening for tuberculosis (TB) involves systematic detection of previously undiagnosed TB disease or latent TB infection (LTBI). It may be an important step toward elimination of TB among Inuit in Canada. We aimed to evaluate the cost-effectiveness of community-wide active screening for TB infection and disease in 2 Inuit communities in Nunavik. METHODS: We incorporated screening data from the 2 communities into a decision analysis model. We predicted TB-related health outcomes over a 20-year time frame, beginning in 2019. We assessed the cost-effectiveness of active screening in the presence of varying outbreak frequency and intensity. We also considered scenarios involving variation in timing, impact and uptake of screening programs. RESULTS: Given a single large outbreak in 2019, we estimated that 1 round of active screening reduced TB disease by 13% (95% uncertainty range -3% to 27%) and was cost saving compared with no screening, over 20 years. In the presence of simulated large outbreaks every 3 years thereafter, a single round of active screening was cost saving, as was biennial active screening. Compared with a single round, we also determined that biennial active screening reduced TB disease by 59% (95% uncertainty range 52% to 63%) and was estimated to cost Can$6430 (95% uncertainty range -$29 131 to $13 658 in 2019 Can$) per additional active TB case prevented. With smaller outbreaks or improved rates of treatment initiation and completion for people with LTBI, we determined that biennial active screening remained reasonably cost-effective compared with no active screening. INTERPRETATION: Active screening is a potentially cost-saving approach to reducing disease burden in Inuit communities that have frequent TB outbreaks.

A casemix study of patients seen within an urban Aboriginal Health Service dermatology clinic over a five-year period.

This is the largest study of Aboriginal and Torres Strait Islander dermatologic presentations to an urban specialist clinic within a community-controlled health organisation. It adds to our understanding of Aboriginal and Torres Strait Islander dermatoepidemiology. Patient files were reviewed over the five-year audit period, with age, gender, Indigenous status, diagnosis, disease category, 'new' or 'review consultation' and 'did not attend' (DNA) data recorded. Our study shows that eczema and benign, pre-malignant or malignant neoplasms are the most common presentations for urban Aboriginal and Torres Strait Islander patients. Lupus erythematosus and cutaneous infections were less prominent in comparison to data from rural and remote populations. Overall, a broad casemix of dermatologic presentations was observed. Similar to other studies, adult male patients were under-represented. Most skin malignancies were diagnosed in this cohort; this, therefore, identifies a possible target for public health intervention. A high ratio of new to review patients is consistent with the clinic offering a consultation model of care facilitated by primary health-care providers' support within Aboriginal Community-Controlled Health Service. DNA rates in this study were lower than hospital outpatient rates in a comparative study and may be attributed to specialist dermatology care being offered in a more culturally sensitive environment. The dermatology clinic at the Victorian Aboriginal Health Services (VAHS) provides a good breadth of specialist dermatology care. The community health-care model could be replicated in centres elsewhere, including interstate, to help overcome barriers to specialist dermatology care experienced by Aboriginal and Torres Strait Islander populations. Additionally, this model improves trainee exposure and understanding of Aboriginal and Torres Strait Islander health.

Using community-led development to build health communication about rheumatic heart disease in Aboriginal children: a developmental evaluation.

OBJECTIVE: A high prevalence of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) among Aboriginal children in northern Australia is coupled with low understanding among families. This has negative impacts on children's health, limits opportunities for prevention and suggests that better health communication is needed. METHODS: During an RHD echocardiography screening project, Aboriginal teachers in a remote community school created lessons to teach children about RHD in their home languages, drawing on principles of community-led development. Access to community-level RHD data, previously unknown to teachers and families, was a catalyst for this innovative work. Careful, iterative discussions among speakers of four Aboriginal languages ensured a culturally coherent narrative and accompanying teaching resources. RESULTS: The evaluation demonstrated the importance of collective work, local Indigenous Knowledge and metaphors. As a result of the lessons, some children showed new responses and attitudes to skin infections and their RHD treatment. Language teachers used natural social networks to disseminate new information. A community interagency collaboration working to prevent RHD commenced. Conclusions and implications for public health: Action to address high rates of RHD must include effective health communication strategies that value Indigenous Knowledge, language and culture, collaborative leadership and respect for Indigenous data sovereignty.

Using Pharmaceutical Benefit Scheme data to understand the use of smoking cessation medicines by Aboriginal and Torres Strait Islander smokers.

OBJECTIVE: To examine the supply of smoking cessation medicines to Aboriginal and Torres Strait Islander smokers compared to non-Indigenous smokers across Australia. METHODS: We analysed the total number of smoking cessation prescriptions dispensed over three years through the Pharmaceutical Benefits Scheme (PBS) compared to those supplied nationally through the Closing the Gap (CTG) measure and also in the Northern Territory through the Remote Area Aboriginal Health Service (RAAHS) program. RESULTS: Aboriginal and Torres Strait Islander smokers were supplied with fewer smoking cessation medicines per smoker under the CTG measure compared to non-Indigenous smokers under general PBS benefits. Supply of medicines though the RAAHS program complicated the use of CTG data where higher proportions of Aboriginal and Torres Strait Islander people live in remote areas and use of the CTG measure is lower. CONCLUSIONS: Fewer smoking cessation medicines are being prescribed and then dispensed to Aboriginal and Torres Strait Islander smokers than to non-Indigenous smokers. Implications for public health: CTG and RAAHS data may be useful to monitor and evaluate the effectiveness of interventions to improve the use of smoking cessation medicines by Aboriginal and Torres Strait Islander smokers. However, there are limitations and current obstacles to accessing RAAHS data would need to be removed.

Atrial Fibrillation in Indigenous Australians: A Multisite Screening Study Using a Single-Lead ECG Device in Aboriginal Primary Health Settings.

BACKGROUND: Circulatory diseases continue to be the greatest cause of mortality for Australian Aboriginal and Torres Strait Islander people, and a major cause of persistently lower life expectancy compared with non-Aboriginal Australians. The limited information that exists on atrial fibrillation (AF) prevalence in Aboriginal and Torres Strait Islander communities is mostly based on hospital admission data. This shows AF as principal or additional admission diagnosis was 1.4 times higher compared to non-Aboriginal Australians, a higher incidence of AF across the adult life span after age 20 years and a significantly higher prevalence among younger patients. Our study estimates the first national community prevalence and age distribution of AF (including paroxysmal) in Australian Aboriginal people. A handheld single-lead electrocardiograph (ECG) device (iECG), known to be acceptable in this population, was used to record participant ECGs. METHODS: This co-designed, descriptive cross-sectional study was conducted in partnership with 16 Aboriginal Community Controlled Health organisations at their facilities and/or with their services delivered elsewhere. The study was also conducted at one state community event. Three (3) Australian jurisdictions were involved: New South Wales, Western Australia and the Northern Territory. Study sites were located in remote, regional and urban areas. Opportunistic recruitment occurred between June 2016 and December 2017. People <45 years of age were excluded. RESULTS: Thirty (30) of 619 Aboriginal people received a 'Possible AF' and 81 an 'Unclassified' result from a hand-held smartphone ECG device. A final diagnosis of AF was made in 29 participants (4.7%; 95%CI 3.0-6.4%), 25 with known AF (five paroxysmal), and four with previously unknown AF. Three (3) of the four with unknown AF were aged between 55-64 years, consistent with a younger age of AF onset in Aboriginal people. Estimated AF prevalence increased with age and was higher in those aged >55 years than the general population (7.2% compared with 5.4%). Slightly more men than women were diagnosed with AF. CONCLUSIONS: This study is a significant contribution to the evidence which supports screening for AF in Aboriginal and Torres Strait Islander people commencing at a younger age than as recommended in the Australian guidelines (>65 years). We recommend the age of 55 years. Consideration should be given to the inclusion of AF screening in the Australian Government Department of Health annual 'Aboriginal and Torres Strait Islander Health Assessment'. CLINICAL TRIAL REGISTRATION: ACTRN12616000459426.

US Rural Surgeons Leading During COVID-19: Where Are They Now?

Rural surgeons from disparate areas of the United States report on the effects of the COVID-19 pandemic in their communities as the virus has spread across the country. The pandemic has brought significant changes to the professional, economic, and social lives of the individual surgeons and their communities.

The experiences of Indigenous people with cancer in Saskatchewan: a patient-oriented qualitative study using a sharing circle.

BACKGROUND: Although disparities in cancer rates, later diagnoses and lower survival rates between Indigenous and non-Indigenous people have been documented, little is known about how Indigenous patients with cancer encounter the health care system. We explored perceptions and experiences of Indigenous patients with cancer and their families to understand better how 2 key concepts - trust and world view - influence cancer care decisions. METHODS: In this patient-oriented study that included participation of 2 patient partners, qualitative data were collected from Indigenous patients with cancer and their families using an Indigenous method of sharing circles. The sharing circle occurred at a culturally appropriate place, Wanuskewin Heritage Park, Saskatoon, on Sept. 22, 2017. The first patient partner started the sharing circle by sharing their cancer journey, thus engaging the Indigenous methodology of storytelling. This patient partner was involved in selecting the data collection method and recruiting participants through snowballing and social media. Trust and world view were employed as meta themes to guide our examination of the data. In keeping with Indigenous methodology, interview transcripts were analyzed using narrative analysis. The themes were reviewed and verified by a second Indigenous patient partner. RESULTS: There were 14 participants in the sharing circle. The 2 meta themes, trust and world view, comprised 8 subthemes. The meta theme trust included mistrust with diagnosis and Western treatment after cancer therapy, protection of Indigenous medicine and physician expertise with treatment recommendations. The world view meta theme included the following subthemes: best of both worlds, spiritual beliefs, required to be strong for family and importance of knowing Indigenous survivors. INTERPRETATION: This study displayed complex relations between trust and world view in the cancer journeys of Indigenous patients and their families. These findings may assist health care providers in gaining a better understanding of how trust and world view affect the decision-making of Indigenous patients regarding cancer care.

Improving Aboriginal Maternal Health by Strengthening Connection to Culture, Family and Community.

(1) Background: To explore the function of smoking in Aboriginal women's lives from a trauma-informed, women-centred approach in order to inform the design of a culturally meaningful smoking cessation program for women living in the Pilbara, Western Australia; (2) Methods: Qualitative and Community Based Participatory Action Research (CBPAR) was used to discover what Aboriginal women know about smoking, the specific contextual issues that influence their smoking, and what community supports are available to help them quit smoking. Inductive analysis was used to determine key themes; (3) Results: 25 Aboriginal women (smokers, non-smokers, and ex-smokers) participated in focus groups or individual interviews. Women smoked to deal with stress, trauma and for maintaining social connections. Women who stopped smoking did so on their own when the reason was important enough or when they saw alternative ways of living. Creating safe places to bring women together to yarn about women's business and link with health services was identified as critical to support women to stop smoking. Conclusions: Strategies to address smoking need to bring community, culture and health together in a meaningful way for women and their families; build on existing community strengths; and educate communities about the effects of smoking, and health professionals about how to support women to stop smoking.

Improving systems of care during and after a pregnancy complicated by hyperglycaemia: A protocol for a complex health systems intervention.

BACKGROUND: Many women with hyperglycaemia in pregnancy do not receive care during and after pregnancy according to standards recommended in international guidelines. The burden of hyperglycaemia in pregnancy falls disproportionately upon Indigenous peoples worldwide, including Aboriginal and Torres Strait Islander women in Australia. The remote and regional Australian context poses additional barriers to delivering healthcare, including high staff turnover and a socially disadvantaged population with a high prevalence of diabetes. METHODS: A complex health systems intervention to improve care for women during and after a pregnancy complicated by hyperglycaemia will be implemented in remote and regional Australia (the Northern Territory and Far North Queensland). The Theoretical Domains Framework was used during formative work with stakeholders to identify intervention components: (1) increasing workforce capacity, skills and knowledge and improving health literacy of health professionals and women; (2) improving access to healthcare through culturally and clinically appropriate pathways; (3) improving information management and communication; (4) enhancing policies and guidelines; (5) embedding use of a clinical register as a quality improvement tool. The intervention will be evaluated utilising the RE-AIM framework at two timepoints: firstly, a qualitative interim evaluation involving interviews with stakeholders (health professionals, champions and project implementers); and subsequently a mixed-methods final evaluation of outcomes and processes: interviews with stakeholders; survey of health professionals; an audit of electronic health records and clinical register; and a review of operational documents. Outcome measures include changes between pre- and post-intervention in: proportion of high risk women receiving recommended glucose screening in early pregnancy; diabetes-related birth outcomes; proportion of women receiving recommended postpartum care including glucose testing; health practitioner confidence in providing care, knowledge and use of relevant guidelines and referral pathways, and perception of care coordination and communication systems; changes to health systems including referral pathways and clinical guidelines. DISCUSSION: This study will provide insights into the impact of health systems changes in improving care for women with hyperglycaemia during and after pregnancy in a challenging setting. It will also provide detailed information on process measures in the implementation of such health system changes.

Salud intercultural y el modelo de salud propio indígena / Intercultural health and the indigenous health model

RESUMEN La población indígena tiene condiciones de vida inferiores al resto, reflejadas en mayor morbilidad y mortalidad a pesar de la cobertura del Sistema de Salud. Por ello, es importante conocer las causas de estas diferencias. Para esto, se hace uso de la interculturalidad como puente entre la cultura occidental y la cultura indígena. En este encuentro de saberes se identifica el modelo de salud indígena como respuesta cultural a la necesidad de mantener la salud y tratar la enfermedad, un modelo organizado jerárquicamente en el que la salud del individuo depende además de sus hábitos, de la armonía con la naturaleza, el espíritu, los dioses y su comunidad. Este modelo había sido menospreciado hasta hace poco tiempo por la comunidad científica; pero, gracias a los estudios en interculturalidad, se sabe que la salud también debe ser intercultural y que las políticas públicas deben incluirla para poder obtener los resultados esperados en la comunidad objetivo. Para hacer realidad estas políticas públicas debe haber voluntad y agenda política, una adecuada estructura en los servicios de salud y formación de los profesionales de la salud en interculturalidad desde sus estudios técnicos, tecnológicos, profesionales y de posgrado. Esas políticas públicas deben contener: capacitación, empleo de la lengua indígena local, alimentación y equipamiento con elementos tradicionales, diálogo respetuoso con los médicos tradicionales, atención humanizada, entre otros. Así se brinda una atención en salud de calidad que respeta las diferencias culturales de toda la población.(AU)

ABSTRACT The indigenous population has lower living conditions reflected in higher morbidity and mortality despite the coverage of the Health System, so it is important to know the causes of these differences. For this, Interculturality is used as a bridge between western culture and indigenous culture. In this meeting of knowledge, the indigenous health model is identified as a cultural response to the need to maintain health and treat disease, a hierarchically organized model in which the health of the individual also depends on their habits, on harmony with nature, the spirit, the gods and their community. Until recently, this model had been undervalued by the scientific community, but thanks to studies in Interculturality, it is known that health must also be intercultural and that public policies must include it in order to obtain the expected results in the target community. To make these public policies a reality, there must be a will and a political agenda, an adequate structure in the health services and training of health professionals in interculturality from their technical, technological, professional and postgraduate studies. These public policies must contain training, use of the local indigenous language, food and equipment with traditional elements, respectful dialogue with traditional doctors, humanized care, among others. This provides quality health care that is respectful of cultural differences to the entire population.(AU)

Alerta epidemiológica: COVID-19 en pueblos indígenas en las América - 15 de julio de 2020 / Epidemiological alert: COVID-19 in indigenous peoples in the Americas - July 15, 2020

Ante el incremento de casos y defunciones por COVID-19 en comunidades indígenas en las Américas, la Organización Panamericana de la Salud / Organización Mundial de la Salud (OPS/OMS) insta a los Estados Miembros a redoblar esfuerzos para prevenir el avance de la infección en dichas comunidades, así como también para asegurar el acceso a los servicios de atención de salud y fortalecer el manejo adecuado de casos con enfoque intercultural. Al mismo tiempo, la OPS/OMS urge a implementar medidas preventivas para reducir la mortalidad asociada a la COVID-19 en todos los niveles del sistema de salud.

A "one stop liver shop" approach improves the cascade-of-care for Aboriginal and Torres Strait Islander Australians living with chronic hepatitis B in the Northern Territory of Australia: results of a novel care delivery model.

BACKGROUND: Aboriginal and Torres Strait Islander Australians are disproportionately affected by Chronic Hepatitis B (CHB) with a prevalence of 6.08% in the Northern Territory (NT) and liver cancer rates 6 times higher than non-Indigenous Australians. Without appropriate care, overall 25% of those living with CHB will die from either liver failure or liver cancer, outcomes that can be minimised with regular follow up, antiviral treatment and hepatocellular carcinoma (HCC) screening. This care including antiviral treatment is publicly funded in the Australian setting however the care cascade still shows inequities in access to treatment for Aboriginal Australians. We describe the impact of a mobile care delivery model, "One Stop Liver Shop", on the cascade of care for people living with CHB in a remote Australian setting. METHODS: A retrospective analysis was performed for CHB care received between 2013 and 2018 in one very remote Northern Territory community, where the "One Stop Liver Shop" was iteratively developed with the community. Patients with positive Hepatitis B virus surface antigen (HBsAg) were identified through electronic medical records. Proportions of patients who are up-to-date with monitoring investigations and HCC screening were evaluated and compared to national guidelines and targets. RESULTS: Eighty-three HBsAg positive patients were evaluated. Eighty-eight percent were engaged in care, 16% of whom were receiving antiviral treatment. Liver function tests (LFT) were up to date in 71% of patients in 2013 and 88% in 2018. Viral load (VL) monitoring was up to date for 61 (73%) of patients. There were 44 patients in whom HCC screening was indicated. Of these, 38 (86.4%) were up to date with 6 monthly alpha-fetoprotein (AFP), 35 (79.5%) were up to date with 6 monthly liver ultrasound scan (USS), and 34 (77.3%) were up-to-date for both. CONCLUSIONS: A "One Stop Liver Shop" developed with and including Aboriginal Health Practitioners bridges gaps in the availability of services to those living with CHB in a very remote community and improves the cascade of care.

Primary Prevention of Cardiovascular Disease in Minority Indigenous Populations: A Systematic Review.

INTRODUCTION: Cardiovascular disease (CVD) is the commonest cause of death across the globe; incidence and prevalence rates are increasing. Together, CVD and diabetes mellitus are responsible for a quarter of the health gap observed between Aboriginal Australians and Torres Strait Islanders, and non-Indigenous Australians. Numerous programs have been proposed and implemented to Close the Gap; ideally, these should be evidence-based. OBJECTIVE: The aim of this review is to evaluate primary prevention measures and programs that aim to reduce CVD risk in minority Indigenous populations around the world. METHODS: A search of PubMed, the Cochrane Library and the Elsevier Scopus Database was initially conducted using the terms "cardiovascular disease", "population groups", "primary prevention", "health services, indigenous", "indigenous health", "risk assessment" and "risk management". Results were then assessed per inclusion/exclusion criteria. A second reviewer independently evaluated the publications and review process to ensure agreement. RESULTS: The initial search produced 37 publications; 19 met the inclusion criteria and were incorporated into a comparative table. Most were descriptive, mixed-methods, audit or intervention studies. Heterogeneity of study design prevented statistical analysis. CONCLUSION: Addressing CVD risk in minority Indigenous populations is a multifactorial challenge; there is substantial room for improvement in routine risk assessment and management. Holistic approaches need to embrace local cultural perceptions of health and wellbeing. Validated risk reduction tools, individualised management plans, polypills and computer based decision support tools are promising to improve outcomes for those at risk.

Condiciones en la frontera sur entre Colombia y Venezuela ante la pandemia de COVID-19 / Underlying conditions on the southern border between Colombia and Venezuela to face the COVID-19 pandemic

RESUMEN Objetivos Dimensionar la migración humana en la frontera sur entre Colombia y Venezuela (Departamento de Guainía), y caracterizar las condiciones sociales, de acceso y de atención en salud frente a la pandemia de COVID-19. Métodos Estudio mixto, epidemiológico y etnográfico. Se calcularon: tasa de migrantes venezolanos (según Migración Colombia al 31 de diciembre de 2019), acceso efectivo a atención médica y dotación en puestos de salud (según datos recolectados entre junio de 2017 y julio de 2019, en todos los puestos de salud de Guainía, mediante entrevistas semiestructuradas, observación participante y el uso de Google Earth™ y Wikiloc™). Los tiempos medianos se calcularon y graficaron en Stata™. Se describieron dinámicas culturales y de atención en salud a partir del trabajo de campo y de una permanente revisión documental. Resultados Guainía ocupa el puesto 23 en número total de venezolanos, pero es el cuarto departamento en densidad de venezolanos (14,4%). En ausencia del centro de salud de San José, en el río Guainía los tiempos medianos hasta la institución de referencia real son de 8,7 horas en invierno y 12,3 en verano y los casos complejos requieren remisión aérea. En el río Inírida, sin el centro de Chorro Bocón, los tiempos reales son de 11,9 horas en invierno y 16,1 en verano. Solo el 57% de los puestos de salud tenía insumos para manejar infección respiratoria aguda. Conclusiones Ante la llegada de COVID-19 a territorios sur-fronterizos, es necesario fortalecer inmediatamente servicios médicos y de salud pública para evitar elevadas tasas de letalidad.(AU)

ABSTRACT Objectives To size human migration on the southern border between Colombia and Venezuela (Guainía department), and characterize the social, access and health care conditions relevant to the COVID-19 pandemic. Methods Mixed epidemiological and ethnographic study. Rate of Venezuelan migrants was calculated according to Migration Colombia data until December 31st, 2019, also effective access to medical care, and provision of health posts were calculated, with information from each Guainía health post collected from June 2017 to June 2019, through semi-structured interviews, participant observations, Google Earth™ and Wikiloc™. Stata™ was used to calculate and graph median times of effective access. Cultural dynamics and health care conditions were described by the field work information and a permanent documentary review. Results Guainía is the 23rd department, according to the total number of Venezuelans, but the fourth in Venezuelans density (14,4%). In the Guainía river, the median times to the real reference health institution were 8,7 hours in winter and 12,3 in summer, and complex cases require air referrals. In the Inírida river, the median times to the real reference health institution were 11,9 hours in winter and 16,1 in summer. Only 57% of the health posts had supplies for acute respiratory infections. Conclusions Facing COVID-19 in south border territories, it is necessary to immediately strengthen medical and public health services to avoid high fatality rates.(AU)

Cardiovascular disease risk assessment for Aboriginal and Torres Strait Islander adults aged under 35 years: a consensus statement.

Cardiovascular disease (CVD) is a leading cause of preventable morbidity and mortality in Aboriginal and Torres Strait Islander peoples. This statement from the Australian Chronic Disease Prevention Alliance, the Royal Australian College of General Practitioners, the National Aboriginal Community Controlled Health Organisation and the Editorial Committee for Remote Primary Health Care Manuals communicates the latest consensus advice of guideline developers, aligning recommendations on the age to commence Aboriginal and Torres Strait Islander CVD risk assessment across three guidelines. MAIN RECOMMENDATIONS: In Aboriginal and Torres Strait Islander peoples without existing CVD: CVD risk factor screening should commence from the age of 18 years at the latest, including for blood glucose level or glycated haemoglobin, estimated glomerular filtration rate, serum lipids, urine albumin to creatinine ratio, and other risk factors such as blood pressure, history of familial hypercholesterolaemia, and smoking status. Individuals aged 18-29 years with the following clinical conditions are automatically conferred high CVD risk: ▶type 2 diabetes and microalbuminuria; ▶moderate to severe chronic kidney disease; ▶systolic blood pressure ≥ 180 mmHg or diastolic blood pressure ≥ 110 mmHg; ▶familial hypercholesterolaemia; or ▶serum total cholesterol > 7.5 mmol/L. Assessment using the National Vascular Disease Prevention Alliance absolute CVD risk algorithm should commence from the age of 30 years at the latest - consider upward adjustment of calculated CVD risk score, accounting for local guideline use, risk factor and CVD epidemiology, and clinical discretion. Assessment should occur as part of an annual health check or opportunistically. Subsequent review should be conducted according to level of risk. CHANGES IN MANAGEMENT AS A RESULT OF THIS STATEMENT: From age 18 years (at the latest), Aboriginal and Torres Strait Islander adults should undergo CVD risk factor screening, and from age 30 years (at the latest), they should undergo absolute CVD risk assessment using the NVDPA risk algorithm.
