Healthcare expenditure on Indigenous and non-Indigenous Australians at high risk of cardiovascular disease

Background: In spite of bearing a heavier burden of death, disease and disability, there is mixed evidence as to whether Indigenous Australians utilise more or less healthcare services than other Australians given their elevated risk level. This study analyses the Medicare expenditure and its predictors in a cohort of Indigenous and non-Indigenous Australians at high risk of cardiovascular disease. Methods: The healthcare expenditure of participants of the Kanyini Guidelines Adherence with the Polypill (GAP) pragmatic randomised controlled trial was modelled using linear regression methods. 535 adult (48% Indigenous) participants at high risk of cardiovascular disease (CVD) were recruited through 33 primary healthcare services (including 12 Aboriginal Medical Services) across Australia. Results: There was no significant difference in the expenditure of Indigenous and non-Indigenous participants in non-remote areas following adjustment for individual characteristics. Indigenous individuals living in remote areas had lower MBS expenditure ($932 per year P< 0.001) than other individuals. MBS expenditure was found to increase with being aged over 65 years ($128, p=0.013), being female ($472, p=0.003), lower baseline reported quality of life ($102 per 0.1 decrement of utility p=0.004) and a history of diabetes ($324, p=0.001), gout ($631, p=0.022), chronic obstructive pulmonary disease ($469, p=0.019) and established CVD whether receiving guideline-recommended treatment prior to the trial ($452, p=0.005) or not ($483, p=0.04). When controlling for all other characteristics, morbidly obese patients had lower MBS expenditure than other individuals (-$887, p=0.002). Conclusion: The findings suggest that for the majority of participants, once individuals are engaged with a primary care provider, factors other than whether they are Indigenous determine the level of Medicare expenditure for each person.

Rationale and design of the Kanyini guidelines adherence with the polypill (Kanyini-GAP) study: a randomised controlled trial of a polypill-based strategy amongst Indigenous and non Indigenous people at high cardiovascular risk

<p>Abstract</p> <p>Background</p> <p>The Kanyini Guidelines Adherence with the Polypill (Kanyini-GAP) Study aims to examine whether a polypill-based strategy (using a single capsule containing aspirin, a statin and two blood pressure-lowering agents) amongst Indigenous and non-Indigenous people at high risk of experiencing a cardiovascular event will improve adherence to guideline-indicated therapies, and lower blood pressure and cholesterol levels.</p> <p>Methods/Design</p> <p>The study is an open, randomised, controlled, multi-centre trial involving 1000 participants at high risk of cardiovascular events recruited from mainstream general practices and Aboriginal Medical Services, followed for an average of 18 months. The participants will be randomised to one of two versions of the polypill, the version chosen by the treating health professional according to clinical features of the patient, or to usual care. The primary study outcomes will be changes, from baseline measures, in serum cholesterol and systolic blood pressure and self-reported current use of aspirin, a statin and at least two blood pressure lowering agents. Secondary study outcomes include cardiovascular events, renal outcomes, self-reported barriers to indicated therapy, prescription of indicated therapy, occurrence of serious adverse events and changes in quality-of-life. The trial will be supplemented by formal economic and process evaluations.</p> <p>Discussion</p> <p>The Kanyini-GAP trial will provide new evidence as to whether or not a polypill-based strategy improves adherence to effective cardiovascular medications amongst individuals in whom these treatments are indicated.</p> <p>Trial Registration</p> <p>This trial is registered with the Australian New Zealand Clinical Trial Registry ACTRN126080005833347.</p

SARS-CoV-2 Omicron is an immune escape variant with an altered cell entry pathway

Vaccines based on the spike protein of SARS-CoV-2 are a cornerstone of the public health response to COVID-19. The emergence of hypermutated, increasingly transmissible variants of concern (VOCs) threaten this strategy. Omicron (B.1.1.529), the fifth VOC to be described, harbours multiple amino acid mutations in spike, half of which lie within the receptor-binding domain. Here we demonstrate substantial evasion of neutralization by Omicron BA.1 and BA.2 variants in vitro using sera from individuals vaccinated with ChAdOx1, BNT162b2 and mRNA-1273. These data were mirrored by a substantial reduction in real-world vaccine effectiveness that was partially restored by booster vaccination. The Omicron variants BA.1 and BA.2 did not induce cell syncytia in vitro and favoured a TMPRSS2-independent endosomal entry pathway, these phenotypes mapping to distinct regions of the spike protein. Impaired cell fusion was determined by the receptor-binding domain, while endosomal entry mapped to the S2 domain. Such marked changes in antigenicity and replicative biology may underlie the rapid global spread and altered pathogenicity of the Omicron variant

Management of Hospital Formularies in Ontario: Challenges within a Local Health Integration Network

ABSTRACTBackground: Expenditures on drugs dispensed and administered to patients in Canadian hospitals have been estimated at $2.4 billion per year. Pharmacy and therapeutics (P&amp;T) committees play a key role in the evaluation and management of drug therapies in this setting. Hospitals differ with respect to the composition of these committees, their members’ expertise, and the processes used for making formulary decisions.Objectives: To examine the current processes for formulary drug review from the perspective of P&amp;T committees and their individual members, and to examine the needs and preferences of these stakeholders related to evidence review and potential collaborative drug review processes within a large Local Health Integration Network (LHIN) in Ontario.Methods: Twenty-three sites within 10 hospital corporations in LHIN 4 (Hamilton Niagara Haldimand Brant) were recruited. A 2-part questionnaire was developed and pretested for clarity and comprehensiveness. The institution profile section of the questionnaire was to be completed by pharmacy directors and the P&amp;T section by committee members.Results: Ten pharmacy directors and 28 committee members representing 10 P&amp;T committees responded. A mean of 6.4 new drug requests were reviewed annually by each P&amp;T committee. Across the LHIN, the workload associated with reviewing submissions for new drugs to be added to the formulary represented 0.84 full-time equivalent. The quality of clinical evidence in the drug submissions was rated more favourably than the quality of economic evidence; furthermore, the use of economic evidence was limited by a lack of health economics expertise within the committees. A centralized review process for the LHIN was perceived as beneficial to improve efficiency, the quality of review, and standardization, and also to reduce costs.Conclusions: Across the Hamilton Niagara Haldimand Brant LHIN, considerable time and resources are spent on the review of potential new drugs for addition to the hospitals’ formularies. A standardized formulary review process, with greater use of provincial and national drug reviews, would likely benefit all LHINs.RÉSUMÉContexte : Les dépenses pour les médicaments distribués et administers aux patients dans les hôpitaux canadiens ont été évaluées à 2,4 milliards de dollars par année. Les comités de pharmacologie et de thérapeutique jouent un rôle central dans l’analyse et la prise en charge des pharmacotherapies dans ce milieu. La composition de ces comités et l’expertise de leurs membres varient d’un hôpital à l’autre, tout comme les processus qui y sont employés pour prendre des décisions à propos de la liste des médicaments.Objectifs : Étudier les processus actuels d’ajout de médicaments à la liste locale du point de vue des comités de pharmacologie et de thérapeutique et de leurs membres. Examiner les besoins et préférences de ces parties prenantes quant à l’analyse des données probantes et aux potentiels processus collaboratifs d’évaluation des médicaments au sein d’un important réseau local d’intégration des services de santé (RLISS) ontarien.Méthodes : Vingt-trois établissements dans 10 organisations hospitalières du RLISS 4 (Hamilton Niagara Haldimand Brant) ont été retenus. On a élaboré un questionnaire de deux parties qui a été testé au préalable pour en vérifier la clarté et l’exhaustivité. La section sur le profil de l’établissement devait être remplie par les directeurs de pharmacie et celle sur la pharmacologie et la thérapeutique devait l’être par les membres des comités.Résultats : Dix directeurs de pharmacie et 28 membres représentant 10 comités de pharmacologie et de thérapeutique ont répondu. En moyenne, 6,4 nouvelles demandes d’ajout de médicament étaient analysées annuellement par chaque comité. Dans l’ensemble du RLISS, la charge de travail nécessaire à l’analyse des demandes d’ajout de nouveaux médicaments à la liste locale représentait 0,84 d’un poste équivalent temps plein. La qualité des données cliniques probantes dans les demandes d’ajout était considérée plus favorablement que celle des données économiques. De plus, comme les membres des comités ne possédaient pas l’expertise nécessaire en économie de la santé, l’utilisation des données probantes à ce sujet était limitée. Un processus centralisé d’analyse pour le RLISS était perçu comme avantageux pour améliorer l’efficience, la qualité de l’analyse et la normalization ainsi que pour réduire les coûts.Conclusions : Dans l’ensemble du RLISS de Hamilton Niagara Haldimand Brant, beaucoup de ressources et de temps sont accordés à évaluer l’ajout de médicaments à la liste locale. Tous les RLISS tireraient sûrement profit d’un processus normalisé d’ajout à la liste locale des médicaments ainsi que d’une meilleure utilisation des évaluations réalisées par les organismes provinciaux et national

Do campo à "Campanha": gênero, performance e narrativas orais na fronteira entre o Brasil e o Uruguai From countryside to "Campaign": gender, performance and oral narratives in Brazil and Uruguay border's

Neste artigo abordo questões referentes à configuração dos papéis de gênero entre contadoras e contadores de "causos" da região da fronteira entre Brasil e Uruguai, considerando também o papel da pesquisadora nesse contexto. Na pesquisa etnográfica realizada, as diferenças entre os gêneros foram gradualmente revelando sua importância para o estudo das histórias narradas e, consequentemente, para a compreensão da sociedade fronteiriça. Assim como na organização social local percebe-se uma clara divisão do trabalho, do tempo e dos espaços ocupados por homens e mulheres, também nas narrativas orais e nas suas performances essa divisão encontrará correspondência. Levando em conta esses aspectos, procuro demonstrar de que maneira, seja no conteúdo das narrativas, seja na forma de contá-las, essas diferenças vão sendo demarcadas.<br>This article focuses on questions concerning the configurations of the gender roles among the female and male storytellers at Brazil/Uruguay border, taking into consideration the role of the researcher in this context. The differences of gender were gradually revealing its importance in the study of the oral narratives and, consequently, in understanding the frontier society, in the context of the present ethnography. The sexual division of work, time and space present in the local social organization is expanded to the oral narratives as well as to their performances. I intend to explore how these aspects, on narrative contents and/or on the way they are told, are being constructed while these differences are being delimitated
