RESUMO

INTRODUCTION: Evidence on the cost-effectiveness of comprehensive post-stroke programs is limited. We assessed the cost-effectiveness of an individualised management program (IMP) for stroke or transient ischaemic attack (TIA). METHODS: A cost-utility analysis alongside a randomised controlled trial with a 24-month follow-up, from both societal and health system perspectives, was conducted. Adults with stroke/TIA discharged from hospitals were randomised by primary care practice to receive either usual care (UC) or an IMP in addition to UC (intervention). An IMP included stroke-specific nurse-led education and a specialist review of care plans at baseline, 3 months, and 12 months, and telephone reviews by nurses at 6 months and 18 months. Costs were expressed in 2021 Australian dollars (AUD). Costs and quality-adjusted life years (QALYs) beyond 12 months were discounted by 5%. The probability of cost-effectiveness of the intervention was determined by quantifying 10,000 bootstrapped iterations of incremental costs and QALYs below the threshold of AUD 50,000/QALY. RESULTS: Among the 502 participants (65% male, median age 69 years), 251 (50%) were in the intervention group. From a health system perspective, the incremental cost per QALY gained was AUD 53,175 in the intervention compared to the UC group, and the intervention was cost-effective in 46.7% of iterations. From a societal perspective, the intervention was dominant in 52.7% of iterations, with mean per-person costs of AUD 49,045 and 1.352 QALYs compared to mean per-person costs of AUD 51,394 and 1.324 QALYs in the UC group. The probability of the cost-effectiveness of the intervention, from a societal perspective, was 60.5%. CONCLUSIONS: Care for people with stroke/TIA using an IMP was cost-effective from a societal perspective over 24 months. Economic evaluations of prevention programs need sufficient time horizons and consideration of costs beyond direct healthcare utilisation to demonstrate their value to society.

RESUMO

INTRODUCTION: Little is known about the cost-effectiveness of government policies that support primary care physicians to provide comprehensive chronic disease management (CDM). This paper aimed to estimate the potential cost-effectiveness of CDM policies over a lifetime for long-time survivors of stroke. METHODS: A Markov model, using three health states (stable, hospitalised, dead), was developed to simulate the costs and benefits of CDM policies over 30 years (with 1-year cycles). Transition probabilities and costs from a health system perspective were obtained from the linkage of data between the Australian Stroke Clinical Registry (cohort n = 12,368, 42% female, median age 70 years, 45% had CDM claims) and government-held hospital, Medicare, and pharmaceutical claims datasets. Quality-adjusted life years (QALYs) were obtained from a comparable cohort (n = 512, 34% female, median age 69.6 years, 52% had CDM claims) linked with Medicare claims and death data. A 3% discount rate was applied to costs in Australian dollars (AUD, 2016) and QALYs beyond 12 months. Probabilistic sensitivity analyses were used to understand uncertainty. RESULTS: Per-person average total lifetime costs were AUD 142,939 and 8.97 QALYs for those with a claim, and AUD 103,889 and 8.98 QALYs for those without a claim. This indicates that these CDM policies were costlier without improving QALYs. The probability of cost-effectiveness of CDM policies was 26.1%, at a willingness-to-pay threshold of AUD 50,000/QALY. CONCLUSION: CDM policies, designed to encourage comprehensive care, are unlikely to be cost-effective for stroke compared to care without CDM. Further research to understand how to deliver such care cost-effectively is needed.

RESUMO

OBJECTIVE: To determine the prevalence and associations of general practice registrars' performing absolute cardio-vascular risk (ACVR) assessment (ACVRa). DESIGN: A cross-sectional study employing data (2017-2018) from the Registrar Clinical Encounters in Training project, an ongoing inception cohort study of Australian GP registrars. The outcome measure was whether an ACVRa was performed. Analyses employed univariable and multivariable regression. Analysis was conducted for all patient problems/diagnoses, then for an 'at-risk' population (specific problems/diagnoses for which ACVRa is indicated). SETTING: Three GP regional training organisations (RTOs) across three Australian states. PARTICIPANTS: GP registrars training within participating RTOs. RESULTS: 1003 registrars (response rate 96.8%) recorded details of 69 105 problems either with Aboriginal and/or Torres Strait patients aged 35 years and older or with non-Indigenous patients aged 45 years and older. Of these problems/diagnoses, 1721 (2.5% (95% CI 2.4% to 2.6%)) involved an ACVRa. An ACVRa was 'plausibly indicated' in 10 384 problems/diagnoses. Of these, 1228 (11.8% (95% CI 11.2% to 12.4%)) involved ACVRa. For 'all problems/diagnoses', on multivariable analysis female gender was associated with reduced odds of ACVRa (OR 0.61 (95% CI 0.54 to 0.68)). There was some evidence for Aboriginal and/or Torres Strait Islander people being more likely to receive ACVRa (OR 1.40 (95% CI 0.94 to 2.08), p=0.10). There were associations with variables related to continuity of care, with reduced odds of ACVRa: if the patient was new to the registrar (OR 0.65 (95% CI 0.57 to 0.75)), new to the practice (OR 0.24 (95% CI 0.15 to 0.38)) or the problem was new (OR 0.68 (95% CI 0.59 to 0.78)); and increased odds if personal follow-up was organised (OR 1.43 (95% CI 1.24 to 1.66)). For 'ACVRa indicated' problems/diagnoses, findings were similar to those for 'all problems/diagnoses'. Association with Aboriginal and/or Torres Strait Islander status, however, was significant at p<0.05 (OR 1.60 (95% CI 1.04 to 2.46)) and association with female gender was attenuated (OR 0.88 (95% CI 0.77 to 1.01)). CONCLUSION: Continuity of care is associated with registrars assessing ACVR, reinforcing the importance of care continuity in general practice. Registrars' assessment of an individual patient's ACVR is targeted to patients with individual risk factors, but this may entail ACVRa underutilisation in female patients and younger age groups.

RESUMO

OBJECTIVE: To determine the cost-effectiveness and cost-utility of a quadpill containing irbesartan 37.5 mg, amlodipine 1.25 mg, indapamide 0.625 mg and bisoprolol 2.5 mg in comparison with irbesartan 150 mg for people with hypertension who are either untreated or receiving monotherapy. METHODS: We conducted a within-trial and modelled economic evaluation of the Quadruple UltrA-low-dose tReaTment for hypErTension trial. The analysis was preplanned, and medications and health service use captured during the trial. The main outcomes were incremental cost-effectiveness ratios (ICERs) for cost per mm Hg systolic blood pressure (BP) reduction at 3 months, and modelled cost per quality-adjusted life year (QALY) over a lifetime. RESULTS: The within-trial analysis showed no clear difference in cost per mm Hg BP lowering between randomised treatments at 3 months ($A10 (95% uncertainty interval (UI) $A -18 to $A37) per mm Hg per person) for quadpill versus monotherapy. The modelled cost-utility over a lifetime projected a mean incremental cost of $A265 (95% UI $A166 to $A357) and a mean 0.02 QALYs gained (95% UI 0.01 to 0.03) per person with quadpill therapy compared with monotherapy. Quadpill therapy was cost-effective in the base case (ICER of $A14 006 per QALY), and the result was sensitive to the quadpill cost in one-way sensitivity analysis. CONCLUSIONS: Quadpill in comparison with monotherapy is comparably cost-effective for short-term BP lowering. In the long-term, quadpill therapy is likely to be cost-effective.

RESUMO

RATIONALE: Theoretically, most strokes could be prevented through the management of modifiable risk factors. The Stroke Riskometer™ mobile phone application (hereon "The App") uses an individual's data to provide personalized information and advice to reduce their risk of stroke. AIMS: To determine the effect of The App on a combined cardiovascular risk score (Life's Simple 7®, LS7) of modifiable risk factors at 6 months post-randomization. METHODS AND DESIGN: PERKS-International is a Phase III, multicentre, prospective, pragmatic, open-label, single-blinded endpoint, two-arm randomized controlled trial (RCT). Inclusion criteria are as follows: age ⩾ 35 and ⩽75 years; ⩾2 LS7 risk factors; smartphone ownership; no history of stroke/myocardial infarction/cognitive impairment/terminal illness. The intervention group (IG) will be provided with The App, and the usual care group (UCG) is provided with generic online information about risk factors, but not be informed about The App. Face-to-face assessments will be conducted at baseline and 6 months, and online at 3 and 12 months. The RCT includes a process and economic evaluation. STUDY OUTCOMES AND SAMPLE SIZE: The primary outcome is a difference in the mean change in LS7 (seven individual items: blood pressure, cholesterol, glucose, body mass index (BMI), smoking, physical activity, and diet) from baseline to 6 months post-randomization with intention-to-treat analysis. Secondary outcomes include: change in individual LS7 items, quality of life; stroke awareness, adverse events; health service use; and costs. Based on pilot data, 790 participants (395 IG, 395 UCG) will be required to provide 80% power (two-sided α = 0.05) to detect a mean difference in the LS7 of ⩾0.40 (SD 1.61) in IG compared to 0.01 (SD 1.44) in the UCG at 6 months post-randomization. DISCUSSION: Stroke is largely preventable. This study will provide evidence of the effectiveness of a mobile app to reduce stroke risk. TRIAL REGISTRATION: ACTRN12621000211864.

RESUMO

The Northern Humboldt Current System sustains one of the most productive fisheries in the world. However, climate change is anticipated to negatively affect fish production in this region over the next few decades, and detailed analyses for many fishery resources are unavailable. We implemented a trait-based Climate Vulnerability Assessment based on expert elicitation to estimate the relative vulnerability of 28 fishery resources (benthic, demersal, and pelagic) to the impacts of climate change by 2055; ten exposure factors (e.g., temperature, salinity, pH, chlorophyll) and 13 sensitivity attributes (biological and population-level traits) were used. Nearly 36% of the species assessed had "high" or "very high" vulnerability. Benthic species were ranked the most vulnerable (gastropod and bivalve species). The pelagic group was the second most vulnerable; the Pacific chub mackerel and the yellowfin tuna were amongst the most vulnerable pelagic species. The demersal group had the relatively lowest vulnerability. This study allowed identification of vulnerable fishery resources, research and monitoring priorities, and identification of the key exposure factors and sensitivity attributes which are driving that vulnerability. Our findings can help fishery managers incorporate climate change into harvest level and allocation decisions, and assist stakeholders plan for and adapt to a changing future.

RESUMO

AIMS: The aim of this study was to assess the impact and cost-effectiveness of offering population genomic screening to all young adults in Australia to detect heterozygous familial hypercholesterolaemia (FH). METHODS AND RESULTS: We designed a decision analytic Markov model to compare the current standard of care for heterozygous FH diagnosis in Australia (opportunistic cholesterol screening and genetic cascade testing) with the alternate strategy of population genomic screening of adults aged 18-40 years to detect pathogenic variants in the LDLR/APOB/PCSK9 genes. We used a validated cost-adaptation method to adapt findings to eight high-income countries. The model captured coronary heart disease (CHD) morbidity/mortality over a lifetime horizon, from healthcare and societal perspectives. Risk of CHD, treatment effects, prevalence, and healthcare costs were estimated from published studies. Outcomes included quality-adjusted life years (QALYs), costs and incremental cost-effectiveness ratio (ICER), discounted 5% annually. Sensitivity analyses were undertaken to explore the impact of key input parameters on the robustness of the model. Over the lifetime of the population (4 167 768 men; 4 129 961 women), the model estimated a gain of 33 488years of life lived and 51 790 QALYs due to CHD prevention. Population genomic screening for FH would be cost-effective from a healthcare perspective if the per-test cost was ≤AU$250, yielding an ICER of

RESUMO

Climate change is impacting the function and distribution of habitats used by marine, coastal, and diadromous species. These impacts often exacerbate the anthropogenic stressors that habitats face, particularly in the coastal environment. We conducted a climate vulnerability assessment of 52 marine, estuarine, and riverine habitats in the Northeast U.S. to develop an ecosystem-scale understanding of the impact of climate change on these habitats. The trait-based assessment considers the overall vulnerability of a habitat to climate change to be a function of two main components, sensitivity and exposure, and relies on a process of expert elicitation. The climate vulnerability ranks ranged from low to very high, with living habitats identified as the most vulnerable. Over half of the habitats examined in this study are expected to be impacted negatively by climate change, while four habitats are expected to have positive effects. Coastal habitats were also identified as highly vulnerable, in part due to the influence of non-climate anthropogenic stressors. The results of this assessment provide regional managers and scientists with a tool to inform habitat conservation, restoration, and research priorities, fisheries and protected species management, and coastal and ocean planning.

RESUMO

BACKGROUND: The mid-life emergence of higher levels of total cholesterol (TC) for women than for men has been observed in different Western and Asian populations. The aim of this study was to investigate whether there is evidence of this in Vietnam and, if so, whether it can be explained by ageing, by body size and fatness, or by socio-demographic characteristics and behavioural factors. METHODS: Participants (n = 14706, 50.9% females) aged 25-64 years were selected by multi-stage stratified cluster sampling from eight provinces each representing one of the eight geographical regions of Vietnam. Measurements were made using the World Health Organization STEPS protocols. Linear regression was used to assess the independent contributions of potential explanatory factors to mean levels of TC. Data were analysed using complex survey methods. RESULTS: Men and women had similar mean levels of body mass index (BMI), and men had modestly higher mean levels of waist circumference (WC), in each 5-year age category. The mean TC of women increased more or less continuously across the age range but with a step-up at age 50 years to reach higher concentrations on average than those of their male counterparts. The estimated step-up was not eliminated by adjustment for anthropometric indices including BMI or WC, or by adjustment for socio-demographic characteristics or behavioural factors. The estimated step-up was least for women with the greatest weight. CONCLUSION: There is a marked step-up in TC at age 50 years for Vietnamese women that cannot be explained by their age, or by their body fatness or its distribution, or by their socio-demographic characteristics or behavioural factors, and which results in greater mean levels of TC for middle-aged women than for their male counterparts in Vietnam.

RESUMO

Subarachnoid hemorrhage (SAH) is a common form of hemorrhagic stroke associated with high rates of mortality and severe disability. SAH patients often develop severe neurological deficits days after ictus, events attributed to a phenomenon referred to as delayed cerebral ischemia (DCI). Recent studies indicate that SAH-induced DCI results from a multitude of cerebral circulatory disturbances including cerebral autoregulation malfunction. Cerebral autoregulation incorporates the influence of blood pressure (BP) on arterial diameter in the homeostatic regulation of cerebral blood flow (CBF), which is necessary for maintaining constant brain perfusion during physiological swings in systemic BP. In this study, we quantitatively examined the impact of SAH on cerebral autoregulation using a mouse endovascular perforation model and a newly developed approach combining absolute and relative CBF measurements. This method enables a direct quantitative comparison of cerebral autoregulation between individual animals (e.g., SAH vs. control or sham-operated mice), which cannot be done solely using relative CBF changes by laser Doppler flowmetry. Here, absolute CBF was measured via injection of fluorescent microspheres at a baseline BP. In separate groups of animals, in vivo laser Doppler flowmetry was used to measure relative CBF changes over a range of BP using phlebotomy and the pressor phenylephrine to lower and raise BP, respectively. Absolute CBF measurements from microspheres were then used to calibrate laser Doppler measurements to calculate the relationship between CBF and BP, i.e., "cerebral autoregulation curves." Un-operated and sham-operated groups exhibited similar cerebral autoregulatory curves, showing comparable levels of relatively constant CBF over a range of BP from ~80 mmHg to ~130 mmHg. In contrast, SAH animals exhibited a narrower autoregulatory range of BP, which was primarily due to a decrease in the upper limit of BP whereby cerebral autoregulation was maintained. Importantly, SAH animals also exhibited a marked decrease in CBF throughout the entire range of BP. In sum, this study provides evidence of the dramatic reduction in cortical CBF and the diminished range of autoregulation after SAH. Furthermore, this novel methodology should pave the way for future studies examining pathological mechanisms and/or therapeutic strategies targeting impaired cerebral autoregulation, a pathology common to many cardiovascular and cerebrovascular disorders.

RESUMO

BACKGROUND: Absolute cardiovascular disease (aCVD) risk assessment is recommended in CVD prevention guidelines. Yet, General Practitioners (GPs) often focus on single risk factors, including blood pressure (BP). Pathology services may be suitable to undertake high-quality automated unobserved BP (AOBP) measurement and aCVD risk assessment. This study explored GP attitudes towards AOBP measurement via pathology services and the role of BP in aCVD risk management. METHODS: A brief survey was completed, after which a focus group (n = 8 GPs) and interviews (n = 10 GPs) explored attitudes to AOBP and aCVD risk via pathology services with an example pathology report discussed. Verbatim transcripts were thematically coded. RESULTS: GPs predominantly used doctor-measured BP despite low levels of confidence. High BP measured by AOBP reported with aCVD risk via pathology services, would prompt a follow-up response. However, GPs focused on BP management. GPs were concerned about AOBP equivalency to routine BP measurements. After protocol explanation, GPs reported AOBP could value-add to care delivery. CONCLUSION: GPs lacked familiarity of AOBP and maintained a focus on BP management in the context of absolute CVD risk. Targeted education on AOBP and BP management as part of absolute CVD risk is needed to support guideline-directed care in practice.

RESUMO

BACKGROUND: Health and medical research funding agencies are increasingly interested in measuring the impact of funded research. We present a research impact case study for the first four years of an Australian National Health and Medical Research Council funded Centre of Research Excellence in Cardiovascular Outcomes Improvement (2016-2020). The primary aim of this paper was to explore the application of a research impact matrix to assess the impact of cardiovascular outcomes improvement research. METHODS: We applied a research impact matrix developed from a systematic review of existing methodological frameworks used to measure research impact. This impact matrix was used as a bespoke tool to identify and understand various research impacts over different time frames. Data sources included a review of existing internal documentation from the research centre and publicly available information sources, informal iterative discussions with 10 centre investigators, and confirmation of information from centre grant and scholarship recipients. RESULTS: By July 2019, the impact on the short-term research domain category included over 41 direct publications, which were cited over 87 times (median journal impact factor of 2.84). There were over 61 conference presentations, seven PhD candidacies, five new academic collaborations, and six new database linkages conducted. The impact on the mid-term research domain category involved contributions towards the development of a national cardiac registry, cardiovascular guidelines, application for a Medicare Benefits Schedule reimbursement item number, introduction of patient-reported outcome measures into several databases, and the establishment of nine new industry collaborations. Evidence of long-term impacts were described as the development and use of contemporary management for aortic stenosis, a cardiovascular risk prediction model and prevention targets in several data registries, and the establishment of cost-effectiveness for stenting compared to surgery. CONCLUSIONS: We considered the research impact matrix a feasible tool to identify evidence of academic and policy impact in the short- to midterm; however, we experienced challenges in capturing long-term impacts. Cost containment and broader economic impacts represented another difficult area of impact to measure.

RESUMO

Newly expressed proteins in genetically engineered crops are evaluated for potential cross reactivity to known allergens as part of their safety assessment. This assessment uses a weight-of-evidence approach. Two key components of this allergenicity assessment include any history of safe human exposure to the protein and/or the source organism from which it was originally derived, and bioinformatic analysis identifying amino acid sequence relatedness to known allergens. Phosphomannose-isomerase (PMI) has been expressed in commercialized genetically engineered (GE) crops as a selectable marker since 2010 with no known reports of allergy, which supports a history of safe exposure, and GE events expressing the PMI protein have been approved globally based on expert safety analysis. Bioinformatic analyses identified an eight-amino-acid contiguous match between PMI and a frog parvalbumin allergen (CAC83047.1). While short amino acid matches have been shown to be a poor predictor of allergen cross reactivity, most regulatory bodies require such matches be assessed in support of the allergenicity risk assessment. Here, this match is shown to be of negligible risk of conferring cross reactivity with known allergens.

RESUMO

OBJECTIVES: To assess the efficacy of a pro-active, absolute cardiovascular risk-guided approach to opportunistically modifying cardiovascular risk factors in patients without coronary ischaemia attending a chest pain clinic. DESIGN: Prospective, randomised, open label, blinded endpoint study. SETTING: The rapid access chest pain clinic of Royal Hobart Hospital, a tertiary hospital. PARTICIPANTS: Patients who presented to the chest pain clinic between 1 July 2014 and 31 December 2017 who had intermediate to high absolute cardiovascular risk scores (5-year risk ≥ 8%). Patients with known cardiac disease or from groups with clinically determined high risk of cardiovascular disease were excluded. MAIN OUTCOME MEASURES: The primary endpoint was change in 5-year absolute risk score (Australian absolute risk calculator) at follow-up (at least 12 months after baseline assessment). Secondary endpoints were changes in lipid profile, blood pressure, smoking status, and body mass index, and major adverse cardiovascular events. RESULTS: The mean change in risk at follow-up was +0.4 percentage points (95% CI, -0.8 to 1.5 percentage points) for the 98 control group patients and -2.4 percentage points (95% CI, -1.5 to -3.4 percentage points) for the 91 intervention group patients; the between-group difference in change was 2.7 percentage points (95% CI, 1.2-4.1 percentage points). Mean changes in lipid profile, systolic blood pressure, and smoking status were larger for the intervention group, but not statistically different from those for the control group. CONCLUSIONS: An absolute cardiovascular risk-guided, pro-active risk factor management strategy employed opportunistically in a chest pain clinic significantly improved 5-year absolute cardiovascular risk scores. TRIAL REGISTRATION: Australia New Zealand Clinical Trial Registry, ACTRN12617000615381 (retrospective).

RESUMO

INTRODUCTION: Physical rehabilitation for total hip replacement patients following hospital discharge is beneficial; however, accessing rehabilitation is often challenging. Telerehabilitation helps negate access issues and is efficacious in total knee and hip replacement patients. This study aims to compare the cost-effectiveness of a telerehabilitation programme delivered remotely into patients' homes versus traditional care for total hip replacement patients following hospital discharge. METHODS: A cost-effectiveness (cost-utility) analysis was conducted from the perspective of a health service alongside a two-arm randomised controlled trial comparing telerehabilitation (n=35) with in-person care (n=35) following hospital discharge after total hip replacement. The primary analysis used an Incremental Cost-Effectiveness Ratio to compare the cost per Quality Adjusted Life Year (QALY) accrued in the telerehabilitation group versus in-person control using costs and effects data from the randomised trial. A secondary analysis was conducted whereby the time accrued by patients attending rehabilitation sessions (including travel time) was considered the "cost" (i.e. a time burden), rather than cost from the health service perspective. RESULTS: Estimated mean differences in healthcare costs and QALYs gained were detected but were not significant. The estimated mean (95%CI) difference in cost of telerehabilitation versus in-person was -$28.90 (-$96.37 to $40.45), favouring the telerehabilitation group. The estimated mean (95%CI) difference in QALYs gained from telerehabilitation versus in-person was -0.0025 (-0.0227 to 0.0217). The estimated mean (95%CI) difference in time burden favoured less time burden for the telerehabilitation group (-4.21 (-4.69 to -3.74) hours). DISCUSSION: Telerehabilitation in the total hip replacement population incurred similar costs and yielded similar effects to traditional in-person care. Telerehabilitation significantly reduced the time burden for patients and carers. These findings are valuable for healthcare providers seeking to implement accessible patient-centred rehabilitation services.

RESUMO

BACKGROUND: Guidelines for cardiovascular disease (CVD) prevention recommend assessment of absolute CVD risk to guide clinical management. Despite this, use among general practitioners (GPs) remains limited. OBJECTIVE: Pathology services may provide an appropriate setting to assess and report absolute CVD risk in patients attending for cholesterol measurement. This study aimed to explore GPs perceptions of such a service. METHODS: A focus group and semi-structured interviews were conducted with GPs (n = 18) in Tasmania, Australia, to identify perceptions of assessment and reporting of absolute CVD risk via pathology services. An example pathology report including absolute CVD risk was provided and discussed. Audio-recordings were transcribed and thematically coded by two researchers. RESULTS: Almost all GPs identified that absolute CVD risk assessed and reported via pathology services could address deficits in practice. First, by reducing the number of appointments required to collect risk factors. Second, by providing a systematic (rather than opportunistic) approach for assessment of absolute CVD risk. Third, by reducing misclassification of patient CVD risk caused by overreliance on clinical intuition. All GPs reported they would order absolute CVD risk when issuing a cholesterol referral if such a service was offered. GPs recommended improving the service by providing information on methods used to measure risk factors on the pathology report. CONCLUSIONS: Absolute CVD risk assessed and reported via pathology services may address challenges of screening CVD risk experienced by GPs in practice and encourage dedicated follow-up care for CVD prevention.

RESUMO

BACKGROUND: Blood collection and blood pressure (BP) measurements are routinely performed during the same consultation to assess absolute cardiovascular disease (CVD) risk. This study aimed to determine the effect of blood collection on BP and subsequent calculation of the absolute CVD risk. METHODS: Forty-five participants aged 58 ± 9 years (53% male) had systolic BP (SBP) measured using clinical guideline methods (clinic SBP). Then, on a separate visit, BP was measured immediately before, during, and after blood collection. Absolute CVD risk scores were calculated (Framingham equation) using SBP from each measurement condition and compared. RESULTS: The prevalence of low (<10%), moderate (10-15%), and high (≥15%) absolute CVD risks among the participants was 67%, 22%, and 11%, respectively, using clinic SBP. SBP values before and during blood collection were significantly higher compared to values after blood collection (130 ± 18 and 132 ± 19 vs. 126 ± 18 mm Hg; p = 0.010 and p = 0.003, respectively). However, there were no significant differences between clinic SBP (128 ± 18 mm Hg) and blood collection SBP (p = 0.99) or the absolute CVD risk scores (7.3 ± 6.5; 7.6 ± 5.9; 7.7 ± 6.1; and 7.1 ± 5.7%, respectively; p = 0.995 for all). The mean intraclass correlation (95% CI) indicated good agreement between absolute CVD risk scores calculated with clinic SBP and each blood collection SBP (0.86 [95% CI 0.74-0.92], 0.85 [95% CI 0.71-0.91], and 0.87 [95% CI 0.76-0.93], respectively; p < 0.001, for all). CONCLUSION: Absolute CVD risk calculation is not affected by use of SBP measurements recorded at the time of blood collection. Therefore, it is acceptable to collect blood and measure BP during the same consultation for absolute CVD risk assessment.

RESUMO

BACKGROUND: Cardiovascular disease is the leading cause of death in Australia. Investment in research solutions has been demonstrated to yield health and a 9.8-fold return economic benefit. The sector, however, is severely challenged with success rates of traditional peer-reviewed funding in decline. Here, we aimed to understand the perceived challenges faced by the cardiovascular workforce in Australia prior to the COVID-19 pandemic. METHODS: We used an online survey distributed across Australian cardiovascular societies/councils, universities and research institutes over a period of 6 months during 2019, with 548 completed responses. Inclusion criteria included being an Australian resident or an Australian citizen who lived overseas, and a current or past student or employee in the field of cardiovascular research. RESULTS: The mean age of respondents was 42±13 years, 47% were male, 85% had a full-time position, and 40% were a group leader or laboratory head. Twenty-three per cent (23%) had permanent employment, and 82% of full-time workers regularly worked >40 hours/week. Sixty-eight per cent (68%) said they had previously considered leaving the cardiovascular research sector. If their position could not be funded in the next few years, a staggering 91% of respondents would leave the sector. Compared to PhD- and age-matched men, women were less likely to be a laboratory head and to feel they had a long-term career path as a cardiovascular researcher, while more women were unsure about future employment and had considered leaving the sector (all p<0.05). Greater job security (76%) and government and philanthropic investment in cardiovascular research (72%) were highlighted by responders as the main changes to current practices that would encourage them to stay. CONCLUSION: Strategic solutions, such as diversification of career pathways and funding sources, and moving from a competitive to a collaborative culture, need to be a priority to decrease reliance on government funding and allow cardiovascular researchers to thrive.

RESUMO

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has introduced a major disruption to the delivery of routine health care across the world. This provides challenges for the use of secondary prevention measures in patients with established atherosclerotic cardiovascular disease (CVD). The aim of this Position Statement is to review the implications for effective delivery of secondary prevention strategies during the COVID-19 pandemic. CHALLENGES: The COVID-19 pandemic has introduced limitations for many patients to access standard health services such as visits to health care professionals, medications, imaging and blood tests as well as attendance at cardiac rehabilitation. In addition, the pandemic is having an impact on lifestyle habits and mental health. Taken together, this has the potential to adversely impact the ability of practitioners and patients to adhere to treatment guidelines for the prevention of recurrent cardiovascular events. RECOMMENDATIONS: Every effort should be made to deliver safe, ongoing access to health care professionals and the use of evidenced based therapies in individuals with CVD. An increase in use of a range of electronic health platforms has the potential to transform secondary prevention. Integrating research programs that evaluate the utility of these approaches may provide important insights into how to develop more optimal approaches to secondary prevention beyond the pandemic.
