Using two qualitative data sources: free-text responses to an open-ended question of an online survey and subsequent interviews and focus groups, we explored perceptions and attitudes toward COVID-19 vaccination among health professional students enrolled in Australian universities during the pandemic with data collected from October 2021 to April 2022. Students provided free-text responses to the open-ended question (n = 313) in the online survey and participated in interviews or focus groups (n = 17). Data analysis revealed three themes, including perceptions of COVID-19 seriousness and the risk of contracting the virus, information dissemination, and attitudes toward the vaccine mandate. The study identified evolving perceptions of COVID-19 seriousness among Australian health professional students and their sentiments toward the vaccine mandate. There is a need to ensure the quality of information dissemination related to the vaccine mandate. This may not only support students' uptake of mandatory vaccination but also provide a means for them to address vaccination with healthcare consumers and patients. [ABSTRACT FROM AUTHOR]

This paper aims to empower cardiovascular (CV) researchers by promoting diversity, equity, and inclusion (DE&I) principles throughout the research cycle. It defines DE&I and introduces practical strategies for implementation in recruitment, retention, and team dynamics within CV research. Evidence-based approaches supporting underrepresented populations' participation are outlined for each research phase. Emphasizing the significance of inclusive research environments, the paper offers guidance and resources. We invite CV researchers to actively embrace DE&I principles, enhancing research relevance and addressing longstanding CV health disparities. [ABSTRACT FROM AUTHOR]

Using a cross-sectional online survey we investigated knowledge, attitudes, and risk perception about COVID-19 vaccination and identified factors influencing vaccine uptake among Australian health professional students from October 2021 to January 2022. We analysed data from 1114 health professional students from 17 Australian universities. Most participants were enrolled in nursing programs (n = 958, 86.8%), and 91.6% (n = 858) of the participants received COVID-19 vaccination. Approximately 27% believed COVID-19 was no more serious than seasonal influenza and that they had a low risk of acquiring COVID-19. Nearly 20% disagreed that COVID-19 vaccines in Australia were safe and perceived they were at higher-risk of acquiring COVID infection than the general population. Higher-risk perception viewing vaccination as their professional responsibility, and vaccine mandate strongly predicted vaccination behaviour. Participants consider COVID-19 information from health professionals, government websites, and World Health Organization as the most trusted information sources. The findings highlight that healthcare decision-makers and university administrators need to monitor students' hesitancy with vaccination to improve students' promotion of the vaccination to the general population.

Aims To compare the frailty prevalence and predictive performance of six frailty instruments in adults with heart failure and determine the feasibility of study methods. Methods and results Prospective cohort pilot study. Adults aged 18 years or older with a confirmed diagnosis of heart failure in Sydney, New South Wales, Australia. The Frailty Phenotype; the Survey of Health, Ageing, and Retirement in Europe Frailty Instrument (SHARE-FI); St Vincent's Frailty instrument; St Vincent's Frailty instrument plus cognition and mood; The Fatigue, Resistance, Ambulation, Illnesses, and Loss of Weight (FRAIL) scale; and the Deficit Accumulation Index (DAI) were compared. Multiple logistic regression was used to develop six frailty instrument models to evaluate the association between each frailty instrument and composite all-cause rehospitalization and mortality at 12 months. One hundred and thirty-one patients were included with a mean age of 54 [± 14(SD)]. Frailty prevalence ranged from 33 to 81%. All instruments except one (the FRAIL scale) appeared to signal an increased odds of rehospitalization and/or mortality, yet these results were non-significant. The six frailty instrument models displayed sensitivity between 88–92% and C-statistic values of 0.71–0.73, suggesting satisfactory discrimination. Conclusion The prevalence of frailty varied across six frailty instruments yet was in the higher range despite a 'younger' heart failure cohort. Further research is required to confirm the psychometric properties of these instruments for routine clinical use in an adequately powered and more diverse heart failure cohort.

Purpose: Health related quality of life (HRQoL) is rarely routinely measured in the clinical setting. In the absence of patient reported data, clinicians rely on proxy and informal estimates to support clinical decisions. This study compares clinician estimates (proxy) with patient reported HRQoL in patients with advanced heart failure and examines factors influencing discrepancies. Methods: Seventy-five patients with heart failure, (22 females, 53 males) completed the EQ-5D-5L questionnaire. Thirty-nine clinicians (11 medical, 23 nursing, 5 allied health) completed the proxy version (V1) producing 194 dyads. Correlation was assessed using Spearman's rank tests, systematic bias was examined with Bland–Altman analyses. Inter-rater agreement at the domain level, was investigated using linear weighted Kappa statistics while factors influencing the IRG were explored using independent student t-tests, analysis of variance and regression. Results: There was a moderate positive correlation between clinician HRQoL estimates and patient reported utility (r = 0.38; p <.0005). Mean clinician estimates were higher than patient reported utility (0.60 vs 0.54; p = 0.008), with significant underestimation of reported problems apparent in three of the five EQ-5D-5L domains. Patient sex (female), depressed mood and frailty were all associated with an increased inter-rater gap. Conclusion: Clinicians in this sample overestimated HRQoL. Factors affecting the inter-rater gap, including sex and depression, support formal HRQoL screening to enhance clinical conversations and decision making. The discrepancy also supports regulatory restriction on the use of expert opinion in the development of QALYs in health economic analysis. [ABSTRACT FROM AUTHOR]

Background: Frailty is an important predictive measure of mortality and rehospitalisation in people with heart failure. To date, there are no frailty instruments validated for use in people with heart failure. Aim: The aim of this study was to evaluate the convergent and discriminant validity of three versions of the frailty phenotype in those with heart failure. Methods: A single site, prospective cohort study was undertaken among individuals with a confirmed diagnosis of heart failure. Frailty was assessed concurrently using three versions of the frailty phenotype: the original frailty phenotype and two modified versions; the Survey of Health, Ageing and Retirement in Europe frailty instrument (SHARE-FI) and the St Vincent's frailty instrument. Convergent and discriminant validity were assessed by reporting the correlations between each version and related heart failure subconstructs, and by evaluating the ability of each version to discriminate between normal and abnormal scores of other physical and psychosocial scales specific to heart failure-related subconstructs. Results: The New York Heart Association classes were moderately correlated with the St Vincent's frailty instrument (r =0.47, P ⩽0.001), SHARE-FI (r =0.42, P ⩽0.001) and the frailty phenotype (r =0.42, P ⩽0.001). The SHARE-FI and the St Vincent's frailty instrument were both able to discriminate consistently between normal and abnormal scores in three out of five of the physical and psychosocial subconstructs that were assessed. The SHARE-FI was also able to discriminate between inpatients and outpatients who were classified as frail. Conclusions: Both the SHARE-FI and the St Vincent's frailty instrument displayed good convergent and discriminant validity. [ABSTRACT FROM AUTHOR]

Objectives: The aim of this study was to describe patient level costing methods and develop a database of healthcare resource use and cost in patients with AHF receiving ventricular assist device (VAD) therapy.Methods: Patient level micro-costing was used to identify documented activity in the years preceding and following VAD implantation, and preceding heart transplant for a cohort of seventy-seven consecutive patients listed for heart transplantation (2009-12). Clinician interviews verified activity, established time resource required for each activity, and added additional undocumented activities. Costs were sourced from the general ledger, salary, stock price, pharmacy formulary data, and from national medical benefits and prostheses lists. Linked administrative data analyses of activity external to the implanting institution, used National Weighted Activity Units (NWAU), 2014 efficient price, and admission complexity cost weights and were compared with micro-costed data for the implanting admission.Results: The database produced includes patient level activity and costs associated with the seventy-seven patients across thirteen resource areas including hospital activity external to the implanting center. The median cost of the implanting admission using linked administrative data was $246,839 (interquartile range [IQR] $246,839-$271,743), versus $270,716 (IQR $211,740-$378,482) for the institutional micro-costing (p = .08).Conclusions: Linked administrative data provides a useful alternative for imputing costs external to the implanting center, and combined with institutional data can illuminate both the pathways to transplant referral and the hospital activity generated by patients experiencing the terminal phases of heart failure in the year before transplant, cf-VAD implant, or death.

In this 'paired' case report, we describe two heart transplants performed 3 days apart at our centre. Both cases involved very prolonged transportation time of the donor heart. In one case, the donor heart was transported in an ice chest, while in the other case the organ was transported using a normothermic ex vivo perfusion ( NEVP) system. The additional retrieval costs incurred by the use NEVP were more than offset by the reduction in subsequent inpatient costs. [ABSTRACT FROM AUTHOR]
