In Australia, the COVID-19 pandemic has resulted in the exponential growth in the delivery of telehealth services. Medicare data indicates that the majority of telehealth consultations have used the telephone, despite the known benefits of using video. The aim of this study was to understand the perceived quality and effectiveness of in-person, telephone and videoconsultations for cancer care. Data was collected via online surveys with consumers ( n = 1162) and health professionals ( n = 59), followed by semi-structured interviews with telehealth experienced health professionals ( n = 22) and consumers ( n = 18). Data were analysed using descriptive statistics and significance was tested using the chi-square test. A framework analysis and thematic analysis were used for qualitative data. Results indicate telehealth is suitable for use across the cancer care pathway. However, consumers and health professionals perceived videoconsultations facilitated visual communication and improved patients’ quality of care. The telephone was appropriate for short transactional consultations such as repeat prescriptions. Consumers were rarely given the choice of consultation modality. The choice of modality depended on a range of factors such as the type of consultation and stage of cancer care. Hybrid models of care utilising in-person, video and telephone should be developed and requires further guidance to promote the adoption of telehealth in cancer care.

Early supports to enhance social development in children with autism are widely promoted. While oxytocin has a crucial role in mammalian social development, its potential role as a medication to enhance social development in humans remains unclear. We investigated the efficacy, tolerability, and safety of intranasal oxytocin in young children with autism using a double-blind, randomized, placebo-controlled, clinical trial, following a placebo lead-in phase. A total of 87 children (aged between 3 and 12 years) with autism received 16 International Units (IU) of oxytocin (n = 45) or placebo (n = 42) nasal spray, morning and night (32 IU per day) for twelve weeks, following a 3-week placebo lead-in phase. Overall, there was no effect of oxytocin treatment over time on the caregiver-rated Social Responsiveness Scale (SRS-2) (p = 0.686). However, a significant interaction with age (p = 0.028) showed that for younger children, aged 3–5 years, there was some indication of a treatment effect. Younger children who received oxytocin showed improvement on caregiver-rated social responsiveness ( SRS-2). There was no other evidence of benefit in the sample as a whole, or in the younger age group, on the clinician-rated Clinical Global Improvement Scale (CGI-S), or any secondary measure. Importantly, placebo effects in the lead-in phase were evident and there was support for washout of the placebo response in the randomised phase. Oxytocin was well tolerated, with more adverse side effects reported in the placebo group. This study suggests the need for further clinical trials to test the benefits of oxytocin treatment in younger populations with autism.Trial registration www.anzctr.org.au (ACTRN12617000441314).

Cardiovascular disease remains the leading cause of death worldwide. Cardiovascular research has therefore never been more crucial. Cardiovascular researchers must be provided with a research environment that enables them to perform at their highest level, maximizing their opportunities to work effectively with key stakeholders to address this global issue. At present, cardiovascular researchers face a range of challenges and barriers, including a decline in funding, job insecurity and a lack of diversity at senior leadership levels. Indeed, many cardiovascular researchers, particularly women, have considered leaving the sector, highlighting a crucial need to develop strategies to support and retain researchers working in the cardiovascular field. In this Roadmap article, we present solutions to problems relevant to cardiovascular researchers worldwide that are broadly classified across three key areas: capacity building, research funding and fostering diversity and equity. This Roadmap provides opportunities for research institutions, as well as governments and funding bodies, to implement changes from policy to practice, to address the most important factors restricting the career progression of cardiovascular researchers.

Introduction Digital health interventions can be useful for the management of chronic disease. The aim of this study was to draw out universal themes to understand how people with chronic conditions experience digital health services, programmes, and interventions, and consequently, better inform future digital health delivery. Methods An umbrella review was conducted to identify qualitative systematic reviews reporting digital health experiences in chronic disease. Themes for each included review were independently extracted and appraised by two review authors. Data analysis was conducted using the Constant Comparative method. Results Twenty-two systematic reviews containing 240 individual studies were selected for inclusion. Mental health was the most common condition ( n = 5, 23%), followed by cancer ( n = 4, 18%) or a combination of chronic diseases ( n = 4, 18%). Common themes across the conditions were categorised under nine headings, including: (i) participation and engagement (strong usability and engagement vs reluctance to use digital health when these concepts are ignored), (ii) trust, confidence, and competence (users felt reassured, however technology illiteracy led to a perceived lack of control), (iii) perceived value, perceived effectiveness, transaction cost (gained from efficient aspects of digital health, but also lost through the burden of keeping up with data entry), (iv) perceived care quality (requiring tailoring and fostering motivation), (v) barriers and threats (related to technology risks and challenges), (vi) health outcomes (improved self-management capability), (vii) relationships (improved participant-health professional interaction, but interpersonal aspects such as face-to-face contact were lacking), (viii) unplanned benefit (where digital health often led to users feeling more empowered in their health journey), and (ix) diversity of experiences (reflecting ambivalence of experiences and discipline-specific experiences). Conclusion People with chronic conditions perceive digital health provides feelings of reassurance and the ability to self-manage their condition. While there is ambivalence across the participant experiences reported within the major themes, this umbrella review has outlined a need for future interventions that are user-friendly, flexible, and tailored to individual users. This will be best achieved through a co-design model, with the consumer actively involved in the planning and design of digital health products and services.

Since the COVID-19 pandemic onset, there has been exponential growth in the uptake of telehealth, globally. However, evidence suggests that people living in lower socioeconomic areas, cultural and linguistically diverse communities, people with disabilities, and with low health literacy are less likely to receive telehealth services. These population groups have disproportionately higher health needs and face additional barriers to healthcare access. Barriers that reduce access to telehealth further exacerbate existing gaps in care delivery. To improve equity of access to telehealth, we need to reduce the digital divide through a multi-stakeholder approach. This article proposes practical steps to reduce the digital divide and encourage equitable access to telehealth. Enabling more equitable access to telehealth requires improvements in digital health literacy, workforce training in clinical telehealth, co-design of new telehealth-enabled models of care, change management, advocacy for culturally appropriate services, and sustainable funding models.

Oncology ,General Medicine - Abstract
Cancer clinical trials have traditionally occurred in-person. However, the COVID-19 pandemic has forced adaptions of all aspects of cancer care (including clinical trials) so they can be delivered remotely. We aimed to quantify and qualify current use of telehealth and how it can be further improved and routinely integrated into cancer clinical trials in Australia.We used a mixed-method study design, involving surveys of 14 multi-site Collaborative Cancer Clinical Trial Groups members across Australia (n = 98) and qualitative interviews with trial administrators and clinicians (n = 21).The results of our study indicated a strong willingness to use telehealth for certain transactions of clinical trials because it was perceived as a way of increasing efficiency and reach of services. Hybrid models (including telehealth and in-person methods), which considered transaction, cancer type, and patient preferences were most favorable. Additionally, telehealth allowed for greater equity to access and reduced trial burden but interestingly had little effect on increased diversity and recruitment. Factors influencing telehealth service implementation and uptake included communication among trial stakeholders, training, and learning from the experience of others in the clinical trials community.Many but not all aspects of clinical trial care are appropriate to be delivered via telehealth. A hybrid approach provides flexibility to trial delivery and may support greater equity of access to trials in the future. Our findings and actionable recommendations support the need for greater planning, training, and guidelines to enable telehealth to be better integrated into clinical trials. Opportunities exist to expand the use of remote patient monitoring to enable more objective data collection from trial participants in the future.

Aims As we move into a new phase of the COVID-19 pandemic, cardiac and pulmonary services are considering how to sustain telehealth modalities long-term. It is important to learn from services that had greater telehealth adoption and determine factors that support sustained use. We aimed to describe how telehealth has been used to deliver cardiac and pulmonary rehabilitation services across Queensland, Australia. Methods and results Semi-structured interviews (n = 8) and focus groups (n = 7) were conducted with 27 cardiac and pulmonary clinicians and managers from health services across Queensland between June and August 2021. Interview questions were guided by Greenhalgh’s Non-adoption, Abandonment, Scale-up, Spread, and Sustainability framework. Hybrid inductive/deductive framework analysis elicited six main themes: (i) Variable levels of readiness; (ii) Greater telehealth uptake in pulmonary vs. cardiac rehabilitation; (iii) Safety and risk management; (iv) Client willingness—targeted support required; (v) Equity and access; and (vi) New models of care. We found that sustained integration of telehealth in cardiac and pulmonary rehabilitation will require contributions from all stakeholders: consumers (e.g. co-design), clinicians (e.g. shared learning), health services (e.g. increasing platform functionality), and the profession (e.g. sharing resources). Conclusion There are opportunities for telehealth programmes servicing large geographic areas and opportunities to increase programme participation rates more broadly. Centralized models of care serving large geographic areas could maximize sustainability with current resource limitations; however, realizing the full potential of telehealth will require additional funding for supporting infrastructure and workforce. Individuals and organizations both have roles to play in sustaining telehealth in cardiac and pulmonary services.

- Abstract
BackgroundRecent evidence indicates that high numbers of cardiovascular (CV) researchers have considered leaving the research and academic sector due to lack of job security and low funding success. Thus, there is an urgent need to develop solutions to support the retention of early- and mid-career researchers (EMCRs). Here, we aimed to explore the current challenges faced by CV EMCRs, identify solutions to support their career progression and retention, and define a pathway forward to provide a thriving CV EMCR culture in Australia.MethodsAustralian CV EMCRs (ResultsParticipants identified that current metrics only rewarded a narrow set of successes and did not support a collaborative culture. The current appraisal of career disruption in grant applications was identified as inadequate to address underrepresented researchers, such as women and those from culturally-diverse backgrounds. EMCRs proposed 92 solutions aimed at interpersonal, organisational or external levels, with capacity building and equitable opportunities as key focus areas.ConclusionPragmatic, cost-effective and implementable opportunities were identified to support the career progression of CV EMCRs to create a more sustainable, equitable and supportive workforce. This information can be used to strategically engage key stakeholders to enable CV EMCRs to thrive.

Health Informatics - Abstract
Introduction As COVID-19 restrictions reduce globally, services will determine what components of care will continue via telehealth. We aimed to determine the clinician, service, and system level factors that influence sustained use of telehealth and develop a framework to enhance sustained use where appropriate. Methods This study was conducted across 16 allied health departments over four health service facilities (Brisbane, Australia). It used a multi-method observational study design, involving telehealth service activity data from hospital administrative databases and qualitative interviews with allied health staff (n = 80). Data were integrated and analysed using Greenhalgh's Non-adoption, Abandonment, Scale-up, Spread, and Sustainability framework. Results Increased telehealth use during the peak COVID period reverted to in-person activity as restrictions eased. Telehealth is unlikely to be sustained without a clear strategy including determination of roles and responsibilities across the organisation. Clinician resistance due to forced adoption remains a key issue. The main motivator for clinicians to use telehealth was improved consumer-centred care. Benefits beyond this are needed to sustain telehealth and improvements are required to make the telehealth experience seamless for providers and recipients. Data were synthesised into a comprehensive framework that can be used as a blueprint for system-wide improvements and service enhancement or redesign. Discussion Sustainability of telehealth activity beyond the peak COVID period is unlikely without implementation strategies to address consumer, clinician, service, and system factors. The framework can inform how these strategies can be enacted. Whilst developed for allied health disciplines, it is likely applicable to other disciplines.

Health Informatics - Abstract
Aim To gain a better understanding of consumer experiences with and preferences for telephone and videoconference consultations (telehealth), and how these compare to traditional in-person consultations. Methods A national cross-sectional survey was administered to a representative sample of Australian adults who have received a telehealth service within the last year. Consumers were recruited by Qualtrics® through their online sampling service. The sample was representative of the broader Australian population according to gender, age, location (state/territory), and place of residence (urban or remote). Information on demographics (e.g., age, gender, employment status), recent telehealth experience, and preferences for consultation modality was collected. To measure preferences consumers were asked to indicate which modality they would prefer (in-person, telephone, or videoconference) for different scenarios. These included consultations of various time lengths, and for the top ten conditions for which individuals sought a general practitioner. Results A total of 1069 consumers completed the survey. When consumers were asked to describe their most recent telehealth appointment, most were for follow-up appointments (67%) and completed by telephone (77%) rather than by videoconference, and with a general practitioner (75%). In-person consultations at a clinic were the top preference in all clinical scenarios presented, except when needing a prescription or to receive test results. In these cases, a telephone consultation was the preferred modality. Inexperience with videoconference and duration of consultation influenced preference for consultation mode. Consumers preferred to have short consultations of around five minutes done by telehealth (telephone or videoconference), while they preferred in-person for longer consultations (up to 60 minutes). Conclusions Many Australians have used telehealth in the past year to access healthcare, with telephone being the most common form of communication. Given the option and the experience to date, consumers prefer telephone when consultations related to either prescriptions or test results. Experience with videoconference for consultations increased consumer preferences for using it for future consultations.

To enable services to be provided at a distance during the COVID-19 pandemic, outpatient pharmacy services in Australia underwent near-immediate reform by moving to telehealth, including telephone and video consults.To investigate how telehealth was used in a metropolitan outpatient pharmacy setting before and after the start of the COVID-19 restrictions and the various influences on the uptake of phone and video modalities.A multi-methods approach was used including: (1) quantifying administrative activity data between July 2019 to December 2020 and, (2) semi-structured interviews with key stakeholders (n = 34).Activity data: Between July 2019 to December 2020 16,377 outpatient pharmacy consults were provided. Of these, 13,543 (83%) were provided in-person, 2,608 (16%) by telephone and 226 (1.4%) by video consult. COVID-19 impacted how these services were provided with telephone activity more than four-times higher in April 2020 than March 2020 and slight increases in video consults. Pharmacists have heavily favoured using the telephone despite the recommendation that video consults be used as the primary mode of contact and that telephone only be used when a video consult was not possible. As soon as COVID-19 restrictions eased, clinicians gradually returned to in-person appointments, maintaining some use of telephone and very limited use of video consult. Semi-structured interviews: Whilst clinicians recognised the potential benefits of video consults, challenges to routine use included the additional administrative and planning work required pre-consult, perceptions that patients were unable to use the technology, and the belief that in-person care was 'better' and that the telephone was easier.Organisational strategies that encouraged the use of video over telephone (e.g. through financial incentives) did not appear to influence clinicians' choice of care modality. Implementation studies are required to co-develop solutions to embed telehealth options into outpatient pharmacy settings that provide the best experience for both patients and clinicians.

There is an increasing interest in using magnetic resonance imaging (MRI) as a tool for precision medicine in autism spectrum disorder (ASD). This study investigated the feasibility of MRI scanning in a large comprehensive, inclusive and test heavy clinical trial for children (aged 3-12 years) with ASD, without functioning constraints for participation. Of the 71 participants enrolled who consented to the MRI, 24 participants (38%) successfully completed an MRI scan at baseline along with other assessments. This scanning followed a familiarization procedure at two preceding visits. At post-treatment, 21 participants successfully completed the MRI scan. This study highlights the challenge of completing MRI assessments in ASD populations when conducted as one of a number of tests in a clinical trial.

Differential diagnosis in adult cohorts with social difficulty is confounded by comorbid mental health conditions, common etiologies, and shared phenotypes. Identifying shared and discriminating profiles can facilitate intervention and remediation strategies. The objective of the study was to identify salient features of a composite test battery of cognitive and mood measures using a machine learning paradigm in clinical cohorts with social interaction difficulties. We recruited clinical participants who met standardized diagnostic criteria for autism spectrum disorder (ASD: n = 62), early psychosis (EP: n = 48), or social anxiety disorder (SAD: N = 83) and compared them with a neurotypical comparison group (TYP: N = 43). Using five machine-learning algorithms and repeated cross-validation, we trained and tested classification models using measures of cognitive and executive function, lower- and higher-order social cognition and mood severity. Performance metrics were the area under the curve (AUC) and Brier Scores. Sixteen features successfully differentiated between the groups. The control versus social impairment cohorts (ASD, EP, SAD) were differentiated by social cognition, visuospatial memory and mood measures. Importantly, a distinct profile cluster drawn from social cognition, visual learning, executive function and mood, distinguished the neurodevelopmental cohort (EP and ASD) from the SAD group. The mean AUC range was between 0.891 and 0.916 for social impairment versus control cohorts and, 0.729 to 0.781 for SAD vs neurodevelopmental cohorts. This is the first study that compares an extensive battery of neuropsychological and self-report measures using a machine learning protocol in clinical and neurodevelopmental cohorts characterized by social impairment. Findings are relevant for diagnostic, intervention and remediation strategies for these groups.

- Abstract
GABA is the primary inhibitory neurotransmitter in the brain, and is essential to the balance of cortical excitation and inhibition. Reductions in GABA are proposed to result in an overly excitatory cortex that may cause, or contribute to, symptoms of Autism Spectrum Disorder (ASD).This study employed a cross-sectional design to explore GABA+ differences in ASD and the impact of age, comparing 4-12 year olds with ASD (N=24) to typically developing children (N=35). GABA+ concentration was measured using edited magnetic resonance spectroscopy in the left parietal lobe.This study used mixed models to investigate group differences between children with ASD and typically developing children. There was a significant difference in GABA+ levels between the groups, a significant effect of age and interaction between age and diagnostic group. The ASD group showed an association between GABA+ and age, with GABA+ levels gradually increasing with age (r=0.59, p=0.003). Typically developing children did not show age-related change in GABA+ concentration (r=0.09, p=0.60). By the age of 9, children with ASD showed GABA+ levels that were comparable to their typically developing control peers. This study suggests that children with ASD have initially lower levels of GABA+ in the left parietal lobe compared to typically developing children, and that these initially lower levels of GABA+ increase with age in ASD within this region. It is suggested that this developmental shift of GABA levels within the left parietal lobe provides a possible explanation for the previously found reductions in childhood that does not persist in adults.
