Abstract: By performing a systematic study of the Hénon map, we find low-period sinks for parameter values extremely close to the classical ones. This raises the question whether or not the well-known Hénon attractor—the attractor of the Hénon map existing for the classical parameter values—is a strange attractor, or simply a stable periodic orbit. Using results from our study, we conclude that even if the latter were true, it would be practically impossible to establish this by computing trajectories of the map.

Abstract: Objective To describe the change in telemental health service volume that resulted from the introduction of the Medicare Benefits Schedule (MBS) item numbers in 2020 for services provided by psychologists and psychiatrists in Australia for a 3-year period, from January 2019 to December 2021. Methods Quarterly MBS activity and cost data for mental health services provided by consultant psychiatrists, clinical psychologists, and psychologists between January 2019 and December 2021 were extracted from the MBS statistics website. Data were grouped by profession and delivery mode (in-person, telephone or videoconference) and reported using activity counts. Descriptive analysis and interrupted time-series regression analysis were conducted. Specific descriptive explorations were also conducted for psychiatrists, including: new client consultations, review or general consultations, and group consultations. Results The delivery of mental health services by telehealth (telemental health) during the pandemic has increased (P 0.0001). When the pandemic started in March 2020, telemental health services provided by psychiatrists and psychologists increased from a combined 1–2% per quarter to 29% videoconference and 20% telephone in quarter two 2020. After the onset of the pandemic, videoconference remained the primary form of telehealth for these professions. However, the telephone accounted for approximately a third of the telehealth activity after the new item numbers were introduced. Conclusion Telemental health services are more likely to be conducted by videoconference than by telephone. The observed increase in telehealth service activity confirms how crucial appropriate funding models are to the sustainability of telehealth services in Australia. The growth in telehealth was used to support people with mental health conditions in Australia.

Abstract: Clinical facilitation is an established strategy for introducing innovation into clinical practice. The Queensland Centre for Perinatal and Infant Mental Health has used clinical facilitation to establish a telehealth service to support perinatal and infant mental health in regional, rural and remote areas of the Australian state of Queensland. The aim of this study is to explore the role of clinical facilitation in implementing and sustaining the telehealth service. Semi-structured interviews were conducted with 14 remote-site users of the telehealth service. Interviews were analysed using thematic analysis. Two dominant themes emerged: unmet need and service visibility. The study confirms the usefulness of telehealth as a way to address unmet need for specialist mental health services in regional, rural and remote areas. The study also provides evidence that a telehealth service with intermittent demand requires a consistent clinical facilitator, to keep the service visible to remote-site clinicians and maintain awareness of the service as a referral option. Previous research has identified the importance of clinical facilitation in initial service implementation. This study demonstrates the necessity of clinical facilitation for ongoing service provision. Facilitation is likely to be more important where the telehealth service responds to intermittent or infrequent clinical need, compared with high-volume services where clinics are conducted routinely.

Abstract: The 2019 coronavirus pandemic (COVID-19) has resulted in tremendous growth in telehealth services in Australia and around the world. The rapid uptake of telehealth has mainly been due to necessity – following social distancing requirements and the need to reduce the risk of transmission. Although telehealth has been available for many decades, the COVID-19 experience has resulted in heightened awareness of telehealth amongst health service providers, patients and society overall. With increased telehealth uptake in many jurisdictions during the pandemic, it is timely and important to consider what role telehealth will have post-pandemic. In this article, we highlight five key requirements for the long-term sustainability of telehealth. These include: (a) developing a skilled workforce (b) empowering consumers (c) reforming funding (d) improving the digital ecosystems and (e) integrating telehealth into routine care.

Abstract: 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. 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. Twenty-two systematic reviews containing 240 in idual 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) ersity of experiences (reflecting ambivalence of experiences and discipline-specific experiences). 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 in idual 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.

Abstract: Telepalliative care services enable clinicians to provide essential palliation services to people with a life-limiting illness in or closer to home. This study aims to explore the costs, service activity and staff experiences resulting from the introduction of telehealth in a community palliative care service in Queensland, Australia. Pre- and post-activity and cost data from the 2016–2017 and 2019–2020 financial years were examined and staff members interviewed. Accounting for inflation and standard wage increases, the labour costs before and after the addition of telehealth were approximately equal. There were small variations in non-labour costs, but these were not directly attributable to the expansion of the telehealth services. Overall, the service activity increased by 189% for standard doctor and nurse consultations, due to the increased efficiency of telehealth compared to the previous outreach (travel) model. Thematic analysis of the staff interview data generated an overarching theme of Increased Job Satisfaction which staff attributed to the patient-centred nature of the telepalliative care service, the increased peer support and increased professional development. Compared with the traditional in-person service, the new telehealth-supported model resulted in equivalent costs, greater efficiency by allowing palliative care to reach more patients and improved staff job satisfaction.

Abstract: Inadequate knowledge and skills and a lack of confidence to provide care have been identified as major unmet needs for carers of people with brain cancer. An online intervention was developed to address the unmet needs of carers of people with high-grade glioma. Ten carers evaluated the intervention through multiple methods. Acceptability and usability were measured through online data analytics (unique page views, time on page), surveys, and interviews. Questionnaires measured potential impacts on distress (Distress Thermometer), depression, anxiety (Hospital Anxiety and Depression Scale), carer competence (Carer Competence Scale), carer preparedness (Caregiving Preparedness Scale), unmet needs (Supportive Care Needs Scale – Brain Tumor Specific for carers), usability and acceptability (USE). Results suggested the intervention had high levels of usability (usability scales’ means range = 5.1 to 6.7 out of 7) and acceptability (M = 76.3/100). Correlations indicated the potential to impact depression. Qualitative findings highlighted benefits of the intervention as a comprehensive reliable resource that could validate and normalize carer experiences. Interview findings guided further improvements (eg, additional carer videos, content organization). The study indicated high acceptability and usability of an online intervention for carers of people with high-grade glioma. This exploratory study also provided preliminary indications of a potential to decrease depression. However, a more robust, potentially longitudinal, investigation is needed with a larger and broader s le. Informed by this study, the intervention has been amended and a randomized controlled trial will further evaluate the enhanced intervention.

Abstract: 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. A national cross-sectional survey was administered to a representative s le of Australian adults who have received a telehealth service within the last year. Consumers were recruited by Qualtrics® through their online s ling service. The s le 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 in iduals sought a general practitioner. 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). 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.

Abstract: The question of coexisting attractors for the Hénon map is studied numerically by performing an exhaustive search in the parameter space. As a result, several parameter values for which more than two attractors coexist are found. Using tools from interval analysis, we show rigorously that the attractors exist. In the case of periodic orbits, we verify that they are stable, and thus proper sinks. Regions of existence in parameter space of the found sinks are located using a continuation method the basins of attraction are found numerically.

Abstract: The delivery of specialist health services to people living in Indigenous communities is an important challenge. Specialist diabetes outpatient clinics may be delivered via a patient travelling to a metropolitan hospital, during an outreach clinic, or by telehealth. The aim of this study was to compare the costs and consequences of different service models for delivering specialist diabetes clinics for a remote Indigenous community. Patient travel, outreach and telehealth clinic models were compared using a cost-consequence analysis principles. The setting was Cunnamulla, a remote Indigenous community in Western Queensland. Costs were calculated by quantifying the staff resources and travel costs for each clinic model. Costs were reported in Australian dollars and reported from the health service perspective. The marginal cost per patient for each clinic were $692 for patient travel, $482 for the outreach and $284 for telehealth. If a patient travel appointment was replaced with telehealth, approximately $517 in costs for patient travel reimbursement would be avoided. While replacing an entire outreach clinic with a telehealth clinic would reduce costs by approximately $3961. The marginal cost of patient travel to a metropolitan clinic and outreach clinic appointments was greater than telehealth. Telehealth is unlikely to completely replace the need for patient travel or outreach clinics. However, replacing a proportion of these appointments with telehealth may reduce the overall costs of providing specialist diabetes care in remote communities. Telehealth may have advantages beyond economic as it reduces the time away from usual activities for both the patient and endocrinologist.

Abstract: Telehealth can effectively increase access to specialist care and reduce the need for travel. The Geri-Connect service was established in 2017 to support people living in residential aged care facilities in regional Victoria, Australia. Using the Model for the Assessment of Telemedicine, an evaluation of the Geri-Connect service identified service activity patterns and factors associated with uptake. Service activity from 2017 to 2020 and 10 semi-structured, key stakeholder interviews were captured and analysed. Between 2017 and 2020, video consultations were provided to 53 residential aged care facilities. Sustained growth (over 178%) and strong stakeholder acceptance highlight the effectiveness of this telegeriatric service. Four recommendations provide opportunities to further enhance service delivery including: implementation of an integrated health information system systematic evaluation of service impact on stakeholders and residents, auditing and subsequent provision of targeted training and regular auditing of software and hardware. Additionally, the need to augment fixed room hardware with mobile telehealth systems would increase access for residents with mobility problems. Dedicated personnel of the centralised team are best suited to implementing the recommendations. Whilst the provision of routine telehealth services into residential aged care facilities is challenging, the Geri-Connect service demonstrates that telehealth can be effectively provided to residential aged care facility residents needing specialist geriatric care.

Abstract: Studies of dementia knowledge (including dementia risk reduction) in health‐care trainees highlight varying levels of understanding across countries and disciplines. This draws attention to the need for a well‐trained health workforce with the knowledge to ch ion and implement such strategies. This study (a) assessed dementia knowledge and health literacy among a s le of Australian health‐care students, (b) identified modality preferences of digital health interventions addressing dementia prevention and (c) examined potential relationships among health literacy, dementia knowledge, dementia prevention knowledge and a student's preferences for different digital health modalities. A cross‐sectional survey assessed dementia knowledge and health literacy in 727 health students across 16 Australian universities representing both metropolitan and regional cohorts. The All Aspects of Health Literacy Scale and the Dementia Knowledge Assessment Scale were administered. Questions about the perceived effectiveness of strategies and preferred digital health modalities for dementia prevention/risk reduction were asked. The students had relatively high health literacy scores. However, dementia knowledge and evidence‐based dementia prevention knowledge were average. Only 7% claimed knowledge of available dementia‐related digital health interventions. Associations among health literacy, dementia knowledge and dementia prevention, with recommendations for different digital modalities, are presented. Health‐related degrees need to increase dementia knowledge, health literacy and knowledge of effective dementia‐related digital health interventions. It is imperative to equip the future health workforce amid an ageing population with increased dementia rates and where evidence‐based digital health interventions will increasingly be a source of support.

Abstract: High rates of dementia among Australian First Nations’ peoples have resulted in an increased demand for dementia knowledge and skills among the primary health care professionals in these communities. The Dementia Extension for Community Healthcare Outcomes (ECHO) program aims to be a culturally safe way of increasing local health workforce capacity by facilitating dementia knowledge, skills and confidence among primary care professionals in First Nations community settings. Dementia ECHO is based on the international evidence-based telementoring programme, Project Extension for Community Healthcare Outcomes. Every Dementia ECHO session is delivered by videoconference and comprises a specialist-led presentation and a case discussion from a primary care health service participant. The aims of this study were to assess the uptake and reach of Dementia ECHO examine the perceived importance of dementia care and dementia education among Aboriginal and Torres Strait Islander Community Controlled Health Service staff and evaluate the potential impact of Dementia ECHO on health service staff pertaining to dementia knowledge, confidence to provide dementia care and professional isolation. Dementia ECHO service activity data maintained by the programme providers was reviewed to determine uptake and reach. A pre-implementation survey examined Aboriginal and Torres Strait Islander Community Controlled Health Service staff perspectives on the importance of dementia education and the priority of a range of health issues. After each Dementia ECHO session, a brief online survey gathered quantitative and qualitative data regarding the potential impact of the session. Of 30 completed pre-implementation surveys, all staff rated dementia education as either very important or important. Salient themes highlighting why it is important are presented. When asked to rank six different health priorities, dementia ( n = 10) and chronic disease ( n = 10) were placed as the top priority. The brief post-session feedback provided 44 complete survey responses demonstrating: perceived improvement in dementia knowledge and skills (88.4%) increased confidence to provide dementia care (83%) and a reduction in professional isolation (88%). Dementia ECHO addresses a gap in dementia education that is much needed in health professionals with increasing numbers of First Nations people living with dementia. This current study shows that attending an evidence-based telementoring programme, such as Dementia ECHO, can increase dementia knowledge and confidence to care for someone living with dementia and their families.

Abstract: Changing trends demonstrate that women, in several economically developed countries, are drinking at higher levels than ever before. This study applied an extended Theory of Planned Behavior (TPB), including self-identity, to examine women's intentions to consume alcohol. Women (N = 1069) aged 18-87 years, completed a questionnaire measuring their intentions to engage in binge drinking and frequent drinking. As research indicates that drinking trends are a function of age, hierarchical multiple regressions were conducted separately for four age groups (18-24, 25-34, 35-44, 45, and above). Results supported the predictive utility of the TPB, (particularly Attitudes and Perceived Behavioral Control). Across the age groups, the final models explained between 48% and 62% of the variance in intentions to binge drink and between 33% and 51% of the variance in intentions to drink frequently. Subjective norms were significant associated with the youngest group (18-24 years) and the oldest group (45+ years). Self-identity was significantly associated with intentions to binge drink in younger women. Implications are discussed with regard to the predictive utility of an extended TPB to include self-identity in determining women's intentions to consume alcohol. Key factors that influence women's decisions to engage in risky drinking behaviors have been underlined to inform future interventions.

Abstract: We show that, for a certain class of systems, the problem of establishing the existence of periodic orbits can be successfully studied by a symbolic dynamics approach combined with interval methods. Symbolic dynamics is used to find approximate positions of periodic points, and the existence of periodic orbits in a neighborhood of these approximations is proved using an interval operator. As an ex le, the Lorenz system is studied a theoretical argument is used to prove that each periodic orbit has a distinct symbol sequence. All periodic orbits with the period p ≤ 16 of the Poincaré map associated with the Lorenz system are found. Estimates of the topological entropy of the Poincaré map and the flow, based on the number and flow-times of short periodic orbits, are calculated. Finally, we establish the existence of several long periodic orbits with specific symbol sequences.

Abstract: Telehealth use within allied health services currently lacks structure and consistency, ultimately affecting who can, and cannot, access services. This study aimed to investigate the factors influencing allied health professionals’ (AHP) selection of consumers and appointments for telehealth. This study was conducted across 16 allied health departments from four Australian hospitals. Semi-structured focus groups were conducted with 58 AHPs. Analysis was underpinned by Qualitative Description methodology with inductive coding guided by Braun and Clarke's thematic analysis approach. Six themes were identified that influenced AHPs’ evaluation of telehealth suitability and selection of consumers. These included the following: (1) ease, efficiency and comfort of telehealth for clinicians (2) clear benefits of telehealth for the consumer, yet the consumers were not always given the choice (3) consumers’ technology access and ability (4) establishing and maintaining effective therapeutic relationships via telehealth (5) delivering clinically appropriate and effective care via telehealth and (6) external influences on telehealth service provision. A further theme of ‘assumption versus reality’ was noted to pervade all six themes. Clinicians remain the key decision makers for whether telehealth is offered within allied health services. Ease and efficiency of use is a major driver in AHP's willingness to use telehealth. Assumptions and pre-conceived frames-of-reference often underpin decisions to not offer telehealth and present major barriers to telehealth adoption. The development of evidence-based, decision-support frameworks that engage the consumer and clinician in determining when telehealth is used is required. Services need to actively pursue joint decision-making between the clinician and consumer about service delivery preferences.
