Understanding the perspectives and needs of multiple stakeholders: Identifying key elements of a digital health intervention to protect against environmental hazards.

AirRater is a free environmental health smartphone app developed and available in Australia that collects individual health data and disseminates environmental hazard information to populations. Following previous evaluations with app users, the aim of this study was to better understand how clinicians, government agency and non-government advocacy group representatives perceive an app designed to reduce the impacts of environmental hazards on individual and public health. Nine government agency and non-government advocacy group representatives, along with 11 clinicians based in Australia participated in a semi-structured interview or focus group to explore perspectives on AirRater. Interview and focus group data were transcribed and analysed using the qualitative data analysis software NVivo. Results indicate that for clinicians, apps like AirRater can add value as an educational, patient self-management and diagnostic tool. For government and peak bodies, apps can add value by addressing environmental health literacy and monitoring and forecasting gaps, as well as supporting advocacy efforts and public health surveillance. We conclude that environmental health smartphone apps can support a range of stakeholders to achieve shared goals and priorities related to individual and public health outcomes. Further research is needed to better understand how apps could be embedded into clinical practice and policy settings.

Evaluating User Preferences, Comprehension, and Trust in Apps for Environmental Health Hazards: Qualitative Case Study.

BACKGROUND: Climate change is projected to increase environmental health hazard risks through fire-related air pollution and increased airborne pollen levels. To protect vulnerable populations, it is imperative that evidence-based and accessible interventions are available. The environmental health app, AirRater, was developed in 2015 in Australia to provide information on multiple atmospheric health hazards in near real time. The app allows users to view local environmental conditions, and input and track their personal symptoms to enable behaviors that protect health in response to environmental hazards. OBJECTIVE: This study aimed to develop insights into users' perceptions of engagement, comprehension, and trust in AirRater to inform the future development of environmental health apps. Specifically, this study explored which AirRater features users engaged with, what additional features or functionality needs users felt they required, users' self-perception of understanding app information, and their level of trust in the information provided. METHODS: A total of 42 adult AirRater users were recruited from 3 locations in Australia to participate in semistructured interviews to capture location- or context-specific experiences. Participants were notified of the recruitment opportunity through multiple avenues including newsletter articles and social media. Informed consent was obtained before participation, and the participants were remunerated for their time and perspectives. A preinterview questionnaire collected data including age range, any preexisting conditions, and location (postcode). All participant data were deidentified. Interviews were recorded, transcribed, and analyzed using thematic analysis in NVivo 12 (QSR International). RESULTS: Participants discussed app features and functionality, as well as their understanding of, and trust in, the information provided by the app. Most (26/42, 62%) participants used and valued visual environmental hazard features, especially maps, location settings, and hazard alerts. Most (33/42, 78%) found information in the app easy to understand and support their needs, irrespective of their self-reported literacy levels. Many (21/42, 50%) users reported that they did not question the accuracy of the data presented in the app. Suggested enhancements include the provision of meteorological information (eg, wind speed or direction, air pressure, UV rating, and humidity), functionality enhancements (eg, forecasting, additional alerts, and the inclusion of health advice), and clarification of existing information (eg, symptom triggers), including the capacity to download personal summary data for a specified period. CONCLUSIONS: Participants' perspectives can inform the future development of environmental health apps. Specifically, participants' insights support the identification of key elements for the optimal development of environmental health app design, including streamlining, capacity for users to customize, use of real time data, visual cues, credibility, and accuracy of data. The results also suggest that, in the future, iterative collaboration between developers, environmental agencies, and users will likely promote better functional design, user trust in the data, and ultimately better population health outcomes.

Characterising non-linear associations between airborne pollen counts and respiratory symptoms from the AirRater smartphone app in Tasmania, Australia: A case time series approach.

Pollen is a well-established trigger of asthma and allergic rhinitis, yet concentration-response relationships, lagged effects, and interactions with other environmental factors remain poorly understood. Smartphone technology offers an opportunity to address these challenges using large, multi-year datasets that capture individual symptoms and exposures in real time. We aimed to characterise associations between six pollen types and respiratory symptoms logged by users of the AirRater smartphone app in Tasmania, Australia. We analyzed 44,820 symptom reports logged by 2272 AirRater app users in Tasmania over four years (2015-2019). With these data we evaluated associations between daily respiratory symptoms and atmospheric pollen concentrations. We implemented Poisson regression models, using the case time series approach designed for app-sourced data. We assessed potentially non-linear and lagged associations with (a) total pollen and (b) six individual pollen taxa. We adjusted for seasonality and meteorology and tested for interactions with particulate air pollution (PM2.5). We found evidence of non-linear associations between total pollen and respiratory symptoms for up to three days following exposure. For total pollen, the same-day relative risk (RR) increased to 1.31 (95% CI: 1.26-1.37) at a concentration of 50 grains/m3 before plateauing. Associations with individual pollen taxa were also non-linear with some diversity in shapes. For all pollen taxa the same-day RR was highest. The interaction between total pollen and PM2.5 was positive, with risks associated with pollen significantly higher in the presence of high concentrations of PM2.5. Our results support a non-linear response between airborne pollen and respiratory symptoms. The association was strongest on the day of exposure and synergistic with particulate air pollution. The associations found with Dodonaea and Myrtaceae highlight the need to further investigate the role of Australian native pollen types in allergic respiratory disease.

Environmental Hazards and Behavior Change: User Perspectives on the Usability and Effectiveness of the AirRater Smartphone App.

AirRater is a free smartphone app developed in 2015, supporting individuals to protect their health from environmental hazards. It does this by providing (i) location-specific and near real-time air quality, pollen and temperature information and (ii) personal symptom tracking functionality. This research sought to evaluate user perceptions of AirRater's usability and effectiveness. We collected demographic data and completed semi-structured interviews with 42 AirRater users, identified emergent themes, and used two frameworks designed to understand and support behavior change-the Behavior Change Wheel (BCW) and the Protective Action Decision Model (PADM)-to interpret results. Of the 42 participants, almost half indicated that experiencing symptoms acted as a prompt for app use. Information provided by the app supported a majority of the 42 participants to make decisions and implement behaviors to protect their health irrespective of their location or context. The majority of participants also indicated that they shared information provided by the app with family, friends and/or colleagues. The evaluation also identified opportunities to improve the app. Several study limitations were identified, which impacts the generalizability of results beyond the populations studied. Despite these limitations, findings facilitated new insights into motivations for behavior change, and contribute to the existing literature investigating the potential for smartphone apps to support health protection from environmental hazards in a changing climate.

What are the health and socioeconomic impacts of allergic respiratory disease in Tasmania?

Objective The aim of this study was to quantify the direct and indirect costs of asthma and allergic rhinitis (AR) for 2018 in Tasmania. Methods We used publicly available data, and Tasmanian-specific values where available, to estimate direct and indirect costs of both diseases. Direct costs included outcomes such as emergency department (ED) presentations, hospitalisations, general practice visits and medication use. Indirect costs included premature mortality and lost productivity. Results Direct health impacts for both conditions combined included 1454 ED presentations, 682 hospitalisations, 72446 general practice visits and 7122 specialist visits. Indirect health impacts included 13 deaths and between 483000 and 2.8 million days of lost productivity. Total costs ranged between A$126.5 million and A$436.7 million for asthma and between A$65.3 million and A$259.7 million for AR. Per-person annual costs ranged between A$1918 and A$6617 for asthma and between A$597 and A$2374 for AR. Conclusions The main financial burden due to asthma and AR was related to productivity losses from presenteeism and absenteeism. The magnitude of the economic impacts of AR and asthma warrants further analysis to produce a national-level assessment. Such analyses could identify cost-effective interventions that produce highest benefits for the management of these conditions in our community. What is known about the topic? Allergic respiratory diseases, and particularly asthma and AR, pose a significant health burden, with effects including asthma-related hospital admissions, significant pharmaceutical expenditure and lost workforce and school education productivity. Australia, and particularly Tasmania, has a high prevalence of these conditions, but no recent studies have appraised or estimated their health impacts and costs. What does this paper add? This paper proposes a unique and transparent costing model that allows the costs of these conditions to be estimated while accounting for restrictions in data availability. The model is used to provide the first comprehensive costings of asthma and AR in Tasmania, Australia. We identified that the estimated health costs are dominated by productivity losses from presenteeism and absenteeism, and that total per person costs are higher for a person with asthma compared to one with AR. What are the implications for practitioners? This analysis has the potential to guide cost-effective interventions by identifying where the highest benefits may be obtained when managing these conditions in our community.

Updating and validating quality prescribing indicators for use in Australian general practice.

This study aims to update and validate quality prescribing indicators (QPIs) for Australian general practice. The study comprised two phases: (1) developing preliminary potential QPIs based on the 2006 National Prescribing Service (NPS) MedicineWise indicators, published literature, international indicators and guidelines, and through qualitative focus group discussions; and (2) validating the proposed QPIs through a two-round online survey using the Delphi technique. The Delphi panel included four GPs, four pharmacists and two clinical pharmacologists. The Delphi panel rated the potential QPIs for their validity, importance and feasibility using a 1-10 Likert scale. In round one, all proposed QPIs presented as 'prescribing rules' achieved high scores regarding validity, importance and feasibility No rule was eliminated and three new rules were introduced. Rules were reworded into 'prescribing indicators' for round two, which resulted in 35 indicators being accepted and two indicators being eliminated. The final QPIs also include seven drug-drug interactions, which received high scores in round one. In conclusion, 42 QPIs were nominated for use in Australian general practice, based on their validity, importance and feasibility. If implemented, these QPIs have the potential to assist in efforts to improve the quality and safety of medicines management.

Gambling Behaviour, Problem Gambling and Reasons for Gambling Among International Students in Tasmania, Australia.

Individuals who undertake tertiary study outside their home countries ("international students") may be at increased risk of problem gambling behaviour. To inform this issue, we examined gambling behaviour, problem gambling behaviour and reasons for gambling among international students, primarily from Asian countries, attending university in Tasmania, Australia. Online surveys that included established measures of each outcome were completed by these students (n = 382) along with a comparison group of domestic students (n = 1013). While most forms of gambling assessed were less common among international students than among domestic students, rates of problem gambling were higher among international students (2.6%) than among domestic (1.4%) students. Further, whereas rates of problem gambling did not differ by sex among domestic students, problem gambling among international students was confined to males. Hence, rates of problem gambling were markedly elevated in this subgroup (5% of all male international students, 15% of male international students who reported any form of gambling in the past 12 months). International students were more likely than domestic students to report engaging in gambling as a means of regulating their internal states and for a challenge and these and other reasons for gambling were positively correlated with problem gambling behaviour. The findings support the need for population- and campus-based health promotion and early intervention programs targeting international students, male students in particular. Information concerning individuals' reasons for gambling might usefully be included in these programs.

Health and Well-Being of International University Students, and Comparison with Domestic Students, in Tasmania, Australia.

International students comprise an increasingly larger proportion of higher education students globally. Empirical evidence about the health and well-being of these students is, however, limited. We sought to examine the health and well-being of international students, primarily from Asian countries, attending the University of Tasmania, Australia, using domestic students as a comparison group. Ethics approval was given to invite (via email) all currently enrolled students to participate in the study by completing a pilot-tested, online survey. The survey was completed by 382 international students (response rate = 8.9%) and 1013 domestic students (9.2%). Independent samples t-tests, analysis of variance (ANOVA) and chi-square tests were used for bivariate comparisons between international and domestic students, and between subgroups of international students. Regression models were used to examine the associations between student status (international vs. domestic) and health outcomes, controlling for demographic and enrolment variables. International students, particularly male students, were found to be at increased risk of several adverse health outcomes while also being less likely to seek help for mental health and related problems. The findings indicate the need for accessible, targeted, culturally-sensitive health promotion and early intervention programs.

Early predictors of summative assessment performance in general practice post-graduate training: A retrospective cohort study.

BACKGROUND: Success in summative general practice (GP) training assessments is one indicator of competence for practice. Early-training factors predictive of outcomes would facilitate targeted interventions aimed at preventing candidate failures. METHODS: We undertook a retrospective cohort study of Australian GP trainees in two training organizations over five years. Associations of pre-training and early-training predictors with summative examination scores in an Applied Knowledge Test (AKT), Key Features Paper (KFP), and Objective Structured Clinical Examination (OSCE), plus failure on any one of these, were tested via univariate and multivariable regression. Predictors were program-entry selection-score decile, pre-training-commencement multiple choice assessment (MCQA), direct observation of practice performance, and clinical supervisor reports. RESULTS: On univariate analyses, selection decile and MCQA were associated with all outcomes except AKT. There were no associations of other predictors with any outcomes. On multivariable analysis, selection decile and MCQA performance were predictive of OSCE performance. MCQA performance was also predictive of KFP performance. On multivariable analysis, no predictors were associated with AKT performance or failing any examination. CONCLUSIONS: Selection decile and pre-commencement MCQA performance were predictive of performance in some summative assessments. These findings could inform selection policies and targeted early interventions for trainees at most risk for exam failure.

Prescribing of psychotropic medication for nursing home residents with dementia: a general practitioner survey.

OBJECTIVE: The aim of this study was to identify factors influencing the prescribing of psychotropic medication by general practitioners (GPs) to nursing home residents with dementia. SUBJECTS AND METHODS: GPs with experience in nursing homes were recruited through professional body newsletter advertising, while 1,000 randomly selected GPs from southeastern Australia were invited to participate, along with a targeted group of GPs in Tasmania. An anonymous survey was used to collect GPs' opinions. RESULTS: A lack of nursing staff and resources was cited as the major barrier to GPs recommending non-pharmacological techniques for behavioral and psychological symptoms of dementia (BPSD; cited by 55%; 78/141), and increasing staff levels at the nursing home ranked as the most important factor to reduce the usage of psychotropic agents (cited by 60%; 76/126). CONCLUSION: According to GPs, strategies to reduce the reliance on psychotropic medication by nursing home residents should be directed toward improved staffing and resources at the facilities.

Learning global health: a pilot study of an online collaborative intercultural peer group activity involving medical students in Australia and Indonesia.

BACKGROUND: There is limited research to inform effective pedagogies for teaching global health to undergraduate medical students. Theoretically, using a combination of teaching pedagogies typically used in 'international classrooms' may prove to be an effective way of learning global health. This pilot study aimed to explore the experiences of medical students in Australia and Indonesia who participated in a reciprocal intercultural participatory peer e-learning activity (RIPPLE) in global health. METHODS: Seventy-one third year medical students (49 from Australia and 22 from Indonesia) from the University of Tasmania (Australia) and the University of Nusa Cendana (Indonesia) participated in the RIPPLE activity. Participants were randomly distributed into 11 intercultural 'virtual' groups. The groups collaborated online over two weeks to study a global health topic of their choice, and each group produced a structured research abstract. Pre- and post-RIPPLE questionnaires were used to capture students' experiences of the activity. Descriptive quantitative data were analysed with Microsoft Excel and qualitative data were thematically analysed. RESULTS: Students' motivation to volunteer for this activity included: curiosity about the innovative approach to learning; wanting to expand knowledge of global health; hoping to build personal and professional relationships; and a desire to be part of an intercultural experience. Afer completing the RIPPLE program, participants reported on global health knowledge acquisition, the development of peer relationships, and insight into another culture. Barriers to achieving the learning outcomes associated with RIPPLE included problems with establishing consistent online communication, and effectively managing time to simultaneously complete RIPPLE and other curricula activities. CONCLUSIONS: Medical students from both countries found benefits in working together in small virtual groups to complement existing teaching in global health. However, our pilot study demonstrated that while intercultural collaborative peer learning activities like RIPPLE are feasible, they require robust logistical support and an awareness of the need to manage curriculum alignment in ways that facilitate more effective student engagement.

Early predictors of need for remediation in the Australian general practice training program: a retrospective cohort study.

Underperforming trainees requiring remediation may threaten patient safety and are challenging for vocational training programs. Decisions to institute remediation are high-stakes-remediation being resource-intensive and emotionally demanding on trainees. Detection of underperformance requiring remediation is particularly problematic in general (family) practice. We sought to establish early-training assessment instruments predictive of general practice (GP) trainees' subsequently requiring formal remediation. We conducted a retrospective cohort study of trainees from a large Australian regionally-based GP training organization. The outcome factor was requirement for formal remediation. Independent variables were demographic factors and a range of formative assessments conducted immediately prior to or during early-stage training. Analyses employed univariate and multivariate logistic regression of each predictor assessment modality with the outcome, adjusting for potential confounders. Of 248 trainees, 26 (10.5 %) required formal remediation. Performance on the Colleague Feedback Evaluation Tool (entailing feedback from a trainee's clinical colleagues on clinical performance, communication and probity) and External Clinical Teaching Visits (half-day sessions of the trainee's clinical consultations observed directly by an experienced GP), along with non-Australian primary medical qualification, were significantly associated with requiring remediation. There was a non-significant trend for association with performance on the Doctors Interpersonal Skills Questionnaire (patient feedback on interpersonal elements of the consultation). There were no significant associations with entry-selection scores or formative exam or assessment scores. Our finding that 'in vivo' assessments of complex behaviour, but not 'in vitro' knowledge-based assessments, predict need for remediation is consistent with theoretical understanding of the nature of remediation decision-making and should inform remediation practice in GP vocational training.

The effectiveness of student-run organizations within global health promotion initiatives.

INTRODUCTION: This commentary describes a student-led project that distributed long-lasting insecticide-treated nets in Masaka, Uganda. The role of student-led initiatives in global health promotion projects is also discussed. METHODS: A survey of 213 net recipients was conducted after a 12-month period to evaluate malaria prevention knowledge, and net use and maintenance. RESULTS: Only 4.7% of recipients could not recall any malaria prevention methods. Seventy percent of pregnant women and 86.5% of children under five slept under a net the previous night. Only two households (0.9%) no longer possessed a net, and nets were not used in 2.3% of houses. Household observation revealed 17.4% of nets had at least one problem that would compromise effectiveness. CONCLUSIONS: Student-led projects can play an important role in effectively preventing malaria. However coordination with existing programs, targeting hard-to-access groups, and training of students overcomes some common limitations of such student-led initiatives.

Retention of knowledge and perceived relevance of basic sciences in an integrated case-based learning (CBL) curriculum.

BACKGROUND: Knowledge and understanding of basic biomedical sciences remain essential to medical practice, particularly when faced with the continual advancement of diagnostic and therapeutic modalities. Evidence suggests, however, that retention tends to atrophy across the span of an average medical course and into the early postgraduate years, as preoccupation with clinical medicine predominates. We postulated that perceived relevance demonstrated through applicability to clinical situations may assist in retention of basic science knowledge. METHODS: To test this hypothesis in our own medical student cohort, we administered a paper-based 50 MCQ assessment to a sample of students from Years 2 through 5. Covariates pertaining to demographics, prior educational experience, and the perceived clinical relevance of each question were also collected. RESULTS: A total of 232 students (Years 2-5, response rate 50%) undertook the assessment task. This sample had comparable demographic and performance characteristics to the whole medical school cohort. In general, discipline-specific and overall scores were better for students in the latter years of the course compared to those in Year 2; male students and domestic students tended to perform better than their respective counterparts in certain disciplines. In the clinical years, perceived clinical relevance was significantly and positively correlated with item performance. CONCLUSIONS: This study suggests that perceived clinical relevance is a contributing factor to the retention of basic science knowledge and behoves curriculum planners to make clinical relevance a more explicit component of applied science teaching throughout the medical course.

Promoting clinical reasoning in general practice trainees: role of the clinical teacher.

BACKGROUND: Clinical reasoning requires knowledge, cognition and metacognition, and is contextually bound. Clinical teachers can and should play a key role in explicitly promoting clinical reasoning. CONTEXT: The aim of this article is to relate the clinical reasoning literature to the general practice or family medicine context, and to provide clinical teachers with strategies to promote clinical reasoning. INNOVATION: It is important that the clinical teacher teaches trainees the specific skills sets of the expert general practitioner (e.g. synthesising skills, recognising prototypes, focusing on cues and clues, using community resources and dealing with uncertainty) in order to promote clinical reasoning in the context of general practice or family medicine. Clinical teachers need to understand their own reasoning processes as well as be able to convey that knowledge to their trainees. They also need to understand the developmental stages of clinical reasoning and be able to nurture each trainee's own expertise. Strategies for facilitating effective clinical reasoning in trainees include adequate exposure to patients, offering the trainees opportunity for reflection and feedback, and coaching on the techniques of reasoning in the general practice context. IMPLICATIONS: The journey to expertise in clinical reasoning is unique to each clinician, with different skills developing at different rates, depending on content, context and past experience. Doctors enter into general practice training with the building blocks of biomedical and clinical knowledge and a desire to learn how to be a general practitioner. Clinical teachers are integral in the process of helping trainees learn how to 'think like a general practitioner'.

What are the perceived learning needs of Australian general practice registrars for quality prescribing?

BACKGROUND: Little is known about the perceived learning needs of Australian general practice (GP) registrars in relation to the quality use of medicines (QUM) or the difficulties experienced when learning to prescribe. This study aimed to address this gap. METHODS: GP registrars' perceived learning needs were investigated through an online national survey, interviews and focus groups. Medical educators' perceptions were canvassed in semi-structured interviews in order to gain a broader perspective of the registrars' needs. Qualitative data analysis was informed by a systematic framework method involving a number of stages. Survey data were analysed descriptively. RESULTS: The two most commonly attended QUM educational activities took place in the workplace and through regional training providers. Outside of these structured educational activities, registrars learned to prescribe mainly through social and situated means. Difficulties encountered by GP registrars included the transition from hospital prescribing to prescribing in the GP context, judging how well they were prescribing and identifying appropriate and efficient sources of information at the point of care. CONCLUSIONS: GP registrars learn to prescribe primarily and opportunistically in the workplace. Despite many resources being expended on the provision of guidelines, decision-support systems and training, GP registrars expressed difficulties related to QUM. Ways of easing the transition into GP and of managing the information 'overload' related to medicines (and prescribing) in an evidence-guided, efficient and timely manner are needed. GP registrars should be provided with explicit feedback about the process and outcomes of prescribing decisions, including the use of audits, in order to improve their ability to judge their own prescribing.

Development of the special skills post in expedition medicine for general practice registrars in Australia.

Wilderness, mountain, and expedition medicine training for physicians is now well developed in North America and Europe. This paper describes the development and content of the first such program in Australia. The Special Skills Post in Expedition Medicine is a 6-month post, developed by General Practice Training Tasmania, that is integrated into general practice training and combines clinical placements in travel medicine, general practice, emergency medicine, a self-guided workbook covering core and elective topics, and an 8-day field trip.
