Abstract: High-quality research into education costs can inform better decision making. Improvements to cost research can be guided by information about the research questions, methods and reporting of studies evaluating costs in health professions education (HPE). Our objective was to appraise the overall state of the field and evaluate temporal trends in the methods and reporting quality of cost evaluations in HPE research. We searched the MEDLINE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), EMBASE, Business Source Complete and ERIC (Education Resources Information Centre) databases on 31 July 2017. To evaluate trends over time, we s led research reports at 5-year intervals (2001, 2006, 2011 and 2016). All original research studies in HPE that reported a cost outcome were included. The Medical Education Research Study Quality Instrument (MERSQI) and the BMJ economic checklist were used to appraise methodological and reporting quality, respectively. Trends in quality over time were analysed. A total of 78 studies were included, of which 16 were published in 2001, 15 in 2006, 20 in 2011 and 27 in 2016. The region most commonly represented was the USA (n = 43). The profession most commonly referred to was that of the physician (n = 46). The mean ± standard deviation (SD) MERSQI score was 10.9 ± 2.6 out of 18, with no significant change over time (p = 0.55). The mean ± SD BMJ score was 13.5 ± 7.1 out of 35, with no significant change over time (p = 0.39). A total of 49 (63%) studies stated a cost-related research question, 23 (29%) stated the type of cost evaluation used, and 31 (40%) described the method of estimating resource quantities and unit costs. A total of 16 studies compared two or more interventions and reported both cost and learning outcomes. The absolute number of cost evaluations in HPE is increasing. However, there are shortcomings in the quality of methodology and reporting, and these are not improving over time.

Abstract: Cost studies are increasingly popular given resource constraints. While scholars stress the context‐dependent nature of cost, and the importance of theory, cost studies remain context‐blind and atheoretical. However, realist economic evaluation (REE) privileges context and the testing/refinement of economic programme theory. This preliminary REE serves to test and refine economic programme theory for supervision training programmes of different durations to better inform future programme design/implementation. Our preliminary REE unpacked how short (half‐day) and extended (12 week) supervision training programmes in Victoria, Australia, produced costs and outcomes. We employed mixed methods: qualitative realist and quantitative cost methods. Economically optimised programme models were developed guided by identified cost‐sensitive mechanisms and contexts. As part of identified context‐mechanism‐outcome configurations (CMOCs) for both training programmes, we found a wider ersity of positive outcomes but greater costs for the extended programme (11 outcomes AU$3069/learner) compared with the short programme (7 outcomes $385/learner). We identified four shared cost‐sensitive mechanisms for both programmes (training duration, learner protected time, learner engagement, and facilitator competence) and one shared cost‐sensitive context (learners' supervisory experience). We developed two economically optimised programme models: (1) short programme for experienced supervisors facilitated by senior educators ($406/learner) and (2) extended programme for inexperienced supervisors facilitated by junior educators ($2104/learner). Our initial economic programme theory was somewhat supported, refuted and refined. Results were partly consistent with previous research, but also extended it through unpacking cost‐sensitive mechanisms and contexts. Although our preliminary REE fills a pressing gap in the methodology literature, conducting REE was challenging given our desire to integrate economic and realist analyses fully, and remain faithful to realist principles. Attention to training duration and experience levels of the facilitator–learner dyad may help to balance the cost and outcomes of training programmes.

Abstract: The use of the coordinated silver (I) complex based on solvate ionic liquid in epoxy resins is reported to enable unprecedented electrical and thermomechanical properties. The novel hybrid material is aligned at the molecular level using an electric field, demonstrating high electrical conductivity, excellent energy storage properties, and rapid curing behavior. The electric‐field treated epoxy resin system shows a maximum electric conductivity of 2.05 × 10 5 S m −1 , 20 folds of the same untreated system, and 3 folds of the same treated system but with 5.0% silver nanoparticles. Furthermore, this system shows an ultrafast curing rate of around 500 s at a temperature of 42.0 °C and reveals excellent energy storage achieving an average capacitance of 27.5 F g −1 at a scan rate of 1.0 mV s −1 . Quantum mechanics is applied and the synchrotron beamline is utilized to optimize and investigate the properties of the system, opening the door to the next generation of thermoset polymers with multifunctional properties.

Abstract: The power of computational modeling and simulation for establishing clear links between materials’ intrinsic properties and their atomic structure has more and more increased the demand for reliable and reproducible protocols. Despite this increased demand, no one approach can provide reliable and reproducible outcomes to predict the properties of novel materials, particularly rapidly cured epoxy-resins with additives. This study introduces the first computational modeling and simulation protocol for crosslinking rapidly cured epoxy resin thermosets based on solvate ionic liquid (SIL). The protocol combines several modeling approaches, including quantum mechanics (QMs) and molecular dynamics (MDs). Furthermore, it insightfully provides a wide range of thermo-mechanical, chemical, and mechano-chemical properties, which agree with experimental data.

Abstract: The radical‐bearing epoxy monomer could be the ideal embodiment of multifunctionality in epoxy‐based materials. This study demonstrates the potential of macroradical epoxies as surface coating materials. A diepoxide monomer derivatized with a stable nitroxide radical is polymerized with a diamine hardener under the influence of a magnetic field. The magnetically oriented and stable radicals in the polymer backbone render the coatings antimicrobial. The unconventional use of magnets during polymerization proved crucial in correlating the structure‐property relationships with antimicrobial performance inferred from oscillatory rheological technique, polarized macro‐attenuated total reflectance – infrared (macro‐ATR‐IR) spectroscopy and X‐ray photoelectron spectroscopy (XPS). The magnetic thermal curing influenced the surface morphology, resulting in a synergy of the coating's radical nature with microbiostatic performance assessed using the Kirby‐Bauer test and liquid chromatography – mass spectroscopy (LC–MS). Further, the magnetic curing of blends with a traditional epoxy monomer demonstrates that radical alignment is more critical than radical density in imparting biocidal behavior. This study shows how the systematic use of magnets during polymerization could pave for probing more significant insights into the mechanism of antimicrobial action in radical‐bearing polymers.

Abstract: Advancements in materials science and fabrication techniques have contributed to the significant growing attention to a wide variety of sensors for digital healthcare. While the progress in this area is tremendously impressive, few wearable sensors with the capability of real-time blood pressure monitoring are approved for clinical use. One of the key obstacles in the further development of wearable sensors for medical applications is the lack of comprehensive technical evaluation of sensor materials against the expected clinical performance. Here, we present an extensive review and critical analysis of various materials applied in the design and fabrication of wearable sensors. In our unique transdisciplinary approach, we studied the fundamentals of blood pressure and examined its measuring modalities while focusing on their clinical use and sensing principles to identify material functionalities. Then, we carefully reviewed various categories of functional materials utilized in sensor building blocks allowing for comparative analysis of the performance of a wide range of materials throughout the sensor operational-life cycle. Not only this provides essential data to enhance the materials’ properties and optimize their performance, but also, it highlights new perspectives and provides suggestions to develop the next generation pressure sensors for clinical use.

Abstract: Introduction We sought to evaluate the reporting and methodological quality of cost evaluations of physician continuing professional development (CPD). Methods We conducted a systematic review, searching MEDLINE, Embase, PsycInfo, and the Cochrane Database for studies comparing the cost of physician CPD (last update 23 April 2020). Two reviewers, working independently, screened all articles for inclusion. Two reviewers extracted information on reporting quality using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS), and on methodological quality using the Medical Education Research Study Quality Instrument (MERSQI) and a published reference case. Results Of 3338 potentially eligible studies, 62 were included. Operational definitions of methodological and reporting quality elements were iteratively revised. Articles reported mean (SD) 43% (20%) of CHEERS elements for the Title/Abstract, 56% (34%) for Introduction, 66% (19%) for Methods, 61% (17%) for Results, and 66% (30%) for Discussion, with overall reporting index 292 (83) (maximum 500). Valuation methods were reported infrequently (resource selection 10 of 62 [16%], resource quantitation 10 [16%], pricing 26 [42%]), as were descriptions/discussion of the physicians trained (42 [68%]), training setting (42 [68%]), training intervention (40 [65%]), sensitivity analyses of uncertainty (9 [15%]), and generalizability (30 [48%]). MERSQI scores ranged from 6.0 to 16.0 (mean 11.2 [2.4]). Changes over time in reporting index (initial 241 [105], final 321 [52]) and MERSQI scores (initial 9.8 [2.7], final 11.9 [1.9]) were not statistically significant (p ≥ 0.08).

Abstract: Introduction: There are few dedicated health professions education research centres in Australia and New Zealand. As a result, researchers, especially novices, can often feel isolated. In this discussion paper, we introduce The Canberra Meeting—an initiative for building research capacity in health professions education by developing a community of practice through an annual meeting. In this meeting, novice researchers present on significant problems or questions arising from their research, known as a dilemma presentation, and facilitate discussion with an audience of peer PhD students, earlycareer researchers and senior researchers. The meeting aims to provide an opportunity to expand professional networks, exchange ideas and build knowledge.Innovation: A half-day pilot meeting was held in Canberra prior to the 2019 ANZAHPE conference. The meeting was designed for, and planned by, novice researchers. There were 37 attendees, including 13 who self-identified as novice researchers. Three half-hour dilemma sessions were held, comprised of 10 minutes of presentation time followed by 20 minutes of discussion.Evaluation and outcomes: Feedback on the pilot was sought through prompted group discussions. The following guiding principles were developed, including that the initiative should be 1) inclusive to all health professions and seek to reach isolated researchers 2) accessible, by providing equal opportunity of access 3) constructive, such that participants feel safe to present and engage in discussions and 4) sustainable, such that the community of practice continues despite changes in in idual membership.What’s next: Planning is currently underway for a meeting prior to the next ANZAHPE conference. The event will be publicly advertised.

Abstract: This article was migrated. The article was marked as recommended. Introduction The following represents proceedings of an online roundtable workshop on high value and low-cost virtual reality healthcare professional education. The purpose of the workshop was to seek the views of professionals from different sectors and different countries on moving toward high value and low-cost virtual reality education. The workshop was comprised of eight delegates with an interest in this subject. The delegates were from Europe, the Middle East, and Australia. They represented different sectors - including clinical medicine, educational economics, health professional education, simulation, technology, evidence-based methodologies, and industry.ThemesThe following themes emerged from the workshop: the challenge of thinking about the cost of virtual reality from the points of view of the payer and the user the core need to define the context of use of virtual reality the absolute need to define the purpose of a virtual reality programme the recognition of the growing opportunity of multiplayer virtual reality the need to exploit the unique properties of virtual reality the importance of realising that there are already various forms of virtual reality available and these can achieve different outcomes at different costs the need to integrate virtual reality into the rest of the curriculum and the various forms of cost analysis that might be suitable for evaluating the cost and outcomes of virtual reality. ConclusionsIn the long-term, a growing body of evidence that is based on original research and systematic reviews will help us decide what is high value and low-cost virtual reality in healthcare professional education. However, a strategic approach is needed to ensure that the original research concentrates on the right topics that will yield the most value to education decision-makers and to other related stakeholders. We feel that non-hierarchical interdisciplinary roundtable discussions are an effective means of planning strategy.
