    Background: The demands on medical and healthcare practitioners are continuously changing, with new technologies, treatments and regulatory guidelines emerging each year. One such example is increased focus on the impact of medical error, which although difficult to measure is generally acknowledged to be responsible for significant numbers of patient harms each year. As a consequence, the provision of education and training must adapt to reflect this, providing learners with an updated range of skills that can meet the needs of their profession. An increase in the use of technology has been one way that educators have sought to achieve this, along with developing pedagogies and approaches such as problem-based learning which better reflect the challenges faced by medicine and healthcare professionals. Virtual patients are interactive simulations of clinical scenarios that have been shown to be well-suited to the development of clinical reasoning skills. They have been widely used in medicine and healthcare training, although they have yet to be fully adopted across the sector. Virtual patients can vary significantly in their design and their use within activities. To date there is a lack of knowledge about the ways different design features of virtual patients can be optimally applied to benefit student learning. Aim: The aim of this thesis is to increase knowledge of how virtual patient design impacts upon undergraduate medical student learning, particularly when targeting medical error education in small-group teaching. Methods: The four studies in this thesis explore design features of virtual patients and how they impact upon different aspects of the student learning experience. Study I investigated the impact of including video elements within a virtual patient used to support a problem-based learning tutorial. Mixed methods were used to capture aspects of both student and tutor experiences, and a thematic analysis was undertaken to identify themes in the unstructured responses. Studies II-IV each explored different outcomes around the use of decision-making elements in virtual patients designed to develop awareness of medical errors. A series of six virtual patients were delivered to undergraduate medical students undertaking paediatric placements across six institutions as part of small-group teaching. Students were allocated to one of two virtual patient designs: a branched design that allowed students to make decisions, or a linear design which followed a pre-determined structure without scope for student decision-making. In study II, following the completion of all virtual patients, students completed a survey instrument designed to measure aspects of their motivation and learning strategies. Comparisons between the branched and linear groups were made to establish the impact of the virtual patient design. Study III used log-linear analysis to explore learner performance in a single-best answer assessment and included an additional group of students who received traditional lecture-based teaching. In the assessment, questions were categorised in one of 3 groups; directly related to decision points in the virtual patient cases, in the same area of management but relating to different decisions and options, and in the same broad area of medicine but different areas of patient management. Study IV compared the self-efficacy and other related factors between students who received the branched and linear virtual patients, and asked participants to complete a survey instrument directly after each virtual patient case. A regression analysis was performed to explore how different factors impacted upon the self-efficacy of students. Results: In study I we identified eight distinct themes relating to the use of video elements. One theme related to levels of engagement, with some participants finding the use of video to be beneficial and others preferring text. Some participants identified that the use of video slowed the pace of the tutorial but was well suited to providing information about procedures. In study II we demonstrated that the use of linear or branched structures for virtual patients had no consistent impact upon the measures of learner motivation and learning strategies. Similarly, in study IV our findings showed that the use of a linear or branched design did not impact upon learner self-efficacy. However, in study III we showed that both virtual patient design and institution had an impact on student learning, and these were retained in our final model. A branching design for virtual patients improved student learning around the decision points in the virtual patient cases. Students performed equally well in the questions regarding the same management approaches but different decisions regardless of whether they received the linear or branched interventions, and scored higher than those that received traditional teaching. There was no difference between any of the groups in the questions that related to different areas of patient management. Conclusions: Overall, our findings suggest that the use of a branched virtual patient design is able to improve student learning around medical error when used in small-group teaching, and is not associated with any impact on learner motivation or self-efficacy. Our studies have not provided any evidence that this learning transfers to other areas of medicine. These findings have been broadly repeated at six institutions, demonstrating that despite evidence of the strong impact of institutional culture on our results, the findings can be generalised to multiple settings. We conclude that educators should seek to design virtual patients which allow learners to rehearse key patient management decisions, supported by video in areas where this can be most beneficial, such as demonstrating procedures. These virtual patients should be embedded in broader learning activities that encourage learners to identify deeper features within the learning, with a view to transferring that learning to other areas of patient management

    BACKGROUND: Psychoeducation delivered face-to-face is effective in alleviating mental health morbidities in family carers of individuals with psychosis. However, research in such interventions delivered online is scarce. We evaluated the effectiveness of a digital multicomponent intervention-COPe-support-in improving carers' mental wellbeing and caregiving-related outcomes. METHODS: In this two-arm, individually randomised, superiority trial, people aged 18 years or older who provided at least weekly support in any format for a relative or close friend affected by psychosis across England were randomly assigned (1:1) to either COPe-support or a passive online information resource using an independent online system. Participants were recruited through 30 mental health UK National Health Service trusts. The study team were masked to allocation and assessment of outcomes as all data collection took place online. Participants had access to either condition for 40 weeks and were advised to spend at least half an hour per week over the initial 20 weeks to go through materials at their own pace and to allow time to integrate knowledge and skills learned into practice. It was not feasible to mask participants or the online facilitator to intervention allocation. COPe-support provided psychoeducation on psychosis-related caregiving strategies and forums with professionals and other carers, and the control intervention comprised a passive online information resource. The primary outcome at 20 weeks was mental wellbeing measured by the Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS; minimally clinically important difference [MCID] 3). This trial is registered with ISRCTN, 89563420. FINDINGS: Between March 1, 2018, and Feb 14, 2020, 407 participants were randomly assigned, with 204 allocated to COPe-support and 203 allocated to control. The participants (mean age 53·1 years, SD 13·2) were mostly female (330 [81%] of 407 participants) and White (359 [88%] of 407 participants). 346 (85%) of 407 participants provided primary endpoint data, 174 (85%) of 204 participants in the COPe-support group and 172 (85%) of 203 participants in the control group. The mean WEMWBS score at 20 weeks was 44·5 (SD 8·31) for the COPe-support group and 43·3 (9·19) for the control group. We found no evidence of a difference in wellbeing between the two groups (adjusted mean difference 0·37, 95% CI -1·14 to 1·88; p=0·63). In the COPe-support group, 106 (52%) of 204 participants met the complier definition of a minimum of two logins in separate weeks. The complier average causal effect analysis increased the difference in WEMWBS scores (adjusted difference 0·83, 95% CI -1·45 to 3·11; p=0·47), but this was lower than the MCID. There were no adverse events. INTERPRETATION: Our findings did not support the use of COPe-support over a passive online information resource. However, further research to optimise digital interventions adjunctive to face-to-face support for carers remains important. FUNDING: National Institute for Health Research

    BACKGROUND: Virtual patients are interactive digital simulations of clinical scenarios for the purpose of health professions education. There is no current collated evidence on the effectiveness of this form of education. OBJECTIVE: The goal of this study was to evaluate the effectiveness of virtual patients compared with traditional education, blended with traditional education, compared with other types of digital education, and design variants of virtual patients in health professions education. The outcomes of interest were knowledge, skills, attitudes, and satisfaction. METHODS: We performed a systematic review on the effectiveness of virtual patient simulations in pre- and postregistration health professions education following Cochrane methodology. We searched 7 databases from the year 1990 up to September 2018. No language restrictions were applied. We included randomized controlled trials and cluster randomized trials. We independently selected studies, extracted data, and assessed risk of bias and then compared the information in pairs. We contacted study authors for additional information if necessary. All pooled analyses were based on random-effects models. RESULTS: A total of 51 trials involving 4696 participants met our inclusion criteria. Furthermore, 25 studies compared virtual patients with traditional education, 11 studies investigated virtual patients as blended learning, 5 studies compared virtual patients with different forms of digital education, and 10 studies compared different design variants. The pooled analysis of studies comparing the effect of virtual patients to traditional education showed similar results for knowledge (standardized mean difference [SMD]=0.11, 95% CI -0.17 to 0.39, I2=74%, n=927) and favored virtual patients for skills (SMD=0.90, 95% CI 0.49 to 1.32, I2=88%, n=897). Studies measuring attitudes and satisfaction predominantly used surveys with item-by-item comparison. Trials comparing virtual patients with different forms of digital education and design variants were not numerous enough to give clear recommendations. Several methodological limitations in the included studies and heterogeneity contributed to a generally low quality of evidence. CONCLUSIONS: Low to modest and mixed evidence suggests that when compared with traditional education, virtual patients can more effectively improve skills, and at least as effectively improve knowledge. The skills that improved were clinical reasoning, procedural skills, and a mix of procedural and team skills. We found evidence of effectiveness in both high-income and low- and middle-income countries, demonstrating the global applicability of virtual patients. Further research should explore the utility of different design variants of virtual patients

    PURPOSE: As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19-free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS: This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19-free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS: Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19-free surgical pathways. Patients who underwent surgery within COVID-19-free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19-free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score-matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19-free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION: Within available resources, dedicated COVID-19-free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks

    The environmental impacts of palm oil in context

    Get PDF
    Delivering the Sustainable Development Goals (SDGs) requires balancing demands on land between agriculture (SDG 2) and biodiversity (SDG 15). The production of vegetable oils, and in particular palm oil, illustrates these competing demands and trade-offs. Palm oil accounts for 40% of the current global annual demand for vegetable oil as food, animal feed, and fuel (210 million tons (Mt)), but planted oil palm covers less than 5-5.5% of total global oil crop area (ca. 425 Mha), due to oil palm’s relatively high yields5. Recent oil palm expansion in forested regions of Borneo, Sumatra, and the Malay Peninsula, where >90% of global palm oil is produced, has led to substantial concern around oil palm’s role in deforestation. Oil palm expansion’s direct contribution to regional tropical deforestation varies widely, ranging from 3% in West Africa to 47% in Malaysia. Oil palm is also implicated in peatland draining and burning in Southeast Asia. Documented negative environmental impacts from such expansion include biodiversity declines, greenhouse gas emissions, and air pollution. However, oil palm generally produces more oil per area than other oil crops, is often economically viable in sites unsuitable for most other crops, and generates considerable wealth for at least some actors. Global demand for vegetable oils is projected to increase by 46% by 20509. Meeting this demand through additional expansion of oil palm versus other vegetable oil crops will lead to substantial differential effects on biodiversity, food security, climate change, land degradation, and livelihoods. Our review highlights that, although substantial gaps remain in our understanding of the relationship between the environmental, socio-cultural and economic impacts of oil palm, and the scope, stringency and effectiveness of initiatives to address these, there has been little research into the impacts and trade-offs of other vegetable oil crops. 65 Greater research attention needs to be given to investigating the impacts of palm oil production 66 compared to alternatives for the trade-offs to be assessed at a global scale
