Stability of pemetrexed disodium in sodium chloride 0.9% w/v intravenous Viaflo infusion bags.

OBJECTIVES: The aim of this study was to assess the stability of pemetrexed disodium (Alimta), reconstituted in 100 mL sodium chloride 0.9% w/v intravenous infusion bags (Baxter Viaflo) at two target bag concentrations (2.0 and 13.5 mg/mL) during storage at 2-8°C for 28 days (protected from light), followed by 24 hours at 25±2°C with 60±5% relative humidity (RH) (protected from light). This study was commissioned by NHS England and NHS Improvement to generate data to aid shelf life extensions for aseptic products compounded in National Health Service (NHS) hospital aseptic facilities. METHODS: A high performance liquid chromatography (HPLC) assay was developed and validated to monitor pemetrexed concentration and related substance levels in accordance with NHS yellow cover document requirements. This assay and analysis of related substances was used alongside visual inspection, pH monitoring and sub-visible particle count analysis to monitor stability. The stability of three preparations of each concentration of pemetrexed disodium in Viaflo saline bags (0.9% w/v) was assessed at various time points. RESULTS: Pemetrexed assay concentrations remained >97.0% of initial concentration at all points during the study (including the period at elevated temperature). Appearance remained consistent with the Summary of Product Characteristics, particle count data remained within the British Pharmacopoeia limits, and pH remained within 0.43 units of T=0 at all times. The increases in related substance levels during the study were found to be the limiting factor for shelf life assignment. CONCLUSION: The data for appearance, pH, sub-visible particle count analysis and pemetrexed assay would support a shelf life of 28 days stored at 2-8°C (protected from light) followed by 24 hours at 25±2°C with 60±5% RH (protected from light). However, given the increase in related substance levels, a shelf life of 21 days stored at 2-8°C (protected from light) was deemed to be appropriate.

Large-scale calibration and simulation of COVID-19 epidemiologic scenarios to support healthcare planning.

The COVID-19 pandemic has provided stiff challenges for planning and resourcing in health services in the UK and worldwide. Epidemiological models can provide simulations of how infectious disease might progress in a population given certain parameters. We adapted an agent-based model of COVID-19 to inform planning and decision-making within a healthcare setting, and created a software framework that automates processes for calibrating the model parameters to health data and allows the model to be run at national population scale on National Health Service (NHS) infrastructure. We developed a method for calibrating the model to three daily data streams (hospital admissions, intensive care occupancy, and deaths), and demonstrate that on cross-validation the model fits acceptably to unseen data streams including official estimates of COVID-19 incidence. Once calibrated, we use the model to simulate future scenarios of the spread of COVID-19 in England and show that the simulations provide useful projections of future COVID-19 clinical demand. These simulations were used to support operational planning in the NHS in England, and we present the example of the use of these simulations in projecting future clinical demand during the rollout of the national COVID-19 vaccination programme. Being able to investigate uncertainty and test sensitivities was particularly important to the operational planning team. This epidemiological model operates within an ecosystem of data technologies, drawing on a range of NHS, government and academic data sources, and provides results to strategists, planners and downstream data systems. We discuss the data resources that enabled this work and the data challenges that were faced.

A scoping review protocol of age-friendly practices during the COVID-19 pandemic.

Background: Actions focused on age-friendly environments contribute to promote and maintain older people's functional ability and may enable them to contribute to their communities and enjoy life. As such, age-friendly practices require collaboration between diverse stakeholders across multiple sectors responsible for natural, built, and social environments, which can be particularly relevant during public health emergencies when socio-ecological vulnerabilities become more salient and may disproportionally affect older people. This paper presents a protocol for a scoping review aiming to investigate the breadth of evidence concerning the development, implementation, and evaluation of age-friendly practices during the COVID-19 pandemic. The protocol sets out the objectives, methods, and dissemination plans for the review. Methods: The scoping review will be conducted in line with the Joanna Briggs Institute (JBI) scoping review methodology. We will search databases (PubMed, Web of Science, Embase, CINAHL, Scopus, PsychNet) and grey literature sources. Publications relating to practices across the 8 domains of the World Health Organization's age-friendly cities and communities' framework will be included. A tabular data extraction tool will be used to facilitate a narrative synthesis of results. Ethics and dissemination: Ethical approval is not required as the methods proposed for this scoping review consist of collecting publicly available data. Findings will be reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for Scoping Reviews (PRISMA-ScR) and submitted to a journal for academic dissemination. Lay dissemination plans include an infographic and a blog-style article presenting our core results. Conclusion: The publication of this protocol allows for transparency in the systematic process of a scoping review focused on age-friendly practices during COVID-19. Findings emerging from the scoping review will provide insights into the evidence available regarding age-friendly activities during COVID-19 and may inform future age-friendly practices during public health emergencies and beyond.

Verbatim Theater: Prompting Reflection and Discussion about Healthcare Culture as a Means of Promoting Culture Change.

Problem: The mistreatment of medical and nursing students and junior health professionals has been reported internationally in research and the media. Mistreatment can be embedded and normalized in hierarchical healthcare workplaces, limiting the effectiveness of policies and reporting tools to generate change; as a result, some of those who experience mistreatment later perpetuate it. We used a novel, creative approach, verbatim theater, to highlight the complexity of healthcare workplaces, encourage critical reflection, and support long-term culture change. Intervention: Verbatim theater is a theater-for-change documentary genre in which a playscript is devised using only the words spoken by informants. In 2017, 30 healthcare students and health professionals were recruited and interviewed about their experience of work and training by the multidisciplinary Sydney Arts and Health Collective using semi-structured interviews. Interview transcripts became the primary material from which the script for the verbatim theater play 'Grace Under Pressure' was developed. The performing arts have previously been used to develop the communication skills of health professional students; this esthetic expression of the real-life effects of healthcare workplace culture on trainees and students was implemented to stimulate consciousness of, and dialogue about, workplace mistreatment in healthcare work and training. Context: The play premiered at a major Sydney theater in October 2017, attended by the lay public and student and practicing health professionals. In November 2017, three focus groups were held with a sample of audience members comprising healthcare professionals and students. These focus groups explored the impact of the play on reflection and discussion of healthcare culture and/or promoting culture change in the health workplace. We analyzed the focus group data using theoretical thematic analysis, informed by Turner's theory of the relation between 'social' and 'esthetic' drama to understand the impact of the play on its audience. Impact: Focus group members recognized aspects of their personal experience of professionalism, training, and workplace culture in the play, Grace Under Pressure. They reported that the play's use of real-life stories and authentic language facilitated their critical reflection. Participants constructed some learning as 'revelation,' in which the play enabled them to gain significant new insight into the culture of health care and opened up discussions with colleagues. As a result, participants suggested possible remedies for unhealthy aspects of the culture, including systemic issues of bullying and harassment. A small number of participants critiqued aspects of the play they believed did not adequately reflect their experience, with some believing that the play over-emphasized workplace mistreatment. Lessons Learned: Verbatim theater is a potent method for making personal experiences of healthcare workplace and training culture more visible to lay and health professional audiences. In line with Turner's theory, the play's use of real-life stories and authentic language enabled recognition of systemic challenges in healthcare workplaces by training and practicing health professionals in the audience. Verbatim theater provides a means to promote awareness and discussion of difficult social issues and potential means of addressing them.

Grace Under Pressure: a drama-based approach to tackling mistreatment of medical students.

A positive and respectful learning environment is fundamental to the development of professional identities in healthcare. Yet medical students report poor behaviour from healthcare professionals that contradict professionalism teaching. An interdisciplinary group designed and implemented a drama-based workshop series, based on applied theatre techniques, to help students develop positive professional qualities and interpersonal skills to deal with challenges in the healthcare setting. We piloted the workshops at the University of Sydney in 2015. Attendees completed evaluation questionnaires and participated in a focus group or interview. Of 30 workshop attendances, there were 29 completed questionnaires and three participants attended a focus group or interview. Workshop activities were rated as 'very good' or 'good' by 21/22 (95.5%). Thematic analysis of qualitative data highlighted the rationale for participation (to deal with bullying, prevent becoming a bully, learn social skills), workshop benefits (express emotions, learn about status dynamics and deconstructing personalities, empathy, fun), challenges (meeting participants' expectations, participants' need for further practice) and implications for medical education (need to develop awareness of others' perspectives). Our research has shown that there is momentum to challenge mistreatment in medical education. While a multipronged approach is needed to generate systemic change, this pilot offers a positive and creative innovation. It helps students improve their interpersonal skills and sense of self to deal with challenges in the healthcare setting, including mistreatment.

Reactions to Diversity: Using Theater to Teach Medical Students about Cultural Diversity.

Training medical students to understand the effects of culture and marginalization on health outcomes is important to the future health of increasingly diverse populations. We devised and evaluated a short training module on working with diversity to challenge students' thinking about the role of both patient and practitioner culture in health outcomes. The workshop combined didactic teaching about culture as a social determinant of health using the cultural humility model, interactive exercises, and applied theater techniques. We evaluated changes in the students' perceptions and attitudes over time using the Reaction to Diversity Inventory. There was initial significant improvement. Women and students with no past diversity training responded best. However, scores largely reverted to baseline over 12 months.
