Characterising the spatial dynamics of sympatric Aedes Aegypti and Aedes Albopictus populations in the Philippines
Entomological surveillance and control are essential to the management of dengue fever (DF). Hence, understanding the spatial and temporal patterns of DF vectors, Aedes (Stegomyia) aegypti (L.) and Ae. (Stegomyia) albopictus (Skuse), is paramount. In th
The use of Real World Evidence in the European context: An analysis of key expert opinion
Randomised controlled trials (RCT), traditionally seen as the gold standard in drug approval requirement terms, are becoming more difficult due to, among other reasons, budget constraints, increasing complexities and the shrinking of patient populations. Real world evidence (RWE), data used for decision making that is not derived from traditional RCT, may in future play an increasing role in market access and reimbursement decisions. This paper analyses key pricing and reimbursement stakeholders’ opinions of RWE across five European countries via a focus group-style discussion. Areas probed included regulatory implications and the role of RWE in the study countries, RWE processes and implementation on decision making, meaningful outcomes from RWE and priorities for future focus and industry support. Results showed that RWE was used to some extent in all countries, generally in accelerated access and re-review situations, with accepted endpoints including overall survival, morbidity, avoidable mortality and quality of life among others, but that there were a number of areas where improvement was necessary if RWE use was to become more common place
RWE in Europe Paper II: The use of Real World Evidence in the disease context
Real World Evidence (RWE), the use of data not collected via traditional randomised controlled trials (RCT) for decision-making, is becoming more interesting to market-access and reimbursement decision-makers, despite potential methodological issues around its use. This paper, the second in a series looking at the use of Real World Evidence (RWE) in Europe, analyses the opinions of a number of key experts in pricing and reimbursement from a selection of countries across Europe. Discussion centred on the use of RWE in licensing, commissioning, clinical decision-making and patient and outcome related decision-making in the context of three different treatment areas – chronic disease, oncology and rare diseases. Results of discussion sessions with ‘RWE experts’ indicated that the associated benefits of RWE are becoming more relevant but there is a need for a well-organised, high quality system for data generation, interpretation and use. It is likely that different treatment areas will have differing RWE requirements and differing levels of utility. In the rare disease arena, RWE may have a role in licensing based decisions, but this is unlikely for chronic disease or oncology. In order to enhance the role of RWE, and to ensure it meets its full potential in all treatment areas, a multi-stakeholder approach at the EU level is required, with collaboration between national and supranational organisations and all stakeholders including patient organisations, manufacturers and reimbursement agencies
The factors affecting household transmission dynamics and community compliance with Ebola control measures: a mixed-methods study in a rural village in Sierra Leone.
BACKGROUND: Little is understood of Ebola virus disease (EVD) transmission dynamics and community compliance with control measures over time. Understanding these interactions is essential if interventions are to be effective in future outbreaks. We conducted a mixed-methods study to explore these factors in a rural village that experienced sustained EVD transmission in Kailahun District, Sierra Leone. METHODS: We reconstructed transmission dynamics using a cross-sectional survey conducted in April 2015, and cross-referenced our results with surveillance, burial, and Ebola Management Centre (EMC) data. Factors associated with EVD transmission were assessed with Cox proportional hazards regression. Following the survey, qualitative semi-structured interviews explored views of community informants and households. RESULTS: All households (n = 240; 1161 individuals) participated in the survey. 29 of 31 EVD probable/confirmed cases died (93·5% case fatality rate); six deaths (20·6%) had been missed by other surveillance systems. Transmission over five generations lasted 16 weeks. Although most households had ≤5 members there was a significant increase in risk of Ebola in households with > 5 members. Risk of EVD was also associated with older age. Cases were spatially clustered; all occurred in 15 households. EVD transmission was better understood when the community experience started to concord with public health messages being given. Perceptions of contact tracing changed from invading privacy and selling people to ensuring community safety. Burials in plastic bags, without female attendants or prayer, were perceived as dishonourable. Further reasons for low compliance were low EMC survival rates, family perceptions of a moral duty to provide care to relatives, poor communication with the EMC, and loss of livelihoods due to quarantine. Compliance with response measures increased only after the second generation, coinciding with the implementation of restrictive by-laws, return of the first survivor, reduced contact with dead bodies, and admission of patients to the EMC. CONCLUSIONS: Transmission occurred primarily in a few large households, with prolonged transmission and a high death toll. Return of a survivor to the village and more effective implementation of control strategies coincided with increased compliance to control measures, with few subsequent cases. We propose key recommendations for management of EVD outbreaks based on this experience
RWE in Europe Paper III: A Roadmap for RWE
Real world evidence (RWE) has been touted as a remedy for current market access issues, facilitating quicker approvals and increased odds of reimbursement at a good price. It is therefore an attractive avenue for pursuit for manufacturers today. This paper, the third in a series looking at the use of RWE in Europe, outlines the discussions held between key opinion leaders in pricing and reimbursement across a number of European countries at a roundtable-style meeting. The aim of the meeting was to develop a 3-year roadmap, and resulting action plan, of initiatives for the enhanced use of RWE in decision-making in the pharmaceutical industry. Following a series of brainstorming sessions across the areas of commissioning and access, clinical evidence and patients and outcomes, contributors were asked to prioritise the importance of a refined set of initiatives identified in these brainstorming sessions to develop the three-year road map. Finally, four key points from the roadmap were identified for initial action: actively engage in early dialogue with payers on RWE needs; consensus exercise on RWD/E in clinical decisions, develop a definition of patient reported/relevant outcomes and develop a model approach for the collection of patient reported/relevant outcomes data. These action points are seen as the most imperative steps for enhancing the role of RWE. If its use is to become more common addressing these steps, as quickly and efficiently as possible, will be vital for all stakeholders in the pharmaceutical arena

RWE in Europe Paper IV: Engaging pharma in the RWE Roadmap
This paper summarises discussions held at the fourth round-table style meeting with a group of expert stakeholders with experience in specialist disease areas and commissioning of care plus prior experience in the field of real world evidence (RWE). The aim of these meetings was to gain an understanding of the use of RWE across Europe and to develop a road map of initiatives for the pharmaceutical industry in order to enhance their use of RWE. This, the fourth and final paper in this series, outlines the future potential of the stakeholder group involved in the project to date
