Comparison of health technology assessment for new medicines in France and England : an example based on ixazomib for patients with relapsed or refractory multiple myeloma
Introduction: The appraisal of medicines is often a complex and iterative process. We compared the health technology assessment (HTA) process in England and France taking as a case study the example of ixazomib for multiple myeloma.
Methods: We undertook an analysis of eight relevant published documents identifed from the websites of the French and English HTA bodies (HAS and NICE, respectively). We analyse patients’ availability of ixazomib resulting in the different stages of the appraisal process.
Results: We identified differences in the assessment, one of these being the use of an appraisal scope in England allowing the differentiation of populations and comparators according to previously approved treatments. Ixazomib became available earlier in France as part of an early access programme, but the availability was soon discontinued for newly eligible patients following an HAS determination that Ixazomib yielded no additional benefit. This opinion resulted in long pricing discussions. In England, despite the absence of an early access programme and following a process that included cost-effectiveness evaluation combined with pricing discussions, the medicine was fairly rapidly recommended for use.
Conclusions: Differences in the HTA process may result in appreciable differences in time from marketing authorisation to health service adoption of newly licensed drug

Calibrated interdental brushing for the prevention of periodontal pathogens infection in young adults - a randomized controlled clinical trial
Periodontal disease is clearly correlated with systemic disease. The presence of periodontal pathogens
in interdental spaces in young, healthy adults is a strong indicator of the need to introduce daily
interdental prophylaxis. Twenty-five subjects (aged 18–35 years), diagnosticated clinically as
periodontally healthy, were enrolled in this study. One hundred interdental sites were included. Among
these sites, 50 “test” sites were cleaned daily with calibrated interdental brushes (IDBs), whereas the
other 50 sites were not cleaned and considered “controls”. The interdental biofilm at these interdental
sites was collected at the beginning of the study (basal) and at 1 week, 2 weeks, 3 weeks, 4 weeks,
and 3 months. Real-time polymerase chain reaction (PCR) methodology was used to quantify (i)
19 periodontal bacteria, including Porphyromonas gingivalis, Treponema denticola, and Tannerella
forsythia, and (ii) total bacteria. In the test sites, the quantity of total bacteria decreased over time with
the use of IDBs. The bacteria from the red and orange Socransky complexes, which are associated with
periodontal disease, significantly decreased in the test sites but not in the control sites. Bacteria from
the yellow, and purple Socransky complexes, which are associated with periodontal health, increased
significantly in both groups whereas bacteria from the blue Socransky complex increased significantly
only in the test sites. Furthermore, at basal, 66% of test sites and 68% of control sites bled during
interdental brushing. These percentages decreased by 85% in 3 months for the test sites and by 27%
in the control sites. In conclusion, the daily use of calibrated IDBs can reduce periodontal pathogens,
reestablish symbiotic microbiota and, decrease interdental inflammation in interdental sites of healthy
young adults
Exploring the Determinants of Polypharmacy Prescribing and Dispensing Behaviours in Primary Care for the Elderly-Protocol for a Qualitative Study
Polypharmacy is becoming increasingly common, especially among the elderly. It often has a negative connotation, but is sometimes necessary or even desirable, and needed to categorize polypharmacy as appropriate or inappropriate. The challenge is in ensuring that this is considered appropriate when necessary. We aimed to develop an evidence-based intervention to reduce the risks associated with using a systematic approach, involving key stakeholders in prescribing and dispensing drugs to the elderly in primary care. The purpose of this study is to identify the key components which are perceived as influencing these behaviours. It is a qualitative study of general practitioners (GPS) and community pharmacists involved in the care of the elderly. The main inclusion criterion is the geographic location. Qualitative data will be generated from one-on-one, semi-structured interviews and processed for thematic content analysis. Our approach integrates the patient pathway in primary care. It considers the fact that GP and pharmacist behaviours are far from being independent. This study represents the first step in the process of developing an intervention theory which involves a crossover between data from the literature and the knowledge of experts, allowing us to interrogate hypotheses about the influences and mechanisms associated with prescribing and dispensing drugs to the elderly in primary care
Int J Environ Res Public Health
Alcohol, a psychoactive substance with addictive potential, has major consequences on the population and public health. In France, alcohol use disorder affects approximately 3.5 million people, and 41,000 persons died in 2015. Alcohol consumption is significantly correlated to the workplace. Thus, the workplace is an area of opportunity to change risky behaviors and must play a key role in the prevention of alcohol misuse. To do this, it is essential to understand the consumption framework and to identify specific environmental risk factors. This qualitative study aims to describe the framework of alcohol consumption in the French public service. A focus group will be organized in France from November to January 2023. The participants will be: (i) representatives of the Local Health Insurance; (ii) over 18 years old; (iii) active or retired civil servants; (iv) mutualist activists; and (v) representatives of the Union of Health Prevention for the Obligatory System of the Public Service. The exclusion criteria for the study will be: (i) lack of consent form; (ii) inability to participate in the focus group, and (iii) early departure during the focus group. The focus groups will be supervised by two researchers following an interview guide. The data will be analyzed using the methodological framework, which consists in carrying out a thematic analysis. This will allow for an understanding of the sources of usage behaviors, and the identification of the most appropriate intervention functions for suitable prevention actions in order to reduce the risk of a transition to alcohol use disorder
Chemotherapeutic errors in hospitalised cancer patients: attributable damage and extra costs
<p>Abstract</p> <p>Background</p> <p>In spite of increasing efforts to enhance patient safety, medication errors in hospitalised patients are still relatively common, but with potentially severe consequences. This study aimed to assess antineoplastic medication errors in both affected patients and intercepted cases in terms of frequency, severity for patients, and costs.</p> <p>Methods</p> <p>A 1-year prospective study was conducted in order to identify the medication errors that occurred during chemotherapy treatment of cancer patients at a French university hospital. The severity and potential consequences of intercepted errors were independently assessed by two physicians. A cost analysis was performed using a simulation of potential hospital stays, with estimations based on the costs of diagnosis-related groups.</p> <p>Results</p> <p>Among the 6, 607 antineoplastic prescriptions, 341 (5.2%) contained at least one error, corresponding to a total of 449 medication errors. However, most errors (n = 436) were intercepted before medication was administered to the patients. Prescription errors represented 91% of errors, followed by pharmaceutical (8%) and administration errors (1%). According to an independent estimation, 13.4% of avoided errors would have resulted in temporary injury and 2.6% in permanent damage, while 2.6% would have compromised the vital prognosis of the patient, with four to eight deaths thus being avoided. Overall, 13 medication errors reached the patient without causing damage, although two patients required enhanced monitoring. If the intercepted errors had not been discovered, they would have resulted in 216 additional days of hospitalisation and cost an estimated annual total of 92, 907€, comprising 69, 248€ (74%) in hospital stays and 23, 658€ (26%) in additional drugs.</p> <p>Conclusion</p> <p>Our findings point to the very small number of chemotherapy errors that actually reach patients, although problems in the chemotherapy ordering process are frequent, with the potential for being dangerous and costly.</p
A year of genomic surveillance reveals how the SARS-CoV-2 pandemic unfolded in Africa.
The progression of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic in Africa has so far been heterogeneous, and the full impact is not yet well understood. In this study, we describe the genomic epidemiology using a dataset of 8746 genomes from 33 African countries and two overseas territories. We show that the epidemics in most countries were initiated by importations predominantly from Europe, which diminished after the early introduction of international travel restrictions. As the pandemic progressed, ongoing transmission in many countries and increasing mobility led to the emergence and spread within the continent of many variants of concern and interest, such as B.1.351, B.1.525, A.23.1, and C.1.1. Although distorted by low sampling numbers and blind spots, the findings highlight that Africa must not be left behind in the global pandemic response, otherwise it could become a source for new variants
The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance.
Investment in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing in Africa over the past year has led to a major increase in the number of sequences that have been generated and used to track the pandemic on the continent, a number that now exceeds 100,000 genomes. Our results show an increase in the number of African countries that are able to sequence domestically and highlight that local sequencing enables faster turnaround times and more-regular routine surveillance. Despite limitations of low testing proportions, findings from this genomic surveillance study underscore the heterogeneous nature of the pandemic and illuminate the distinct dispersal dynamics of variants of concern-particularly Alpha, Beta, Delta, and Omicron-on the continent. Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve while the continent faces many emerging and reemerging infectious disease threats. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century
Socializing One Health: an innovative strategy to investigate social and behavioral risks of emerging viral threats
In an effort to strengthen global capacity to prevent, detect, and control infectious diseases in animals and people, the United States Agency for International Development’s (USAID) Emerging Pandemic Threats (EPT) PREDICT project funded development of regional, national, and local One Health capacities for early disease detection, rapid response, disease control, and risk reduction. From the outset, the EPT approach was inclusive of social science research methods designed to understand the contexts and behaviors of communities living and working at human-animal-environment interfaces considered high-risk for virus emergence. Using qualitative and quantitative approaches, PREDICT behavioral research aimed to identify and assess a range of socio-cultural behaviors that could be influential in zoonotic disease emergence, amplification, and transmission. This broad approach to behavioral risk characterization enabled us to identify and characterize human activities that could be linked to the transmission dynamics of new and emerging viruses. This paper provides a discussion of implementation of a social science approach within a zoonotic surveillance framework. We conducted in-depth ethnographic interviews and focus groups to better understand the individual- and community-level knowledge, attitudes, and practices that potentially put participants at risk for zoonotic disease transmission from the animals they live and work with, across 6 interface domains. When we asked highly-exposed individuals (ie. bushmeat hunters, wildlife or guano farmers) about the risk they perceived in their occupational activities, most did not perceive it to be risky, whether because it was normalized by years (or generations) of doing such an activity, or due to lack of information about potential risks. Integrating the social sciences allows investigations of the specific human activities that are hypothesized to drive disease emergence, amplification, and transmission, in order to better substantiate behavioral disease drivers, along with the social dimensions of infection and transmission dynamics. Understanding these dynamics is critical to achieving health security--the protection from threats to health-- which requires investments in both collective and individual health security. Involving behavioral sciences into zoonotic disease surveillance allowed us to push toward fuller community integration and engagement and toward dialogue and implementation of recommendations for disease prevention and improved health security
The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance
INTRODUCTION
Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic.
RATIONALE
We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs).
RESULTS
Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants.
CONCLUSION
Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century
