BackgroundSymptoms of systemic lupus erythematosus (SLE) vary between patients, but those of increased disease activity typically include musculoskeletal and mucocutaneous manifestations such as joint pain, swelling, and rashes. Several treatment options are available to patients with SLE with variable efficacy. Many treatments, especially corticosteroids, cause unwanted side effects, although little is currently known about patients’ preferences for treatments of SLE.ObjectiveWe aimed to identify which attributes of SLE treatment are valued by patients and to quantify their relative importance.MethodsAdult participants with moderate-to-severe SLE were asked to make a series of choices between two hypothetical treatments in an online discrete choice experiment (DCE). A latent class model (LCL) was estimated to analyze choice data. Relative attribute importance (RAI) was calculated to determine the …

The WHO recommends that all affected countries work toward the elimination of malaria, even those still experiencing a high burden of disease. However, malaria programs in the final phase of elimination or those working to prevent re-establishment of transmission after elimination could benefit from specific evidence-based recommendations for these settings as part of comprehensive and quality-controlled malaria guidelines. The WHO convened an external guideline development group to formulate recommendations for interventions to reduce or prevent malaria transmission in areas with very low–to low-transmission levels and those that have eliminated malaria. In addition, several interventions that could be deployed in higher burden areas to accelerate elimination, such as mass drug administration, were reviewed. Systematic reviews were conducted that synthesized and evaluated evidence for the benefits …

Interest in using patient preference (PP) data alongside traditional economic models in health technology assessment (HTA) is growing, including using PP data to quantify non-health benefits. However, this is limited by a lack of standardised methods. In this article, we describe a method for using discrete choice experiment (DCE) data to estimate the value of non-health benefits in terms of quality-adjusted survival equivalence (QASE), which is consistent with the concept of value prevalent among HTA agencies. We describe how PP data can be used to estimate QASE, assess the ability to test the face-validity of QASE estimates of changes in mode of administration calculated from five published DCE oncology studies and review the methodological and normative considerations associated with using QASE to support HTA. We conclude that QASE may have some methodological advantages over alternative …

IntroductionInformation about patient preferences for the treatment of anaemia associated with chronic kidney disease (CKD) is scarce. Hence, our aim was to examine how patients with non-dialysis-dependent CKD valued attributes of alternative hypothetical anaemia treatments.MethodsA discrete choice experiment (DCE) was conducted in adult patients who reported a clinical diagnosis of CKD-related anaemia. Treatment attributes included mode and frequency of administration, need for iron supplementation, risk of gastrointestinal side effects, risk of major cardiovascular events and impact on energy levels (as defined by the vitality section of the SF-6D health index). Logit models were used to analyse patients’ preferences.ResultsThe DCE was completed by 200 patients in four countries. Patients preferred an oral mode of administration. Patients were willing to tolerate a 5.1% (95% CI 2.0–8.3%) increase in …

ObjectivesEngagement with decision-makers is crucial to the development of decision tools in health technology assessment. This study applied a continual stakeholder engagement approach to develop an open-source multi-criteria decision analysis (MCDA) to support decision-making in major depressive disorder (MDD) by diverse stakeholders in the US.MethodsThe MCDA was developed based on the 8-step process in ISPOR Good Practices Reports. We convened a twenty-member advisory group (AG) consisting of representatives from patient, clinician, employer, payer, manufacturer, and researcher perspectives throughout the process to ensure the module can effectively address real-world decision needs. Facilitated discussions were conducted to define decision problems, prioritize criteria, and identify performance metrics for different criteria. Three MCDA experts provided guidance to identify the best …

Background The Coronavirus disease 2019 (COVID-19) pandemic caused significantly lower reported mortalities on the African continent as compared to other regions. Yet, many countries on the continent are still contending with the devastating economic, social and indirect health impacts. African researchers and policy makers have identified research priority areas which take cognisance of the unique research needs of African countries. A baseline assessment of the alignment of funded research in Africa to these priorities and World Health Organization’s COVID-19 research priorities was undertaken in July, 2020. We present a two-year update to this analysis of funded COVID-19 research in Africa. Methods Data captured in the UK Collaborative on Development Research and Global Research Collaboration for Infectious Disease Preparedness COVID-19 Research Project Tracker as of 15th July, 2022 was analysed. An additional analysis of institutions receiving funding for COVID-19 research is presented. We also analysed the change in funding for COVID-19 research in Africa since July, 2020. Results The limited COVID-19 research identified in Africa early in the pandemic has persisted over the subsequent two-year period assessed. When number of projects are considered, governmental funders based in Europe and United States supported the most research. Only nine research funders based in Africa were identified. A number of partnerships between African institutions and institutions based on other continents were identified, however, most research projects were undertaken in research institutions based in Africa only. Our …

We describe the MalariaGEN Pf7 data resource, the seventh release of Plasmodium falciparum genome variation data from the MalariaGEN network. It comprises over 20,000 samples from 82 partner studies in 33 countries, including several malaria endemic regions that were previously underrepresented. For the first time we include dried blood spot samples that were sequenced after selective whole genome amplification, necessitating new methods to genotype copy number variations. We identify a large number of newly emerging crt mutations in parts of Southeast Asia, and show examples of heterogeneities in patterns of drug resistance within Africa and within the Indian subcontinent. We describe the profile of variations in the C-terminal of the csp gene and relate this to the sequence used in the RTS, S and R21 malaria vaccines. Pf7 provides high-quality data on genotype calls for 6 million SNPs and short …

Objective: Blood pressure control is a challenge for patients for reasons including adherence, medication side effects, poor access to healthcare, and inconvenience of long-term treatment. Renal denervation is a treatment option that lowers blood pressure in combination with lifestyle modifications and medications, but it requires a minimally invasive procedure. This study assessed how patients make choices between treatments, and quantified their willingness to undergo renal denervation. Methods: An online discrete choice experiment (DCE) was completed by US adults with uncontrolled hypertension despite being prescribed ≥1 medication. In 10 DCE tasks, participants chose between two hypothetical treatments defined by the 10-year cardiovascular (CV) risk, current treatments (procedure/number of pills per day), durability/need for future treatments (additional procedure or pills), and risks of mild-to …
