Background In the evolving healthcare landscape of the United Arab Emirates (UAE), establishing cost-effectiveness thresholds (CETs) is pivotal to informing decision-makers about the value of health technologies. Objective This study aimed to establish CETs for the UAE that harmonise with international standards while reflecting the nation’s unique healthcare needs and economic context. Setting United Arab Emirates. Methods A multitiered methodology was employed, involving a literature review, a panel of national experts and workshops with key stakeholders, including healthcare providers, government health departments and healthcare payers. The panel and workshops were integral in assessing global CET practices and their applicability to the UAE providing a preliminary framework for CET in the UAE. Structured voting sessions were then conducted allowing voting on crucial aspects of CET to determine the baseline threshold, multipliers for severity, rarity and health gain, and methodologies for quantifying disease severity. Results CETs were linked to the economic status of the UAE, with a baseline threshold of 0.75 times the gross domestic product per capita for one quality-adjusted life year gained. A multiplier system was introduced to reflect societal views on disease severity, disease rarity and the relative health benefit of health technologies. Based on the voting results, disease rarity was deemed the most crucial factor, receiving a maximum multiplier of 3X, while severity and health gain were assigned a maximum of 2X. The multiplier values for both disease severity and relative health gain would be determined on a continuous scale. The proportional or relative shortfall method would be used to assess disease severity. Conclusions The proposed CET framework for the UAE will be dependent on local generation of cost-effectiveness evidence. Periodic review of CETs based on initial experiences ensures the responsiveness of policymakers to the changing healthcare and economic environment.

Background: Pneumonia is a significant cause of morbidity and mortality among adults globally. This retrospective cohort analysis assessed the pneumonia burden and related healthcare resource utilization and costs in the at-risk (low, medium, and high-risk) adult patients in Dubai, United Arab Emirates (UAE). Methods: The claims data from January 1, 2014 to June 30, 2019 were extracted from the Dubai Real-World Claims Database for patients, aged ≥18 year, having at least 1 pneumonia claim. Data for the inpatient, outpatient and emergency visits were assessed for 12-months, before (pre-index) and after (follow-up) a pneumonia episode. Healthcare costs were calculated based on dollar value of 2020. Results: Total 48,562 records of eligible patients were analyzed (mean age = 39.9 years; low [62.1%], medium [36.2%] and high [1.7%] risk cohorts). Mean all-cause healthcare costs were approximately >45% higher in the follow-up period (1,947 USD/patient) versus pre-index period (1,327 USD/patient). During follow-up period, the mean annual pneumonia incidence rate was 1.3 episodes, with a similar pattern across all cohorts. Overall, mean claims and costs (USD) per patient (all-cause) were highest in the high-risk cohort in the follow-up period (claims: overall, 11.6; high-risk, 22.0; medium-risk, 13.9; low-risk, 9.9; costs: high-risk, 14,184; medium-risk, 2,240; low-risk, 1,388). Similarly, the mean pneumonia-related costs (USD) per patient were highest for the high-risk cohort (overall: 1,305; high-risk, 10,207; medium-risk, 1,283; low-risk, 882), however, the claims were similar across cohorts (claims/patient: overall: 2.0; high-risk, 1.9; medium-risk, 2.2; low-risk, 1.9). Most all-cause and pneumonia-related costs were due to inpatient visits (4,901 and 4,818 USD respectively), while outpatient (1,232 and 166 USD respectively) and emergency visits (347 and 206 USD respectively) contributed significantly lesser. Conclusions: Pneumonia imposes a significant healthcare burden in the UAE, especially in the high-risk patients with severe comorbidities. These findings would guide clinicians and policy makers to make informed decisions.

Background Though biologic agents have significantly improved the treatment of inflammatory arthritis (rheumatoid arthritis, psoriatic arthritis, and axial spondyloarthritis), high costs, stringent regulations, strict reimbursement criteria, and existing patents have limited patient access to treatments. While being highly similar in quality, safety, and efficacy to biologic reference products, biosimilars can reduce the financial burden and prevent underutilization of medication. Objective The objective of this initiative was to develop an evidence-based consensus of overarching principles and recommendations aimed at standardizing the use of biosimilars in treating inflammatory arthritis in the Gulf region. Methods A task force of practicing rheumatologists, a clinical pharmacist, a health economist, patients, regulators, and payors from across the Gulf region developed recommendations and overarching principles based on the outputs of a systematic literature review conducted to address Patient-Intervention-Comparison-Outcome (PICO) questions specific to key challenges regarding the use of biosimilars for the treatment of inflammatory arthritis in the region. As the data before 2017 have been previously reviewed in another publication, the current review focused on data published between January 2017 and August 2022 (PROSPERO ID CRD42022364002). Consensus on each statement required a level of agreement of 70% or greater. Results Consensus was reached for five overarching principles and nine recommendations by the task force. The principles emphasize the importance of improving the awareness, understanding, and perception of biosimilars, as well as the need for regulated regional real-world data generation and protocols to make biosimilars a viable and affordable treatment option for all patients. The consensus recommendations advocate the need for shared treatment decisions between rheumatologists and patients when considering biosimilars. They further recommend that confirmation of a biosimilar’s efficacy and safety in a single indication is sufficient for extrapolation to other diseases for which the reference product has been approved. Finally, there is a need for pharmacovigilance and national health policies governing the adoption and prescription of biosimilars in clinical practice across the region. Conclusions These are the first consensus recommendations for the Gulf region based on a systematic literature review and Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines, integrating clinical evidence with clinical expertise to optimize decision making for the use of biosimilars in patients with inflammatory arthritis. They were formulated based on predominantly international data because of the limited regional data and therefore can be generalized to serve as recommendations for healthcare professionals in other parts of the world.

Objective: This paper aims to develop a biosimilar value framework with local stakeholders in Gulf Cooperation Council (GCC) countries. Methods: A convenience sample of ten key opinion leaders from the United Arab Emirates, Kingdom of Saudi Arabia, Kuwait, Oman and Qatar participated in an expert panel meeting in November 2022 that examined factors positively influencing biosimilar adoption in these countries. The discussion was structured around a conceptual biosimilar value framework and an overview of biosimilar policies as derived from a targeted review of the peer-reviewed and grey literature. Results: The expert panel agreed on a biosimilar value framework for the GCC countries that is founded on trust, cost savings and contextual considerations. They emphasized the importance of launching educational initiatives that build trust in and expand knowledge of all stakeholders about biosimilars. This also includes making stakeholders aware of the various value propositions of biosimilars as an instrument to produce, for example, cost savings. Finally, they stressed that biosimilar adoption is influenced by contextual factors such as incentives and implementation efforts. Conclusion: Our proposed biosimilars value framekwork is the first set of recommendations in the Arab countries designed to help policymakers and decision-makers promote biosimilar adoption, both in high-income GCC countries and in low- and middle-income countries.

Influenza is often considered a trivial illness due to its generally mild symptoms. This perception overlooks the extensive scale of people affected annually, many of whom experience severe complications requiring hospitalization. To date, vaccination remains the most effective strategy to reduce the burden of influenza. This study assesses the cost-effectiveness of influenza vaccination within the United Arab Emirates and Iraq from the payer perspective, highlighting its potential to improve public health outcomes. A static individual simulation decision tree model was employed over a lifetime horizon to simulate two scenarios: one with influenza vaccination and one without. The model includes individual characteristics such as age, sex, chronic health conditions, and specific risk groups to determine the infection rate. Based on such factors, if a patient gets infected, their journey can range from outpatient care to ICU admission and even death in severe cases. Vaccination was found to be cost-effective for the general population in the UAE, while in Iraq, it was dominant. In high-risk patients, vaccination showed dominance in all age groups, while in non-high-risk patients, dominance was shown in 0-4 years and 65+ years age groups. Additionally, the vaccine demonstrated cost-effectiveness for the general population in all scenario analyses and even showed dominance with the reduced rate of ICU admission, in-hospital death, and varying infection rates in Iraq. By conducting a thorough analysis of the vaccine's cost-effectiveness, policymakers are provided with valuable local insights enabling more effective vaccination strategies in their respective countries.

Hemophilia A management in the United Arab Emirates (UAE) is still largely driven by treatment acquisition costs. This may limit access to innovative therapies such as emicizumab despite their broader clinical value. This paper aimed to identify barriers to value-based reimbursement and develop policy recommendations to strengthen health technology assessment (HTA) for hemophilia A in the UAE. An evidence-informed multi-stakeholder roundtable was held during the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) UAE Chapter 2026 Conference. The discussion was informed by published evidence, regional clinical guidance, and expert perspectives. The roundtable discussion was transcribed and summarized using descriptive qualitative analysis, and the manuscript synthesizes the main policy themes identified by the participants. Four priority areas emerged: adopting value-based assessment beyond acquisition cost, strengthening the use of evidence in reimbursement decisions, establishing national hemophilia registries with standardized data collection, and improving timely access to innovative therapies for high-risk patients. Overall, participants agreed that stronger HTA processes and better evidence generation are needed to support reimbursement decisions. Implementing these recommendations could improve access to innovative therapies and support more consistent, patient-centered, and sustainable hemophilia care in the UAE.
