Real-world service costs for neovascular-AMD clinics in the United Kingdom: structured literature review and scenario analysis. Curr Med Res Opin 2024; 40:1221-1233. [PMID: 38814914 DOI: 10.1080/03007995.2024.2362278] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2024] [Accepted: 05/28/2024] [Indexed: 06/01/2024]
Abstract
OBJECTIVE Current cost-effectiveness analyses (CEA) emphasize drug costs as the differentiator between NICE recommended anti-VEGF treatments but may neglect real-world non-drug costs of running nAMD services in the UK. To address this, this study identified real-world non-drug service cost items relevant to UK NHS nAMD clinics, including costs arising from operational strain (demand exceeding capacity). METHODS Cost items were identified by a structured literature review of peer-reviewed and grey literature, and an expert panel of 10 UK-based ophthalmologists with relevance to real-world practice. These items underwent meta-synthesis and were then determined in a consensus exercise. RESULTS Of 237 cost items identified, 217 (91.6%) met the consensus threshold of >0.51 and were included in the nAMD Service Non-Drug Cost Instrument (nAS). Sensitivity of cost items taken from UK Health Technology Assessment (HTA) using the nAS as the reference standard was low (HTAmin: 1.84%, 95% CI 0.50-4.65%; HTAmax: 70.51%, 95% CI 63.96-76.49%). False negative rates showed variable likelihood of misclassifying a service by cost burden depending on prevalence. Scenario analysis using cost magnitudes estimated annual per-patient clinic cost at £845 (within capacity) to £13,960 (under strain) compared to an HTAmin estimate of £210. Accounting for cost of strain under an assumed 50% increase in health resource utilization influenced cost-effectiveness in a hypothetical genericisation scenario. CONCLUSION Findings suggested that HTA underestimates UK NHS nAMD clinic cost burden with cost of strain contributing substantial additional unmeasured expense with impact on CEA. Given potential undertreatment due to strain, durability is suggested as one of the relevant factors in CEA of nAMD anti-VEGF treatments due to robustness under limited capacity conditions affecting UK ophthalmology services.

Chatterjee A, Ambrose K, Canaday DH, Delair S, Ezike N, Huber VC, Jhaveri R, Nyquist AC, Sporer A, Varman M, Vivekanandan R, Wojcik R, Jandhyala R. The association between influenza vaccine effectiveness and egg-based manufacturing technology: literature review and US expert consensus. Curr Med Res Opin 2024; 40:335-343. [PMID: 38054898 DOI: 10.1080/03007995.2023.2284386] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Accepted: 11/13/2023] [Indexed: 12/07/2023]
Abstract
BACKGROUND Influenza is associated with significant disease burden in the US and is currently best controlled by vaccination programs. Influenza vaccine effectiveness (VE) is low and may be reduced by several factors, including egg adaptations. Although non-egg-based influenza vaccines reportedly have greater VE in egg-adapted seasons, evidence for egg adaptations' reduction of VE is indirect and dissociated, apart from two previous European consensuses. METHODS This study replicated the methodology used in a 2020 literature review and European consensus, providing an updated review and consensus opinion of 10 US experts on the evidence for a mechanistic basis for reduction of VE due to egg-based manufacturing methods. A mechanistic basis was assumed if sufficient evidence was found for underlying principles proposed to give rise to such an effect. Evidence for each principle was brought forward from the 2020 review and identified here by structured literature review and expert panel. Experts rated the strength of support for each principle and a mechanistic basis for reduction of VE due to egg-based influenza vaccine manufacture in a consensus method (consensus for strong/very strong evidence = ≥ 3.5 on 5-point Likert scale). RESULTS Experts assessed 251 references (from previous study: 185; this study: 66). The majority of references for all underlying principles were rated as strong or very strong supporting evidence (52-86%). Global surveillance, WHO candidate vaccine virus selection, and manufacturing stages involving eggs were identified as most likely to impact influenza VE. CONCLUSION After review of extensive evidence for reduction of VE due to egg-based influenza vaccine manufacture, influenza experts in the US joined those in Europe in unanimous agreement for a mechanistic basis for the effect. Vaccine providers and administrators should consider use of non-egg-based influenza vaccine manufacture to reduce the risk of egg adaptations and likely impact on VE.

Abstract
BACKGROUND Priority setting in health research has been described as essential due to disparities within and between countries and populations. Commercial benefits to the pharmaceutical industry may increase the generation and use of regulatory Real-World Evidence which has recently been reported in the literature. Research must be steered by valuable priorities. This study's objective is to identify key gaps in the knowledge of triglyceride-induced acute pancreatitis by generating a list of potential research priorities for a Hypertriglyceridemia Patient Registry. METHOD The Jandhyala Method was used to observe the consensus of expert opinion from ten specialist clinicians in the treatment of triglyceride-induced acute pancreatitis across the US and EU. RESULTS Ten participants completed the consensus round of the Jandhyala method and generated 38 unique items which they all agreed with. The items were included in the generation of research priorities for a hypertriglyceridemia patient registry and presented a novel application of the Jandhyala method for the development of research questions, in aid of the validation of a core dataset. CONCLUSION The TG-IAP core dataset and research priorities combined can develop a globally harmonized framework where TG-IAP patients can be observed simultaneously using the same set of indicators. This will increase knowledge of the disease and facilitate higher-quality research by addressing issues related to incomplete data sets in observational studies. Furthermore, validation of new tools will be enabled, and diagnosis and monitoring will be improved as well as the detection of changes in disease severity and subsequent disease progression, improving the management of patients with TG-IAP overall. This will inform personalized patient management plans and improve patient outcomes along with their quality of life.

Jandhyala R. Development of a definition for real-world evidence using the Jandhyala method for observing consensus opinion among medical affairs pharmaceutical physicians. Curr Med Res Opin 2023; 39:1551-1558.

Abstract
OBJECTIVE Low rates of inclusion of real-world evidence (RWE) during regulation may arise from lack of clarity and consensus on its definition. A conceptually mature definition of RWE may have pragmatic utility, increasing its inclusion during regulation. The aim was to develop a definition of RWE to promote inclusion in regulatory submissions and assess its conceptual maturity. METHODS Thirteen medical affairs pharmaceutical physicians completed two qualitative online surveys to generate items needed in a definition of RWE. Items that reached a consensus index of > 50% (CI > = 0.51) were retained in the final definition. The maturity of the definition was assessed using concept analysis. RESULTS After attrition, 11 participants completed the study and generated 18 items to be included in a definition of RWE. All items reached the consensus threshold and were included. The definition was conceptually mature on three of the four dimensions: the potential for a consensual definition across stakeholders, a description of its characteristics and clear preconditions and outcomes. Further research is needed to delineate the boundaries of RWE. CONCLUSIONS A definition of RWE was generated that may increase its inclusion during medicines regulation, especially with further refinement from regulators and other stakeholders.

A protocol for an international, multicenter, prospective, non-interventional observational registry for patients with hypertriglyceridemia. Curr Med Res Opin 2023; 39:1663-1670. [PMID: 37665595 DOI: 10.1080/03007995.2023.2255129] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 08/18/2023] [Accepted: 08/31/2023] [Indexed: 09/05/2023]
Abstract
BACKGROUND In the study on triglyceride-induced pancreatitis (TG-IAP), a core clinical dataset using the Jandhyala method was developed to collect the minimum amount of information for each patient presenting with TG-IAP globally. This approach offered a unified framework for observing multiple populations of TG-IAP patients using the same set of indicators, resulting in a considerably larger and uniform real-world population. It was understood that when this core dataset is implemented in a patient registry it could address the issue of missing data in observational studies and produce higher-quality research. In this paper, the protocol used to design and implement a patient registry for this core dataset to generate real-world evidence from multiple sites is described. METHOD The study is designed as an international, multicenter, non-interventional, observational registry that will enroll adult patients with hypertriglyceridemia to collect natural history data on the treatment, progression, and long-term outcomes of hypertriglyceridemia-induced acute pancreatitis. Patients with both hypertriglyceridemia and pancreatitis will be invited to participate in the registry at participating hospitals and centers worldwide. DISCUSSION Data from this registry, and others like it, is intended for healthcare providers to optimize clinical decision-making through an enhanced understanding of the variability, progression, and natural history of hypertriglyceridemia as well as the burden of disease. CONCLUSION Global epidemiological data on hypertriglyceridemia and its role in acute pancreatitis is limited. Using real-world evidence, this registry, along with others like it, may help healthcare providers understand the variability, progression, natural history, and burden of the disease, and improve the diagnosis and management of HTG and TG-IAP.
