Although collaboration is an intensive way of working together, it is essential for such efforts to achieve shared goals. Health technology assessment (HTA) is transdisciplinary and has an important history of collaboration, with collaboration featuring increasingly in the strategic plans of HTA bodies and stakeholders. Collaboration can be between HTA bodies and between HTA bodies and other stakeholders-most notably regulators but increasingly payers, patient and caregiver organizations, clinicians-clinical societies, and academia.

Operationalization guidance is needed to support health technology assessment (HTA) bodies considering implementing lifecycle HTA (LC-HTA) approaches. The 2022 Health Technology Assessment International (HTAi) Global Policy Forum (GPF) established a Task Force to develop a position paper on LC-HTA. In its first paper, the Task Force established a definition and framework for LC-HTA in order to tailor it to specific decision problems.

Objectives: Economic evaluations of vaccination may not fully account for nonhealth patient impacts on families, communities, and society (ie, broader value elements). Omission of broader value elements may reflect a lack of established measurement methodology, lack of agreement over which value elements to include in economic evaluations, and a lack of consensus on whether the value elements included should vary by vaccination type or condition. We conducted a systematic review of value frameworks to identify broader value elements and measurement guidance that may be useful for capturing the full value of vaccination.

The 2022 Health Technology Assessment International (HTAi) Global Policy Forum (GPF) established the goal of developing a position statement and framework for lifecycle HTA (LC-HTA), through a Task Force leveraging multi-stakeholder monthly discussions and GPF member input. The Task Force developed a working definition: LC-HTA is a systematic process utilizing sequential HTA activities to inform decision making where the evidence base, the health technology itself, or the context in which it is applied, has a potential to meaningfully change at different points in its LC. Four key scenarios were identified where it was considered that an LC-HTA approach would add sufficient value to HTA bodies and their key stakeholders to justify the additional resource burden.

Health technology assessment (HTA) programs inform decision making about the value and reimbursement of new and existing health technologies; however, they are under increasing pressure to demonstrate that they are a cost-effective use of finite healthcare resources themselves. The 2023 HTAi Global Policy Forum (GPF) discussed the value and impact of HTA, including how it is assessed and communicated, and how it could be enhanced in the future. This article summarizes the discussions held at the 2023 HTAi GPF, where the challenges and opportunities related to the value and impact of HTA were debated.

The benefits of preventive interventions lack comprehensive evaluation in standard health technology assessments (HTA), particularly for rare and transmissible diseases. To identify possible considerations for future HTA using analogies between the treatment and prevention of rare diseases. An Expert panel meeting assessed whether one HTA assessment framework can be applied to assess both rare disease treatments and preventive interventions.

The Institute for Clinical and Economic Review (ICER) has emerged in a visible role in US health care. However, it is unclear to what extent US commercial health plans use ICER value assessments in their specialty drug coverage decisions. To evaluate the relationship between ICER's reported cost-effectiveness ratios (CERs) and coverage restrictiveness.

Lifecycle considerations have always been part of health technology assessment (HTA). However, the concept of taking a fuller, more holistic "lifecycle approach" is gaining interest in the HTA community. The 2022 HTAi Global Policy Forum (GPF) discussed how adopting a lifecycle approach could promote stakeholder engagement and robust evidence generation, and whether it could enhance information sharing and transparency across stakeholder groups.

Purpose: We aimed to investigate patient and caregiver views on the relative importance of traditional and nontraditional domains of value, and to determine if these views differed according to key demographic characteristics.

Patients And Methods: We conducted a modified Delphi approach using a web-based survey of adult patients managing a chronic condition or caregivers of a patient with chronic illness who were recruited using purposive sampling focused on demographic and clinical characteristics. The first survey round asked participants to rate the 13 domains of value on a 5-point Likert scale and rank each domain that they rated as important or very important.

Article Synopsis
  • Low-value care, like unnecessary PSA tests for prostate cancer, can lead to additional, costly follow-up services, highlighting a need for better evaluation of such practices.
  • The study assessed men aged 70 and older enrolled in a Medicare Advantage plan to analyze the costs and care associated with PSA testing, despite guidelines advising against routine screening in this age group.
  • Out of nearly a million participants, 38.6% underwent low-value PSA testing, with a significant percentage receiving follow-up services, indicating an increasing trend in test utilization from 2016 to 2018.

Background: Traditionally, economic evaluations have engaged clinicians and policymakers; however, patients and their caregivers have insight that can ensure that the economic evaluation process appropriately reflects disease consequences and adequately addresses their priorities related to treatment.

Objective: We aimed to identify patient priorities to inform an early economic evaluation of chimeric antigen receptor T-cell therapy for adults with relapsed or refractory B-cell acute lymphoblastic leukemia.

Methods: We conducted two online group discussions of four participants each, involving patients with experience of hematological cancer and a caregiver.

Low-value care is a major source of health care inefficiency in the US. Our analysis of 2009-19 administrative claims data from OptumLabs Data Warehouse found that low-value care and associated spending remain prevalent among commercially insured and Medicare Advantage enrollees. The aggregated prevalence of twenty-three low-value services was 1,920 per 100,000 eligible enrollees, which amounted to $3.

Background: In 2012, the US Preventive Service Task Force revised its recommendations for prostate-specific antigen (PSA) screening from "insufficient evidence" to "do not recommend" for men aged 70-74 while maintaining "do not recommend" for men aged 75+.

Methods: Using the difference-in-difference approach, we evaluated whether the rate of change in the use of low-value PSA screening differed between the control group (men aged 75+, N=7,856,204 person-years) and the intervention group (men aged 70-74, N=5,329,192 person-years) enrolling in the Medicare Advantage plan without a history of prostate cancer within the OptumLabs Data Warehouse claims data (2009-2019). A generalized estimating equation logistic model was specified with independent variables: an intervention group indicator, a pre- and post-period (after 2012 Q2) indicator, index time, and interaction terms.

Objectives: This study aimed to explore the impact of including broader value elements in cost-effectiveness analyses by presenting 2 case studies, one on human papillomavirus (HPV) infection and one on early-stage Hodgkin's lymphoma (ESHL).

Methods: We identified broader value elements (eg, patient and caregiver time, spillover health effects, productivity) from the Second Panel's Impact Inventory and the ISPOR Special Task Force's value flower. We then evaluated the cost-effectiveness of HPV vaccination versus no vaccination (case 1) and combined modality therapy (CMT) versus chemotherapy alone for treatment of adult ESHL (case 2) using published simulation models.
