The new definition of early Health Technology Assessment: implications for incorporating environmental sustainability

The objective of this paper is to present the Environmental Sustainability in Health Technology Assessment (ESHTA) Working Group's (WG's) opinion on the definition and scope of early Health Technology Assessment (HTA) developed by a WG under HTA International. The aim is to provide suggestions on how early HTA can support the goals of enhancing environmental sustainability in healthcare.

The HTAi ESHTA WG presents our opinion on the proposed definition and scope of early HTA. This includes a broad range of perspectives from stakeholder groups including patient experts, a policy maker, a statistician, HTA researchers and a healthcare professional, located across lower to higher resource settings and several jurisdictions. We suggest how early HTA can support the goals of enhancing environmental sustainability in healthcare.

HTA agencies play a crucial role in embedding sustainability into their evaluations and practices. Integrating environmental sustainability into HTA at three critical stages - product conceptualization, reimbursement decisions, and point of care - can optimize resource use and reduce environmental impacts. Developing sustainability metrics, defining environmental impact categories, and identifying suitable methods for assessing health technologies are essential steps. Early engagement is also vital for optimizing trade-offs and increasing acceptance by diverse stakeholders.

Incorporating environmental sustainability into early HTA can enhance the likelihood of regulatory approval and reimbursement, ultimately benefiting patients and healthcare systems. By integrating sustainability considerations at the design stage, the potential for environmental impact reduction is maximized. Future efforts should focus on developing comprehensive guidelines and methods, ensuring collaboration between early HTA and ESHTA WGs.
