[Viewpoint] A public health perspective on assisted dying and its different modalities

Assisted dying (encompassing euthanasia and assisted suicide) has emerged as a legally sanctioned option for end-of-life care in an increasing number of countries. Over 200 million people now live in jurisdictions permitting some form of assisted dying, with at least 12 countries having implemented national or subnational legislation as of May, 2025. Legal frameworks, terminology, and procedures remain highly heterogeneous, affecting how assisted dying is perceived, delivered, and monitored. Terminological variation and the absence of specific ICD codes impede international data comparability, limiting public health surveillance and cross-country learning.
