RT Journal Article SR Electronic T1 Age change in healthcare settings: a reply to Lippert-Rasmussen and Petersen JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 636 OP 637 DO 10.1136/medethics-2020-106144 VO 46 IS 9 A1 Joona Räsänen YR 2020 UL http://jme.bmj.com/content/46/9/636.abstract AB Lippert-Rasmussen and Petersen discuss my ‘Moral case for legal age change’ in their article ‘Age change, official age and fairness in health’. They argue that in important healthcare settings (such as distributing vital organs for dying patients), the state should treat people on the basis of their chronological age because chronological age is a better proxy for what matters from the point of view of justice than adjusted official age. While adjusted legal age should not be used in deciding who gets scarce vital organs, I remind the readers that using chronological age as a proxy is problematic as well. Using age as a proxy could give wrong results and it is better, if possible, for states to use the vital information directly than use age as a proxy.
