Dietitians' role in decisions to withhold nutrition and hydration

Decisions to limit nutrition and hydration in irreversibly or terminally ill patients are becoming more frequent in both hospitals and home-care settings. Although clear-cut principles or rules are not always possible, appropriate decisions about any form of life-sustaining treatment, nutrition and hydration included, require conducting a productive moral conversation within the medical management team and/or the institutional ethics committee. In this article, we discuss how dietitians can participate in these medical decisions.
