Second edition of the 'do not do' recommendations from the Spanish Society of Endocrinology and Nutrition (SEEN).

Abstract

Low-value clinical practices - defined as diagnostic or therapeutic interventions that provide limited clinical benefit and may be associated with unnecessary risks or costs - remain common in endocrinology and nutrition. The Spanish Society of Endocrinology and Nutrition (SEEN) presents this second edition as an updated set of recommendations on "what not to do" in clinical practice, developed by its sections and working groups. The methodological process included the selection of relevant topics, systematic literature review, and multidisciplinary consensus. Key areas addressed include diabetes, obesity, nutrition, gonads, lipids, laboratory, mineral metabolism, and imaging, identifying low-value interventions and offering alternatives based on the best available evidence. The implementation of these recommendations aims to optimize care quality, reduce risks, and contribute to the sustainability of the healthcare system.
