Wrong guidelines: How to detect them and what to do in the case of flawed recommendations

Any evidence-based recommendation needs careful assessment of its methodological background as well as of its content trustworthiness, especially given that following it will not necessarily produce the intended clinical outcomes. There are no established instruments to evaluate guidelines for their content, while useful tools assessing the quality of methods followed are well recognised and adopted. We suggest a 'safety bundle' considering methodological aspects and content trustworthiness of guidelines, by adopting the GRADE method in a backward fashion. Sharing the critical analysis of the guidelines with patients, including any eventual uncertainty about them, is of key importance in order to avoid the possible adverse effects derived from following the wrong guidelines. Such critical approach is also helpful and beneficial in producing better care pathways, health policy decisions and more relevant and ethical research.
