In recent years pediatric guidelines have increasingly become part of clinical practice, in Italy too. Aim of the present work is, on the basis of a review of national and international literature, to focus on the Italian situation about the use of guidelines in pediatric emergency, with particular respect to methodology, correct use, and related risks and benefits. The developing of efficient guidelines is achieved in different steps: 1) identifying and refining the topic for guidelines, in order to obtain an improvement of healthcare; 2) correct developing strategies, based on scientific evidence, leading to production of recommendations validated by external review; 3) adequate implementation and diffusion in local settings; 4) application with sensible and appropriate clinical discretion. Benefits obtained with the correct use of efficient pediatric guidelines, can be identified at different levels: patients' care (outcome improvement, increased patients' consciousness, influence on public healthcare policy); healthcare professionals (improving quality of clinical decisions, agreement on clinical and therapeutic strategies; medicolegal protection, representing a reference for prospective and retrospective audits); healthcare systems (standardising care, improving efficacy of care; optimising costs). Personal experience in systematic development of emergency pediatric guidelines, applied in a second level Emergency Department is also presented.
