[EBM, guidelines, protocols: knowledge, attitudes and utilization in the era of law on professional responsibility and safety of health care.].

Introduction: The knowledge of principles and methods of Evidence Based Medicine (EBM) and the use of Clinical Practice Guidelines to inform clinical decisions are recognised as key instruments to improve the quality of care. In Italy the Parliament has revised the legal system that rules the responsibilities of health professionals and health care safety, prescribing health professionals to adhere to guidelines and good practice recommendations. The objective of the study was to evaluate guidelines and clinical pathways developed at local level and to assess knowledge and attitudes of healthcare workers toward EBM and guidelines.

Methods: At the l'ASL 5 Liguria La Spezia we performed a census of all the documents registered as "guidelines" or "clinical pathways" at the Direzione Generale by the end of May 2016. We assessed their methodological quality by the "Recognition Card for Clinical Pathways Production and Revision Activity" prepared by the Ligurian Region. We conducted semi-structured interviews to assess attitudes and knowledge of healthcare workers.

Results: We found 17 clinical pathways, 41% contained organizational/management recommendations, and 59% contained mainly clinical recommendations. 41% was produced by assimilating already existing guidelines. 29% did not describe the method of production. Only one document linked directly each recommendation with scientific evidence. 10 healthcare workers out of 32 invited actually accepted to conduct the interview. Respondents showed a positive attitude toward the EBM and guidelines but a poor knowledge of the methodology of production and the instruments and principles for critical appraising of scientific literature. Nobody knew the GRADE approach. The most relevant barriers identified were: lack of time, poor knowledge of English and statistical methods, poor applicability of the international guidelines to local setting and real patients encountered in clinical practice.

Discussion: Despite the initiatives of the legislator toward civil responsibility and safety of care that should increase the use of guidelines, we found an overall poor knowledge of the concepts of EBM and method of guidelines production. Though the attitudes of responders to the interview were positive, barriers to use seemed to be predominant and considered more as obstacles than as a stimulus. In peripheral settings or in hospitals of medium/small size, clinical guidelines could remain confined to a merely juridical role, with weak impact on professional practice.
