Barriers Perceived by Managers and Clinical Professionals Related to the Implementation of Clinical Practice Guidelines for Breastfeeding through the Best Practice Spotlight Organization Program

International institutions facilitate the contact of health professionals to evidence-based recommendations for promoting exclusive breast feeding (BF). However, the achievement of good rates of exclusive BF is still far from the optimum. The intention of the present work is to determine the barriers identified by managers and health professionals involved in the implementation and sustainability of Clinical Practice Guidelines (CPG) for breastfeeding under the auspices of the Best Practice Spotlight Organization program. A qualitative research study was carried out. The participants were managers, healthcare assistants, nurses, midwives, pediatricians and gynecologists. Semi-structured interviews were conducted which were transcribed and analyzed using the six steps of thematic analysis. Twenty interviews were conducted, which defined four major themes: (1) Lack of resources and their adaptation; (2) Where, Who and How; (3) Dissemination and reach of the project to the professionals; and (4) The mother and her surroundings. This research identifies the barriers perceived by the health professionals involved in the implementation, with the addition of the managers as well. Novel barriers appeared such as the ambivalent role of the midwives and the fact that this CPG is about promoting health. The efforts for promoting the implementation program should be continuous, and the services should be extended to primary care.
