Development and implementation of guidelines constitutes the basis of quality management systems for any organization. The authors have studied the internal documentation produced by professionals on 88 functional units of a university hospital. Reveals the existence of many documents concerning quality of care with an average of 102 available procedures or protocols per unit. However, this documentation is badly organized, making it difficult to consult and to put into practice. The results of this study were provided to other professionals at our hospital in order to make them aware of the necessity of rigorous document management. We have also written and sent recommendations for drawing up procedures and implementing an efficient documentary management system. This effort complements development of the hospital quality assurance plan.
