La Méthode S.I.I.P.S is a practical guide published in 1999 that presents a systematic approach to evaluating activity indicators in nursing care. Authored by Beaughon, the book outlines a framework designed to help healthcare professionals assess and improve the quality of patient care through measurable indicators. Spanning 101 pages, the text combines theoretical explanations with practical examples, making it suitable for both nursing students and practicing clinicians seeking to implement evidence‑based evaluation methods. The methodology emphasizes clarity, reproducibility, and relevance to clinical settings, aiming to bridge the gap between everyday nursing activities and formal quality assessment. Although the work is rooted in the French healthcare context, its principles can be adapted to various international nursing environments. The book remains a reference for those interested in nursing management, quality improvement, and the development of performance metrics in healthcare.
