Utilização de ferramentas estatísticas da qualidade aplicadas no protocolo clínico de sepse em ambiente hospitalar

Abstract

Sepsis is a serious clinical syndrome resulting from the body's dysregulated inflammatory response to an infection, which can progress to organ dysfunction, septic shock, and death. It is one of the leading causes of hospital mortality worldwide, with a high incidence and high healthcare costs, especially in intensive care units. In Brazil, mortality rates range from 40% to 60%, higher than in developed countries. Guidelines such as those from the Surviving Sepsis Campaign and the Latin American Sepsis Institute (ILAS) recommend early diagnosis and rapid intervention, including antibiotic administration within the first hour, laboratory testing, and hemodynamic stabilization. However, effective adherence to these protocols faces barriers such as diagnostic delays, gaps in care flow, and structural limitations. In this scenario, the application of statistical quality tools such as the Pareto Diagram, the Ishikawa Diagram, the FCA method, and the 5W2H action plan can help identify failures, analyze root causes, and implement continuous improvements. This study aims to evaluate the use of these tools in the implementation and monitoring of the sepsis clinical protocol in a hospital setting. The specific objectives included identifying failures in protocol adherence, analyzing their causes, proposing corrective actions, and monitoring clinical indicators to verify the effectiveness of interventions. The results were expected to contribute to reducing sepsis-associated mortality, promoting greater patient safety, and strengthening the integration of quality management methodologies into hospital practice. The study also aimed to develop adapted tools for continuous assessment of the effectiveness of sepsis protocols, serving as a reference for other healthcare institutions.
