Análisis causal integrado en la radiosinoviortesis y el tratamiento mielosupresor de la policitemia vera / Integrated causal analysis in radiosynoviorthesis and the myelosupressor treatment of polycythemia vera

Introducción: Con la matriz de riesgo se identifican las medidas de control relevantes. El análisis de modos y efectos de fallo posterga definir la efectividad de las medidas correctivas. El uso de uno solo de estos métodos limita el alcance al evaluar los riesgos y la toma de decisiones. Objetivos: Determinar la contribución individual de las causas básicas de fallo en el riesgo radiológico de la radiosinoviortesis y el tratamiento mielosupresor de la policitemia vera, a partir del modelo de la matriz y los reportes. Métodos: Se adaptó el análisis de la gestión de la calidad en radioterapia a las prácticas en estudio y la selección individual de las causas básicas más contribuyentes al riesgo radiológico. La base internacional de incidentes aportó las causas que completaron el listado de las derivadas de la aplicación del principio de Pareto. Resultados: Los subprocesos más contribuyentes al riesgo fueron, por orden de importancia, la administración del radiofármaco, su preparación y la prescripción clínica. Para estos se identificaron las etapas, modos de fallo y sus causas más importantes. Existieron causas que contribuyeron a varios modos de fallo. El incumplimiento de procedimientos, protocolos o prácticas, la falta de entrenamiento del personal y la fatiga del personal son las causas de los riesgos identificados. Conclusiones: Se caracterizó la efectividad de las medidas correctivas de las causas más contribuyentes, las que se adicionan a las derivadas de la matriz, en el plan de mejora en la radiosinoviortesis y el tratamiento mielosupresor de la policitemia vera en Cuba(AU)

Introduction: The risk matrix identifies the relevant control measures. Failure modes and effects analysis postpones defining the effectiveness of corrective measures. Using just one of these methods limits the scope when assessing risks and making decisions. Objectives: To determine the individual contribution of the basic causes of failure in the radiological risk of radiosynoviorthesis and the myelosupressor treatment of polycythemia vera, based on the matrix model and the reports. Methods: The analysis of quality management in radiotherapy was adapted to the practices under study and the individual selection of the basic causes most contributing to radiological risk. The international incident base provided the causes that completed the list of those derived from the application of the Pareto principle. Results: The sub-processes that contributed the most to risk were, in order of importance, the administration of the radiopharmaceutical, its preparation and the clinical prescription. For these, the most important, stages, failure modes and their causes were identified. There were causes that contributed to various failure modes. Non-compliance with procedures, protocols or practices, lack of staff training and staff fatigue are the causes of the identified risks. Conclusions: The effectiveness of the corrective measures of the most contributing causes, which are added to those derived from the matrix, was characterized in the improvement plan in radiosynoviorthesis and myelosupressor treatment of polycythemia vera in Cuba(AU)

Process control of maintenance management for large medical equipment / 中国医学装备

Objective:To explore the process of maintenance management for large medical equipment, and the structure design and core connotation of the maintenance management software of them.Methods: Medical linear accelerator of Precise series of Elekta company was combined to achieve the objective. From the aim of designing normal operation rate to start, the failure mode and effects analysis (FMEA) was operated to analyze the maintenance strategies and maintenance manners which were established on the basis of PDCA(Plan, Do, Check, Action) cycle and the analysis mode of SWOT (Strength, Weakness, Opportunity, Threat), and it could achieve the aim of normal operation rate.Results: Through explored the connotation of maintenance management and the preliminary framework of the software of maintenance management, the detail and process of maintenance management that based on personalized accelerator of process control were established, and the element factors of software of maintenance management of accelerator also was established at the same time.Conclusion: The effective maintenance management of large medical equipment is based on informatization process management of process control, and the element factor of management software need personalized customization. On the other hand, failure mode and degradation mechanism of equipment were the basis for personalized customization, and the creation has practical value.
