Introducci?n: La seguridad del paciente se define como la reducci?n del riesgo de da?os innecesarios relacionados con la atenci?n sanitaria. Hasta un 9,3% de los pacientes que ingresan en un centro hospitalario presentan alg?n evento adverso relacionado con la asistencia. Esto puede provocar da?o para el paciente, mayor instrumentaci?n, incremento de la morbilidad, incremento de la estancia hospitalaria e incremento del coste. Para identificar, registrar y analizar los eventos adversos es necesario disponer de un sistema de notificaci?n de incidentes. Objetivo: Elaborar un sistema local para la notificaci?n de incidentes de seguridad y eventos adversos en cirug?a de la gl?ndula tiroides. M?todo: Se form? un grupo de trabajo con representaci?n de todas las unidades relacionadas con el proceso de tiroidectom?a, se establecieron los puntos de control, se dise?aron listados de verificaci?n para cada punto de control, se realiz? un an?lisis estrat?gico sobre la actividad del grupo, se realiz? una revisi?n bibliogr?fica para identificar los principales sistemas de notificaci?n de incidentes, se identificaron los ?tems que deber? tener el formulario de notificaci?n de incidentes y se dise?? el formulario. Resultados: El formulario de notificaci?n de incidentes recoge datos relativos al paciente, al comunicador y al incidente (tipo, causa, consecuencia, gravedad, frecuencia, matriz de riesgos). Tiene una primera parte con apartados narrativos y una segunda con listas desplegables. El formulario es accesible exclusivamente para el grupo de trabajo, de uso voluntario. Conclusiones: El objetivo del sistema de notificaci?n es el aprendizaje y la prevenci?n.

Introduction: Patient safety is defined as the reduction of risk of unnecessary harm associated with healthcare. Up to 9.3% of patients admitted into a hospital present some adverse event related to the assistance. This can cause damage to the patient, more instrumentation, increased morbidity, increased hospital stay and increased cost. To identify, record and analyze adverse events is necessary to have an incident reporting system. Objective: Developing a local system for reporting security incidents and adverse events in surgery of the thyroid gland. Method: A working group was formed with representatives from all units related to the process of thyroidectomy, checkpoints were established, checklists for each control point were designed, a strategic analysis of the group's activity was performed, a literature review was done in order to identify the major incident reporting systems, the items that the incident report form must have were identified and the form was designed. Results: The incident report form collects data on the patient, the communicator and the incident (type, cause, consequence, severity, frequency, risk matrix). It has a first paragraph with narrative sections and a second with drop-down lists. The form is accessible only to the working group for voluntary use. Conclusions: The purpose of the reporting system is learning and prevention.
