Abstract
Introduction

In response to the increasing demand for radioguided procedures, the integration of the Nursing Care Assistants (TCAE) profile was proposed as support professionals in the preoperative marking of breast cancer (BC) patients using I-125 seeds.

Objectives

To analyze the clinical impact and professional development resulting from the integration of TCAE into these procedures, assessing the operational efficiency of the Radioguided Surgery Team (EQCRG) and the training process that enabled them to assume new competencies.

Materials and methods

A four-phase theoretical-practical training program was implemented (theoretical instruction, practical mentoring, clinical simulation, and supervised autonomous practice), aimed at training TCAE to assist in the localization and marking of non-palpable lesions and metastatic axillary lymph nodes using I-125 seeds. After completing the training, their impact was evaluated through a comparative analysis of EQCRG activity in 2023 and 2024.

Results

During the study period, TCAE autonomously performed 116 marking procedures with I-125 seeds without incidents, accounting for 11.8% of total procedures in 2023 (32/270) and 23% in 2024 (84/366). Operational support was required on 21 working days in 2023 (8.5%) and 49 days in 2024 (19.6%), indicating a significant increase in their involvement.

Conclusions

The incorporation of the TCAE profile into radioguided marking procedures has proven to be an effective strategy for optimizing healthcare resources, enhancing the operational efficiency of the EQCRG, and promoting the professional development of this role within highly specialized clinical settings.

Resumen
Introducción

Ante el aumento de la demanda asistencial en procedimientos radioguiados, se propuso incorporar el perfil Técnico en Cuidados Auxiliares de Enfermería (TCAE) como profesional de apoyo en el marcaje prequirúrgico con semillas de I-125 en pacientes con cáncer de mama (CaM).

Objetivos

Analizar el impacto asistencial y el desarrollo profesional derivados de la integración del TCAE en estos procedimientos, evaluando la eficiencia operativa del equipo de cirugía radioguiada (EQCRG) y el proceso formativo que les permitió asumir nuevas competencias.

Material y métodos

Se implementó un programa de formación teórico-práctico en cuatro fases (formación teórica, acompañamiento práctico, simulación clínica y práctica autónoma supervisada) orientado a capacitar al TCAE para asistir en la localización y marcaje de lesiones no palpables y ganglios linfáticos axilares metastásicos con semillas de I-125. Tras la formación, se evaluó su impacto mediante un análisis comparativo de la actividad del EQCRG en 2023 y 2024.

Resultados

Durante el periodo analizado, las TCAE realizaron 116 procedimientos de forma autónoma y sin incidencias, representando el 11,8 % del total en 2023 (32/270) y el 23 % en 2024 (84/366). El soporte operativo fue requerido en 21 jornadas en 2023 (8,5 % de los días laborables) y en 49 jornadas en 2024 (19,6 %), reflejando un aumento significativo en su participación.

Conclusiones

La incorporación del perfil TCAE en procedimientos de marcaje radioguiado ha demostrado ser una estrategia eficaz para optimizar recursos asistenciales, mejorar la eficiencia operativa del EQCRG y fomentar el desarrollo profesional de este perfil en entornos asistenciales de alta especialización.
