RESUMO
Introduction The amputation of the upper limb, especially of the hand, is a serious trauma with significant functional and psychological impact. Treatment options include adaptation to the stump, use of prostheses, and composite tissue transplantation. Unfortunately, in Colombia, to date, there are no epidemiological data that characterize the sociodemographic and clinical variables of patients with upper limb amputation. Objective To describe the clinical and epidemiological characteristics of patients with upper limb amputation in two hospital institutions in the city of Medellín during the period 2018-2019 as a basis for developing a hand transplant program in Colombia. Methods A descriptive cross-sectional study was carried out where a total of 443 medical records were reviewed, of which eight records that met the inclusion criteria were identified. Variables such as age, etiology of amputation, level of amputation, comorbidities, complications, and rehabilitation process were analyzed. The information was collected in the REDCap program, and a descriptive analysis was carried out with the data obtained. Results From a sample of 443 amputee patients, eight were selected that met the inclusion criteria. There were 7/8 men (87%) aged 43 years. A total of 75% came from rural areas. In 3/8 patients, there was amputation of the dominant limb. The most common mechanisms were shear trauma and crushing in the context of an occupational accident. A total of 50% had a complete extra-hospital amputation, and reimplantation was not attempted in any of the cases. The most frequent levels of amputation were the proximal and distal third of the forearm. The longest follow-up time was 12 months. Only two patients mentioned the possibility of using a prosthesis during rehabilitation. Conclusions Three young patients were identified, without comorbidities, with amputation of the dominant limb in the context of an occupational accident and without the possibility of rehabilitation with prostheses who benefit from a possible future hand transplant. However, it is necessary to implement a composite tissue transplantation program and public health policies that allow this procedure to be performed in Colombia.
RESUMO
Introducción. La simulación como estrategia de aprendizaje activo se ha constituido en una herramienta centrada en el estudiante, para la construcción de aprendizajes en entornos seguros y el perfeccionamiento de sus habilidades técnicas. La evaluación objetiva estructurada de habilidades técnicas (OSATS, por sus siglas en inglés) es una herramienta evaluativa en el área quirúrgica, que puede ser implementada en los programas en microcirugía. Métodos. Estudio descriptivo, de corte transversal y doble ciego, donde se incluyeron 34 estudiantes de especialidades quirúrgicas, quienes fueron evaluados mediante los OSATS para los módulos finales: módulo 1: disección vascular; módulo 2: ejecución de sutura de puntos independientes; y módulo 3: ejercicios de revascularización. Al finalizar la materia, los estudiantes evaluaron la implementación de esta metodología por medio de una encuesta de satisfacción. Resultados. La evaluación del diseño de la guía práctica tipo OSATS por los estudiantes fue satisfactoria (88,2 %). Al evaluar la actividad de disección y sutura en microcirugía la consideraron de gran utilidad (88,2 %), para los ejercicios de anastomosis y revascularización (aprobación del 79,5 %). La aplicabilidad práctica y la calidad de los ejercicios mediante guías de evaluación OSATS tuvieron 94,2 % de aceptación. Conclusión. Las escalas OSATS son un instrumento útil, valido y objetivo para el modelo de evaluación por competencias en habilidades técnicas, que puede ser implementado en los modelos de enseñanza en simulación, contando con confiabilidad, validez de contenido y de constructo. Es aplicable en los programas de microcirugía, con una percepción positiva por parte de los estudiantes.
Introduction. Simulation as an active learning strategy has become a student-centered tool for the construction of learning in safe environments and the improvement of their technical skills. The Objective Structured Assessment of Technical Skills (OSATS) is an evaluation tool in the surgical area, which can be implemented in microsurgery programs. Methods. Descriptive, cross-sectional and double-blind study, which included 34 students from surgical specialties, who were evaluated through the OSATS for the final modules: module 1: vascular dissection; module 2: execution of independent sutures; module 3: revascularization exercises. At the end of the course, the students evaluated the implementation of this methodology under evaluation by means of a satisfaction survey. Results. The evaluation of the design of the practical guide OSATS-type by the students was satisfactory (88.2%). When evaluating the dissection and suturing activity in microsurgery, they consider it very useful (88.2%), for anastomosis exercises and revascularization exercise (79.5% approval). The practical applicability and quality of the exercises using OSATS evaluation guides had 94.2% acceptance.Conclusion. The OSATS scales are a useful, valid and objective instrument for the evaluation model for technical skills, which can be implemented in simulation teaching models, with reliability, content and construct validity. It is applicable in microsurgery programs, with a positive perception by students.
