Aplicativo móvel e simulador para treinamento de habilidades em punção aspirativa por agulha fina

Abstract

This study aimed to develop a simulator that would enable veterinary medicine students to practice fine needle aspiration (FNA), assess their level of satisfaction and self-confidence in learning and create a mobile application for data collection and monitoring of neoplasms. mammary glands in bitches. The simulator was developed using a canine mannequin, made of leatherette. The breast region was simulated with an elastane mesh, which was subdivided into eight compartments where male condoms were inserted with varying amounts of hydrated disposable diaper gel, containing different elements simulating nodules and tumor masses, allowing the practice of the FNA technique. The mobile application was developed using HTML 5, CSS 3 technologies, responsible for the system's appearance; SQL to create the database, storing and organizing them; Javascript to validate the data, i.e. fetch and take information from the system to the storage database vice versa; PHP that acts as an intermediary, allowing the registration of various forms to create a complete profile of the animal to be served, in addition to easily managing the information. The data collected from the simulator were analyzed using frequency distributions for the responses given on a Likert scale. Fisher's exact test was used to compare groups, and the Mann-Whitney and Kruskal-Wallis tests were used for quantitative variables, when appropriate. The significance level adopted was 5%. To characterize the participants of the mobile application, frequency distribution and summary measure calculation were used. Questionnaire responses were evaluated using frequency distributions and for responses given on a Likert scale, a bar graph was presented. The RStudio software was used to assist the analyses. The simulator was tested by 60 undergraduate Veterinary Medicine students and 100% felt satisfied with the learning and self-confident in performing the FNAC. The mobile application was evaluated by specialists in pathology, oncology and mastology, where a neutral answer appeared in 12.5% and 25.0% of the questions, and negative answers in only 12.5% of the items referring to the quality of the software. When classifying the system's usability using the SUS scale questionnaire, we observed that 62.5% considered it excellent, 25% good and 12.5% average. It is concluded that training focused on developing fine needle aspiration (FNA) skills in animals, using a low-fidelity simulator, has positive impacts on both students' learning and their self-confidence in relation to collection. The developed application reached a satisfactory level of software quality and usability, being considered useful by the study participants.
