Development and Validation of a Health Information System for Assistance and Research in Gestational Trophoblast Disease

Abstract Background: The aim of this work was to develop and validate a Health Information System (HIS) composed of a Web interface for the medical team of the Gestational Trophoblastic Disease (GTD) Outpatient Clinic, as well as a MolaApp Application for patients, as it portrays a interaction between two technological devices with simultaneous application to assist in treatment, reducing time, cost and improving the quality of communication between doctors and patients. Regarding gestational trophoblastic disease, it encompasses all pathological forms of placental trophoblastic tissue proliferation. It is recommended that the patient be followed up by specialists who know the dosage of the hCG curve, in order to diagnose early evolution to a Gestational Trophoblastic Neoplasm (GTN).Methods: For the development of SIS-Mola, a team was formed with a project manager, a requirements analyst, two programmers and four systems analysts. This is a cross-sectional technological assessment research and the project phases were defined by techniques used by software engineering that covered requirements analysis, programming and development of tools, as well as test and questionnaire applicability. The study was systematized through the intrinsic parameters of care at the GTD Outpatient Clinic.Results: The tests were carried out from November 2021 to February 2022, with an invitation to 28 eligible participants to proceed with usability and functionality assessments, using a questionnaire based on the System Usability Scale - SUS and an occurrence questionnaire. The responses obtained on the Likert scale indicated excellent reliability and credibility to the HIS. In addition, participants reported high intention to use and recommend digital tools to other Reference Centers in Brazil, suggesting additional improvements.Conclusion: The HIS, after the final results, proved to meet the essential activities of the Outpatient Clinic specialized in GTD, in the treatment of the disease, because it is technically adequate, practical and easy to handle the tools between its interfaces, as well as for the efficiency for the organization in the flow of the service, in the quality of the assistance provided and in the creation of a database that will allow accurate studies for continued education, professional and scientific improvement.
