Integrated health technological solution for the resolution of breast cancer screening actions: Itaberaí Project

Abstract

Objective: This study aimed to present the technological solution of the ITABERAÍ Project, characterizing a set of services and applications to integrate actions from the registration of study participants to the follow-up of altered cases.
Methodology: The technological solution involves integrating the mobile application (Rosa App) with the web system
(RosaWatch). The App was developed for use by the Community Health Workers (CHW), in collecting data on study participants, and the system was created for the follow-up of altered cases, from suspicion to diagnostic confirmation and
initiation of treatment, and is used by coordinators of the National Health Strategies (NHS), regulation, specialists, and
participating study centers. The graphical interface of the App was developed in Dart/Flutter, and the Backend was written in Python/Flask for the creation of the application programming interface (API), responsible for communication
between the database and the application. For the relational database, MySql is used. The web system was designed in
Python/Flask, and for HTML pages, CSS/Bulma and Javascript were used. For analysis and interpretation, the database
is exported to the RedCap Platform. Results: Currently, there are 98 users, all of whom have received training for the use
of the technological platforms, with good acceptance and high rates of proper completion. So far, 3101 women have been
randomized, with 1607 (51.8%) in the control group and 1494 (48.2%) in the intervention group; of these, 235 (15.7%) have
already completed Cycle 2 of the trial. The App is in version 1.8, and the web system is in version 1.1. Conclusion: The
technological solution proved to be an important strategy for consolidating information and facilitating the follow-up of
altered cases identified by both CHW and NHS. It is user-friendly and effective for data collection, storage, and export for
analysis, which contributes to the resolution of actions for breast cancer screening and the improvement of public policies.
