Pink APP: Strategy for resolving breast cancer screening actions according to the ITABERAÍ project

Abstract

Objective: The ITABERAÍ Project is a phase III multicenter randomized clinical trial that deals with intervention through
training of community health agents (ACS) based on evidence of tracking in physical examination of the breast. This study
aimed to develop an application for a mobile device as a strategy for resolving ACS actions in breast cancer screening, based
on the ITABERAÍ Project. Methodology: The application was developed to be installed on the tablet used by the ACS, who
works in the Primary Health Care Network in the city of Itaberaí. The graphical interface of the application was developed
in Dart/Flutter, and for the back-end part, Python programming language was used, together with its Flask framework for
the creation of the application programming interface (API), which is responsible for making the communication between
the database data and the application. For the relational database, the MySQL software was used. The variables used to
build the application were sociodemographic data, life habits, anamnesis, previous examinations, and information about
the physical breast examination of women aged 40 years or older, residing in the municipality of Itaberaí. For analysis,
the database will be exported to the REDCap Platform (Research Electronic Data Capture). Results: The application was
validated with 235 entries, it is currently in version 1.5 and in use by 75 ACS. In the 4 months of use, 1,963 women were
registered, of which 1,261 (64%) were in the control group and 702 (36%) were in the intervention group. Conclusion: The
Pink APP proved to be easy to use and effective for collecting, storing, and exporting data for analysis, which can help
improve and manage public policies.
