OBJECTIVES/GOALS: This project will design, develop and pilot-test a Spanish-mobile application for breast cancer patients. It is intended that patients will improve treatment adherence, have a personal information storage system for their follow-up healthcare and can have greater control in the processes of diagnosis, treatment, education, and recovery. METHODS/STUDY POPULATION: In the first phase, a team of undergraduate engineering students was recruited to work on the areas of: Front End, Database Development, Security Protocols, and Integration. Team Venus will provide the cancer-related content. In the second phase, the engineering team will identify bugs, usability, satisfaction, and workability of the application among a pilot convenience sample of 20 participants from four cancer clinics and the community. The inclusion criteria are being > 21 years old and having a cell phone. The exclusion criterion is not knowing how/being able to use a mobile application. Participants will complete a questionnaire on sociodemographic data, mobile phone and application use, efficacy, usability, and security. Univariate and bivariate statistical analysis will be performed using SPSS. RESULTS/ANTICIPATED RESULTS: The researchers are defining specific visual and content features they would like the application to have. They are also searching and collecting reliable information about cancer from primary sources to incorporate into the tools available to the application’s users. In addition, they have also begun to identify potential cancer treatment facilities and medical personnel to assist in the recruitment of patients for pilot-testing the application. The researchers have divided them into geographical areas in Puerto Rico and each Team Venus member will approach and orient patients and medical personnel about the project. DISCUSSION/SIGNIFICANCE: It is intended that patients will improve treatment adherence, have a storage system for their follow-up healthcare and greater control in their processes of diagnosis, treatment, education, and recovery. Future goals include use of the database feature by researchers and expanding the testing of the application with a larger patient-base.
