The project goal is to research and identify a confidential and technologically feasible method to communicate HIV/STD and preventive EOB information to young woman ages 19 to 25 through a moble application. Engineered Care will speak with privacy and HIPPA experts, payors, technology experts managing payor claims data and youth advocates to prototype a feasible smartphone mobile application. EC identified a list of key characteristics to rank features for the moile application (i.e. from data security, messaging clarity, to technology support cost). Key stakeholders and EC will use the characteristics list as a grading rubric when evaluation application features.
