Developing and pre-testing a digital decision-tree smartphone application for smoking prevention and cessation among HIV care providers.

Objectives: The diagnosis and continuous care of chronic conditions such as HIV infection present potential teachable moments for delivering smoking prevention and cessation interventions for patients. We designed and pre-tested a prototype of a smartphone application(app), Decision-T, specifically designed to assist healthcare providers when providing personalized smoking prevention and cessation services to their patients.

Methods: We developed the Decision-T app based on transtheoretical algorithm for smoking prevention and cessation following the 5-A's model.
