Title: Do Smartphones Increase Linkage to and Retention in Care in Newly Diagnosed HIV-positive Patients in Johannesburg, South Africa: A Multisite Randomised Controlled Trial
Brief Summary: This randomized controlled trial evaluates the provision of individual patient laboratory results to newly diagnosed HIV positive smartphone users through a secure application (app) as a method to get them linked to and retained in care, and engage with educational materials purposefully developed to explain their results. Message prompts will also be used to alert patients that their results are ready and provide information on how to link to care, and assistance to re-link to care if they fall out of the health system for any reason. Prompts will be sent to patients to remind health care workers if they are due for repeat laboratory monitoring. The primary endpoint is linkage to care (a HIV-related laboratory test) at 6 months. The control group received standard of care.
