Retention in HIV primary care Using a web-based patient engagement platform

Abstract

Background: Digital interventions to improve retention in HIV care are critical to ensure viral suppression and prevent further transmission. AIDS Healthcare Foundation Healthcare Centers are centers across the United States that provide primary HIV care. Traditionally, the Healthcare Centers conduct phone calls with patients to schedule and confirm appointments, as well as share laboratory results. In 2017, Healthvana piloted a digital platform at AIDS Healthcare Foundation Healthcare Centers to send patients SMS text message appointment reminders and allow patients to review their upcoming appointment and view their laboratory results in the web-based patient portal. Objective: A national implementation in 15 US states and Washington, DC, of this digital intervention pilot by Healthvana aims to determine whether SMS appointment reminders and web-based patient portal logins improved retention in care compared to traditional methods. Methods: A retrospective analysis of 40,028 patients living with HIV was conducted at the 61 AIDS Healthcare Foundation Healthcare Centers between January 2, 2017, and May 22, 2018. Patients were invited to enroll in Healthvana's digital intervention pilot, allowing for a natural, organization-wide case-control study. Separate binary logistic regression models evaluated the relationship between receiving SMS appointment reminders and completing scheduled appointments, as well as the relationship between logging into the web-based patient portal and completing scheduled appointments. Four scheduled consecutive appointments for each patient were included in the analysis to account for 1 full year of data per patient. Results: Patients who received the SMS appointment reminder were 1.7 times more likely to complete appointment 1 compared to patients who did not receive the SMS appointment reminder (P<.001). In addition, patients who received the SMS appointment reminder were 1.6 times more likely to complete appointment 2 (P<.001), 1.7 times more likely to complete appointment 3 (P<.001), and 1.8 times more likely to complete appointment 4 (P<.001) compared to patients who did not receive the SMS appointment reminder. Patients who logged in to the web-based patient portal prior to their scheduled appointment were 7.4 times more likely to complete appointment 1 compared to patients who did not log in (P<.001). In addition, patients who logged in to the web-based patient portal prior to their scheduled appointment were 3.6 times more likely to complete appointment 2 (P<.001), 3.2 times more likely to complete appointment 3 (P<.001), and 2.8 times more likely to complete appointment 4 (P<.001) compared to patients who did not log in. Conclusions: HIV primary care appointment completion was higher when patients engaged with Healthvana's digital platform. Digital technology interventions to ensure patients complete their scheduled HIV care appointments are imperative to curb the HIV epidemic.
