HIV Cascade of care PreventionTesting Access/ Linkage to care Access to treatments (supply chain) AdherenceRetention

HIV Care & Prevention = prevention Access (Uptake) = prevention Adherence = prevention Retention Access + Adherence + Retention = Engagement

Two Randomized Controlled Trials (Kenya) March 27, 2011Nov 27, 2010 WelTel weekly SMS check-ins (two way): *24% improvement in achieving 95% adherence over 1y *19% improvement in achieving viral suppression at 1y (NNT = 9 & 11) SMS reminders/motivation (one way): *Weekly (short) messages 32% improvement in 90% adherence (MEMS) over 1y *9% decrease in treatment interruptions *No adherence improvement with daily, longer reminders *No viral load/clinical outcomes

Summary of RCT Evidence on mHealth Interventions to improve ART outcomes Adherence monitoring by SMS? - ? – not yet known if effective for adherence promotion – Challenging to implement, cost, compliance, stigma? Targeted adherence counselling? - Y – improves adherence and viral suppression (1yr) Digital alarm reminders? - N – No improvement on adherence or VL (1yr) One way cell phone SMS reminders? – N/Y – no improvement in adherence (by MEMS), for daily reminders – effective with short weekly messages. (1yr) Two-way cell phone SMS çheck-ins’/access to HCW? -Y – Improves adherence and viral suppression (1yr) Level of Evidence: Level of Evidence: Grade A (weekly SMS) Support (access to care) > Reminders?

My take home messages Keep it simple – Every extra step (complexity) loses someone Keep it low cost – Resource limited settings, vulnerable groups Conduct controlled studies – What really works, and what doesn’t? Seize the opportunity – mHealth is a gift
