Globally, malaria kills between 600,000 and 1.2 million people each year and is a leading cause of sickness and death across much of sub-Saharan Africa. Most killed are young children and pregnant women.
Only one class of antimalarial medication remains fully effective in Africa as a means of curbing this mortality -- artemisinin-based combination therapies (ACTs). Therefore, the appropriate use and completion of ACTs by infected individuals is a critical global health concern.
This randomised-controlled trial (RCT) tests the effectiveness of SMS reminders on increasing patient completion of ACTs in Ghana’s northern region. The data, collected in 2011, coincided with a rapid increases in ACT accessibility (availability and affordability) to patients. This access, however, can only translate into improved health outcomes and a delay in the development of parasite resistance if patients use ACTs -- and use them correctly.
This talk will cover three main aspects of this randomised-controlled evaluation:
• The main result that SMS reminders improved ACT completion by 5 percentage-points, from 61.5 to 66.4 percent, which is significant statistically and as a proof-of-concept for direct-to-patient SMSs in a high-poverty, limited-literacy setting.
• Lessons from implementing this intervention with a variety of ACT providers.
• Lessons for research design from the logistical complexities of this test of a ‘simple’ intervention.
