Abstract

INTRODUCTION:

Along with the exponential growth of technology, the use of mobile devices in health, or mHealth, has been quickly becoming a viable practice to strengthen health systems, especially in low-resource settings. Nevertheless, the majority of mHealth interventions are pilot efforts which mostly lack robust design and evidence about the use of mHealth in public health. This study assessed the use of a bi-directional Short Message Service (SMS) in disease surveillance in Vietnam and aimed to bring evidence in improving engagement of health staff as well as the quality of reporting.

METHODS:

Eighty health staff from fourty communes of Hoa Binh and Hung Yen provinces were trained and participated in two 6-month pilots: one with one-way, and one with a bi-directional SMS system for assisting in error screening, and reminder and feedback provision to report two diseases: influenza and diarrhea using cell phones. After each examination and checking-in onto the paper logbook, participants reported the case by texting an SMS to a designated number and made notes of successfully reported cases. A central data repository server was set up to collect SMS reports, and aggregate reported patient data. Engagement of health staff and quality of the reporting work were assessed by the evaluation of the qualitative questionnaires, and the comparison of the texted SMS reports to the patient logbooks.

RESULTS:

With the use of a two-way versus one-way SMS system, participants were 4.6 times more likely (95 percent Confidence Interval, CI 3.93-5.44, p< .001) to send correctly formatted text reports, and 3.4 times more likely (95 percent CI 2.72-4.33, p< .001) to have precise information in their texted messages. Results also revealed that while their position, age, or gender of participants did not statistically influence the results, ethnicity and management roles did.

CONCLUSIONS:

The study showed that the use of a bi-directional SMS-based reporting system both significantly improved participants engagement in the reporting protocol, and greatly enhanced their reporting quality. The study demonstrated that robust evidence of a practical utilization of SMS in a disease reporting system to replace the traditional paper-based one has great potential for a scale-up and national-wide implementation.
