Introduction: Current disease surveillance in Vietnam relies on underdeveloped electronic medical record (EMR) systems, which are insufficient for timely standardized data collection about craniofacial and cleft pathologies. Concurrently, the World Bank reports Vietnamese mobile cellular subscription rates (per 100 people) of 128, some of the highest in the world. Herein, we discuss the development of a short messaging service (SMS)-based surveillance system based in Hanoi, Vietnam, and its utility in contrast to an EMR-based approach to craniofacial epidemiology study.
Methods: Vietnam National Children's Hospital (VNCH) is a pediatric tertiary care center serving approximately 12 million children. Four plastic surgeons were trained in SMS data entry. The SMS database was designed using FrontlineSMS, a 2-way mobile gateway software application with automated messaging capabilities. The VNCH EMR database was queried for individual demographic data for patients seen by the department from 2010 to 2019.
Results: A corrected prevalence for cleft lip and palate of 0.098% (1 in 1020 live births) was calculated based on EMR data. Six rural provinces greater than 150 km from Hanoi were found to be significantly (P < 0.01) underserved surgically by the VNCH. A significantly (P < 0.01) higher rate of Pierre Robin in Lang Son province and facial clefts in Ha Tinh province were identified. The prospective data collection system received 7 patient data sets over 4 months, resulting in a capture rate of 2.9%.
Conclusions: This feasibility study offers valuable insight into the true cleft and craniofacial prevalence in Vietnam and alternative methods to study in low- and middle-income countries.
