Abstract
BACKGROUND: The Bureau of Vector-borne Diseases, Ministry of Public Health,
Thailand, has implemented an electronic Malaria Information System (eMIS) as part
of a strategy to contain artemisinin resistance. The attempt corresponds to the
WHO initiative, funded by the Bill & Melinda Gates Foundation, to contain
anti-malarial drug resistance in Southeast Asia. The main objective of this study
was to demonstrate the eMIS' functionality and outputs after implementation for
use in the Thailand artemisinin-resistance containment project.
METHODS: The eMIS had been functioning since 2009 in seven Thai-Cambodian border
provinces. The eMIS has covered 61 malaria posts/clinics, 27 Vector-borne Disease
Units covering 12,508 hamlets at risk of malaria infections. The eMIS was
designed as an evidence-based and near real-time system to capture data for early
case detection, intensive case investigation, monitoring drug compliance and
on/off-site tracking of malarial patients, as well as collecting data indicating
potential drug resistance among patients. Data captured by the eMIS in 2008-2011
were extracted and presented.
RESULTS: The core functionalities of the eMIS have been utilized by malaria staff
at all levels, from local operational units to ministerial management. The eMIS
case detection module suggested decreasing trends during 2009-2011; the number of
malaria cases detected in the project areas over the years studied were 3818,
2695, and 2566, with sero-positive rates of 1.24, 0.98, and 1.16%, respectively.
The eMIS case investigation module revealed different trends in weekly Plasmodium
falciparum case numbers, when classified by responsible operational unit, local
and migrant status, and case-detection type. It was shown that most Thai patients
were infected within their own residential district, while migrants were infected
either at their working village or from across the border. The data mapped in the
system suggested that P. falciparum-infected cases and potential drug-resistant
cases were scattered mostly along the border villages. The mobile technology
application has detected different follow-up rates, with particularly low rates
among seasonal and cross-border migrants.
CONCLUSION: The eMIS demonstrated that it could capture essential data from
individual malaria cases at local operational units, while effectively being used
for situation and trend analysis at upper-management levels. The system provides
evidence-based information that could contribute to the control and containment
of resistant parasites. Currently, the eMIS is expanding beyond the
Thai-Cambodian project areas to the provinces that lie along the Thai-Myanmar
border.
