Surveillance Evaluation of Hand Foot Mouth and Enterovirus Infection Diseases, Surin Province, 2016

Abstract

Hand-foot-and-mouth disease(HFMD) and disease from enterovirus Infection have been
classi ed as noti able diseases under the national surveillance in Thailand since 2001. Each year,
Thailand has a large number of patients and there are patients with severe illness and death. In Surin
province, the incidence rate of HFMD tended to increase. Surin Health Provincial Office and
The Of f ice of Disease Prevention and Control 9, Nakhon Ratchasima collaborated to Surveillance
Evaluation of HFMD and Enterovirus infection in Surin Province, 2016. The objective was to study
the quantitative and qualitative attributes of the surveillance system, the reporting process and provide
suggestions on improving the surveillance system. A cross-sectional study was conducted. We studied
in Surin hospital, Prasat hospital, Kapchoeng hospital, Thatoom hospital and Sangkha hospital.
The study population consisted of patients who were hospitalized in Surin province, aged less than
15 years from 1 January to 31 December 2016. The sample consisted of patients who were admitted
to hospital aged less than 15 years from 1 January to 31 December 2016. Searched for HFMD
and enterovirus Infection from patient records and reports from the National Noti cation Disease
Surveillance (R506). From the ve hospitals, we reviewed 1,058 medical records, and interviewed
33 health personnel. The system had positive predictive value of 50.4%, sensitivity of 61.4% for
these two diseases. The accuracy of the information was 99.6% for gender, 99.8% for age, and
48.2% for onset date. The timeliness of the reporting within 3 days was 92.9%. Information in the
medical records and in the R506 reports was in the same direction. Most patients were 0-3 years old,
high number of cases in June-August. In addition, administrators and practitioners have a positive
attitude toward the surveillance system. In conclusion, the positive predictive value and sensitivity were
at moderate level. Timeliness in reporting is good. Data from the surveillance system could represent
the medical records. The program was simple and allowed easy operation of the system. Information
from the surveillance system was used to alert the network, monitor the situation and plan
for disease control. So that the surveillance system more effective, the ow chart of the province should
be updated for the new staff can understand the work process. Samples should be sent to isolate
the causative organism. In the border hospital, there is also a problem of informing foreign patients
about the situation in the neighboring countries. It is necessary to have process for the prevention
and control of the disease not to spread to Thailand.
