Abstract
BACKGROUND: Dengue fever is a significant public health problem in Thailand. There is a seasonal outbreak pattern that can be found throughout the year. Thus, an effective surveillance system is required. The situation of the COVID-19 pandemic has impacted the strength of disease surveillance. Therefore, the disease surveillance system was evaluated to check whether the system remains strengthened.
OBJECTIVES: To study the disease reporting process of the surveillance system, quantitative and qualitative characteristics were evaluated, and ways to develop the dengue fever surveillance system were determined.
METHODS: A cross-sectional descriptive approach was used by reviewing the medical records of patients who were diagnosed with dengue fever and similar disease groups from 1 January to 31 December 2022 and interviewing personnel via the created questionnaire. The data were analyzed using descriptive statistics and content analysis.
RESULTS: A total of 91 patients met the disease criteria, and 60 patients were reported in the surveillance system. It was found that the sensitivity of disease diagnosis was 65.9% and the accuracy of disease reporting or predictive positive value was 95.2%. The information in the surveillance system was recorded completely at 100%. The gender and age variables were correct at 100%, while the address at the time of illness was correct at 82.5%, and the date of illness onset was correct at 63.5%. The reporting data matched and could be representative. Cases were reported in a timely manner. Executives accepted and gave importance to using data to continuously monitor and supervise work. The staff understood the system and had backup staff. Disease codes were updated according to defined provisions. The hospital had a patient care system during official time, out time and emergency. The budget was sufficient.
CONCLUSIONS: The surveillance system reporting process follows provincial guidelines. All quantitative and qualitative characteristics were within acceptable limits. The results of the study could be used to develop the strength of disease surveillance, prevention and control in the area.
