Mump surveillance evaluation at Chaiprakarn Hospital, Chiangmai Province, Thailand during 2013-2018

Abstract

Backgrounds: Background: Mumps is one of the most contagious infectious disease under surveillance in Thailand. Incidence of Mumps in Thailand was declined over the past 10 years. However, in 2018, Chiang Mai Province had 2nd highest incidence in Thailand (7.81 per 100,000 popular) and Chaiprakarn District had the highest incidence in Chiang Mai (76.26 per 100,000 popular). The objectives of this study were to describe Mumps surveillance in Chaiprakarn District, study quantitative and qualitative characteristics, and provide recommendations to improve the system.
Methods: We described surveillance quantitatively and qualitatively by reviewing medical records of patients who received treatment at Chaiprakarn Hospital from 1st January 2013 to 31st December 2018 and met with diagnostic criteria of Mumps. We compared data with reported cases under surveillance from the same period.
Results: Sensitivity of this surveillance was 54.16% because they reported only cases who diagnosed by physician instead of using disease surveillance definition. Positive predicative value and data quality was good (100%). Reported data could be represented in age, monthly classification, and morbidity rate classified by area. Timeliness was 69.39%, because there was only one staff in District Public Health Office responsible for reporting data. Results from qualitative study shown that system was simple and flexible. Officers accepted and recognized how importance of monitoring situation of Mumps cases. Chaiprakarn District also used information from Mump surveillance to analyze and provide recommendations for public health measurements.
Conclusion and Discussion: Providing knowledge and reviewing guidelines will allow staff to understand and work more efficiently, accurately and completely. Hospital guidelines should be revised base on surveillance definition. Duration of investigation after reported should be defined for timely prevention and control of outbreak. There should be summarized of epidemiological information and shared to stakeholders and community regularly.
