Development of Web Application to Support Dengue Investigation Team of Communicable Disease Control Operations Unit in Phang Nga Province

Abstract

Phang Nga Province in Thailand continues to face persistent challenges related to Dengue Hemorrhagic Fever (DHF) and associated fatalities. In response to the limitations of existing paper-based systems in managing dengue fever data effectively, this study aims to develop a web application to support the Dengue Investigation Team within the Communicable Disease Control Operations Unit in Phang Nga Province. The research engaged 22 stakeholders, including public health officers, data managers, and field investigators, who participated in a stakeholder analysis process to identify user requirements that would inform the design and development phases. Utilizing Agile Software Development Lifecycle (SDLC) methodologies, the web application was developed using MySQL for database management and PHP for web service programming. The resulting web application includes functionalities for data collection and a stakeholder dashboard for statistical analysis. Testing and evaluation were conducted using satisfaction scales, which yielded high satisfaction scores (mean ± SD) across functionality, usability, and accessibility. Stakeholder feedback indicated the need for additional features to enhance data collection, analysis, and integration of information across healthcare facilities. The evaluation results highlight the application's potential to address public health challenges and support the Dengue Investigation Team in combatting dengue fever in the region. Currently, the application is in the pilot testing phase, and further refinement is necessary to improve data integration and security measures. This research contributes to advancing disease surveillance and control measures, emphasizing the importance of continuous refinement to meet evolving user needs and ensure a lasting impact on public health.
