The system is an electronic surveillance platform aimed at monitoring the health and development of children aged 0-6 years. It integrates clinical, screening, and analytical processes in a unified digital environment, allowing for the registration of child and maternal demographic and medical data. The platform facilitates the management of both scheduled and unscheduled visits, as well as the completion of age-appropriate assessment tools, including developmental questionnaires, autism screenings, and the ASQ-3 assessment instrument. It utilizes growth charts interpreted through Z-scores and automatically records perinatal risks and immunization data. Furthermore, the system is synchronized with the national birth registry for automated data updates. Supporting referral mechanisms and online appointment scheduling, specialists can document consultation outcomes directly within the platform. An integrated analytics module is capable of generating indicator-based reports and quality assessment dashboards. Overall, the system is designed to enable the early identification of developmental concerns, standardized monitoring, and timely access to appropriate healthcare services, with a focus on maternal and child health for a target population comprising children under five.
