HCIS — DOHIS Platform

Overview

DOHIS (Department of Health Information System) is a centralized platform replacing Bangkok Metropolitan Administration's (BMA) legacy HCIS for the Department of Health, serving public health services across Bangkok's district health centers (ศบส.).

The system is a mono-repo housing 6 sub-applications — from OPD to telemedicine, GIS, PDPA compliance, and drug inventory — backed by Go microservices deployed on Kubernetes via ArgoCD GitOps.
