A complete Hospital Information System designed by a medical doctor, engineered for real hospital workflows. Trusted by 40+ institutions, running 22 years of continuous development, and publicly verifiable on GitHub.
CareCode HMIS was initiated in 2004 by Dr M H B Ariyaratne — an MBBS, MSc (Biomedical Informatics), MD (Health Informatics) — who built the first version for his own clinical practice because no available system did the job well enough.
What began as a single-GP EMR grew over two decades into a full Hospital Enterprise Resource Planning system covering every clinical, operational, and financial domain of a modern private hospital. Every workflow in the system was designed by someone who has personally worked in OPD, Obstetrics & Gynaecology, and Radiology.
The system carries an MIT open-source licence. Its entire development history — 48,000+ commits — is publicly visible and auditable on GitHub.
