The HMS Base Module is the essential core and starting point for any medical facility looking to digitize its operations on Odoo. It establishes the central data models that all other healthcare modules will depend on—including the master Patient Record, Practitioner/Doctor Directory, and core configurations like medical departments. By providing a unified, developer-friendly architecture, this base module ensures that every subsequent app you install—from Laboratory and Pharmacy to In-Patient and Billing—shares the same central nervous system, guaranteeing data consistency and seamless integration across your entire hospital.
