Self-Hosting for Medical Clinics

Medical clinics operate under confidentiality requirements that no other business faces. Patient records are legally protected. Data breaches at medical practices can result in regulatory penalties, professional discipline, and loss of patient trust. Self-hosting keeps patient data on hardware the clinic controls, under the clinic's security policies, accessible only to authorised staff.

The Stack

• Electronic medical records: OpenEMR (free, open-source). Full EMR with patient demographics, medical history, prescriptions, lab results, and billing. ONC certified in the United States. Supports custom forms for Brunei-specific medical documentation.
• Practice management and billing: OpenEMR includes billing and insurance modules. For standalone billing, ERPNext or Invoice Ninja handle patient invoicing and payment tracking.
• Document management: Paperless-ngx for digitising paper records, lab reports, referral letters, and consent forms. OCR makes every document searchable.
• Appointment scheduling: OpenEMR includes a patient portal with online appointment booking. Patients book their own appointments, reducing phone call volume for reception staff.
• Email and communication: Docker Mailserver for clinic email. End-to-end encrypted communication with patients is possible through platform-specific secure messaging, but standard email with TLS is the practical baseline for appointment reminders and test result notifications.
• Internal communication: Mattermost for staff communication. Separate channels for doctors, nurses, and administrative staff. Instant messaging without patient data leaving the clinic's server.

Why OpenEMR Over a Commercial EMR

Commercial EMR systems charge per provider per month. A clinic with three doctors might pay 500 to 1,000 US dollars per month in EMR licensing alone. OpenEMR is free and open-source. It is ONC certified, meaning it meets US federal standards for electronic health records. It supports e-prescribing, lab integration, clinical decision support, and patient portals. The certification is US-based, but the software is used internationally and can be configured for local medical documentation standards.

The learning curve for OpenEMR is real. It is a professional medical tool, not a consumer app. Staff need training. But once configured, it handles patient records, appointments, billing, and clinical notes in one system that the clinic owns and controls.

Patient Data Security

Medical data security is not optional. The minimum requirements for a self-hosted clinic stack:

• Encryption at rest: The server disk is encrypted. If the physical server is stolen, the data is unreadable.
• Encryption in transit: All connections use HTTPS with modern TLS. Patients accessing the portal do so over an encrypted connection.
• Access controls: Authelia provides single sign-on with granular permissions. Reception staff see appointment data but not clinical notes. Doctors see clinical notes and patient history. Administrators see billing but not medical records.
• Audit logging: Every access to patient records is logged. The audit trail shows who accessed which record, when, and from which IP address. This is essential for compliance and for investigating potential breaches.
• Backups with retention: Medical records must be retained for years, sometimes decades. Automated, encrypted, offsite backups with documented retention policies meet this requirement.
• No third-party access: The data is on the clinic's server. No cloud provider, no EMR vendor, no SaaS platform has access. The clinic controls encryption keys, access policies, and backup locations.

Patient Portal

OpenEMR's patient portal lets patients book appointments, view test results, request prescription refills, and message their doctor. This reduces phone calls and gives patients convenience without requiring staff to relay information. The portal runs on the clinic's server, so patient portal data is subject to the same security controls as the EMR itself.

VPS1 builds secure, compliant stacks for medical clinics. We deploy OpenEMR with encryption, access controls, audit logging, and backups. Patient data stays where it belongs: on your hardware, under your control.
