Electronic Medical Records System

EMR Custom Development

A structured, secure digital record of each patient’s history, diagnoses, medications, allergies, results and clinical notes, available to authorised clinicians at the point of care.

Overview

Electronic Medical Records System (EMR)

Good clinical decisions depend on a complete history. An Electronic Medical Records System replaces paper files with a structured digital record that follows the patient across visits and departments: problems and diagnoses, medications, allergies, vital signs, results, procedures and clinicians’ notes, all in one chronological view.

Extrion Tech designs and develops EMR systems in-house for hospitals, clinics and programmes in Zanzibar and Tanzania. We work with clinicians to define the forms they actually need – general consultation, antenatal, chronic disease follow-up, paediatrics – using standard coding such as ICD-10 where the client requires it. The EMR can stand alone or sit alongside billing, laboratory and pharmacy systems through APIs, according to project scope.

Because medical records are among the most sensitive data an organisation holds, access is granted by role and care relationship, every view and change is logged, and records are never silently overwritten. Clinical alerts for allergies and drug interactions can be configured. Privacy safeguards, consent handling and retention periods are agreed with the client for the relevant jurisdiction before the system goes live.

Business problems it addresses

  • Clinicians treat patients without seeing previous diagnoses, allergies or medications.
  • Paper files are bulky, deteriorate and cannot be read by more than one person at a time.
  • Handwritten notes are hard to read and lead to medication and dosage errors.
  • Chronic patients’ progress cannot be tracked over time to judge whether treatment works.

Workflow

Building the patient record

  1. 1

    Identify the patient

    The clinician opens the correct record using hospital number, name and date of birth checks.

  2. 2

    Review the summary

    Active problems, medications, allergies and recent results are shown before anything is entered.

  3. 3

    Document the encounter

    History, examination and vital signs are recorded on the form suited to the visit type.

  4. 4

    Diagnose and code

    Diagnoses are added with ICD-10 codes and the problem list is updated.

  5. 5

    Order and prescribe

    Investigations and medicines are ordered, with allergy and interaction alerts checked.

  6. 6

    Sign the note

    The clinician signs the encounter, locking it; later changes become dated addenda.

  7. 7

    Continuity of care

    Referrals, follow-up plans and results stay on the timeline for the next clinician.

Functions covered

Modules and what they do

01 Patient record

  • Patient summary

    Shows demographics, active problems, medications, allergies and alerts on one page.

  • Clinical timeline

    Lists every encounter, result and procedure in date order.

  • Document scanning Optional / subject to scope

    Attaches scanned historical files and external reports to the record.

02 Clinical documentation

  • Encounter forms

    Provides structured forms for consultation, antenatal, chronic care and other visit types.

  • Diagnosis coding

    Records diagnoses with ICD-10 codes for clinical and statistical use.

  • Medication management

    Records prescriptions and maintains the current medication list.

  • Clinical alerts Optional / subject to scope

    Warns about allergies, duplicates and configured drug interactions.

03 Care coordination

  • Orders and results

    Sends lab and imaging orders and files returned results in the record.

  • Referrals

    Creates referral letters and tracks referred-in and referred-out patients.

  • Chronic care registers Optional / subject to scope

    Tracks patients with conditions such as diabetes or hypertension over time.

04 Governance

  • Access and consent

    Controls who may view records and records consent or restricted-access flags.

  • Data exchange Optional / subject to scope

    Shares records with other systems through APIs, using HL7 FHIR where scoped.

Security & data integrity

Protecting your data and its accuracy

Every record view, edit and export is logged against the user, and sensitive records can be flagged for restricted access. Consent, privacy safeguards and retention periods are agreed with the client for the relevant jurisdiction.

Standard protections

  • Role-based access control

    Each user sees only what their role allows.

  • Authentication and authorisation

    Every request is checked for a signed-in, permitted user.

  • Fine-grained permissions

    Permissions per module and action, such as view, edit or approve.

  • Secure password storage

    Passwords are stored using strong one-way hashing, never in plain text.

  • Encryption in transit

    HTTPS/TLS protects data between users and the server.

  • Encryption at rest

    Sensitive data encrypted on disk where the infrastructure supports and is configured for it.

  • Server-side input validation

    All input is validated on the server before it is saved.

  • Protection against common web vulnerabilities

    Defences against injection, cross-site scripting and request forgery.

  • Database constraints and transactions

    Constraints and transactions keep related records consistent.

  • Audit logs

    Important actions are recorded with who, what and when.

  • User activity history

    A history of each user’s activity for supervisors and administrators.

  • Backup and restoration

    Scheduled backups with tested restoration procedures.

  • Session management

    Session time-outs and the ability to sign out other devices.

  • Data retention and deletion policies

    Retention periods and deletion rules agreed with you.

Optional advanced protections

  • Multi-factor authentication A second sign-in step for selected or all users.
  • Single sign-on Sign in with your organisation’s identity provider where supported.
  • Disaster recovery planning A documented plan to restore service after a major failure.
  • Offline mode with controlled synchronisation Work offline and synchronise safely when the connection returns.
  • Data export controls Exports limited to authorised roles and recorded.

Data integrity

Patient identity checks and duplicate detection prevent records being split or merged by mistake. Signed encounters are immutable, so corrections are added as dated addenda that preserve the original, and coded fields are validated against controlled lists such as ICD-10.

Security controls are configured for each project. We do not claim certification, compliance or immunity from attack unless independently verified for your deployment.
