  • Insurance and referral details
  • Emergency and OPD registration
  • Demographic data (age, sex, address, contact)

Importance:

  • First point of data entry
  • Forms the basis for all other modules
  • Ensures patient traceability and continuity of care

Laboratory (Lab Tests) Module

·       To manage laboratory tests from ordering to results.

Features:

  • Test requisition and scheduling
  • Barcode generation for samples
  • Workflow management (collection → testing → validation)
  • Lab result entry and electronic reporting
  • Critical alert system
  • Interfacing with laboratory equipment (LIS integration)

Importance:

  • Reduces errors in test management
  • Provides timely and accurate lab results
  • Facilitates data-based diagnostics

Radiology Module

·       To handle all diagnostic imaging orders and reports.

Features:

  • Request generation for X-rays, CT, MRI, USG, etc.
  • PACS (Picture Archiving and Communication System) integration
  • Radiologist reporting
  • Image storage and retrieval
  • Report validation and e-signature

Importance:

  • Digital access to imaging reports
  • Reduces turnaround time
  • Integration with EMR/EHR for clinical decision-making

Pharmacy Module

·       To manage drug inventory, prescription, and dispensing.

Features:

  • Drug formulary and stock management
  • Prescription from doctors (e-prescription)
  • Drug interactions and allergy checks
  • Billing and insurance integration

Features:

  • Fast-track patient registration
  • Triage classification (Red, Yellow, Green)
  • Emergency case documentation
  • Vital sign monitoring and quick orders
  • Integration with radiology, lab, and pharmacy
  • Emergency alert protocols and notifications

Importance:

  • Enables rapid decision-making
  • Saves lives by reducing delays
  • Tracks medico-legal cases

Discharge Summary Module

·       To generate a comprehensive report at the end of hospitalization.

Features:

  • Auto-pull of data from treatment records
  • Diagnosis, treatment, investigations, and progress notes
  • Final advice and follow-up instructions
  • Auto-formatting and customizable templates
  • E-signature and patient printout

Importance:

  • Provides continuity of care post-discharge
  • Legally required document
  • Useful for insurance and referral

Forms Module

·       To manage all hospital and patient-related forms electronically.

Features:

  • Consent forms (surgery, anesthesia, transfusion, etc.)
  • Admission and discharge forms
  • Feedback and incident reporting forms
  • Customizable templates
  • Digital signature and archiving

Importance:

  • Reduces paperwork
  • Ensures proper documentation and compliance
  • Easily retrievable for audits and medico-legal needs

Integration Across Modules

All modules are designed to interconnect, allowing for:

  • Real-time updates and alerts
  • Smooth clinical workflows
  • Enhanced patient safety
  • Better administrative control

Benefits of Modular HIS Design

  • Flexibility in implementation
  • Department-wise scalability
  • Efficient data sharing
  • Easy upgrades and customization
  • Improved decision support and analytics
