What Is a Hospital Information System (HIS)? Modules, Benefits & Applications
Introduction
Healthcare organizations generate information across clinical care, appointments, diagnostics, billing, patient services, facilities and administration.
A Hospital Information System brings many of these activities into a connected digital environment.
The World Health Organization describes health information systems as important for collecting, analysing and using health information, while hospital information systems can support clinical and internal management activities.
What Is a Hospital Information System?
A Hospital Information System, or HIS, is a digital system designed to manage and connect information and workflows across hospital operations.
Depending on the system, this can include:
- Patient management
- Appointment scheduling
- Electronic medical records
- Prescriptions
- Billing
- Inpatient management
- Diagnostics
- Laboratory workflows
- Patient engagement
- Staff management
- Reporting and analytics
Key Modules of a Hospital Information System
A connected HIS can bring multiple functions into a common digital environment.
Patient Management
Supports registration, patient information and related administrative workflows.
Appointment & Scheduling
Helps coordinate appointments and healthcare resources.
EMR/EHR Clinical Notes
Provides digital clinical documentation and patient information management.
Prescriptions & Medication Management
Supports prescription and medication-related workflows.
Billing & Revenue Cycle Management
Connects billing activities with relevant patient and service information.
Diagnostics & Lab Management
Supports diagnostic and laboratory workflows.
Patient Portal & Engagement
Provides digital channels for patient interaction and access to relevant information.
Reports & Analytics
Transforms operational and clinical data into reports and analytical views.
Why HIS Matters
A connected information environment can help reduce fragmentation between different hospital functions.
WHO notes that effective health information systems support health-service management, decision-making, data use and coordination across healthcare environments.
HIS and Interoperability
Modern healthcare environments increasingly require systems to exchange information across applications and organizations.
Interoperability is therefore an important consideration when evaluating healthcare technology.
