HEALTH INFORMATION

SYSTEM DESIGN

USE OF INFORMATION

SYSTEMS IN MANAGING

• HEALTH INFORMATIONINFORMATION SYSTEMAn information system is a set of interconnected

components that work together to collect, process, store, and distribute information to support decisionmaking, coordination, control, analysis, and visualization in an organization.

• Information systems play a vital role in managing and
• leveraging information to achieve business goals and
• objectives. These systems are designed to handle data
• in various forms and provide valuable insights for
• users at different levels within an organization.COMPONENTS OF AN
• INFORMATION SYSTEMPeople: Users who interact with the system, including
• those who input data, manage the system, and use
• information for decision-making.
• Data: Raw facts and figures are processed to create
• meaningful information. Data can be structured
• (organized in a specific format, like a database) or
• unstructured (e.g., text, images, audio).
• Processes: Procedures and algorithms that
• manipulate and process data to generate information.
• This includes data entry, storage, retrieval, and
• analysis.Information Technology (IT): Hardware and
• software components that enable the functioning
• of the information system. This includes computers,
• servers, networks, databases, and software
• applications.
• Communication Channels: Systems and networks
• that facilitate the flow of information within and
• between organizations. This includes internet
• connections, intranets, and communication

protocols.CATEGORIES OF

INFORMATION SYSTEMS

BASED ON THEIR SCOPE

• AND FUNCTIONSTransaction Processing Systems (TPS)
• Record and process day-to-day transactions of an
• organization, such as sales, purchases, and
• inventory changes.
• Management Information Systems (MIS)
• Provide summarized, structured information to
• support managerial decision-making. MIS typically
• produce regular reports and summaries.Decision Support Systems (DSS)
• Assist in decision-making at the management
• level by providing interactive and ad-hoc
• reports, analysis tools, and modeling
• capabilities.
• Executive Information Systems (EIS)
• Serve top-level executives by providing strategic
• information and key performance indicators
• (KPIs) for high-level decision-making.Enterprise Resource Planning (ERP) Systems
• Integrate various business processes and
• functions across an organization, facilitating
• seamless information flow and improving
• efficiency.
• Knowledge Management Systems (KMS)

Capture, organize, and apply the collective knowledge and expertise within an organization.Customer Relationship Management (CRM) Systems Manage interactions with customers, streamline sales and marketing processes, and enhance customer service.

• Geographic Information Systems (GIS)
• Capture, analyze, and display spatial or geographic
• data, supporting decision-making related to locations

and spatial relationships.COMMON TYPES OF

HEALTH INFORMATION

• SYSTEMSElectronic Health Records (EHRs)
• Comprehensive digital records that contain a
• patient's health information, including medical
• history, diagnoses, medications, allergies,
• immunization status, and test results.
• Purpose: Facilitate secure sharing of patient
• information among healthcare providers and
• enhance overall care coordination.Health Information Exchange (HIE) Systems
• Platforms that enable the electronic sharing of
• patient information among different healthcare
• organizations, such as hospitals, clinics, and
• laboratories.
• Purpose: Support continuity of care, reduce
• redundant tests, and improve collaboration among
• healthcare providers.Picture Archiving and Communication
• System (PACS)
• Systems that manage and store medical images, such
• as X-rays, MRIs, and CT scans, in a digital format. PACS
• allows for the retrieval, distribution, and
• interpretation of these images.
• Purpose: Enhance collaboration among radiologists
• and other specialists, improve diagnostic processes,
• and reduce the need for physical film.Laboratory Information System (LIS)
• Systems that manage and store information
• related to laboratory tests, including sample
• processing, results, and quality control.
• Purpose: Streamline laboratory workflows,
• improve accuracy, and facilitate the timely
• reporting of test results.Radiology Information System (RIS)
• Systems designed specifically for managing
• radiology workflows, including scheduling,
• tracking, and reporting on radiological
• procedures and images.
• Purpose: Enhance the efficiency of radiology
• departments, improve communication, and
• ensure proper tracking of imaging studies.Pharmacy Information System
• Systems that manage and automate pharmacyrelated processes, including medication
• dispensing, inventory management, and
• prescription processing.
• Purpose: Improve medication safety, reduce
• errors, and streamline pharmacy operations.Telehealth and Telemedicine Systems
• Platforms that use information and communication
• technologies to provide healthcare services
• remotely. This includes virtual consultations,
• remote monitoring, and telehealth applications.
• Purpose: Increase accessibility to healthcare
• services, especially in remote areas, and support
• remote patient monitoring and virtual care.Clinical Decision Support Systems (CDSS)
• Software applications that provide healthcare
• professionals with information and
• recommendations to aid clinical decision-making.
• Purpose: Improve diagnostic accuracy, guide
• treatment decisions, and enhance patient care
• through evidence-based guidance.Public Health Information Systems
• Systems that support public health initiatives,
• including disease surveillance, outbreak
• tracking, and health promotion programs.
• Purpose: Facilitate the collection, analysis, and
• dissemination of public health data for effective

disease prevention and control.Health Analytics and Business

Intelligence Systems

• Systems that use data analytics tools to derive
• insights from large healthcare datasets, supporting
• population health management and performance
• improvement.
• Purpose: Enable evidence-based decision-making,
• identify trends, and improve the overall quality and

efficiency of healthcare services.FUNCTIONS OF HEALTH

Monitoring

• Security and Privacy ManagementCONCEPT OF DHIS2DHIS2, which stands for District Health Information
• Software 2, is an open-source software platform
• designed for the collection, management, analysis,
• and visualization of health data.
• It is specifically tailored for the health sector and is
• widely used by governments, non-governmental

organizations (NGOs), and international agencies for health information management.HISTORY OF DHIS2The original DHIS, the predecessor to DHIS2, was developed in the late 1980s and early 1990s. It emerged as a tool for health information management at the district level, particularly in low- and middle-income countries.

• In the early 2000s, efforts were made to transition
• DHIS from a standalone desktop applications to a
• web-based platform. This shift aimed to improve
• accessibility, usability, and scalability.CONT…
• The development of DHIS2 began around 2004 under
• the leadership of the Health Information Systems
• Programme (HISP) at the University of Oslo in Norway.

The project was initiated by Dr. Jørn Braa and Dr.

Morten Hertzum.

• As an open-source project, DHIS2 continues to
• undergo ongoing development. Regular updates and
• releases introduce new features, improvements, and
• bug fixes to address the evolving needs of the global
• health community.FEATURES AND
