Lecture a

Information System

• Automated system– Computer hardware and software

• Receives data• Processes data• Outputs data

– Supports the functions of the organization



Lecture a

General Characteristics of an Information System

• Inputs– Order for a drug

• Data – Prescribed drug

• Process– Verifies drug is correct for the order

• Outputs– Documentation of administration



Lecture a

Characteristics of an Information System

• Organization of data into information– Example

• Data dictionary• Ability to analyze the information

– Example• Medication management



Lecture a

Major Information System Categories

• Transaction Processing System (TPS) • Management Information System (MIS)• Decision Support System (DSS)



Lecture a

Transaction Processing System (TPS)

• Transaction Processing System (TPS)– Processes information in order to complete a

transaction• Examples:

– Admit, discharge, transfer (ADT)– Patient billing



Lecture a

Admission-Discharge-Transfer (ADT)

“The name given to software systems used in health care facilities that register and track patients from admission through discharge including transfers; usually interfaced with other systems used throughout a facility such as an electronic health record or lab information system.”



Lecture a

Management Information System (MIS)

• Management Information System (MIS)– Helps managers plan, organize, and evaluate

their department• Examples:

– Laboratory department– Emergency department



Lecture a

Emergency Department Information Systems

• Dashboard systems• Communication systems• Clinical decision support • Documentation systems• Computerized training and information retrieval• Systems to facilitate public health surveillance



Lecture a

Decision Support System (DSS)

• Information system – Gathers data from a variety of sources– Assists in providing structure to the data– Facilitates and improves the outcome of

business and organizational decision-making activities

• Example:– Clinical DSS



Lecture a

Health Care Information System (HCIS)

• Information system used within a health care organization – Facilitates communication– Integrates information– Documents health care interventions– Performs record keeping – Otherwise support the functions of the

organization



Lecture a

HCIS Components

• Patient management and billing• Department management• Care delivery and clinical documentation• Clinical decision support • Financial and resource management



Lecture a

Patient Management and Billing• Systems that support the management of the

patient – Example

• Patient identification– Supporting technology

• Master patient index– Patient-identifying directory– Links to the patient record– Facilitates patient identification– Assists in maintaining a longitudinal patient record



Lecture a

Department Management

• Systems that support a department’s information needs– Example

• Health Information Management Department Systems

– Supporting technology• Electronic Document Management Systems

• Supplies data to patient databases



Lecture a

Care Delivery and Clinical Documentation

• Systems that support the delivery of the care and documentation of that care– Example

• Clinical information systems– Supporting technology

• Clinical documentation• Houses patient clinical data



Lecture a

Clinical Decision Support

• Systems that support the clinical staff with data interpretation and decision-making– Example

• Prescription decision support– Supporting technology

• Drug-drug interactions• Accesses patient clinical data



Lecture a

Financial and Resource Management

• Systems that support business functions– Example

• Accounts Payable System– Supporting technology

• Claims administration• Houses financial and employee data



Lecture a

Practice Management

• Practice management system (PMS)– Combination of financial and administrative

functions– Patient appointment, scheduling, registration,

billing, and payroll functions• PMS and electronic medical records integration



Lecture a


Summary – Lecture a• Definition of an information system and its

characteristics• Types of information systems that support the

health care enterprise requirements• Types of technologies that support health care

information systems
