NEED FOR LIS

RADIOLOGY INFORMATION SYSTEM

INTRODUCTION:

RIS is an electronic web based application designed with high flexibility and ease of usage , implemented in single clinics and polyclinics. RIS is a complete management system that handles all the business functions from patient management , diagnosis to inventory control.

RIS makes information immediate , easy to access , easy to update and always available for those who need to know.

Functions:

Order requestRegistrationExaminationResults reporting Work list preparationResults approvalAppointment schedulingManagement system

Objectives:The RIS is a means for E healthcare that facilitates management of the workflow of radiology services and equipments , in addition to supporting entry of work records and reports

The ultimate objective is to store all patient images , scans and ECG graphs or as electronic files due to its integration with PACS , thus eliminating retrieval and dissemination of film

Specific Objectives:

1.Establishment of paperless environment while maintaining digital recording.

2.Optimize radiology resources and streamline workflow.

3.Increase efficiency of medical care outcome.

Functionality :

1.Integration with the Master Patient Index.2.Integration with the Appointment system.3.Integration with the inventory system.4.Integration with the clinician.5.Integration with the order management.

WORK FLOW

Picture Archiving and Communication System (PACS) A system capable of acquiring, transmitting,

storing, retrieving, and displaying digital images and relevant patient data from various imaging sources, and capable of communicating the information over a network

Depends on interfaces to other medical information systems, such as the Radiology Information System (RIS)

Digital Imaging and Communications in Medicine (DICOM) An international standard (ISO) describing how

radiology images are identified and formatted and how imaging devices communicate with each other

Jointly developed by the American College of Radiology and the National Electronic Manufacturers Association

Based on the ISO Open Standards Intercommunications (OSI) model

http://dicom.nema.org/

A PACS can accept any image that is in digital imaging and communications in medicine (DICOM) format, for which it is set up to receive, whether it is from cardiology, radiology, or pathology. A PACS serves as the fileroom, reading room, duplicator, and courier. It can provide image access to multiple users at the same time, on-demand images, electronic annotation of images, and specialty image processing.

ADVANTAGES OF PACS:

• Elimination of less efficient traditional film libraries and their inherent problem of physical space requirements for hard-copy images

• Convenient search for and retrieval of images

• Rapid (electronic) transfer of images within the hospital (e.g., clinics, operating rooms, treatment units)

Simultaneous viewing of images at multiple locations

• Elimination of misplaced, damaged, or missing films

• Increase in efficiency of reporting exams with soft-copy images (compared with hard-copy images)

•

Reduction of the health and environmental impact associated with chemical processing, as a result of decreased use

Ease in consulting outside specialists—teleradiology. Teleradiography is the electronic transmission of diagnostic images from one location to another for purposes of interpretation and/or consultation.

Examples of errors within and between PACS components Acquisition errors

Improper technique selection

Wrong exam performed

Image deleted Network errors

Image lost Image corrupted Unable to transmit

Archive errors Storage media

corrupted Storage failure Sequestered exams

Display errors Mis-calibration Associated data not

displayed Artificial shutters

Sources of Errors in PACS

Mistakes in configuration of PACS Improper calibration of PACS devices Discrepancies between PACS and hospital

processes PACS design flaws Inherent limitations of human operators Inadequate training and documentation of PACS

and hospital processes Insufficient planning for PACS service
