3 1. Introduction 1.1 Purpose The purpose of this Software Requirement Specifications (SRS) document is to outline the functional and nonfunctional requirements of the proposed electronic medical record system for Ruston Eye and Laser Institute. The document will give an overall description of the proposed new system and a detailed description of the new system features. 1.2 Document Conventions Unless otherwise notated, all requirements listed in this document are of high-level importance to the design of the overall system 1.3 Intended Audience Dr. Jared M. Vincent the rest of this document contains requirements for the system proposed for Ruston Eye and Laser Institute. Read the document in the order presented to gain a clear understanding of system requirements. Approach the requirements as they pertain to your system usage, paying close attention to sections dealing with physician input. Rhonda White, Business Manager the rest of this document contains requirements for the system proposed for Ruston Eye and Laser Institute. Read the document in the order presented to gain a clear understanding of system requirements. Approach the requirements as they pertain to your system usage, paying close attention to the overall system and how its parts relate to the business operations of Ruston Eye and Laser Institute. 1.4 Project Scope The Insight system proposed for Ruston Eye and Laser Institute is an all-inclusive electronic medical record storage system with capabilities for patient management, inventory control, and automatic insurance verification. As a full-featured ophthalmology clinic and optical shop, the Insight system will allow Ruston Eye and Laser Institute to expand its patient-base while experiencing increases in efficiency and decreases in cost. The system will meet needs being met by the system currently in place as well as unmet needs identified in business operations and the development of these requirements. 1.5 References The Health Insurance Portability and Accountability Act of 1996 (HIPAA) Privacy and Security Rules 1

4 The Safety and Quality Improvement Act of 2005 (PSQIA) Safety Rule 2. Overall 2.1 Product Perspective The Insight system proposed for Ruston Eye and Laser Institute is a modern iteration of the system currently utilized. 2.2 Product Features Major features of the proposed Insight system include: FE-01 Electronic medical record creation and storage FE-02 Automated insurance coverage verification FE-03 Inventory control *refer to Appendix A for Use Cases pertaining to these features 2.3 User Classes and Characteristics Physician The physician is the primary user of the system. The physician has administrator privileges and can set privileges for other employees.

5 The system will be accessed remotely over the internet, allowing use of the system from any computer with a compatible internet browser. 2.5 Design and Implementation Constraints CO-01 CO-02 CO-03 CO-04 The designed system must be able to be accessed remotely over an internet connection. Storage and encryption must be compliant with HIPAA regulations. Permissions must be set for three types of users: physician, manager, and employee. All current medical records must be able to be entered into the system. 2.6 User Documentation A comprehensive User Manual will be included with delivery of the final system. 24/7 technical support will be available through SDLC. 2.7 Assumptions AS-01 AS-02 AS-03 SDLC technical and project resources are available and have capability to define, develop, test, train, and deploy the project. Peripheral testing devices export in a graphical format that can be stored and viewed. Medical diagnosis and procedural codes cover the complete range of possible patient diagnosis and treatment. 2.8 Dependencies DE-01 DE-02 DE-03 DE-04 Wasp Inventory Control System must be purchased Updates from the Medicare system to medical diagnosis and procedural codes will be provided, allowing for system updates.
