There are two methods of installation of WorldVista EHR:

1. Step-by-Step installation of a basic version of EHR
2. Self installing versions of WorldVista EHR

Step-by-Step Installation

• Decide on whether you will implement a Windows or Linux based system.

     There are two server platform options, either Linux, which provides a full open source stack using Fidelity's GT.M database and one of the popular Linux distributions
     Or the MS Windows server which will require obtaining a Cache database license and software from Intersystems Corporation.

• Download and install a copy of the appropriate server software.

     Make sure you download and read the Readme file first as it contains the password needed to un-zip the server software file.

• Download and install the basic client software components.

• The server and client software can be obtained by clicking on the following links:

WorldVista-Clinical Features Overview

The main interface of WorldVista is called "CPRS"-from which derived the "CIS" of OpenVista. It is the short form for "Computerized Patient Record System". CPRS looks unattractive but robust inside. It is a window one sees after logging in to the system which provide access to patient details. The "CIS" provides two ways to start working....one by 'selecting patients'....Patient wise and the second way is by 'a list of Notifications'. Going either way takes to a window with all available Patient Information. It has tabs at the bottom to view the data in the following categories.

1. Coversheet
2. Problems
3. Meds
4. Orders
5. Notes
6. Consults
7. Surgeries
8. Discharge Summary
9. Lab Results
10. Reports

A seperate Vitals tabs is present in OpenVista in addition to the above.

Coversheet

It also shows important information about the important Clinical Reminders, the current patient's allergies, behavior in the form of Alerts, Postings and Flags. The details about a particular data can be viewed in an elaborated way selecting the tabs. Alerts and Postings can be accessed from any tab view.

Problems

Discharge Summary

This tab contains the discharge summary of the patient.

Labs

Conclusion

Though WorldVista looks non-attractive, it is time tested and worked without flaws for VA-hospitals. It is difficult to configure WorldVista but new EHRs developed based on WorldVista like OpenVista are promising new developments.
