Description

Requires both an access code and a totally encrypted verify code that must be changed every 90 days in order to access computer system. Requires assignment of specific menu options and specific security keys in order to access/enter donor data. Utilizes an automatic time-out algorithm and site specified time-out parameters to prevent potentially inappropriate access, in the event that an authorized user were to breach the usual security measures and leaves the CRT unattended while still signed on. Provides on-line documentation and help prompts based on the data dictionaries for the files used by the donor menu options/routines. Provides detailed data dictionaries for each file which provide all of the specific details, including name and number of the field, the global location, the type of data, etc. Additional details are provided in Appendix F that includes a detailed description of the data elements for the various files as part of the Intended Uses. Requires assignment of specific menu options and specific security keys in order to access/enter inventory/patient data. For sites which are defined as multidivisional in the INSTITUTION file (#4), requires assignment of user access by division in order to access/enter data for a specific division. For sites which are defined as multidivisional in the INSTITUTION file (#4), assigns the division of the user based on data entered during the sign-on process and uses this division for determining access as detailed in other specific SRS. For sites which are defined as multidivisional in the INSTITUTION file (#4), allows user to change divisions during a ‘session’, providing the user has the appropriate access Utilizes a variety of VA FileMan features and tools to routinely provide a < 2-second average response time between prompts. Provides an interface with a bar code reader as a peripheral device, connected in-line between the CRT and CPU via cables, which is able to read Stop Codes and Codabar symbology in accordance with the Uniform Blood Labeling Act. Provides ability for the user facilities to document the software validation performed by the site. Provides audit trail report of the changes in verified data. Note: This report requires a higher level of security to access. Restricts data entry based on the data type and the input transforms for the specific field.
