HIS FINALS Module 4 Components of an LIS Flashcards
(89 cards)
it determines how the user will interact with the system
LIS software user interface
It will have specific screens for entering data, sending reports, reporting results, etc. The software will have features such as security, access control, file maintenance, etc.

User Interface
request entry
when can requests be entered when the patient arrives at the laboratory.
In cases of outpatient
between an LIS and a clinical instrument allow automatic transfer of patient test results to the LIS.
Electronic data interface (EDI) connections
Laboratory scientist enters patient results at a client
Manual data entry
The results are added to the LIS, but they are not released to clients outside the laboratory until the results and quality control are reviewed and verified
release patient results
In this case, the computer uses a set of instructions to determine if the results should be released.
Autoverification in release patient results
Portable laboratory instruments, like handheld analyzers, can connect to an LIS via a wireless connection.
point of care testing
the Food and Drug Administration regulates LISs, and they are required to have mirrored hard drives. Data are stored on two separate hard drives of the LIS server.
redundant arrays od independent disks
Data are stored on two separate hard drives of the LIS server.
RAID
Each day, the data are to be copied to a tape, or other portable storage devices, and removed from the laboratory.
System Backup
Ongoing procedures to ensure the security of patient data and user profiles
(usernames and passwords) to prevent unauthorized access must be in place
system security
Users should have access only to the patient information and LIS functions needed to perform their job (minimum necessary use).
system security
it should be installed to protect the system from harmful malware, especially for networks with a Windows operating system
antiviral software
facilitate the processing of clinical specimens.
barcoding
The patient number, patient demographics, time/date, and test are written in normal readable letters.
barcoding
The LIS can be connected to clinical instruments and other information systems
through an EDI.
interface
typically bidirectional, meaning information is sent to and from the instruments and the information systems
interface
analyte results from an instrument are sent to the LIS, but the LIS cannot send requests to the instrument.
unidirectional interface
it was adopter So that instruments and computers used in healthcare can communicate with each other
Health Level 7
is an international committee formed in 1987 to formulate data standards, a set of rules that allow healthcare information to be shared and processed in a uniform and consistent way.
HL7
it needs to be in place if the computer system goes down
a contingency plan for manual procedures
