Transcript Laboratory Information Systems

Laboratory Information System
Dr. Milind Bhide (M.D.)
LIS – How important is it ?
 As important as a microscope.
 If the LIS fails, Lab work stops
 Information technology and logistics key
components differentiating small and
corporate labs.
 Information and Communication skills are a
must for today’s world.
LIS - Key Components
 FRONT END


Part of the software visible to the user
eg. Visual Basic, JAVA, Web front end
 BACK END


Part of the software not visible to the user
eg. Access, Sql server, Oracle, DB2
LIS FEATURES

Patient registration and report printing
Barcode printing
Instrument interfacing
Inventory management
Training
Interconnecting central lab with centers
SMS and email of reports
Patient Information Module
 Unique Sample Id
 Association of Patient Id with Sample Id
 Information to be recorded



Age- related normal ranges
Relevant patient history
Patient preparation - Fasting etc.
Patient Contact Information - to convey critical
values
Barcode
 Numeric or Characters coded as lines
 Different formats


Code 39
Code 128
 Sample ID coded as Barcode
 Barcode read by readers on instruments

INVENTORY MANAGEMENT
Inventory management




Record as the supplies come
Record reagents used as testing is done
The difference is inventory
Check it against average usage and order if
necessary
INVENTORY MANAGEMENT
 Use 2D barcode provided by the
manufacturer.
 Scan reagents as they arrive
 LIS tells about lot and bottle use
 Define re-order level
 Reagent lot and bottle (Date and time of
first use)
Quality management
 We are expected to run 2 levels control for
common tests
 30 X 2 ie. 60 values obtained
 Print , feed the values
 Plot charts
 If the day starts at 9:30 when to take
corrective action and when does the work
begin ?

How to connect to a central lab ?
 Central Lab location.

Located at a place where internet facilities are
available.
 Internet facility




Telephone broadband
Wifi
3G
Leased lines
Internet Connections
Internet connections
 Shared connections

MTNL Broadband
Tata photon / Reliance
Mobile 3 G
Bandwidth is not dedicated.
Speed depends on the number of users at that
time.
Internet connections
 Leased lines



Dedicated line with guaranteed download and
upload speed.
Highly reliable
Guaranteed uptime
 More expensive
Creating PDF of reports
Backup Policy
 Well defined with a back policy in place
 Best to keep multiple backup sets.
 Best to store important data on a central
server.
 Managed servers are available.
 Linus based NAS (Network attached
storage) affordable
NAS (Network attached Storage)
Remote Desktop Protocol (RDP)
Remote Desktop Protocol
Sending SMS
Association of Practising Pathologist
of India (APPI)
 To increase the member by active membership drive
 To conduct continual medical education to advance the
knowledge and imbibe the good practices
 To represent the interests of the practising pathologists
 To start medico-legal cell to support pathologists
 To create awareness amongst medical practitioners and
general public with regards the quackery in diagnostic
practices
 To facilitate and improve quality and effectiveness in
laboratory
