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 • 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 • 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
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
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
