The Clinical Laboratory Information System (LIS) provides facilities for clinical laboratory staff to produce comprehensive, accurate and legible test result reports.
It also helps provide timely and precise laboratory information to clinicians. With LIS, the laboratory staff can focus their efforts on providing professional services rather than doing other things like answering phone enquiries and compiling statistics.
By using the LIS analyser interface (bi-directional and uni-directional) and bar coding technology, laboratory workflow and procedures can further simplified and streamlined.
LIS can also produce adequate, reliable and rapid management information for laboratory to review various aspects of its services to the patients
Components of LIS
A good LIMS has three main components:
Rather than central mainframes, the LIS can now use “servers” on a network that interfaces with “clients” or workstations.
As more and more computers are brought into a network to work together, they are organized into logical architecture so that each computer’s role and function are clearly delineated.
It divides information processing between front-end (client) components and back-end (server) components.
Purpose of LIC
Physicians and lab technicians use laboratory information systems to coordinate varieties of inpatient and outpatient medical testing, including
Manage patient check in, order entry, specimen processing, result entry and patient demographics.
Purpose of LIC
Tracks and stores clinical details about a patient during a lab visit.
Keeps the information stored in its database for future reference.
Most adept at
Sending laboratory test orders to lab instruments
Tracking those orders
Recording the results, typically to a searchable database.
Scope of LIC
The main application of LIS in most laboratories is sample management and sharing of results with clients. However, the scope can be expanded to include:
Bar coding based identification of samples
Establishing sample custody chain within the laboratory through analyst assigned codes
Document control on issuance and validity
Scope of LIC
Inventory of stocks such as glassware, chemicals, working standards, reference materials and instrument spares. Warning messages can be generated when stocks begin to fall below a set value.
Calibration and maintenance of instruments with provision for warning messages when calibration or maintenance becomes due.
Workload management of laboratory personnel
Quality control to display warnings if non – validated methods are adopted
Limitations of LIS
Training—personnel training is required and, because of the complexity of LIMS, this training can be time-consuming and expensive.
Time to adapt to a new system—when starting up a computer system, it may seem inconvenient and unwieldy to laboratory staff. Personnel accustomed to manual systems may be challenged by such tasks as correcting errors, and uncertain of how to proceed when encountering situations where a fi eld must be filled in.
Clumsy interface – Frustrations that come with an interface that is not user-friendly or has a steep learning curve can detract from the productivity advantages that could be gained.
Limitations of LIS
Lack of customizable dashboards – While a dashboard is a time-saver, having one that doesn’t give you the information you need the most is not helpful.
Non-integrated tools – A key advantage of good lab solutions is the integration of the tools and software. Without seamless integration, your risk of error is increased and efficiency is degraded.
Users of LIC
Physicians and lab technicians use laboratory information systems to coordinate varieties of inpatient and outpatient medical testing, including hematology, chemistry, immunology and microbiology.
