LABORATORY INFORMATION SYSTEM

LABORATORY INFORMATION SYSTEM (LIS)

What is laboratory information system(LIS)?

       -Is the computer software that processes stores and manages data from all stages of medical processes and testes .

        Physicians and laboratory technicians use laboratory information systems to coordinate varieties of inpatient and outpatient medical testing ,including hematology ,chemistry, immunology microbiology.

OPARATION OF  LIS

The LIS should incorporate advanced administrative and financial functionalities ,including the following:-

1.       Ability  to generate and transmit the necessary forms and notification for reimbursement of test ,with the appropriate test cord.

2.       Tracking of costs of laboratory operation ,including consumable ,labor, amortization, and other fixed costs

3.       Analysis  or pricing,  profitability, ”make-or-buy” decision tools and at reach client management capabilities  .

4.       Workload statistics based on system variable such as time logged in, number of test verified, and instrument raw test counts, as well as inputs.

5.       The system have enough capacity to record large datasets and interface with legacy system to capture historical laboratory data, with the goals of storing lifelong result on each patient.

6.       The system should capture industry standards for coding, billing, documentary generation, and interface formats such as CDC.

7.       The user interface and navigation should be intuitive and user friendly.

FEATURE OF LIS

LIS-are listed under the following sections such as:-

§  Information security

§  Test ordering

§  Specimen collection, Accessioning and processing

§  Analytic phase

§  Result entry and Validation

§  Resulting reporting

§  Notification management

§  Data mining and correctional  reports

§  Method validation

§  Quality Management

§  Administrative and financial Issue

TO PRODUCE REPORTS

The system should be able to provide a variety of reports for use in patient care, include standard and user definable reports organized by test, test group, date, date range, ordering provider or provider group, clinic or specialty and sequential or tabulated cumulative worksheets.

SAMPLE LABELING

Purpose

This policy defines labeling requirement for acceptance of samples by laboratory personnel and defined criteria for rejection of samples in the routine setting.

How to label?

1.      Specimen must be labeled for prevent any hazard in the laboratory, ensure:-

Before collecting/labeling the sample, the patient identity must be confirmed: If any discrepancy in patient identification exists, it must be resolve before collecting the sample . Confirm identity by either;

a)Inpatients ; Emergency surgery :comparing the computer generated label, or requisition to the patient wristband.

b)Out patients; having the patient state his/her name and DOB.

2.      Label the sample in the presence of the patient with complete patient.

3.      If multiple sample, label with numbers(preferable) or letters.

4.      If the source is lengthy , use number or letters with an a bloviated source on the container.

5.      Label full patient name

6.      Label data , time of sample collection.

How to capture? 

The manual label should be used for capturing patient and Laboratory information by using paper .

All information  in the laboratory captured with paper, information which needed to captured in a paper are:-

·         Patient information

·         Equipments ant Instruments information

·         Test result s

·         Management information

               Also some information captured to the electronic device such as computer.

Ø  The computer should identify all specimen which received in the laboratory without an order or accession , but with appropriate patient identifiers.

Ø  The system as ability to present the collector with list of pending laboratory orders and generate  unique bar-corded labels to the bedside upon scanning the patient identification wristband or other unique physical patient identifiers.

Ø    The system should have the ability to de-identify  and codify specimens for search purpose , and include database management capabilities for bio banks and tissue repositories.

How to save result?

             The LIS should not only serve as a repository of laboratory result generated by the analytic process , but also guide the analytics into providing high-quality results that are accurate , reproducible , and appropriate to the clinical situation.

           Before save result ensure that all information should be well to help quality performance in the laboratory.

Conclusion 

Laboratory information system can improve laboratory operations   and improve patient care.
