- 2. OBJECTIVES DISCUSS The functions of LIS EXPLAIN The functions of LIS ELABORATE Flow of information in the laboratory ENJOY The ride
- 3. A medical laboratory is one of the rare places you go wishing to find nothing -someone famous
- 4. involved in storing, recording, recovering and consolidating laboratory information from the clinical and anatomic sections of the laboratory Laboratory Information System (LIS)
- 5. CLASSIFICATION BY FUNCTION: CLINICAL PATHOLOGY CLINICAL CHEMISTRY HEMATOLOGY IMMUNOHEMATOLOGY MICROBIOLOGY IMMUNOLOGY CLINICAL MICROSCOPY ENDOCRINOLOGY MOLECULAR BIOLOGY CYTOGENETICS TOXICOLOGY THERAPEUTIC DRUG MONITORING
- 6. ●SURGICAL PATHOLOGY ●IMMUNOHISTOPATHOLOGY ●CYTOLOGY ●AUTOPSY ●FORENSIC PATHOLOGY ● MOLECULAR PATHOLOGY CLASSIFICATION BY FUNCTION: ANATOMIC PATHOLOGY
- 7. 1) conform to standard classifications and validity of data set by the DOH 2) ensure the integrity and internal consistency 3) maintain patient confidentiality and security of the information 4) Allow easy access by the laboratory managers up to the health professionals 5) and allows various data to be integrated to the laboratory data GOAL OF LIS
- 8. PURPOSE OF LIS IMPROVE the quality of data because it plays a central role on laboratory decision making OPTIMIZE efficiency in laboratory operations for health care delivery CONNECTS with patient registration, billing systems and EHR PROVIDE accurate and timely results ASSIST in the decision-making of health professionals for the promotion, diagnosis, treatment and management of health
- 10. COMMON ERRORS IN THE LABORATORY WORKFLOW PRE-ANALYSIS -obtaining inadequate or insufficient samples -samples taken from the wrong patients -specimen placed in the wrong chemical/container or tube -ordering wrong tests -identification problems related to the patient and the source of the specimen -lack of clinical information when required ANALYSIS -Bad reagent lot -Instrumentation failures -Wrong data entry -Erroneous transcript POST-ANALYSIS -Delay of the delivery of the results -Failure to report or reporting to the wrong health care provider -Transcription errors -Incorrect results -Misunderstanding of the results by the clinician, -Failure of clinician to see the report.
- 11. Pre-analysis Patient registration Test ordering Customized requisitions (e.g., outreach clients) Phlebotomy draw lists Bar-coded collection labels and aliquot labels Specimen tracking/racking system Instrument worklist (via interface and automatic download) Manual worklist Manual results entry Automated results entry via interface Results validation and manual or automatic release Quality control Analysis LIS Functions Outpatient: Patient record (name, sex, age, address) input in LIS Inpatient: Collect the data from hospital registration system Physicians fill up a requisition form through the HIS and electronically sent to LIS Print out the patient list for phlebotomy and appropriate barcode label for each order. Update the LIS if the specimen was already received in the laboratory. Mark as “collected” to “received” Samples are loaded to the instrument and barcodes are scanned. LIS will electronically send the test order to the analyzer list of patient may be printed out with the designated test order Analyzer sends the results to the LIS Medical technologist will assess the validity of results and identity whether there need for rerun or referral Result of regular quality control checks are recorded on the quality control files
- 12. Post-analysis Requisition-based patient reports Cumulative patient reports Corrected report Results inquiry Electronic reporting to external interfaced systems (e.g., HIS, billing) Pending (incomplete) list Pending (incomplete) list Turnaround time reports Workload statistics Ad hoc report writer HIS and instrument integrity monitoring tools Management LIS Functions Reviewing of results: flagged results such as critical values Printing and or reporting of results to the physician which is available for viewing on the HIS LIS sends the charges or test performed to the HIS Ad hoc reporters allow the the MT to generate results and reports without the use of programming languages defined as the time from receipt of the specimen in the laboratory to the time the results are verified in the computer or called to a physician or nurse used to compare work load and capacity at specific dates and times
