Key Processes in Laboratory Information Systems: Managing Workflow for Accurate Diagnostic Results

Summary

• Once an order is saved in an LIS system, it undergoes several key processes before reaching the final stage of completion.
• The LIS system helps manage the Workflow efficiently, ensuring accurate and timely results for patients.
• From specimen processing to result reporting, each step in the LIS system plays a crucial role in the overall diagnostic process.

Introduction

Laboratory Information Systems (LIS) play a vital role in the healthcare industry, especially in medical diagnostics. Once an order is saved in an LIS system, a series of events are set in motion to ensure the smooth and accurate processing of the sample and generation of results. In this article, we will explore what happens after an order is saved in an LIS system, detailing the various stages and processes involved in the diagnostic Workflow.

Specimen Collection and Processing

After an order is saved in an LIS system, the first step in the process is specimen collection. This involves obtaining the sample from the patient, which could be blood, urine, tissue, or any other bodily fluid. Once the specimen is collected, it is labelled with the patient's information and sent to the laboratory for processing.

Upon reaching the laboratory, the specimen undergoes processing, which may involve centrifugation, staining, or other preparatory steps depending on the type of test being conducted. The information about the specimen, including its type, volume, and any special handling requirements, is recorded in the LIS system to ensure traceability and accuracy throughout the testing process.

Analysis and Interpretation

Once the specimen is processed, it is ready for analysis. The laboratory equipment used for testing is interfaced with the LIS system, allowing for seamless transmission of data and results. The Test Results are generated by the instruments and captured in the LIS system, along with any relevant interpretive comments or notes from the laboratory personnel.

At this stage, the laboratory staff reviews the results to ensure accuracy and completeness. Any Discrepancies or abnormal findings are flagged for further investigation, and the necessary follow-up actions are initiated. The LIS system plays a crucial role in facilitating this review process, providing easy access to patient data and historical results for comparison.

Result Reporting

Once the analysis and interpretation are complete, the final step in the process is result reporting. The Test Results are verified by the laboratory staff and released through the LIS system. The results are documented in the patient's electronic health record (EHR) and made available to the requesting physician or healthcare provider for review.

The LIS system ensures timely and accurate result reporting, reducing the risk of errors or delays in the diagnostic process. Any critical or abnormal findings are immediately flagged for attention, allowing for prompt clinical intervention if necessary. The result reporting stage marks the completion of the diagnostic Workflow, providing essential information for patient care and treatment decisions.

Quality Control and Assurance

Throughout the entire process, from specimen collection to result reporting, Quality Control and assurance measures are in place to ensure the reliability and accuracy of the testing performed. The LIS system helps monitor and track quality metrics, such as turnaround times, Specimen Integrity, and instrument performance, providing valuable data for continuous improvement and compliance with regulatory standards.

Regular audits and reviews are conducted to assess the effectiveness of the laboratory processes and identify areas for enhancement. The LIS system serves as a central repository for Quality Control data, allowing for real-time monitoring and analysis of key performance indicators. By maintaining high standards of Quality Control and assurance, laboratories can deliver reliable and consistent results to support patient care and clinical decision-making.

Conclusion

After an order is saved in an LIS system, a complex series of processes and procedures are set in motion to ensure the accurate and timely processing of samples and generation of results. From specimen collection to result reporting, each step in the diagnostic Workflow plays a crucial role in delivering high-quality laboratory services and supporting patient care. The LIS system serves as a critical tool in managing the Workflow efficiently, maintaining data integrity, and facilitating communication among laboratory personnel and Healthcare Providers. By understanding the intricacies of what happens after an order is saved in an LIS system, we gain insight into the essential role of laboratory informatics in modern healthcare delivery.
