Diagnostic Laboratory Operations Determine if a Patient Receives an Accurate Report on Time. Each day, a laboratory manages all of the different aspects of the process including patients, samples, staff, analyzer equipment, reagents, billing and reporting. It is very easy for a single error in any one part of the process to affect other areas. For example, a sample tube being improperly labeled will result in a delay of the report; while an expired reagent will cause the run to be halted. The purpose of this guide is to provide practical guidance for managing the daily operations of a diagnostic laboratory, with applicable methods that may be utilized by pathology laboratory owners and diagnostic center managers throughout India.
Understanding Diagnostic Lab Operations Through Every Day
The laboratory daily operations involve the entire process of opening to closing. This includes checking the status of equipment, performing quality control checks on testing systems, and reviewing inventory. Throughout the day, the laboratory staff will register patients, collect and receive patient samples, perform the testing requested, and generate reports. At closing, the staff will reconcile and transfer all unresolved sample requests, reports generated during the day, cash and billing records to the incoming shift. To help ensure that the laboratory workflow is consistent from one collection site to another, a simple daily check-list should be created for each employee's job function.
Patient Registration and Appointment Management
Registration will determine all subsequent actions. The patient's name, age, sex, telephone number, referring physician, and requested tests should be recorded, and verified by the patient. An incorrect age or sex may result in inappropriate reference range selection, while an incorrect telephone number may cause delay in receiving reports. Schedule appointments for fasting tests, home collection, and during peak hours to help reduce congestion. Integrate the registration process into your billing system so that tests ordered are matched against tests billed. Mandatory fields and drop down menus for testing options will help to minimize errors made during the registration process.
Sample Collection and Barcode Identification
Every sample collected will be identified by the person collecting the sample. When labeling a tube at the time of collection with the patient present, confirm the patient's identity (name) and provide a unique bar code/ID that corresponds with the patient's registered record. Follow all procedures regarding the type of tube, order of drawing and required volume of each test. Some common errors when collecting samples include: labeling the tube prior to collection; confusing similar names; hand-written identification numbers; and using the wrong container for the requested test. Barcoding can help prevent many of the transcription errors associated with manual entry, however, staff compliance is also necessary.
Sample Processing and Tracking
The process begins when samples are received and verified for accuracy (ID, tube, volume, condition) based on the submitted list. Samples are assigned laboratory numbers through accessioning, after which they are sorted by department and priority. Samples that need immediate attention are processed first while samples that do not require immediate attention are processed in groups. It is necessary to record every stage of sample processing (e.g., received, centrifuged, on analyzer, completed) so that anyone can locate the position of any given sample. A dispatch list reviewed upon receipt of samples at the facility allows for the identification of missing samples sent from collection centers.
Laboratory Staff and Workload Management
Laboratory staff management is primarily concerned with definition. Identify who will be responsible for registration, collection, processing, verification, and release, as well as who will cover for other employees when they are absent. Schedule your shifts based upon when you anticipate the highest level of activity (most commonly during the morning), and distribute the work load equally. To increase communication between departments, provide a short hand over note at each shift change and a daily briefing. Provide ongoing education to employees regarding SOP's, safety procedures, and new equipment to ensure consistency of practice.
Diagnostic Analyzer and Equipment Management
Before taking the first sample, verify that the reagent levels, calibration state, waste disposal status, and alarm functions of all analysis equipment are functioning properly. Maintain and calibrate equipment according to the manufacturer's recommended intervals, and document these activities with dates. Ensure that analytical instrument communication is active so that data can be transmitted accurately, and maintain a backup plan (a manual method) for collecting data. If an item of analysis equipment malfunctions, document the date/time of the malfunction, notify your team, transfer samples to another method of analysis (or a partner laboratory) if possible, and document the repair. The documentation of equipment failures can identify patterns in equipment failure.
Quality Control and Accuracy
Internal Quality Control involves testing control materials in accordance with the procedures outlined in your SOPs and taking action when results exceed established limits. External Quality Assessment compares your performance against that of other laboratories. Both types of assessment should be documented, as well as the corrective actions taken. Both of these assessments represent operational controls. Verification of test results and final approval of reports must be performed by professional staff (e.g., pathologists) who exercise professional judgment. Standards such as those from NABL may serve as reference sources for compliance with applicable regulatory requirements.
Test Reporting and Report Delivery
Results are either entered manually or transferred from analyzers, then compared to ranges and past results, prior to a qualified professional reviewing the report. The consistent formatting of the report, including clearly labeled units and reference ranges, makes it easier for both doctors and patients. Patients have the option to receive their reports in print, via email, or electronically (via a secure portal). When an error occurs on a report, document what was corrected, who corrected it, and the reason for the correction. Notify both the physician and the patient of the error. Provide the estimated turn-around-time for each type of testing at the time of patient registration. For example, if a patient has routine biochemistry testing, indicate that the results will be available within one day. Keep patients informed of any changes to the expected turn-around-time.
Billing and Inventory Management
Billing is to reflect registration and tests conducted. Payments, discounts and dues are to be updated each day. Cash and electronic payment methods are to be reconciled at the end of each day. Reagents and consumables used in testing are to be tracked as per their batch and expiration date. First-expired first-out (FEFO) principle is to be followed. Minimum stock levels are to be established based upon the volume of tests being performed and the time required for suppliers to deliver the ordered items; this will allow for ordering of additional items prior to a shortage which would prevent testing. Stock records are to be maintained in an orderly manner for auditing purposes. At the close of each business day, all tests billed during that day must have either a corresponding test result or a pending status.
Common Daily Operational Challenges in Diagnostic Labs
- Sample Identification Errors: Label At The Bedside, Use Barcodes And Re-Check ID Upon Receipt
- Keep track of the time it takes to process tests by test, and make sure that samples with immediate needs are processed separately from those that can wait.
- Staff coordination problems: assign clear roles and use a handover note.
- Equipment downtime: Plan for scheduled preventive maintenance, maintain an inventory of extra consumable parts, and develop a contingency plan.
- Manual Data Entry: Use analyzer interfacing and mandatory fields to decrease the number of times you enter data into the system.
- Inventory shortages: set minimum stock levels and review expiry weekly.
- Check for any delayed reports every afternoon, and verify the contact information of all registered users.
- Incomplete documentation: take notes of your work in real time using either simple paper-based forms or digital ones.
How to Improve Daily Laboratory Operations
Begin with establishing consistent daily workflows through a single-page checklist for each job function. Create clear job descriptions to ensure that all tasks are dependent upon written documentation rather than memory. Implement bar-code identification systems, measure the turnaround times for individual tests, and maintain current records for both equipment maintenance and quality control programs. Hold short meetings to promote better communication among staff members, and produce a daily report on laboratory operations including number of samples received, number of pending tests, delayed test reports, and stock levels. Involve senior laboratory personnel in selecting performance indicators as they are most likely aware of the areas in which delays occur. Alter only one process at a time, and evaluate the effects of the change after several weeks.
Role of Laboratory Management Software in Daily Operations
Laboratory management software will integrate your registrations, samples, tests, reports, bills, and inventories into a single cohesive unit. When applicable, the software will also incorporate any integrated analyzer capabilities from your lab equipment. As a result, there will be less duplicative data entry and you will have visibility into the status of all pending items. An example of a Lab OS powered by artificial intelligence (AI) designed specifically for diagnostic laboratories is MargLabz.
MargLabz includes over 40 individual modules that address patient/sample management, test/report management, billing, inventory, and business insight. The purpose of laboratory management software is to enhance your team's productivity and efficiency, however, it does not replace the expertise of your qualified personnel or the established Standard Operating Procedures (SOPs) within your organization. Prior to implementing a new laboratory management system, evaluate its compatibility with your existing workflow processes. If you wish to observe how MargLabz can be utilized to streamline your operations, you can schedule a free demo.
Conclusion
The successful operation of a diagnostic laboratory relies upon the following elements: structured workflow processes, trained personnel, properly functioning equipment, consistent quality assurance procedures, and appropriate use of digital technologies. Begin by focusing on a single element (e.g., sample identification, turnaround time) and expand upon it as you progress.
