IQCP for the Akers Bio PIFA Heparin Platelet Factor 4 Rapid Assay

Transcription

1 On December 31, 2015 the ability to use Equivalent Quality Control (EQC) policies will expire. Laboratories will be required to either follow the quality control regulations as outlined in CLIA 88 or develop an Individualized Quality Control Plan (IQCP) to replace the current EQC option. This plan is the new alternative CLIA quality control (QC) option that will provide for equivalent quality testing to meet the CLIA regulations for nonwaived tests. The IQCP process includes a Risk Assessment (RA), Quality Control Plan (QCP), and Quality Assessment (QA). An IQCP must address the potential failures and errors identified in the entire testing process: preanalytic, analytic and postanalytic phases of testing 1. Using the Centers for Medicare & Medicaid Services (CMS) and CDC publication, Developing an IQCP, a Step by Step Guide, Akers Bio has developed the following tools to make your transition to IQCP easier. The workbook is located on both the CLIA and CDC websites 2. It provides explanations and templates to guide each lab through the requirements of an IQCP. Please bear in mind that while Akers Bio has provided a useful template, CMS expects your IQCP to reflect your laboratory conditions and not what Akers Bio might assume about your laboratory operation or conditions. Review the supplied template thoroughly and customize to your individual laboratory. Your laboratory director is responsible for deciding whether the laboratory will utilize IQCP for the Akers Bio PIFA Heparin/PF4 Rapid Assay and for ensuring that the quality control plan (QCP) developed effectively meets the IQCP requirements. The Akers Bio PIFA Heparin/PF4 Rapid Assay is a FDA cleared device, categorized moderately complex under CLIA. This test is a candidate for an IQCP because Akers Bio s Instructions For Use recommend performing external QC less frequently than required by CLIA. If you are a current user of this product, much of the information needed to perform the risk assessment (RA) for the PIFA Heparin/PF4 Assay has likely been accumulated in the process of routine operations in the laboratory. For example, verification of manufacturer s performance specifications, QC performance, personnel training and a device lot log can all be used to support your RA. 1 "CLIA Brochures - Centers for Medicare & Medicaid Services."

2 On the following page Akers Bio has provided a general template relating to common specimen risks associated with the Akers Bio PIFA Heparin/PF4 Rapid Assay. Some risks are inherent to laboratory testing in general, and procedures should exist to handle these risks. Akers Bio has not included these risks or actions taken by your laboratory to control them. As a manufacturer, Akers Bio may offer suggestions and provide input to your laboratory concerning the specifics of your IQCP, but your laboratory must develop and perform its own IQCP. ASSESSING THE SPECIMEN RISKS Questions to Consider Relating to Specimen 1. Are written procedures available and followed for managing unacceptable specimens? In your laboratory, is there a general procedure for specimen rejection which is established and followed? Add the following PIFA requirements to your laboratory s existing protocols related to the above: Anticoagulated samples are not suitable for test with this assay and must not be used. Frozen, thawed, hemolyzed, icteric, lipemic (of an excessive nature), bacterial contaminated specimens, or controls from other test kits should not be used, and can produce erroneous results. Risk can be reduced to acceptable levels by TRAINING. Use the supplied Quiz to document training. 2. Does your laboratory have a procedure to handle specimens which are improperly labeled? If yes, reference in your Risk Assessment Findings. This procedure will be reviewed in your Quality Assessment. Page 2 of 17

3 Risk Assessment Components What are our possible sources of error? What can go wrong? Gather information, from the manufacturer s instructions and other resources, on how we should be performing the testing process. Specimen Collection Can our identified sources of error be reduced? /No Not Applicable (N/A) How can we reduce the identified sources of error? Indicate how to reduce possible error sources. Internal controls Actions taken by laboratory Safeguards in the test system or laboratory practices SPECIMEN Manufacturer s instructions FRESH Serum must be used with the PIFA Heparin/PF4 Rapid Assay. Do not use frozen and/or thawed specimens. Train testing personnel to verify use of proper specimen collection tubes. Use Quiz supplied by Manufacturer. Whole Blood specimens must be collected in Red Top Tubes ONLY. Plain, Glass Red Top tubes OR Plastic, Red Top Tubes, with Clot Activator must be used to obtain patient specimens; no other collection tubes are recommended for use, including gel serum separation tubes (SST). Train testing personnel not to use frozen and/or thawed specimens or SST tubes. Use Quiz supplied by Manufacturer. Page 3 of 17

4 Specimen Preparation: Manufacturer s instructions SPECIMEN In accordance with CLSI Guideline H18-A3, Procedures for the Handling and Processing of Blood Specimens, serum should be separated from contact with cells within a maximum of 2 hours of the draw. Clot Activation: Patient specimens must be allowed to clot before centrifugation. Consult Collection Tube Manufacturer s instructions for mixing protocols and recommended clotting times (clotting times range from thirty (30) to sixty (60) minutes). Centrifugation: The specimen should be centrifuged at the end of the clotting period in strict accordance with the Collection Tube Manufacturer s instructions for speed and duration of centrifugation. IMPORTANT: Patient specimen should not stand on the clot for longer than 60 minutes after centrifugation or the PIFA test result may be invalid. Train phlebotomy team, central specimen processing personnel to insure protocols of collection tubes are appropriately followed (this is not specific to the PIFA test and should be already controlled). Train testing personnel to remove specimen from clot within 60 minutes after centrifugation. Verify training using Quiz supplied by Manufacturer. Testing time frame/stability of specimen: Manufacturer s instructions Specimen Storage Properly prepared serum that has been removed from the clot, but cannot be tested immediately, should be stored refrigerated (2-8 C; F) for no longer than 72 hours. Train processing or testing personnel (as applicable) to verify and document: Collection time and time of receipt in laboratory Proper storage and processing of specimen Note: Any refrigerated serum should reach an ambient temperature prior to performing the test. Verify training using Quiz supplied by Manufacturer. Page 4 of 17

ASSESSING REAGENT RISKS Questions to Consider Relating to the Reagent 1. Is the integrity of reagents checked when received? 2. What would happen if reagents are shipped to the laboratory at a time when staff are not available to ensure proper storage (e.g. a weekend or holiday)? What would happen if there was a delay in receipt of reagents from Receiving Department? Your laboratory should have procedures in place addressing questions #1 and #2 above. Please reference in your Risk Assessment Findings. This procedure will be reviewed in your Quality Assessment. If you do not have such procedures in place, add Incoming receipt, check of reagent integrity to reagent risk assessment that follows. This risk would be reduced by training personnel and verifying effectiveness of training using the supplied Manufacturer Quiz. 3. Are all reagents removed from storage and disposed of when they have reached their expiration date? There should be a general laboratory procedure in place that deals with this scenario. Please reference in your Risk Assessment Findings. This procedure will be reviewed in your Quality Assessment. If you not such procedures in place, the possibility of use of expired reagent has already been covered in the reagent risk assessment that follows. This risk would be reduced by training personnel and verifying effectiveness of training using the supplied Manufacturer Quiz. 4. Are lot numbers recorded in a log (when new lots are received and when beginning use of different lot numbers)? 5. Is there a procedure for evaluating new lot numbers before beginning use for patient testing? The following Reagent Risk Assessment implies that tracking of lot control exists in the laboratory. It is required for the recommended QC to be effectively implemented. If there is no procedure/log in place, create a lot log for use specifically with the PIFA Assay. Page 7 of 17

15 Quality Assessment Monitoring and Review for the Akers Bio PIFA Heparin Platelet Factor 4 Rapid Assay Quality Assessment (QA) is used to determine if the quality activities you have put in place are working according to your Quality Control Plan. Each laboratory must establish a review system for the ongoing monitoring of the effectiveness of their QCP. The CMS and CDC publication, Developing an IQCP, a Step by Step Guide has a very helpful appendix (Appendix E) at the back on the workbook listing QA activities which can help you reduce the occurrence or enhance the detection of potential failures and errors 3. Based on the risks identified on the previous pages and the Quality Control Plan developed to address those risks, the following Quality Assessment Plan has been developed. You may need to add or delete portions of the plan based on the requirements of your laboratory. This plan covers general elements that you are likely already tracking. While you state the frequency and acceptance criteria in this IQCP, the monitoring activity is used for many purposes and does not need to be recorded specifically for this IQCP. Records of the review should exist in your current systems and can be used for multiple reasons. You may find it easier to use a checklist to track Quality Assessment activities. The template below has been suggested in the Developing an IQCP, a Step by Step Guide 4. Alternately, you can use a combination of a checklist in a tabular form and detailed explanation of the QA activity which is being monitored. As your lab is performing many Quality Assessment activities, you should choose the format which most closely matches your needs.
