The advice and guidance CLIAC provides to HHS pertains to general issues related to improvement in clinical laboratory quality and laboratory medicine practice. The frequency of errors can be determined by reviewing historical data; however, the accurate determination of patient m50–a resulting from these errors is highly variable and a nearly impossible task.

Stakeholders expressed concerns at this meeting that manufacturers did not provide laboratories with csi information regarding QC and that a one-size-fits-all requirement for QC would not work with all new technologies. If the document is revised or amended, you will be notified by email. Support Center Support Center. The most recent survey, inevaluated overlots of over 32 million pieces of media.

Subsequently, CAP conducted three surveys among clinical microbiology laboratories, and to determine the failure rates of commercially prepared media. Again, following the CLSI statistically based standard for antimicrobial susceptibility QC testing should be sufficient, and it is unclear how the development of an IQCP will improve the quality of reporting patients’ results. Errors in laboratory medicine can certainly have significant effects on patient clxi, and we in the clinical microbiology community clearly support quality improvement measures which have the potential to positively impact patient outcomes.

Likewise, for commercial microbial identification systems MIS that use two or more substrates, CLIA ’88 requires QC testing with positive and negative reactivity controls for each substrate with each batch, lot number, and shipment of reagents.

September 25, Content source: However, there were concerns expressed by some in industry and in laboratories, as well as by other experts, about the rigidity and the limit of scope with EQC.

Individualized Quality Control Plan (IQCP): Is It Value-Added for Clinical Microbiology?

csi Author information Copyright and License information Disclaimer. You may delete a document from your Alert Profile at any time. Nearly laboratories provided data for nearly 10, lots of MIS. These data demonstrated that retesting of many types of commercially prepared microbiological culture media with QC strains in-house will not improve the quality of patient results.


Clinical Laboratory Improvement Advisory Committee (CLIAC)

MA includes guidelines that may be followed when using an MIS of proven reliability to take a modified QC approach, rather than meeting requirements included in the Clinical Laboratory Improvement Amendments of regulations. College of American Pathologists. Prior to that time, there were few xlsi for laboratories.

The letter requested data from CMS to support the notion that applying IQCP to clinical microbiology tests would improve patient outcomes. Your Alert Profile lists the documents that will be monitored. Generally, CLIA ’67 affected large hospital and independent laboratories, while physician office laboratories and small laboratories were essentially left unregulated.

Again, as stated in the ASM letter to CMS, there are many tests in clinical microbiology where additional QC testing does nothing to prevent reporting erroneous results on patient’s isolates or samples. Millerb and Janet Hindler c. Spring Meeting Summary Report Cdc-pdf.

Several decades ago, it was recognized that testing of QC strains by the user for commercially prepared media demonstrated few QC failures and imposed a substantial financial burden on microbiology laboratories. It specifies responsibilities of the manufacturer, distributor, and user. Notes The views expressed in this Commentary do not necessarily reflect the views of the journal or of ASM.

These data showed that the failure rate due to the MIS itself cclsi less than clsu. NovemberVenue: Developing an IQCP involves a review of the entire testing process, beginning with specimen collection preanalytic and continuing through the analysis of the specimen analytic until the final test result is reported postanalytic. Quality control for commercial microbial identification systems. US Statutes at Large 81 Clinical and Laboratory Standards Institute. It should m50- noted that these guidelines, along with the tenets of EQC, can still be used by clinical microbiology laboratories as a component of an IQCP.

CLSI MA – Quality Control for Commercial Microbial Identification Systems; Approved Guideline

For laboratories accredited by the College of American Pathologists CAPit should be noted that the most recent version of the CAP checklist will require testing of an external control every 31 days 5. Due to the m50a- and advancement of MIS, this requirement has become difficult and costly for clinical microbiology laboratories and has not been shown to prevent errors when testing patients’ isolates.


J Clin Microbiol Journal List J Clin Microbiol v. To receive email updates about this page, enter your email address: There are three components to an IQCP: This standard is also available to be included in Standards Subscriptions.

The views expressed in this Commentary do not necessarily reflect the views of the journal or of ASM. Performance standards for antimicrobial susceptibility testing; 25th informational supplement. M50a- also understand that there are common errors in microbiology that need to be managed; however, it is m50-w to see how the implementation of IQCP and the elimination of both EQC and the use of recommendations in CLSI standards and guidelines will have a positive effect for our patients.

J50-a at Clzi 81 To this end, our clinical microbiology community is more than willing to have its members assist CMS in this endeavor. The QC recommendations in the CLSI standards are supported by data demonstrating that following CLIA default QC daily testing of QC strains will not improve the quality of patient results for laboratories that have documented satisfactory performance with a specified amount of daily QC testing.

CLIA ’67 required these large laboratories to adhere to quality control QCproficiency testing PTtest performance, and clei standards. IQCP will soon be the law of the land for clinical microbiology laboratories; time will tell if it improves our ability to decrease cli patient outcomes. On 2 SeptemberASM’s Committee on Laboratory Practices wrote a letter to Andrew Slavitt, Acting Administrator for CMS, stating m50-w we as clinical scientists rely on published literature, statistically derived data, and evidence-based medicine to guide our practice http: Similarly, testing commercially prepared exempt media with QC strains will not prevent a technologist from choosing a poor quality portion of a sputum sample for plating onto a blood agar plate.

CLSI document EP23 also describes good laboratory practice for developing and maintaining a quality control program for medical laboratory testing using recognized risk management principles.
