Executive Vice President's Message

The CLSI Leadership Conference & Workshop

Melding the hottest issues of the day—Equivalent (Alternative) Quality Control, Patient Safety, and Risk Management—our annual leadership conference features a full-day hands-on workshop, Risk Management Tools for Improved Patient Safety. Presented by experts in their fields, this event voices the most current perspectives from industry, government, and healthcare professionals on these prevalent topics. This workshop is aimed at clinicians, laboratorians, manufacturers, and government representatives interested in implementing a process to identify the hazards associated with their areas of specialty, to estimate and evaluate the resulting risks, to control these risks, and to monitor the effectiveness of that control in their home institutions. The workshop is on 28 April and offers attendees continuing education credit.
 
A dynamic, interactive program, the CLSI 2006 Leadership Conference (26 to 28 April) combines consensus standards development meetings with in-depth training sessions.  The general session addresses risk management in emergency situations, from both legal and international perspectives.  In addition, both the president’s reception on the evening of the 26th and a general reception on the 27th from 7:00 to 9:00 pm will give attendees ample time to network, meet new colleagues, and renew old friendships.  The conference is conveniently located at Tysons Corner (15 minutes from the Dulles Airport) in Vienna, Virginia.

Take the time to meet with and learn from your colleagues and peers from around the world, keep up with the latest trends in laboratory and patient testing, and get continuing education credit to meet your professional needs.

Dr. Louis J. Dunka - A Tribute and Remembrance

Louis J. Dunka, PhD, a well-respected clinical chemist and in vitro diagnostic clinical scientist, will be missed greatly. Lou passed away leaving behind his daughter Ashley. He was 64 years old. Lou received his BS degree in Analytical Chemistry from St. Joseph’s University, Philadelphia, PA, and then his PhD in Biochemistry from the University of Alabama (UAB), Birmingham, AL, where he developed “An Automated Method for the Determination of Triacylglycerols (Triglycerides) in Serum” for his dissertation. Lou’s career took him into the IVD industry in product development, quality and regulatory, industry relations to clients, professional societies, regulatory and governmental agencies, and industry advocacy groups like HIMA and ADVAMED. I personally have had the benefit of knowing Lou for almost 30 years in each of his roles, first at American Hospital Supply’s Scientific Products (Dade Division), Fisher Diagnostics, Syva, IL, and finally at LifeScan. Lou served in many capacities in each of these companies. One consistent theme, however, in his career was participation in CLSI subcommittees, area committees, and on panels/working groups associated with liaison organizations such as ADVAMED, AACC Industrial Liaison Committee, AACC divisions (Industrial Division LIS, and CPOCT), ISO, IHE, IEEE, and HL7.

While fulfilling his corporate responsibilities with great enthusiasm, professionalism, and intensity, he was always available to help with a standards project, organize an AACC divisional meeting, or review an article or a document with the same attributes. He was someone you respected for his common sense, his network, and knowledge of the field. Lou was someone you could count on to get the job done on time, on budget, and to everyone’s expectations. His latest work as Chairholder of the Area Committee for Point-of-Care Testing was to forge new ground with a working group composed of industry, government, and providers, that was expanded to include researchers and clinicians involved in the field of continuous glucose monitoring. The purpose of the group is to establish common terminology and understanding of continuous glucose sensing with the goal of establishing a standard for glucose monitoring. His role in this group and CLSI will be greatly missed.

I’m thankful for Lou’s friendship and for all the activities we shared over the years, both professional and social.

Respectfully submitted by his friend and colleague,

Jeffrey A. DuBois, PhD

 


Positioning for Successful Quality Management System Implementation

The implementation of a strong quality management system (QMS) provides a platform for continuous improvement in service delivery:  enhancing customer service, meeting regulatory and accreditation assessments, and creating a culture of total service excellence.  The best contribution an organization can make to improve quality is to understand, document, and follow policies, processes, and procedures in their full complexity.  To establish a complete QMS, an organization needs to define the infrastructure known as the quality system essentials (QSEs) necessary to provide quality care to patients. The QSEs are the foundational building blocks that support the organization’s work operations, also called path of workflow.

Every service has a defined path of workflow, which represents the sequence of activities from the initiation of a request for a service through the provision of those services, and any necessary follow-up. In the clinical laboratory, the path of workflow begins with an order for a laboratory examination (test) and proceeds to provision of the report, and any necessary follow-up consultation. Each healthcare organization can use the same quality system essentials to manage its respective path of workflow, thus developing one universal set of policies, processes, and procedures for the quality system essentials that apply to all the services in the entire organization.

Essential Quality Management System Resources 

CLSI has recently released new editions of widely accepted “gold standards” of authoritative documents and products within its quality collection.  These documents, developed by recognized experts, provide guidance to ensure that clinical and healthcare organizations are functioning optimally to meet customer, regulatory, and accreditation requirements, and provide the highest level of patient care.

CLSI Quality System Toolkit (HS1-A2-C)
Based on CLSI document, A Quality Management System Model for Health Care; Approved Guideline—Second Edition (HS1-A2), this electronic product, which includes a PDF copy of the HS1-A2 document, provides information for designing, implementing, and maintaining an effective quality management system. The Quality System Toolkit lays the foundation for developing quality policies based on the 12 “QSEs,” controlling quality processes, and reporting and tracking occurrences.

In addition to the new toolkit, CLSI also offers a special discounted bundled collection of documents to meet targeted needs in its Quality Series (SC24-L) with the key documents for quality management activities.

Compliance Resources for Improving Quality

Technical aspects of a healthcare organization’s path of workflow are published in country-specific accreditation requirements. While each country will have its own requirements, they all have in common the need to define, document, and train for the organization’s activities. Laboratories and healthcare organizations that build accreditation requirements into their routine daily practice will always be well prepared for inspections and assessments.

CLSI provides an expansive collection of products to support implementation of a complete quality management system. Through its recognized consensus process, CLSI delivers the essential resources that organizations need to improve the quality of patient testing and healthcare services and to meet regulatory and accreditation requirements. CLSI serves as a resource to fill a gap where regulatory requirements are not currently in place, and provide practical recommendations and practices to meet regulatory requirements.

Upcoming Procedure Manual Document and Toolkit Support a Quality Management System and Compliance Needs

CLSI will soon release new editions of its procedure manual standard and toolkit:

The newly revised Laboratory Documents: Development and Control; Approved Guideline—Fifth Edition (GP2-A5), scheduled for publication in late March 2006, has been updated to include: examples of the use of process flowcharts to depict linkages between laboratory procedures; elements for writing process and procedure documents for preexamination, examination, and postexamination activities; information about writing procedure documents for multitest automated analyzers and for laboratory information systems; and the eight elements of document control.

CLSI Procedure Manual Toolkit (GP2-A5-C)
This toolkit, scheduled for spring distribution, presents the major concepts of document development and control. Included in the toolkit are nine templates that provide the framework for developing procedures and communicating and organizing information. It also includes a PDF of the revised, approved-level document GP2-A5.

At a special discount, CLSI also offers GP2-A5 as part of the bundled collection of documents, Regulatory Compliance (SC31-L), which includes documents that will help laboratories comply with regulatory requirements.

Partners to Promote Excellence in Performance

CLSI consistently maintains open communication with regulatory and accreditation organizations and it partners with them for the mutual goal of providing the tools needed to improve the quality of patient care. In November 2005, CLSI and COLA announced a partnership directly linking best practice standards, guidelines, and educational services to regulatory compliance and laboratory accreditation. Similarly, numerous CLSI documents are referenced in the College of American Pathologists (CAP) Laboratory Accreditation Program Inspection Checklists and serve as key resources for helping laboratories to satisfy accreditation requirements. During CAP’s on-going process of updating accreditation checklists, the associated reference lists will be updated with the most recently published editions of CLSI’s standards and guidelines.

Global Initiatives Provide a Complete Approach to Quality Programs

CLSI has developed the “how to” tools for implementation of quality requirements prescribed by the International Organization for Standardization (ISO). ISO 9001 defines a process model for quality that any business should use to manage its operations, ISO 17025 specifies the general requirements for the competence to carry out tests and/or calibrations, including sampling, and ISO 15189 defines standards for quality management in the medical laboratory environment.

The primary objective of ISO 15189 is to create the foundation for quality in medical laboratory services. CLSI quality guidelines provide practical approaches to facilitate organizational execution of the requirements prescribed in ISO standards and aid in the successful implementation of a quality management system. CLSI’s series of quality management system guidelines complement the efforts of ISO 15189 to provide a comprehensive quality management system approach for medical laboratories worldwide.

ISO 15189 does not substitute for US government regulatory requirements such as the CLIA ’88 legislation; however, alignment with ISO 15189 by various US accreditation agencies, such as COLA and CAP, and the establishment of ISO 15189 as the primary national standard for laboratories in many other countries around the world, strengthens the importance of this international standard. ISO 15189 is increasingly becoming the overriding, uniform global approach for quality and competence to which clinical laboratories and healthcare services aspire.

CLSI Commitment to Quality

With the rapid evolution of techniques, tests, methods, and technologies in the healthcare industry, CLSI continues to respond with the essential resources and vital guidance to improve quality management, assure patient safety, and achieve success. Through the development of new quality documents and products, ongoing efforts to forge partnerships with government and accreditation bodies, and harmonization with key ISO standards, CLSI equips organizations worldwide with the tools to provide consistent, compliant practices and efficient use of resources. Undoubtedly, CLSI embraces its commitment to advance quality in healthcare testing now and in the future.


The involvement and expertise of professionals with frontline experience is the key to the CLSI’s unique, effective consensus process. Comments and questions about CLSI documents are welcome; this essential feedback serves as the basis for updated document editions. All comments and responses are formally addressed and published in the next edition of the document.

Quality Qorner: Low Carb Documents

Lucia M. Berte, MA,MT(ASCP)SBB,DLM; CQA(ASQ)CQMgr

My local newspaper ran a column after the holiday season by a woman who had been a former mayor and state representative and has been actively involved in the community for a long time. She included a poem by an anonymous author entitled, “’Twas the month after Christmas” that began like this:

“`Twas the month after Christmas and all through the house
Nothing would fit me, not even a blouse.
The cookies I’d nibbled, the eggnog I’d taste,
All the holiday parties had gone to my waist….”

The poem continued in its traditional style and it was as if I had written it about my tasty holiday experience! It ended with the line, “Happy New Year to all and to all a good diet!”

I’ve been trying hard to make low carb living part of my lifestyle. It’s definitely a struggle at holiday time, but for the rest of the year it’s doable…and desirable. A low carb diet pares us down to eating essential, healthful foods that are good for us and keep our bodies healthy.

As a long-time inspector, assessor, consultant, and reader of laboratory documents, it’s apparent to me that laboratory documents need to go on a “low carb diet.” Just as unused carbs turn into fat that’s unhealthy for our bodies, unused laboratory documents turn into fat procedures manuals that are unhealthy for laboratory staff.

It’s not healthy to have:

  • procedures that are so lengthy as to be incomprehensible;
  • procedures that are missing essential “how to do it” steps but
    instead include unnecessary information;
  • documents that provide details about individual analytes but
    don’t describe how to do the work;
  • procedures that describe actions that others take but not the
    information the reader needs to know right then;
  • procedural revisions sitting in a big in-pile in the supervisor’s
    office because it’s so much work to rewrite them; and
  • procedures manuals that are only trotted out when the
    inspectors come.

I could list many more problems with the way laboratory procedures manuals have been historically written and organized, but I’m sure you know well what I mean. So the challenge is how to put our laboratory documents on a low carb diet, trim the fat down to lean muscle, and make them healthy.

Food is made up of proteins, carbohydrates, and fats, each with an important role in maintaining the human body. However, there can be too much of a good thing; extra pounds result from accumulation of unused carbohydrates and fat. Using this analogy, we could say that the “meat” of a laboratory document—that is, the information needed to fulfill the document’s purpose—is the protein and that untimely, surplus or out-of-place information is the carbs and fats that need elimination to make the document function more effectively. Continuing with the analogy, if a vital amine (aka, “vitamin”) is missing from the food in our diet we can suffer dire consequences. Likewise with laboratory documents; when vital information is missing from procedural instructions, errors and omissions occur that can compromise patient safety.

Probably everyone reading this has purchased a diet book at some time or another—I’ve found the “South Beach” ones to be particularly useful. Fortunately, there is a new diet book for laboratory documents that has reorganized protein, carbs, and fat into palatable document “recipes.” Just as recipes can be organized into categories such as appetizers, entrees, and desserts, laboratory documents can be categorized into policies, processes, and procedures.

The first edition of NCCLS guideline GP2 was released more than 25 years ago with a “recipe” for the contents of a laboratory procedure that was based on individual analytes. However, not all laboratory procedures are analytic. For example, neither the entire preanalytic portion of the laboratory’s path of workflow nor the related laboratory computer system procedures are about testing. Therefore, the original recipe did not fit all types of laboratory documents and the added carbs and fats have made the documents extremely unwieldy. Therefore, in 2002, the NCCLS (now the Clinical and Laboratory Standards Institute, CLSI) began a recipe makeover.

A hard-working group of volunteers has just updated guideline GP2 into the new edition that is being released by CLSI this month. GP2-A5 was renamed Laboratory Documents: Development and Control.1 This guideline represents the ultimate low carb diet for laboratory policy, process, and procedure documents. Laboratories that actually went on this document diet and have seen the results contributed the examples in the appendices. You won’t believe the difference! Talk about slimmed down!

As individuals, we all know that we should eat better and get more fit and trim; likewise, we all know that our laboratory documents should follow the same advice. However, it’s what we do about what we know that actually makes the difference.
“Every last bit of food that is bad must be banished
till all the additional ounces have vanished…”
