Defining the Path Forward: Guidance for Laboratory Medicine Guidelines

Established clinical guidelines require consistent and transparent development processes. Prior research has shown that guidelines lacking standardization may lead to inconsistent clinical practices. The need for a structured approach became evident in 1997 when the NACB first introduced a Standard Operating Procedure (SOP). That uncertainty drove the creation of the Evidence-Based Laboratory Medicine Committee (EBLMC) in 2010 to oversee guideline development. The U.S. Institute of Medicine (IOM) also contributed by publishing reports on guideline trustworthiness and systematic reviews in 2011. These reports were part of a legislative response to improve healthcare evidence use. NACB has since updated its SOP to align with these new standards. The current focus is on refining processes to ensure guidelines remain evidence-based and widely accepted.

This article aims to describe the evolution of laboratory medicine practice guideline (LMPG) development processes. It highlights the role of the NACB and EBLMC in creating standardized guidelines. The study focuses on how the SOP has been revised to meet current evidence-based standards. The motivation stems from the need to ensure clinical guidelines are trustworthy and widely adopted. The IOM reports provided a framework for improving guideline development. The NACB has been developing one LMPG per year since 2014. Collaboration with clinical societies is a key part of this process. The study also addresses the challenges in guideline development within the U.S.

The NACB and EBLMC have used a consensus-based approach to develop clinical practice guidelines. The process includes following a Standard Operating Procedure (SOP) updated in 2014. The SOP outlines steps for guideline development, including evidence review and stakeholder input. The IOM reports provided additional guidance on systematic review standards. The EBLMC oversees guideline development in line with SOP and IOM recommendations. Collaboration with clinical societies ensures broader input and acceptance. Three LMPGs are currently in development with external partners. The methods emphasize transparency and alignment with current evidence-based practices.

The NACB has developed one LMPG per year since 2014, following updated SOP guidelines. The SOP was revised in 2014 to incorporate IOM recommendations on guideline trustworthiness. Three LMPGs are currently in various stages of development with external collaboration. The EBLMC plays a central role in overseeing guideline development processes. The SOP includes steps for systematic review and stakeholder engagement. The IOM reports provided a legislative framework for improving guideline quality. NACB and AACC have a collaborative track record in guideline development. The current LMPGs highlight practices and tools used to address guideline development challenges.

The NACB and EBLMC have established a structured process for developing laboratory medicine practice guidelines. The SOP has evolved to meet current evidence-based standards and IOM recommendations. Collaboration with clinical societies ensures broader input and acceptance of guidelines. The current LMPGs demonstrate the application of updated SOP practices. The IOM reports provided a legislative basis for improving guideline quality. The SOP includes systematic review and stakeholder engagement steps. Three LMPGs are in development with external partners. The authors suggest that these practices help address guideline development challenges in the U.S.
