Testing guidelines during times of crisis: challenges and limitations of developing rapid and living guidelines.

BACKGROUND

The start of the COVID-19 pandemic presented a situation in which there was an urgent need for decision-making that relates to diagnosis, but the evidence was lacking, of low certainty or constantly changing. Rapid and living guideline development methods were needed and had to be applied to rigorous guideline approaches, such as the Grading of Recommendations Assessment, Development, and Evaluation approach.

OBJECTIVES

To describe the process of developing rapid diagnosis guidelines when there is limited and imperfect available data at the time of crisis.

SOURCES

Case example from four Infectious Disease Society of America COVID-19 diagnostic guidelines.

CONTENT

As the world was experiencing panic with COVID-19, there were serious doubts about the feasibility of following a rigorous process for guideline development when timeliness was of extreme value. The Infectious Disease Society of America guideline panels supported by several methodologists strongly believed that at times of crisis, it is more important than ever to follow a rigorous process. The panel adopted a rapid and living systematic review methodology and applied the Grading of Recommendations Assessment, Development and Evaluation approach to four diagnosis guidelines despite the challenges of scarce and dynamic evidence. We describe the methodological details of the rapid and living approach (data extraction, meta-analysis, Evidence to Decision framework, and recommendation development), the challenge of resources, the challenge of scarce evidence, the challenge of rapidly changing evidence, as well as 'wins' from the Infectious Disease Society of America experience.

IMPLICATIONS

Mitigation of pandemics relies on rapid and accurate diagnosis, which is challenged by many knowledge gaps. This necessitates emerging evidence is rapidly incorporated in a living fashion with several decisional and contextual factors to ensure the best public health strategies and care for patients. This process must be systematic and transparent for developing trustworthy guidelines and should be supported by all stakeholders, including researchers, editors, publishers, professional societies, and policymakers.
