The Development of Living, Rapid Practice Points: Summary of Methods From the Scientific Medical Policy Committee of the American College of Physicians.

In response to the COVID-19 pandemic, the Scientific Medical Policy Committee (SMPC) of the American College of Physicians (ACP) began developing "practice points" to provide clinical advice based on the best available evidence for the public, patients, clinicians, and public health professionals. As one of the first organizations in the United States to develop evidence-based clinical guidelines, ACP continues to lead and advance the science of evidence-based medicine by implementing new methods to rapidly publish practice points and maintain them as living advice that regularly assesses and incorporates new evidence. The overarching aim of practice points is to answer targeted key questions for which there is a timely need to synthesize evidence for decision making. The SMPC believes these methods can potentially be adapted to address various clinical and public health topics beyond the COVID-19 pandemic. This article presents an overview of the SMPC's living, rapid practice points development process, which includes a rapid systematic review, use of the GRADE (Grading of Recommendations Assessment, Development and Evaluation) method, use of stringent policies on the disclosure of interests and management of conflicts of interest, incorporating a public (nonclinician) perspective, and maintenance of the documents as living through ongoing surveillance and synthesis of new evidence as it emerges.

What Is the Antibody Response and Role in Conferring Natural Immunity After SARS-CoV-2 Infection? Rapid, Living Practice Points From the American College of Physicians (Version 1).

DESCRIPTION: The widespread availability of SARS-CoV-2 antibody tests raises important questions for clinicians, patients, and public health professionals related to the appropriate use and interpretation of these tests. The Scientific Medical Policy Committee (SMPC) of the American College of Physicians developed these rapid, living practice points to summarize the current and best available evidence on the antibody response to SARS-CoV-2 infection, antibody durability after initial infection with SARS-CoV-2, and antibody protection against reinfection with SARS-CoV-2. METHODS: The SMPC developed these rapid, living practice points based on a rapid and living systematic evidence review done by the Portland VA Research Foundation and funded by the Agency for Healthcare Research and Quality. Ongoing literature surveillance is planned through December 2021. When new studies are identified and a full update of the evidence review is published, the SMPC will assess the new evidence and any effect on the practice points. PRACTICE POINT 1: Do not use SARS-CoV-2 antibody tests for the diagnosis of SARS-CoV-2 infection. PRACTICE POINT 2: Antibody tests can be useful for the purpose of estimating community prevalence of SARS-CoV-2 infection. PRACTICE POINT 3: Current evidence is uncertain to predict presence, level, or durability of natural immunity conferred by SARS-CoV-2 antibodies against reinfection (after SARS-CoV-2 infection).
