COVID-19 Published Guidelines and Reviews

Following declarations from the US Department of Health and Human Services and World Health Organization ending the COVID-19 Public Health Emergency, the IARS COVID-19 Scientific Advisory Board (SAB) concluded its review of the scientific literature about SARS-CoV-2 in August. The SAB has reviewed more than 3,100 journal articles and published 1,076 article reviews over the past 42 months. It has been an enormous commitment from the SAB, and the IARS owes our dedicated physician volunteers a huge debt of gratitude for their unwavering participation in this initiative.

The COVID-19 Scientific Advisory Board has compiled and examined published guidelines and reviews on COVID-19 and have provided a collection of those most helpful and relevant for frontline providers below.

International Society of Thrombosis and Hemostasis
Claim CME ButtonGood practice statements for antithrombotic therapy in the management of COVID-19: Guidance from the SSC of the ISTH. 7/29/22. J Thromb Haemost. Clin Infect Dis.
This article is a set of best practice statements for deep vein thrombosis prophylaxis and treatment with COVID-19 from the International Society of Thrombosis and Hemostasis. It is not based upon a systematic review but expert opinion. While much of this is similar to prior guidelines, the special considerations section covering pregnancy, pediatrics, chronic kidney disease, obesity and heparin-induced thrombocytopenia without thrombosis are of value.

ISTH guidelines for antithrombotic treatment in COVID-19. 7/29/22. Schulman S. J Thromb Haemost.
This article is a systematic review and guidelines for deep vein thrombosis prophylaxis with COVID-19 from the International Society of Thrombosis and Hemostasis. It was performed by a panel of experts. Among noncritically ill patients hospitalized for COVID-19, the panel gave a strong recommendation (a) for use of prophylactic dose of low molecular weight heparin or unfractionated heparin (LMWH/UFH) (COR 1); (b) for select patients in this group, use of therapeutic dose LMWH/UFH in preference to prophylactic dose (COR 1); but (c) against the addition of an antiplatelet agent (COR 3). Nine additional recommendations are made. The review is comprehensive and current, and the recommendations are graded. Figure 2 is useful as it summarizes the findings.

Antibody evasion by SARS-CoV-2 Omicron subvariants BA.2.12.1, BA.4, & BA.5. 7/5/22. Wang Q. Nature.
The authors performed systematic antigenic analyses of Omicron subvariants finding BA.2.12.1 only modestly (1.8-fold) more resistant to sera from vaccinated and boosted individuals than BA.2. However, BA.4/5 is substantially (4.2-fold) more resistant and thus more likely to lead to vaccine breakthrough infections. Among therapeutic antibodies authorized for clinical use, only bebtelovimab retains full potency against both BA.2.12.1 and BA.4/5. Serum neutralization assays used sera from persons who received three shots of mRNA vaccines, others who received mRNA vaccines before or after non-Omicron infection, vaccinated patients with BA.1 or BA.2 breakthrough infection as well as pseudoviruses containing point mutations. The Omicron SARS-CoV-2 lineage continues to evolve, successively yielding subvariants that are both more transmissible and more evasive to antibodies.
SAB Comment: Bebtelovimab (Eli Lilly) has been authorized under EUA since 2/22 for mild-to-moderate COVID-19 in patients older than 12 years and weighing at least 40 kg who are at high risk for progression to severe disease. It is given as a single IV injection, within 7 days of symptom onset. Readers may access current NIH Therapeutic Guidelines, including use of bebtelovimab, on the IARS COVID-19 Published Guidelines and Reviews web page.

American Society of Anesthesiologists (ASA) and Anesthesia Patient Safety Foundation (APSF)
ASA and APSF Statement on Perioperative Testing for the COVID-19 Virus. 6/16/22. ASA & APSF.
SAB Comment: Readers are encouraged to review the full publication. A few key points, including the potential use of community transmission metrics to guide the use of universal testing, are summarized below:

SCREENING: All patients should be screened for COVID-19 symptoms and for close contact to someone diagnosed with COVID-19 in the past 10 days.

TESTING: The use and limitations of PCR for SARS-CoV-2 testing are reviewed. If a patient tests positive, elective surgical procedures should be delayed. Antibody testing is not recommended for perioperative screening.

COMMUNITY TRANSMISSION METRICS: Two metrics, based on cases/100K in the last 7 days and % test positivity in the last 7 days, are available by community on the CDC website. When levels are graded substantial to high, universal use of PCR testing is recommended. If community transmission is low to moderate, the patient is asymptomatic, up-to-date in vaccination and having a lower-risk procedure, facilities could consider a more permissive approach to perioperative testing.

A number of specific situations are reviewed, including cases of immunosuppressed or other patients likely to carry transmissible virus for longer than 10 days after infection.
