The following is a summary of the most recent information posted to our COVID-19 portal.


Webinar: Open Science — COVID-19 and Beyond: October 27, 2020

  • Join us for a talk about the many scientific publishing shifts happening in connection with the pandemic.
  • We’ll be discussing these changes and exploring their implications for access to scientific research and evidence synthesis.
  • Speakers include Leslie Weir (Librarian and Archivist of Canada; Chair, Open Science Roadmap Advisory Committee) and Dr. Margaret Sampson (Manager of Library Services, Children’s Hospital of Eastern Ontario).
  • Please register to participate (there is no cost).

CADTH Virtual Symposium: November 9 to 10, 2020 — Call for Abstracts on COVID-19 Topics

You still have time to submit your abstracts on COVID-19 topics for presentation at the 2020 Virtual CADTH Symposium. Follow the details at the above link and submit your abstract by Wednesday, October 7, 2020.


Ongoing Trials of Plasma-Based Therapies for the Treatment of COVID-19

  • This report provides information on ongoing randomized controlled trials of intravenous immune globulin and hyperimmune globulin that are being investigated for the management of COVID-19.
  • It will be updated every month.
  • Ongoing trials of convalescent plasma are addressed in separate CADTH reports.

Ongoing Trials for Drugs in the Prevention and Treatment of COVID-19

  • This report provides information on ongoing randomized controlled trials of drugs being investigated to treat or prevent COVID-19.
  • It will be updated every two weeks.
  • Ongoing trials of vaccines and plasma-based therapies are addressed in separate CADTH reports.

Convalescent Plasma Therapy for the Treatment of COVID-19: A Review of Clinical Effectiveness

  • Convalescent plasma therapy is an intervention where plasma is collected from recovered COVID-19 patients, in the hope that the disease-specific antibodies can help the recipient recover from COVID-19.
  • Evidence on the effectiveness of convalescent plasma therapy for the treatment of COVID-19 is still in the early stages.
  • This report summarizes the current evidence and it will be updated monthly as a living review.

Wearable Devices for Monitoring and Detecting COVID-19 Symptoms

  • Wearable devices — such as watches, arm bands, and patches — may help reduce the spread of COVID-19.
  • Wearable technologies could improve early symptom detection, especially through close monitoring of contacts.
  • They may also safely monitor patients from a distance and limit health care worker exposure.
  • This bulletin explores different wearable technologies in the context of the COVID-19 pandemic.

Non-Invasive Ventilation With Helmets for Acute Respiratory Distress Due to COVID-19

  • This Health Technology Update newsletter describes patient helmets, also known as helmet masks, and their potential use in COVID-19 infection control.
  • These helmets are designed to reduce the risk of COVID-19 transmission from infected patients to health care providers and other patients.
  • The newsletter provides a background to the technology, target populations, cost and availability, current clinical evidence, and potential implications for future research.
  • This technology was identified through the CADTH Horizon Scanning Service as a topic of potential interest to health care decision-makers in Canada.
