Real-World Retrospective Exposure-Crossover Study of 70K+ Patients Reveals Most Frequent Complications Associated with COVID-19

Real-World Retrospective Exposure-Crossover Study of 70K+ Patients Reveals Most Frequent Complications Associated with COVID-19

A sizable retrospective study involving the University of Buffalo, Aetion, Inc., HealthVerity, Inc. and the University of Toronto confirms a significant number of complications associated with COVID-19.  Published in the Canadian Medical Association Journal (CMAJ), the team used de-identified outpatient and inpatient medical claims from American health databases to identify 70,288 patients who were infected with SARS-CoV-2, the virus behind COVID-19. Covering a duration from March 1 to April 30, 2020 over half of the health visits involved hospitalization, with about 5% of the total admitted into intensive care. With a median age of 65 and 55.8% female the authors studied a plethora of medical codes targeting those that increased in number post pandemic onset. Sure enough this real world evidence (RWE)-based study found that the most frequent complications associated with COVID-19 included pneumonia, respiratory failure, kidney failure and sepsis or systemic inflammation. These findings aligned with other observations. Overall, the risk associated with a patient with COVID-19 succumbing to these more serious ailments equaled 27.6% for pneumonia, 22.6% for respiratory failure, 11.8% kidney failure and 10.4% associated with sepsis or systemic inflammation.

Additionally these researchers found other real world evidence, although rare in association with COVID-19,  such as a range of other conditions associated with COVID-19 such as collapsed lung, blood clotting disorders and heart inflammation. COVID-19 isn’t associated with a higher risk of stroke according to this study. The study can be found here

Investigator Point of View

Dr. William Murk, Jacobs School of Medicine & Biological Sciences, University of Buffalo, reported, “Understanding the full range of associated conditions can aid in prognosis, guide treatment decisions and better inform patients as to their actual risks for the variety of COVID-19 complications reported in the literature and media.”

  1. What we need now is a more current study on the same magnitude! Curious what the hospitalization rate would be at.
