In March 2020, as deaths from COVID-19 surged across the world, we orchestrated the largest nationwide study of critically ill patients with COVID-19 assembled to date in the United States. This grassroots, unfunded project was made possible with the help of over 400 collaborators across the US, including research coordinators, medical students, residents, fellows, and attendings across a variety of specialties. Together, we gathered detailed, patient-level data from over 5,000 patients with COVID-19 admitted to ICUs at 68 sites. This was the start of STOP-COVID (Study of the Treatment and Outcomes in Critically Ill Patients With COVID-19).

All data were painstakingly extracted by manual chart review and entered into a centralized online database. Here is a snapshot of a few of our recent studies.

 *In the first manuscript, we examined risk factors for 28-day mortality among 2215 critically ill patients. We found that 784 (35.4%) patients died within 28 days, with wide interhospital variation in both treatments (e.g., proning) and outcomes (e.g., death). Factors associated with death included older age, male sex, morbid obesity, coronary artery disease, cancer, acute organ dysfunction, and, notably, admission to a hospital with fewer ICU beds. Admission to a hospital with <50 versus ≥100 ICU beds associated with a >3-fold increased risk of death in multivariable analyses. Results are published in JAMA Internal Medicine


*We utilized a ‘target trial emulation’ approach to test whether early use of tocilizumab decreases mortality in critically ill patients with COVID-19. Of 3924 patients included in our analysis, 433 (11%) were treated with tocilizumab in the first 2 days of ICU admission, and these patients had a 30% lower risk of death compared with those not treated with tocilizumab. The beneficial effect of tocilizumab on survival was consistent across categories of age, sex, and illness severity. Notably, we found that patients with a more rapid disease trajectory, defined as three days or fewer from symptom onset to ICU admission, appeared to benefit from tocilizumab to a greater extent than patients with a slower disease trajectory(60% lower risk of death). Results are published in JAMA Internal Medicine with an accompanying editorial.


*We studied risk factors for acute kidney injury treated with renal replacement therapy (AKI-RRT) in 3099 patients. We identified several patient-level risk factors for AKI-RRT, including chronic kidney disease, male sex, non-White race, and higher D-dimer. Among patients who survived to hospital discharge, one in three remained RRT-dependent at discharge, and one in six remained RRT dependent 60 days after ICU admission. Results are published in JASN 

*We investigated the incidence, risk factors, and outcomes associated with in-hospital cardiac arrest and CPR in 5019 patients. We found that 14% of patients had in-hospital cardiac arrest, of whom 57% received CPR. Patients who had in-hospital cardiac arrest were older, had more comorbidities, and were more likely to be admitted to a hospital with a smaller number of ICU beds compared with those who did not have in-hospital cardiac arrest. Cardiac arrest was associated with poor survival, with only 12% surviving to hospital discharge, and even fewer (only 7%) surviving to hospital discharge with no more than mildly impaired neurologic function. Results are published in BMJ 

*We examined the clinical course of critically ill patients with COVID-19 with and without pre-existing kidney disease. Dialysis patients had a shorter time from symptom onset to ICU admission compared with other groups, and were more likely to present with altered mental status on admission. Half the patients with CKD died within 28 days of ICU admission versus 35% of patients without CKD, with dialysis patients having the highest risk of death. Results are published in AJKD.


*In a propensity score matched analysis, we examined the association between solid organ transplant (SOT) status with death and other clinical outcomes. Receipt of mechanical ventilation, development of acute respiratory distress syndrome, and receipt of vasopressors were similar between SOT recipients and non-recipients, as was the risk of 28-day mortality. Results are published in AJT.

Data collected by the STOP-COVID collaborators has provided valuable insight into the risk factors, outcomes, and treatment strategies for critically ill patients with COVID-19. This is just the beginning… more to come as we analyze more data.

Concept Map: Glomerular Diseases with Immunotherapy

 A recent systematic review discussed GNs cases seen with immune checkpoint inhibitors. This concept map( part of the paper) is displayed here.

The above review was done before the listed two articles were published 

Even after addition of the above cases, vasculitis would still be the most common and podocytopathies following that. C3 GN would be the third most common.
