Chapter 1: Understanding COVID-19 Mortality Rates

The death rate associated with COVID-19 shows significant variation based on different studies. Early on, Chinese researchers reported a mortality rate of 62%, while studies conducted in Seattle indicated a 50% rate, and Lombardy reported 26%. These figures typically emerged from single-center studies and did not provide a comprehensive overview of COVID-19 mortality and its associated risk factors.

To gain a broader perspective, the STOP-COVID study (Study of the Treatment and Outcomes in Critically Ill Patients With COVID-19) was initiated. This research focuses on COVID-19 patients across multiple hospital intensive care units (ICUs) in the United States, examining demographics, preexisting conditions, organ failure, treatments, and outcomes.

The findings from this study, published in JAMA, involved 2,215 adults with confirmed COVID-19 who were admitted to ICUs at 65 hospitals from March 4 to April 4, 2020, during the early phase of the pandemic. The overall mortality rate observed was 35.4% within 28 days of hospitalization. While 37.2% of the patients were discharged alive within that time frame, 27.4% remained hospitalized after 28 days. Mortality rates varied significantly among hospitals, ranging from as low as 6.6% to as high as 80.8%.

A statistical analysis was performed to identify factors contributing to mortality. As expected, older age correlated with a heightened risk of death; individuals aged 80 and over were nearly 12 times more likely to die compared to those under 40. Additionally, men had a 1.5 times greater likelihood of dying than women, and individuals with a body mass index (BMI) of 40 or more faced the same increased risk compared to those with a BMI under 25. Furthermore, patients with preexisting heart conditions, active cancers, low oxygen saturation, or liver and kidney dysfunction exhibited an elevated risk of death.

One surprising aspect of the research was that conditions like hypertension and diabetes did not correlate with an increased mortality risk. This was unexpected, as there have been numerous instances of young, otherwise healthy individuals becoming severely ill due to diabetes. However, many of those affected ultimately survived, suggesting a possible alignment between personal experiences and the study's findings.

Additionally, it was encouraging to note that although nearly one-third of critically ill patients were Black, race (excluding White) was not linked to an increased risk of death. If these results hold true, it would be a positive development, as there should be no disparity in death rates from COVID-19 between Black and White Americans.

By the conclusion of the study, 39.5% of patients had died, underscoring the lethal nature of COVID-19 in severe cases. This highlights the critical need for ongoing vigilance against this virus. It is vital to maintain social distancing, practice thorough hand hygiene, avoid large gatherings, and most importantly, consistently wear masks in public spaces.

Although the virus has taken a firm grip on our nation, it is not unbeatable. With collective effort and solidarity, we can defeat this virus once and for all.
