Study Reveals Alarming COVID-19 Mortality Rates and Key Risk Factors in U.S. Hospitals During Delta Wave
September 13, 2024The research examines patient survival and prognostic factors for COVID-19 deaths in Jundiaí, São Paulo, Brazil, highlighting the significant mortality rates associated with the disease.
Among the hospitalized patients, there were 311 deaths, resulting in a mortality rate of 34.5%, underscoring the severity of COVID-19 in this cohort.
Notably, 74.7% of subjects were classified as centrally obese, and 58.2% were identified as obese based on BMI, indicating a strong link between obesity and severe COVID-19 outcomes.
Obesity is identified as a risk factor for severe COVID-19 outcomes, likely due to increased systemic inflammation and metabolic complications associated with visceral fat.
The findings highlight potential confounding and selection biases affecting the observed associations between adiposity and mortality in both COVID-19 and non-COVID-19 patients.
Led by Maniraj Neupane, M.D., Ph.D., from the National Institutes of Health Clinical Center, the research focused on the delta wave of COVID-19.
The authors suggest that further research should explore whether the high caseload risks observed during the pandemic also apply to non-COVID-19 patients in both pandemic and non-pandemic contexts.
Cox regression analysis revealed that chronic diseases and desaturation significantly increased the risk of death, emphasizing the need for targeted health interventions.
A recent study published on September 13, 2024, analyzed data from 620 U.S. hospitals, focusing on 223,380 adult inpatients with COVID-19 admitted between July and November 2021.
Key independent predictors of death included age over 60, desaturation, immunosuppression, kidney disease, hypertension, and lung disease.
The study also found that COVID-19 severity and comorbidities significantly contribute to poor outcomes, with relative risks of 3.063 and 2.123, respectively.
Geographical analysis revealed higher death prevalence in certain neighborhoods, notably Vila Municipal and Ivoturucaia, indicating disparities in health outcomes.
