Study Reveals Alarming COVID-19 Mortality Rates and Key Risk Factors in U.S. Hospitals During Delta Wave
  • The 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.
