Abstract
Background: In medical science, the probability of survival is a crucial index used to assess patient outcomes. This study aims to estimate the survival probability of patients diagnosed with COVID-19.
Materials and Methods: In a historical cohort study, the Kaplan-Meier method was used to assess the survival probability of 4,372 COVID-19 patients treated at Dr. Masih Daneshvari Hospital in Tehran during the pandemic.
Results: The study results indicated that 199 patients (4.6%) died during the treatment, while 4,173 patients (95.4%) were censored. The daily survival probability estimation for COVID-19 patients revealed that the highest and lowest survival probabilities within 100 days from disease onset were 96% and 55%, respectively. Additionally, the survival probabilities on the 20th, 50th, 70th, and 90th days from the onset of disease and treatment were 92%, 70%, 63%, and 61%, respectively.
Conclusion: Estimating the survival probability of COVID-19 patients offers clinicians valuable insights into mortality rates and the effectiveness of common therapeutic strategies in treating the disease.
