RESUMO
BACKGROUND AND OBJECTIVES: In March 2020, the World Health Organization announced a state of emergency due to the appearance of a pandemic caused by the Coronavirus 2 (SARS-CoV-2), a severe acute respiratory syndrome, known as Covid-19. Most governments chose to implement precautionary measures, e.g., physical distancing and use of protective devices, which can in part limit the transmission of the virus. However, the healthcare system experienced numerous structural problems in managing the Covid-19 patients given the limited human and technical resources in critical areas, such as the intensive care units (ICUs). Different therapeutic solutions should therefore be assessed, which can potentially minimize the negative impact of the disease on patients, favoring their recovery and optimizing healthcare resources. The objective of this study is to simulate the impact of remdesivir treatment on the pandemic course in the long term. METHODS: A forecasting model is designed to estimate how remdesivir would impact the ICU capacity and the healthcare costs from the hospital perspective when managing COVID-19 patients. This model is applied in the Portuguese context with a 20-week projection starting on May 1st and concluding on September 18th, 2021. The data inputs were carefully collected by consulting different sources, such as published global literature, official governmental reports, and available infectious diseases databases, i.e., Our World in Data, Portuguese Ministry of Health, and experts' opinions. RESULTS: The model showed that the introduction of remdesivir-based treatment in patients with Covid-19 pneumonia requiring supplemental oxygen therapy generates a significant reduction in both the number of ICU admissions and deaths, which would produce more than 23 million in cost savings and avoid more than 261 ICUs admissions and 166 deaths. CONCLUSION: It is demonstrated that alternative treatments such as remdesivir can reduce both the health burden for healthcare facilities, optimize their management, and improve patients' clinical conditions. However, the model is centered on Rt values, which cannot be generalized to the entire country; hence, the results of this research should be considered as a "hypothetical study".
