Objective: o evaluate the length of stay and the risk of death among COVID-19 patients using invasive medical devices while admitted to intensive care units. Method: This was a quantitative, longitudinal study with a retrospective cohort design, based on data from 257 medical records of adult patients admitted to intensive care between 2020 and 2021 at a university hospital. Data collection was carried out in 2022 over a period of eight months using a structured collection instrument. The results were tabulated in Excel 2010. and statistical analyses were performed using the Statistical Package for the Social Sciences, version 20.0. Survival analysis was conducted, including calculation of the Hazard Ratio. Results: Prolonged use of invasive medical devices was observed in COVID-19 patients during their stay in the intensive care unit, with a particular prevalence of central venous catheters and nasoenteric tubes. This group also experienced longer use of orotracheal tubes. The use of invasive medical devices on the seventh day of hospitalization increased and was strongly associated with a higher risk of death among COVID-19 patients. Conclusion: COVID-19 patients used more hospital medical devices, with orotracheal tubes, central venous catheters, indwelling urinary catheters, and nasoenteric tubes being the most common. These devices were associated with longer durations of use and a higher risk of death compared to patients without a COVID-19 diagnosis. Rates of mechanical ventilation and oxygen therapy were also higher in the COVID-19 grou.
