| Popis: | Since the first epidemiological weeks in 2020, the pandemic for the new coronavirus has caused overload in the health system, since many affected patients require hospitalization due to the progression to acute respiratory distress syndrome (ARDS), heart failure, acute kidney injury and shock, the condition of which may lead to death. In this scenario, the present study aimed to analyze the survival and prognostic factors associated with mortality in patients with SRAG by COVID-19 who required ICU admission in the State of Paraiba. This is a longitudinal, observational, analytical and descriptive study, using secondary data from the individual records of hospitalized SRAG cases included in the database of the State Department of Health, containing socio-demographic, clinical and epidemiological data of each patient. Logistic regression was used to evaluate the final model that best explains the probability of the individual evolving to the outcome death. Survival functions were calculated using the Kaplan Meier method. To evaluate the factors associated with death, the hazard ratio-HR was calculated following cox's proportional risk model. The length of hospital stay until the outcome was also evaluated. A total of 2,084 observations were included. At the end of the follow-up, 479 censure (23%) and 1,605 deaths (77%) were observed. In the logistic regression stage, they were significant (at the level of 10%) in relation to the increase in the risk of death: age group over 60 (odds ratio -OR- 4.78), need for invasive ventilatory support (OR 4.17), oxygen saturation < 95% (OR 1.25), having been hospitalized in the 3rd macroregion of Paraiba (OR 1.63) and presence of immunodepression (OR 1.72). They were associated with a lower risk of death: living in a periurban area (OR 0.20) and not requiring invasive ventilatory support (0.16). The probability of survival by Kaplan-Meier was 72.1% in 5 days and 49.6% in 10 days of hospitalization. The mean length of ICU stay until death was 8.9 days. After adjustments of the variables in the Cox model, they were significant (at the level of 10%) in relation to the increase in the risk of death: age over 60 (HR 1.29), need for invasive ventilatory support (HR 1.60), oxygen saturation |
