![]() The predictive factors measured during ICU stay, and associated with 180-day mortality were: age per 1-year increase 1.051, 95% CI 1.033–1.068)), SAPS3 (OR per 1-point increase 1.027, 95% CI 1.011–1.044), diabetes (OR 1.546, 95% CI 1.085–2.204), neutrophils to lymphocytes ratio (OR per 1-unit increase 1.008, 95% CI 1.001–1.016), failed attempt of noninvasive positive pressure ventilation prior to orotracheal intubation (OR 1.878 (95% CI 1.124–3.140), use of selective digestive decontamination strategy during ICU stay (OR 0.590 (95% CI 0.358–0.972) and administration of low dosage of corticosteroids (methylprednisolone 1 mg/kg) (OR 2.042 (95% CI 1.205–3.460). The unadjusted overall 180-day survival rates was 59% (95% CI 56–62%). Prior to intubation, 26% received some type of noninvasive respiratory support. Severity at ICU admission, estimated by SAPS3, was 56 points. ResultsĨ68 patients were included (median age, 64 years, 56–71 years] 72% male). A predictive model was developed to estimate the probability of 180-day mortality. Secondary outcomes were length of ICU and hospital stay, and ICU and in-hospital mortality. The primary outcomes was 180-day survival after hospital admission. ![]() Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection detected in positive testing of a nasopharyngeal sample and confirmed by real time reverse-transcriptase polymerase chain reaction (rt-PCR). Participants were consecutive adults who received invasive mechanical ventilation for COVID-19. Retrospective, multicentre, national cohort study between March 8 and Apin 16 intensive care units (ICU) in Spain. We aimed to estimate 180-day mortality of patients with COVID-19 requiring invasive ventilation, and to develop a predictive model for long-term mortality. Information is lacking regarding long-term survival and predictive factors for mortality in patients with acute hypoxemic respiratory failure due to coronavirus disease 2019 (COVID-19) and undergoing invasive mechanical ventilation.
