- BACKGROUND: Traditional models to predict intensive care outcomes do not perform well in COVID-19. We undertook a comprehensive study of factors affecting mortality and functional outcome after severe COVID-19.METHODS: In this prospective multicentre cohort study, we enrolled laboratory-confirmed, critically ill COVID-19 patients at six ICUs in the Skåne Region, Sweden, between May 11, 2020, and May 10, 2021. Demographics and clinical data were collected. ICU burden was defined as the total number of ICU-treated COVID-19 patients in the region on admission. Surviving patients had a follow-up at 90 days for assessment of functional outcome using the Glasgow Outcome Scale-Extended (GOSE), an ordinal scale (1-8) with GOSE ≥5 representing a favourable outcome. The primary outcome was 90-day mortality; the secondary outcome was functional outcome at 90 days.RESULTS: Among 498 included patients, 74% were male with a median age of 66 years and a median body mass index (BMI) of 30 kg/m 2 . Invasive mechanical ventilation was employed in 72%. Mortality in the ICU, in-hospital and at 90 days was 30%, 38% and 39%, respectively. Mortality increased markedly at age 60 and older. Increasing ICU burden was independently associated with a two-fold increase in mortality. Higher BMI was not associated with increased mortality. Besides age and ICU burden, smoking status, cortisone use, P a CO 2 >7 kPa, and inflammatory markers on admission were independent factors of 90-day mortality. Lower GOSE at 90 days was associated with a longer stay in the ICU. CONCLUSION: In critically ill COVID-19 patients, the 90-day mortality was 39% and increased considerably at age 60 or older. The ICU burden was associated with mortality, whereas a high BMI was not. A longer stay in the ICU was associated with unfavourable functional outcomes at 90 days.

- Background: The aim of this study was to identify factors predicting outcome in patients with mitochondrial disease admitted to pediatric intensive care units (PICU). Methods: Retrospective study of 2434 patients (age <21 years) admitted to a PICU from 1 January 2006 through 31 March 2016 and captured in the Virtual Pediatric Systems database with ICD9 diagnosis 277.87, disorders of mitochondrial metabolism. Factors influencing mortality and prolonged length of stay (≥14 days) were analyzed using logistic regression. Results: Predictors independently affecting mortality (adjusted odds ratios and 95% confidence intervals, p < 0.05): age 1–23 months 3.4 (1.7–6.6) and mechanical ventilation 4.7 (2.6–8.6) were risk factors; post-operative 0.2 (0.1–0.6), readmission 0.5 (0.3–0.9), and neurologic reason for admittance 0.3 (0.1–0.9) were factors reducing risk. Predictors affecting prolonged length of stay: mechanical ventilation 7.4 (5.2–10.3) and infectious reason for admittance 2.0 (1.3–3.2) were risk factors, post-operative patients 0.3 (0.2–0.5) had lower risk. The utility of PRISM and PIM2 scores in this patient group was evaluated. Conclusions: The single most predictive factor for both mortality and prolonged length of stay is the presence of mechanical ventilation. Age 1–23 months is a risk factor for mortality, and infectious reason for admittance indicates risk for prolonged length of stay. Impact: Presence of mechanical ventilation is the factor most strongly associated with negative outcome in patients with mitochondrial disease in pediatric intensive care.Age 1–23 months is a risk factor for mortality, and infectious reason for admittance indicates risk for prolonged length of stayPRISM3 and PIM2 are not as accurate in patients with mitochondrial disease as in a mixed patient population.
