Number of intensivists per bed is associated with efficiency of Dutch intensive care units
PURPOSE: To measure efficiency in Intensive Care Units (ICUs) and to determine which organizational factors are associated with ICU efficiency, taking confounding factors into account. MATERIALS AND METHODS: We used data of all consecutive admissions to Dutch ICUs between January 1, 2016 and January 1, 2019 and recorded ICU organizational factors. We calculated efficiency for each ICU by averaging the Standardized Mortality Ratio (SMR) and Standardized Resource Use (SRU) and examined the relationship between various organizational factors and ICU efficiency. We thereby compared the results of linear regression models before and after covariate adjustment using propensity scores. RESULTS: We included 164,399 admissions from 83 ICUs. ICU efficiency ranged from 0.51-1.42 (average 0.99, 0.15 SD). The unadjusted model as well as the propensity score adjusted model showed a significant association between the ratio of employed intensivists per ICU bed and ICU efficiency. Other organizational factors had no statistically significant association with ICU efficiency after adjustment. CONCLUSIONS: We found marked variability in efficiency in Dutch ICUs. After applying covariate adjustment using propensity scores, we identified one organizational factor, ratio intensivists per bed, having an association with ICU efficiency
Comparison of patient characteristics and long-term mortality between transferred and non-transferred COVID-19 patients in Dutch intensive care units: A national cohort study.
BACKGROUND: COVIDâ19 patients were often transferred to other intensive care units (ICUs) to prevent that ICUs would reach their maximum capacity. However, transferring ICU patients is not free of risk. We aim to compare the characteristics and outcomes of transferred versus nonâtransferred COVIDâ19 ICU patients in the Netherlands. METHODS: We included adult COVIDâ19 patients admitted to Dutch ICUs between March 1, 2020 and July 1, 2021. We compared the patient characteristics and outcomes of nonâtransferred and transferred patients and used a Directed Acyclic Graph to identify potential confounders in the relationship between transfer and mortality. We used these confounders in a Cox regression model with left truncation at the day of transfer to analyze the effect of transfers on mortality during the 180âdays after ICU admission. RESULTS: We included 10,209 patients: 7395 nonâtransferred and 2814 (27.6%) transferred patients. In both groups, the median age was 64âyears. Transferred patients were mostly ventilated at ICU admission (83.7% vs. 56.2%) and included a larger proportion of lowârisk patients (70.3% vs. 66.5% with mortality risk <30%). After adjusting for age, APACHE IV mortality probability, BMI, mechanical ventilation, and vasoactive medication use, the hazard of mortality during the first 180âdays was similar for transferred patients compared to nonâtransferred patients (HR [95% CI]Â =Â 0.99 [0.91â1.08]). CONCLUSIONS: Transferred COVIDâ19 patients are more often mechanically ventilated and are less severely ill compared to nonâtransferred patients. Furthermore, transferring critically ill COVIDâ19 patients in the Netherlands is not associated with mortality during the first 180âdays after ICU admission
