Background: The surge in patients during the COVID-19 pandemic has exacerbated the looming problem of staff shortage in German ICUs possibly leading to worse outcomes for patients. Methods: Within the German Evidence Ecosystem CEOsys network, we conducted an online national mixed-methods survey assessing the standard of care in German ICUs treating patients with COVID-19. Results: A total of 171 German ICUs reported a median ideal number of patients per intensivist of 8 (interquartile range, IQR = 3rd quartile - 1st quartile = 4.0) and per nurse of 2.0 (IQR = 1.0). For COVID-19 patients, the median target was a maximum of 6.0 (IQR = 2.0) patients per intensivist or 2.0 (IQR = 0.0) patients per nurse. Targets for intensivists were rarely met by 15.2% and never met by 3.5% of responding institutions. Targets for nursing staffing could rarely be met in 32.2% and never in 5.3% of responding institutions.Conclusions: Shortages of staffing in the critical care setting are eminent during the COVID-19 pandemic and might not only negatively affect patient outcomes, but also staff wellbeing and healthcare costs. A joint effort that scrutinizes the demands and structures of our health care system seems fundamental to be prepared for the future.

Objective.The aim of this retrospective study was to assess the suitability of routine data gathered with a computerized anesthesia record keeping system in investigating predictors for intraoperative hypoxemia (SpO2 < 90%) during one-lung ventilation (OLV) in pulmonary surgery. Methods.Over a four-year period data of 705 patients undergoing thoracic surgery (pneumonectomy: 78; lobectomy: 292; minor pulmonary resections: 335) were recorded online using an automated anesthesia record-keeping system. Twenty-six patient-related, surgery-related and anesthesia-related variables were studied for a possible association with the occurrence of intraoperative hypoxemia during OLV. Data were analyzed using univariate and multivariate (logistic regression) analysis (p< 0.05). The model’s discriminative power on hypoxemia was checked with a receiver operating characteristic (ROC) curve. Calibration was tested using the Hosmer-Lemeshow goodness-of-fit test. Results.An intraoperative incidence of hypoxemia during OLV was found in 67 patients (9.5%). Using logistic regression with a forward stepwise algorithm, body-mass-index (BMI, p= 0.018) and preoperative existing pneumonia (p= 0.043) could be detected as independent predictors having an influence on the incidence of hypoxemia during OLV. An acceptable goodness-of-fit could be observed using cross validation for the model (C = 8.21, p= 0.370, degrees of freedom, df 8; H = 3.21, p= 0.350, df 3), the discriminative power was poor with an area under the ROC curve of 0.58 [0.51–0.66]. Conclusions.In contrast to conventional performed retrospective studies, data were directly available for analyses without any manual intervention. Due to incomplete information and imprecise definitions of parameters, data of computerized anesthesia records collected in routine are helpful but not satisfactory in evaluating risk factors for hypoxemia during OLV.
