Background: The vasoactive-inotropic score (VIS) predicts mortality and morbidity after paediatric cardiac surgery. Here we examined whether VIS also predicted outcome in adults after cardiac surgery, and compared predictive capability between VIS and three widely used scoring systems. Methods: This single-centre retrospective cohort study included 3213 cardiac surgery patients. Maximal VIS (VIS max ) was calculated using the highest doses of vasoactive and inotropic medications administered during the first 24 h postsurgery. We established five VIS max categories: 0e5, >5e15, >15e30, >30e45, and >45 points. The predictive accuracy of VIS max was evaluated for a composite outcome, which included 30-day mortality, mediastinitis, stroke, acute kidney injury, and myocardial infarction. Results: VIS max showed good prediction accuracy for the composite outcome [area under the curve (AUC), 0.72; 95% confidence interval (CI), 0.69e0.75]. The incidence of the composite outcome was 9.6% overall and 43% in the highest VIS max group (>45). VIS max predicted 30-day mortality (AUC, 0.76; 95% CI, 0.69e0.83) and 1-yr mortality (AUC, 0.70; 95% CI, 0.65e0.74). Prediction accuracy for unfavourable outcome was significantly better with VIS max than with Acute Physiology and Chronic Health Evaluation II (P¼0.01) and Simplified Acute Physiological Score II (P¼0.048), but not with the Sequential Organ Failure Assessment score (P¼0.32). Conclusions: In adults after cardiac surgery, VIS max predicted a composite of unfavourable outcomes and predicted mortality up to 1 yr after surgery.

Of very old ICU patients, 62% were alive 1 year after ICU admission and 78% of the survivors had a functional status comparable to the premorbid situation. A poor PFS doubled the odds of death within a year. Knowledge of PFS improved the prediction of 1-year mortality.

The decision to limit life-sustaining treatment (LST) in the intensive care unit (ICU) is made when the patient's recovery is not anticipated, despite aggressive treatment. The practice of making such decisions in ICUs varies across geographical regions. 1 In some countries, endof-life practices are more common; a decision to withhold/withdraw LST has been reported in approximately 15% of ICU patients in the United States of America and Australia (range, 13%-18% and 12%-19%) and 11% in Europe (range 8%-15%). 2-4 In other countries, the practice is less frequent (eg 3% in South Asia) 2 and some regions do not have regulations regarding end-of-life care. 5 Decisions to limit LST are difficult because they are based on the subjective judgment of the treatment team, and these judgments can

Background Poor premorbid functional status (PFS) is associated with mortality after intensive care unit (ICU) admission in patients aged 80 years or older. In the subgroup of very old ICU patients, the ability to recover from critical illness varies irrespective of age. To assess the predictive ability of PFS also among the patients aged 85 or older we set out the current study. Methods In this nationwide observational registry study based on the Finnish Intensive Care Consortium database, we analysed data of patients aged 85 years or over treated in ICUs between May 2012 and December 2015. We defined PFS as good for patients who had been independent in activities of daily living (ADL) and able to climb stairs and as poor for those who were dependent on help or unable to climb stairs. To assess patients’ functional outcome one year after ICU admission, we created a functional status score (FSS) based on how many out of five physical activities (getting out of bed, moving indoors, dressing, climbing stairs, and walking 400 m) the patient could manage. We also assessed the patients’ ability to return to their previous type of accommodation. Results Overall, 2037 (3.3% of all adult ICU patients) patients were 85 years old or older. The average age of the study population was 87 years. Data on PFS were available for 1446 (71.0%) patients (good for 48.8% and poor for 51.2%). The one-year mortalities of patients with good and those with poor PFS were 29.2% and 50.1%, respectively, p < 0.001. Poor PFS increased the probability of death within 12 months, adjusted odds ratio (OR), 2.15; 95% confidence interval (CI) 1.68–2.76, p < 0.001. For 69.5% of survivors, the FSS one year after ICU admission was unchanged or higher than their premorbid FSS and 84.2% of patients living at home before ICU admission still lived at home. Conclusions Poor PFS doubled the odds of death within one year. For most survivors, functional status was comparable to the premorbid status.
