Trends in short-term and 1-year mortality in very elderly intensive care patients in the Netherlands: a retrospective study from 2008 to 2014
Purpose: To describe the trends in short-term and long-term mortality in very elderly intensive care unit (ICU) patients between 2008 and 2014. Methods: A retrospective cohort study was conducted using data from the National Intensive Care Evaluation Foundation from 31 Dutch ICUs. Generalized linear mixed-effects models were used to determine the change in adjusted short-term mortality (ICU/hospital deaths) and long-term mortality (3, 6, and 12 months after ICU admission) over the period 2008-2014 in very elderly patients and in patients less than 80 years old admitted to the ICU. Results: A total of 216,196 patients admitted to 31 ICUs in the period from 2008 to 2014 were included in the study, including 28,284 (13.1%) very elderly patients (80 years or older). Follow-up data for determination of 3-, 6-, and 12-month mortality were available for, respectively, 210,005 (97.1%), 202,551 (93.7%), and 176,847 (81.8%) ICU admissions. The crude ICU and in-hospital mortality decreased, respectively, from 17.6% to 13.0% and from 30.7% to 21.0%. The annual risk-adjusted ICU and in-hospital mortality of very elderly patients (adjusted for APACHE III score, comorbidities, and admission type) decreased significantly during the study period [adjusted odds ratio 0.97 (0.95-0.99) and 0.92 (0.91-0.93), respectively]. Additionally, the annual risk-adjusted 3-, 6-, and 12-month mortality decreased significantly from 2008 to 2014 [adjusted odds ratio 0.96 (0.95-0.97), 0.96 (0.94-0.97), and 0.97 (0.95-0.98), respectively]. A similar significant annual decrease in risk-adjusted short-term and long-term mortality was observed in patients aged less than 80 years. Conclusions: Both short-term and long-term risk-adjusted mortality decreased significantly during the study period in both very elderly ICU patients and patients aged less than 80 years in the Netherlands. This study clearly shows that in our setting very elderly patients benefit almost as much as their younger counterparts from improvement in quality of care over tim
Trends in hospital and intensive care admissions in the Netherlands attributable to the very elderly in an ageing population
The Dutch population is ageing and it is unknown how this is affecting trends in the percentage of hospital and intensive care unit (ICU) admissions attributable to patients aged 80 years or older, the very elderly. We present data on the percentage of the very elderly in the general population and the percentage of hospital admissions attributable to the very elderly. We subsequently performed a longitudinal cross-sectional study on ICU admissions from hospitals participating in the National Intensive Care Evaluation registry for the period 2005 to 2014. We modeled the percentage of adult ICU admissions and treatment days attributable to the very elderly separately for ICU admissions following cardiac surgery and other reasons. The percentage of Dutch adults aged 80 years and older, increased from 4.5 % in 2005 to 5.4 % in 2014 (p-value  < 0.0001) and with this ageing of the population, the percentage of hospital admissions attributable to very elderly increased from 9.0 % in 2005 to 10.6 % in 2014 (p-value  < 0.0001). The percentage of ICU admissions following cardiac surgery attributable to the very elderly increased from 6.7 % in 2005 to 11.0 % in 2014 in nine hospitals (p-value  < 0.0001), while the percentage of treatment days attributable to this group rose from 8.6 % in 2005 to 11.7 % in 2014 (p-value = 0.0157). In contrast, the percentage of very elderly patients admitted to the ICU for other reasons than following cardiac surgery remained stable at 13.8 % between 2005 and 2014 in 33 hospitals (p-value = 0.1315). The number of treatment days attributable to the very elderly rose from 11,810 in 2005 to 15,234 in 2014 (p-value = 0.0002), but the percentage of ICU treatment days attributable to this group remained stable at 12.0 % (p-value = 0.1429). As in many European countries the Dutch population is ageing and the percentage of hospital admissions attributable to the very elderly rose between 2005 and 2014. However, the percentage of ICU admissions and treatment days attributable to very elderly remained stable. The percentage of ICU admissions following cardiac surgery attributable to this group increased between 2005 and 201

Effect of rivastigmine as an adjunct to usual care with haloperidol on duration of delirium and mortality in critically ill patients:a multicentre, double-blind, placebo-controlled randomised trial
Background Delirium is frequently diagnosed in critically ill patients and is associated with adverse outcome. Impaired cholinergic neurotransmission seems to have an important role in the development of delirium. We aimed to establish the effect of the cholinesterase inhibitor rivastigmine on the duration of delirium in critically ill patients. Methods Patients (aged 18 years) who were diagnosed with delirium were enrolled from six intensive care units in the Netherlands, and treated between November, 2008, and January, 2010. Patients were randomised (1:1 ratio) to receive an increasing dose of rivastigmine or placebo, starting at 0.75 mL (1.5 mg rivastigmine) twice daily and increasing in increments to 3 mL (6 mg rivastigmine) twice daily from day 10 onwards, as an adjunct to usual care based on haloperidol. The trial pharmacist generated the randomisation sequence by computer, and consecutively numbered bottles of the study drug according to this sequence to conceal allocation. The primary outcome was the duration of delirium during hospital admission. Analysis was by intention to treat. Duration of delirium was censored for patients who died or were discharged from hospital while delirious. Patients, medical staff, and investigators were masked to treatment allocation. Members of the data safety and monitoring board (DSMB) were unmasked and did interim analyses every 3 months. This trial is registered with ClinicalTrials.gov, number NCT00704301. Findings Although a sample size of 440 patients was planned, after inclusion of 104 patients with delirium who were eligible for the intention-to-treat analysis (n=54 on rivastigmine, n=50 on placebo), the DSMB recommended that the trial be halted because mortality in the rivastigmine group (n=12,22%) was higher than in the placebo group (n=4,8%; p=0.07). Median duration of delirium was longer in the rivastigmine group (5.0 days, IQR 2.7-14.2) than in the placebo group (3.0 days, IQR 1.0-9.3; p=0.06). Interpretation Rivastigmine did not decrease duration of delirium and might have increased mortality so we do not recommend use of rivastigmine to treat delirium in critically ill patients
Model-informed precision dosing of beta-lactam antibiotics and ciprofloxacin in critically ill patients: a multicentre randomised clinical trial
PURPOSE: Individualising drug dosing using model-informed precision dosing (MIPD) of beta-lactam antibiotics and ciprofloxacin has been proposed as an alternative to standard dosing to optimise antibiotic efficacy in critically ill patients. However, randomised clinical trials (RCT) on clinical outcomes have been lacking. METHODS: This multicentre RCT, including patients admitted to the intensive care unit (ICU) who were treated with antibiotics, was conducted in eight hospitals in the Netherlands. Patients were randomised to MIPD with dose and interval adjustments based on monitoring serum drug levels (therapeutic drug monitoring) combined with pharmacometric modelling of beta-lactam antibiotics and ciprofloxacin. The primary outcome was ICU length of stay (LOS). Secondary outcomes were ICU mortality, hospital mortality, 28-day mortality, 6-month mortality, delta sequential organ failure assessment (SOFA) score, adverse events and target attainment. RESULTS: In total, 388 (MIPD n = 189; standard dosing n = 199) patients were analysed (median age 64 [IQR 55-71]). We found no significant differences in ICU LOS between MIPD compared to standard dosing (10 MIPD vs 8 standard dosing; IRR = 1.16; 95% CI 0.96-1.41; p = 0.13). There was no significant difference in target attainment before intervention at day 1 (T1) (55.6% MIPD vs 60.9% standard dosing; p = 0.24) or at day 3 (T3) (59.5% vs 60.4%; p = 0.84). There were no significant differences in other secondary outcomes. CONCLUSIONS: We could not show a beneficial effect of MIPD of beta-lactam antibiotics and ciprofloxacin on ICU LOS in critically ill patients. Our data highlight the need to identify other approaches to dose optimisation
