ABSTRACT

OBJECTIVE: High-flow nasal oxygen (HFNO) therapy is frequently applied outside ICU setting in hypoxemic patients with COVID-19. However, safety concerns limit more widespread use. We aimed to assess the safety and clinical outcomes of initiation of HFNO therapy in COVID-19 on non-ICU wards. DESIGN: Prospective observational multicenter pragmatic study. SETTING: Respiratory wards and ICUs of 10 hospitals in The Netherlands. PATIENTS: Adult patients treated with HFNO for COVID-19-associated hypoxemia between December 2020 and July 2021 were included. Patients with treatment limitations were excluded from this analysis. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Outcomes included intubation and mortality rate, duration of hospital and ICU stay, severity of respiratory failure, and complications. Using propensity-matched analysis, we compared patients who initiated HFNO on the wards versus those in ICU. Six hundred eight patients were included, of whom 379 started HFNO on the ward and 229 in the ICU. The intubation rate in the matched cohort ( n = 214 patients) was 53% and 60% in ward and ICU starters, respectively ( p = 0.41). Mortality rates were comparable between groups (28-d [8% vs 13%], p = 0.28). ICU-free days were significantly higher in ward starters (21 vs 17 d, p < 0.001). No patient died before endotracheal intubation, and the severity of respiratory failure surrounding invasive ventilation and clinical outcomes did not differ between intubated ward and ICU starters (respiratory rate-oxygenation index 3.20 vs 3.38; Pa o2 :F io2 ratio 65 vs 64 mm Hg; prone positioning after intubation 81 vs 78%; mortality rate 17 vs 25% and ventilator-free days at 28 d 15 vs 13 d, all p values > 0.05). CONCLUSIONS: In this large cohort of hypoxemic patients with COVID-19, initiation of HFNO outside the ICU was safe, and clinical outcomes were similar to initiation in the ICU. Furthermore, the initiation of HFNO on wards saved time in ICU without excess mortality or complicated course. Our results indicate that HFNO initiation outside ICU should be further explored in other hypoxemic diseases and clinical settings aiming to preserve ICU capacity and healthcare costs.

ABSTRACT

BACKGROUND: Previous studies show positive effect of music on reducing anxiety, pain, and medication requirement. Anxiety has become a more pertinent issue in the intensive care unit (ICU) since wakefulness is preferred according to recent guidelines. Nevertheless, evidence on the effect of music in ICU patients is scarce. Therefore, we studied the effect of music intervention on anxiety in ICU patients. METHODS: A multicenter randomized clinical trial was conducted between August 2020 and December 2021 in ICU's at an academic medical centre and two regional hospitals. Adult critically ill patients were eligible when hemodynamically stable and able to communicate (Richmond agitation-sedation scale (RASS) of at least - 2). Patients in the intervention arm were offered music twice daily during three days for at least 30 min per session. Patients in the control group received standard care. The primary outcome was anxiety level assessed with the visual analogue scale for anxiety [VAS-A; range 0-10] twice daily (morning and evening). Secondary outcomes included; 6-item state-trait anxiety inventory (STAI-6), sleep quality, delirium, heart rate, mean arterial pressure, pain, RASS, medication, ICU length of stay, patients' memory and experience of ICU stay. RESULTS: 94 patients were included in the primary analysis. Music did not significantly reduce anxiety (VAS-A in the intervention group; 2.5 (IQR 1.0-4.5), 1.8 (0.0-3.6), and 2.5 (0.0-3.6) on day 1, 2, and 3 vs. 3.0 (0.6-4.0), 1.5 (0.0-4.0), and 2.0 (0.0-4.0) in the control group; p > 0.92). Overall median daily VAS-A scores ranged from 1.5 to 3.0. Fewer patients required opioids (21 vs. 29, p = 0.03) and sleep quality was lower in the music group on study day one [5.0 (4.0-6.0) vs. 4.5 (3.0-5.0), p = 0.03]. Other outcomes were similar between groups. CONCLUSIONS: Anxiety levels in this ICU population were low, and music during 3 days did not decrease anxiety. This study indicates that efficacy of music is context and intervention-dependent, given previous evidence showing decreased anxiety.

ABSTRACT

PURPOSE: COVID-19 associated pulmonary aspergillosis (CAPA) is associated with increased morbidity and mortality in ICU patients. We investigated the incidence of, risk factors for and potential benefit of a pre-emptive screening strategy for CAPA in ICUs in the Netherlands/Belgium during immunosuppressive COVID-19 treatment. MATERIALS AND METHODS: A retrospective, observational, multicentre study was performed from September 2020-April 2021 including patients admitted to the ICU who had undergone diagnostics for CAPA. Patients were classified based on 2020 ECMM/ISHAM consensus criteria. RESULTS: CAPA was diagnosed in 295/1977 (14.9%) patients. Corticosteroids were administered to 97.1% of patients and interleukin-6 inhibitors (anti-IL-6) to 23.5%. EORTC/MSGERC host factors or treatment with anti-IL-6 with or without corticosteroids were not risk factors for CAPA. Ninety-day mortality was 65.3% (145/222) in patients with CAPA compared to 53.7% (176/328) without CAPA (p = 0.008). Median time from ICU admission to CAPA diagnosis was 12 days. Pre-emptive screening for CAPA was not associated with earlier diagnosis or reduced mortality compared to a reactive diagnostic strategy. CONCLUSIONS: CAPA is an indicator of a protracted course of a COVID-19 infection. No benefit of pre-emptive screening was observed, but prospective studies comparing pre-defined strategies would be required to confirm this observation.

ABSTRACT

BACKGROUND: Restart of renal replacement therapy (RRT) after initial discontinuation of continuous RRT (CRRT) is frequently needed. The aim of the present study was to evaluate whether renal markers after discontinuation of CRRT can predict restart of RRT within 90 days. METHODS: Prospective multicenter observational study in 90 patients, alive, still on the intensive care unit at day 2 after discontinuation of CRRT for expected recovery with urinary neutrophil gelatinase-associated lipocalin (NGAL) available. The endpoint was restart of RRT within 90 days. Baseline and renal characteristics were compared between outcome groups no restart or restart of RRT. Logistic regression and receiver operator characteristic curve analysis were performed to determine the best predictive and discriminative variables. RESULTS: Restart of RRT was needed in 32/90 (36%) patients. Compared to patients not restarting, patients restarting RRT demonstrated a higher day 2 urinary NGAL, lower day 2 urine output, and higher incremental creatinine ratio (day 2/0). In multivariate analysis, only incremental creatinine ratio (day 2/0) remained independently associated with restart of RRT (OR 5.28, 95% CI 1.45-19.31, p = 0.012). The area under curve for incremental creatinine ratio to discriminate for restart of RRT was 0.76 (95% CI 0.64-0.88). The optimal cutoff was 1.49 (95% CI 1.44-1.62). CONCLUSION: In this prospective multicenter study, incremental creatinine ratio (day 2/0) was the best predictor for restart of RRT. Patients with an incremental creatinine ratio at day 2 of 1.5 times creatinine at discontinuation are likely to need RRT within 90 days. These patients might benefit from nephrological follow-up.

ABSTRACT

BACKGROUND: Prediction of successful discontinuation of continuous renal replacement therapy (CRRT) might reduce complications of over- and under-treatment. The aim of this study was to identify renal and non-renal predictors of short-term successful discontinuation of CRRT in patients in whom CRRT was stopped because renal recovery was expected and who were still in the Intensive Care Unit (ICU) at day 2 after stop CRRT. METHODS: Prospective multicentre observational study in 92 patients alive after discontinuation of CRRT for acute kidney injury (AKI), still in the ICU and free from renal replacement therapy (RRT) at day 2 after discontinuation. Successful discontinuation was defined as alive and free from RRT at day 7 after stop CRRT. Urinary neutrophil gelatinase-associated lipocalin (NGAL) and clinical variables were collected. Logistic regression and Receiver Operator Characteristic (ROC) curve analysis were performed to determine the best predictive and discriminative variables. RESULTS: Discontinuation of CRRT was successful in 61/92 patients (66%). Patients with successful discontinuation of CRRT had higher day 2 urine output, better renal function indicated by higher creatinine clearance (6-h) or lower creatinine ratio (day 2/day 0), less often vasopressors, lower urinary NGAL, shorter duration of CRRT and lower cumulative fluid balance (day 0-2). In multivariate analysis renal function determined by creatinine clearance (Odds Ratio (OR) 1.066, 95% confidence interval (CI) 1.022-1.111, p = 0.003) or by creatinine ratio (day 2/day 0) (OR 0.149, 95% CI 0.037-0.583, p = 0.006) and non-renal sequential organ failure assessment (SOFA) score (OR 0.822, 95% CI 0.678-0.996, p = 0.045) were independently associated with successful discontinuation of CRRT. The area under the curve of creatinine clearance to predict successful discontinuation was 0.791, optimal cut-off of 11 ml/min (95% CI 6-16 ml/min) and of creatinine ratio 0.819 (95% CI 0.732-0.907) optimal cut-off of 1.41 (95% CI 1.27-1.59). CONCLUSION: In this prospective multicentre study we found higher creatinine clearance or lower creatinine ratio as best predictors of short-term successful discontinuation of CRRT, with a creatinine ratio of 1.41 (95% CI 1.27-1.59) as optimal cut-off. This study provides a practical bedside tool for clinical decision making.

ABSTRACT

INTRODUCTION: Acute kidney injury (AKI) requiring renal replacement therapy (RRT) is associated with high mortality. The creatinine-based stage of AKI is considered when deciding to start or delay RRT. However, creatinine is not only determined by renal function (excretion), but also by dilution (fluid balance) and creatinine generation (muscle mass). The aim of this study was to explore whether fluid balance-adjusted creatinine at initiation of RRT is related to 28-day mortality independent of other markers of AKI, surrogates of muscle mass and severity of disease. METHODS: We performed a post-hoc analysis on data from the multicentre CASH trial comparing citrate to heparin anticoagulation during continuous venovenous hemofiltration (CVVH). To determine whether fluid balance-adjusted creatinine was associated with 28-day mortality, we performed a logistic regression analysis adjusting for confounders of creatinine generation (age, gender, body weight), other markers of AKI (creatinine, urine output) and severity of disease. RESULTS: Of the 139 patients, 32 patients were excluded. Of the 107 included patients, 36 died at 28 days (34%). Non-survivors were older, had higher APACHE II and inclusion SOFA scores, lower pH and bicarbonate, lower creatinine and fluid balance-adjusted creatinine at CVVH initiation. In multivariate analysis lower fluid balance-adjusted creatinine (OR 0.996, 95% CI 0.993-0.999, p = 0.019), but not unadjusted creatinine, remained associated with 28-day mortality together with bicarbonate (OR 0.869, 95% CI 0.769-0.982, P = 0.024), while the APACHE II score non-significantly contributed to the model. CONCLUSION: In this post-hoc analysis of a multicentre trial, low fluid balance-adjusted creatinine at CVVH initiation was associated with 28-day mortality, independent of other markers of AKI, organ failure, and surrogates of muscle mass, while unadjusted creatinine was not. More tools are needed for better understanding of the complex determinants of "AKI classification", "CVVH initiation" and their relation with mortality, fluid balance is only one.

ABSTRACT

BACKGROUND AND OBJECTIVES: Acute kidney injury (AKI) necessitating renal replacement therapy (RRT) is associated with high mortality and increased risk for end stage renal disease. However, it is unknown if this applies to patients with a preliminary unremarkable medical history. The purpose of this study was to describe overall and renal survival in critically ill patients with AKI necessitating RRT stratified by the presence of comorbidity. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS: A retrospective cohort study was performed, between 1994 and 2010, including all adult critically ill patients with AKI necessitating RRT, stratified by the presence of comorbidity. Logistic regression, survival curve and cox proportional hazards analyses were used to evaluate overall and renal survival. Standardized mortality rate (SMR) analysis was performed to compare long-term survival to the predicted survival in the Dutch population. RESULTS: Of the 1067 patients included only 96(9.0%) had no comorbidity. Hospital mortality was 56.6% versus 43.8% in patients with and without comorbidity, respectively. In those who survived hospitalization 10-year survival was 45.0% and 86.0%, respectively. Adjusted for age, sex and year of treatment, absence of comorbidity was not associated with hospital mortality (OR=0.74, 95%-CI=0.47-1.15), while absence of comorbidity was associated with better long-term survival (adjusted HR=0.28, 95%-CI = 0.14-0.58). Compared to the Dutch population, patients without comorbidity had a similar mortality risk (SMR=1.6, 95%-CI=0.7-3.2), while this was increased in patients with comorbidity (SMR=4.8, 95%-CI=4.1-5.5). Regarding chronic dialysis dependency, 10-year renal survival rates were 76.0% and 92.9% in patients with and without comorbidity, respectively. Absence of comorbidity was associated with better renal survival (adjusted HR=0.24, 95%-CI=0.07-0.76). CONCLUSIONS: While hospital mortality remains excessively high, the absence of comorbidity in critically ill patients with RRT-requiring AKI is associated with a relative good long-term prognosis in those who survive hospitalization.

ABSTRACT

BACKGROUND AND OBJECTIVES: Critically ill patients with AKI necessitating renal replacement therapy (RRT) have high in-hospital mortality, and survivors are at risk for kidney dysfunction at hospital discharge. The objective was to evaluate the association between impaired kidney function at hospital discharge with long-term renal and overall survival. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Degree of kidney dysfunction in relation to long-term effects on renal survival and patient mortality was investigated in a retrospective cohort study of 1220 adults admitted to an intensive care unit who received continuous RRT between 1994 and 2010. RESULTS: After hospital discharge, median follow-up of survivors (n=475) was 8.5 years (range, 1-17 years); overall mortality rate was 75%. Only 170 (35%) patients were discharged with an estimated GFR (eGFR) >60 ml/min per 1.73 m(2). Multivariate proportional hazards regression analysis demonstrated that age, nonsurgical type of admission, preexisting kidney disease, malignancy, and eGFR of 29-15 ml/min per 1.73 m(2) (hazard ratio [HR], 1.62; 95% confidence interval [CI], 1.01 to 2.58) and eGFR <15 ml/min per 1.73 m(2) (HR, 1.93; 95% CI, 1.23 to 3.02) at discharge were independent predictors of increased mortality. Renal survival was significantly associated with degree of kidney dysfunction at discharge. An eGFR of 29-15 ml/min per 1.73 m(2) (HR, 26.26; 95% CI, 5.59 to 123.40) and <15 ml/min per 1.73 m(2) (HR, 172.28; 95% CI, 37.72 to 786.75) were independent risk factors for initiation of long-term RRT. CONCLUSIONS: Most critically ill patients surviving AKI necessitating RRT have impaired kidney function at hospital discharge. An eGFR <30 ml/min per 1.73 m(2) is a strong risk factor for decreased long-term survival and poor renal survival.

ABSTRACT

PURPOSE: Identification of risk factors for impaired renal function at hospital discharge in critically ill patients with acute kidney injury (AKI) requiring renal replacement therapy (RRT). METHODS: A single-center retrospective cohort study was performed evaluating demographic and clinical parameters as potential risk factors for a modest to severely impaired renal function at hospital discharge in patients with AKI requiring RRT in the intensive care unit. RESULTS: Of the 353 patients in our cohort, 90 (25.5%) patients had pre-existing chronic kidney disease (CKD). An estimated glomerular filtration rate (eGFR) ≤60 mL min(-1) 1.73 m(-2) at hospital discharge occurred in 64.0% of which 63.7% without known renal impairment before hospital admission and 8.2% of all cases left the hospital dialysis-dependent. Multivariable logistic regression showed that age (OR = 1.051, P < .001), serum creatinine concentration at start of RRT (OR = 1.004, P < .001) and administration of iodine-containing contrast fluid (OR = 0.830, P = .045) were associated with an eGFR ≤60 mL min(-1) 1.73 m(-2). Furthermore, a medical history of CKD (OR = 5.865, P < .001) was associated with dialysis dependence. CONCLUSIONS: Elderly and patients with pre-existing CKD are at a high risk for modest to severely impaired renal function at hospital discharge after AKI requiring RRT.

ABSTRACT

Since impaired gallbladder emptying contributes to gallstone formation, the evaluation of gallbladder motility requires accurate methodology. Recently developed 3-dimensional ultrasonography may take into account various gallbladder shapes more accurately than conventional 2-dimensional ultrasonography. Therefore, volumes of water-filled balloons of various sizes were determined in vitro by 2-dimensional ultrasonography with the sum of cylinders method and by 3-dimensional ultrasonography. Also, in 15 gallstone patients and 6 healthy volunteers, fasting gallbladder volumes and postprandial motility were determined by both methods. Volumes of water-filled balloons as measured by both methods correlated strongly with true volumes (R= 0.93 for 2-dimensional and R = 0.98 for 3- dimensional ultrasonography). Gallbladder volumes measured by both methods were also correlated (R = 0.66, P <0.001). In gallstone patients, 3-dimensional ultrasonography yielded smaller gallbladder volumes than 2-dimensional ultrasonography (P = 0.007), but not in healthy subjects. With both methods, gallstone patients exhibited decreased postprandial gallbladder motility compared to healthy subjects. In conclusion, gallbladder volume measurements by 3-dimensional and 2-dimensional ultrasonography are strongly correlated.Nevertheless, in gallstone patients, gallbladder volumes by 3-dimensional ultrasonography tend to be smaller than by 2-dimensional ultrasonography, possibly due to interference of gallstones with the volume measurement.

ABSTRACT

OBJECTIVES: Pancreatitis is a severe complication of gallstone disease with considerable mortality. Small gallstones may increase the risk of pancreatitis. Our aims were to evaluate potential association of small stones with pancreatitis and potential beneficial effects of prophylactic cholecystectomy. METHODS: Stone characteristics were determined in patients with biliary pancreatitis (115), obstructive jaundice due to gallstones (103), acute cholecystitis (79), or uncomplicated gallstone disease (231). Sizes and numbers of gallbladder and bile duct stones were determined by ultrasonography and endoscopic retrograde cholangiopancreatography, respectively. Effects of prophylactic cholecystectomy were assessed by decision analyses with a Markov model and Monte Carlo simulations. RESULTS: Patients with pancreatitis or obstructive jaundice had more and smaller gallbladder stones than those with acute cholecystitis or uncomplicated disease (diameters of smallest stones: 3 +/- 1, 4 +/- 1, 8 +/- 1, and 9 +/- 1 mm, respectively, p < 0.01). Bile duct stones were smaller in case of pancreatitis than in obstructive jaundice (diameters of smallest stones: 4 +/- 1 vs 8 +/- 1, p < 0.01). Multivariate analysis identified old age and small stones as independent risk factors for pancreatitis. Decision analysis in a representative group of patients with small (
