Prevalence of acute kidney injury in myeloma patients visiting U.S. emergency departments: A nationwide analysis.

e20548 Background: Patients diagnosed with multiple myeloma (MM) frequently visit emergency departments (ED) with complications, commonly with kidney disease. However, data regarding the prevalence of acute kidney injury (AKI) and its effects on patient outcome, economic burden, length of hospital stay and mortality among these patients are lacking. Methods: From the Nationwide Emergency Department Sample, we obtained 7-year (2010-2016) data of myeloma patients who visited ED. Baseline characteristics of these patients with and without AKI were compared. The multivariable regression model was used to estimate hospital admission, length of stay, healthcare burden and in-hospital mortality in patients with and without AKI. Results: Between 2010-2016, 657,392 adult myeloma patients visited ED at an increased rate from 35 to 45 per 100,000 census population. The prevalence of AKI was 22.5% (n = 147,743) with a stable trend over the study period. AKI was more common in patients with relapsed MM (33.5%) than those in remission (18.6%) or never achieving remission (22.4%) (P < 0.001), male (24.1 vs 20.6% in female, P < 0.001), age ≥65 years (24.1%) vs 18-44 years (12.9%), or 45-64 years (19.3%)(P < 0.001) and urban (23.3%) vs non-urban residents (17.9%)(P < 0.001). The majority patients with AKI were hospitalized (96.5%) compared with those without AKI (69.6%) (P < 0.001). In multivariable analysis, odds of hospitalization was higher in patients with AKI (OR: 8.8, P < 0.001) after adjusting age, gender, co-morbidities and other demographics. Median hospital stay was longer in patients with AKI compared to those without (6 vs 4 days, P < 0.001). Median ED and total hospitalization charges were higher in patients with AKI (ED: $2,057; total: $45,414) vs without AKI (ED: $1,853; total: $29,299) (P < 0.001). In the multivariable adjusted-model, odds of in-hospital mortality was significantly higher in patients not in remission (OR: 1.8), patients with relapse (OR: 2.3), AKI (OR: 2.2), age ≥ 65 years (OR: 1.4), male (OR: 1.1) and urban residents (OR:1.2). Conclusions: In this largest national study of MM patients visiting ED, patients with AKI had higher in-hospital admission, ED and total charges, length of hospital stays, and mortality, both by univariate and multivariate analysis. Prevalence of AKI and mortality were highest in patients with MM relapse.

Abstract Introduction The effect of valve type on outcomes in transfemoral transcatheter aortic valve replacement (TF-TAVR) has recently been subject of debate. We investigate outcomes of patients treated with balloon-expanding (BE) vs. self-expanding (SE) valves in in a cohort of all these procedures performed in Germany in 2018. Methods All patients receiving TF-TAVR with either BE (N = 9,882) or SE (N = 7,413) valves in Germany in 2018 were identified. In-hospital outcomes were analyzed for the endpoints in-hospital mortality, major bleeding, stroke, acute kidney injury, postoperative delirium, permanent pacemaker implantation, mechanical ventilation > 48 h, length of hospital stay, and reimbursement. Since patients were not randomized to the two treatment options, logistic or linear regression models were used with 22 baseline patient characteristics and center-specific variables as potential confounders. As a sensitivity analysis, the same confounding factors were taken into account using the propensity score methods (inverse probability of treatment weighting). Results Baseline characteristics differed substantially, with higher EuroSCORE (p < 0.001), age (p < 0.001) and rate of female sex (p < 0.001) in SE treated patients. After risk adjustment, no marked differences in outcomes were found for in-hospital mortality [risk adjusted odds ratio (aOR) for SE instead of BE 0.94 (96% CI 0.76;1.17), p = 0.617] major bleeding [aOR 0.91 (0.73;1.14), p = 0.400], stroke [aOR 1.13 (0.88;1.46), p = 0.347], acute kidney injury [OR 0.97 (0.85;1.10), p = 0.621], postoperative delirium [aOR 1.09 (0.96;1.24), p = 0.184], mechanical ventilation > 48 h [aOR 0.98 (0.77;1.25), p = 0.893], length of hospital stay (risk adjusted difference in days of hospitalization (SE instead of BE): − 0.05 [− 0.34;0.25], p = 0.762) and reimbursement [risk adjusted difference in reimbursement (SE instead of BE): − €72 (− €291;€147), p = 0.519)] There is, however, an increased risk of PPI for SE valves (aOR 1.27 [1.15;1.41], p < 0.001). Similar results were found after application of propensity score adjustment. Conclusions We find broadly equivalent outcomes in contemporary TF-TAVR procedures, regardless of the valve type used. Incidence of major complications is very low for both types of valve.

AbstractAcute kidney injury (AKI) is a major global public health problem. It is expensive to manage and associated with a high rate of prolonged hospitalization and in-hospital mortality. Little is known about the burden of acute kidney injury in moderate to low-income countries. We aim to assess predictors of in-hospital mortality among AKI patients admitted to the medical ward. We prospectively identified patients meeting kidney disease improving global outcomes (KIDGO) AKI definitions from April to August 2019. Patients with underlying CKD and patients hospitalized for less than 48 h were excluded. The Cox regression model was fitted to identify predictors of mortality and statistical significance was considered at the p-value of less than 0.05. A total of 203 patients were enrolled over 5 months. Out of this, 121(59.6%) were males, 58(28.6%) were aged greater than 60 years, and 141(69.5%) had community-acquired acute kidney injury. The most common causes of AKI were Hypovolemia 99(48.77%), Glomerulonephritis 51(25.11%), and sepsis 32(15.79%). The overall in-hospital mortality rate was 12.8%. Stage 3 AKI (AHR = 9.61, 95% CI 1.17–28.52, p = 0.035), duration of AKI (AHR = 7.04, 95% CI 1.37–36.08, p = 0.019), length of hospital stay (AHR = 0.19, 95% CI 0.05–0.73, p = 0.012), and hyperkalemia (AHR = 3.61, 95% CI 1.12–11.71, p = 0.032) were significantly associated with in-hospital mortality. There is a high rate of acute kidney injury-related in-hospital mortality in adult patients admitted to the medical ward. The severity of AKI, hyperkalemia duration of AKI, and a short length of hospital stay were predictors of 30-days in-hospital mortality. Most of the causes of AKI are preventable and patients may benefit from early identification and treatment of these reversible causes.

Outcome Parameters

Objectives: Extracorporeal cardiopulmonary resuscitation (eCPR) is increasingly used due to its beneficial outcomes and results compared with conventional CPR. Data after eCPR for acute kidney injury (AKI) are lacking. We sought to investigate factors predicting AKI in patients who underwent eCPR. Methods: From January 2016 until December 2020, patients who underwent eCPR at our institution were retrospectively analyzed and divided into two groups: patients who developed AKI ( n = 60) and patients who did not develop AKI ( n = 35) and analyzed for outcome parameters. Results: Overall, 63% of patients suffered AKI after eCPR and 45% of patients who developed AKI needed subsequent dialysis. Patients who developed AKI showed higher values of creatinine (1.1 mg/dL vs 1.5 mg/dL, p ⩽ 0.01), urea (34 mg/dL vs 42 mg/dL, p = 0.04), CK (creatine kinase) (923 U/L vs 1707 U/L, p = 0.07) on admission, and CK after 24 hours of ECMO support (1705 U/L vs 4430 U/L, p = 0.01). ECMO explantation was significantly more often performed in patients who suffered AKI (24% vs 48%, p = 0.01). In-hospital mortality (86% vs 70%; p = 0.07) did not differ significantly. Conclusion: Patients after eCPR are at high risk for AKI, comparable to those after conventional CPR. Baseline urea levels predict the development of AKI during the hospital stay.

ObjectiveThe purpose of this study was to perform a systematic review and meta-analysis to evaluate the effect of high-dose versus low-dose haemofiltration on the survival of critically ill patients with acute kidney injury (AKI). We hypothesised that high-dose treatments are not associated with a higher risk of mortality.DesignMeta-analysis.SettingRandomised controlled trials and two-arm prospective and retrospective studies were included.ParticipantsCritically ill patients with AKI.InterventionsContinuous renal replacement therapy.Primary and secondary outcome measuresPrimary outcomes: 90-day mortality, intensive care unit (ICU) mortality, hospital mortality; secondary outcomes: length of ICU and hospital stay.ResultEight studies including 2970 patients were included in the analysis. Pooled results showed no significant difference in the 90-mortality rate between patients treated with high-dose or low-dose haemofiltration (pooled OR=0.90, 95% CI 0.73 to 1.11, p=0.32). Findings were similar for ICU (pooled OR=1.12, 95% CI 0.94 to 1.34, p=0.21) and hospital mortality (pooled OR=1.03, 95% CI 0.81 to 1.30, p=0.84). Length of ICU and hospital stay were similar between high-dose and low-dose groups. Pooled results are not overly influenced by any one study, different cut-off points of prescribed dose or different cut-off points of delivered dose. Meta-regression analysis indicated that the results were not affected by the percentage of patients with sepsis or septic shock.ConclusionHigh-dose and low-dose haemofiltration produce similar outcomes with respect to mortality and length of ICU and hospital stay in critically ill patients with AKI.This study was not registered at the time the data were collected and analysed.

Abstract Background : With the increasing worldwide prevalence and disease burden of diabetic mellitus, data on the impact of diabetes on acute kidney injury (AKI) patients in China are limited.Methods: A nationwide cross-sectional and retrospective study was conducted in China, which included 2,223,230 hospitalized adult patients and covered 82% of the country’s population. Diabetes was identified according to blood glucose, hemoglobin A1c levels, physician diagnosis and drug use. In total, 7604 AKI patients were identified, and 1404 and 6200 cases were defined as diabetic and non-diabetic respectively. Clinical characteristics, outcome, in-hospital stay, and costs of AKI patients with and without diabetes were compared. Multivariable logistic and linear regression analyses were conducted to evaluate the association of diabetes with mortality and renal recovery in the admitted AKI patients.Results: In this survey, AKI patients with diabetes were older, male-dominated (61.9%), with more comorbidities, and higher serum creatinine levels. Compared to patients without diabetes, a significant upswing in all-cause in-hospital mortality, hospital stay, and costs were found in those with diabetes ( p <0.05). After adjusted for relevant covariables, diabetes was independently associated with failed renal recovery (OR=1.13, p =0.04), rather than all-cause in-hospital mortality (OR=1.09, p =0.39). Also, diabetic status was positively associated with length of stay ( β =0.04, p =0.04) and costs ( β =0.09, p <0.01) in hospital after adjusted for possible confounders. Conclusions: Failed renal recovery, rather than all-cause in-hospital mortality, is independently associated with diabetes in hospitalized AKI patients. Moreover, diabetes is significantly correlated with in-hospital stay and expenditures in AKI.

Abstract Introduction: Acute kidney injury (AKI) has been described in Coronavirus Disease 2019 (COVID-19) patients and is considered a marker of disease severity and a negative prognostic factor for survival. In this study, the authors aimed to study the impact of transient and persistent acute kidney injury (pAKI) on in-hospital mortality in COVID-19 patients. Methods: This was a retrospective observational study of patients hospitalized with COVID-19 in the Department of Medicine of the Centro Hospitalar Universitario Lisboa Norte, Lisbon, Portugal, between March 2020 and August 2020. A multivariate analysis was performed to predict AKI development and in-hospital mortality. Results: Of 544 patients with COVID-19, 330 developed AKI: 166 persistent AKI (pAKI), 164 with transient AKI. AKI patients were older, had more previous comorbidities, had higher need to be medicated with RAAS inhibitors, had higher baseline serum creatine (SCr) (1.60 mg/dL vs 0.87 mg/dL), higher NL ratio, and more severe acidemia on hospital admission, and more frequently required admission in intensive care unit, mechanical ventilation, and vasopressor use. Patients with persistent AKI had higher SCr level (1.71 mg/dL vs 1.25 mg/dL) on hospital admission. In-hospital mortality was 14.0% and it was higher in AKI patients (18.5% vs 7.0%). CKD and serum ferritin were independent predictors of AKI. AKI did not predict mortality, but pAKI was an independent predictor of mortality, as was age and lactate level. Conclusion: pAKI was independently associated with in-hospital mortality in COVID-19 patients but its impact on long-term follow-up remains to be determined.

Introduction. Detecting acute kidney injury (AKI) in the first days of hospitalization could prevent potentially fatal complications. However, epidemiological data are scarce, especially on nonsurgical patients.Objectives. To determine the incidence and risk factors associated with AKI within five days of hospitalization (EAKI).Methods. Prospective cohort of patients hospitalized in the Internal Medicine Department.Results. A total of 16% of 400 patients developed EAKI. The associated risk factors were prehospital treatment with nephrotoxic drugs (2.21 OR; 95% CI 1.12–4.36,p=0.022), chronic kidney disease (CKD) in stages 3 to 5 (3.56 OR; 95% CI 1.55–8.18,p<0.003), and venous thromboembolism (VTE) at admission (5.05 OR; 95% CI 1.59–16.0,p<0.006). The median length of hospital stay was higher among patients who developed EAKI (8 [IQR 5–14] versus 6 [IQR 4–10],p=0.008) and was associated with an increased requirement for dialysis (4.87 OR 95% CI 2.54 to 8.97,p<0.001) and in-hospital death (3.45 OR; 95% CI 2.18 to 5.48,p<0.001).Conclusions. The incidence of EAKI in nonsurgical patients is similar to the worldwide incidence of AKI. The risk factors included CKD from stage 3 onwards, prehospital treatment with nephrotoxic drugs, and VTE at admission. EAKI is associated with prolonged hospital stay, increased mortality rate, and dialysis requirement.

Abstract Background Early detection and prevention of acute kidney injury (AKI) is important to reduce morbidity and mortality. Discovery of early-detection biomarkers has enabled early preventive approaches. There are no data on early biomarker-guided intervention with nephrological consultation in emergency departments (EDs). Methods In this prospective randomized controlled intervention trial, patients at high risk for AKI were screened with urinary [TIMP-2]·[IGFBP7] in the ED of Robert-Bosch-Hospital (Stuttgart, Germany). We screened 257 eligible patients of whom 100 met the inclusion criteria, with urinary [TIMP-2]·[IGFBP7] >0.3, and were included. The intervention group received immediate one-time nephrological consultation after randomization, implementing Kidney Disease: Improving Global Outcomes (KDIGO) 2012 recommendations on AKI. The primary outcome was the incidence of moderate to severe AKI within the first day after admission. Secondary outcomes were AKI occurrence within 3 days after admission, need for renal replacement therapy (RRT), length of hospital stay and death. Results The primary outcome did not differ significantly (P = 0.9) between the groups, neither within the first day nor within the first 3 days after admission. The intervention group had significantly (P < 0.05) lower serum creatinine (SCr) on Day 2 and lower maximum SCr and tended (P = 0.08) to have higher urine output (UOP) at Day 3 than the non-intervention group. No patient in the intervention group needed RRT (0 versus 3) during the hospital stay (P = 0.09). Conclusions One-time routine nephrologist-guided application of the KDIGO bundle in ED patients with a risk for AKI cannot currently be recommended. However, due to the uniform trend of study endpoints in favour of intervention, further trials to investigate larger cohorts of more severely ill patients are warranted.

Background: Post-procedural acute kidney injury (AKI) is associated with significantly increased short- and long-term mortalities, and renal loss. Few studies have compared the incidence of post-procedural AKI and in-hospital mortality between 2 major modalities of revascularization - coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) - and results have been inconsistent. Methods: We generated a propensity score-matched cohort that includes a total of 286,670 hospitalizations with multi-vessel coronary disease undergoing CABG or PCI (2004-2012) from the National Inpatient Sample database. We compared incidence of AKI, AKI requiring renal replacement therapy (RRT), in-hospital mortality, hospital stay, and charges between CABG and PCI groups. Results: The incidence of AKI after CABG was higher than PCI (8.9 vs. 4.5%, OR 2.05, 95% CI 1.99-2.12, p < 0.001). The incidence of AKI requiring RRT was also higher after CABG (1.1 vs. 0.5%, OR 2.14, 95% CI 1.96-2.34, p < 0.001). Likewise, in-hospital mortality was higher after CABG than PCI (2.0 vs. 1.4%, OR 1.44, 95% CI 1.35-1.52, p < 0.001). Among patients with pre-existing chronic kidney disease (stages I-IV), those undergoing CABG was associated with 2.0-2.3-fold higher odds of developing AKI than those undergoing PCI. The patients treated with CABG had a significantly longer hospital stay and higher hospital charges. Conclusions: Patients undergoing CABG are associated with (1) increased risk of developing post-procedural AKI, (2) higher likelihood of receiving RRT, and (3) worse short-term survival. Long-term renal outcome remains to be studied.
