Am J Kidney Dis 2024; 84:145-153.e1. [PMID: 38490319 DOI: 10.1053/j.ajkd.2024.01.526] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Revised: 01/07/2024] [Accepted: 01/20/2024] [Indexed: 03/17/2024]
Abstract
RATIONALE & OBJECTIVE Continuous kidney replacement therapy (CKRT) is preferred when available for hemodynamically unstable acute kidney injury (AKI) patients in the intensive care unit (ICU). The Kidney Disease: Improving Global Outcomes (KDIGO) guidelines recommend a delivered CKRT dose of 20-25mL/kg/h; however, in Japan the doses are typically below this recommendation due to government health insurance system restrictions. This study investigated the association between mortality and dose of CKRT. STUDY DESIGN Single-center retrospective cohort study. SETTING & PARTICIPANTS Critically ill patients with AKI treated with CKRT at a tertiary Japanese university hospital between January 1, 2012, and December 31, 2021. EXPOSURE Delivered CKRT doses below or above the median. OUTCOME 90-day mortality after CKRT initiation. ANALYTICAL APPROACH Multivariable Cox regression analysis and Kaplan-Meier analysis. RESULTS The study population consisted of 494 patients. The median age was 72 years, and 309 patients (62.6%) were men. Acute tubular injury was the leading cause of AKI, accounting for 81.8%. The median delivered CKRT dose was 13.2mL/kg/h. Among the study participants, 456 (92.3%) received delivered CKRT doses below 20mL/kg/h, and 204 (41.3%) died within 90 days after CKRT initiation. Multivariable Cox regression analysis revealed increased mortality in the below-median group (HR, 1.73 [95% CI, 1.19-2.51], P=0.004). Additionally, a significant, inverse, nonlinear association between 90-day mortality and delivered CKRT dose was observed using delivered CKRT dose as a continuous variable. LIMITATIONS Single-center, retrospective, observational study. CONCLUSIONS A lower delivered CKRT dose was independently associated with higher 90-day mortality among critically ill patients who mostly received dosing below the current KDIGO recommendations. PLAIN-LANGUAGE SUMMARY The Kidney Disease: Improving Global Outcomes (KDIGO) guidelines recommend delivering a continuous kidney replacement therapy (CKRT) dose of 20-25mL/kg/h. However, it is not clear if it is safe to use delivered CKRT doses below this recommendation. In this study, over 90% of the patients received CKRT with a delivered dose below the KDIGO recommendation. We divided these patients into 2 groups based on the median delivered CKRT dose. Our findings show that a delivered CKRT dose below the median was associated with increased risk of death within 90 days. These findings show that a lower delivered CKRT dose was independently associated with higher 90-day mortality among critically ill patients who mostly received dosing below current KDIGO recommendations.

Abstract
Rationale & Objective Continuous kidney replacement therapy (CKRT) is the predominant form of acute kidney replacement therapy used for critically ill adult patients with acute kidney injury (AKI). Given the variability in CKRT practice, a contemporary understanding of its epidemiology is necessary to improve care delivery. Study Design Multicenter, prospective living registry. Setting & Population 1,106 critically ill adults with AKI requiring CKRT from December 2013 to January 2021 across 5 academic centers and 6 intensive care units. Patients with pre-existing kidney failure and those with coronavirus 2 infection were excluded. Exposure CKRT for more than 24 hours. Outcomes Hospital mortality, kidney recovery, and health care resource utilization. Analytical Approach Data were collected according to preselected timepoints at intensive care unit admission and CKRT initiation and analyzed descriptively. Results Patients' characteristics, contributors to AKI, and CKRT indications differed among centers. Mean (standard deviation) age was 59.3 (13.9) years, 39.7% of patients were women, and median [IQR] APACHE-II (acute physiologic assessment and chronic health evaluation) score was 30 [25-34]. Overall, 41.1% of patients survived to hospital discharge. Patients that died were older (mean age 61 vs. 56.8, P < 0.001), had greater comorbidity (median Charlson score 3 [1-4] vs. 2 [1-3], P < 0.001), and higher acuity of illness (median APACHE-II score 30 [25-35] vs. 29 [24-33], P = 0.003). The most common condition predisposing to AKI was sepsis (42.6%), and the most common CKRT indications were oliguria/anuria (56.2%) and fluid overload (53.9%). Standardized mortality ratios were similar among centers. Limitations The generalizability of these results to CKRT practices in nonacademic centers or low-and middle-income countries is limited. Conclusions In this registry, sepsis was the major contributor to AKI and fluid management was collectively the most common CKRT indication. Significant heterogeneity in patient- and CKRT-specific characteristics was found in current practice. These data highlight the need for establishing benchmarks of CKRT delivery, performance, and patient outcomes. Data from this registry could assist with the design of such studies.

Abstract
PURPOSE OF REVIEW Quality and safety are important themes in acute kidney care (AKC). There have been many recent initiatives highlighting these aspects. However, for these to become part of clinical practice, a rigorous implementation science methodology must be followed. This review will present these practices and will highlight recent initiatives in acute kidney injury (AKI), kidney replacement therapy (KRT) and recovery from AKI. RECENT FINDINGS The 22nd Acute Disease Quality Initiative (ADQI) focused on achieving a framework for improving AKI care. This has led to various quality improvement (QI) initiatives that have been implemented following a robust implementation science methodology. In AKI, QI initiatives have been focused on implementing care bundles and early detection systems for patients at risk or with AKI. KRT initiatives have focused on measuring and reporting key performance indicators (KPIs), and providing targeted feedback and education to improve delivery of KRT. Finally, it has been recognized that post-AKI care is vitally important, and ongoing work has been focused on implementing pathways to ensure continuing kidney-focused care. SUMMARY Quality and safety continue to be important focuses in AKC. Although recent work have focused on initiatives to improve these themes, additional work is necessary to further develop these items as we strive to improve the care to patients with AKI.

Abstract
Abstract
Background
Acute kidney replacement therapy (KRT) is delivered to acutely ill patients to support organ function and life in the Intensive Care Unit (ICU). Implementing standardized acute KRT pathways can ensure its safe and effective management. At present, there is no standardized approach to the management of acute KRT in Alberta ICUs.
Methods
Dialyzing Wisely is a registry embedded, stepped-wedge, interrupted time-series evaluation of the implementation of a standardized, stakeholder-informed, and evidence-based acute KRT pathway into Alberta ICUs. The acute KRT pathway will consist of two distinct phases. First, we will implement routine monitoring of evidence-informed key performance indicators (KPIs) of acute KRT. Second, we will provide prescriber and program reports for acute KRT initiation patterns. After the implementation of both phases of the pathway, we will evaluate acute KRT performance quarterly and implement a customized suite of interventions aimed at improving performance. We will compare this with baseline and evaluate iterative post implementation effects of the care pathway.
Discussion
Dialyzing Wisely will implement, monitor, and report a suite of KPIs of acute KRT, coupled with a care pathway that will transform the quality of acute KRT across ICUs in Alberta. This program will provide a framework for scaling evidence-informed approaches to monitoring and management of acute KRT in other jurisdictions. We anticipate improvements in acute KRT performance, decreased healthcare system costs and improved patient quality of life by decreasing patient dependence on maintenance dialysis.

Research on the Application Effect of Strengthening Risk Management in Continuous Renal Replacement Therapy Nursing of Critically Ill Patients. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:2363877. [PMID: 35845585 PMCID: PMC9286961 DOI: 10.1155/2022/2363877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 05/21/2022] [Accepted: 06/17/2022] [Indexed: 11/24/2022]
Abstract
Objective To evaluate the efficacy of risk management in the nursing of critically ill patients on continuous renal replacement therapy (CRRT). Methods In this retrospective study, 80 critically ill patients on continuous renal replacement therapy in our hospital from February 2020 to February 2021 were recruited. They were randomly assigned to receive either the risk management treatment (risk management group) or the conventional management treatment (conventional management group) via the random number table method. Outcome measurements included the occurrence of adverse events, complications, psychological status, quality of life, treatment compliance, duration of CRRT, and nursing satisfaction. Results Risk management treatment was associated with lower incidence of adverse events compared to conventional management treatment (P value < 0.05). The risk management group also resulted in a lower incidence of complications compared to the conventional management group (P value < 0.05). Patients who received risk management treatments demonstrated a significantly lower anxiety/depression level and a higher World Health Organization Quality of Life Brief Version (WHOQOL-BREF) (P value < 0.05). The risk management group resulted in more cases with high compliance and fewer cases with moderate and poor compliance (P < 0.05). Risk management was associated with more cases with a CRRT duration less than 36 hours and 36–48 hours and fewer cases with a duration longer than 48 h (X2 = 2.999, P value < 0.05). Patients who were given a risk management treatment had a higher nursing satisfaction compared to conventional management treatment (X2 = 4.501, P value < 0.05). Conclusion Risk management treatment in caring of critically ill patients on CRRT shows better efficacy than conventional management treatments.

Abstract
INTRODUCTION Continuous renal replacement therapy (CRRT) is a continuous form of dialysis used to support critically ill patients with acute kidney injury. The ideal delivery of CRRT requires ongoing monitoring and reporting to adjust practice and deliver optimal therapy. However, this practice occurs variably. METHODS QUALITY CRRT is a multicentre, prospective, stepped-wedged, interrupted time series (ITS) evaluation of the effectiveness, safety and cost of implementing a multifaceted CRRT quality assurance and improvement programme across an entire healthcare system. This study will focus on the standardisation of CRRT programmes with similar structure, process and outcome metrics by the reporting of CRRT key performance indicators (KPIs). The primary outcome will be the quarterly performance of CRRT KPIs. Secondary outcomes will include patient-centred outcomes and economic outcomes. Analysis will compare pre-implementation and post-implementation groups as well as for the performance of KPIs using an ITS methodology. The health economic evaluation will include a within-study analysis and a longer-term model-based analysis. DISCUSSION The effective delivery of CRRT to critically ill patients ideally requires a standardised approach of best practice assessment and ongoing audit and feedback of standardised performance measures. QUALITY CRRT will test the application of this strategy stakeholder engagement and stepped-wedged implementation across an entire healthcare system. ETHICS AND DISSEMINATION This study has received ethics approval. We will plan to publish the results in a peer-reviewed journal. TRIAL REGISTRATION NUMBER NCT04221932. PROTOCOL VERSION 1.0 (15 June 2020).

Abstract
BACKGROUND Continuous renal replacement therapy (CRRT) is a lifesaving intervention for critically ill patients. Delays in initiation, or an inability to resume CRRT following a temporary suspension in therapy (CRRT restart), can result in suboptimal CRRT delivery. LOCAL PROBLEM Intensive care units across the health care system were experiencing significant delays in CRRT initiation and restarts. APPROACH A multimodal quality improvement initiative was implemented across 7 adult intensive care units, which allowed unit-based staff nurses to initiate and restart CRRT, a task that had previously been delegated to non-unit-based dialysis nurses. OUTCOMES A 75% reduction in CRRT initiation delays and a 90% reduction in CRRT restart delays were observed in the 12 months following the initiative. There were no adverse events or increased disposable CRRT circuit usage following the initiative. CONCLUSIONS Implementation of CRRT initiation and restarts by unit-based nurses were achievable and resulted in substantial improvements in timeliness of CRRT delivery.

Abstract
Continuous renal replacement therapy (CRRT) downtime is considered a quality indicator; however, it remains uncertain whether downtime affects outcomes. This study retrospectively investigated the impact of downtime on clinical outcomes. Patients were classified as downtime <20% or ≥20% of potential operative time over 4 days from CRRT initiation. Patients with ≥20% downtime were matched to those with <20% downtime using 1:2 propensity score matching. There were 88 patients with <20% downtime and 44 patients with ≥20% downtime. The cumulative effluent volume was lower in patients with ≥20% downtime (p < 0.001). The difference in levels of urea and creatinine widened over time (p = 0.004 and <0.001). At days 2 and 3, daily fluid balance differed (p = 0.046 and 0.031), and the levels of total carbon dioxide were lower in those with ≥20% downtime (p = 0.038 and 0.020). Based on our results, ≥20% downtime was not associated with increased 28 day mortality; however, a subgroup analysis showed the interaction between downtime and daily fluid balance (p = 0.004). In conclusion, increased downtime could impair fluid and uremic control and acidosis management. Moreover, the adverse effect of downtime on fluid control may increase mortality rate. Further studies are needed to verify the value of downtime in critically ill patients requiring CRRT.

Abstract
OBJECTIVES Thrombocytopenia is common in critically ill patients treated with continuous renal replacement therapy and decreases in platelets following continuous renal replacement therapy initiation have been associated with increased mortality. Platelets play a role in innate and adaptive immunity, making it plausible that decreases in platelets following continuous renal replacement therapy initiation predispose patients to development of infection. Our objective was to determine if greater decreases in platelets following continuous renal replacement therapy correlate with increased rates of secondary infection. DESIGN Retrospectivecohort analysis. SETTING This study uses a continuous renal replacement therapy database from Mayo Clinic (Rochester, MN), a tertiary academic center. PARTICIPANTS Adult patients who survived until ICU discharge and were on continuous renal replacement therapy for less than 30 days were included. A subgroup analysis was also performed in patients with thrombocytopenia (platelets < 100 × 103/µL) at continuous renal replacement therapy initiation. MEASUREMENTS AND MAIN RESULTS The primary predictor variable was a decrease in platelets from precontinuous renal replacement therapy levels of greater than 40% or less than or equal to 40%, although multiple cut points were analyzed. The primary outcome was infection after ICU discharge, and secondary endpoints included post-ICU septic shock and post-ICU mortality. Univariable, multivariable, and propensity-adjusted analyses were used to determine associations between the predictor variable and the outcomes. RESULTS Among 797 eligible patients, 253 had thrombocytopenia at continuous renal replacement therapy initiation. A greater than 40% decrease in platelets after continuous renal replacement therapy initiation was associated in the multivariable-adjusted models with increased odds of post-ICU infection in the full cohort (odds ratio, 1.49; CI, 1.02-2.16) and in the thrombocytopenia cohort (odds ratio, 2.63; CI, 1.35-5.15) cohorts. CONCLUSIONS Platelet count drop by greater than 40% following continuous renal replacement therapy initiation is associated with an increased risk of secondary infection, particularly in patients with thrombocytopenia at the time of continuous renal replacement therapy initiation. Further research is needed to evaluate the impact of both continuous renal replacement therapy and platelet loss on subsequent infection risk.

Abstract
Continuous renal replacement therapy (CRRT) is the preferred modality of extracorporeal renal support for critically ill patients with acute kidney injury (AKI). The dose of CRRT is reported as effluent flow in ml/kg body weight per hour (ml/kg/h). Solid evidence supports that the delivered CRRT effluent dose for critically ill patients with AKI should be 20-25 ml/kg/h on average. To account for treatment interruptions and the natural decline in filter efficiency over time, it is recommended to prescribe 25-30 ml/kg/h of effluent dose. However, transient higher doses of CRRT in specific clinical scenarios may be needed to accommodate specific solute control needs of a particular patient at a given time. Consequently, there should be consideration of the potential adverse consequences of non-selective clearance such as undesired antimicrobials and nutrients removal. In this manuscript, we provide a summary of evidence related to CRRT dose, practical aspects for its calculation at the time of prescribing CRRT, and considerations for addressing the expected gap between prescribed and delivered CRRT dose. We also provide a framework for monitoring and implementation of CRRT dose as a quality indicator of CRRT delivery.

Abstract
Continuous renal replacement therapy (CRRT) is the preferred extracorporeal kidney support therapy employed to support critically ill patients with acute or chronic kidney dysfunction in intensive care units. Significant heterogeneity in CRRT practice exists in part due to variable logistics, resources, and scarcity of evidence-based CRRT practices. Importantly, homogenization of practice patterns by developing substantial evidence and effective dissemination among providers is essential for optimizing CRRT practices. The emphasis on quality of CRRT delivery has prompted identification of potential quality indicators, development of multifaceted quality improvement initiatives, effective computer science utilization, and a surge of multidisciplinary quality assurance teams that advocate for "best" CRRT practices. This manuscript provides an overview of quality improvement methodologies and reviews candidate quality indicators of CRRT and the impact of quality improvement on enhancing CRRT delivery practices.

Abstract
Acute kidney injury (AKI) is common in critically ill patients, and renal replacement therapy (RRT) constitutes an important aspect of acute management during critical illness. Continuous RRT (CRRT) is frequently utilized in intensive care unit settings, particularly in patients with severe AKI, fluid overload, and hemodynamic instability. The main goal of CRRT is to timely optimize solute control, acid-base, and volume status. Total effluent dose of CRRT is a deliverable that depends on multiple factors and therefore should be systematically monitored (prescribed vs. delivered) and iteratively adjusted in a sustainable mode. In this manuscript, we review current evidence of CRRT dosing and provide recommendations for its implementation as a quality indicator of CRRT delivery.

Abstract
PURPOSE OF REVIEW This article reviews the current evidence supporting the use of precision medicine in the delivery of acute renal replacement therapy (RRT) to critically ill patients, focusing on timing, solute control, anticoagulation and technologic innovation. RECENT FINDINGS Precision medicine is most applicable to the timing of RRT in critically ill patients. As recent randomized controlled trials have failed to provide consensus on when to initiate acute RRT, the decision to start acute RRT should be based on individual patient clinical characteristics (e.g. severity of the disease, evolution of clinical parameters) and logistic considerations (e.g. organizational issues, availability of machines and disposables). The delivery of a dynamic dialytic dose is another application of precision medicine, as patients may require different and varying dialysis doses depending on individual patient factors and clinical course. Although regional citrate anticoagulation (RCA) is recommended as first-line anticoagulation for continuous RRT, modifications to RCA protocols and consideration of other anticoagulants should be individualized to the patient's clinical condition. Finally, the evolution of RRT technology has improved precision in dialysis delivery through increased machine accuracy, connectivity to the electronic medical record and automated reduction of downtime. SUMMARY RRT has become a complex treatment for critically ill patients, which allows for the prescription to be precisely tailored to the different clinical requirements.

Development, implementation and outcomes of a quality assurance system for the provision of continuous renal replacement therapy in the intensive care unit. Sci Rep 2020; 10:20616.

Abstract
Critically ill patients with requirement of continuous renal replacement therapy (CRRT) represent a growing intensive care unit (ICU) population. Optimal CRRT delivery demands continuous communication between stakeholders, iterative adjustment of therapy, and quality assurance systems. This Quality Improvement (QI) study reports the development, implementation and outcomes of a quality assurance system to support the provision of CRRT in the ICU. This study was carried out at the University of Kentucky Medical Center between September 2016 and June 2019. We implemented a quality assurance system using a step-wise approach based on the (a) assembly of a multidisciplinary team, (b) standardization of the CRRT protocol, (c) creation of electronic CRRT flowsheets, (d) selection, monitoring and reporting of quality metrics of CRRT deliverables, and (e) enhancement of education. We examined 34-month data comprising 1185 adult patients on CRRT (~ 7420 patient-days of CRRT) and tracked selected QI outcomes/metrics of CRRT delivery. As a result of the QI interventions, we increased the number of multidisciplinary experts in the CRRT team and ensured a continuum of education to health care professionals. We maximized to 100% the use of continuous veno-venous hemodiafiltration and doubled the percentage of patients using regional citrate anticoagulation. The delivered CRRT effluent dose (~ 30 ml/kg/h) and the delivered/prescribed effluent dose ratio (~ 0.89) remained stable within the study period. The average filter life increased from 26 to 31 h (p = 0.020), reducing the mean utilization of filters per patient from 3.56 to 2.67 (p = 0.054) despite similar CRRT duration and mortality rates. The number of CRRT access alarms per treatment day was reduced by 43%. The improvement in filter utilization translated into ~ 20,000 USD gross savings in filter cost per 100-patient receiving CRRT. We satisfactorily developed and implemented a quality assurance system for the provision of CRRT in the ICU that enabled sustainable tracking of CRRT deliverables and reduced filter resource utilization at our institution.
