Acute kidney injury (AKI) is common in hospitalized individuals, associated with adverse outcomes and increased cost. Continuous renal replacement therapy (CRRT) is used to treat critically ill patients with AKI, of which the cost in acute phase is higher than that of intermittent renal replacement therapy (IRRT). However, if treatment for subsequent chronic kidney disease or dialysis dependency following AKI is also considered, CRRT might be more cost-effective than IRRT. In this editorial, the cost and health economic evaluation of CRRT for critically ill patients is discussed.
ObjectiveTo explore the application effect of information-based circuit teaching mode for training refresher nurses in continuous renal replacement therapy (CRRT).MethodsCRRT refresher nurses studied in West China Hospital of Sichuan University from January 2016 to December 2019 were selected. The CRRT refresher nurses who were selected as the control group (studied from January 2016 to December 2017) accepted the conventional teaching method. The CRRT refresher nurses who were selected as the test group (studied from January 2018 to December 2019) accept the information-based combined with circuit teaching mode for teaching and training. After 6 months of training, the theoretical performance, operation performance, teaching satisfaction and the incidence of adverse events were compared between the two groups.ResultsA total of 112 CRRT refresher nurses were enrolled. Among them, there were 52 nurses in the control group and 60 in the test group. The scores of theory achievement (t=?2.421, P=0.017), operation achievement (t=?2.305, P=0.023) and teaching satisfaction [including teaching effect (t=?4.067, P<0.001), operation skill (t=?5.013, P<0.001), teaching mode (t=?5.589, P<0.001) and teaching content (t=?2.586, P<0.001)] of refresher nurses in the test group were higher than those in the control group. There was no significant difference between the control group (4 cases) and the test group (1 case) in the occurrence of adverse nursing events (adjusted χ2=1.169, P=0.280).ConclusionThe information-based circuit teaching mode has achieved good results in the teaching of CRRT refresher nurses, which is conducive to improving the post competency of CRRT refresher nurses.
Objective To estimate the cost of continuous renal replacement therapy (CRRT) in public hospitals and analyze the main influencing factors of the cost, in order to provide evidence for the optimal application of CRRT technology. Methods In March 2021, activity-based costing was used to estimate and analyze the cost of CRRT, the data of which were collected from 5 hospitals in Jiangsu, Zhejiang, Henan, Sichuan and Xinjiang, and single factor sensitivity analysis was used to find the main influencing factors of the cost. Results The hourly treatment costs of CRRT in the 5 hospitals ranged from 265.30 to 474.44 yuan, with an average of 376.81 yuan. The costs of manpower and filters accounted for the top two largest proportions, the manpower cost of continuous veno-venous hemofiltration and continuous veno-venous hemodiafiltration accounted for 22.90% and 21.51%, respectively, and the filters cost of the two types of CRRT accounted for 15.07% and 17.73%, respectively. The unit cost and cost composition varied greatly between hospitals. There were four factors affecting the unit cost, namely clinical operation, efficiency, price and patient, among which clinical operation difference was the primary factor leading to cost difference. Conclusions The application cost of CRRT technology varies greatly among hospitals, and there are many factors affecting the cost. Public hospitals face great pressure in cost control. It is necessary to strengthen the internal control operation management of public hospitals, establish CRRT clinical operation standards, and improve the quality of medical services in public hospitals.
ObjectiveTo observe the effect of continuous renal replacement therapy (CRRT) on serum phosphate level in patients after cardiac surgery.
MethodA single-center retrospective observational study was conducted on 30 patients received CRRT after cardiac surgery. There were 14 males and 16 females with mean age of 57.0±10.8 years (ranged 37-79 years). A total of 16 patients underwent CRRT with continuous veno-venous hemofiltration (CVVH), and 14 patients with continuous veno-venous hemodiafiltration (CVVHDF). The serum phosphate level was measured before treatment, at 24 h, and 48 h during therapy and 24 h after phosphate salt supplementation.
ResultsThe level of serum phosphate at 24 h and 48 h during CRRT was decreased (0.6±0.4 mmol/L vs. 0.4±0.2 mmol/L vs. 1.1±0.3 mmol/L, P<0.01). After intravenous phosphate salt supplementation, serum phosphate level got increased (0.6±0.3 mmol/L, P<0.01). There was no statistical difference in serum phosphate level between CVVH and CVVHDF (P>0.05).
ConclusionHypophosphatemia occurs frequently during CRRT, particularly with long treatment time. Phosphate salt supplementation is necessary. The dosage of the supplementation should be adjusted personally based on the regularly monitoring results of serum phosphate tests.
ObjectiveTo evaluate the efficacy of the continuous renal replacement therapy (CRRT) for acute kidney injury (AKI) after the surgery of type A aortic dissection.
MethodsWe retrospectively analyzed 58 hemodialysis patients with AKI after type A aortic dissection surgery in our hospital between January 2003 and January 2014.The 58 patients were divided into two groups including a bedside intermittent hemodialysis (IHD) group and a CRRT group based on the methods of hemodialysis. There were 38 patients with 29 males and 9 females at average age of 49.8± 13.7 years in the CRRT group. There were 20 patients in the IHD group with 14 males and 6 females at average age of 52.6± 11.0 years.
ResultsCompared with IHD, CRRT had significantly greater effect on reducing the simplified acute physiology scoring system (SAPS)Ⅱscore (Ftime=60.964, P=0.000; Ftime * group=3.178, P=0.041). However, there was no significant difference in reducing the acute tubular necrosis individual illness severity index (ATN-ISI) score between the two groups (Ftime=13.803, P=0.000; Ftime * group=0.222, P=0.951). Lower incidences of dialysis-related complications including hypotension (P=0.027) and acute congestive heart failure (P=0.011) were found in the CRRT group. There was no statistical difference in operation time (P=0.367) between the two groups. While statistical differences in duration of hospitalization in intensive care unit (P=0.006), in hospital time (P=0.047), frequency of dialysis (P=0.001), and dialysis time (P=0.039) were found between the two groups. However there were no significant differences in mortality during hospital (P=0.544)and incidences of recovery (P=0.056) between the two groups.
ConclusionCompared with IHD, CRRT had significantly positive effect on patients who suffered from AKI after type A aortic dissection surgery, which can help reduce incidences of dialysis-related complications, duration and cost of hospitalization in ICU.
Continuous renal replacement therapy (CRRT) is the treatment of choice for critically ill patients with hemodynamic instability who require renal replacement therapy. This review summarizes the impact of CRRT treatment on nutritional support in critically ill patients, including: energy increase caused by citrate-based anticoagulants, energy loss caused by glucose-free replacement fluid and dialysate, a large amount of amino acids loss in the effluent, and the influences on the way of lipid emulsion administration, capacity, electrolyte, vitamins, and trace elements. It is hoped that the intensive care unit doctors, nephrologists, and nutritionists can fully cooperate to determine the CRRT prescription and the nutritional support prescription.
Continuous renal replacement therapy (CRRT) is one of the major treatments for critically ill patients. With the development of information technology, the informatization and artificial intelligent of CRRT has received wide attention, which has promoted the optimization of CRRT in terms of workflow, teaching method as well as scientific research. Benefiting from the big data generated, artificial intelligence is expected to be applied in the precision treatment, quality control, timing of intervention, as well as prognosis assessment in severe AKI, so as to ultimately improve the therapeutic effect of CRRT among critically ill patients. This paper summarizes the information construction of CRRT and the research progress of artificial intelligence, which can be used as a reference for practitioners in kidney disease, critical medicine, emergency medicine and other related fields.
In continuous renal replacement therapy (CRRT), the combination of medicine and engineering is propelling advancements in therapeutic technology. By enhancing the biocompatibility and specific adsorption capabilities of the blood adsorption materials, the therapeutic efficacy of CRRT is augmented, leading to a reduction in adverse reactions for patients. Moreover, the application of big data and artificial intelligence in CRRT is continually being developed. Utilizing intelligent devices, data analysis, and machine learning, the initiation, monitoring, and formulation of CRRT treatment plans are optimized, providing clinical patients with more efficient and secure therapeutic options, thereby further improving clinical outcomes.
Currently, there is a lack of guidelines and consensuses on hospital infection prevention and control for continuous renal replacement therapy (CRRT) at home and aboard. Given that in-hospital infection control for CRRT differs from that for intermittent hemodialysis, the Nephrology Brunch of Sichuan International Medical Exchange & Promotion Association, in collaboration with West China Hospital of Sichuan University, has established an expert consensus group for CRRT hospital infection prevention and control. The group conducted systematic retrieval, data analysis, and expert consultation on the thematic content, and developed five topics: occupational protection for CRRT healthcare personnel, CRRT catheter-related infections, collection of CRRT blood/waste specimens, disinfection of CRRT machines, and utilization and disposal of CRRT consumables and waste. The aim is to standardize clinical practices, prevent nosocomial infections, and enhance awareness among healthcare personnel regarding infection prevention and control in CRRT settings.
Continuous renal replacement therapy (CRRT) is one of the important therapeutic techniques for critically ill patients. In recent years, the field of artificial intelligence has developed rapidly and has been widely applied in manufacturing, automotive, and even daily life. The development and application of artificial intelligence in the medical field are also advancing rapidly, and artificial intelligence radiographic imaging result judgment, pathological result judgment, patient prognosis prediction are gradually being used in clinical practice. The development of artificial intelligence in the field of CRRT has also made rapid progress. Therefore, this article will elaborate on the current application status of artificial intelligence in CRRT, as well as its future prospects in CRRT, so as to provide a reference for understanding the application of artificial intelligence in CRRT.
