ObjectiveTo construct a scientific, standardized, and consistent nursing service quality evaluation system for hemodialysis centers, and to provide scientific basis for the evaluation, improvement, and promotion of nursing service quality in hemodialysis centers.MethodsFrom October to December 2018, based on the Servqual model, combined with the particularity of hemodialysis center and relevant national policies and regulations, the indexes of nursing service quality were determined by Delphi method and precedence chart method, and the nursing service quality evaluation scale of hemodialysis center was established.ResultsThe established nursing service quality evaluation system for hemodialysis center was consisted of 7 items of first-level, 15 items of second-level, and 38 items of third-level. The effective recovery rate of expert letters was 93.75%, and the expert authority coefficient was 0.914. The Kendall coordination coefficients for the three levels of indicators were 0.570, 0.583, and 0.496 (P<0.01), and the variation coefficients for each level of indicators were between 0.000 and 0.179. Among the first-level indicators, the largest weight was security, and the smallest weight was effectiveness.ConclusionsThe evaluation system of nursing service quality for hemodialysis centers is scientific, reliable, and feasible. In view of the particularity of nursing service in hemodialysis centers, clear evaluation criteria are put forward, which can evaluate the service quality more comprehensively, scientifically, objectively, and directly, and improve and enhance the service level of hemodialysis centers according to the evaluation system.
ObjectiveTo compare the quality of life in the early stage of treatment in patients who accepted renal transplantation with those who still were undergoing long-term hemodialysis. MethodsPatients undergoing long-term hemodialysis in December 2011 and adult patients who planned to accept renal transplantation within 6 months were chosen to be our study subjects. The Medical Outcomes Study 36-item Short Form Health Survey Questionnaire (SF-36) was used for the study. After 6 months of following up, they were assessed with the same questionnaire again. Those hemodialysis patients who accepted renal transplantation within this period were divided into the intervention group. The quality of life between the two groups was compared then. ResultsA total of 124 end-stage renal failure patients were involved in our study, in which 79 patients successfully accepted renal transplantation (intervention group) and the other 45 patients who still underwent hemodialysis (control group). No other complications were observed during this period. There was no significant difference in life quality between the two groups before treatment (P>0.05). Six months after the treatment, SF-36 total score and each of the 8 dimension scores for the intervention group were all significantly higher than those for the control group (P<0.05). ConclusionRenal transplantation recipients have a totally better life quality than those who depend on hemodialysis.
ObjectiveTo explore the risk factors for central venous catheter (CVC)-related infections and its Countermeasures, as CVC is an important vascular access for blood purification and is widely used in clinical applications, but catheter-related infection is one of the common severe complications. MethodsWe retrospectively analyzed the clinical data of 725 patients with complicated infections of indwelling center venous double lumen catheter treated between January 2009 and December 2012. ResultsAmong all 725 cases, 15 had catheter-related infection. There were one case of subcutaneous tunnel infection (staphylococcus aureus by the secretion culture, negative for blood culture), and 14 cases of positive blood culture including 9 staphylococcus aureus cases, 3 escherichia coli cases, 1 colorless bacillus case and 1 stenotrophomonas maltophilia case. Eight cases were cured by antibiotic therapy while antibiotics were invalid in the other 7 cases resulting in tube withdrawing. ConclusionThe central venous catheter-related infections are related to medical service ability, catheter indwelling position, indwelling time, hemodialysis adequacy, patients' general condition and personal hygiene. Taking relative measures in view of each factor is the key to prevent infections.
Objective To assess the cost-utility study of renal transplantation compared with nemodialysis (HD) and peritoneal dialysis (PD). Methods A prospective study of end-stage renal disease patients was followed up for 3 months after renal replacement therapy. The study population included 196 patients (renal transplant [RT] n=63, hemodialysis [HD] n=82 and continious ambulatory peritoneal dialysis [CAPD] n=51) from 6 hospitals of Sichuan province. Health-related quality of life was assessed by using the WHOQOL-BRIEF questionnaire. Utility scores were obtained so as to conduct CUA (cost-utility analysis). Costs were collected from financial department and by patient interview. Results The utility values were 0.539 9± 0.013 for RT, 0.450 8± 0.014 for HD, 0.512 2±0.099 for CAPD, respectively. The mean direct cost of the first three months of renal transplant was significantly higher than dialysis (RT and CAPD). Over 3 months, the average cost per quality-adjusted life year (QALY) for patients after CAPD was lower than HD and RT. Compared to HD, incremental cost analysis showed that CAPD was more ecnomical than RT. Sensitive analysis showed that CAPD was more effective than RT when ΔQALY varied in the limit of 95% confidence interval. However, the cost-utility of RT vs HD and CAPD vs HD was varied with ΔQALY level. Conclusions Cost-utility analysis showed that CAPD was a more favorable cost-utility ratio when compared to RT at early stage RT vs HD and CAPD vs HD, but which cost-utility ratio is better, we can not draw a certain conclusion.
The formation of an arteriovenous fistual for dialysis by routine interrupted sutures anastomosing the vein and artery is difficult to perform and time-consuming. A new method, telescopic adhesive anastomosis was studied and applied in 10 hemodialysis patients, who were in need of an arteriovenous fistula. The external diameter of the vessels anastomosed was 2.40 +/- 0.20 mm (radial artery) or 2.40 +/- 0.35 mm (cephalic vein). After thorough debridement of the vascular ends, the arterial end was put in the venous lumen. In order to fix the telescopic vessels, two stitches were applied 180 degrees apart from each other and tied. Each stitch was inserted from vein (penetrating the whole wall) to artery (just through the adventitia and partial thickness of the media vasorum). The distance from the stitch to the edge of the vein was 0.5 mm, and that of the artery was approximated to the external diameter of the vessle. The medical adhesive was then applied for sealing the anastomotic adventitia. Ten seconds were given for the solidification of the adhesive. The patients were followed up for 8 months. The patency rate was 100%, and the rate of blood flow was more than 300 ml/min (measured by ultrasonography). It was shown that this method could be managed easily and quickly, and the so-formed fistula would fulfill the need of hemodialysis.
Tunnel-cuffed catheter catheters are one of the important means of vascular access for hemodialysis patients. Appropriate catheter placement methods and effective intervention measures can help improve the service life of tunnel catheters, reduce the incidence of complications, and ensure the quality of dialysis treatment. This article provides a review of the placement and maintenance of tunnel-cuffed catheters, with the aim of providing a reference for medical staff to perform tunnel-cuffed catheterization operations and reduce related complications. The placement of tunnel-cuffed catheters includes the type, location, and tip positioning of the catheter, the maintenance includes endovascular monitoring and use of disinfectants, dressings and ointments, use of sealing fluid, management of catheter complications, identification of individual differences and early assessment and screening.
Objective To assess the possible causes of acute pancreatitis (AP) in long term peritoneal dialysis (PD) and hemodialysis (HD) patients, and to discuss the diagnosis and treatment of AP in this kind of patients. Methods The clinical data of 9 cases of AP in PD and HD patients who were admitted in the hospital during January 1993 and January 2000 were analysed retrospectively. Results The serum levels of amylase of all the 9 cases were over three and a half times of upper limit value of healthy subjects. B mode ultrasound and CT scan examinations were useful for diagnosis of AP. Eight patients recovered very well with conservative treatment, while one patient who was diagnosed as acute severe pancreatitis and complicated with shock died. Conclusion Long term PD and HD patients are predisposing to develop AP. Diagnosis of AP in these patients primarily depends on the detection of serum amylase. Dialysis treatment is indispensable for cure of AP.
ObjectiveTo explore the role of arteriovenous axillary loop graft (AVALG) on chest for establishing hemodialysis access in patients with chronic renal failure. MethodsA retrospective analysis was made on the clinical data of 12 patients with chronic renal failure who underwent an AVALG on chest for hemodialysis access between December 2010 and May 2014. There were 2 males and 10 females with an average age of 65.25 years (range, 46-75 years). The main causes were chronic glomerulonephritis in 6 cases, diabetic nephropathy in 4 cases, and both kidney resection because of urinary tract tumors in 2 cases. The disease duration was 2-12 years (mean, 6 years). The 12 patients all underwent 5-14 times (mean, 7 times) failed prior vascular accesses [arteriovenous fistula (AVF）and arteriovenous graft (AVG)] leading to exhaustion of venous access sites on the upper extremities. ResultsThe AVALG on chest were functionally useful for hemodialysis access, 2-3 times per week, and the blood flow was 250-350 mL/minute; the average time for the first dialysis was 48 days (range, 42-93 days). All patients were followed up 12-54 months (mean, 20.92 months). There was no death during perioperative period. The primary patency rates at 6 and 12 months were 91.7% and 83.3% respectively, and the secondary patency rates at 6 and 12 months were both 100%. After operation, infection (1 case), thrombosis (2 cases), bleeding (2 cases), and swollen (1 case) occurred, which were all cured after corresponding treatment. ConclusionAVALG on chest is a supplementary option for chronic renal failure patients with inadequate upper extremity venous access sites after repeat occlusion.
During the medical rescue after Wenchuan earthquake, based on the design and implementation of the management process of blood purification equipment, we gave the top priority to those patients with post-disaster crush syndrome to ensure their hemodialytic treatment. Through strict management of blood purification technology, the outcomes of these patients have been fundamentally improved and the incidence of complications was substantially reduced. Safe and effective hemodialytic treatment have been administered to 77 patients with crush syndrome (813 case-times).
ObjectiveTo evaluate the safety and efficacy of second central venous catheterization in tunnel cuffed dialysis catheter (TCC) dysfunction with fibrin sheath.MethodA total of 14 maintenance hemodialysis patients who required second central venous catheterization were enrolled in West China Hospital of Sichuan University from June 2016 to June 2017 and the clinical information and procedure-related complications were recorded.ResultsAll of the 14 patients were successfully performed with second central venous catheterization, of whom 4 cases had superior vena cava cannulation, 7 cases had right brachiocephalic vein cannulation, 2 cases had internal jugular vein cannulation, and 1 case had external jugular vein cannulation. No procedure-related major complication occurred. During the follow-up, catheter malfunction occurred in 2 cases, which improved by urokinase seal and catheter change, respectively. The rest patients’ catheter function remained normal.ConclusionsWith increasing difficult to construction and maintenance of vascular access, preservation of central vein resource is of high importance. For patients with TCC dysfunction with fibrin sheath, second central venous catheterization based on percutaneous brachiocephalic vein or superior vena cava cannulation is a safe and effective method to establish the lifeline for hemodialysis patients.
