Validation of arteriovenous access stage (AVAS) classification: a prospective, international multicentre study.

Background: The arteriovenous access stage (AVAS) classification provides evaluation of upper extremity vessels for vascular access (VA) suitability. It divides patients into classes within three main groups: suitable for native fistula (AVAS1) or prosthetic graft (AVAS2), and patients not suitable for conventional native or prosthetic VA (AVAS3). We validated this system on a prospective dataset. Methods: A prospective, international observational study (NCT04796558) involved 11 centres from 8 countries. Patient recruitment was from March 2021 to January 2024. Demographic data, risk factors, vessels parameters, VA types, AVAS class and early VA failure were collected. Percentage agreement was used to assess predictive ability of AVAS (comparison of AVAS and created VA) and consistency of AVAS assessment between evaluators. Pearson's Chi-squared test was used for comparison of early failure rate of conventional (predicted by AVAS) and unconventional (not predicted by AVAS) VA. Results: From 1034 enrolled patients, 935 had arteriovenous fistula or graft, 99 patients did not undergo VA creation due opting for alternative renal replacement therapies, experiencing health complications, death or non-compliance. AVAS1 had 91.2%, AVAS2 7.2% and AVAS3 1.6% of patients. Agreement between evaluators was 89%. The most frequently created VAs were radial-cephalic (46%) and brachial-cephalic (27%) fistulae. The accuracy of AVAS versus created access was 79%. In comparison, VA predicted by clinicians versus created access was 62.1%. Inaccuracy of AVAS prediction was more common with higher AVAS classes, and the most common reason for inaccuracy was creation of distal VA despite less favourable anatomy (17%). Patients with unconventional VA had higher early failure rate than patients with conventional VA (20% vs 9.3%, respectively, P = .002). Conclusion: AVAS is effective in predicting VA creation, but overall accuracy is reduced at higher AVAS classes when the complexity of decision-making increases and proximal vessels require preservation. When AVAS was followed by clinicians, early failure was significantly decreased.

Enhancing Infection Control in Dialysis at a Resource Limited Public Healthcare Institute: A Cross-Sectional Study on Microbiological Quality Assessment of Dialysis Water andDialysate.

PURPOSE: To evaluate the microbiological quality of dialysis water and dialysate samples from hemodialysis units at a tertiary care government hospital and to assess the use of culture, endotoxin and periodicity of testing these assays to guide the actions of monitoring the quality of hemodialysis fluids, implement preventive and corrective actions, and improve the safety and outcomes of the dialysis process. METHODS: A cross-sectional study was conducted at a 250-bedded super-specialty government hospital with a 24/7 hemodialysis unit equipped with 40 dialysis machines. Dialysis water and dialysate samples were collected monthly and analyzed for microbial contamination and endotoxin levels as per AAMI guidelines. Bacterial cultures were done using Reasoner's Agar plates, and endotoxin analysis was performed using gel clot assay. Interpretation of results was based on predefined thresholds. RESULTS: Among the 740 samples processed for microbial culture 19.6% and 80.4%wereunacceptable and acceptable respectively.Among the acceptable samples 10.5% were at action level. At the end of 2 days of incubation, 15.2%dialysis water samples and 5.1%dialysate samples had unacceptable levels of bacterial colonies and at 5days additional 10.6% dialysis water samples and 7.7%dialysate samples were unacceptable. 21.5% of the samples tested for endotoxin had unacceptable levels. CONCLUSIONS: Regular monitoring of water quality in government healthcare hemodialysis units is crucial for quality of care, timely preventive and corrective actions for mitigating adverse outcomes. Processing cultures for 5-7 days is essential for detecting all contaminated specimens. While there might be a link between endotoxin levels and bacterial contamination, both endotoxin testing and bacterial culture independently are vital for evaluating water quality in dialysis settings. A comprehensive approach integrating various testing methods is necessary to uphold patient safety and enable necessary improvements.

Vision loss and diabetic retinopathy prevalence and risk among a cohort of Indigenous and non-Indigenous Australians with type 2 diabetes receiving renal haemodialysis treatment: The retinopathy in people currently on renal dialysis (RiPCORD) study.

AIMS: Diabetic nephropathy, vision loss and diabetic retinopathy (DR) are frequent comorbidities among individuals with type 2 diabetes (T2D). The Retinopathy in People Currently On Renal Dialysis (RiPCORD) study sought to examine the epidemiology and risk of vision impairment (VI) and DR among a cohort of Indigenous and non-Indigenous Australians with T2D currently receiving haemodialysis for end-stage renal failure (ESRF). METHODS: A total of 106 Indigenous and 109 non-Indigenous Australians were recruited in RiPCORD across five haemodialysis centres in urban and remote settings. Clinical assessments, questionnaires and medical record data determined the rates of ocular complications and risk factor profiles. RESULTS: Prevalence rates include unilateral VI, 23.5 %; bilateral VI, 11.7 %; unilateral blindness, 14.2 %; and bilateral blindness, 3.7 %, with no significant differences between sub-cohorts (p=0.30). DR prevalence rates were 78.0 % among non-Indigenous Australians and 93.1 % among Indigenous Australians (p=<0.001). Non-Indigenous ethnicity (OR: 0.28) and pre-dialysis diastolic blood pressure (OR: 0.84 per 10-mmHg) were protective, while peripheral vascular disease (OR: 2.79) increased DR risk. CONCLUSIONS: Ocular complications among individuals with T2D and ESRF are disproportionately high, especially for Indigenous Australians, and beyond what can be accounted for by risk factor variation. Findings suggest a need to improve screening and preventative efforts within this high-risk population group.

Cost-effectiveness of bioimpedance-guided fluid management in patients undergoing haemodialysis: the BISTRO RCT.

Background: The BioImpedance Spectroscopy to maintain Renal Output randomised controlled trial investigated the effect of bioimpedance spectroscopy added to a standardised fluid management protocol on the risk of anuria and preservation of residual kidney function (primary trial outcomes) in incident haemodialysis patients. Despite the economic burden of kidney disease, the cost-effectiveness of using bioimpedance measurements to guide fluid management in haemodialysis is not known. Objectives: To assess the cost-effectiveness of bioimpedance-guided fluid management against current fluid management without bioimpedance. Design: Within-trial economic evaluation (cost-utility analysis) carried out alongside the open-label, multicentre BioImpedance Spectroscopy to maintain Renal Output randomised controlled trial. Setting: Thirty-four United Kingdom outpatient haemodialysis centres, both main and satellite units, and their associated inpatient hospitals. Participants: Four hundred and thirty-nine adult haemodialysis patients with > 500 ml urine/day or residual glomerular filtration rate > 3 ml/minute/1.73 m2. Intervention: The study intervention was the incorporation of bioimpedance technology-derived information about body composition into the clinical assessment of fluid status in patients with residual kidney function undergoing haemodialysis. Bioimpedance measurements were used in conjunction with usual clinical judgement to set a target weight that would avoid excessive fluid depletion at the end of a dialysis session. Main outcome measures: The primary outcome measure of the BioImpedance Spectroscopy to maintain Renal Output economic evaluation was incremental cost per additional quality-adjusted life-year gained over 24 months following randomisation. In the main (base-case) analysis, this was calculated from the perspective of the National Health Service and Personal Social Services. Sensitivity analyses explored the impact of different scenarios, sources of resource use data and value sets. Results: The bioimpedance-guided fluid management group was associated with £382 lower average cost per patient (95% CI -£3319 to £2556) and 0.043 more quality-adjusted life-years (95% CI -0.019 to 0.105) compared with the current fluid management group, with neither values being statistically significant. The probability of bioimpedance-guided fluid management being cost-effective was 76% and 83% at commonly cited willingness-to-pay threshold of £20,000 and £30,000 per quality-adjusted life-year gained, respectively. The results remained robust to a series of sensitivity analyses. Limitations: The missing data level was high for some resource use categories collected through case report forms, due to COVID-19 disruptions and a significant dropout rate in the informing BioImpedance Spectroscopy to maintain Renal Output trial. Conclusions: Compared with current fluid management, bioimpedance-guided fluid management produced a marginal reduction in costs and a small improvement in quality-adjusted life-years. Results from both the base-case and sensitivity analyses suggested that use of bioimpedance is likely to be cost-effective. Future work: Future work exploring the association between primary outcomes and longer-term survival would be useful. Should an important link be established, and relevant evidence becomes available, it would be informative to determine whether and how this might affect longer-term costs and benefits associated with bioimpedance-guided fluid management. Funding details: This article presents independent research funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme as award number HTA 14/216/01 (NIHR136142).

'Bioimpedance' is a measure of how difficult it is for an electric current to pass through a biological object. Bioimpedance is used in devices that assess fluid status (over- or under-hydration) because it is very sensitive to the amount of water in tissue. Bioimpedance can be used in addition to clinical judgement when deciding how much water should be removed from someone with kidney failure during a dialysis treatment session. This is the first study to examine whether using this treatment represents a cost-effective use of National Health Service resources. We carried out an economic evaluation within a large randomised controlled trial in patients with kidney disease undergoing haemodialysis. We calculated the additional costs and quality-adjusted life-years (a measure that combines quality and quantity of life) using established methods. Over 2 years, our study showed that taking into account bioimpedance measurements about target weight resulted in slightly lower costs and marginally more quality-adjusted life-years, although there is uncertainty around these findings.

Impact of arteriovenous fistula aneurysms on a UK dialysis populations' perception of vascular access.

BACKGROUND: Clinically-oriented outcome measures are increasingly being recognized as lacking in consideration of factors important to patients. There is an emerging move of guideline bodies advocating a more patient-centred approach. Aneurysms in autogenous arteriovenous fistula (AVF) can be considered unsightly and a constant reminder for patients of their dependence on dialysis. However, their impact on patient's perception has not previously been reported. METHODS: Between April 2017-18, the Vascular Access Questionnaire (VAQ) was administered to prevalent haemodialysis patients across ten dialysis units via structured interviews, as part of a quality improvement project. Data for the subgroup of patients with aneurysmal AVF (categorised as per classification by Valenti et al.), were retrospectively evaluated and compared to the wider cohort. RESULTS: Data were collected for 539 patients (median age: 66 years; 59% male), of whom 195 (36%) had aneurysmal AVF, with Type 2 morphology (cannulation site) being the most common (75%). Duration of AVF was found to be significantly associated with aneurysmal development, with estimated likelihoods of 11%, 43% and 61% after one, five and ten years, respectively. Interestingly, patients with diabetes had a significantly lower prevalence of aneurysmal development than those that were non-diabetic (25% vs. 43%, p < 0.001). Overall VAQ scores were not found to differ significantly by aneurysm status (p = 0.816) or across morphology types (p = 0.277). However, patients with aneurysmal AVF were significantly more concerned with the appearance of their AVF (p < 0.001) than the wider cohort. Despite this, patients with aneurysmal AVF gave significantly higher scores for satisfaction and ease of use and lower scores for bruising and clotting (p < 0.05). CONCLUSIONS: Aneurysmal AVF are often cited as an important factor by patients for not proceeding with fistula formation. In this evaluation of patient reported experiences, those with aneurysmal AVF reported high satisfaction levels. This may help clinicians highlight positive patient reported outcomes of aneurysmal AVF during preprocedural consent processes.

A haemodialysis catheter misplaced due to central venous stenosis: A case report.

Chronic kidney disease has become a significant global health issue, with some individuals progressing to endstage renal disease (ESRD) and requiring renal replacement therapy. For ESRD patients undergoing haemodialysis, the first step is to establish vascular access. In emergency situations, inserting a haemodialysis catheter (HDC) into the central vein is often the most appropriate approach; the right internal jugular vein (IJV) is considered the optimal site for catheterisation. However, catheter placement in the right IJV can sometimes lead to inadvertent entry into an abnormal position. Herein, we present a unique case in which the tip of the HDC was noted to have misplaced into the left IJV due to the patient's multiple central venous stenosis (CVS). This case highlights the clinical manifestation of HDC misplacement, with CVS being the underlying cause. Therefore, healthcare providers should pay adequate attention to CVS.

Perspectives of Chinese nephrology nurses on discussing sexual dysfunction with patients receiving haemodialysis: A qualitative study.

BACKGROUND: The study underscores the crucial yet often neglected issue of sexual dysfunction in haemodialysis patients. Despite nephrology nurses'close relationships with patients, there is a significant communication gap on this topic. In China, limited research highlights the need for further study. OBJECTIVE: To describe the perspectives of Chinese nephrology nurses on discussing sexual dysfunction with patients receiving haemodialysis. DESIGN: A qualitative descriptive study. PARTICIPANTS: Ten Chinese nephrology nurses from a tertiary public hospital in Guizhou province, China. APPROACH: Semistructured interviews were conducted using an interview guide. Qualitative content analysis approach was utilised in analysis. RESULTS: There were five themes described: (1) lack of training in sexual education, as nephrology nurses described never being trained to manage patients' sexual health issues; (2) discomfort when discussing sexual topics, Chinese nephrology nurses found the topic of sexual dysfunction embarrassing and avoided discussing it; (3) sexual dysfunction viewed as a nonurgent topic, nephrology nurses prioritise physical health to aid patient survival; (4) belief in physicians as ultimate care advisors, nephrology nurses believed that doctors should handle discussions on sexually related topics; and (5) lack of a suitable environment for discussing sexual dysfunction, nephrology nurses viewed sex as a private matter, inappropriate for discussion in a public unit. CONCLUSION: The study identifies barriers to discussing sexual dysfunction in healthcare, including provider knowledge deficits, discomfort and lack of supportive environments. It recommends specialised training and conducive settings to improve communication in renal care. Future research should evaluate the effectiveness of these interventions.

An unusual case of Herbaspirillum huttiense bacteraemia in a haemodialysis patient.

Herbaspirillum spp. is a common environmental bacterium usually found in soil, plant roots, and water. It is rarely associated with infection in immunocompromised patients, and rarely reported infections in immunocompetent patients. We report the first case of a Herbaspirillum huttiense bacteraemia in a non-neutropenic home haemodialysis patient. A 57-year-old male presented to our hospital with a 3-day history of malaise, fevers, rigours, and anorexia following dialysis through his central line. On examination, he was pyrexic (temperature 38.7°C) with splinter haemorrhages noted, but no other signs of infection were present. Blood cultures revealed a polymicrobial infection, with Serratia liquefaciens and Corynebacterium jeikeium isolated from the central line and Herbaspirillum sp. was isolated from both the central line and a peripheral culture. A later peripheral blood culture following central line removal isolated Herbaspirillum huttiense. Regular biological testing of his home water supply and dialysate detected no colony forming units of non-fermenting gram-negative bacilli. He was initially treated with ceftriaxone and vancomycin initially, followed by ertapenem and vancomycin. Intravenous antibiotics were ceased following 5 days after central line removal and he made an uneventful recovery.

[Clinical Thermography for the Management of Hemodialysis Vascular Access].

The arteriovenous fistula (AVF) represents the favorite vascular access in individuals with chronic kidney disease (CKD). Because AVF is a guarantee of survival for these patients, proper surgical packing and a timely follow-up program is crucial. Although a good objective examination of the limb site of FAV provides useful information both in planning the fistula surgery and in its surveillance and monitoring, it is now well established that the advent of instrumental diagnostics (ultrasonography, digital angiography, Angio-TC, MRI) has contributed significantly to improving primary and secondary patency of FAV and early diagnosis of vascular access complications. In this area, clinical thermography, a noninvasive and nondestructive diagnostic technique for assessing minute surface temperature differences, has shown good potential for the assessment of AVF. In fact, thermographic analysis of a limb site of AVF shows an increase in temperature at the site of the anastomosis and along the course of the arterialized vein. In this article we report our experience on the use of thermography in preoperative evaluation and postoperative surgical packing of an AVF. Further studies could validate the use of clinical thermography as a diagnostic technique to be used in the field of hemodialysis vascular accesses.

The impact of depression on platelet activation, cardiocerebral vascular events and arteriovenous fistula dysfunction in patients undergoing haemodialysis.

Depression is a common psychiatric disorder among patients undergoing maintenance haemodialysis (MHD). Depression may reportedly contribute to poor prognosis in several ways, including its effects on platelet function. We hypothesised that depression contributes to the occurrence of cardiocerebral vascular events (CCVE) and dysfunction of arteriovenous fistula (DAVF) in patients undergoing MHD through its effects on platelets. In this prospective cohort study, patients undergoing MHD were recruited and divided into depression and non-depression groups according to their Hamilton Depression Scale (HAMD) scores. The 286 enrolled patients had 103 occurrences of depressive symptoms (prevalence = 36.01%). Compared with the non-depression group, depression group had a significantly higher cumulative prevalence of CCVE and DAVF during follow-up. Cox regression analysis indicated that higher HAMD scores and lower plasma platelet distribution width (PDW) were common risk factors for CCVE and DAVF. Furthermore, HAMD scores were significantly negatively correlated with plasma PDW and was the main variable affecting changes in PDW, as indicated by multiple linear regression analysis. Depression may increase the risk of CCVE and DAVF in patients undergoing MHD by activating platelets. Plasma PDW may be a convenient indicator of platelet activation status and may predict the risk of CCVE and DAVF.

The relationship between self-care behaviours regarding arteriovenous fistula and the fear of fistula failure in individuals receiving haemodialysis treatment.

Background: Many problems regarding the self-care behaviours of haemodialysis patients are recognised; however, the fear experienced by the patients cannot be adequately explained. Aims: This study was conducted to determine the relationship between self-care behaviours related to arteriovenous fistula and fear of fistula failure in individuals receiving haemodialysis treatment. Methods: In this descriptive and relational study, 259 patients who met the inclusion criteria constituted the sample of the study. A multiple regression analysis enter model was used to evaluate the predictive power of the Self-Care Behaviours in Arteriovenous Fistula Scale. Results: It was found that the primary source of fear related to the fistula was the fear of fistula failure with a rate of 79.5%, and the patients who had this fear had a lower mean self-care scale score. The variables account for 12% of the self-care situation, and it is seen that the model is significant. Conclusions: It was concluded that increasing the fear of failure decreased the self-care score. This study is important for raising awareness among nurses regarding the fear of fistula failure. Nurses must provide appropriate care for vascular access and try to alleviate patients' anxiety and fears by listening to them.

Reducing the carbon footprint for a 30-bed haemodialysis unit by changing the delivery of acid concentrate supplied by individual 5 L containers to a central delivery system.

BACKGROUND: Haemodialysis treatments generate greenhouse gas (GHG) emissions mainly as a result of the equipment, consumables and pharmaceuticals required. An internal audit demonstrated a 33% wastage of acid concentrate when using individual 5.0 L containers at a 1:44 dilution ratio. We therefore investigated whether changing the delivery system for acid concentrate would reduce wastage and any associated greenhouse gas emissions. METHODS: We calculated the difference for a 30-bed dialysis unit between receiving acid concentrate in single-use 5.0 L plastic containers versus bulk delivery for a central acid delivery system connected to the dialysis machines. Estimates of carbon dioxide equivalent (CO2e) emissions were made using the United Kingdom government database and other sources. RESULTS: A 30-station dialysis unit functioning at maximum capacity (3 shifts and 6 days/week), switching to bulk delivery and central acid delivery could realise an approximate total reduction of 33,841 kgCO2e/year; in reduced product wastage, saving 6192 kgCO2e, 5205 kgCO2e from fewer deliveries, and 22,444 kgCO2e saving from a reduction in packaging and waste generated, which equates approximately to a one tonne reduction in CO2e emissions per dialysis station/year. CONCLUSIONS: Switching from delivering acid concentrate in individual 5.0 L containers to a central acid delivery system can result in substantial reductions in CO2e emissions within a dialysis clinic. The emission savings from reducing the single-use plastic packaging greatly outweigh any gains from eliminating wastage of acid concentrate. Dialysis companies and clinicians should consider reviewing the design of current and future dialysis facilities and policies to determine whether reductions in CO2e emissions can be made.

Exploring the correlation between periodontal disease and serum biomarkers in haemodialysis patients.

BACKGROUND: Patients undergoing haemodialysis are more susceptible to infectious diseases, including periodontitis. This study aimed to investigate the Correlation between periodontal disease and serum markers in Yemeni haemodialysis patients. METHODS: A cross-sectional study was conducted on a sample of 70 haemodialysis patients. Patient interviews, clinical examinations, and laboratory tests were performed to collect data. Serum levels of albumin, calcium, phosphorus, haemoglobin, ferritin, and creatinine were measured, with separate measurements for cystatin C The association between categorical variables was assessed using the chi-square test and Pearson's correlation coefficient, considering a significance level of p < 0.05. RESULTS: Significant correlations were found between serum biomarkers and periodontal clinical parameters. Phosphorus, creatinine, albumin, ferritin, and creatinine levels correlated significantly with the Plaque Index (p < 0.001, p < 0.001, p = 0.015, p = 0.018, and p = 0.03). While the Ferritin level showed significant correlations with both the Plaque Index and Miller Classes (r = 0.281, p = 0.018 and r = 0.258, p = 0.031), respectively. The Calcium level showed a significant correlation with the Gingival Index (r = 0.266, p = 0.027). Cystatin C level was statistically correlated with mobility (r = 0.258, p = 0.031). Also, the result showed a significant correlation between Creatinine levels and Periodontitis (r = 0.26, p = 0.03). CONCLUSION: This study provides evidence of a strong association between periodontal disease and chronic kidney disease in Yemeni haemodialysis patients. The findings emphasize the significance of maintaining good oral health in the care of haemodialysis patients.

Out-of-pocket expenses and healthcare service utilisation among maintenance haemodialysis patients: A study at a tertiary care hospital in Udupi, Karnataka.

Background: Financial burdens faced by patients in India suffering from chronic kidney disease (CKD) are linked to healthcare access and inadequate insurance coverage. This study analyses out-of-pocket expenses and explores their healthcare utilisation patterns. Materials and Method: This time-bound hospital-based cross-sectional study was conducted in a tertiary care hospital in Udupi district, Karnataka, among patients who have undergone haemodialysis (HD) treatment for at least a year. Following ethics approval and CTRI registration, informed consent was obtained from all the patients prior to data collection. Result: The study involved 109 HD patients. The direct medical and non-medical costs incurred by HD patients were Rs 9,400 (IQR = 13,700) and Rs 3,200 (IQR = 2,000), respectively. The monthly health-related OOPE was Rs 16672.0 (IQR = 14,630.0). Overall, 103 (94.5%) individuals had been hospitalised since they began HD, and 50.5% of patients were hospitalised within the past year. On linear regression analysis, it was observed that the joint monthly income (ß 0.134, 95% CI 0.007 - 0.182, P value = 0.048), number of dialyses per week (ß 1.14, 95% CI 7541.5 - 16551.07, P value < 0.001), and social security (ß -1.02, 95% CI -13463.0 - 7982.56, P value < 0.001) exhibited significant correlations and served as predictors for household out-of-pocket expenditure (HROOPE) experienced by the patients. Conclusion: The study concludes that people receiving HD incur a considerable financial cost. Additionally, the CKD population uses healthcare services at a notable rate, including frequent hospital stays, visits to outpatient departments (OPDs), and emergency treatment, underscoring the pressing need for an increase in insurance coverage.

Depression and Quality of Life Among Haemodialysis Patients.

Introduction: Depression is likely to be the most common psychopathology in haemodialysis patients. It might affect their adherence to treatment and is associated with increased morbidity and mortality. However, the prevalence of depression in haemodialysis patients has not been definitively determined, and it is generally underdiagnosed and undertreated. Chronic renal failure (CRF) patients have diminished quality of life (QOL) scores compared with healthy persons. Moreover, patients on haemodialysis might have worse QOL than those on peritoneal dialysis. Objectives: To assess the level of depression and quality of life among haemodialysis patients. Methodology: The research design adopted for this study was quantitative method. The population includes patient undergoing haemodialysis in SMCH. The sample size was 60 selected through convenience sampling technique on the basis of criteria. Result: The findings revealed that 30 (50%) had severe depression, 26 (43.34%) had moderate depression, and 2 (3.33%) had borderline clinical depression and extreme depression, respectively. The mean score of overall quality of life score among haemodialysis patients was 34.66 ± 7.16. Conclusion: The analysis revealed that haemodialysis patients had severe to moderate depression, which in turn reduces the quality of life of the haemodialysis patients.

Association of the modified creatinine index with quality of life in haemodialysis patients.

Aims/Background The evaluation of health-related quality of life in patients undergoing maintenance haemodialysis has garnered increasing attention. The modified creatinine index, a surrogate marker for muscle mass, has been linked to various clinical outcomes. However, the relationship between modified creatinine index and health-related quality of life in maintenance haemodialysis patients remains unclear. This study aims to elucidate the association between modified creatinine index and health-related quality of life in individuals receiving maintenance haemodialysis. Methods This cross-sectional study included 217 maintenance haemodialysis patients. Health-related quality of life was assessed using the Kidney Disease Quality of Life Instrument. Collected data included general patient information, laboratory results, and haemodialysis-related parameters. The modified creatinine index was calculated based on gender, age, single-pool Kt/V (spKt/V), and pre-dialysis serum creatinine levels. Multiple linear regression models and smooth curve fitting were used to investigate the relationship between modified creatinine index and health-related quality of life. Subgroup analyses and interaction tests were performed to identify potential effect modifiers. Results The 217 maintenance haemodialysis patients had a mean age of 53.66±13.15 years and a median dialysis vintage of 39 (25-84) months; 120 (55.30%) were male. The mean health-related quality of life score was 55.76±10.33, and the mean modified creatinine index was 22.72±2.95 mg/kg/day. After adjusting for confounding factors, an increase in modified creatinine index was associated with an improvement in health-related quality of life (ß=0.55, 95% CI: 0.04, 1.06, p = 0.033). No nonlinear relationship was identified between modified creatinine index and health-related quality of life by smooth curve fitting. Subgroup and interaction analyses indicated that the relationship between modified creatinine index and health-related quality of life was stable and not significantly influenced by age, gender, dialysis vintage, diabetes status, or body mass index (p > 0.05). Conclusion Modified creatinine index is positively correlated with health-related quality of life in maintenance haemodialysis patients, suggesting its potential utility in evaluating patient quality of life. Modified creatinine index could be clinically useful to improve the predictability of health-related quality of life in maintenance haemodialysis patients.

Case series of using automated insulin delivery to improve glycaemic control in people with type 1 diabetes and end stage kidney disease on haemodialysis.

Automated insulin delivery (AID) in people with type 1 diabetes (pwT1D) and end-stage kidney disease (ESKD) on haemodialysis (HD) has not been reported previously. We describe practical considerations and our findings in four pwT1D on HD for ESKD where AID was safely implemented, with significant improvements in time in range.

All Good Without Anything Good. Beyond Survival: Understanding the Psychosocial Experiences of Individuals With Chronic Kidney Disease and Their Caregivers in Sri Lanka.

AIM: This study aims to explore the experiences of individuals with chronic kidney disease (CKD) undergoing haemodialysis and their caregivers, focusing on the disease's impact and the treatment process. BACKGROUND: In Sri Lanka, CKD is a growing health concern, particularly affecting farming communities and contributing to the strain on the biomedical healthcare system. Despite increasing awareness of CKD's physical implications, its psychosocial impact remains underexplored. This study seeks to fill this gap, aiming to inform culturally sensitive interventions and improve the healthcare system's responsiveness to the unique needs of Sinhala Buddhist individuals with CKD and their caregivers. DESIGN: An exploratory qualitative study. METHOD: Semistructured interviews were conducted with 10 individuals undergoing haemodialysis and 5 caregivers at a dialysis unit. The interviews were audio-recorded, transcribed and analysed using conventional qualitative content analysis. FINDINGS: The analysis revealed three interrelated main themes: (1) impact on standard of living (quality of life), (2) coping strategies and (3) medical experience, with a notable influence of traditional beliefs and practices. CONCLUSION: The findings highlight the need for a holistic approach to CKD management that integrates physical, emotional, psychological and social aspects, considering the significant role of traditional influences. Further research is essential to develop effective interventions that can enhance the quality of life for CKD. PATIENT OR PUBLIC CONTRIBUTION: The lived experiences of Sinhala Buddhist individuals with CKD and their caregivers served as a cornerstone, providing profound insights into the impact of the condition on their lives. Throughout the study, these participants played an instrumental role in refining the research's cultural sensitivity and relevance. Their engagement extended beyond the data collection phase to encompass feedback sessions, where they actively shared their perspectives. This ongoing collaboration ensured the study's depth and applicability to real-world experiences. By actively involving those directly affected by CKD, this collaborative approach safeguards that the study remains rooted in their voices and addresses their unique needs. REPORTING METHOD: This study adhered to relevant EQUATOR guidelines (the COREQ checklist). TRIAL REGISTRATION: This study is not a clinical trial, and thus, registration is not applicable.

Screening for depression in chronic haemodialysis patients as a part of care in dialysis setting: a cross-sectional study.

Background: Depressive disorder is common among haemodialysis patients. The purpose of this study was to explore approaches to diagnosing depression in the context of a real-life setting, with the view of creating practical recommendations. It also aimed to evaluate the prevalence of depression and dementia. Methods: We conducted a cross-sectional study in two Dialysis Centres in Poland. Cognitive functions were evaluated using Mini-Mental State Examination (MMSE). The screening for depressive symptoms was assessed using Beck Depression Inventory II (BDI-II). The diagnosis of major depressive disorder was confirmed by a psychiatrist using Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5). Sociodemographic and clinical data were also collected. Results: Initially, 136 patients agreed to participate in the study. Dementia was found in 13% of the study group. Sixty-two patients did not agree to perform all the proposed tests and were not included in the analysis, which eventually consisted of 70 patients. According to BDI-II, depressive symptoms were present in 35.7% of patients, while the diagnosis of major depressive disorder (MDD) was confirmed by the psychiatrist in 25.7%. According to the ROC analysis the optimal cut-off score for diagnosing MDD using BDI-II was ≥13 points. Conclusions: This study suggests that the regular screening for depressive symptoms, followed by a psychiatric consultation in selected patients, might improve diagnosing depression with the goal of achieving a higher quality of life and a lower mortality rate. It may also be a cost-effective model for the management of depression among the haemodialysis population.
