A combined strength and balance exercise program to decrease falls risk in dialysis patients : a feasibility study

People suffering end-stage kidney disease receiving hemodialysis have a greater risk of falling and suffering debilitating injuries. The purpose of this study was to examine the feasibility and impact of a combined strength and balance exercise intervention on falls risk in hemodialysis patients. Twenty-four adults (mean age = 67.8 yrs) from two Australian outpatient hemodialysis clinics completed the intervention. Falls risk was measured using the Physiological Profile Assessment (PPA). There was a significant reduction in the median overall falls risk z-score from 1.67 to .52 (z = -3.11, P<.008; r = .45). Median reaction time improved from .30 to .26 sec (z = -2.86, P<.008; r = .41). A strength and balance intervention to reduce the falls risk for dialysis patients is feasible and may reduce falls risk for at risk patients.

Nutrition screening by nurses in dialysis

Aims and objectives : To determine whether a nurse-completed dialysis nutritional screening tool improves referral rates for nutritional support and compare nutrition sensitive biochemical indices, mortality rates and patient-centred quality of life outcomes between referred and non-referred dialysis patients.

Background : People with chronic kidney disease requiring dialysis are nutritionally at risk. Nutrition screening has been shown to identify dialysis patients who are nutritionally at risk to refer to dietitian expertise.

Design : Prospective cluster-randomised control trial.

Methods : Monthly nurse-completed nutrition screening was completed for six consecutive months using a validated four-item instrument measuring weight change, serum phosphate, serum potassium and appetite. Participants (n = 81) were haemodialysis patients from four satellite haemodialysis centres in one Australian metropolitan health service. Primary outcome measure was rate of referral to dietetic services for nutrition support for intervention vs. control groups at six months. Secondary outcome measures were blood pressure, biochemical indices and mortality for referred vs. non-referred patients at six and nine months, and generic and dialysis-specific quality of life for referred vs. non-referred at nine months was examined.

Results : There were three times as many dietetic referrals in the intervention group than in the control group (26·3 vs. 9·3%). Serum phosphate increased significantly more in the referred patients than the non-referred patients. There were no clinically significant changes between groups in quality of life, blood pressure, mortality rates or other biochemical indices at either six or nine months.

Conclusion : Nurse-completed nutritional screening can lead to appropriate dietetic referrals for nutritional support by nutritional expert clinicians.

Relevance to clinical practice : This study is the first to demonstrate that monthly systematic nurse-completed nutritional screening can facilitate appropriate dietetic referrals that may lead to increased nutritional care for people in satellite dialysis centres.

Using images to communicate the hidden struggles of life on dialysis

Background Nurse‐patient communication in the hemodialysis context is unique given the amount of time spent together in a confined clinical room. Poor communication may lead to low-quality nursing care and undesirable patient outcomes.

Aim To explore the use of images as a visual communication technique for nurses and patients in the hemodialysis context.

Methods Descriptive qualitative design. Fifty-two cards containing specific photos, illustrations, and words were used to facilitate conversations about being on hemodialysis between patients (n = 9) and two nurse interviewers. Interview transcripts were thematically analysed.

Findings An overall theme titled ‘revealing the hidden struggles of living on dialysis’ conceptually captured three sub-themes: (1) the increased importance of relationships; (2) the struggle with money; and (3) quality over quantity of life. The cards assisted in uncovering these often covert (to nurses) aspects of dialysis patients' lives.

Conclusion Nurses may need to be aware of the dialysis patients' hidden struggles which include the importance of relationships, financial issues, and the importance of quality aspects such as travel. The use of images may assist in revealing the important issues for each patient struggling with the restrictive life that is imposed by dialysis.

A haemodialysis exercise program using novel exercise equipment

This study explored whether an exercise programme for haemodialysis patients, including the use of a purpose built dialysis exercise machine, would improve quality of life (QoL), nutrition, physical function and biochemical indices. QoL, and biochemical indices were measured at 6 months and nutrition was measured at 12 months. Physical function was measured at 4, 8 and 12 months. Results showed improvement in physical function tests a decrease in serum phosphate. The QoL health and physical functioning domain improved also. Conclusions The development of a structured exercise programme can improve quality of life, physical functioning, PO4 levels and urea clearances of dialysis patients.

Sustaining a hemodialysis exercise program : a review

This article reviews the literature addressing exercise programs for dialysis patients to identify elements necessary for sustaining exercise programs in this population. Literature searches for publications (January 1980–February 2009) in Medline (OVID), PubMed, CINAHL (EBSCO), EBSCOhost EJS, ProQuest Central, Web of Science, Cochrane Library, Google Scholar, ScienceDirect, SpringerLink (Kluwer), and Wiley Interscience (Blackwell) were performed. Reference lists from relevant articles were hand-searched for further publications. Criteria for inclusion included full-text primary research and review articles focused on exercise for adult hemodialysis patients. One hundred and seventy one publications were found with a primary focus on exercise in hemodialysis. Of these, 28 primary research and 14 review articles addressed one or more aspects of sustainability of hemodialysis exercise programs. Factors contributing to sustainable exercise programs included: dedicated exercise professionals; encouragement to exercise intradialytically; dialysis and medical staff commitment; adequate physical requirements of equipment and space; interesting and stimulating; cost implications need to be addressed; exercise is not for everyone; requires individual prescription; and there is no age barrier to exercise on hemodialysis.

A haemodialysis nutritional screening tool for nurses : a pilot study

The purpose of the study was to pilot a nurse-performed nutritional screening tool (NST) for dialysis patients in order to identify nutritionally at-risk patients. Haemodialysis (HD) patients are at risk of nutritional-related problems. Nutritional screening by nurses may assist in the early recognition of and response to these problems. An NST was developed using 9 screening parameters. (BMI, weight change, poor appetite, GI symptoms, albumin, pre-dialysis urea, K+, PO4++, HbA1c). The NST was compared with Standard Dietitian Assessment (SDA). 44 HD patients were screened with the NST and then with SDA. The tool showed sensitivity of 0.7 (95%CI+/- 0.21) and a specificity of 0.77 (95%CI+/-0.16). Reliability was low (alpha = .18). Alpha increased to 0.32 if pre-dialysis urea was removed from the tool and increased to 0.48 if weight loss, appetite, K+ and PO4++ were used alone. The pilot study showed a low reliability of the NST compared with SDA. With further analysis and modifications, the NST has the potential to assist nutritional screening by nurses in dialysis centres that have limited dietetic access.

How a culture of exercise benefits patients on dialysis

It is widely known that patients on dialysis benefit from exercise. Here, Paul Bennett points out that patients can increase the amount and the quality of exercise if the dialysis centre they are attending has a culture of exercise. He describes the elements required to maintain such a culture.

Effect of timing of dialysis commencement on clincial outcomes of patients with planned initiation of peritoneal dialysis in the ideal trial

Background: Since the mid-1990s, early dialysis initiation has dramatically increased in many countries. The Initiating Dialysis Early and Late (IDEAL) study demonstrated that, compared with late initiation, planned early initiation of dialysis was associated with comparable clinical outcomes and increased health care costs. Because residual renal function is a key determinant of outcome and is better preserved with peritoneal dialysis (PD), the present pre-specified subgroup analysis of the IDEAL trial examined the effects of early-compared with late-start dialysis on clinical outcomes in patients whose planned therapy at the time of randomization was PD.

Methods: Adults with an estimated glomerular filtration rate (eGFR) of 10 - 15 mL/min/1.73 m2 who planned to be treated with PD were randomly allocated to commence dialysis at an eGFR of 10 - 14 mL/min/1.73 m2 (early start) or 5 - 7 mL/min/1.73 m2 (late start). The primary outcome was all-cause mortality.

Results: Of the 828 IDEAL trial participants, 466 (56%) planned to commence PD and were randomized to early start (n = 233) or late start (n = 233). The median times from randomization to dialysis initiation were, respectively, 2.03 months [interquartile range (IQR):1.67 - 2.30 months] and 7.83 months (IQR: 5.83 - 8.83 months). Death occurred in 102 early-start patients and 96 late-start patients [hazard ratio: 1.04; 95% confidence interval (CI): 0.79 - 1.37]. No differences in composite cardiovascular events, composite infectious deaths, or dialysis-associated complications were observed between the groups. Peritonitis rates were 0.73 episodes (95% CI: 0.65 - 0.82 episodes) per patient-year in the early-start group and 0.69 episodes (95% CI: 0.61 - 0.78 episodes) per patient-year in the late-start group (incidence rate ratio: 1.19; 95% CI: 0.86 - 1.65; p = 0.29). The proportion of patients planning to commence PD who actually initiated dialysis with PD was higher in the early-start group (80% vs 70%, p = 0.01).

Conclusion: Early initiation of dialysis in patients with stage 5 chronic kidney disease who planned to be treated with PD was associated with clinical outcomes comparable to those seen with late dialysis initiation. Compared with early-start patients, late-start patients who had chosen PD as their planned dialysis modality were less likely to commence on PD.

Factors affecting peritoneal dialysis selection in Taiwanese patients with chronic kidney disease

BACKGROUND: Taiwan has the highest incidence and prevalence of end-stage renal disease (ESRD) in the world with 55,499 ESRD patients on long-term dialysis. Nevertheless, 90.96% of these patients are managed on maintenance haemodialysis (HD), with only 9.03% enrolled in a peritoneal dialysis (PD) programme. AIM: The study aim was to identify the factors affecting Taiwanese patient's selection of PD in preference to HD for chronic kidney disease. METHODS: A cross-sectional research design was utilized with 130 chronic renal failure (CRF) patients purposively selected from outpatient nephrology clinics at four separate Taiwan hospitals. Logistic regression was used to identify the main factors affecting the patient's choice of dialysis type. RESULTS: Single-factor logistic regression found significant differences in opinion related to age, education level, occupation type, disease characteristics, lifestyle modifications, self-care ability, know-how of dialysis modality, security considerations and findings related to the decisions made by medical personnel (P < 0.05). Moreover, multinomial logistic regression after adjustment for interfering variables found that self-care ability and dialysis modality know-how were the two main factors affecting the person's selection of dialysis type. CONCLUSIONS: Self-care ability and the person's knowledge of the different types of dialysis modality and how they function were the major determinants for selection of dialysis type in Taiwan based on the results from this study. The results indicate that the education of CRF patients about the types of dialysis available is essential to enable them to understand the benefits or limitations of both types of dialysis.

A politics of what: the enactment of peritoneal dialysis in indigenous Australians

This paper explores, on the one hand, the requirements of the technologies and practices that have been developed for a particular type of renal patient and health network in Australia. On the other, we examine the cultural and practical specificities entailed in the performance of these technologies and practices in the Indigenous Australian context. The praxiographic orientation of the actor-network approach – which has been called 'the politics of what' (Mol 2002) – enabled us to understand the difficulties involved in translating renal healthcare networks across cultural contexts in Australia; to understand the dynamic and contested nature of these networks; and to suggest possible strategies that make use of the tensions between these two disparate networks in ways that might ensure better healthcare for Indigenous renal patients.

Dialysis residential care : a future dialysis service model

People with chronic kidney disease are ageing and have increasing co-morbidities. The current delivery of renal replacement therapy, dialysis and transplantation, needs to adjust to changing patient needs. This paper proposes a potential future service delivery model featuring a dialysis residential care facility and a care coordination focus. The residential care facility would be composed of four levels of care; high, hostel, independent and outpatient. The paper argues that this model may result in decreased morbidity, improved patient quality of life and may prove cost effective. Patients' nutritional status, medication adherence and transport efficiency may be improved. We propose this model to stimulate further debate in order to meet the needs of current and future chronic kidney disease patients.

Vascular access surveillance : the role of the access nurse in the renal dialysis unit.

Introduction
In January 2006, the Renal Dialysis Unit at Geelong Hospital appointed a Vascular Access Nurse. A Transonic Flow Qc HDO2 Ultrasound Dilution Monitor was purchased to monitor access flow and recirculation in arteriovenous fistulae in an attempt to predict AVF stenoses requiring early surgical correction.

Methods
A bi-monthly monitoring program tested all facility-based patients. 82 patients were assessed for access flow and recirculation between February and December 2006.

Results
18 (22%) had poor AVF function; 13 with access flows <500ml/minute on initial testing and 5 with an access flow decreasing >25% over a four month period. Of the 18 patients shown to have poor access flow, 2 died within one month of measurement while 5 were too frail to attempt corrective surgery. The remaining 11 proceeded to ultrasound or fistulography. A >50% stenosis was detected in all 11 cases. Of these, 4 had successful vein patch surgery and one had PTFE grafting, each with marked improvement in access flow. One had failed vein patch surgery requiring creation of a femoral AVF, one patient required cvc insertion to await AVF creation, and one had failed stenting requiring a permanent cvc. 3 died before planned surgery.

Conclusion
5 of the 82 patients that had access flow assessment, and needed further evaluation, proceeded to successful pre-emptive surgical intervention. We believe the Transonic is a useful adjunct to routine clinical AVF surveillance, in providing early evidence of AVF failure that can be avoided by pre-emptive surgery.

The impact of nurse-led education on haemodialysis patients' phosphate binder medication adherence

Background Phosphate binder medication adherence is required to maintain optimal phosphate levels and minimise bone disease in people with end stage kidney disease.

Objectives To examine the impact of a nurse-led education intervention on bone disorder markers, adherence to phosphate binder medication and medication knowledge.

Design Descriptive study with a paired pre–post intervention survey.

Participants Adults receiving haemodialysis.

Methods Twelve-week intervention where patients self-administered their phosphate binder medication at each dialysis treatment. Nurses provided individualised education. Patients completed a pre- and post-intervention survey designed to explore their knowledge of phosphate binders.

Results There were no statistically significant changes in clinical markers but a significant improvement in the proportion of patients who took their phosphate binder correctly, increasing from 44 to 72% (p = 0.016). There were moderate to large effect size changes for improved knowledge.

Conclusions A nurse-led intervention education programme can increase patients' phosphate binder adherence. However, this does not necessarily manifest into improved serum phosphate levels.

Developing a dialysis centre foot screening culture

Foot lesions are common in the dialysis population and contribute to increased morbidity and mortality (Broersma 2004). lmportantly, patients on dialysis with and without diabetes are at increased risk of foot ulcers (Jones et al. 2012) and lower limb amputation (Kaminski, Frescos & Tucker 2012). Simple foot screening in dialysis centres can identify those at risk of foot complications and the presence of foot ulcers (Ahmad 2009; Ng et al. 2003). Valid and reliable foot screening tools have been developed in the dialysis context to identify those at risk and those with actual ulcers (Murphy et al. 2012).ln 2011, following the completion of a Diabetes and Renal Pilot Study and staff education, Moorabbin Haemodialysis Unit and Southern Health, identified the need to formalise foot screening for all patients and increase the rate at which these were conducted. The aim of this report is to present a summary of the audit evaluation of foot health screens and referrals in our dialysis centre.
