Quality nephrology nursing care : beyond Kt/V

Ask nephrology nurses about the care in their hemodialysis units and they will probably say that high quality care is provided. This perception may reflect a genuine pride in their own and their colleagues' hemodialysis services, however, the meaning of high quality dialysis care remains unclear. Quality is often framed in terms of the high percentage of patients receiving a Kt/V of greater than 1.2 or 1.4. The unfortunate inference here is that high quality hemodialysis care is defined as the waste clearing service of the urea molecule. Defining quality in this narrow way conflicts with the caring and compassionate nursing ethic. Furthermore, it places a high value on a single mathematically derived formula that ignores many other indicators of quality dialysis care. In this article, the authors examine some historical, political, and technical features of Kt/V and use the metaphor of a hangover to illustrate the overuse of Kt/V, arguing that nurses have embraced Kt/V at the expense of other core elements of dialysis nursing care.

Intradialytic hypotension prevention and management knowledge and practices: Results from a survey of Australian and New Zealand nephrology nurses

Intradialytic hypotension (IDH) remains the most frequent serious side effect of hemodialysis, increasing morbidity in patients on hemodialysis. Nephrology nurses have a critical role in the prevention and management of IDH. The aim of this study was to investigate nephrology nurse knowledge and practice habits in the prevention and management of IDH. This was an explorative cross-sectional design, web-based survey of Australian and New Zealand nephrology nurses (n = 173). IDH definitions, blood pressureinterpretation, and IDH interventions were inconsistent and not always evidencebased.Demographic characteristics had little impact on the variation in responses. A universal definition for IDH may improve early recognition of the problem. Formal guidelines in considering individualized interventional strategies for asymptomaticepisodes prior symptomatic IDH occurrence may improve outcomes for patients on hemodialysis

Advance care planning in nephrology care

On completion of this continuing professional development (CPD) activity, participants will be able to:
• describe advanced care planning and its relationship to person-centred care
• identify who is responsible for initiating advance care planning discussions in their nephrology department
• identify the benefits of advanced care planning• recall conversation triggers for raising the topic of advanced care planning.

Nephrology nursing publications : topics and research methods

Four peer-reviewed nephrology nursing society journal publications from 2010 to 2015 were analysed. Journal articles (n=638) were categorised into type, treatment cohort, specific topic and research methods. Primary research (40%) were the most frequent types of publications, followed by systematic reviews (25%) and case studies (16%). Publication patient cohorts were dominated by haemodialysis (41%), followed by chronic kidney disease (15%), kidney transplantation (14%), peritoneal dialysis (12%) and end-of-life care (9%). The most frequent specific topics were vascular access (56 publications), nutrition (35), patient self-management (31), medications (26) and patient quality of life (24). The case study was the most popular method of publishing clinical experience, while cross-sectional survey was the most published research method, followed by qualitative research approaches. There were a low number of publications addressing cost and new therapies.

Attitudes of nephrology nurses toward patient exercise during hemodialysis

Exercise programs are rare in hemodialysis clinics. The study goals were to 1) explorenephrology nurses’ attitudes toward exercise; 2) compare the attitudes between nephrologynurses who had been exposed and those who had not been exposed to an patient exerciseprogram; and 3) measure the psychometric properties of a survey tool to measurenephrology nurses’ attitudes toward intradialytic exercise. Nephrology nurse attitudeswere positive toward patients’ exercising; however, they did not believe it was theirresponsibility to conduct the exercise program. Nephrology nurses who had not seenpatients exercising during dialysis were more likely to perceive exercise barriers. Thisstudy developed a valid and clinically useful 16-item instrument to measure nephrologynurses’ attitudes about patient exercise in four areas: patient benefits, patient barriers,nurse barriers, and health professional enablers.

Initiation into a dialysis-dependent life: an examination of rites of passage

Martin-McDonald et al explore the conceptual and empirical application of the rites of passage model in contemporary health care for those who are dialysis dependent. The findings illustrate the three stages of rites of passage, separation. liminality, and reincorporation. A commentary and response are provided.

Peridontal disease : the overlooked diabetes complication

Periodontal diseases are infectious processes that occur in the presence of bacteria, which trigger an inflammatory response. Periodontal disease is associated with many medical conditions, including diabetes mellitus and its complications (such as kidney disease). It has been described as the "sixth diabetes complication" but is often overlooked in routine diabetes management and complication screening processes. Proactive, preventative dental and diabetes self care, as well as regular dental and diabetes assessment, are important management strategies because periodontal disease contributes to the progression of impaired glucose tolerance to diabetes mellitus and to hyperglycemia in individuals with established diabetes.

Prevalence of kidney damage in Australian adults - the AusDiab Kidney Study

The incidence of ESRD is increasing dramatically. Progression to end-stage may be halted or slowed when kidney damage is detected at an early stage. Kidney damage is frequently asymptomatic but is indicated by the presence of proteinuria, hematuria, or reduced GFR. Population-based studies relating to the prevalence of kidney damage in the community are limited, particularly outside of the United States. Therefore, the prevalence of proteinuria, hematuria, and reduced GFR in the Australian adult population was determined using a cross-sectional study of 11,247 noninstitutionalized Australians aged 25 yr or over, randomly selected using a stratified, cluster method. Subjects were interviewed and tested for proteinuria—spot urine protein to creatinine ratio (abnormal: >=0.20 mg/mg); hematuria—spot urine dipstick (abnormal: 1+ or greater) confirmed by urine microscopy (abnormal: >10,000 red blood cells per milliliter) or dipstick (abnormal: 1+ or greater) on midstream urine sample; and reduced GFR—Cockcroft-Gault estimated GFR (abnormal: <60 ml/min per 1.73 m2). The associations between age, gender, diabetes mellitus, and hypertension, and indicators of kidney damage were examined. Proteinuria was detected in 2.4% of cases (95% CI: 1.6%, 3.1%), hematuria in 4.6% (95% CI: 3.8%, 5.4%), and reduced GFR in 11.2% (95% CI: 8.6%, 13.8%). Approximately 16% had at least one indicator of kidney damage. Age, diabetes mellitus, and hypertension were independently associated with proteinuria; age, gender, and hypertension with hematuria; and age, gender, and hypertension with reduced GFR. Approximately 16% of the Australian adult population has either proteinuria, hematuria, and/or reduced GFR, indicating the presence of kidney damage. Identifying and targeting this section of the population may provide a means to reduce the burden of ESRD.

Impaired K+ regulation contributes to exercise limitation in end-stage renal failure

Background

Patients with end-stage renal failure (ESRF) exhibit grossly impaired maximal exercise performance. This study investigated whether K+ regulation during exercise is impaired in ESRF and whether this is related to reduced exercise performance.

Methods

Nine stable hemodialysis patients and eight controls (CON) performed incremental cycling exercise to volitional fatigue, with measurement of peak oxygen consumption (VdotO2 peak). Arterial blood was sampled during and following exercise and analyzed for plasma [K+] (PK).

Results

The VdotO2 peak was approximately 44% less in ESRF than in CON (P < 0.001), whereas peak exercise PK was greater (7.23 plusminus 0.38 vs. 6.23 plusminus 0.14 mmol dot L-1, respectively, P < 0.001). In ESRF, the rate of rise in PK during exercise was twofold greater (0.43 plusminus 0.05 vs. 0.23 plusminus 0.03 mmol dot L-1dotmin-1, P < 0.005) and the ratio of rise in PK relative to work performed was 3.7-fold higher (90.1 plusminus 13.5 vs. 24.7 plusminus 3.3 nmol dot L-1dot J-1, P < 0.001). A strong inverse relationship was found between VdotO2 peak and the DeltaPKdot work-1 ratio (r = -0.80, N = 17, P < 0.001).

Conclusions

Patients with ESRF exhibit grossly impaired extrarenal K+ regulation during exercise, demonstrated by an excessive rise in PK relative to work performed. We further show that K+ regulation during exercise was correlated with aerobic exercise performance. These results suggest that disturbed K+ regulation in ESRF contributes to early muscle fatigue during exercise, thus causing reduced exercise performance.

Proof of Concept : developing a peer reviewed evidence-based interactive e-learning programme

Knowledge and skill acquisition related to vascular access are traditionally individual institutional educational initiatives. Australia currently has no national evidence based education programme for renal nurses. A survey of Australian and New Zealand Nephrology Educators' conducted in 2009, identified the need for more effective and consistent delivery of clinical education for nurses using innovative, web-based approaches supporting the tenets of e-learning methodologies. This paper discusses the development, implementation and proposed evaluation of a peer reviewed Australasian e-learning programme on buttonhole cannulation. It will further highlight the benefits of inter-organisational partnerships and how these partnerships can facilitate positive change in teaching and learning practices. This project has unique characteristics that collectively provide value, distinction and innovation to nurses, patients and renal departments. As the e-learning programme was founded on a platform of evidence-based practice it is therefore easily transferable to an international context.

Using e-learning to increase the preparedness and confidence of nurses to perform buttonhole cannulation

Arteriovenous fistulae are considered the gold standard for haemodialysis vascular access. Their use can be fraught with complications for both the patient and cannulator, with knowledge, expertise and skills being key factors in reducing access associated morbidity. There is mounting evidence demonstrating the efficacy of the buttonhole technique. One disturbing problem noted with the buttonhole experience has been an increased rate in site infections, anecdotally attributed to poor buttonhole site preparation. Enhanced knowledge and skills for nurses are crucial in increasing patient comfort and improving outcomes.

Although knowledge and skill acquisition related to vascular access are often the focus of individual institutional educational initiatives, a national evidence based program that provides free equitable access to all nurses does not exist in Australasia. A survey of Australasian Nephrology Educators’ identified the need for more effective and consistent delivery of clinical education for nurses using innovative, web‐based approaches that support the tenets of e-learning methodologies. This paper will discuss the development and implementation of an e-learning program for buttonhole cannulation. The preparedness of participants to professionally engage with buttonhole cannulation and their self-efficacy (estimates) in undertaking learning about the clinical procedure using e-learning will be evaluated. In addition it will highlight the benefits of inter‐organizational partnerships and how they can facilitate positive change in teaching and learning practices aimed at improving patient outcomes. This project has unique characteristics that collectively provide value, distinction and innovation to patients, nurses, and renal departments across Australasia. As the e-learning program is founded on evidence based practice this project is easily transferable to an international context.

Exercise during hemodialysis : the intradialytic zumba gold

People requiring dialysis have a lower exercise capacity than the non-ESRD population. Lower exercise capacity is associated with deconditioning, which leads to a reduced quality of life and increased risk of injury. Low-impact exercise programs during dialysis have been found to be safe and beneficial for this group. In addition, intradialytic exercise can alleviate the boredom of receiving dialysis, creating an exercise-focused positive environment in the dialysis center. Increased physical activity may influence people's physical function and confidence, which may further encourage patient empowerment.

Home hemodialysis : a successful option for obese and bariatric people with end-stage kidney disease

The increasing prevalence of obesity in developed countries is reflected in the chronic kidney disease, dialysis, and transplant populations. The added risk factor of obesity increases the risk of vascular events, inflammation, insulin resistance, blood pressure, dyslipidemia, and mortality risk. Nephrology center policies may exclude obese people from transplantation programs resulting in many years of dialysis. The case of a 215-kg Australian male who has successfully dialyzed at home for more than 8 years will be used to illustrate the important considerations and clinical support that these people require for successful home dialysis treatment. The aim of this paper is to report on a program that has successfully trained 23 obese (body mass index >30) people who commenced on home hemodialysis between 2001 and 2009. Body weight ranged between 94.0 and 215 kg (mean 126, SD 26.19) and body mass index ranged between 34.9 and 71 (mean 43.38, SD 9.99) at the start of home training. During the 8.5 years of follow-up, average time on home dialysis was 43.7 months. Home hemodialysis is a feasible treatment for obese people to facilitate longer and more frequent dialysis, resulting in improved hemodynamic stability and improved quality of life. For obese people with end-stage kidney disease, home hemodialysis has shown to be cost-effective and can result in greater treatment efficacy than in-center hospital dialysis.
