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.

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.

Being dialysis-dependant: a qualitative perspective

The technology of renal dialysis offers a way in which life can be sustained, so it is not surprising that the complex, diverse and evolving iatrogenic aspects of dialysis-dependency continue to be researched. However, there has been a tendency to take for granted the human process of making sense of the intrusiveness of dialysis. This study was designed to explore the meanings of dialysis-dependency. The study sample was 10 participants: five female, five male; five on peritoneal dialysis, five on haemodialysis; whose ages ranged from 22 to 68 years. Using a narrative methodology the following methods were used: in-depth interviews, narrative and thematic analysis, fieldwork/notes from five renal units, participant validation, and journal reflections. A thematic analysis revealed the continuum themes of Freedom-Restrictions, Being Normal-Being Visible, Control-Acquiesce, Hope-Despair and Support-Abandon. The themes portrayed as continuums serve to remind health care professionals that those with chronic illnesses strive to make sense of what is happening to them. Variations within each of these themes can occur daily, weekly or monthly. Acceptance may never be reached or may be tentative. Some clients will strive for control and freedom to choose for themselves, others will acquiesce to the overwhelming changes wrought in their lives. Thus, health care professionals might consider placing the personal meanings of those who are dialysis-dependent to the fore, being sensitive to the sufferings wrought by the regime, which treats but does not cure, which sustains life but does not heal.

Dialysis-dependency: the reformulated or remnant person

Being dependent on dialysis is a potentially overwhelming experience where life as previously known is permanently altered. A dialysis-dependent individual may reformulate their identify or perceive that they are a remnant if their former self. This paper will explore and expand Morse and Penrod's (1999) model as a useful way to understand how a person might reconstruct their identify. Grounded in a narrative methodology, interviews if those on haemodialysis and peritoneal dialysis were thematically analysed. It was found that dialysis dependency brings an acknowledgment if a lost past, an inescapable present and an unknowable future, filtered through hope and despair. Nurses need to understand the suffering, wrought by such a struggle,to facilitate the positive re-envisioning if those who are dialysis dependent.

The Renal Treatment Satisfaction Questionnaire (RTSQ): a measure of satisfaction with treatment for chronic kidney failure.

BACKGROUND: Quality and effectiveness of care can be enhanced through the use of condition-specific measures of satisfaction with treatment. The aim of the present study was to design and develop a measure of satisfaction with treatment for patients with chronic kidney failure (CKF) for use in routine clinical care and clinical trials. The Renal Treatment Satisfaction Questionnaire (RTSQ) was designed to be suitable for people using any of the various treatment modalities for CKF. Items measure satisfaction with aspects of treatment, including convenience, flexibility, freedom, and satisfaction to continue with present form of treatment.

METHODS: A 12-item RTSQ was investigated at a UK hospital-based renal unit, using data from 140 outpatients undergoing renal replacement therapy (hemodialysis, n = 35; continuous ambulatory peritoneal dialysis, n = 57; transplantation, n = 46).

RESULTS: An 11-item scale was developed from the original 12-item version, with a single factor accounting for 59% of the variance and item loadings greater than 0.58. Scale reliability was excellent (alpha = 0.93) in the full sample and proved robust to analysis in separate treatment subgroups. As expected, RTSQ scores differed significantly ( P < 0.0001) between the transplantation and other treatment groups. Those who had received a transplant expressed greater overall satisfaction, with specific advantages of transplantation shown by all individual items, including convenience, time, lifestyle, freedom, and satisfaction to continue current treatment.

CONCLUSION: The RTSQ provides a brief reliable measure of satisfaction with treatment for patients with CKF that is suitable for use in routine clinical care and clinical trials.

Improving renal patient care without compromising safety: interactive simulated e-learning

The nephrology educators network [NEN] recognised in 2007 that inequities existed in the access and delivery of evidence based renal education programs particularly to nurses in regional and remote areas. To address this, a web-based approach to learning, through the development of peer reviewed, interactive nephrology e-learning programs was adopted. These programs aligned with the tenets of e-learning instructional design and afforded more effective and consistent clinical support and induction for nurses in the renal specialty. The e-learning programs promote a standardised evidence-based approach to nephrology education and were developed by content experts from across Australia and New Zealand. The design methodology avoided the duplication of resources while also encouraging knowledge transfer between participating health organisations.

This paper will discuss the development and successful implementation of these e-learning programs across renal healthcare units in Australasia. Implemented packages include: Introduction to Buttonhole Cannulation – featuring an interactive ultrasound and cannulation application; Introduction to Haemodialysis; Introduction to Peritoneal Dialysis [PD], featuring simulated PD machines, allowing for the teaching of troubleshooting without compromising patient safety. E-learning programs are further supported through interactive case scenarios that present unfolding real world simulations and enable learners to meet different patients and manage their care while learning about key messages relating to renal health. Modules currently in development include; Acute Kidney Injury; Fluid Assessment, Water Quality and Vascular Access. The implementation of these programs assist the facilitation of positive change in teaching and learning practices in nephrology nursing aimed at improving patient outcomes.

Typical and atypical haemolytic uraemic syndrome: A brief case comparison report for nurses

Background: Haemolytic uraemic syndrome (HUS) is one of the main causes of acute kidney injury in children. It is a multifaceted disease, characterised by microangiopathic haemolytic anaemia and thrombocytopaenia. It can often affect multiple organ systems, including the central nervous and renal systems.

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.

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.

Sustained low-efficiency dialysis with filtration (SLEDD-f) in the management of acute sodium valproate intoxication

Hemodialysis is only infrequently used in drug overdosage situations. The efficacy of hemodialysis to remove the drug depends upon the pharmacokinetics and pharmacodynamics of the drug. At normal therapeutic concentrations, valproic acid is predominantly protein bound and therefore removal by hemodialysis is limited. In an overdose situation, protein binding is rapidly saturated and therefore the substantially larger quantities of the free drug can rapidly cause toxicity. Slow low-efficient daily diafiltration (SLEDD) has not previously been utilized in a drug overdose situation. We report the effective use of SLEDD to remove high toxic concentrations of valproic acid in an overdose situation. Slow low-efficient daily diafiltration also prevented the rebound phenomenon that can occur as the excess drug is released from its protein-bound stores. Hybrid dialysis therapies deserve further evaluation in the management of other poisonings where extra-corporeal therapy is indicated.

Benign recurrent intrahepatic cholestasis with secondary renal impairment treated with extracorporeal albumin dialysis

Benign recurrent intrahepatic cholestasis (BRIC) is a rare autosomal recessive condition characterized by intermittent episodes of pruritis and jaundice that may last days to months. Treatment is often ineffective and symptoms, particularly pruritis, can be severe. Extracorporeal albumin dialysis (molecular adsorbent recycling system, MARS) is a novel treatment which removes albumin bound toxins including bilirubin and bile salts. We describe a case of a 34-year-old man with BRIC and secondary renal impairment who, having failed standard medical therapy, was treated with MARS. The treatment immediately improved his symptoms, renal and liver function tests and appeared to terminate the episode of cholestasis. We conclude that MARS is a safe and effective treatment for BRIC with associated renal impairment.
