Barriers to kidney transplants in Indonesia : a literature review

Background: People living with chronic kidney disease will require renal dialysis or a kidney transplant to maintain life. Although Indonesia has a developing healthcare industry, Indonesia's kidney transplant rates are lower than comparable nations.

Purpose: To explore the healthcare literature to identify barriers to kidney transplants in particular in relation to Indonesia.

Methods: Healthcare databases were searched (CINAHL, Medline, EBSCOhostEJS, Blackwell Synergy, Web of Science, PubMed, Google Scholar and Proquest 5000) using the search terms: transplant, kidney disease, renal, dialysis, haemodialysis, Indonesia and nursing. The search was limited to English and Indonesian language data sources from 1997 to 2007. Reference lists of salient academic articles were hand searched.

Results: The results of our search identified six articles that met our criteria. Costs are the major barrier to kidney transplant in Indonesia, followed by cultural beliefs, perception of the law, lack of information and lack of infrastructure. In addition, kidney disease prevention strategies are required.

Conclusions: There are many complex socio-economic, geographical, legal, cultural and religious factors that contribute to low kidney transplant rates in Indonesia. Although an increase in transplantation rates will require strategies from various agencies, healthcare professionals, including nurses, can play a role in overcoming some barriers. Community education programmes, improving their own education levels and by increasing empowerment in nursing we may contribute to improved kidney transplant rates in Indonesia.

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.

Being a parent on dialysis : a literature review

Aim
This literature review explored the extant literature to further our understanding of the experience of being a parent on dialysis.
Methods
Keywords used to search the literature were haemodialysis, hemodialysis, chronic kidney disease, end stage renal disease, parent and experience. Databases searched included CINAHL, Medline, Wiley/Blackwell, EBSCOHost, Web of Science, Pubmed, and ProQuest. Years included were 1999 to 2009. Seventeen primary research articles (sixteen qualitative, one mixed methods) met the search criteria with only one on parents undergoing dialysis.
Findings
The experience of the parent on dialysis has rarely been explored in the literature. Related research has indicated important themes including: restricted lives; relationships; adjustment; consequences and future outlook.
Conclusions
More should be known about challenges that face parents who receive dialysis. This review established an urgent need for further research to determine the experiences and needs of this population to provide empirical, person-centred nursing care.

Antimicrobial, antioxidant and anti-inflammatory phenolic activities in extra virgin olive oil

The Mediterranean diet is associated with a lower incidence of chronic degenerative diseases and higher life expectancy. These health benefits have been partially attributed to the dietary consumption of extra virgin olive oil (EVOO) by Mediterranean populations, and more specifically the phenolic compounds naturally present in EVOO. Studies involving humans and animals (in vivo and in vitro) have demonstrated that olive oil phenolic compounds have potentially beneficial biological effects resulting from their antimicrobial, antioxidant and anti-inflammatory activities. This paper summarizes current knowledge on the biological activities of specific olive oil phenolic compounds together with information on their concentration in EVOO, bioavailability and stability over time.

The effect of cocoa supplementation on hepatic steatosis, reactive oxygen species and LFABP in a rat model of NASH

Background: Non alcoholic steatohepatitis is hypothesised to develop via a mechanism involving fat accumulation and oxidative stress. The current study aimed to investigate if an increase in oxidative stress was associated with changes in the expression of liver fatty acid binding protein in a rat model of non alcoholic steatohepatitis and whether cocoa supplementation attenuated those changes.

Methods: Female Sprague Dawley rats were fed a high fat control diet, a high fat methionine choline deficient diet, or one of four 12.5% cocoa supplementation regimes in combination with the high fat methionine choline deficient diet.

Results: Liver fatty acid binding protein mRNA and protein levels were reduced in the liver of animals with fatty liver disease when compared to controls. Increased hepatic fat content was accompanied by higher levels of oxidative stress in animals with fatty liver disease when compared to controls. An inverse association was found between the levels of hepatic liver fatty acid binding protein and the level of hepatic oxidative stress in fatty liver disease. Elevated NADPH oxidase protein levels were detected in the liver of animals with increased severity in inflammation and fibrosis. Cocoa supplementation was associated with partial attenuation of these pathological changes, although the severity of liver disease induced by the methionine choline deficient diet prevented complete reversal of any disease associated changes. Red blood cell glutathione was increased by cocoa supplementation, whereas liver glutathione was reduced by cocoa compared to methionine choline deficient diet fed animals.

Conclusion: These findings suggest a potential role for liver fatty acid binding protein and NADPH oxidase in the development of non alcoholic steatohepatitis. Furthermore, cocoa supplementation may have be of therapeutic benefit in less sever forms of NASH.

Is point of care testing for anaemia (HB) and microalbumin feasible in people with type 2 diabetes attending diabetes outpatient clinics?

Introduction: Diabetes is the major cause of chronic kidney disease (CKD) in Australia. Anaemia of CKD occurs earlier than in non-diabetics and is often insidious and undetected.

Aim: A large, prospective, single-centre study was undertaken to determine the feasibility of point of care testing (POCT) haemoglobin (Hb) and microalbumin in people with type 2 diabetes (T2DM) attending routine outpatient clinic appointments (OPC).

Method: Clinic nurses measured Hb and microalbumin using the HemoCue Haemoglobin Capillary Analyser and the HemoCue Urine Albumin Analyser (Medipac Scientific), respectively when they tested blood glucose, weight and blood pressure. The nurses were trained to use the analysers before the study commenced. Standard demographic data, duration of diabetes, treatment mode, and presence of complications, comorbidities, and HbA1c were ascertained from patients’ medical records.

Results: Five hundred and fifty-four (80%) patients were screened. The nurses were able to perform the tests competently but testing, especially microalbumin, was time-consuming. Patients’ mean age was 62 years (11 SD): 230 females, mean blood glucose (BG) 10 (3.9 SD) mmol/L, mean haemoglobin 127.2 (16.3 SD) g/L; mean microalbumin 47.8 (58.7 SD) mg/L: 324 were males, mean BG 10.2 (3.9 SD) mmol/L, mean Hb 138.6 (18.8 SD) gm/L, and mean microalbumin 67.9 (73.9 SD) mg/L. 27% of males and 22% of females were anaemic. Of those with anaemia, 27% of females and 29% of males had microalbuminuria.

Conclusions: POCT is feasible in routine outpatient clinics but is time-consuming. One in four T2DM attending OPC were anaemic. POCT Hb testing in OPC is feasible and could identify T2DM who need full haematological assessment.

An Intelligent Human-Computer Interaction System for Decision Support

This paper proposes a novel architecture for
developing decision support systems. Unlike conventional decision support systems, the proposed architecture endeavors to reveal the decision-making process such that humans' subjectivity can be
incorporated into a computerized system and, at the same time, to
preserve the capability of the computerized system in processing information objectively. A number of techniques used in developing the decision support system are elaborated to make the decisionmarking
process transparent. These include procedures for high dimensional data visualization, pattern classification, prediction, and evolutionary computational search. An artificial data set is first
employed to compare the proposed approach with other methods. A simulated handwritten data set and a real data set on liver disease diagnosis are then employed to evaluate the efficacy of the proposed
approach. The results are analyzed and discussed. The potentials of the proposed architecture as a useful decision support system are demonstrated.

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.

Estimating individual glomerular volume in the human kidney : clinical perspectives

Background. Measurement of individual glomerular volumes (IGV) has allowed the identification of drivers of glomerular hypertrophy in subjects without overt renal pathology. This study aims to highlight the relevance of IGV measurements with possible clinical implications and determine how many profiles must be measured in order to achieve stable size distribution estimates.

Methods. We re-analysed 2250 IGV estimates obtained using the disector/Cavalieri method in 41 African and 34 Caucasian Americans. Pooled IGV analysis of mean and variance was conducted. Monte-Carlo (Jackknife) simulations determined the effect of the number of sampled glomeruli on mean IGV. Lin’s concordance coefficient (RC), coefficient of variation (CV) and coefficient of error (CE) measured reliability.

Results. IGV mean and variance increased with overweight and hypertensive status. Superficial glomeruli were significantly smaller than juxtamedullary glomeruli in all subjects (P < 0.01), by race (P < 0.05) and in obese individuals (P < 0.01). Subjects with multiple chronic kidney disease (CKD) comorbidities showed significant increases in IGV mean and variability. Overall, mean IGV was particularly reliable with nine or more sampled glomeruli (RC > 0.95, <5% difference in CV and CE). These observations were not affected by a reduced sample size and did not disrupt the inverse linear correlation between mean IGV and estimated total glomerular number.

Conclusions. Multiple comorbidities for CKD are associated with increased IGV mean and variance within subjects, including overweight, obesity and hypertension. Zonal selection and the number of sampled glomeruli do not represent drawbacks for future longitudinal biopsy-based studies of glomerular size and distribution.

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.

Serum 25-hydroxyvitamin D deficiency and the 5-year incidence of CKD

Low serum 25-hydroxyvitamin D (25[OH]D) levels have been associated with chronic kidney disease in cross-sectional studies. However, this association has not been studied prospectively in a large general population–based cohort.

This prospective cohort study shows that vitamin D deficiency is associated with a higher annual incidence of albuminuria and reduced eGFR and independently predicts the 5-year incidence of albuminuria. These associations warrant further exploration in long-term prospective clinical trials.

How do Thai patients receiving haemodialysis cope with pain?

Medicine non-adherence in kidney transplantation

Background: The increasing prevalence of chronic kidney disease, the relative shortage of kidney donors and the economic- and health-related costs of kidney transplant rejection make the prevention of adverse outcomes following transplantation a healthcare imperative. Although strict adherence to immunosuppressant medicine regimens is key to preventing kidney rejection, evidence suggests that adherence is sub-optimal. Strategies need to be developed to help recipients of kidney transplants adhere to their prescribed medicines. Findings: This review has found that a number of factors contribute to poor adherence, for example, attitudes towards medicine taking and forgetfulness. Few investigations have been conducted, however, on strategies to enhance medicine adherence in kidney transplant recipients. Strategies that may improve adherence include pharmacist-led interventions (incorporating counselling, medicine reviews and nephrologist liaison) and nurse-led interventions (involving collaboratively working with recipients to understand their routines and offering solutions to improve adherence). Strategies that have shown to have limited effectiveness include supplying medicines free of charge and providing feedback on a participant's medicine adherence without any educational or behavioural interventions. Conclusion: Transplantation is the preferred treatment option for people with end-stage kidney disease. Medicine non-adherence in kidney transplantation increases the risk of rejection, kidney loss and costly treatments. Interventions are needed to help the transplant recipient take all their medicines as prescribed to improve general well-being, medicine safety and reduce healthcare costs. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Exploring motivation and confidence in taking prescribed medicines in coexisting diseases: a qualitative study

Aims and objectives: To explore the motivation and confidence of people with coexisting diabetes, chronic kidney disease (CKD) and hypertension to take their medicines as prescribed. Background: These comorbidities are major contributors to disease burden globally. Self-management of individuals with these coexisting diseases is much more complicated than that of those with single diseases and is critical for improved health outcomes. Design: Motivational interviewing telephone calls were made with participants with coexisting diabetes, CKD and hypertension. Methods: Patients aged ≥18 years with diabetes, CKD and systolic hypertension were recruited from outpatient clinics of an Australian metropolitan hospital between 2008-2009. An average of four motivational interviewing telephone calls was made with participants (n = 39) in the intervention arm of a randomised controlled trial. Data were thematically analysed using the modified Health Belief Model as a framework. Results: Participants' motivation and confidence in taking prescribed medicines was thwarted by complex medicine regimens and medical conditions. Participants wanted control over their health and developed various strategies to confront threats to health. The perceived barriers of taking recommended health action outweighed the benefits of taking medicines as prescribed and were primarily related to copious amounts of medicines. Conclusion: Taking multiple prescribed medicines in coexisting diabetes, CKD and hypertension is a perpetual vocation with major psychosocial effects. Participants were overwhelmed by the number of medicines that they were required to take. The quest for personal control of health, fear of the future and the role of stress and gender in chronic disease management have been highlighted. Participants require supportive emotional interventions to self-manage their multiple medicines on a daily basis. Relevance to clinical practice: Reducing the complexity of medicine regimens in coexisting diseases is paramount. Individualised psychosocial approaches that address the emotional needs of patients with regular follow-up and feedback are necessary for optimal chronic disease self-management. © 2013 John Wiley & Sons Ltd.
