Relationship Between Health Literacy and End-Stage Renal Disease among Type II DiabeticsStolte, Joelle M. 01 January 2018 (has links)
The progression of End Stage Renal Disease (ESRD) among type II diabetics is preventable, yet complications continue to plague many. Reports show that 29.1 million people (9.3%) in the United States have diabetes, and 40% of those individuals develop ESRD. Four research questions explored the relationship between ESRD, health literacy, and healthcare. Data from 2010-2015 from the National Institute of Health (NIH) was quantitatively analyzed. The conceptual framework was the revised health service utilization theory. The target population included 3939 diverse males and females between the ages of 20-75 diagnosed with type II Diabetes. Results from Chi-square, cross-tabulation, binary, and multinomial logistic regression revealed that there is a statistically significant relationship between inadequate health literacy and ESRD (p= <0.05), inadequate health literacy and healthcare services (p= <0.05), and healthcare services and development of ESRD (p=<.001). Findings exposed significant demographic co-factor differences. Males developed ESRD more than females, and African American and Hispanic populations were almost 2 times more likely than Caucasians to develop ESRD. As participants age, odds for developing ESRD increase about 2-3 times. Both race and education were significant predictors of inadequate health literacy. African Americans and Hispanics were 3 times more likely to have inadequate health literacy than Caucasian participants. Lower education increased the odds of having inadequate health literacy approximately 7.6 times. Results show that Caucasian participants had higher education levels and private health insurance, whereas African Americans and Hispanics had lower education and no insurance or Medicaid. Implications from this research show that social determinants among vulnerable populations are impacting an individual's health literacy and ability to adequately manage their health. Evidence from this study generates social change through recognition that health literacy is fundamental when attempting to prevent chronic disease complications and promote positive health.

Chronic Care Model Staff Education and Adherence with End-Stage Renal Disease PatientsAddo, Emilia K. 01 January 2015 (has links)
The management and treatment of chronic diseases, such as end-stage renal disease, is often unproductive because of patients' poor adherence to treatment. The chronic care model toolkit is an Agency for Healthcare Research and Quality supported framework, associated with improved outcomes in patients living with chronic disease. The purpose of this project was to develop and plan an educational program using the chronic care model toolkit for the interdisciplinary clinical staff of a renal hemodialysis center. The goal of this project was to adapt team building between patients and their clinicians through the use of the chronic care model in order to improve patients' adherence to treatment. The educational program materials were developed, including a plan for future implementation over 6 weeks in 2-hour twice-weekly sessions. Program planning accounted for the mixed roles and responsibilities of the interdisciplinary clinical team members, who will share their knowledge among the team and act as patient advisors. The pretest and posttest materials were developed from the toolkit Team Health Audit Questionnaire, which can be used to evaluate staff learning after the program is delivered. Existing clinical metrics are tracked through a Quality Assessment Performance Improvement measure, which will be used to evaluate potential long term influences of the program on patient adherence and outcomes. The project may contribute to social change in practice by enhancing teamwork that has the potential to improve clinical outcomes. Future research should include longitudinal studies on team building using the chronic care model toolkit to determine if its adaption enhances team effort and contributes to a collaborative workforce that improves clinical outcomes.

Renal Ischemia/Reperfusion Injury in Diabetes : Experimental Studies in the RatMelin, Jan January 2002 (has links)
<p>Diabetes mellitus (DM) is one of the leading causes of end stage renal failure. An increased susceptibility to renal ischemia/reperfusion (I/R)-injury was found in DM rats. Unilateral renal ischemia for as short as 20 minutes led to an irreversible progressive injury in DM kidneys, whereas the injury in non-DM kidneys was almost reversible. The renal I/R injury was characterized by anuria, infiltration of inflammatory cells, tubular atrophy, dilation of the remaining tubuli and tubulointerstitial fibrosis. Necrotic areas were found in the inner parts of the outer medulla and in the papilla. The renal medulla was the most vulnerable part of the kidney. This was seen both by the extent of fibrosis four and eight weeks after I/R and by the presence of TUNEL-positive (apoptotic) cells 6h after ischemia. Increased accumulation of HA and enhanced CD44 expression was seen after I/R in DM kidneys.</p><p>Treatment with long acting insulin 7-14 days before I/R, decreased the number of apoptotic cells in the renal medulla and protected renal function and morphology after the insult, while insulin treatment after the injury did not have any protective effect.

Hobson's choice: dialysis or the coffin: a study of dialysis decision-making amongst older peopleFetherstonhaugh, Deirdre Marie Anne Unknown Date (has links) (PDF)
Introduction: Forty years ago the life saving and life prolonging therapy of dialysis was rationed. It was extremely unlikely that people aged over 50 years would be offered treatment. Today, those aged over 65 years are becoming the fastest growing group of patients on dialysis. Changing population demographics and referral patterns, the opening up of eligibility for dialysis to high risk individuals, refinement and developments in dialysis technology and its ‘success’ in keeping more patients alive for longer periods, along with rising public expectation, are just some of the reasons behind this change in the age profile of those being currently treated for kidney failure. Older people are likely to have multiple co-morbidities and decreased functional status that may complicate their decision-making about dialysis and limit their treatment options. / Enhancing choice and involvement in treatment decision-making to the patient’s satisfaction is a central theme of health care ethics. Current national and international ethical guidelines about the initiation of dialysis recommend shared or joint decision-making and discuss patient ‘benefit’ and patient ‘need’. This project sought to determine how these recommendations, and other ethical issues related to informed consent, possible withdrawal of treatment and quality of life, were embodied in the personal experiences of a group of older people facing dialysis decisions. / Aim: The general aim of this research was to follow the dialysis decision-making process over time amongst a group of people aged 65 years and older. More specifically, this research sought to explore with the participants the following issues: what factors impacted on their dialysis decision-making; how they understood both what was happening to them and the goals of treatment; their preferences for information seeking; how they perceived any future decision-making; how or whether the commencement and experience of dialysis influenced their decision-making; and once treatment had been initiated, how they felt about their initial decisions. / Method: A predominantly longitudinal qualitative study was undertaken. Meetings were conducted prior to the potential initiation of dialysis with 21 participants. These meetings involved a semi-structured interview and the administration of three questionnaires focusing on preferences for decision-making, information seeking and quality of life. Data was also collected from the participants’ health records. For those participants who commenced dialysis a further two meetings were undertaken one month and then six months after treatment was instigated. The qualitative data was analysed thematically using concepts that had either been pre-determined and explored within the interviews or, had emerged from the participants’ stories. / Findings: Findings from this study include: participants not feeling that they had a choice about dialysis; a mismatch between theoretical expectations of informed consent and shared decision-making and the ‘actor centred experiential’ model of decision-making adopted by participants; a need to re-evaluate the balance and relationships between physiological measures of effectiveness emphasised by health professionals, and psychosocial and functional markers valued by participants; and treatment goals not being individually negotiated. / Conclusion: An interest in remaining alive was the driving force behind why participants chose to have dialysis. Other factors impacting on decisions about dialysis were multi-faceted and were based on priorities other than what health professionals consider important. Shared decision-making, as described in the literature, is not unproblematic. However, health professionals need to accept the underlying premises on which shared decision-making is based so that they can find out what expectations patients have of treatment, beyond that of saving life. Such expectations need to be discussed with patients and the various treatment options need to be negotiated in an attempt to achieve patients’ goals. Patients should be encouraged however to be involved in decision-making to the extent to which they desire.

Thrombotic risk assessment in end stage renal disease patients on renal replacement therapySharma, Sumeet January 2015 (has links)
End stage renal disease (ESRD) patients have an excess cardiovascular risk, above that predicted by traditional risk factor models. Despite the advances in both Cardiovascular disease (CVD) management and renal replacement therapy (RRT), there still is a major burden of cardiovascular mortality and morbidity in the chronic kidney disease (CKD) population. Declining renal function itself represents a continuum of cardiovascular risk and in those individuals who survive to reach ESRD, the risk of suffering a cardiac event is uncomfortably and unacceptably high. Pro-thrombotic status may contribute to this increased risk. Global thrombotic status assessment, including measurement of occlusion time (OT) the time taken to form an occlusive platelet rich thrombus and thrombolytic status (time taken to lyse such thrombus) as assessed by measuring Lysis Time (LT), may identify vulnerable patients. The aim of this study was to assess overall thrombotic status in ESRD and relate this to cardiovascular and peripheral thrombotic risk. Small sub studies were also planned to establish the effect of RRT modality on the thrombotic status.

Factors associated with the severity of pruritus in patients with terminal chronic kidney disease undergoing hemodialysis in Lima, PeruKossuth-Cabrejos, Stefano, Gavino-Gutiérrez, Arquímedes M., Silva-Caso, Wilmer 01 January 2020 (has links)
The objective of the study is to analyze the factors associated with the severity of pruritus in patients with terminal chronic kidney disease undergoing hemodialysis. The methodology used is based on a cross-sectional study in patients receiving hemodialysis at the Centro Nacional de Salud Renal. Severe pruritus was defined as a score on the visual analogue scale greater than or equal to 7, and the strength of association with the possible risk factors was assessed by calculating prevalence ratios. Regarding the results, 264 patients were included, 59.9% were male, with a mean time on hemodialysis of 10.26 ± 7.14 years. 75% experienced pruritus, of this group, 1 in 3 presented severe pruritus. Hyperphosphatemia and the use of antihistamines were associated with a higher prevalence of severe pruritus (RP 1.71, 95% CI 1.09-267 and RP 2.39, 95% CI 1.51-3.75, respectively). The positive serology for Hepatitis C Virus was described as a protective factor for presenting severe pruritus (RP 0.55, 95% CI 0.33 - 0.89). In conclusion, severe uremic pruritus is a frequent problem in patients with chronic terminal kidney disease who have hyperphosphatemia and treatment with antihistamines independently of the time they have been on hemodialysis. / Revisión por pares

The Economic Burden of End-stage Renal Disease in Canada: Present and Future / Economic Burden of End-Stage Renal Disease in CanadaZelmer, Jennifer 02 1900 (has links)
End-stage renal disease (ESRD), or kidney failure, is a serious illness with significant health consequences and high-cost treatment options. Since the early 1980s, the number of Canadians with ESRD has more than quadrupled (CIHI, 2001), leading to questions about the current and future impact of the disease on public health, quality of life, health spending, and patients’ productivity. Using an economic burden of illness approach, this thesis estimates ESRD’s “direct” health care costs and “indirect” costs, such as productivity losses due to premature death and short- and long-term disability. It also projects future results under various alternative assumptions using a multi-state discrete time Markov model. The analysis suggests that, although less than 0.1% of Canadians have ESRD, it generated direct health care costs of $1.3 billion in 2000 or $51,099 per person with ESRD. That compares to $3,183 per capita for Canadians overall (CIHI, 2002b). Adding indirect morbidity and mortality costs brings the total to $1.9 billion. Rising ESRD numbers suggest higher costs in the future. Further analysis explored the effect of various assumptions about drivers of past trends, such as population growth, changes in the age structure, and the prevalence of conditions known to cause ESRD (e.g. diabetes). Projections were most sensitive to assumptions about the rate at which new cases are diagnosed. If current trends continue, the total economic burden of the disease can be expected to reach $7.9 billion by 2015 (year 2000 dollars). On the other hand, if the rate of new cases in 2000 were maintained, the economic burden of illness would be $5.7 billion in 2015. Nevertheless, under this and many other assumptions, there is likely to be a significant gap between available organs for transplant and the demand for transplantation. The likely effects of various options for addressing this gap are also explored. / Thesis / Doctor of Philosophy (PhD)

NADPH Oxydase et Stress Oxydant au cours de l'Insuffisance Rénale Chronique : modulation par les HDL / NADPH Oxidase and Oxidative Stress during Chronic Kidney Disease : modulation by HDLGoux, Aurélie 13 December 2010 (has links)
Les maladies cardiovasculaires (CV) représentent la première cause de mortalité lors de l'insuffisance rénale chronique (IRC). Cette morbidité apparat précocement lors de l'IRC et ne peut être explique par les facteurs de risque traditionnels. Le stress oxydant (SO), composante du cortège métabolique de l'IRC, représente un facteur de risque non traditionnel intriqué avec l'inflammation et la malnutrition. Le but de ce travail a été d'étudier la place du SO dans la survenue des complications CV au cours de l'IRC sur modale animal, puis de comparer le profil protéomique et la fonctionnalité des HDL in vitro entre sujets hémodialysés (HD) et témoins. Le SO au niveau CV a été étudié dans un modèle animal (adénine) d'IRC associé à la malnutrition. L'activité de la NADPH oxydase cardiaque est triple, alors que les activités des complexes de la chaîne respiratoire mitochondriale et de la SOD sont normales. Cette surproduction d'anion super oxyde est associé à une surexpression de l'ostéopontine et du pro-collagène de type I. L'étude protéomique des HDL de sujets HD et témoins a permis de préciser les anomalies qualitatives associées à la baisse des HDL induite par l'IRC. Les propriétés anti-oxydantes des HDL de ces mêmes sujets ont été étudiées in vitro sur un modèle d'oxydation des LDL au cuivre et sur un modèle cellulaire d'activation de la NADPH oxydase. En comparaison aux témoins, les HDL des sujets HD perdent leur capacité de protection des LDL contre l'oxydation. Par contre, la modulation de la NADPH oxydase sur modèle cellulaire est conservée avec les HDL de sujets HD mais serait moindre en présence d'une forte inflammation systémique. Ces résultats suggèrent que le SO est au cœur des complications cardiaques au cours de l'IRC. Parmi les mécanismes de défense endogènes, les propriétés anti-oxydantes des HDL sont en partie altérées chez le sujet HD. / Cardiovascular (CV) diseases are the first cause of mortality during chronic kidney disease (CKD) and cannot only be explained by traditional risk factors (age, gender, dyslipidemia, hypertension). Oxidative stress, which has been associated with CKD, appears as a non-traditional risk factor closely interconnected with inflammation and malnutrition.This study aimed at investigating oxidative stress in CV complications in uremic rats. Then, HDL proteomic profile and in vitro functionality of HDL were compared between hemodialyzed (HD) patients and control subjects.First, an animal model of CKD associated with malnutrition, the adenine-fed rats, was set up in order to study CV oxidative stress. NADPH oxidase activity was increased three-fold, but the maximal activity of mitochondrial respiratory chain complexes and SOD were not different between groups. Superoxide anion output was associated with accumulation of osteopontin and of pro-collagen type I. In a second part, HDL proteomic study from HD and control subjects was performed to characterize qualitative modifications associated with the decrease in HDL observed in CKD. HDL anti-oxidative activities from these subjects were studied in vitro in a model of copper-induced LDL oxidation and in a cellular model of NADPH oxidase activation. Compared to control, HDL from HD patients failed to protect LDL oxidation. By contrast, HDL modulation of NADPH activity is maintained in HD patients but could be impaired by elevated inflammation.These results suggest that oxidative stress is a key event in cardiac complications during CKD. Among protective endogenous mechanisms, HDL anti-oxidative properties could be impaired in HD patients.
