Association of education level with dialysis outcome

A Comprehensive Analysis of Litigation in Organ Transplantation for Allegations of Insufficient Policy Coverage, Discrimination and Malpractice

Introduction: Transplantation is a field with unique medical and administrative challenges that involve an equally diverse array of stakeholders. Expectantly, the litigation stemming from this field should be similarly nuanced. There is a paucity of comprehensive reviews characterizing this medicolegal landscape. Design: The Caselaw Access Project Database was used to collect official court briefs of 2053 lawsuits related to kidney, liver, heart, lung, and pancreas transplantation. A thematic analysis was undertaken to characterize grounds for litigation, defendant type, and outcomes. Cases were grouped into policy, discrimination, poor or unsuccessful outcome, or other categories. Results: One hundred sixty-four court cases were included for analysis. Cases involving disputes over policy coverage were the most common across all organ types (N = 55, 33.5%). This was followed by poor outcomes (N = 51, 31.1%), allegations of discrimination against prison systems and employers (N = 37, 22.6%) and other (N = 21, 12.8%). Defendants involved in discrimination trials won with the greatest frequency (N = 29, 90.62%). Defendants implicated in policy suits won 65.3% (N = 32), poor outcomes 62.2% (N = 28), and other 70% (N = 14). Of the 51 cases involving poor outcomes, plaintiffs indicated lack of informed consent in 23 (45.1%). Conclusion: Reconsidering the informed consent process may be a viable means of mitigating future legal action. Most discrimination suits favoring defendants suggested previous concerns of structural injustices in transplantation may not be founded. The prevalence of policy-related cases could be an indication of financial burden on patients. Future work and advocacy will need to substantiate these concerns and address change where legal recourse falls short.

Educational level and gender are associated with emotional well-being in a cohort of Dutch dialysis patients

BACKGROUND

Patients undergoing dialysis have an impaired health-related quality of life (HRQOL). There are conflicting data from small series on whether patient-related factors such as educational level have an impact on experienced HRQOL. The aim of this study was to investigate the association between educational level and HRQOL in dialysis patients.

METHODS

In a single-center retrospective cross-sectional study HRQOL was measured using the Kidney Disease Quality of Life Short Form-36 (KDQOL-SF36) in prevalent chronic dialysis patients. Educational level was categorized into low, intermediate and high subgroups. Univariate and multivariate regression analyses were performed to assess the effects of age, gender, ethnicity, and dialysis vintage on the association between HRQOL and educational level.

RESULTS

One hundred twenty-nine chronic dialysis patients were included. Patients with an intermediate educational level had significantly higher odds of a higher emotional well-being than patients with a low educational level 4.37 (1.-89-10.13). A similar trend was found for a high educational level (OR 4.13 (1.04-16.42), p = 0.044) The odds for women compared to men were 2.83 (1.32-6.06) for better general health and 2.59 (1.15-5,84) for emotional well-being. There was no interaction between gender and educational level for both subdomains. Each year of increasing age significantly decreased physical functioning (OR 0.94 (0.91-0.97)).

CONCLUSIONS

Educational level and sex were associated with emotional well-being, since patients with intermediate and high educational level and females had better emotional well-being in comparison to patients with low educational level and males. Physical functioning decreased with increasing age.

Medication Adherence Barriers and Their Relationship to Health Determinants for Saudi Pediatric Dialysis Patients

Medication adherence is critical for the treatment and improved outcomes of chronic diseases. However, there is little research on the medication adherence of pediatric dialysis patients in Saudi Arabia. This study examines medication adherence barriers and their relationship to health determinants among Saudi children on dialysis, to enhance treatment success. We conducted a hospital-based, cross-sectional survey of pediatric dialysis patients using a simple random sampling technique. There is a trend of higher medication adherence for peritoneal dialysis patients compared with hemodialysis patients (36.1 ± 12.9 vs. 34.7 ± 8.3, p = 0.07). The leading barriers to medication adherence for all patients included being tired of taking the medication (score = 3.0256), not feeling like taking the medicine sometimes (score = 2.7436), bad taste (score = 2.5513), and forgetfulness (score = 2.41). Determinants of health were associated with medication adherence. Lack of education (56.4%) (some children underage for school) and chronic disease requirements (16.7%) were common barriers. After adjusting for the common confounders, the adherence scores increased significantly with increasing patient age (β = 2.378, p < 0.001), patients with working parents (β = 8.726, p = 0.011), and those living outside Riyadh (β = 19.198, p < 0.001). Medication adherence among pediatric dialysis patients is influenced by sociodemographic factors, health systems, and access to care. Evidence-based targeted interventions can increase medication adherence in this group on frequent dialysis. Future efforts should utilize systematic frameworks and digital health technologies to provide quality alternatives to improve medication adherence.

Differential item functioning of the CAHPS® In-Center Hemodialysis Survey

PURPOSE

End-stage renal disease patients' experience of care is an integral part of the assessment of the quality of the care provided at hemodialysis centers and is needed to promote patient choice, quality improvement, and accountability. The purpose of this study is to evaluate the In-Center Hemodialysis Consumer Assessment of Healthcare Providers and Systems (ICH-CAHPS®) survey and its equivalence in different age, gender, race, and education subgroups.

METHODS

The ICH-CAHPS survey was administered to 1454 patients from 32 dialysis facilities. For the characteristics compared, the sample had 756 participants younger than 65 years old, 739 men, 516 Black, 567 White, and 970 with less than high school diploma. Three different patient experience constructs were studied including nephrologist's communication and caring, quality of care and operations, and providing information to patients. We used item response theory analysis to examine the possibility of differential item functioning (DIF) by patient age, gender, race, and education separately after controlling for the other DIF characteristics and additional confounding variables including survey mode, mental, and general health status as well as duration on dialysis.

RESULTS

The three constructs studied were unidimensional and no major DIF was observed on the composites. Some non-equivalences were observed when confounders were not controlled for, suggesting that such covariates can be important factors in understanding the possibility of disparity in patients' experience.

CONCLUSIONS

The ICH-CAHPS is a promising survey to elicit hemodialysis patients' experience that has good psychometric properties and provides a standardized tool for assessing age, gender, race, or education disparity.

Socioeconomic status and mortality among dialysis patients: a systematic review and meta-analysis

BACKGROUND

The reported association between individual indicators of socioeconomic status (SES) and mortality in dialysis patients was inconsistent in previous studies. We performed a meta-analysis to identify the association between SES and mortality of dialysis population.

METHODS

The meta-analysis was conducted in accordance with MOOSE guidelines. Cohorts evaluating the association between SES indicators (income, education and occupation) and mortality in dialysis patients were included. Random-effects models were used to pool the adjusted relative risk (RR) from individual studies. Heterogeneity was assessed by Cochrane's Q and the I² statistic. Subgroup analyses and sensitivity analyses were performed to identify sources of heterogeneity and to evaluate the robustness of findings.

RESULTS

Fourteen studies were finally included. In hemodialysis patients, increased mortality was associated with lower level of income (RR = 1.08, 95%CI [1.01-1.16], P = 0.035; I² = 87.9%, P < 0.001) and occupation (RR = 1.63, 95%CI [1.11-2.38], P = 0.013; I² = 0.0%, P = 0.601). However, no significant association was identified for education (RR = 1.43, 95%CI [0.92-2.25]; P = 0.112; I² = 68.3%,P = 0.001). In patients receiving peritoneal dialysis, lower level of income (RR = 1.80, 95%CI [1.12-2.88],P = 0.015; I² = 75.9%, P = 0.042), education (RR = 1.27, 95%CI [1.13-1.43], P < 0.001; I² = 0.0%, P = 0.684), and occupation (RR = 3.42, 95% CI [1.35-8.70], P = 0.010) were risk factors for increased mortality. Subgroup analysis showed the association between SES indicators and mortality in hemodialysis differed according to geographic locations and study designs.

CONCLUSION

Lower SES (measured by income, education, and occupation) tends to be associated with higher mortality in patients receiving maintenance dialysis. But the magnitude of the associations varied for different individual indicators of SES.

Would government compensation of living kidney donors exploit the poor? An empirical analysis

Government compensation of kidney donors would likely increase the supply of kidneys and prevent the premature deaths of tens of thousands of patients with kidney failure each year. The major argument against it is that it would exploit the poor who would be more likely to accept the offers of compensation. This overlooks the fact that many poor patients desperately need a kidney transplant and would greatly benefit from an increased supply of kidneys. The objective of this study is to empirically test the hypothesis that government compensation of kidney donors would exploit the poor. Exploitation is defined by economists and several noted ethicists as paying donors less than the fair market value of their kidney. Exploitation is expressed in monetary terms and compared with the economic benefit recipients receive from a transplant. Data are from the Scientific Registry of Transplant Recipients and the United States Renal Data System annual data reports. Educational attainment is used as a proxy for income. We estimate that if the government rewards living donors with a package of non-cash benefits worth $75,000 per kidney, donors would not be exploited. Much more important, this compensation would likely end the kidney shortage, enabling many more patients with kidney failure to obtain transplants and live longer and healthier lives. The value of kidney transplantation to a U.S. recipient is about $1,330,000, which is an order of magnitude greater than any purported exploitation of a living donor (zero to $75,000). Consequently, the aggregate net benefit to the poor alone from kidney transplantation would increase to about $12 billion per year from $1 billion per year currently. Most of the benefit would accrue to poor kidney recipients. But poor donors would receive the fair market value of their kidney, and hence would not be exploited. If the government wanted to ensure that donors also received a net benefit, it could easily do so by increasing the compensation above $75,000 per donor.

Effects of socioeconomic status on physical and mental health of hemodialysis patients in Japan: differences by age, period, and cohort

Study purpose

Whether or not socioeconomic status (SES)-related differences in the health of hemodialysis patients differ by age, period, and birth cohort remains unclear. We examined whether SES-related gaps in physical and mental health change with age, period, and birth cohort for hemodialysis patients.

Methods

Data were obtained from repeated cross-sectional surveys conducted in 1996, 2001, 2006, and 2011, with members of a national patients’ association as participants. We used raking adjustment to create a database which had similar characteristics to the total sample of dialysis patients in Japan. SES was assessed using family size-adjusted income levels. We divided patients into three groups based on their income levels: below the first quartile, over the second quartile and under the third quartile, and over the fourth quartile. We used the number of dialysis complications as a physical health indicator and depressive symptoms as a mental health indicator. We used a cross-classified random-effects model that estimated fixed effects of age categories and period as level-1 factors, and random effects of birth cohort as level-2 factors.

Results

Relative risk of dialysis complications in respondents below the first quartile compared with ones over the fourth quartile was reduced in age categories >60 years. Mean differences in depressive symptoms between respondents below the first quartile and ones over the fourth quartile peaked in the 50- to 59-year-old age group, and were reduced in age groups >60 years. In addition, mean differences varied across periods, widening from 1996 to 2006. There were no significant birth cohort effects on income differences for dialysis complications or depressive symptoms.

Conclusion

The number of dialysis complications and depressive symptoms in dialysis patients were affected by income differences, and the degree of these differences changed with age category and period.

Characterization of the BRAZPD II cohort and description of trends in peritoneal dialysis outcome across time periods

Observational studies from different regions of the world provide valuable information in patient selection, clinical practice, and their relationship to patient and technique outcome. The present study is the first large cohort providing patient characteristics, clinical practice, patterns and their relationship to outcomes in Latin America. The objective of the present study was to characterize the cohort and to describe the main determinants of patient and technique survival, including trends over time of peritoneal dialysis (PD) initiation and treatment. This was a nationwide cohort study in which all incident adult patients on PD from 122 centers were studied. Patient demographics, socioeconomic and laboratory values were followed from December 2004 to January 2011 and, for comparison purposes, divided into 3 groups according to the year of starting PD: 2005/06, 2007/08 and 2009/10. Patient survival and technique failure (TF) were analyzed using the competing risk model of Fine and Gray. All patients active at the end of follow-up were treated as censored. In contrast, all patients who dropped the study for any reason different from the primary event of interest were treated as competing risk. Significance was set to a p level of 0.05. A total of 9,905 patients comprised the adult database, 7,007 were incident and 5,707 remained at least 90 days in PD. The main cause of dropout was death (54%) and of TF was peritonitis (63%). Technique survival at 1, 2, 3, 4, and 5 years was 91%, 84%, 77%, 68%, and 58%, respectively. There was no change in TF during the study period but 3 independent risk factors were identified: lower center experience, lower age, and automated PD (APD) as initial therapy. Cardiovascular disease (36%) was the main cause of death and the overall patient survival was 85%, 74%, 64%, 54%, and 48% at 1, 2, 3, 4, and 5 years, respectively. Patient survival improved along all study periods: compared to 2005/2006, patients starting at 2007/2008 had a relative risk reduction (SHR) of 0.83 (95% confidence interval [CI] 0.72 - 0.95); and starting in 2009/2010 of 0.69 (95% CI 0.57 - 0.83). The independent risk factors for mortality were diabetes, age > 65 years, previous hemodialysis, starting PD modality, white race, low body mass index (BMI), low educational level, center experience, length of pre-dialysis care, and the year of starting PD. We observed an improvement in patient survival along the years. This finding was sustained even after correction for several confounders and using a competing risk approach. On the other hand, no changes in technique survival were found.

Education level is associated with mortality in male patients undergoing maintenance hemodialysis

BACKGROUND

Studies of the correlation between education levels and mortality in hemodialysis (HD) patients are rare. The aim of this multi-center study was to investigate the relationship between education levels and 3-year mortality rates in HD patients.

METHODS

A total of 935 HD patients from 3 HD centers participated in this 3-year prospective observational study. Education levels were categorized as either less than senior high school and above or equal to senior high school. The causes of death and mortality rates were also analyzed for each subgroup.

RESULTS

At the end of the 3-year follow-up period, 164 patients had died. In the male group, forward stepwise Cox regression analysis revealed that age, HD duration, hypertension, creatinine level, serum albumin level ≥3.6 g/dl, anuria, Kt/Vurea, and high education level were significant predictive factors for 3-year mortality rates.

CONCLUSION

This prospective observational study demonstrated that education level was associated with mortality in men undergoing HD.

Frequency of and risk factors for poor cognitive performance in hemodialysis patients

OBJECTIVE

There are few detailed data on cognition in patients undergoing dialysis. We evaluated the frequency of and risk factors for poor cognitive performance using detailed neurocognitive testing.

METHODS

In this cross-sectional cohort study, 314 hemodialysis patients from 6 Boston-area hemodialysis units underwent detailed cognitive assessment. The neuropsychological battery assessed a broad range of functions, with established age-, sex-, and education-matched normative scores. Principal component analysis was used to derive composite scores for memory and executive function domains. Risk factors for each domain were evaluated using linear regression adjusting for age, sex, race, and education status. Analyses were repeated in those with Mini-Mental State Examination (MMSE) score ≥ 24.

RESULTS

Compared with population norms, patients on dialysis had significantly poorer executive function but not memory performance, a finding that persisted in the subgroup with MMSE score ≥ 24. In adjusted analyses, vascular risk factors and vascular disease were associated with lower executive function (p < 0.01).

CONCLUSIONS

There is a high frequency of poor cognitive performance in hemodialysis patients, primarily affecting executive function. Risk factors for worse executive function include vascular risk factors as well as vascular disease. Normal performance on the MMSE does not preclude impaired cognitive function, because individuals with MMSE score ≥ 24 also have a high frequency of poor cognitive performance.
