Cutting back on low-value health care practices supports sustainable kidney care.

July 2023 marked the hottest month on record, underscoring the urgent need for action on climate change. The imperative to reduce carbon emissions extends to all sectors, including health care, with it being responsible for 5.5% of global emissions. In decarbonizing health care, although much attention has focused on greening health care infrastructure and procurement, less attention has focused on reducing emissions through demand-side management. An important key element of this is reducing low-value care, given that ≈20% of global health care expenditure is considered low value. "Value" in health care, however, is subjective and dependent on how health outcomes are regarded. This review, therefore, examines the 3 main value perspectives specific to health care. Clinical effectiveness defines low-value care as interventions that offer little to no benefit or have a risk of harm exceeding benefits. Cost-effectiveness compares health outcomes versus costs compared with an alternative treatment. In this case, low-value care is care greater than a societal willingness to pay for an additional unit of health (quality-adjusted life year). Last, community perspectives emphasize the value of shared decision-making and patient-centered care. These values sit within broader societal values of ethics and equity. Any reduction in low-value care should, therefore, also consider patient autonomy, societal value perspectives and opportunity costs, and equity. Deimplementing entrenched low-value care practices without unnecessarily compromising ethics and equity will require tailored strategies, education, and transparency.

Mind the gap in kidney care: translating what we know into what we do.

Historically, it takes an average of 17 years to move new treatments from clinical evidence to daily practice. Given the highly effective treatments now available to prevent or delay kidney disease onset and progression, this is far too long. The time is now to narrow the gap between what we know and what we do. Clear guidelines exist for the prevention and management of common risk factors for kidney disease, such as hypertension and diabetes, but only a fraction of people with these conditions worldwide are diagnosed, and even fewer are treated to target. Similarly, the vast majority of people living with kidney disease are unaware of their condition, because in the early stages it is often silent. Even among patients who have been diagnosed, many do not receive appropriate treatment for kidney disease. Considering the serious consequences of kidney disease progression, kidney failure, or death, it is imperative that treatments are initiated early and appropriately. Opportunities to diagnose and treat kidney disease early must be maximized beginning at the primary care level. Many systematic barriers exist, ranging from patient to clinician to health systems to societal factors. To preserve and improve kidney health for everyone everywhere, each of these barriers must be acknowledged so that sustainable solutions are developed and implemented without further delay.

Potential utility of renal functional reserve testing in clinical nephrology.

PURPOSE OF REVIEW: The aim of this review is to discuss the concept of renal functional reserve (RFR) and its potential relevance in clinical practice. RECENT FINDINGS: The RFR is a measure of the change in glomerular filtration rate (GFR) from baseline to a peak value when the kidney is stimulated to increase its function. This concept has a strong physiologic basis in nephrology and the presence, magnitude or absence of RFR capacity may have prognostic significance in many clinical scenarios where individuals are at risk of hyperfiltration or kidney dysfunction. Unlike in other medical specialties, where organ reserve function is reliably measurable and used routinely, measurement of RFR in nephrology has not been integrated into clinical care. Methodologic challenges including standardization of methods to stimulate GFR and the ability of measures of GFR to discriminate acute dynamic changes in GFR upon kidney stimulation have hampered the robustness and use of RFR measurements in research and clinical care. SUMMARY: Given the emergence of many new disease-modifying therapies in nephrology, it is imperative that we move forward and develop more robust tools to further our understanding of kidney physiology and pathophysiology, such as the RFR, which should be integrated into research and clinical care to support optimal personalization of therapeutic kidney care strategies.

Climate change and its influence in nephron mass.

PURPOSE OF REVIEW: The consequences of climate change, including heat and extreme weather events impact kidney function in adults and children. The impacts of climate change on kidney development during gestation and thereby on kidney function later in life have been poorly described. Clinical evidence is summarized to highlight possible associations between climate change and nephron mass. RECENT FINDINGS: Pregnant women are vulnerable to the effects of climate change, being less able to thermoregulate, more sensitive to the effects of dehydration, and more susceptible to infections. Exposure to heat, wildfire smoke, drought, floods and climate-related infections are associated with low birth weight, preterm birth and preeclampsia. These factors are associated with reduced nephron numbers, kidney dysfunction and higher blood pressures in offspring in later life. Exposure to air pollution is associated with higher blood pressures in children and has variable effects on estimated glomerular filtration rate. SUMMARY: Climate change has important impacts on pregnant women and their unborn children. Being born too small or too soon is associated with life-time risk of kidney disease. Climate change may therefore have a dual effect of impacting fetal kidney development and contributing to cumulative postnatal kidney injury. The impact on population kidney health of future generations may be significant.

Equity and Quality of Global Chronic Kidney Disease Care: What Are We Waiting for?

BACKGROUND: Chronic kidney disease (CKD) is an important but insufficiently recognized public health problem. Unprecedented advances in delaying progression of CKD and reducing kidney failure and death have been made in recent years, with the addition of the sodium-glucose cotransporter 2 inhibitors and other newer medication to the established standard of care with inhibitors of the renin-angiotensin system. Despite knowledge of these effective therapies, their prescription and use remain suboptimal globally, and more specially in low resource settings. Many challenges contribute to this gap between knowledge and translation into clinical care, which is even wider in lower resource settings across the globe. Implementation of guideline-directed care is hampered by lack of disease awareness, late or missed diagnosis, clinical inertia, poor quality care, cost of therapy, systemic biases, and lack of patient empowerment. All of these are exacerbated by the social determinants of health and global inequities. SUMMARY: CKD is a highly manageable condition but requires equitable and sustainable access to quality care supported by health policies, health financing, patient and health care worker education, and affordability of medications and diagnostics. KEY MESSAGES: The gap between the knowledge and tools to treat CKD and the implementation of optimal quality kidney care should no longer be tolerated. Advocacy, research and action are required to improve equitable access to sustainable quality care for CKD everywhere.

Global Kidney Health priorities - Perspectives from the ISN-GKHA.

Kidney diseases have become a global epidemic with significant public health impact. Chronic kidney disease (CKD) is set to become the fifth largest cause of death by 2040, with major impacts on low-resource countries. This review is based on recent report of the International Society of Nephrology Global Kidney Health Atlas (ISN-GKHA) that uncovered gaps in key vehicles of kidney care delivery assessed using World Health Organization building blocks for health systems (financing, services delivery, workforce, access to essential medicines, health information systems, and leadership/governance). High-income countries had more centres for kidney replacement therapies (KRT), higher KRT access, higher allocation of public funds to KRT, larger workforce, more health information systems, and higher government recognition of CKD and KRT as health priorities than low-income nations. Evidence identified from the current ISN-GKHA initiative should serve as template for generating and advancing policies and partnerships to address the global burden of kidney disease. The results provide opportunities for kidney health policymakers, nephrology leaders, and organizations to initiate consultations to identify strategies for improving care delivery and access in equitable, and resource-sensitive manners. Policies to increase use of public funding for kidney care, lower cost of KRT, and increase workforce should be high-priority in low-resource nations, while strategies that expand access to kidney care and maintain current status of care should be prioritized in high-income countries. In all countries, the perspectives of people with CKD should be exhaustively explored to identify core kidney care priorities.

Prescribing the dialysis dose and treatment frequency in home haemodialysis.

BACKGROUND: There is growing interest in home haemodialysis (HHD) performed with low-flow dialysate devices and variable treatment schedules. The target standard Kt/V (stdKt/V) should be 2.3 volumes/week, according to KDOQI guidelines (2015). The current formula for stdKt/V does not help prescribe the dialysis dose (eKt/V) and treatment frequency (TF). The aim of this study was to obtain a formula for stdKt/V that is able to define the minimum required values of eKt/V and TF to achieve the targeted stdKtV. METHODS: Thirty-eight prevalent patients on HHD were enrolled. A total of 231 clinical datasets were available for urea modelling using the Solute-Solver software (SS), recommended by KDOQI guidelines. A new formula (stdKt/V = a + b × Kru + c × eKt/V) was obtained from multivariable regression analysis of stdKt/V vs eKt/V and residual kidney urea clearance (Kru). The values of coefficients a, b and c depend on the treatment schedules and the day of the week of blood sampling for the kinetic study (labdayofwk) and then vary for each of their foreseen 62 combinations. For practical purposes, we used only seven combinations, assuming Monday as a labdayofwk for each of the most common schedules of the 7 days of the week. RESULTS: The stdKt/V values obtained with SS were compared with the paired ones obtained with the formula. The mean ± standard deviation stdKt/V values obtained with SS and the formula were 3.043 ± 0.530 and 2.990 ± 0.553, respectively, with 95% confidence interval +0.15 to -0.26. A 'prescription graph' was built using the formula to draw lines expressing the relationship between Kru and required eKt/V for each TF. Using this graph, TF could have been reduced from the delivered 5.8 ± 0.8 to 4.8 ± 0.8 weekly sessions. CONCLUSIONS: The new formula for stdKtV is reliable and can support clinicians to prescribe the dialysis dose and TF in patients undergoing HHD.

Evaluation of the implementation of a "Pediatric Feasibility Assessment for Transplantation" tool in children and adolescents at Red Cross War Memorial Children's Hospital, Cape Town, South Africa.

BACKGROUND: Kidney transplantation remains the treatment of choice for children with kidney failure (KF). In South Africa, kidney replacement therapy (KRT) is restricted to children eligible for transplantation. This study reports on the implementation of the Paediatric Feasibility Assessment for Transplantation (pFAT) tool, a psychosocial risk score developed in South Africa to support transparent transplant eligibility assessment in a low-resource setting. METHODS: Single-center retrospective descriptive analysis of children assessed for KRT using pFAT tool from 2015 to 2021. RESULTS: Using the pFAT form, 88 children (median [range] age 12.0 [1.1 to 19.0] years) were assessed for KRT. Thirty (34.1%) children were not listed for KRT, scoring poorly in all domains, and were referred for supportive palliative care. Fourteen of these 30 children (46.7%) died, with a median survival of 6 months without dialysis. Nine children were reassessed and two were subsequently listed. Residing >300 km from the hospital (p = .009) and having adherence concerns (p = .003) were independently associated with nonlisting. Of the 58 (65.9%) children listed for KRT, 40 (69.0%) were transplanted. One-year patient and graft survival were 97.2% and 88.6%, respectively. Only one of the four grafts lost at 1-year posttransplant was attributed to psychosocial issues. CONCLUSIONS: Short-term outcomes among children listed using the pFAT form are good. Among those nonlisted, the pFAT highlights specific psychosocial/socioeconomic barriers, over which most children themselves have no power to change, which should be systemically addressed to permit eligibility of more children and save lives.

Eculizumab in Shiga toxin-producing Escherichia coli hemolytic uremic syndrome: a systematic review.

BACKGROUND: Infection-associated hemolytic uremic syndrome (IA-HUS), most often due to infection with Shiga toxin-producing bacteria, mainly affects young children. It can be acutely life-threatening, as well as cause long-term kidney and neurological morbidity. Specific treatment with proven efficacy is lacking. Since activation of the alternative complement pathway occurs in HUS, the monoclonal C5 antibody eculizumab is often used off-label once complications, e.g., seizures, occur. Eculizumab is prohibitively expensive and carries risk of infection. Its utility in IA-HUS has not been systematically studied. This systematic review aims to present, summarize, and evaluate all currently available data regarding the effect of eculizumab administration on medium- to long-term outcomes (i.e., outcomes after the acute phase, with a permanent character) in IA-HUS. METHODS: PubMed, Embase, and Web of Science were systematically searched for studies reporting the impact of eculizumab on medium- to long-term outcomes in IA-HUS. The final search occurred on March 2, 2022. Studies providing original data regarding medium- to long-term outcomes in at least 5 patients with IA-HUS, treated with at least one dose of eculizumab during the acute illness, were included. No other restrictions were imposed regarding patient population. Studies were excluded if data overlapped substantially with other studies, or if outcomes of IA-HUS patients were not reported separately. Study quality was assessed using the ROBINS-I tool for risk of bias in non-randomized studies of interventions. Data were analyzed descriptively. RESULTS: A total of 2944 studies were identified. Of these, 14 studies including 386 eculizumab-treated patients met inclusion criteria. All studies were observational. Shiga toxin-producing E. coli (STEC) was identified as the infectious agent in 381 of 386 patients (98.7%), effectively limiting the interpretation of the data to STEC-HUS patients. Pooling of data across studies was not possible. No study reported a statistically significant positive effect of eculizumab on any medium- to long-term outcome. Most studies were, however, subject to critical risk of bias due to confounding, as more severely ill patients received eculizumab. Three studies attempted to control for confounding through patient matching, although residual bias persisted due to matching limitations. DISCUSSION: Current observational evidence does not permit any conclusion regarding the impact of eculizumab in IA-HUS given critical risk of bias. Results of randomized clinical trials are eagerly awaited, as new therapeutic strategies are urgently needed to prevent long-term morbidity in these severely ill patients.

A 6-year review of acute post-streptococcal glomerulonephritis at a public children's hospital in Cape Town, South Africa.

BACKGROUND: Acute post-streptococcal glomerulonephritis (APSGN) is the most common cause of acute nephritis in children globally and, in some cases, may be associated with progressive kidney injury and failure, cumulating in the need for long-term dialysis and/or kidney transplantation. METHODS: Our retrospective study describes the occurrence of APSGN among children (< 14 years) admitted to a tertiary children's hospital in Cape Town, South Africa, from January 2015 to December 2020. RESULTS: Of 161 children who presented with acute nephritis (haematuria, oedema, oliguria, and hypertension), 100 met the inclusion criteria. Demographic, clinical features, laboratory findings, management, and outcome data were collected. APSGN was defined by the clinical presentation of at least two clinical signs of acute nephritis, and low serum complement 3 (C3) level or evidence of a recent streptococcal infection. Most cases of APSGN were associated with streptococcal skin infections: 55/100 (55%); 10/100 (10%) children presented with hypertensive seizures; C3 levels were low in 86/92 (93.5%) children; 94/94 (100%) children had elevated anti-deoxyribonuclease-B (anti-DNase-B) levels; and 80/94 (85%) also had elevated anti-streptolysin O titre (ASOT) at presentation. Eleven (11%) children had a percutaneous kidney biopsy; 4/11 (36%) showed histological features of post-infectious nephritis, and 7/11(64%) also had crescentic glomerulonephritis with immune complex deposits. Sixty-two (62%) children confirmed recovered, and five (5%) progressed to kidney failure, but 29 presumed recovered as they did not return for follow-up to our institution. CONCLUSIONS: Childhood APSGN remains an important health problem in South Africa (SA) with favourable outcomes in most, apart from those with crescentic glomerulonephritis who progressed to kidney failure.

Dialysis for paediatric acute kidney injury in Cape Town, South Africa.

BACKGROUND: Dialysis is lifesaving for acute kidney injury (AKI), but access is poor in less resourced settings. A "peritoneal dialysis (PD) first" policy for paediatric AKI is more feasible than haemodialysis in low-resource settings. METHODS: Retrospective review of modalities and outcomes of children dialysed acutely at Red Cross War Memorial Children's Hospital between 1998 and 2020. RESULTS: Of the 593 children with AKI who received dialysis, 463 (78.1%) received PD first. Median age was 9.0 (range 0.03-219.3; IQR 13.0-69.6) months; 57.6% were < 1 year old. Weights ranged from 0.9 to 2.0 kg (median 7.0 kg, IQR 3.0-16.0 kg); 38.6% were < 5 kg. PD was used more in younger children compared to extracorporeal dialysis (ECD), with median ages 6.4 (IQR 0.9-30.4) vs. 73.9 (IQR 17.5-113.9) months, respectively (p = 0.001). PD was performed with Seldinger soft catheters (n = 480/578, 83%), predominantly inserted by paediatricians at the bedside (n = 412/490, 84.1%). Complications occurred in 127/560 (22.7%) children receiving PD. Overall, 314/542 (57.8%) children survived. Survival was significantly lower in neonates (< 1 month old, 47.5%) and infants (1-12 months old, 49.2%) compared with older children (> 1 year old, 70.4%, p < 0.0001). Survival was superior in the ECD (75.4%) than in the PD group (55.6%, p = 0.002). CONCLUSIONS: "PD First for Paediatric AKI" is a valuable therapeutic approach for children with AKI. It is feasible in low-resourced settings where bedside PD catheter insertion can be safely taught and is an acceptable dialysis modality, especially in settings where children with AKI would otherwise not survive.

Assessment of South Asian Pediatric Acute Kidney Injury: Epidemiology and Risk Factors (ASPIRE)-a prospective study on "severe dialysis dependent pediatric AKI".

BACKGROUND: Pediatric acute kidney injury (AKI) is a global health concern with an associated mortality risk disproportionately pronounced in resource-limited settings. There is a pertinent need to understand the epidemiology of pediatric AKI in vulnerable populations. Here, we proposed a prospective study to investigate the epidemiology and associated risk factors of "severe dialysis dependent AKI" in children among South Asian nations which would be the first and largest of its kind. METHODS: The ASPIRE study (part of PCRRT-ICONIC Foundation initiative) is a multi-center, prospective observational study conducted in South Asian countries. All children and adolescents ≤ 18 years of age who required dialysis for AKI in any of the collaborating medical centers were enrolled. Data collection was performed until one of the following endpoints was observed: (1) discharge, (2) death, and (3) discharge against medical advice. RESULTS: From 2019 to 2022, a total of 308 children with severe AKI were enrolled. The mean age was 6.17 years (63% males). Secondary AKI was more prevalent than primary AKI (67.2%), which predominantly occurred due to infections, dehydration, and nephrotoxins. Common causes of primary AKI were glomerulonephritis, hemolytic uremic syndrome, lupus nephritis, and obstructive uropathy. Shock, need for ventilation, and coagulopathy were commonly seen in children with severe AKI who needed dialysis. The foremost kidney replacement therapy used was peritoneal dialysis (60.7%). The mortality rate was 32.1%. CONCLUSIONS: Common causes of AKI in children in South Asia are preventable. Mortality is high among these children suffering from "severe dialysis dependent AKI." Targeted interventions to prevent and identify AKI early and initiate supportive care in less-resourced nations are needed.

Mind the gap in kidney care: Translating what we know into what we do.

Historically, it takes an average of 17 years to move new treatments from clinical evidence to daily practice. Given the highly effective treatments now available to prevent or delay kidney disease onset and progression, this is far too long. The time is now to narrow the gap between what we know and what we do. Clear guidelines exist for the prevention and management of common risk factors for kidney disease, such as hypertension and diabetes, but only a fraction of people with these conditions worldwide are diagnosed, and even fewer are treated to target. Similarly, the vast majority of people living with kidney disease are unaware of their condition, because in the early stages it is often silent. Even among patients who have been diagnosed, many do not receive appropriate treatment for kidney disease. Considering the serious consequences of kidney disease progression, kidney failure, or death, it is imperative that treatments are initiated early and appropriately. Opportunities to diagnose and treat kidney disease early must be maximized beginning at the primary care level. Many systematic barriers exist, ranging from patient to clinician to health systems to societal factors. To preserve and improve kidney health for everyone everywhere, each of these barriers must be acknowledged so that sustainable solutions are developed and implemented without further delay.

Global variations in funding and use of hemodialysis accesses: an international report using the ISN Global Kidney Health Atlas.

BACKGROUND: There is a lack of contemporary data describing global variations in vascular access for hemodialysis (HD). We used the third iteration of the International Society of Nephrology Global Kidney Health Atlas (ISN-GKHA) to highlight differences in funding and availability of hemodialysis accesses used for initiating HD across world regions. METHODS: Survey questions were directed at understanding the funding modules for obtaining vascular access and types of accesses used to initiate dialysis. An electronic survey was sent to national and regional key stakeholders affiliated with the ISN between June and September 2022. Countries that participated in the survey were categorized based on World Bank Income Classification (low-, lower-middle, upper-middle, and high-income) and by their regional affiliation with the ISN. RESULTS: Data on types of vascular access were available from 160 countries. Respondents from 35 countries (22% of surveyed countries) reported that > 50% of patients started HD with an arteriovenous fistula or graft (AVF or AVG). These rates were higher in Western Europe (n = 14; 64%), North & East Asia (n = 4; 67%), and among high-income countries (n = 24; 38%). The rates of > 50% of patients starting HD with a tunneled dialysis catheter were highest in North America & Caribbean region (n = 7; 58%) and lowest in South Asia and Newly Independent States and Russia (n = 0 in both regions). Respondents from 50% (n = 9) of low-income countries reported that > 75% of patients started HD using a temporary catheter, with the highest rates in Africa (n = 30; 75%) and Latin America (n = 14; 67%). Funding for the creation of vascular access was often through public funding and free at the point of delivery in high-income countries (n = 42; 67% for AVF/AVG, n = 44; 70% for central venous catheters). In low-income countries, private and out of pocket funding was reported as being more common (n = 8; 40% for AVF/AVG, n = 5; 25% for central venous catheters). CONCLUSIONS: High income countries exhibit variation in the use of AVF/AVG and tunneled catheters. In low-income countries, there is a higher use of temporary dialysis catheters and private funding models for access creation.

Shared decision making in patients with kidney failure.

'Elderly' is most commonly defined as an individual aged 65 years or older. However, this definition fails to account for the differences in genetics, lifestyle and overall health that contribute to significant heterogeneity among the elderly beyond chronological age. As the world population continues to age, the prevalence of chronic diseases, including chronic kidney disease (CKD), is increasing and CKD frequently progresses to kidney failure. Moreover, frailty represents a multidimensional clinical entity highly prevalent in this population, which needs to be adequately assessed to inform and support medical decisions. Selecting the optimal treatment pathway for the elderly and frail kidney failure population, be it hemodialysis, peritoneal dialysis, or conservative kidney management is complex, because of the presence of comorbidities associated with low survival rates and impaired quality of life. Management of these patients should involve a multidisciplinary approach including doctors from various specialties, nurses, psychologists, dieticians, and physiotherapists. Studies are mostly retrospective and observational, lacking adjustment for confounders or address selection and indication biases, making it difficult to use these data to guide treatment decisions. Throughout this review we discuss the difficulty of making a one-size-fits-all recommendation for the clinical needs of older patients with kidney failure. We advocate that a research agenda for optimization of the critical issues we present in this review be implemented. We recommend prospective studies that address these issues, and systematic reviews incorporating the complementary evidence of both observational and interventional studies. Furthermore, we strongly support a shared decision making process matching evidence with patient preferences to ensure that individualized choices are made regarding dialysis vs. conservative kidney management, dialysis modality, and optimal vascular access.

Impact of early life development on later onset chronic kidney disease and hypertension and the role of evolutionary trade-offs.

NEW FINDINGS: What is the topic of this review? In this report, we summarize the latest clinical evidence linking developmental programming in the kidney to later life blood pressure and kidney disease. What advances does it highlight? Population-level studies now show convincingly that low birth weight, fetal growth restriction and preterm birth are associated with and have a synergistic impact on the risk of kidney disease in later life. A new approach also considers how evolutionary selection pressure might fail to select for long-term robustness of kidney function. ABSTRACT: The global burden of kidney disease is high and rising. The risk of kidney disease among individuals is highly variable, in part related to genetic and environmental factors, but also likely to be modulated by developmental programming of the number of nephrons and kidney function in fetal life. The number of nephrons varies widely across the population and is lower among those who were born small or preterm. Population registry evidence clearly shows an association between these birth circumstances and later-life risk of hypertension and kidney disease, not only for chronic kidney disease but also for acquired kidney disease, demonstrating an inherent susceptibility to kidney disease in these individuals. Gestational stressors impact kidney development, a process that is likely to be layered upon the evolutionary history of the kidney and how the organ has developed in response to selection pressure to support reproductive capacity in early adulthood, but not to withstand multiple stresses later in life. Reducing the global burden of kidney disease in future generations will require both individual- and population/environment-level risks to be addressed.

Challenges to the right to health in sub-Saharan Africa: reflections on inequities in access to dialysis for patients with end-stage kidney failure.

Realization of the individual's right to health in settings such as sub-Saharan Africa, where health care adequate resources are lacking, is challenging. This paper demonstrates this challenge by illustrating the example of dialysis, which is an expensive but life-saving treatment for people with kidney failure. Dialysis resources, if available in sub-Saharan Africa, are generally limited but in high demand, and clinicians at the bedside are faced with deciding who lives and who dies. When resource limitations exist, transparent and objective priority setting regarding access to such expensive care is required to improve equity across all health needs in a population. This process however, which weighs individual and population health needs, denies some the right to health by limiting access to health care.This paper unpacks what it means to recognize the right to health in sub-Saharan Africa, acknowledging the current resource availability and scarcity, and the larger socio-economic context. We argue, the first order of the right to health, which should always be realized, includes protection of health, i.e. prevention of disease through public health and health-in-all policy approaches. The second order right to health care would include provision of universal health coverage to all, such that risk factors and diseases can be effectively and equitably detected and treated early, to prevent disease progression or development of complications, and ultimately reduce the demand for expensive care. The third order right to health care would include equitable access to expensive care. In this paper, we argue that recognition of the inequities in realization of the right to health between individuals with "expensive" needs versus those with more affordable needs, countries must determine if, how, and when they will begin to provide such expensive care, so as to minimize these inequities as rapidly as possible. Such a process requires good governance, multi-stakeholder engagement, transparency, communication and a commitment to progress. We conclude the paper by emphasizing that striving towards the progressive realization of the right to health for all people living in SSA is key to achieving equity in access to quality health care and equitable opportunities for each individual to maximize their own state of health.

TB in paediatric kidney transplant recipients - A single-centre experience.

BACKGROUND: TB remains a major challenge in transplantation, particularly in endemic countries. This study aimed to describe the incidence, clinical presentation and outcomes of TB in paediatric kidney transplant recipients and to assess the impact of INH prophylaxis. METHODS: Single-centre retrospective descriptive analysis of children who received kidney transplants from 1995 to 2019 was carried out. The cohort was stratified according to receipt of INH prophylaxis which began in 2005. RESULTS: A total of 212 children received a kidney transplant during the study period. Median age at transplantation was 11.2 years (IQR: 2.2-17.9), and 56% were males. TB was diagnosed in 20 (9%) children, with almost two-thirds (n = 12) occurring within the first year. Most infections were pulmonary. The main presenting symptoms included fever (n = 13/20), weight loss (n = 12/20) and cough (n = 10/20). TST was positive in four of 20 children. Coinfection with EBV, CMV or Staph was found in five children. Due to drug interactions, an up to threefold increase in calcineurin inhibitor dose was required to maintain therapeutic blood levels. INH prophylaxis was protective against development of TB (p = .04). Gender, age and type of allograft were not significant risk factors. Graft and patient survival was 100% upon completion of TB treatment. CONCLUSION: Kidney transplant recipients in endemic countries have a high risk of developing TB. Diagnosis remains a challenge. Frequent and meticulous monitoring of immunosuppression drug levels during treatment of TB is required to avoid loss of patient or graft. INH prophylaxis protects against development of TB in this population.

Bedside rationing and moral distress in nephrologists in sub- Saharan Africa.

BACKGROUND: Kidney diseases constitute an important proportion of the non-communicable disease (NCD) burden in Sub-Saharan Africa (SSA), though prevention, diagnosis and treatment of kidney diseases are less prioritized in public health budgets than other high-burden NCDs. Dialysis is not considered cost-effective, and for those patients accessing the limited service available, high out-of-pocket expenses are common and few continue care over time. This study assessed challenges faced by nephrologists in SSA who manage patients needing dialysis. The specific focus was to investigate if and how physicians respond to bedside rationing situations. METHODS: A survey was conducted among a randomly selected group of nephrologists from SSA. The questionnaire was based on a previously validated survey instrument. A descriptive and narrative approach was used for analysis. RESULTS: Among 40 respondents, the majority saw patients weekly with acute kidney injury (AKI) or end-stage kidney failure (ESKF) in need of dialysis whom they could not dialyze. When dialysis was provided, clinical compromises were common, and 66% of nephrologists reported lack of basic diagnostics and medication and > 80% reported high out-of-pocket expenses for patients. Several patient-, disease- and institutional factors influenced who got access to dialysis. Patients' financial constraints and poor chances of survival limited the likelihood of receiving dialysis (reported by 79 and 78% of nephrologists respectively), while a patient's being the family bread-winner increased the likelihood (reported by 56%). Patient and institutional constraints resulted in most nephrologists (88%) frequently having to make difficult choices, sometimes having to choose between patients. Few reported existence of priority setting guidelines. Most nephrologists (74%) always, often or sometimes felt burdened by ethical dilemmas and worried about patients out of hospital hours. As a consequence, almost 46% of nephrologists reported frequently regretting their choice of profession and 26% had considered leaving the country. CONCLUSION: Nephrologists in SSA face harsh priority setting at the bedside without available guidance. The moral distress is high. While publicly funded dialysis treatment might not be prioritized in essential health care packages on the path to universal health coverage, the suffering of the patients, families and the providers must be acknowledged and addressed to increase fairness in these decisions.

Hemodialysis Use and Practice Patterns: An International Survey Study.

RATIONALE & OBJECTIVE: Hemodialysis (HD) is the most common form of kidney replacement therapy. This study aimed to examine the use, availability, accessibility, affordability, and quality of HD care worldwide. STUDY DESIGN: A cross-sectional survey. SETTING & PARTICIPANTS: Stakeholders (clinicians, policy makers, and consumer representatives) in 182 countries were convened by the International Society of Nephrology from July to September 2018. OUTCOMES: Use, availability, accessibility, affordability, and quality of HD care. ANALYTICAL APPROACH: Descriptive statistics. RESULTS: Overall, representatives from 160 (88%) countries participated. Median country-specific use of maintenance HD was 298.4 (IQR, 80.5-599.4) per million population (pmp). Global median HD use among incident patients with kidney failure was 98.0 (IQR, 81.5-140.8) pmp and median number of HD centers was 4.5 (IQR, 1.2-9.9) pmp. Adequate HD services (3-4 hours 3 times weekly) were generally available in 27% of low-income countries. Home HD was generally available in 36% of high-income countries. 32% of countries performed monitoring of patient-reported outcomes; 61%, monitoring of small-solute clearance; 60%, monitoring of bone mineral markers; 51%, monitoring of technique survival; and 60%, monitoring of patient survival. At initiation of maintenance dialysis, only 5% of countries used an arteriovenous access in almost all patients. Vascular access education was suboptimal, funding for vascular access procedures was not uniform, and copayments were greater in countries with lower levels of income. Patients in 23% of the low-income countries had to pay >75% of HD costs compared with patients in only 4% of high-income countries. LIMITATIONS: A cross-sectional survey with possibility of response bias, social desirability bias, and limited data collection preventing in-depth analysis. CONCLUSIONS: In summary, findings reveal substantial variations in global HD use, availability, accessibility, quality, and affordability worldwide, with the lowest use evident in low- and lower-middle-income countries.
