Home Dialysis in the United States: A Roadmap for Increasing Peritoneal Dialysis Utilization

Peritoneal Dialysis Technique Survival: A Cohort Study

RATIONALE & OBJECTIVE

Reasons for transfer from peritoneal dialysis (PD) to hemodialysis (HD) remain incompletely understood. Among incident and prevalent patients receiving PD, we evaluated the association between prior treatment with HD and PD technique survival.

STUDY DESIGN

Retrospective cohort study.

SETTING & PARTICIPANTS

Adults who initiated PD at a Dialysis Clinic, Inc. (DCI) outpatient facility between January 1, 2010 and September 30, 2019.

EXPOSURES

The primary exposure of interest was timing of PD start, categorized as PD-first, PD-early, or PD-late. Other covariates included demographics, clinical characteristics, and routine laboratory results.

OUTCOMES

Modality switch from PD to HD sustained for more than 90 days.

ANALYTICAL APPROACH

Multivariable Fine-Gray models with competing risks and time-varying covariates, stratified at 9 months to account for lack of proportionality.

RESULTS

Among 5224 patients who initiated PD at a DCI facility, 3174 initiated dialysis with PD ("PD-first"), 942 transitioned from HD to PD within 90 days ("PD-early"), and 1108 transitioned beyond 90 days ("PD-late"); 1472 (28%) subsequently transferred from PD to HD. PD-early and PD-late patients had higher risk of transfer to HD as compared to PD-first patients [adjusted hazard ratio (aHR) 1.51 (95% CI: 1.17-1.96) and 2.41 (1.94-3.00), respectively, in the first 9 months and aHR 1.16 (0.99-1.35) and 1.43 (1.24-1.65), respectively, after 9 months]. More peritonitis episodes, fewer home visits, lower serum albumin, lower residual kidney function, and lower peritoneal clearance calculated with weekly Kt/V were additional risk factors for PD-to-HD transfer.

LIMITATIONS

Missing data on dialysis adequacy and residual kidney function, confounded by short PD technique survival.

CONCLUSIONS

Initiating dialysis with PD is associated with greater PD technique survival, though many of those who initiate PD late in their dialysis course still experience substantial time on PD. Peritonitis, lower serum albumin, and lower Kt/V are risk factors for PD-to-HD transfer that may be amenable to intervention.

Exploring Preconceptions as Barriers to Peritoneal Dialysis Eligibility: A Global Scenario-Based Survey of Kidney Care Physicians

Introduction

Despite the growing number of patients requiring kidney replacement therapy (KRT), peritoneal dialysis (PD) is underutilized globally. A contributory factor may be clinician myths about its use. The aim of this study was to explore perceptions about PD initiation by clinicians according to various physical, social, and clinical characteristics of patients.

Methods

An online global survey (in English and Thai) was administered to ascertain nephrologists' and nephrology trainees' decisions on recommending PD as a treatment modality.

Results

A total of 645 participants (522 nephrologists and 123 trainees; 56% male) from 54 countries (66% from high-income countries [HICs], 22% from upper middle-income countries [UMICs], 12% from lower middle-income countries, and 1% from low-income countries [LICs]) completed the survey. Of the respondents, 81% identified as attending physicians or consultants, and 19% identified as trainees or other. PD was recommended for most scenarios, including repeated exposures to heavy lifting, swimming (especially in a private pool and ocean), among patients with cirrhosis or cognitive impairment with available support, and those living with a pet if a physical separation can be achieved during PD. Certain abdominal surgeries were more acceptable to proceed with PD (hysterectomy, 90%) compared to others (hemicolectomy, 45%). Similar variation was noted for different types of stomas (nephrostomies, 74%; suprapubic catheters, 53%; and ileostomies, 27%).

Conclusion

The probability of recommending PD in various scenarios was greater among clinicians from HICs, larger units, and consultants with more clinical experience. There is a disparity in recommending PD across various clinical scenarios driven by experience, unit-level characteristics, and region of practice. Globally, evidence-informed education is warranted to rectify misconceptions to enable greater PD uptake.

Inpatient peritoneal dialysis catheters placed across the United States during a 3-year period: Lessons learned from 15,000 patients

BACKGROUND

Peritoneal dialysis is a popular option for patients with end-stage renal disease. A recent presidential executive order has incentivized in-home end-stage renal disease treatments, leading to an increase in peritoneal dialysis use. Guidelines exist for creating and maintaining peritoneal dialysis access without addressing the optimal technique. This study evaluates nationwide peritoneal dialysis catheter placement practices and their long-term outcomes.

METHODS

Retrospective cohort analysis of Nationwide Readmission Database from 2017 to 2019. Patients with end-stage renal disease undergoing inpatient peritoneal dialysis catheter placement were included. Six-month readmissions, mortality, and peritoneal dialysis catheter-specific outcome measures were assessed among survivors of admission, including catheter leakage, mechanical breakdown, displacement, revision or replacement, removal, exit site infections, intra-abdominal abscess, and sepsis. Binary logistic regression analyses were performed.

RESULTS

In the study, 14,863 patients with inpatient peritoneal dialysis catheter insertions were identified, of which 7,096 were analyzed (4,150 [59%] laparoscopic, 1,781 [25%] fluoroscopic, 1,165 [16%] open), 847 (12%) had major complications, 931 (13%) were readmitted, and 102 (1.4%) died within 6 months. Univariate analyses demonstrated that laparoscopy had higher mechanical complications, exit-site infections, catheter revision, and removal within 6 months, and fluoroscopy had higher sepsis and mortality. Multivariate analyses showed fluoroscopy was associated with intraabdominal abscess (adjusted odds ratio, 2.36; P = .025), laparoscopy with exit-site infections (adjusted odds ratio, 0.49; P = .005), and open surgery with catheter displacement (adjust odds ratio, 2.95; P = .021).

CONCLUSION

This is the first large-scale study on inpatient peritoneal dialysis catheter placement outcomes in the United States. Fluoroscopic and open surgical placements are routinely performed, but laparoscopy remains the mainstay with fewer exit-site infections. Overall, peritoneal dialysis is a safe option, with 1 in 9 patients having an infectious or mechanical complication within 6 months. Furthermore, large-scale prospective studies are warranted to identify the optimal placement technique.

Home Dialysis in Patients with Cardiovascular Diseases

Kidney failure with replacement therapy and cardiovascular disease are frequently comorbid. In patients with kidney failure with replacement therapy, cardiovascular disease is a major contributor to morbidity and mortality. Conventional thrice-weekly in-center dialysis confers risk factors for cardiovascular disease, including acute hemodynamic fluctuations and rapid shifts in volume and solute concentration. Home hemodialysis and peritoneal dialysis (PD) may offer benefits in attenuation of cardiovascular disease risk factors primarily through improved volume and BP control, reduction (or slowing progression) of left ventricular mass, decreased myocardial stunning, and improved bone and mineral metabolism. Importantly, although trial data are available for several of these risk factors for home hemodialysis, evidence for PD is limited. Among patients with prevalent cardiovascular disease, home hemodialysis and PD may also have potential benefits. PD may offer particular advantages in heart failure given it removes volume directly from the splanchnic circulation, thus offering an efficient method of relieving intravascular congestion. PD also avoids the risk of blood stream infections in patients with cardiac devices or venous wires. We recognize that both home hemodialysis and PD are also associated with potential risks, and these are described in more detail. We conclude with a discussion of barriers to home dialysis and the critical importance of interdisciplinary care models as one component of advancing health equity with respect to home dialysis.

Exploring kidney dialysis costs in the United States: a scoping review

AIMS

The increasing prevalence of end-stage renal disease (ESRD) in the United States (US) represents a considerable economic burden due to the high cost of dialysis treatment. This review examines data from real-world studies to identify cost drivers and explore areas where dialysis costs could be reduced.

METHODS

We identified and synthesized evidence published from 2016-2023 reporting direct dialysis costs in adult US patients from a comprehensive literature search of MEDLINE, Embase, and grey literature sources (e.g. US Renal Data System reports).

RESULTS

Most identified data related to Medicare expenditures. Overall Medicare spending in 2020 was $29B for hemodialysis and $2.8B for peritoneal dialysis (PD). Dialysis costs accounted for almost 80% of total Medicare expenditures on ESRD beneficiaries. Private insurance payers consistently pay more for dialysis; for example, per person per month spending by private insurers on outpatient dialysis was estimated at $10,149 compared with Medicare spending of $3,364. Dialysis costs were higher in specific high-risk patient groups (e.g. type 2 diabetes, hepatitis C). Spending on hemodialysis was higher than on PD, but the gap in spending between PD and hemodialysis is closing. Vascular access costs accounted for a substantial proportion of dialysis costs.

LIMITATIONS

Insufficient detail in the identified studies, especially related to outpatient costs, limits opportunities to identify key drivers. Differences between the studies in methods of measuring dialysis costs make generalization of these results difficult.

CONCLUSIONS

These findings indicate that prevention of or delay in progression to ESRD could have considerable cost savings for Medicare and private payers, particularly in patients with high-risk conditions such as type 2 diabetes. More efficient use of resources is needed, including low-cost medication, to improve clinical outcomes and lower overall costs, especially in high-risk groups. Widening access to PD where it is safe and appropriate may help to reduce dialysis costs.

System-Level Strategies to Improve Home Dialysis: Policy Levers and Quality Initiatives

Advocacy and policy change are powerful levers to improve quality of care and better support patients on home dialysis. While the kidney community increasingly recognizes the value of home dialysis as an option for patients who prioritize independence and flexibility, only a minority of patients dialyze at home in the United States. Complex system-level factors have restricted further growth in home dialysis modalities, including limited infrastructure, insufficient staff for patient education and training, patient-specific barriers, and suboptimal physician expertise. In this article, we outline trends in home dialysis use, review our evolving understanding of what constitutes high-quality care for the home dialysis population (as well as how this can be measured), and discuss policy and advocacy efforts that continue to shape the care of US patients and compare them with experiences in other countries. We conclude by discussing future directions for quality and advocacy efforts.

Home hemodialysis technique survival: insights and challenges

Home hemodialysis (HHD) offers several clinical, quality of life and cost-saving benefits for patients with end-stage kidney disease. While uptake of this modality has increased in recent years, its prevalence remains low and high rates of discontinuation remain a challenge. This comprehensive narrative review aims to better understand what is currently known about technique survival in HHD patients, elucidate the clinical factors that contribute to attrition and expand on possible strategies to prevent discontinuation. With increasing efforts to encourage home modalities, it is imperative to better understand technique survival and find strategies to help maintain patients on the home therapy of their choosing. It is crucial to better target high-risk patients, examine ideal training practices and identify practices that are potentially modifiable to improve technique survival.

Home dialysis: conclusions from a Kidney Disease: Improving Global Outcomes (KDIGO) Controversies Conference

Home dialysis modalities (home hemodialysis [HD] and peritoneal dialysis [PD]) are associated with greater patient autonomy and treatment satisfaction compared with in-center modalities, yet the level of home-dialysis use worldwide is low. Reasons for limited utilization are context-dependent, informed by local resources, dialysis costs, access to healthcare, health system policies, provider bias or preferences, cultural beliefs, individual lifestyle concerns, potential care-partner time, and financial burdens. In May 2021, KDIGO (Kidney Disease: Improving Global Outcomes) convened a controversies conference on home dialysis, focusing on how modality choice and distribution are determined and strategies to expand home-dialysis use. Participants recognized that expanding use of home dialysis within a given health system requires alignment of policy, fiscal resources, organizational structure, provider incentives, and accountability. Clinical outcomes across all dialysis modalities are largely similar, but for specific clinical measures, one modality may have advantages over another. Therefore, choice among available modalities is preference-sensitive, with consideration of quality of life, life goals, clinical characteristics, family or care-partner support, and living environment. Ideally, individuals, their care-partners, and their healthcare teams will employ shared decision-making in assessing initial and subsequent kidney failure treatment options. To meet this goal, iterative, high-quality education and support for healthcare professionals, patients, and care-partners are priorities. Everyone who faces dialysis should have access to home therapy. Facilitating universal access to home dialysis and expanding utilization requires alignment of policy considerations and resources at the dialysis-center level, with clear leadership from informed and motivated clinical teams.

Cardiovascular Effects of Home Dialysis Therapies: A Scientific Statement From the American Heart Association

Cardiovascular disease is the leading cause of morbidity and mortality in patients with end-stage kidney disease. Currently, thrice-weekly in-center hemodialysis for 3 to 5 hours per session is the most common therapy worldwide for patients with treated kidney failure. Outcomes with thrice-weekly in-center hemodialysis are poor. Emerging evidence supports the overarching hypothesis that a more physiological approach to administering dialysis therapy, including in the home through home hemodialysis or peritoneal dialysis, may lead to improvement in several cardiovascular risk factors and cardiovascular outcomes compared with thrice-weekly in-center hemodialysis. The Advancing American Kidney Health Initiative, which has a goal of increasing the use of home dialysis, is aligned with the American Heart Association's 2024 mission to champion a full and healthy life and health equity. We conclude that incorporation of interdisciplinary care models to increase the use of home dialysis therapies in an equitable manner will contribute to the ultimate goal of improving outcomes for patients with kidney failure and cardiovascular disease.

Peritoneal dialysis in the modern era

The practice and clinical outcomes of peritoneal dialysis (PD) have demonstrated significant improvement over the past 20 years. The aim of this review is to increase awareness and update healthcare professionals on current PD practice, especially with respect to patient and technique survival, patient modality selection, pathways onto PD, understanding patient experience of care and use prior to kidney transplantation. These improvements have been impacted, at least in part, by greater emphasis on shared decision-making in dialysis modality selection, the use of advanced laparoscopic techniques for PD catheter implantation, developments in PD connecting systems, glucose-sparing strategies, and modernising technology in managing automated PD patients remotely. Evidence-based clinical guidelines such as those prepared by national and international societies such as the International Society of PD have contributed to improved PD practice underpinned by a recognition of the place of continuous quality improvement processes.

Utilization of Home Dialysis and Permanent Vascular Access at Dialysis Initiation Following a Structured CKD Education Program

Rationale & Objective

Treatment options for kidney failure are complex, and the majority of patients transitioning to dialysis lack important information about treatment options and are not prepared to make informed decisions about their care. Correspondingly, the majority of patients who start dialysis default to in-center hemodialysis using a central venous catheter for vascular access as the initial modality; furthermore, hospital admissions, mortality, and infections are exceedingly common over the first few months.

Study Design

Matched retrospective cohort study.

Setting & Patients

2,398 adult patients with chronic kidney disease (CKD) who attended a structured CKD education program and pair-matched control patients who did not receive education before starting dialysis between January 2018 and June 2019.

Exposure

CKD education attendance documented from 2 months (60 days)-3 years before dialysis initiation. CKD education consisted of a 1-time, 90-minute, inperson or virtual class.

Outcome

Primary outcomes were dialysis modality and vascular access type on the first day of dialysis (day 0) and at day 90 after dialysis initiation. Secondary outcomes included hospitalizations and deaths during the first year of receiving dialysis.

Analytical Approach

Generalized linear models were used to compare outcomes between patients receiving CKD education and controls.

Results

Compared with controls, CKD education patients were more frequently receiving home dialysis (38.5% vs 12.6%, P < 0.001) and used a permanent vascular access (57.9% vs 33.8%, P < 0.001) at dialysis initiation; differences were minimally attenuated and remained statistically significant at day 90. Hospitalization rates were lower among CKD education patients than among controls during the first year of receiving dialysis (1.00 vs 1.38 admissions per patient-year; P < 0.001). CKD education patients also had lower mortality over the first year of receiving dialysis (P < 0.001).

Limitations

Bias and confounding cannot fully be accounted for in an observational study. Analyses only included patients with commercial and Medicare insurance who received CKD care before dialysis initiation and may not be generalizable to other patient populations.

Conclusions

Our findings indicate that attending a CKD education class before starting dialysis resulted in positive clinical outcomes, including reduction in hospitalization and mortality rates. Broad implementation of structured CKD education may result in more patients choosing home dialysis as their first treatment option and reduce the risk of adverse outcomes in the crucial early period after dialysis initiation.

The availability of support and peritoneal dialysis survival: A cohort study

BACKGROUND

Providing support is important to maintain a patient on peritoneal dialysis (PD), though its impact on outcomes has not been investigated thoroughly. We examined the association between having support and risk of a transfer to hemodialysis.

METHODS

In this retrospective observational cohort study, we used data captured in the Dialysis Measurement Analysis and Reporting system about patients who started PD in Alberta, Canada, between 1 January 2013 and 30 September 2018. Support was defined as the availability of a support person in the home who was able, willing and available to provide support for PD in the patient's residence. The outcome of interest was a transfer to hemodialysis for at least 90 days. We estimated the cumulative incidence of a transfer over time accounting for competing risks and hazard ratios to summarise the association between support and a transfer. We split follow-up time as hazard ratios varied over time.

RESULTS

Six hundred and eighty-three incident PD patients, median age 58 years (IQR: 47-68) and 35% female, were followed for a median of 15 months. The cumulative incidence of a transfer to hemodialysis at 24 months was 26%. Having support was associated with a reduced risk of a transfer between 3 and 12 months after the start of dialysis (HR_3-12mo: 0.44; 95% CI: 0.25-0.78), but not earlier (hazard ratio (HR)_<3mo: 0.96; 95% confidence interval (CI): 0.55-1.69) or later (HR_>12mo: 1.19; 95% CI: 0.65-2.17).

CONCLUSIONS

A transfer to hemodialysis is common. Having a support person at home is associated with a short-term protective effect after the initiation of PD.

From Home Dialysis Access to Home Dialysis Quality

The number and percentage of patients dialyzing at home has steadily increased during the past decade, and federal policy initiatives have driven interest to a new high. However, the mere utilization of home dialysis does not ensure better outcomes for patients and care partners. Although public reporting systems for dialysis quality are mature and robust, the incorporation of home dialysis quality in those systems is immature; the advent of the End-Stage Renal Disease Treatment Choices payment model brings this problem into sharp relief. The home dialysis modalities present both common and unique targets for quality measurement. For both modalities, therapy duration (or its inverse, technique failure) is a potential target. For peritoneal dialysis, peritonitis, catheter complications, and residual kidney function are additional targets; for home hemodialysis, vascular access infections, dialysis adequacy, and treatment adherence are targets. Patient-reported experience measures are also important; this domain is a long-standing disparity, as in-facility hemodialysis patients have been routinely surveyed for several years. The statistical aspect of quality measurement in home dialysis requires some adaptation, as the typical home dialysis program is small, thus presenting a threat to reliability; pooling programs may be necessary. Ultimately, promoting high-quality home dialysis will likely increase utilization of home dialysis.

The ABCs of Kidney Disease: Knowledge Retention and Healthcare Involvement

Low health literacy in the chronic kidney disease population results in lower rates of pre-dialysis preparation and understanding of management to slow progression. The ABCs of Kidney Disease education class provided education in a more consistent manner outside of routine office visits. We aimed to study whether a structured education program would increase kidney disease-specific knowledge and healthcare involvement. Knowledge retention at least 6 months after the class assessed by the Kidney Disease Knowledge Surveys (KiKS) and healthcare involvement based on surveys sent to referring providers were found to have increased. Incorporation of a structured education program would be important for providers to improve long-term knowledge and lead to greater healthcare involvement. Providing an education class outside of the routine office visits will provide a greater impact on health literacy.

Challenges, Facilitators, and Recommendations for Implementation of Home Dialysis in the Veterans Health Administration: Patient, Caregiver, and Clinician Perceptions

Background

Home dialysis confers similar survival and greater quality of life than in-center hemodialysis for adults with ESKD but remains underutilized. We examined challenges and facilitators to implementation of home dialysis and identified stakeholder-centered strategies for improving it.

Methods

We conducted a qualitative, cross-sectional, multisite evaluation that included five geographically dispersed Veterans Health Administration (VHA) home dialysis programs. Participants included patients with ESKD receiving home dialysis, their informal caregivers, and home dialysis staff. Semistructured telephone interviews were conducted and audio-recorded from 2017 through 2018, to assess perceived barriers and facilitators to patient home dialysis use in VHA. Transcribed interviews were analyzed thematically by each participant group.

Results

Participants included 22 patients receiving home dialysis (18 on peritoneal dialysis [PD] and four hemodialysis [HD]); 20 informal caregivers, and 19 home dialysis program staff. Ten themes emerged as challenges to implementing home dialysis, of which six (60%) spanned all groups: need for sterility, burden of home dialysis tasks, lack of suitable home environment, physical side effects of home dialysis, negative psychosocial effects of home dialysis, and loss of freedom. Four themes (40%), identified only by staff, were insufficient self-efficacy, diminished peer socialization, geographic barriers, and challenging health status. Twelve themes emerged as facilitators to implementing home dialysis, of which seven (58%) spanned all groups: convenience, freedom, avoidance of in-center HD, preservation of autonomy, adequate support, favorable disposition, and perceptions of improved health. Two themes (17%) common among patients and staff were adequate training and resources, and physical and cognitive skills for home dialysis. Recommendations to promote implementation of home dialysis common to all participant groups entailed incorporating mental health care services, offering peer-to-peer coaching, increasing home visits, providing health data feedback, and reducing patient burden.

Conclusions

Stakeholder-centered challenges were rigorously identified. Facilitators and recommendations can inform efforts to support home dialysis implementation.

International Society of Nephrology Global Kidney Health Atlas: structures, organization, and services for the management of kidney failure in North America and the Caribbean

The International Society of Nephrology established the Global Kidney Health Atlas project to define the global capacity for kidney replacement therapy and conservative kidney care, and this second iteration was to describe the availability, accessibility, quality, and affordability of kidney failure (KF) care worldwide. This report presents results for the International Society of Nephrology North America and the Caribbean region. Relative to other regions, the North America and Caribbean region had better infrastructure and funding for health care and more health care workers relative to the population. Various essential medicines were also more available and accessible. There was substantial variation in the prevalence of treated KF in the region, ranging from 137.4 per million population (pmp) in Jamaica to 2196 pmp in the United States. A mix of public and private funding systems cover costs for nondialysis chronic kidney disease care in 60% of countries and for dialysis in 70% of countries. Although the median number of nephrologists is 18.1 (interquartile range, 15.3-29.5) pmp, which is approximately twice the global median of 9.9 (interquartile range, 1.2-22.7) pmp, some countries reported shortages of other health care workers. Dialysis was available in all countries, but peritoneal dialysis was underutilized and unavailable in Barbados, Cayman Islands, and Turks and Caicos. Kidney transplantation was primarily available in Canada and the United States. Economic factors were the major barriers to optimal KF care in the Caribbean countries, and few countries in the region have chronic kidney disease-specific national health care policies. To address regional gaps in KF care delivery, efforts should be directed toward augmenting the workforce, improving the monitoring and reporting of kidney replacement therapy indicators, and implementing noncommunicable disease and chronic kidney disease-specific policies in all countries.

Prognostic significance of peritoneal dialysis effluent mitochondrial DNA level

BACKGROUND

Mitochondrial DNA (mtDNA) resembles bacterial DNA and potentially triggers local and systemic inflammation. We evaluate the prognostic implications of PD effluent mtDNA level in peritoneal dialysis (PD) patients.

METHODS

We measured mtDNA in the PD effluent (PDE) sediment and supernatant of 168 incident PD patients. All patients were followed for hospitalization, technique and overall survival.

RESULTS

The median PD effluent supernatant and sediment mtDNA levels were 255.4 unit (interquartile range [IQR] 157.5-451.3) and 201.6 unit (IQR 147.8-267.3), respectively. Serum C-reactive protein level closely with PDE sediment mtDNA level (r = 0.471, p < 0.001) and less with supernatant mtDNA level (r = 0.156, p = 0.044). PDE supernatant mtDNA level correlates with dialysate-to-plasma creatinine ratio at 4 h (D/P4) (r = 0.361, p < 0.001) but not with any clinical outcome. PDE sediment mtDNA was an independent predictor of technique survival (p = 0.011) and the duration of hospitalization (p = 0.044) after adjusting for clinical confounding factors.

CONCLUSIONS

PDE sediment mtDNA level significantly correlated with systemic inflammation, while PDE supernatant mtDNA level correlated with peritoneal transport. PDE sediment mtDNA level also independently predicted technique survival and duration of hospitalization. The mechanism of the different implications between PDE sediment and supernatant mtDNA levels deserves further investigations.

Simultaneous catheter removal and reinsertion, is it acceptable in M. abscessus exit site infection?

In recent times, increasing reports of exit site infections (ESI) in peritoneal dialysis (PD) patients related to environmentally acquired atypical organisms, such as nontuberculous mycobacterium (NTM), have been reported in the literature. Among these NTM, Mycobacterium abscessus (M. abscessus) is unique and is associated with high morbidity and treatment failure rates. The international society of PD guidelines suggests individualizing therapeutic options for NTM-related ESI. Moreover, the guidelines encourage simultaneous catheter removal and reinsertion (SCRR) in isolated ESI, not responding to antimicrobial therapy to avoid PD interruptions. Physicians should be aware of the limitations of such approaches as delay in appropriate PD catheter intervention can be fraught with complications in patients with M. abscessus ESI. We report an M. abscessus ESI in a PD patient who underwent SCRR in conjunction with targeted antimicrobial therapy, and developed M. abscessus peritonitis requiring PD catheter removal and conversion to hemodialysis. The patient also developed ESI at the new exit site long after the PD catheter was removed, requiring prolonged antimicrobial therapy. Our case, taken together with available published case reports, highlights the futility of the SCRR approach towards the M. abscessus ESI and makes the cases for early PD catheter removal in these patients.

Depression and psychosocial burden among caregivers of children with chronic kidney disease

Background

More attention has recently targeted families of children with chronic kidney diseases displaying depressive symptoms and major psychosocial burden due to the long-standing nature of the illness and its alarming complications. A cross sectional comparative study was conducted to assess the rate of occurrence of both depression severity and psychological burden, personal and role strain in a sample of Egyptian caregivers of children with chronic kidney disease.

Results

Thirty caregivers of children with CKD were enrolled compared to 30 matched controls during a 6-month period. A short pre-designed sheet including socio-demographic data, and general medical, psychiatric and family history was used, and Beck Depression Inventory, Zarit Burden Interview, Holmes and Rahe Socioeconomic Stress Scale, and Occupational Stress Questionnaire were answered.

More than half of the caregivers of children with chronic kidney disease reported moderate depression (53.3%), while 30% and 16.7% reported mild and severe depression respectively. The majority of cases 80% had moderate psychological burden. And 70% of cases reported minimal socioeconomic stress compared to 40% in the control. Logistic regression analysis showed that ZBI and SRRS scores were significantly linked to depression and burden found in caregivers of children with CKD (P = 0.001 and 0.031) respectively.

Conclusion

The rate of occurrence of depression and psychological burden is significantly high in caregivers of children with chronic kidney disease; therefore, this population must be assessed and provided with liaison psychological rehabilitation.
