Components of A Successful Peritoneal Dialysis Program

Analysis of a nurse-provided on-call peritoneal dialysis support in an outpatient reference care centre

BACKGROUND

To analyse the nature of medical or technical emergency issues of ambulatory peritoneal dialysis (PD) patients calling a nurse-provided emergency PD support service of a reference centre that is provided all year in the after-hours.

METHODS

We retrospectively analysed patients' chief complaint, urgency, resolution of and association to current PD treatment and modality directed to an on-call nurse-provided PD support service from 2015-2021 based on routinely collected health data. Calls were systematically categorized being technical/procedural-, medical-, material-related or type of correspondence. Call urgency was categorized to have "immediate consequence", inquiry was eligible for "processing next working day" or whether there was "no need for further action". Call outcomes were classified according to whether patients were able to initiate, resume or finalize their treatments or whether additional interventions were required. Unexpected adverse events such as patients' acute hospitalization or need for nurses' home visits were evaluated and quantified.

RESULTS

In total 753 calls were documented. Most calls were made around 7:30 a.m. (5:00-9:00; median, 25-75th CI) and 6:30 p.m. (5:00-8:15). 645 calls were assigned to continuous ambulatory- (CAPD) or automated PD (APD). Of those, 430 calls (66.7%) had an "immediate consequence". Of those 77% (N = 331) were technical/procedural-, 12.8% (N = 55) medical- and 6.3% (N = 27) material related issues. 4% (N = 17) were categorized as other correspondence. Issues disrupting the course of PD were identified in 413 cases. In 77.5% (N = 320) patients were able to initiate, resume or finalize their treatment after phone consultation. Last-bag exchange was used in 6.1% enabling continued therapy in 83.6%. In 35 cases a nurse visit at patients' home or patients' visit to the practice at the earliest possible date were required, while hospitalization was required in seven medical category cases (5.4% and 1.09% of total assessed calls, respectively).

CONCLUSION

The on-call PD-nurse provides patient support for acute and imminent issues enabling them to successfully initiate, resume or finalize their prescribed treatment. Nurses triage of acute conditions facilitated rapid diagnostics and therapy. Maintaining quality PD homecare, the provision of trained personnel is indispensable. The information gathered in this study may therefore be used as a foundation to tailor educational programs for nephrology nurses and doctors to further develop their competencies in PD.

Early outcomes of peritoneal dialysis in a middle-income country: A retrospective cohort study of a large dialysis network in Colombia

BACKGROUND

The first year of dialysis is critical given the significant risk for complications following dialysis initiation. We analysed complications during the first year among incident peritoneal dialysis (PD) patients.

METHODS

This retrospective cohort study comprised adult kidney failure patients starting PD in Baxter Renal Care Services in Colombia, receiving their first PD catheter between 1 January 2017 and 31 December 2020 and were followed up for up to 1 year. We analysed incidence, causes and factors associated with complications using logistic regression and transfer to haemodialysis (HD) using the Fine-Gray regression model.

RESULTS

Among 4743 patients receiving their first PD catheter: 4628 (97.6%) of catheter implantations were successful; 377 (7.9%) patients experienced early complications. The incidence rate of complications during the year was 0.51 events per patient-year (95% CI: 0.48-0.54). Age, obesity and urgent start were associated with higher probability of complications after catheter implantation. The cumulative incidence of transfer to HD within 1 year of PD initiation was 10.1% [95% CI: 9.2-11.1%]. The hazard function for transfer to HD showed an accelerating pattern during the first month followed by progressive decrease during the first year.

CONCLUSIONS

In this large population of incident PD patients, there is a high primary catheter placement success rate. Urgent start, age ≥65 years, obesity, centre size ≥150 PD patients and diabetes were risk factors associated with early complications. The follow-up of the cohort from day 1 of PD treatment showed that the risk for transfer to HD was higher during the first month.

Patients and nursing-related factors associated with switching from peritoneal dialysis to hemodialysis: A cross-sectional survey

The study aimed at analyzing patients and nursing-related factors associated with switching from peritoneal dialysis to hemodialysis. A telephone survey with 574 patients receiving care at six peritoneal dialysis centers of the Mexican Institute of Social Security was conducted: 64.3% were on peritoneal dialysis, and 35.7% had transitioned from peritoneal dialysis to hemodialysis. Data were collected on participants' sociodemographic and clinical characteristics, peritoneal dialysis center size, and nursing workload. Descriptive, bivariate, and multiple Poisson regression analyses were performed. Factors associated with an increased probability of switching from peritoneal dialysis to hemodialysis were a history of catheter dysfunction, peritonitis, and being treated in a large peritoneal dialysis center with a low (<50 patients per nurse per month) or high nursing workload (>70 patients per nurse per month) located in the State of Mexico, compared to a medium-size peritoneal dialysis center with a moderate workload (50-70 patients per nurse per month). To decrease the odds of switching from peritoneal dialysis to hemodialysis, improvement programs should aim to limit nurses' workload to 50-70 patients per nurse per month and implement evidence-based nursing interventions to prevent, detect, and manage peritonitis and peritoneal catheter dysfunction.

Evolving peritoneal dialysis care in Chinese mainland from 2010 to 2020: Comparison data from two surveys

INTRODUCTION

Along with the peritoneal dialysis (PD)-favored policy in China and the implementation of more comprehensive PD management, PD has evolved in Chinese mainland over the last decade. Despite the existence of national registries and several provincial epidemiological descriptive studies, there was almost no national research on the changing trajectory in PD population. A comparison study, based on two national surveys that were 10 years apart, was conducted to reveal the evolvement of PD care in Chinese mainland.

METHODS

Two national surveys have been done respectively in 2010 and 2020 to capture the epidemiological status, application of different modalities, management of perioperative infection, and long-term complications among PD patients.

RESULTS

In the study with 730 participating hospitals (n = 14,912 PD patients) in 2010 and 746 hospitals (n = 101,537) in 2020, prevalent PD patients have increased in the past 10 years with increased numbers of PD patients in both secondary (average 5 ± 16 vs. 43 ± 41, p < 0.01) and tertiary hospitals (32 ± 53 vs. 153 ± 215, p < 0.01). Automated PD has been accessible in 0.4% of all hospitals, only in tertiary centers in 2010 and its application increased to 51% in 2020. PD centers have become more engaged in PD catheter placement, treated properly for the PD-related infection, and carried out the follow-up in compliance with the national protocols.

CONCLUSIONS

Our study indicates that over the past decade, the prevalent PD population has quickly expanded with increased APD availability in Chinese mainland. The management of PD patients has become better conforming to the guidelines and long-term follow-up of patients have remained stable. Further studies are warranted to evaluate whether the rapidly changing paradigm of PD could translate into the socio-economic benefits in the society.

Factors Affecting Selection of a Dialysis Modality in Elderly Patients With Chronic Kidney Disease: A Prospective Cohort Study in Korea

Background

We investigated factors associated with the selection of a dialysis modality for elderly patients compared to younger patients.

Methods

This study included 2,514 incident dialysis patients from a Korean multicenter prospective cohort. Multivariate logistic regression analyses were performed with demographic, socioeconomic, and clinical data to analyze factors associated with the chosen dialysis modality. Differences in these factors were compared between the elderly (≥65 years) and younger (<65 years) patients.

Results

Of the enrolled patients, 1,746 (69.5%) and 768 (30.6%) selected hemodialysis (HD) and peritoneal dialysis (PD), respectively. The percentage of PD was higher in younger patients than in elderly patients (37.1 vs. 16.9%, p < 0.001). Multivariate analysis showed that planned dialysis (p < 0.001), employment status (p < 0.001), and independent economic status (p = 0.048) were independent factors for selecting PD, whereas peripheral vascular disease (p = 0.038) and tumor (p = 0.010) were factors for selecting HD in the younger group. In the elderly group, planned dialysis (p < 0.001) and congestive heart failure (CHF; p = 0.002) were associated with choosing PD; however, tumor (p = 0.006) was associated with choosing HD. A two-way ANOVA showed that planned dialysis and CHF showed a significant interaction effect with age on modality selection.

Conclusions

As the age of patients with chronic kidney disease increased, HD was more frequently selected compared to PD. Dialysis planning and CHF interacted with age in selecting dialysis modalities in elderly patients. Elderly patients were less affected by socioeconomic status than younger patients.

The history of peritoneal dialysis in China: past, present and future trends

Peritoneal dialysis (PD) was introduced in China more than 60 years ago and has grown continuously since then. Now China leads the first of the world in number of patients on PD. In this manuscript a brief review of the history of peritoneal dialysis in China is presented; this includes a description of pioneers and their important contributions, discussion of peritoneal dialysate, the technique of the use of Tenckhoff catheter, the use of continuous ambulatory peritoneal dialysis (CAPD) and dialysis registration. Current ongoing PD research activities among Chinese PD academicians are also discussed. Finally, we present four areas of future focus: 1) the promotion of PD in rural areas where PD use is still very limited due to the lack of PD awareness and education; 2) PD quality management and continuous quality improvement (CQI) program particularly focusing on PD adequacy and patient rehabilitation; 3) development and enforcement of national standards on PD management; 4) multi-center studies to compare the benefits of PD and hemodialysis (HD) that should include survival, rehabilitation and cost-effectiveness.

Dietary Adherence, Self-Regulatory Fatigue and Trait Self-Control Among Chinese Patients with Peritoneal Dialysis: A Cross-Sectional Study

PURPOSE

Little is known about factors that predict dietary adherence among Chinese patients undergoing peritoneal dialysis. We investigated whether self-regulatory fatigue and trait self-control influence dietary adherence among Chinese patients with peritoneal dialysis.

METHODS

A total of 192 Chinese patients undergoing peritoneal dialysis were recruited at two peritoneal dialysis centers. The dietary adherence, trait self-control and self-regulatory fatigue of these patients were assessed using self-administered questionnaires. Clinical data were extracted from the hospital medical records. The significance of several social demographic factors on dietary adherence was analyzed using One-way ANOVA was used to analyze, whereas the association between dietary adherence and self-regulatory fatigue as well as trait self-control were analyzed using Pearson correlation. The independence association between dietary adherence and other influencing factors was assessed using Multivariable linear regression analyses.

RESULTS

We found that peritoneal dialysis patients only moderately adhere to dietary prescriptions. The top three least adherences were observed for salt intake (1.89±0.36), face of difficulty (2.86±0.26) and fluid restriction adherence intake (2.97±0.30). Multivariable linear regression analysis revealed that education level (β=0.339, P<0.001), residence (β=-0.151, P=0.015), self-regulatory fatigue (β= -0.648, P<0.001), and trait self-control (β=0.118, P=0.022) were independent predictors of dietary adherence.

CONCLUSION

Education level and residence strongly influence dietary adherence among Chinese peritoneal dialysis patients. On the other hand, Self-regulatory fatigue and trait self-control are independent predictors of dietary adherence among peritoneal dialysis patients. These findings can guide the enhancement of dietary adherence of peritoneal dialysis patients.

Setting Up and Expanding a Home Dialysis Program: Is There a Recipe for Success?

Home dialysis modalities remain significantly underused in the United States despite similar overall survival in the modalities, and recent incentives to expand these modalities. Although the absolute number of patients using home modalities has grown, the proportion compared to in-center hemodialysis (ICHD) continues to remain quite low. Well known barriers to home dialysis utilization exist, and an organized and team-based approach is required to overcome these barriers. Herein, we describe our efforts at growing our home dialysis program at a large academic medical center, with the proportion of home dialysis patients growing from 12% to 21% over the past 9 years. We prioritized individualized education for patients and better training for physicians, with the help of existing resources, aimed at better utilization of home modalities; an example includes dedicated dialysis education classes taught twice monthly by an experienced nurse practitioner, as well as the utilization of the dialysis educator from a dialysis provider for inpatient education of patients with CKD. The nephrology fellowship curriculum was restructured with emphasis on home modalities, and participation in annual home dialysis conferences has been encouraged. For timely placement and troubleshooting of access for dialysis, we followed a complementary team approach using surgeons and interventional radiologists and nephrologists, driven by a standardized protocol developed at UAB, and comanaged by our access coordinators. A team-based approach, with emphasis on staff engagement and leadership opportunities for dialysis nurses as well as collaborative efforts from a team of clinical nephrologists and the dialysis provider helped maintain efficiency, kindle growth, and provide consistently high-quality clinical care in the home program. Lastly, efforts at reducing burden of disease such as decreased number of monthly visits as well as using innovative strategies, such as telenephrology and assisted PD and HHD, were instrumental in reducing attrition.

Changes in Outcomes over Time Among Incident Peritoneal Dialysis Patients in Southern China

Background:The present study was to investigate the changes in outcomes of incident patients who started peritoneal dialysis (PD) between 2006 - 2010 and 2011 - 2015 in Southern China.Methods:In this single-center cohort study, incident PD patients from January 1, 2006, to December 31, 2015, were enrolled. Collected data included baseline demographic, clinical, biochemical characteristics, and outcomes. Patients who initiated PD during 2006 - 2010 and 2011 - 2015 were followed up until December 31, 2011, and December 31, 2016, respectively. Peritonitis rate, patient survival, and technique survival were compared between the 2 incident cohorts.Results:A total of 2,021 incident PD patients were enrolled, with a mean age of 47.2 ± 15.2 years, 40.6% female. Compared with the 2006 - 2010 cohort (n = 1,073), patients initiating PD during 2011 - 2015 (n = 948) were younger (46.2 ± 14.8 vs 48.1 ± 15.5 years, p = 0.006), had similar baseline estimate glomerular filtration rate (eGFR) (5.81 ± 2.41 vs 5.81 ± 2.89 mL/min/1.73 m², p = 0.109) and comparable percentage of diabetes mellitus (24.9% vs 25.7%, p = 0.682). The overall peritonitis rate in the 2011 - 2015 cohort was lower than in the 2006 - 2010 cohort (0.158 vs 0.161 episodes per year, p = 0.001). At the end of 1, 3, and 5 years, the 2006 - 2010 and 2011 - 2015 cohorts had patient survival rates of 94%, 82%, 64%, and 97%, 87%, 74%, respectively (p < 0.001). After multivariable adjustment, patients starting PD in 2011 - 2015 were associated with lower risk of all-cause mortality (hazard ratio [HR] 0.77, 95% confidence interval [CI] 0.60 - 0.98). In gender and age-stratified models, male patients had a significantly lower risk of all-cause mortality (HR 0.58, 95% CI 0.41 - 0.83), and patients with age < 65 years showed a significantly lower risk of cardiovascular (CV) mortality (HR 0.63, 95% CI 0.40 - 0.99) in 2011 - 2015 compared with 2006 - 2010. The death-censored technique survival rates were not significantly different between the 2 cohorts (p = 0.234).Conclusion:Peritonitis rates and patient survival on PD continue to improve. Patients initiating PD between 2011 and 2015 were associated with better outcomes.
