Urgent-Start Peritoneal Dialysis: Brazilian Experience.

INTRODUCTION: Unplanned peritoneal dialysis (PD) is an important option for chronic kidney disease (CKD) patients requiring kidney replacement therapy urgently as it offers the convenience of home-based therapy. The objective of this study was to assess the Brazilian urgent-start PD program in three different dialysis centers where there is shortage of hemodialysis (HD) beds. METHODS: This prospective, multicentric cohort study included incident patients with stage 5 CKD and no permanent vascular access established who started urgent PD between July 2014 and July 2020 in three different hospitals. Urgent-start PD was defined as initiation of treatment up to 72 h after catheter placement. Patients were followed up from catheter insertion and assessed according to mechanical and infectious complications related to PD, patients, and technique survival. RESULTS: Over 6 years, 370 patients were included in all three study centers. Mean patient age was 57.8 ± 16.32 years. Diabetic kidney disease was the main underlying condition (35.1%) and uremia was the main cause for dialysis indication (81.1%). Concerning complications related to PD, 24.3% had mechanical complications, 27.3% had peritonitis, 28.01% had technique failure, and 17.8% died. On logistic regression, hospitalization (p = 0.003) and exit site infection (p = 0.002) were identified as predictors of peritonitis, while mechanical complications (p = 0.004) and peritonitis (p < 0.001) were identified as predictors of technique failure and switching to HD. Age (p < 0.001), hospitalization (p = 0.012), and bacteremia (p = 0.021) were observed to predict death. The number of patients on PD increased at least 140% in all three participating centers. CONCLUSION: PD is a feasible option for patients starting dialysis in an unplanned manner and may be a useful tool for reducing shortage of HD beds.

Unplanned vs. planned peritoneal dialysis as initial therapy for dialysis patients in chronic kidney replacement therapy.

AIM: To compare infectious and mechanical complications, technique failure and mortality of a planned PD vs. an unplanned PD program. DESIGN: It was a prospective observational study that included chronic kidney disease (CKD) patients who started PD according to medical recommendation: group1-planned and group 2-unplanned PD. METHODS: This study evaluated patients who started planned and unplanned PD programs in a teaching hospital from July 2014 to December 2017. RESULTS: A total of 58 patients were included in the planned PD group and 113 in the unplanned PD group. There was difference between the two groups in leak and hospital admissions, that were more frequent in the unplanned PD group. Periods free from exite site infection, peritonitis and mechanical complications were longer in the planned group. Cox regression analysis identified age and the lowest albumin value as factors associated with mechanical complications; peritonitis indicated the presence of ESI and mechanical complications; the change to HD was associated with a younger age, mechanical complications, diabetes mellitus (DM) and peritonitis. The factors associated with death were age and lower values of albumin. After 48 months, the growth of the PD program was 252%. CONCLUSION: The technique survival and patient mortality in unplanned PD was similar to planned PD, while the period marked by the absence of complications related to PD was longer in the planned PD group. In the Cox regression, unplanned PD was not identified as risk factor for death, transition to HD or complications related to therapy, while age and lower albumin values were predictors of negative outcomes. IMPACT: Unplanned PD is not risk factor for death and complications related to PD and can be an option to unplanned HD.

Peritoneal Dialysis as an Urgent-Start Option for Incident Patients on Chronic Renal Replacement Therapy: World Experience and Review of Literature.

Chronic kidney disease is a significant problem of public health worldwide, and up to 60% of patients start dialysis in an unplanned manner without a definitive dialysis access. Recently, peritoneal dialysis (PD) has emerged as an alternative to unplanned chronic dialytic method, and the world collective experience shows that PD can be an efficient, safe, and cost-effective alternative with comparable outcomes to the planned PD and urgent-start hemodialysis (HD). More importantly, as compared to urgent-start HD using a central venous catheter, urgent-start PD has significantly fewer incidences of catheter-related bloodstream infections, dialysis-related mechanical complications, and need for dialysis catheter reinsertions during the initial time of the therapy. An integrative review was conducted on PD urgent start compared to HD urgent start and to planned PD, identifying its potential advantages and limitations. Literature search was performed within multiple databases, and observational studies on clinical experience with urgent PD were reviewed and appraised.

Peritoneal dialysis as the first dialysis treatment option initially unplanned / Diálise peritoneal como primeira opção de tratamento dialítico de início não planejado

Abstract Most patients with stage 5 CKD start RRT of unplanned manner. Unplanned dialysis, also known as urgent start, may be defined as hemodialysis (HD) started without permanent vascular access, i.e., using a central venous catheter (CVC), or as peritoneal dialysis (PD) started within seven days after implantation of the catheter, without family training. Although few studies have evaluated the PD as an immediate treatment option for patients starting urgent RRT, theirs results suggest that it is a feasible and safe alternative, with infectious complications and survival similar to patients treated with unplanned HD. Given the importance of the social role of urgent start of dialysis and the lack of studies on the subject, this narrative review aims to analyze and synthesize knowledge in published articles, preferably, from last five years in order to unify information and facilitate future studies.

Resumo A maioria dos pacientes com DRC estádio 5 inicia terapia renal substitutiva (TRS) de modo não planejado. A diálise não planejada, também conhecida como de início urgente, pode ser definida como hemodiálise (HD) iniciada sem acesso vascular definitivo funcionante (utilizando cateter venoso central) ou como diálise peritoneal (DP) iniciada dentro de 7 dias após o implante do cateter. Embora poucos estudos tenham avaliado DP como opção de tratamento imediato em pacientes que iniciam a TRS de modo urgente, seus resultados sugerem que é alternativa viável e segura, apresentando complicações infecciosas e sobrevida semelhantes às dos pacientes tratados por HD não planejada. Tendo em vista a relevância do papel social do início não planejado da TRS e a escassez de estudos sobre o tema, a presente revisão narrativa propõe analisar e sintetizar conhecimentos fragmentados em artigos publicados, no período de 5 anos com o intuito de unificar informações e facilitar estudos futuros.
