Impact of Remote Monitoring on Standardized Outcomes in Nephrology-Peritoneal Dialysis.

Introduction: This study aimed to evaluate the association between the use of remote patient monitoring (RPM) in patients on automated peritoneal dialysis (APD) and the Standardized Outcomes in Nephrology in peritoneal dialysis (SONG-PD) clinical outcomes. Methods: A prospective and multicenter cohort study was conducted on patients with advanced chronic kidney disease on APD, recruited at 16 Spanish Hospitals, between June 1 and December 31, 2021. Patients were divided into 2 cohorts, namely patients on APD with RPM (APD-RPM) and patients on APD without RPM. The primary endpoints were the standardized outcomes of the SONG-PD clinical outcomes: PD-associated infection, cardiovascular disease (CVD), mortality rate, technique survival, and life participation (assessed as health-related quality of life [QoL]). Propensity score matching (PSM) was used to evaluate the association of RPM exposure with the clinical outcomes. Results: A total of 232 patients were included, 176 (75.9%) in the APD-RPM group and 56 (24.1%) in the APD-without-RPM group. The mean patient follow-up time was significantly longer in the APD-RPM group than in the APD-without-RPM group (10.4 ± 2.8 vs. 9.4 ± 3.1 months, respectively; P = 0.02). In the overall study sample, the APD-RPM group was associated with a lower mortality rate (hazard ratio [HR]: 0.08; 95% confidence interval [CI]: 0.01 to 0.69; P = 0.020) and greater technique survival rate (HR: 0.25; 95% CI: 0.11 to 0.59; P = 0.001). After PSM, APD-RPM continued to be associated with better technique survival (HR: 0.23; 95% CI: 0.06 to 0.83; P = 0.024). Conclusion: The use of RPM programs in patients on APD was associated with better survival of the technique and lower mortality rates. However, after PSM, only technique survival was significant.

Dos décadas de análisis de las peritonitis en diálisis peritoneal en Andalucía: aspectos epidemiológicos, clínicos, microbiológicos y evolutivos / Two decades of analysis of peritonitis in peritoneal dialysis in Andalusia: Epidemiological, clinical, microbiological and progression aspects

Antecedentes: Este estudio se centra en la principal complicación asociada a diálisis peritoneal, la peritonitis. Su relevancia deriva de su elevada morbilidad, el efecto negativo que provoca en el peritoneo como membrana de diálisis y de coste económico que ocasiona. Métodos: Estudio observacional de cohortes, analítico, no intervencionista, cuyo objetivo principal es el análisis de las peritonitis en pacientes en diálisis peritoneal, en Andalucía en el periodo: 1 de enero de 1999 a 31 de diciembre de 2017, con un total de 2.904 peritonitis. La base de datos utilizada es la del Sistema de Información de la Coordinación Autonómica de Trasplantes de Andalucía (SICATA). Objetivos: Conocer la evolución de la tasa de peritonitis en nuestra comunidad, analizar datos descriptivos relacionados con los pacientes y las peritonitis, conocer la evolución de estas complicaciones infecciosas y analizar los factores que influyen en estas peritonitis y en su evolución: germen, hospitalización y fecha. Resultados: La tasa de peritonitis ha disminuido progresivamente durante el periodo de estudio desde 0,7 peritonitis por paciente en 1999 hasta 0,33 al final del periodo. La mayoría de las infecciones se tratan de manera ambulatoria (72,5%). Los gérmenes más frecuentes fueron los grampositivos (55,9%), y entre ellos, los estafilococos coagulasa negativos (28,1%). La mayoría de las peritonitis evolucionan a la curación (77,8%). Los factores que influyen de manera significativa en la necesidad de hospitalización y en la evolución de la peritonitis son el germen causal y la presencia de infección del orificio de salida asociado. Conclusiones: En nuestra población, la tasa de peritonitis ha disminuido progresivamente durante el periodo de estudio, alcanzando las recomendaciones de las guías. (AU)

Background: This study focuses on the main complication associated with peritoneal dialysis, peritonitis. Its relevance derives from its high morbidity, the negative effect it has on the peritoneum as a dialysis membrane and its financial cost. Methods: Analytical, non-interventional, observational cohort study, whose main objective is the analysis of peritonitis in patients on peritoneal dialysis in Andalusia from 1 January 1999 to 31 December 2017, with a total of 2,904 peritonitis cases. The database used is the Andalusian Autonomous Transplant Coordination Information System (SICATA). Objectives: To ascertain how the rate of peritonitis is evolving in our community, analyse descriptive data pertaining to patients and peritonitis, ascertain the course of these infectious complications and analyse the factors that influence these cases of peritonitis and their outcomes: germ, hospitalisation and date. Results: The rate of peritonitis decreased progressively during the study period, from 0.7 peritonitis per patient in 1999 to 0.33 at the end of the period. Most infections were treated on an outpatient basis (72.5%). The most common germs were Gram-positive (55.9%), including coagulase-negative staphylococci (28.1%). Most cases of peritonitis progressed to healing (77.8%). The factors that significantly influence the need for hospitalisation and peritonitis progression were the causative germ and associated exit site infection. Conclusions: In our population, the rate of peritonitis decreased progressively during the study period, meeting guideline recommendations. (AU)
