Abstract

Peritoneal dialysis (PD)-related peritonitis is one of the top priorities for care and research among PD stakeholders. This study summarizes PD peritonitis rates from available population-based national or regional registries around the world, examining trends over time. This is a systematic review of PD peritonitis rates in patients treated with PD for kidney failure, from census-based national or provincial/statewide/provider registries or databases. MEDLINE (via PubMed) was searched from inception to August 2020, and inquiries made to national registry personnel using the International Comparisons section of the 2018 United States Renal Data System Annual Data Report as a contact list. Quantitative synthesis was done using weighted random-effects Poisson regression. Of 81 countries that reported utilization of PD, 19 did not have a traditional dialysis registry (governed by either professional societies or government entities), and only 33 monitored PD peritonitis rates correctly and accessibly. There is wide variation in PD peritonitis rates between countries, although the global average has been decreasing over time, from 0.600 episodes/patient-year in 1992 to 0.303 in 2019. Other sources of variability include the continent in which the country is nested and the size of its PD population. PD peritonitis, despite its importance for PD stakeholders, is under-monitored. While the global rate is decreasing over time, the presence and extent of this improvement varies from country to country. There is an opportunity for better monitoring, research into underachieving and overachieving nations and development of international clinical support networks.
