Abstract Background There is limited information available on the use of assisted peritoneal dialysis (PD) over time and the impact of economic incentives on its utilization. The aim of this study was to describe the trends in assisted PD utilization and the type of assistance provided. We wanted to estimate if an economic incentive implemented in 2011 in France was associated with an increase in the utilization of nurse-assisted PD. Methods This retrospective, multicentre study, based on data from the French Language Peritoneal Dialysis Registry, analysed 11 987 patients who initiated PD in France between 1 January 2006 and 31 December 2015. Adjusted Cox regression with robust variance was used to examine the initiation of assisted PD, both nurse-assisted and family-assisted, accounting for the nonlinear impact of the PD starting time. Results There were 6149 (51%) incident patients on assisted PD, 5052 (82%) on nurse-assisted PD and 1097 (18%) on family-assisted PD over the study period. In the adjusted analysis, calendar time was associated with the assisted PD rate: it declined from 2008 until 2013 before flattening out and then it increased after 2014. Nurse-assisted PD utilization increased significantly after 2012, whereas family-assisted PD utilization decreased linearly over time (prevalence ratio = 0.94, 95% confidence interval 0.92–0.97). Conclusions The assisted PD rate decreased until 2013, mainly because of a decline in family-assisted PD. The uptake in nurse-assisted PD observed from 2013 reflects the effect of an economic incentive adopted in late 2011 to increase PD utilization.
