BackgroundThe low prevalence of peritoneal dialysis (PD) (9%) vs. hemodialysis (HD) (88.2%) is partly due to patient dropout from therapy.MethodsThis retrospective study identified patients who withdrew from PD between 2016 and 2018 in our program. We evaluated all other factors as controllable losses. Analysis included time on therapy at dropout (very early, early or late) and method of initiation (HD to PD conversion, unplanned PD, or planned start).ResultsEighty-three patients enrolled into our PD program. 27 dropped out; 24 were due to controllable factors, 3 due to death, with a median age at dropout of 52 years old. We determined psychosocial factors (PF) to be the largest controllable factor influencing dropout; contributing a 63% rate among all controllable factors. When considering time until dropout, 100% of very early dropout patients and 50% of late dropout patients did so due to PF. Among early dropout patients 67% dropped out due to other medical reasons. The mean time to dropout for PF, other, and infection (INF) were 13, 26, and 33 months, respectively. When considering type of initiation, we found PF to be the largest attributable factor with 50% of unplanned, 100% of planned, and 50% of conversions stopping therapy.ConclusionsOur study indicates that the primary reason for controllable loss from therapy was secondary to PF regardless of the time on therapy or the method of initiation to therapy.Copyright © 2020 Southern Society for Clinical Investigation.
