Study of early complications associated with peritoneal dialysis catheters: an analysis of the New Zealand Peritoneal Dialysis Registry data.

Of the 2573 PDC insertions during this period, majority 88% were surgically inserted. The number of complication within 4 weeks ranged from minimum of 20% to a maximum of 34% annually, with infections and flow dysfunctions leading the causes. There has been a minor drop in the infection rates from 19 to 16% (p = 0.21), and flow dysfunction from 12 to 9% (p = 0.16), from 2001 to 2012. A reduced odds of early complication was noted in elderly individuals above 60 years age, with odds ratio of (OR) of 0.73 (95% CI 0.53-0.99), while as higher odds of early complications were recorded in female gender, OR 1.41 (95% CI 1.06-1.88). Of the 10% of patients who failed to initiate PD within 90 days, flow dysfunction contributed to 32%, followed by infectious and surgical causes in 16% and 15%, respectively. The median time from insertion of PDC to initiation of PD was 17 days (interquartile range of 14-24 days) CONCLUSIONS: Improvements in PDC insertion techniques and reduction in infection rates may result in improvements in long-term PD technique survival.
