Interobserver agreement of peritoneal dialysis exit site scoring: Results from the Standardizing Care to Improve Outcomes in Pediatric End Stage Kidney Disease (SCOPE) collaborative.

Whereas interobserver agreement is high when the appearance of a peritoneal dialysis catheter exit site is characterised as 'normal', interobserver disagreement is common when the appearance of the exit site is 'abnormal'. Further work is warranted to improve interobserver agreement of exit site assessments and to identify domains conferring an increased risk of infection.
