Background
Peritoneal dialysis (PD)-associated peritonitis is a leading cause of technique failure and transition to hemodialysis. In the Optimizing Peritonitis Prevention in The United States (OPPUS) study, we explored the impact of various patient, facility and treatment factors on the likelihood of cure following a peritonitis episode.
Methods
Using Peritoneal Dialysis Outcomes and Practice Patterns Study phase 1 (2014-2017) data from Australia and New Zealand, Canada, Japan, Thailand, the UK, and the US, cure was defined as the absence of a peritonitis relapse or recurrence, PD catheter removal, transition to hemodialysis or death during the 50 days following a peritonitis episode. Multivariable logistic regression was used to test associations between cure and patient, facility, and treatment characteristics.
Results
We identified 1677 peritonitis episodes in 1190 patients across 126 facilities. Overall, 63% of episodes resulted in a cure. Cure was associated with APD (OR v. CAPD=1.35, 95% CI 1.02-1.80), higher serum albumin (OR=1.04 per 0.1 g/dL, 95% CI=1.01, 1.06), facility icodextrin use (OR=1.06 per 10% greater icodextrin use, 95% CI = 1.01-1.12), and aminoglycoside use for Gram-negative peritonitis (OR v. ceftazidime=3.10, 95% CI=1.02, 9.36). Prior peritonitis (OR v. no prior peritonitis episodes during follow-up=0.84, 95% CI=0.74, 0.97) and concomitant exit-site infection (OR= 0.42, 95% CI=0.28, 0.63) were associated with lower cure odds. Higher odds of peritonitis relapse were seen among patients with greater residual urine volume (OR= 1.14 per 200 ml, 95% CI=1.07, 1.22).
Conclusion
Different characteristics and management practices can impact the likelihood of cure following a peritonitis episode. Our findings can inform future guidelines in addressing the effect of different modifiable patient, facility, and treatment factors on reducing morbidity associated with PD peritonitis.
