Background

Peritonitis is a significant complication among patients undergoing Peritoneal Dialysis (PD). It can lead to significant morbidity, loss of ultrafiltration, permanent membrane damage, and treatment failure. Social aspects including geographical location and educational status have been implicated in the risk of developing peritonitis however no studies have assessed the impact of living space on peritonitis risk. We hypothesize that nephrologists may not offer PD to patients with small living quarters due to a perceived increased risk of peritonitis. This issue is exacerbated in urban populations where most patients live in apartments and not single family homes. Our aim was to determine if home size has any impact on PD peritonitis.

Methods


A retrospective review of prevalent patients undergoing Peritoneal Dialysis between 1998 and 2005 in a single center in an urban population. Inclusion Criteria were all adult patients with complete follow up and housing information for the duration of PD treatment. Data collected for each individual patient included Race, Gender, Age at time of initiation of PD, Presence of Diabetes, BMI, Type of living quarters (House vs Apartment), occurence of Peritonitis and time to first peritonitis or PD discontinuation.

Results

A total of 85 patients met the inclusion criteria and had 35 individual episodes of PD peritonitis. A Univariate Logistic Regression between type of living quarters and Peritonitis had an Odds Ratio 0.53, 95% Confidence Interval, 0.22 to 1.27, p=0.158. We then performed a multivariate logistic regression to control for known independent risk factors for peritonitis including, age, gender, race, diabetes, BMI and residual renal function and found an Odds Ratio 0.48, 95% confidence interval, 0.18 to 1.28. p=0.144. A Cox Regression analysis was then performed to assess the time to peritonitis in relation to living in an apartment with a Hazard Ratio 0.65, 95% confidence interval 0.33 to 1.24, p= 0.186.

Conclusion


To our knowledge this is the first study to examine the effect of living quarters on PD peritonitis in an urban population. Our data suggests that there is no increased risk of peritonitis based on living quarters and should not be a contraindication for PD.
