Background
Staphylococcus Aureus (SA) causes a significant proportion of Peritoneal dialysis (PD) associated infections. Patients with nasal carriage of SA are four times more likely to develop PD catheter exit site infections, which can lead to peritonitis. Mupirocin has been used to treat SA nasal carriage.
Methods
We did a retrospective study to see if patients receiving PD in our department were being monitored for SA carriage with nasal swabs, every 3 months as per department policy and the impact it had on PD associated infections (PDAI). The study period was 2.5 years and electronic data base was used to capture information. Timing of nasal swabs and any PDAI were captured.
Results
60 patients were analysed during the study period. The mean age72+/-4 years. 23 patients received 3 monthly nasal swabs to identify SA carriage( group 1). The rest had swabs done at median time of 4 months (4-17 months) ( group 2). 29 patients during this study period developed PDAI. There were 26 peritonitis episodes and 23 exit site infections. The relative risk of developing PDAI with a positive nasal swab was 1.5 (odds ratio of 2.34). Patients in group 1 who had 3 monthly monitoring and appropriate treatment with mupirocin (n= 8) developed PDAI and in group 2 the incidence was (n= 21). Three monthly monitoring for nasal carriage of SA reduced risk of PDAI by 22%.
Conclusion
Patients on PD should have regular and timely monitoring for nasal SA carriage. This may reduce the incidence of PDAI.
