Risk Factors for Peritoneal Dialysis-Associated Peritonitis Due to Home-Based Operation Management: A Retrospective Cohort Study.
Linlin Pan, Mengjia Wang, Qiaoqin Yu and 3 others
PMID 39653686WHAT IT FOUND
In home peritoneal dialysis patients, improper handwashing, not checking povidone-iodine cap expiry and quality, and poor dialysis fluid storage were independent risk factors for peritonitis.
Nurses should retrain these steps, not assume they prevent infection.
Key findings
01Improper handwashing was an independent risk factor for peritonitis, with OR 6.28.
02Not checking the expiration date and quality of the protective cap with povidone-iodine was an independent risk factor for peritonitis, OR 4.34.
03Improper storage of peritoneal dialysis fluid was an independent risk factor for peritonitis, OR 3.85.

What it does not show
Single-centre retrospective design, so results may not apply to other settings. Home-operation data came from questionnaires during visits, so recall and reporting bias are possible. Patients with poor compliance, major comorbidities, mental disorders, multiple peritonitis episodes, haemodialysis or transplant were excluded, which may limit generalisability. Rare behaviours were not analysed, so some possible home-operation risks could not be assessed. Observational associations do not show that changing a behaviour will prevent peritonitis.
Declared interests
The authors declared no conflicts of interest. Funding was provided by a medical and health research project in Zhejiang province and a general natural science research project from the Zhejiang Provincial Department of Education.
The easy way to misread this
Do not conclude that perfect handwashing, cap checking or fluid storage will prevent peritonitis. This study found associations in home dialysis patients, not a tested intervention, and other unmeasured factors may explain the differences.
