- Abstract
Aim: Peritonitis is a critical complication in patients undergoing peritoneal dialysis. Patient characteristics, especially conscientiousness, potentially influence self‐care activity. This study aimed to examine the relationship between the peritonitis risk and the patient conscientiousness. Methods: This retrospective observational study was conducted at three Japanese medical centres in 2018. Adult patients undergoing peritoneal dialysis were evaluated for conscientiousness with the Japanese version of the Ten‐Item Personality Inventory. We followed the patients from peritoneal dialysis induction retrospectively on chart review. The primary outcome was time to first episode of peritonitis after initiation of peritoneal dialysis in the entire observation period. Hazard ratios were estimated using a Cox model adjusted for potential confounders. Results: Among 111 patients enrolled, 32 experienced peritonitis. The patients were divided into the more conscientious group (n = 64) and less conscientious group (n = 47) based on a mean conscientiousness score of 3.991. Additionally, less conscientious patients tended to be at higher risk for peritonitis during the entire study period (hazard ratio adjusted for age and sex, 1.99; 95% confidence interval, 0.98–4.03; p =.057). The increased risk in the less conscientious group was statistically significant in the first year (adjusted hazard ratio, 6.98; 95% confidence interval, 1.42–34.40; p =.017). Conclusion: Less conscientious patients significantly have shorter peritonitis‐free survival in the early phase after peritoneal dialysis induction although not significantly during the entire study period. Personality trait assessment using the Ten‐Item Personality Inventory could be helpful in educating and following up patients undergoing peritoneal dialysis. SUMMARY AT A GLANCE: Less conscientious patients have significantly lower peritonitis‐free survival rate in the early phase after PD initiation, which highlights the importance of personality trait assessment to improve patients' awareness during PD training.
