The effect of hand fine motor skills on peritoneal dialysis-related peritonitis

Introduction: We aimed to evaluate the relationship between the hand fine motor skills of peritoneal dialysis (PD) practitioners and PD-related peritonitis. Methods: This multicenter prospective observational study was conducted with 120 incident PD patients. Patients were divided into two groups who had PD-related peritonitis within the first year as Group 1, and those who did not as Group 2. Hand fine motor skills were evaluated by Nine-Hole Peg Test (NHPT) and Nut Screwing Test (NST). Results: Initial NHPT (28.5 ± 6.0 s vs. 25.8 ± 5.0 s, p = 0.011) and NST (82.3 (61.5–102.8) s versus 65.3 (52.3–88.5) s p = 0.023) scores were significantly higher in Group 1 than Group 2. In multivariate logistic regression analysis, NHPT, Body Mass Index, Mini-Mental Test, self PD practitioner, and catheter complications were found to be independent variables in predicting PD-related peritonitis. Conclusion: Decreased hand fine motor skills of PD patients is a risk factor for peritonitis.
