“…Theoretically, more experienced nurse trainers should provide more efficient training with good communication and counselling skills, and demonstrate greater sensitivity to patients' physiological and psychological challenges. This tenet is supported by a single-centre, Chinese observational cohort study of 305 incident PD patients [32] (Table 2), which found that patients trained by nurses with more than 15 years of general medical experience had a lower risk of Gram-positive peritonitis compared with patients trained by nurses with between 10 and 15 years' experience [adjusted hazard ratio (HR) 2.69, 95% CI: 1.03-6.98; P = 0.04] or less than 10 years' experience (HR 3.16, 95%CI: 1.20-8.30; P = 0.02). In contrast, another single-centre retrospective study by Chow et al [33] in Hong Kong (Table 2), including 200 PD patients, reported an inverse association between the duration of a PD trainer's experience and peritonitis rates.…”
