Nephrologists-led intervention increases utilisation of peritoneal dialysis in SingaporeLETTER TO THE EDITOR Dear Editor, Over the past decade, the utilisation of peritoneal dialysis (PD) among end-stage kidney disease (ESKD) patients in Singapore has been persistently low (<20%). 1 Difficulty in accessing PD catheter insertion services is considered one of the main obstacles to the growth of the PD population. 2 Traditionally, PD catheter insertion has predominantly been provided by surgeons. Over the last 2-3 decades, there has been a growing trend of nephrologists directly participating in PD catheter insertion. However, interventional nephrology (IN) does not have a well-defined role in peritoneal dialysis (PD) service provision. There are reports and studies on a single "module" of IN practice in the field of PD, such as technical aspects of PD catheter insertion. [3][4][5] More importantly, studies on holistic and multifaceted impacts on ESKD patients are absent, namely, dialysis modality of choice, dialysis service quality improvement and clinical outcomes from the establishment of IN practice. At Khoo Teck Puat Hospital in Singapore, we started IN services for PD in 2015. Here, we report the experience and outcomes of IN practice in PD service from a single centre.This study is a review of our new approach to PD catheter insertion services. We postulated that an IN-led, multidisciplinary collaborative model of care for ESKD patients could improve utilisation and increase PD uptake as a dialysis modality of choice. This approach was based on: interventional nephrologistled PD catheter insertion service by mini-laparotomy; coordination of care by synchronising renal coordinator, nephrologist and anaesthetist visits; and PD initiated by instillation of low-volume peritoneal dialysate (1-1.2L) for the first week, followed by incremental volume adjustment for patients indicated for urgent PD initiation.From January 2011 to June 2020, 201 and 103 PD catheters were inserted by interventional nephrologists and urologists, respectively. All insertions were performed under a mini-laparotomy approach. Both groups had comparable age, ethnicity, body mass index, percentage of diabetes, hypertension, and ischaemic heart disease, while more patients with amputations had PD catheters performed by urologists. Both groups had similar dialysis adequacy.
