Should nephrologists take a larger role in interventional nephrology, and should central line insertion remain a requirement of nephrology residency training? A debate

David C Mendelssohn

The Canadian Society of Nephrology must soon provide input concerning the future of procedural training in nephrology. While at one time, the ability to insert a central venous catheter (CVC) was an essential skill required by all nephrologists, in 2014, nephrology training and practice has changed in fundamental ways such that it would be both unreasonable, and impractical, to maintain this requirement. Indeed, survey evidence suggests that many current trainees are not achieving this competency. Amongst the reasons that this requirement should be withdrawn include: 1) Not all trainees have the procedural skills to safely learn to insert CVC's. 2) Most nephrologists in training and in practice are intellectually oriented, not procedurally oriented and are not seeking to perform lots of procedures. 3) In most practice settings, interventional radiologists and intensive care doctors perform dialysis line insertions using real time ultrasound guidance frequently, and offer timely, safer, and better service to patients. 4) Most trainees will not enter practice settings where CVC insertion ability is required. 5) Otherwise excellent future trainees may be denied a nephrology certificate of special competence only because they are unable to insert a CVC by the end of their fellowship. 6) Academic nephrology training programs that cannot provide adequate CVC insertion experience to fellows may lose their status as training centres. As a pragmatic way forward, Canadian nephrology training programs must encourage and offer only those nephrology trainees who have the ability and interest in procedural nephrology, a pathway through which they may be provided superb advanced training to become an expert. There is no longer a compelling reason to mandate this for all trainees.
