A Spanish multicentric study to evaluate the clinical activity of nephrology fellows during in-hospital on-call shifts.

Background: Nephrologists develop their work in diverse scenarios. A training programme must qualify trainees to assist different kinds of problems. The aim of this study was to characterize patients and pathologies that Spanish nephrology fellows face while on-call.

Methods: This is a descriptive study with clinical and demographic data gathered with a form by 10 nephrology fellows of five university hospitals of Madrid (Spain), throughout their in-hospital 24 h on-call shifts in February and March 2013.

Results: We collected 409 episodes over 338 patients, through 72 shifts. Among these, 16.7% had previous normal renal function, 24.6% chronic kidney disease, 39.5% were on dialysis and 18.2% had a kidney transplant. Most of the consults came from the emergency room (35.9%) or the previous on-call team (13.7%). Afterwards, the most usual destiny was admittance to a nephrology department (32.8%) or discharge (20.5%). The most frequent reason for consulting was a decline in renal function (31.6%) and the second motive an infection. Thirty-four episodes (8.3%) were related to dialysis access problems. Medical treatment was prescribed in 79.2% of the cases, primarily fluids (47.2%) and antibiotics (42.2%). The fellow had to place a central venous catheter in 24 cases (5.9%). Renal replacement therapy was prescribed in 19.8% of the episodes.

Conclusions: Specific renal reasons for consulting nephrologists are common, such as acute kidney injury or dialysis access complications. These patients benefit from a specialized approach to their problems. Clinical activities during in-hospital out-of-hours shifts are a priceless tool as part of the training programme of nephrology fellows.
