Severe hypercalcaemia remains rare in current practice in our survey: 50% ( I n i = 114) of the respondents managed <5 patients with severe hypercalcaemia per year, 38% ( I n i = 85) managed 5-10 patients and 12% ( I n i = 28) managed >10 patients. Through our survey, ManagEment of hyperCALcemia in Intensive Care (MECALICA), promoted by the Club des Jeunes Néphrologues (French Young Nephrologists Association), we sought to determine how physicians are defining severe hypercalcaemia and how they manage these patients. A total of 51% ( I n i = 116) of the physicians believed that there is a biological threshold for cardiac monitoring in case of hypercalcaemia and 42% ( I n i = 96) had patients who experienced cardiac arrhythmia due to hypercalcaemia (Fig. [Extracted from the article]
