Varas J, et al. - In this multicentre observational retrospective propensity-matched score study, researchers assessed the impacts of cumulative monthly iron doses on mortality and hospitalization in incident haemodialysis patients. As a strategy for maintaining haemoglobin levels in patients that receive haemodialysis, intravenous iron administration was considered advisable. In addition, findings suggested an association of large monthly iron doses, adjusted for body weight, with more hospitalizations, but not with mortality or infection-related hospitalizations.
