AbstractEpidemiological studies in the general population show that the level of dietary salt intake is associated with increases in blood pressure, cardiovascular events and mortality. Trial data show that reducing salt intake reduces blood pressure, cardiovascular events and mortality. On the basis of this evidence, the World Health Organization and other bodies recommend restricting salt intake. The association of salt intake with blood pressure and cardiovascular disease is also seen in CKD and trials of salt reduction in CKD have shown benefit by reducing blood pressure and cardiovascular events. However, these trials have typically used resource-intensive approaches to dietary salt reduction that are not suitable for routine clinical care and salt intake typically remains high in people with CKD. The OxSalt care bundle is a low-cost intervention that was demonstrated in the OxCKD1 trial to help people with CKD to lower their salt intake and could be applied in routine clinical practice.
