Patients with CKD and ESRD have more co-morbidities, are hospitalized more often and for longer lengths of stay, and incur greater healthcare costs than patients with other chronic conditions. Enhanced hospital to home transitional care interventions have been shown to improve medication information transfer, reduce hospital readmissions, and slow the progression of declining health in the general population of hospitalized patients. What is not known is the impact enhanced transitional care can have for a very high-risk population, such as those with CKD and ESRD. Interventions that prevent or slow CKD progression, i.e. blood pressure control and intensive glycemic control in patients with diabetes, are all highly dependent on meticulous medication management.
