Methods, systems, and apparatuses for integrating medical device data are disclosed. In an example embodiment, an integration engine receives infusion therapy progress data from an infusion pump and renal failure therapy progress data from a renal failure therapy machine. The integration engine determines a plurality of different types of infusion parameters, determines a plurality of different types of renal failure therapy parameters, and causes a combination user interface to display the plurality of infusion parameters, the plurality of renal failure therapy parameters, and mathematical operations for selection by an operator. The integration engine enables the operator to create derivative data by receiving a selection of an infusion parameter, a renal failure therapy parameter, and a mathematical operation. The integration engine then causes the combination user interface to display the derivative data in conjunction with the infusion therapy progress data and the renal failure therapy progress data.
