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 related to a patient identifier and receives renal failure therapy progress data from a renal failure therapy machine related to the same patient identifier. The integration engine determines fluid balance data based on a difference between at least some of the infusion therapy progress data and at least some of the renal failure therapy progress data and causes a combination user interface to display a trend of the fluid balance data within a fluid balance timeline. The integration engine determines when the trend of the fluid balance data exceeds a fluid balance limit and causes a fluid balance alarm or alert to be provided.
