The term in the HITECH Act that sets out requirements to be implemented in three stages over a five-year period (2009–2014) for health care providers to be able to show that they're using EHRs in ways that are measurable to show the quality and quantity of adoption of the technology. Some meaningful use criteria are electronic prescribing (e-prescribing), maintaining an up-to-date problem list of patients’ current and active diagnoses, keeping current lists of patients’ medications and medication allergies, and giving patients a clinical summary of all office visits.
