Underdiagnosis of pediatric hypertension-an example of a new era of clinical research enabled by electronic medical records.

Previously, large scale clinical research required large budgets, significant staff, and long periods of time. Typically most of these resources were spent on data collection to develop electronic research databases. With the proliferation of electronic medical records this clinical research paradigm changes. Here we present a large clinical study of pediatric hypertension (14,187 patients) conducted through an electronic medical record without any budget and within about 70 hours over 6 months.
