RESEARCH

The aims of this study are (1) to ascertain prevalent diabetes cases in calendar year 2017 among youth age <20 years at diagnosis, using cost-efficient approaches that maximize use of information in the electronic health records (EHRs) and administrative databases, (2) to continue to ascertain newly diagnosed (incident 2015-2020) diabetes cases in youth age <20 years, using cost-efficient approaches that maximize use of EHRs and administrative databases, (3) to determine agreement between the etiological classification of diabetes type using biochemical markers and provider assessment; to describe selected clinical characteristics at diagnosis, and to establish an infrastructure that facilitates the development of more detailed ancillary studies by storing biological samples and preserving contact with potential study participants, and (4) To optimize efficiency of SEARCH surveillance activities through targeted Development and Validation (D&V) Projects designed to utilize electronic health data to operationalize each of the three tiers of surveillance to the extent possible.
