Overview of Design, Methods and Data Collection Centers in SEARCH Phase 3 will continue to conduct population-based ascertainment of
cases of diabetes in youth less than 20 years of age in the year of diagnosis for the period
2010 - 2014, using methods consistent with those employed in SEARCH Phase 1 and
SEARCH Phase 2. This will involve identification, validation, confirmation of eligibility
and uniqueness of cases, and registration of the case both locally with identifiers and
centrally with the SEARCH 3 Coordinating Center (CoC) without identifiers. The 2010 -
2014 cases will have their medical records abstracted and will be asked to complete a
brief survey. A sample of 2012 cases will be invited to an in-person research visit. Case
registration will proceed without disruption in the transition from the end of SEARCH
Phase 2 (September 29, 2010) until the full implementation of the SEARCH Phase 3
protocol. All data collection will be performed under standardized protocols by centrally
trained and certified staff.
