Patient counts
Get counts of de-identified patient data.
UCLA CTSI participates in three networks, i2b2, LADR (Los Angeles Data Repository) and ENACT (Evolve to Next-Gen Accrual to Clinical Trials), that you can use to assess how many patients would meet different study inclusion criteria that are being considered. The systems also help you choose which other institutions to approach for participation if you need a larger sample size. Once your criteria is set, you can also obtain patient counts by gender, race and ethnicity to facilitate the completion of NIH-planned enrollment tables.
