Project Status as of June 2019

STARRT-AKI has recruited well globally and will likely stop recruiting by mid-August 2019, as we have reached more than 99% of the global recruitment target. Data collection will continue with a 3-month follow-up for the primary outcome concluding by 31 December 2019. The secondary outcomes, which include 1-year follow-up, will be sought via data linkage. The data linkage for secondary outcomes will occur in Q3 2020. This has been an extremely successful global collaboration with Australia and New Zealand sites contributing approximately 20% of the global study participants.
