Healthwise wins CLINLIFE® 2015 Award

Dear Dr. Onyema,

Developing a new medicine is a tough job that gets more challenging each year. Investigator sites like yours help advance clinical research to change lives. Site performance remains one of the most important factors that impact the successful conduct of a clinical trial.

As part of our first-ever ClinLife® Top Recruiters awards, we recognize sites who achieved outstanding patient recruitment performance in studies supported by ClinLife®, our technology platform that connects and supports sites and patients through enrollment.

We analyzed enrollment data from projects completed in 2015. We selected the top performers based on metrics related to active management of patient referrals, and the resulting number of consented patients generated from Clinlife® referrals.

Congratulations to you and your team on being a part of this elite group of investigator sites! Out of nearly global 2,000 sites worldwide, a small percentage were selected!

Best wishes,

Michael Stadler
