What Separates a High-Enrolling Site from an Average One? (It's Not What You Think)
Ask a sponsor what makes a great clinical trial site, and the answers tend to cluster around the same factors: institutional prestige, physician expertise, patient volume, and a history of prior participation in trials. These things matter. But they don't predict enrollment performance as reliably as most sponsors assume. The sites that consistently enroll at or above projection across different studies, different therapeutic areas, different sponsors share a different set of characteristics. They are operational, not reputational. And understanding them changes how you select sites, how you support them, and how you diagnose underperformance when it occurs.
