When it comes to changing physicians' prescribing behavior, personal influences play a crucial role. It's only natural for doctors to seek opinions from colleagues they know and trust, and with whom they have established personal relationships. Understanding how key opinion leaders (KOL) influence your market is essential. Educational and marketing programs based on KOL studies allow you to accelerate product launches, penetrate high-volume prescriber segments, and reach the prescribers for high-potential patient populations.
