H1 has worked with the top Pharmaceuticals and Life Sciences Companies to help them better understand the HCP Universe. Specifically, H1 clients were seeking to increase MSL engagement. In reviewing the work done across those organizations, H1 uncovered an interesting trend. In companies where Medical Affairs teams engage both the top thought leaders and community treatment leaders; the MSL teams reported approximately 20% more engagements with HCPs as compared to those teams not engaging both types of thought leader. From analyzing H1 user data, we found the most impactful element for establishing community leadership to be the referral data within the HCPs profile.
