Top 25 organizations with the most digital opinion leaders

Healthcare experts and key opinion leaders (KOLs) live digital lives, like most of us. Life science companies are paying attention to KOLs’ online lifestyles to engage with them more effectively. As a result, many medical device and pharmaceutical companies are reimagining traditional KOL roles as digital influencers, or digital opinion leaders (DOLs).

The rise in telehealth during the COVID-19 pandemic aligned with a shift to more virtual interactions with medical affairs and supply reps at healthcare provider offices. Understanding an expert’s sphere of influence, areas of focus and engagement in their community can help life science companies develop stronger KOL/DOL engagement strategies.

What is a digital opinion leader (DOL)?

Digital opinion leaders, also known as digital influencers, are healthcare providers and medical, scientific or public health experts who engage in digital and social dialogue about scientific, medical and healthcare related topics. Industry analysts, journalists, patient advocates, current or former patients and caregivers can become digital influencers in the healthcare space as well.

DOLs play an increasingly important role in the life sciences and healthcare industries as they represent a new group of external experts who are informing the online discourse about therapeutic areas and other important healthcare topics. Digital influencers communicate quickly and widely without approval processes and reach audiences that might be difficult to access through traditional methods like scientific publications.

DOLs also include rising stars: young medical and scientific experts who show potential to be an influential voice in the industry.
