A decade ago CREATION.co introduced a new group of online medical influencers who were impacting the views and behaviours of physicians, policymakers, and patients: Digital Opinion Leaders.
The precise definition of a Digital Opinion Leader (DOL) depends on what you see as important, this will affect which DOLs are relevant to you. We are specialists at asking the right questions so that we can identify those key influencers who are in line with your specific objectives.

By definition, there are significant differences between traditional Key Opinion Leaders, active online KOLs and Digital Opinion Leaders:
HCP DOLs are driving health policy decisions, defining the views of their online peers, and may be shaping your brand well before your product launches. To identify the right DOL for you, you need to answer these questions:
Just as with your interactions with traditional Key Opinion Leaders (KOLs), it is important to remember that your Digital Opinion Leaders are also people. For effective and long lasting DOL engagement you need to:
If you are thinking about implementing a DOL engagement strategy, you need to start with the big picture in mind. Our first recommendation is to include your legal and compliance team. If they start the journey at the beginning there is a bigger chance they will carry the vision.

What (or who) exactly is a Digital Opinion Leader?
By Daniel Ghinn
At CREATION.co, we’ve led the way in using data science to identify and profile healthcare professional Digital Opinion Leaders since we first introduced the concept in 2012.
Deciding how to identify, profile and engage DOLs is a process as unique as your own goals. So we work with you to define what’s most important in your particular DOL identification and profiling exercise.
Below is an illustration of 10 of our metrics to identify your DOLs.

We have been helping pharmaceutical companies with their HCP engagement strategies for the past 20 years. Based on our experience and expertise, here are our top 3 ideas on how to best engage with your HCP Digital Opinion Leaders:
For the rest of our list, check out our HCP engagement strategies article.
Once you have identified your Digital Opinion Leaders, you need to consider how to engage effectively with them. However, before you start thinking about identifying DOLs, you need to put this into context with your long-term goals and think about what would make a Digital Opinion Leader for you. You need to consider:
If you start by answering these, and other strategic DOL questions, you will have a much clearer picture of what a perfect DOL would look like for your business.
Remember, there is no single set of metrics that defines DOL impact. Individual pharma companies should design goals that reflect outcomes aligned with their business objectives. As well as ensuring those objectives also align with the goals of the DOL and, in some cases, the patient community.
At CREATION.co, we spend time ensuring those objectives have been discussed and with a pre-qualified database of nearly 3 million global HCP social media profiles, we can adjust our metrics to ensure the DOLs we identify are the right ones to support your goals.
DOLs suitable for marketing or commercial teams might look different to those suitable for the medical teams. CREATION.co have therefore identified a subset of Digital Opinion Leaders – Digital Scientific Leaders (DSLs). DSLs are HCPs who possess all the qualities of a DOL but have a specific focus and influence in the scientific conversation within the therapy area.
DSLs are driving the discussion around latest study and trial data, testing and diagnosis, and mechanism of action of treatments. In other words, they have a natural inclination to lead and shape the scientific dialogue amongst their peers online. They usually have higher scientific credentials and use their media for peer learning, education, and collaboration.

DOLs are already regulated, in the sense that their behaviour as professionals is governed by their respective professional bodies. In the UK, for example, the General Medical Council (GMC), which governs medical doctors, has provided guidance for doctors on their use of social media since 2013. While controversial among some doctors, the guidance forbids doctors from anonymity on social media.
Furthermore, and relevant to the role of DOLs, the GMC guidance requires doctors to declare any commercial or financial interests in pharmaceutical companies: “When you post material online, you should be open about any conflict of interest and declare any financial or commercial interests in healthcare organisations or pharmaceutical and biomedical companies.”
