KOL profiling is the work of building and keeping a documented record of a key opinion leader's expertise, research, roles, and influence, so a medical affairs team can decide whether, why, and how to engage that expert. A profile is the file behind the name. It holds what the person has published and studied, where they practice and teach, which committees and societies they sit on, who they work with, and how they communicate. Teams build profiles after they have found the experts and before they rank them or plan a relationship.
Quick answer: A KOL profile records an expert's background, scholarly work, roles, collaborators, and online presence, with sources and dates. It sits between identification, which finds candidate experts, and tiering, which ranks them. A good profile supports engagement decisions on documented expertise, which is also what industry codes expect when a company selects an HCP for paid work.
Where profiling fits
The terms around key opinion leaders are often used as if they meant the same thing. They describe four separate steps.
Identification finds the candidates, usually by searching publications, trial records, congress programs, and guideline panels for a disease area. Profiling builds a record for each candidate that is worth a closer look. KOL tiering ranks the profiled experts and maps the networks between them. Engagement planning decides what the medical team will do with each one, and an MSL carries out that plan.
Each step depends on the one before it. A tier assigned without a profile behind it is a guess, and a profile nobody reads before planning a visit is wasted work.
What a KOL profile holds
Profiles vary by company and therapeutic area, but most include the same kinds of information:
- professional background: specialty, training, current institution and appointments, and practice setting
- scholarly work: publications and where they appeared, clinical trial roles, grants, and invited presentations
- positions of influence: guideline committees, society leadership, editorial boards, and formulary or pathway committees
- collaborators: co-authors, co-investigators, and the institutions they work with most
- online presence: whether the expert is also a digital opinion leader, what they post about, and who engages with it
- scientific interests: the questions the expert is working on or has raised, in their own words where possible
- history with the company: past interactions, advisory roles, and contracted work
Each entry should carry its source and the date it was checked. An expert who changed institutions last year, or whose last trial closed five years ago, can look very different on an old profile than they do today.
What a profile should not drive
A profile built for medical affairs describes scientific standing. It should not be used to pick experts for paid work because of how much they prescribe. The HHS Office of Inspector General's 2020 Special Fraud Alert on speaker programs lists choosing HCPs based on past or expected revenue from their prescribing, including return-on-investment analysis, among the signs of a suspect program.
The PhRMA Code points the other way. It says the criteria for selecting a consultant should relate directly to the purpose of the work, and the people selecting should have the expertise to judge whether an HCP meets them. A profile that documents expertise is how a team shows that standard was met. It also supports the tier that sets the expert's fair market value rate.
Profiles also hold personal data. Data protection laws such as the GDPR in Europe apply to what is collected, how long it is kept, and who can see it, so the profile should contain what the team needs and no more.
Keeping profiles current
Influence changes. A new trial readout, a guideline seat, or a move to a new institution can raise an expert's standing within months, while others step back from research. Teams that profile once and never revisit end up planning visits around a list that is out of date. Most refresh profiles on a schedule and whenever an MSL reports a change after a meeting.
Much of the raw material is public but scattered across journals, trial registries, congress programs, and social platforms. TikaMobile's KOL identification brings an expert's background, publications, trials, presentations, grants, collaboration networks, and social media activity into one profile.
Frequently asked questions
What is KOL profiling?
KOL profiling is building a documented record of a key opinion leader's expertise, research, roles, collaborators, and online presence, with sources and dates. Medical affairs teams use the profile to decide whether and how to engage the expert.
What is the difference between KOL profiling and KOL mapping?
Profiling builds the record for one expert. Mapping looks across many profiled experts to show how they connect and how influence flows between them, and it usually goes together with tiering, which ranks experts by influence.
What information goes into a KOL profile?
Specialty, training, and institution; publications, trial roles, grants, and presentations; guideline, society, and editorial positions; collaborators; online presence; scientific interests; and the expert's history with the company. Each item should note its source and the date it was checked.
Can prescribing data be used in KOL profiling?
Selecting HCPs for paid work based on their prescribing is a compliance risk. The OIG's 2020 Special Fraud Alert lists selection based on past or expected revenue as a suspect characteristic of speaker programs. Medical affairs profiles should rest on scientific expertise.
