How to find key opinion leaders: sources and search strategy

Choose sources based on what you need to learn. No single source answers every selection question. A congress programme may show a speaking role without establishing a current affiliation, while an institutional biography may describe a role without documenting recent work in the specific topic.

Translate the brief into clinical terms, synonyms, geography and relevant activities. Start with the subject itself, then explore more specific questions. Keep aliases together so the same concept is not treated as several separate requirements.

For publication searching, use the database's own help to understand author fields, date filters and search behaviour. PubMed supports author searches and filters, but a search result still needs interpretation. If you search a common surname with initials, inspect affiliations and subject areas before assigning papers to a candidate.

Record the query and date for each meaningful search. This gives the team a way to revisit the work, explain its scope and test whether a narrow filter excluded relevant people. Remove a restriction deliberately rather than changing several variables without noting the effect.

Start with several independent routes into the field. Look at relevant research, recent programme faculty and the clinical services or groups connected to the topic. Then examine whether your longlist overrepresents one institution, geography or type of activity.

Use related authors and professional collaborations as leads for additional research, not as proof of influence. Co-authorship does not establish a personal relationship, shared opinion or willingness to participate in a project. Each newly identified person needs their own profile and source checks.

Emerging researchers and local clinicians may be valuable for specific questions even when they have fewer publications than established academic leaders. Evaluate them against the contribution the project needs. Avoid treating public visibility as a complete measure of professional expertise.

At the discovery stage, aim for a compact record that can support the next decision. Include name, likely institution, geographic relevance, the reason for investigating and the best available source links. Flag any identity ambiguity before collecting more activity under that name.

Do not overinvest in detailed biographies for every lead. Apply a light relevance screen, then spend deeper verification effort on the candidates who could meet the brief. Preserve the reason a person was excluded or deferred so another team member does not repeat the same search later.

Assess coverage against the brief, not the size of the spreadsheet. Have you explored the required countries and professional perspectives? Are the same names appearing because they dominate the field, or because all your searches use the same source?

Agree a stopping point with the project owner. A practical longlist should contain enough potentially relevant people to support the target shortlist and sensible alternatives. Document important gaps rather than adding weak candidates solely to reach an arbitrary total.
