Common questions
- Do Definitive Healthcare and IQVIA OneKey serve the same buyers?
- They overlap at the edges but serve different primary buyers. Definitive Healthcare targets healthcare commercial teams selling to hospitals and health systems. IQVIA OneKey targets pharmaceutical, biotech, and medtech companies managing HCP relationships. A pharma company doing hospital-system targeting might use both.
- Which platform is better for U.S. provider data?
- Both claim comprehensive U.S. provider coverage, but neither publicly documents their field-level sourcing methodology. For a primary-source, independently citable U.S. provider record, CMS NPPES is the federal baseline — 8M+ NPIs, weekly refresh, public domain, with a free REST API.
- Is IQVIA OneKey or Definitive Healthcare less expensive?
- Neither publishes pricing publicly. Both are enterprise contracts negotiated per account. Third-party procurement references for Definitive Healthcare commonly cite five- to six-figure annual ranges; IQVIA OneKey is similarly enterprise-priced but undisclosed.
- Can either platform replace federal primary sources?
- Neither is a replacement for federal primary sources. NPPES, PECOS, OIG LEIE, and CMS Care Compare are the authoritative records for NPI identity, Medicare enrollment, exclusion status, and facility quality — all publicly available, reproducible, and openly licensed. Enterprise platforms like these two layer commercial intelligence on top of federal foundations.
