IQVIA OneKey, Veeva OpenData and H1: HCP Data Options for Life Sciences (2026)
VP of Marketing, MedicalProspects
November 4, 2026
TLDR
IQVIA OneKey and Veeva OpenData are HCP and HCO reference data: the master records life sciences companies run their CRM, territories and compliance on. H1 focuses on expert and investigator discovery. None of these is mainly a campaign email list, so many teams add a contact data provider for non-personal promotion, matched to their reference data on NPI.
1. Three kinds of HCP data
| Kind | What it's for | Examples |
|---|---|---|
| Reference (master) data | CRM records, territories, compliance reporting | IQVIA OneKey, Veeva OpenData |
| Expert data | KOLs, investigators, scientific engagement | H1 |
| Campaign contact data | Verified emails and phones for outreach | MedicalProspects |
2. IQVIA OneKey vs Veeva OpenData
Both give life sciences companies HCP reference data: stable IDs for professionals and organizations, affiliations, and processes for keeping records current. The practical differences buyers weigh are:
- CRM fit: OpenData is built to work closely with Veeva CRM; OneKey is widely used across CRM platforms.
- Coverage: compare counts and attributes for your countries and specialties.
- Data stewardship: how field teams request changes and how fast they're applied.
- Commercial terms: licensing scope and how data can be used across functions.

3. Where H1 fits
H1 is used mainly by medical affairs and clinical development teams to find and profile experts: key opinion leaders, clinical trial investigators and specialists active in research. It complements reference data rather than replacing it.
4. Reference data vs campaign contacts
- Reference data keeps CRM accurate for field teams and compliance.
- Campaign contacts add verified business emails and phones for non-personal promotion, webinars and digital campaigns.
- Join them on NPI, and apply CRM opt-outs and PDRP rules across both.
5. How MedicalProspects fits
MedicalProspects covers healthcare only. MedicalProspects has 15.17M+ unique, deduplicated healthcare contacts (October 2026 refresh) across 474 specialty, executive, technology and facility lists. Because one professional can appear on several lists, list sizes overlap and are never added together. U.S. clinicians are matched to an active NPI and their taxonomy code, lists are refreshed monthly, emails are verified before each delivery with a 99% deliverability guarantee, and you can test 20 free sample records matched to your filters before you buy. Lists are sold individually or as custom builds, and we can enrich records you already hold.
Final Thoughts
Pick reference data for your CRM based on CRM fit, coverage and stewardship; add expert data if medical affairs needs it; and use a verified contact provider for campaigns. To test campaign coverage for your therapeutic area, send us your specialties and countries for a free count and sample.

Q:
What is the difference between IQVIA OneKey and Veeva OpenData?
Both provide HCP and HCO reference data for life sciences CRM: stable IDs, affiliations and change management. OneKey is IQVIA's long-established reference data; OpenData is Veeva's, designed to work closely with Veeva CRM. Teams usually choose based on their CRM, coverage needs and data stewardship processes.
Q:
What is H1 used for?
H1 focuses on finding and profiling healthcare experts, such as key opinion leaders and clinical trial investigators, for medical affairs and clinical development teams.
Q:
Do I need reference data and a contact list?
Often, yes. Reference data is the system of record in CRM; campaign contact lists provide verified emails and phones for non-personal promotion and marketing. Match the two on NPI and apply CRM opt-outs to every campaign list.
Q:
Can MedicalProspects replace IQVIA OneKey?
No. MedicalProspects provides campaign-ready contact data, not CRM reference data. Many life sciences teams use it alongside their reference data provider for email and digital campaigns.
