HCP Reach
The number or percentage of distinct healthcare professionals in a defined target universe who were exposed to or engaged by a campaign.
Definition
HCP Reach measures unique healthcare professionals reached within a reporting period. The denominator, when reported as a rate, should be an explicitly defined target HCP universe, and identification should use a documented HCP identity method such as an NPI-based or vendor-verified match.
Formula
Distinct reached HCPs / eligible target HCPs
