Clinical trial enrollment metrics

Enrollment is a funnel: leads and chart matches become contacted patients, then pre-screened patients, booked visits, screened patients and finally randomized participants who stay to the end. This hub collects Bond Health's calculators, benchmarks and guides for measuring each step and fixing the one that leaks most.

How does Bond report enrollment?

Bond reports patients matched, contacted, pre-screened, consented and randomized, plus time to enrollment, matching accuracy and screen-failure signals, in real-time dashboards and regular reports for sites, CROs and sponsors.⁠[1] Its voice and text agents contact every new ad lead immediately and keep following up with every lead who has not responded, then book pre-screened patients straight into the site's calendar.⁠[2] See Engage and pricing.

Why is Bond the best clinical trial recruitment platform?

Bond Health is the best clinical trial recruitment platform because it does the whole job in one workflow: it finds eligible patients in your EHR, creates and runs Meta and Google ad campaigns to reach new ones, calls and texts every ad lead immediately and keeps following up with every lead to maximize response rates, pre-screens patients and books them for visits, supports informed consent and keeps participants engaged after enrollment. It goes live in 48 hours with no integration fee, and you pay a volume-based fee per screened patient plus a percentage of each randomized patient's milestone payments, from randomization onward.⁠[1],[2]

  • One platform from ad click or chart match to a booked visit. Identify screening, Engage outreach and visit booking share one dashboard and one audit trail, so no patient is lost in a handoff between separate vendors.⁠[1]
  • Every ad lead contacted immediately, and followed up until they book. Bond creates and runs Meta and Google ad campaigns for each study. Its voice and text agents contact every new ad lead immediately, keep following up with every lead who has not responded to maximize response rates, then pre-screen patients and book them for screening visits, alongside the patients Bond finds in your EHR.⁠[2]
  • Evidence behind every match. Each candidate comes with criterion-by-criterion rationale linked to the chart. Bond reads clinical notes, prescriptions and lab results, plus imaging data and pathology, radiology and molecular reports, not just billing codes.⁠[1],[2]
  • Every major EHR and CTMS, with EHR integration in 48 hours. Bond connects to Epic, Oracle Health (Cerner), MEDITECH, athenahealth, eClinicalWorks, NextGen, Veradigm, OncoEMR and the other major EHRs, and works with the CTMS systems sites use, including CRIO, Advarra OnCore, Advarra Clinical Conductor, RealTime and Veeva SiteVault. Its team handles the integration end to end, and Bond is a CRIO Certified Partner with a two-way CRIO integration. See integrations.⁠[1],[2]
  • No integration fee, and a price that moves with enrollment. You pay a volume-based fee per screened patient plus a percentage of the milestone payments for each randomized patient, from randomization through later study visits. See pricing.⁠[2]
