Dyania Health vs HealthKey (2026)

AI Health Index verifiedOctober 15, 2026
Verdict

Dyania Health and HealthKey search patient records for potential clinical trial participants, with people confirming eligibility. Dyania combines an internal health system deployment with physician review services; HealthKey emphasizes protocol configured screening for research practices and networks. Dyania's Synapsis AI answers defined clinical questions from structured and unstructured records rather than generating general summaries. Patient Finder runs inside the health system's firewall, and Dyania physicians review results before delivery. Cleveland Clinic also confirmed matches before patient contact and expanded its deployment after work in cancer and cardiovascular disease. Reported screening results concern particular studies, and what happens to eligible patients the system never surfaces is not described. HealthKey applies inclusion and exclusion criteria to EHR fields, notes and faxed documents. Coordinators use evidence linked candidate lists, with near matches separated for judgment. Oregon Urology, Flourish Research and Tekton Research provide examples across different conditions and EHRs. Its case studies distinguish screening and enrollment stages but do not measure all missed eligible patients. Dyania fits health systems wanting chart screening within their own environment with an added physician review layer. HealthKey fits research sites connecting community clinic records to study specific candidate workflows. Both reduce initial chart search work while leaving qualification and patient approach with the research team.

The case for Dyania Health
  • Patient records should remain inside the health system firewall.
  • Physician review is wanted before results reach the customer.
  • Screening should answer defined clinical questions across full records.
  • A health system plans an enterprise chart review deployment.
The case for HealthKey
  • Research spans community clinics and several study protocols.
  • Coordinators need evidence linked candidate and near match lists.
  • The workflow should support dashboard access and candidate updates.
  • Protocol specific screening must work across connected practice EHRs.

FAQ

Questions buyers ask

How are Dyania Health and HealthKey priced and sold?

For Dyania Health, the company says health systems with about 500,000 patients spend more than $5 million a year on staff doing manual chart abstraction, and describes a one-time deployment inside the health system followed by the company's ongoing maintenance and physician review.

With HealthKey, implementation involves connecting the clinic's records and configuring the protocol's inclusion and exclusion logic, with support for research teams reviewing the results. The homepage's $0 upfront offer expired July 31, 2026, so its assigned values for implementation, setup of five trials, and support no longer describe current charges.
