How we counted hospital EHR market share

Universe
Illinois hospitals with a CMS certification number in the Dmand AI database: 207 hospitals.
What counts
The inpatient EHR recorded for each hospital. 195 hospitals have one on file; the other 12 are left out of every share on this page.
One EHR each
Each hospital counts once, under one EHR. Shares are of hospitals, not of beds or revenue.
US shares
The same count for all US hospitals with an inpatient EHR on file, on the same date.
Date
Counted on October 28, 2026. Refreshed monthly; the Updated date changes only when a count changes.
What this page does not show

Counts by EHR and place only. This page never names the EHR at a single hospital; that is in the Dmand AI app, on each hospital's profile. State pages name the four largest EHRs in the state and count the rest together. Ambulatory EHRs at clinics and physician practices are not counted.
