Not listed: 7 campuses Illinois licenses on their own of hospitals CMS lists, 2 long-term acute care hospitals’ second sites, each under the one CMS number its other site holds and 1 hospital of a health system that CMS’s files may hold under another of the system’s hospitals, so not called uncertified.

What the words on these cards mean7
Star ratings
CMS rates some kinds of place from 1 to 5 stars, more stars meaning better on CMS’s own measures for that kind: for a nursing home, its health inspections, staffing and quality measures. A rating is CMS’s summary of those measures; it doesn’t promise good care. Source: CMS, Care Compare and the Five-Star Quality Rating System.
Inspection (survey)
A visit by state inspectors, often unannounced, who check a place against the rules it must meet. For nursing homes and other places Medicare pays, CMS calls these visits surveys: a standard survey of a nursing home comes at least every 15 months, and a complaint survey whenever a complaint calls for one. Source: CMS; 42 CFR 488.308.
Deficiency, citation, violation
What inspectors write up when a place didn’t meet a rule: the rule, what they saw, and when. CMS calls it a deficiency; states may say citation or violation. It is the inspectors’ finding, not a court’s, and the place is usually asked for a plan to correct it. Source: CMS, statement of deficiencies (Form CMS-2567); each state’s licensing agency.
Condition-level deficiency
For hospices, home health agencies, hospitals and dialysis facilities, CMS writes deficiencies at two levels. Standard is the usual one; condition-level is the more serious, when a problem is serious enough that the provider doesn’t meet a whole condition of taking part in Medicare. Source: CMS, State Operations Manual.
Immediate jeopardy
CMS’s most serious finding: the place’s failure to meet a rule caused, or was likely to cause, serious injury, harm, impairment or death to someone in its care. Source: CMS; 42 CFR 489.3.
None on record
The source lists nothing of this kind for the place, over the years its file covers. That is what the record holds, not proof that nothing ever happened. Source: How this site reads each source.
Not published
The source has no such field for this place. It isn’t a zero, and it isn’t a clean record. Source: How this site reads each source.

    Side by side

    The same published facts for each, in the same order, in their sources’ words.

    Every line is a fact its source published, in that source’s own words. On a line whose figures can be ordered, the one that leads is marked; that is not a rating, and no line is weighed against another. “Not published” means that state’s file has no such field, which is not the same as a zero.
