A citation is what inspectors found on one date; most are corrected within weeks. Look for patterns — the same problem cited in several inspections — and for anything at the G–L level (actual harm or immediate jeopardy). The full inspection narrative (Form CMS-2567) is linked from Medicare Care Compare, and your state long-term care ombudsman can tell you about complaints.
