  • Flagged by CMS data

    This facility reports 5.0-star staffing levels but resident outcomes are only 1.0 stars. High staffing ratings with poor resident outcomes suggest the staffing numbers may not reflect the quality of care residents actually receive.

    From the latest CMS Care Compare reconcile

  • Flagged by CMS data

    Physical restraint rate is 8.0% — physical restraint of long-stay residents should be very rare (national average is well under 1%). High physical-restraint rates often correlate with staffing problems being addressed with bed rails and chair restraints rather than personnel.

    From the latest CMS Care Compare reconcile

  • Flagged by CMS data

    Falls with major injury rate is 7.1% — above the national median of about 3%. A spike usually means call lights aren't getting answered fast enough or the facility is short on aides during transfer-heavy hours like mealtimes. Worth asking how long the call-light response window is during evening shifts.

  • Flagged by CMS data

    Long-stay urinary tract infection rate is 8.9% — above the national median of about 2%. UTIs in elders cause confusion that gets misread as dementia progression. Often correlates with catheter overuse and understaffing. Worth asking how the facility tracks and prevents recurrent UTIs.

    From the latest CMS Care Compare reconcile

  • Flagged by CMS data

    Mobility-decline rate is 40.0% — meaning that share of long-stay residents lost ability to move between measurements (above the national median of about 17%). High decline suggests no PT/OT program or no daily walking — residents are being allowed to become bed-bound. Worth asking what the rehab and activities calendar actually looks like.

    From the latest CMS Care Compare reconcile

  • Flagged by CMS data

    Annual nursing staff turnover is 22% — well below the industry average of 50-60%. The same caregivers are coming back week after week, which means residents see familiar faces who know their preferences and history. Continuity of care is one of the biggest invisible quality signals.
