What these words mean3
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.

  • Ic - Wear Gloves/Hand Hygiene

    The inspectors’ words, 728 words

    “IC-WEAR GLOVES/HAND HYGIENE CFR(s): 494.30(a)(1) Wear disposable gloves when caring for the patient or touching the patient’s equipment at the dialysis station. Staff must remove gloves and wash hands between each patient or station. This Standard is not met as evidenced by: 29963 Based on record review, observation and interview the facility staff failed to perform glove changes and/or hand hygiene when moving from “dirty” to “clean” tasks while providing cares for 3 of 10 patients (Patients #7, 10, 11); failed to ensure patients completed hand hygiene after glove removal and holding dialysis access sites until bleeding stopped for 2 of 2 patients (Patient #7, 11) observed holding access sites; and failed to wear gloves when touching the dialysis machine for 3 of 10 patients (Patients #6, 8, 10) in a total of 17 observations of patient care. Findings include: A review of the facility’s policy 1-05-01 titled, “Infection Control for Dialysis Facilities,” last revised April 2023 revealed, “All teammates ... will perform hand hygiene ... b. prior to gloving and immediately after removal of gloves, ... after patient and dialysis delivery system contact ... before touching clean areas such as supplies, supply cart, and chairside keyboard/mouse ...7. Disposable gloves will be worn when caring for the patient or touching the patient’s equipment at the dialysis station... a. Gloves should be changed when: ii. When going from a ‘dirty’ area or task to a ‘clean’ area or task... iv. After touching one patient or their dialysis delivery system and before arriving to care for another patient or touch another patient’s dialysis delivery system.” A review of the facility’s policy #1-04-01B titled, “Post Dialysis Vascular Access Care: Fistula/Graft Using Safety Fistula Needles” last revised April 2023 revealed, “... When the patient holds their cannulation sites, the patient will be offered gloves and performs hand hygiene when completed...” Examples of staff failing to complete hand hygiene: During an observation on 01/20/2026 at 10:00 AM, Patient Care Technician (PCT) C touched Patient #12’s dialysis machine then walked over to Patient #11’s dialysis machine with the same gloves and touched Patient #11’s dialysis machine without changing gloves or completing hand hygiene. During an observation on 01/20/2026 at 11:10 AM, Patient Care Technician (PCT) C was initiating dialysis on Patient #1’s Central Venous Catheter (CVC). PCT C administered heparin to Patient #1’s CVC. PCT C with same gloves walked over to Patient #7’s dialysis machine and touched the machine screen to silence an alarm. PCT C then removed gloves and put on new gloves without completing hand hygiene. During an observation on 01/20/2026 at 1:45 PM, PCT C was observed touching Patient #9’s dialysis machine and then touched Patient #10’s dialysis machine without changing gloves or completing hand hygiene. Examples of staff failing to ensure patients completed hand hygiene after glove removal after holding dialysis access sites: During an observation on 01/20/2026 at 1:35 PM, Patient #11 was observed holding dialysis access site with a gloved hand. Patient #11 removed the glove and used the scale prior to leaving the facility. Patient #11 did not perform hand hygiene prior to exiting the treatment area. During an observation on 01/20/2026 at 2:05 PM, Patient #7 was observed holding dialysis access site with a gloved hand. Patient #7 removed the glove and used the scale prior to leaving the facility. Patient #7 did not perform hand hygiene prior to exiting the treatment area. Examples of staff touching the dialysis machines with a bare hand or a glove wrapped around the finger: During an observation on 01/20/2026 at 10:35 AM, PCT D was observed to touch Patient #6’s dialysis machine without gloves. During an observation on 01/20/2026 at 10:01 AM, Biomed F touched Patient #10’s dialysis machine with her finger without putting on a glove. During an observation on 01/20/2026 at 10:20 AM, PCT C touched Patient #8’s dialysis machine with her finger without putting on a glove. During an interview on 01/21/2026 at 12:00 PM, the observation findings were discussed with Manager of Clinical Services A who stated the expectation is that staff perform hand hygiene with glove removal and that staff should be offering hand gel to every patient at the completion of dialysis. Manager of Clinical Services A stated gloves should be fully worn on the hand when touching the dialysis machine and staff should not be touching the dialysis machine without gloves.”
