F 0578 Level of Harm - Minimal harm or potential for actual harm Residents Affected - Some Honor the resident's right to request, refuse, and/or discontinue treatment, to participate in or refuse to participate in experimental research, and to formulate an advance directive. **NOTE- TERMS IN BRACKETS HAVE BEEN EDITED TO PROTECT CONFIDENTIALITY** Based on interview and record review, the facility failed to ensure three of three sampled residents (Residents 7, 27, and 83) and/or their Responsible Parities (RP) were offered and provided information regarding the right to formulate an advance directive (AD, legal documents that provide instructions for medical care and only goes into effect if the resident cannot communicate their wishes). This deficient practice had the potential to result in lack of knowledge regarding care and treatment decision making and the potential for Residents 7, 27 and 83 to receive unwanted care/treatment or unnecessary life-sustaining treatment. Findings: A. During a record review of Resident 7's admission Record (AR), the AR indicated the resident was admitted to the facility on [DATE] with diagnosis that included kidney failure (condition where the kidneys are unable to properly filter waste products), depression, and hypertension (elevated blood pressure). During a record review of Resident 7's Minimum Data Set (MDS, a resident assessment and care-screening tool), dated 1/20/2025, the MDS indicated Resident 7 was cognitively intact. The MDS indicated Resident 7 needed maximal assistance (helper does more than half the effort) with oral and toilet hygiene, upper and lower body dressing, and sit to stand (ability to stand from sitting on a chair). During an interview and concurrent record review of Resident 7's medical record, with the Social Services Director (SSD), on 2/7/2025 at 8:50 PM, the SSD stated Resident 7 did not have an AD. The SSD stated Resident 7 should have been asked and offered an AD to educate the resident of their health care choices and document the wishes of Resident 7 regarding life sustaining options. B. During a record review of Resident 27's MDS, dated [DATE], the MDS indicated Resident 27 was cognitively intact. The MDS indicated Resident 7 needed maximal assistance with oral and toilet hygiene, upper and lower body dressing, and sit to stand. During a review of Resident 27's AR indicated Resident 27 was admitted to the facility on [DATE] with diagnosis that included artificial right hip joint, dysphagia (difficulty swallowing), and anxiety (a feeling of worry, nervousness, or unease). During a review and concurrent record review of Resident 27's medical record, on 2/7/2025 at 8:32 PM, Registered Nurse 1 (RN 1) stated RN 1 was not sure if Resident 27 had an AD. RN 1 stated RN 1 was not sure if the facility offered Resident 27 information about an AD. RN 1 stated the SSD was the person responsible and discusses ADs with residents/RPs upon admission. C. During a review of Resident 83's AR, the AR indicated the resident was admitted to the facility on [DATE] with diagnosis that included dementia (a decline in mental ability severe enough to interfere with daily life) and psychosis (a mental health problem that causes people to perceive or interpret things differently from those around them).

Level of Harm - Minimal harm or potential for actual harm During an interview and concurrent record review of Resident 83's medical record, with the SSD, on 2/7/2025 at 8:52 pm, the SSD stated Resident 83 did not have an AD. The SSD stated there was no documented evidence indicating an AD was offered to Resident 83's RP. The SSD stated this was important to know Resident 83's or the resident's RP wishes and for proof that the AD was offered, and that the resident was educated about AD. Residents Affected - Some During a record review of the facility's policy and procedure (P&P), revised on 9/2022, the P&P indicated the resident has the right to formulate an advance directive, including the right to accept or refuse medical or surgical treatment. Advanced directives are honored in accordance with state law and facility policy.

F 0580 Level of Harm - Minimal harm or potential for actual harm Residents Affected - Few Immediately tell the resident, the resident's doctor, and a family member of situations (injury/decline/room, etc.) that affect the resident. Based on interview and record review, the facility failed to notify the physician regarding pharmacy delays and inability to carry out the physician's order for Vagisil (a medication used to relieve vaginal itching, irritation, and burning) for one of one sampled resident (Resident 11). This deficient practice resulted in delayed provision of necessary care and services for Resident 11. Findings: During a review of Resident 11's admission Record (AR), the AR indicated the facility admitted Resident 11 on 1/18/2025, with diagnoses including malignant neoplasm of corpus uteri (endometrial cancer, a cancer of the lining of the uterus [a pear-shaped organ in the reproductive system of females]), type 2 diabetes mellitus (DM, a disorder characterized by difficulty in blood sugar control and poor wound healing), and history of falling. During a review of Resident 11's Minimum Data Set (MDS, a federally mandated resident assessment tool), dated 1/25/2025, the MDS indicated Resident 11 had moderate cognitive (the ability to think and process information) impairment. The MDS indicated Resident 11 required substantial/maximal assistance (helper does more than half the effort) with activities of daily living (ADL, term used in healthcare that refers to self-care activities) and partial/moderate assistance (helper does less than half the effort) with mobility. During a record review of Resident 11's Order Summary Report (OSR), active orders as of 2/1/2025, indicated Resident 11 had an active order for: -Vagisil External Cream 1% (Hydrocortisone Acetate Vaginal), apply to vaginal area topically (medication application on the surface of the body such as the skin) one time a day for vaginal itching. The order date for the Vagisil was made on 2/1/2025 with a treatment start date of 2/2/2025. During an interview on 2/7/2025 at 6:31 PM, with Resident 11, Resident 11 stated she was frustrated and upset because she had very uncomfortable vaginal itching and a vaginal burning sensation for about one week. Resident 11 stated she notified the facility staff about her symptoms, however, the facility staff kept telling her that they were still waiting for the medication from the pharmacy. Resident 11 stated she hadn't received any treatment for the awful discomfort she had been experiencing from the vaginal itching and burning. During an interview and record review on 2/8/2025 at 3:07 PM, with Registered Nurse (RN) 1, Resident 11's OSR was reviewed, RN 1 stated Resident 11 had a Vagisil order that should have been started on 2/2/2025. RN 1 stated the facility had not received the medication from the pharmacy delaying Resident 11's treatment. RN 1 stated nursing staff should have contacted the physician to make them aware of the pharmacy delay for Vagisil. RN 1 stated treatment delays could worsen Resident 11's condition, cause increased discomfort, or lead to complications. During an interview on 2/9/2025 at 8:30 AM, with the Director of Nursing (DON), the DON stated licensed nurses should be notifying the physician of any pharmacy delays regarding prescribed medication orders.

F 0584 Level of Harm - Minimal harm or potential for actual harm Residents Affected - Few Honor the resident's right to a safe, clean, comfortable and homelike environment, including but not limited to receiving treatment and supports for daily living safely. Based on observation, interview, and record review, the facility failed to ensure one of two sampled residents (Resident 27) was provided a safe and homelike environment when Resident 27's toilet leaked and caused water to puddle on the bathroom floor. This failure had the potential for Resident 27 to be injured from a fall and had the potential for Resident 27 to not be comfortable in his environment. Findings: During a review of Resident 27's admission Record (AR), the AR indicated the facility admitted Resident 27 on 12/17/2024, with diagnoses including type 2 diabetes mellitus (a chronic condition that affects the way the body processes blood sugar), aftercare following joint replacement surgery, and anxiety disorder (mental health disorder characterized by feelings of worry, anxiety, or fear that are strong enough to interfere with one's daily activities). During a review of Resident 27's Minimum Data Set (MDS, a resident assessment tool), dated 12/21/2024, the MDS indicated Resident 27 had no impairment in cognitive skills (ability to make daily decisions). The MDS indicated Resident 27 required substantial/maximal assistance (helper does more than half the effort) from staff for oral, toileting, and personal hygiene and dressing. During a concurrent observation and interview on 2/7/2025 at 7:01 PM with Resident 27, in Resident 27's bathroom, a puddle of water was observed on the floor, on the right side of Resident 27's bathroom toilet, between the toilet and the wall. A white towel was on the floor in front of the toilet. Resident 27 stated Resident 27 used the toilet. Resident 27 stated the toilet started leaking on 2/6/2025 after three men (unidentified) were working on the toilet plumbing. Resident 27 stated Resident 27 informed some of the nurses (unidentified) of the leaking toilet. During a concurrent observation and interview on 2/8/2025 at 9:55 AM with the Plant Operations Director (POD), a puddle of water was observed in front of, and to the right of Resident 27's bathroom toilet. The POD confirmed the puddle of water was from the leaking toilet. The POD confirmed the toilet had been leaking for three days. The POD stated the puddle of water was a safety risk to Resident 27. During a review of the facility's policy and procedure (P&P) titled, Homelike Environment, revised February 2021, the P&P indicated, Residents are provided with a safe, clean, comfortable and homelike environment . The P&P indicated, .The facility staff and management maximizes, to the extent possible, the characteristics of the facility that reflect a personalized, homelike setting.

This deficient practice had the potential for CNA 5 not being able to provide emergency basic life support, including cardiopulmonary resuscitation (CPR), to any resident requiring such care during an emergency and prior to the arrival of emergency medical personnel. Cross Reference F726 Findings: During an interview and concurrent record review with the Director of Staff Development (DSD) of CNA 5's personnel record (employee personal information), on [DATE] at 10:48 AM, the DSD stated the DSD was not able to provide a copy of CNA 5's current BLS/CPR card/certification because CNA 5's card was expired. The DSD stated the facility was not able to provide a current BLS/CPR card nor provide any documentation to indicate CNA 5 took the necessary courses to obtain a BLS/CPR card. During an interview with the Director of Nursing (DON), on [DATE] at 11:36 AM, the DON stated Staff was defined as people that worked here (at the facility). The DON stated CPR was done for residents who became non-responsive. The DON stated, I would have all my staff perform CPR. The DON stated all staff should call for a code blue (emergency code that indicates a patient needs immediate medical attention, usually due to cardiac or respiratory arrest), then start compressions: 30 compressions to 2 breaths ratio. The DON stated it was not OK not to do anything and stand by to wait for assistance because you are talking about a life. The DON stated [staff had to] do what is necessary to save a life. During an interview and concurrent record review with the DSD, on [DATE] at 12:55 PM, the facility's document titled, CNA Tracking, was reviewed, the tracking indicated the column titled CPR Issued Date and CPR Exp. [expiration] Date was left blank. The DSD stated the CNA tracking log was incomplete. The DSD stated it was important to ensure completion of tracking to see if CNA BLS/CPR cards were expired and know when it was time for renewal. The DSD stated the DSD would like all staff to know how to perform CPR because CPR was lifesaving, and every second counted. During an interview with the DSD on [DATE] at 12:55 PM, the DSD stated the facility did not have a policy specifically for CPR. During an interview with the Administrator (ADM), on [DATE] at 1:01 PM, the ADM stated the facility's practice was to obtain information from the State Operations Manual (SOM, is a federal document, issued by CMS, containing survey and certification rules and guidance) to develop policies and procedures (P&P).

This deficient practice had the potential to affect the care provided to residents, quality of life, and the potential for the residents not to receive nursing services in a timely matter. Findings: A. During a review of Resident 19's admission Record (AR), the AR indicted Resident 19 was admitted to the facility on [DATE] with diagnosis that included hemiplegia and hemiparesis (muscle weakness on one side of the body) of the right dominant side, muscle wasting, and difficulty walking. During a review of Resident 19's History and Physical (H&P), dated 1/12/2025, the H&P indicated Resident 19 had the capacity to understand and make decisions. During a review of Resident 19's Minimum Data Set (MDS, a resident assessment and care-screening tool), dated 1/17/2025, indicated Resident 19 was moderately impaired cognition and needed partial/moderate assistance (helper does less than half the effort) with showers and lower body dressing. During a review of Resident 19's care plan (CP), titled ADL (Activities of Daily Living, basic self-care task performed daily), initiated 1/10/2025, the CP's focus indicated Resident 19 required assistance from 1-2 persons to start and complete most ADL task - toileting, transfers, hygiene/grooming, bathing and eating. During an interview with Resident 19 on 2/8/2025 at 9 AM, Resident 19 stated at night (unknown days), Resident asked for assistance and needed to wait up to 30 minutes for a staff member to respond.

F 0732 Post nurse staffing information every day. Level of Harm - Minimal harm or potential for actual harm Based on interview and record review, the facility failed to post accurate nurse staffing information of actual hours worked by the licensed and unlicensed nursing staff who were directly responsible for resident care per shift, daily. This information was not posted in a prominent location readily accessible to residents and visitors for viewing. Residents Affected - Few This failure resulted in no posting of nurse staffing hours and had the potential to result in lack of nurse staffing hour knowledge for residents and family members. Findings: During an interview and concurrent record review with the Director of Staff Development (DSD), on 2/9/2025 at 10:48 AM, the facility's Daily Staffing and Posting and Census dated 2/7/2025 and 2/8/2025 were reviewed. The DSD stated actual hours worked by the nursing staff for those dates were not recorded/posted. The DSD stated actual hours were calculated by the next business day and on weekends, actual hours worked were calculated by the following Monday. The DSD stated it was important to post actual working hours worked to ensure the correct number of worked hours and ensure staff were accounted for, and for resident awareness. During a review of the facility's policy and procedure (P&P) titled, Posting Direct Care Daily Staffing Numbers, revised August 2022, the P&P indicated the facility will post on a daily basis for each shift nurse staffing data, including the number of nursing personal responsible for providing direct care to the resident. The actual time worked during that shift for each category and the type of nursing staff; and the total number of licensed and non-licensed nursing staff working for that posted shift.

F 0756 Level of Harm - Minimal harm or potential for actual harm Residents Affected - Few Ensure a licensed pharmacist perform a monthly drug regimen review, including the medical chart, following irregularity reporting guidelines in developed policies and procedures. Based on interview and record review, the facility failed to follow through with the Consultant Pharmacists recommendations during the Medication Regiment Review (MRR, a review of all medications the resident is currently using to minimize adverse consequences and potential risks associated with medications) for one of five sampled residents (Resident 21). This failure had the potential for Resident 21 to not receive the necessary blood tests for Resident 21's health and wellbeing. Findings: During a review of Resident 21's admission Record (AR), the AR indicated the facility admitted Resident 21 on 1/8/2025, with diagnoses including cerebral infarction (also called ischemic stroke, occurs as a result of disrupted blood flow to the brain), urinary tract infection (UTI, an infection in any part of the urinary system, including the kidneys, bladder, or urethra),and type 2 diabetes mellitus (a chronic condition that affects the way the body processes blood sugar). During a review of Resident 21's Minimum Data Set (MDS, a resident assessment tool), dated 1/15/2025, the MDS indicated Resident 21 was moderately impaired in cognitive skills (ability to make daily decisions). The MDS indicated Resident 21 was dependent (helper does all the effort) on staff for toileting, oral, and personal hygiene, dressing, and showering/bathing. During a concurrent interview and record review on 2/8/2025 at 3:14 PM with Registered Nurse (RN) 1, Resident 21's two Consultation Reports, from the facility's Consultant Pharmacist both dated 1/15/2025 were reviewed. The first Consultation Report indicated the pharmacist recommended a thyroid-stimulating hormone (TSH- triggers the thyroid [a gland at the front of the neck that control the way the body uses energy] to release its hormone) blood test (measures the amount of TSH in the bloodstream) to be drawn for Resident 21. The second Consultation Report indicated the pharmacist recommended an A1C (a blood test that measures the average blood sugar [glucose] level over the past 2-3 months) to be drawn for Resident 21. Both Consultation Reports indicated Resident 21's physician accepted the recommendations to draw the laboratory tests for Resident 21. RN 1 stated the Consultant Pharmacist (Pharm 1) created the Consultation Reports during the monthly MRR. RN 1 stated the facility drew blood tests for Resident 21 on 1/16/2025 and 1/23/2025 but did not include the blood tests for A1C and TSH as recommended by Pharm 1 and approved by Resident 21's physician. RN 1 stated the facility did not follow through with Pharm 1's MRR recommendations. During a review of the facility's policy and procedure (P&P) titled, Medication Regimen Review, dated 12/1/2007, the P&P indicated, The Consultant Pharmacist will conduct MRRs if required under a Pharmacy Consultant Agreement. The P&P indicated, Facility should encourage Physician/Prescriber or other Responsible Parties receiving the MRR and the Director of Nursing to act upon the recommendations contained in the MRR. For those issues that require Physician/ Prescriber intervention, Facility should encourage Physician/Prescriber to either (a) accept and act upon the recommendations contained within the MAR, or (b) reject all or some of the recommendations contained in the MAR and provide an explanation as to why the recommendation was rejected.

F 0842 Level of Harm - Minimal harm or potential for actual harm Residents Affected - Few Safeguard resident-identifiable information and/or maintain medical records on each resident that are in accordance with accepted professional standards. Based on interview and record review, the facility failed to ensure accurate medication administration documentation for one of one sampled resident (Resident 11) when, the facility inaccurately documented the administration of Resident 11's Vagisil (a medication used to relieve vaginal itching, irritation, and burning) on 2/4/2025. This deficient practice had the potential to lead to inconsistent and/or inaccurate treatments provided to Resident 11. Findings: During a review of Resident 11's admission Record (AR), the AR indicated the facility admitted Resident 11 on 1/18/2025, with diagnoses including malignant neoplasm of corpus uteri (endometrial cancer, a cancer of the lining of the uterus [a pear-shaped organ in the reproductive system of females]), type 2 diabetes mellitus (DM, a disorder characterized by difficulty in blood sugar control and poor wound healing), and history of falling. During a review of Resident 11's Minimum Data Set (MDS, a federally mandated resident assessment tool), dated 1/25/2025, the MDS indicated Resident 11 had moderate cognitive (the ability to think and process information) impairment. The MDS indicated Resident 11 required substantial/maximal assistance (helper does more than half the effort) with activities of daily living (ADL, term used in healthcare that refers to self-care activities) and partial/moderate assistance (helper does less than half the effort) with mobility. During a record review of Resident 11's Order Summary Report (OSR), active orders as of 2/1/2025, indicated Resident 11 had an active order for: -Vagisil External Cream 1% (Hydrocortisone Acetate Vaginal), apply to vaginal area topically (medication application on the surface of the body such as the skin) one time a day for vaginal itching.

Level of Harm - Minimal harm or potential for actual harm RN 1 stated LVN 2 inaccurately documented the administration of Resident 11's Vagisil on 2/4/2025. RN 1 stated the facility had not received the medication from the pharmacy and Resident 11 had not started the treatment. RN 1 stated LVN 2 acted in good faith and did not intend to falsify the record, seeing that LVN 2 documented the Vagisil was not available for administration on 2/5/2025. RN 1 stated accurate MAR documentation helped with tracking the effectiveness of medications, identify side effects (unwanted, uncomfortable, or dangerous effects that a resident may have due to a medication), and ensured timely adjustments were made to the resident's treatment plan. Residents Affected - Few During an interview on 2/9/2025 at 8:30 AM, with the Director of Nursing (DON), the DON stated staff should ensure accurate MAR documentation. The DON stated accurate documentation allowed for clear communication between healthcare providers, and helped ensure the next caregiver or healthcare provider had a complete and accurate record of a resident's medication regimen, improving the quality of care. The DON stated proper documentation ensured there was no confusion or misunderstanding among staff members regarding medication administration, reduced the risks of errors due to miscommunication.

F 0880 Provide and implement an infection prevention and control program. Level of Harm - Minimal harm or potential for actual harm Based on observation, interview, and record review, the facility failed to maintain infection prevention and control practices for one of one sampled resident (Resident 11) by failing to ensure Resident 11's wound vacuum (a suction device that is applied after a wound is dressed) drainage tubing did not have direct contact with the floor. Residents Affected - Few This deficient practice had the potential to result in the transmission of infectious microorganisms and increase the risk of infection for Resident 11. Findings: During a review of Resident 11's admission Record (AR), the AR indicated the facility admitted Resident 11 on 1/18/2025, with diagnoses including malignant neoplasm of corpus uteri (endometrial cancer, a cancer of the lining of the uterus [a pear-shaped organ in the reproductive system of females]), type 2 diabetes mellitus (DM, a disorder characterized by difficulty in blood sugar control and poor wound healing), and history of falling. During a review of Resident 11's Minimum Data Set (MDS, a federally mandated resident assessment tool), dated 1/25/2025, the MDS indicated Resident 11 had moderate cognitive (the ability to think and process information) impairment. The MDS indicated Resident 11 required substantial/maximal assistance (helper does more than half the effort) with activities of daily living (ADL, term used in healthcare that refers to self-care activities) and partial/moderate assistance (helper does less than half the effort) with mobility. During an observation on 2/7/2025 at 6:31 PM, Resident 11 was observed with a wound vacuum that was attached to Resident 11's abdomen. The wound vacuum pump was resting on Resident 11's bed and the wound vacuum drainage tubing was touching the floor. During an interview on 2/7/2025 at 6:48 PM, with Certified Nursing Assistant (CNA) 4, CNA 4 stated Resident 11's wound vacuum tubing should not be touching the floor because [contact with the floor] could lead to cross contamination (process by which bacteria can be transferred from one area to another). CNA 4 stated if the tubing carried bacteria from the floor to the wound it could lead to an infection. During an interview on 2/9/2025 at 8:12 AM, with Infection Preventionist (IP) 1, IP 1 stated keeping the wound vacuum tubing off the floor reduced the risk of contamination and ensured a wound healing process not disrupted by external pathogens (organism that causes disease to its host). IP 1 stated any part of the system that touched the floor could potentially break the sterile field, putting the wound at greater risk of becoming infected. During a review of the facility's Policy and Procedure (P&P) titled, Infection Prevention and Control Program revision dated 10/2018, the P&P indicated an infection prevention and control program (IPCP) is established and maintained to provide a safe, sanitary, and comfortable environment and to help prevent the development and transmission of communicable diseases and infections.
