F 0637 Level of Harm - Minimal harm or potential for actual harm Resident 35 had declined in multiple areas of health status. The DON stated these declines began shortly after she contracted COVID-19 in November of 2022. Further review of Resident 35's medical record indicated the facility did not complete a significant change in status MDS to address the above declines in the resident's health status. Residents Affected - Few During an interview with the Minimum Data Set Coordinator (MDSC) on 2/24/23 at 10:44 a.m., she reviewed Resident 35's medical record and confirmed the facility did not complete a significant change in status MDS. The MDSC confirmed Resident 35 declined in multiple areas of health status and acknowledged a significant change in status MDS should have been completed. Review of the Centers for Medicare & Medicaid Services 2019 Long-Term Care Facility Resident Assessment Instrument 3.0 User's Manual (RAI manual, MDS instructions) indicated, The SCSA [significant change in status assessment] is a comprehensive assessment for a resident that must be completed when the IDT has determined that a resident meets the significant change guidelines for either major improvement or decline. The RAI manual indicated a significant change is a major decline in a resident's status that would not normally resolve without intervention, impacts more than one area of the resident's health status, and requires interdisciplinary review and/or revision of the care plan.

F 0684 Provide appropriate treatment and care according to orders, resident’s preferences and goals. Level of Harm - Minimal harm or potential for actual harm **NOTE- TERMS IN BRACKETS HAVE BEEN EDITED TO PROTECT CONFIDENTIALITY** Based on observation, interview, and record review, the facility failed to ensure one of four residents (Resident 60) had hearing aids on while awake for optimal hearing abilities. This failure had the potential to result in ineffective and insufficient communication between Resident 60 and caregivers, and could have negatively affected the resident's psychosocial well-being. Residents Affected - Few Findings: During a concurrent observation and interview, on 2/21/23, at 11:45 a.m., in Resident 60's room, Resident 60 was observed lying in the bed awake without his hearing aids on. The hearing aids were on the nightstand behind his bed. The surveyor asked Resident 60 the same question three times and the resident was not able to answer. He pointed to his ears, stated he could not hear and that he needed the hearing aids. During an interview on 2/21/23, at 12:00 p.m., with registered nurse A (RN A), he stated usually Resident 60's wife came before lunch time, and she put the hearing aids on. During an observation on 2/22/23, at 11:40 a.m., in Resident 60's room, Resident 60 was observed again lying in his bed awake without the hearing aids on. A review of Resident 60's Face Sheet (a document that gives a resident's information at a quick glance, including contact details and a brief medical history) indicated the resident was admitted to the facility on [DATE], with the diagnoses of osteomyelitis (an infection of the bone) of lumbar spine and need for assistance with personal care. A review of Resident 60's Minimum Data Set (MDS, a resident clinical assessment), dated 1/16/23, indicated the resident's Brief Interview for Mental Status (BIMS, a brief cognitive screening tool) score was 13, which indicated Resident 60 was cognitively intact. It also indicated Resident 60 had moderate hearing difficulty and required extensive assistance (weight-bearing support) with activities of daily living (ADLs), except eating. A review of Resident 60's care plan (CP, provides direction on the type of nursing care the resident may need), initiated on 1/11/23, indicated, Ensure hearing aid(s) (left and right) is in place and functioning. During a concurrent interview and record review on 2/22/23, at 12:11 p.m., with the social services manager (SSM), the SSM reviewed Resident 60's physician orders and confirmed there was no order for Resident 60's hearing aids applying and removal schedule. The SSM further stated there should have been an order. During an interview on 2/22/23, at 12:38 p.m., with the director of staff development (DSD), he stated residents with hearing aid should always have a schedule order that indicated when to put on and when to remove the hearing aids. During an interview on 2/22/23, at 12:45 p.m., with the director of nursing (DON), she stated the licensed nurse was responsible to put on and remove the hearing aids. The DON stated the staff who received the hearing aids should have put in an applying/removal schedule order.

His wife stated she did not usually put the hearing aids on, she was hoping the facility staff could put them on every morning after breakfast, then put them away to charge at bedtime. She further stated the resident was upset because he could not hear well without the hearing aids. A review of the facility's policy and procedure, titled, Policy of Hearing Aid, undated, indicated, 1. Nursing will ask physician order in administering hearing aid. 2. Nursing will be the responsible in keeping the hearing aid. CNA (Certified Nursing Assistant) will collect the hearing aid at bedtime and give to LN (Licensed Nurse) for safekeeping, nursing AM shift (7 a.m. to 3 p.m.) will administer hearing aid after ADL care.

F 0686 Provide appropriate pressure ulcer care and prevent new ulcers from developing. Level of Harm - Minimal harm or potential for actual harm **NOTE- TERMS IN BRACKETS HAVE BEEN EDITED TO PROTECT CONFIDENTIALITY** Based on interview and record review, the facility failed to ensure necessary services were provided to promote healing of a pressure ulcer (damage to the skin and underlying tissues due to prolonged pressure) for one of two sampled residents (Resident 35) when: Residents Affected - Few 1. There were 8 days for which there was no documentation that Resident 35's pressure ulcer was treated; and 2. Resident 35's pressure ulcer assessment was incomplete. These failures had the potential to result in worsening of Resident 35's pressure ulcer. Findings: Review of Resident 35's medical record indicated she was admitted on [DATE] and had the diagnoses of dementia (mental disorder caused by brain disease or injury), spinal stenosis (narrowing of the spinal canal) osteoporosis (condition that causes bones to become brittle and fragile) and scoliosis (abnormal curvature of the spine). Review of Resident 35's 6/2022 treatment administration record (TAR) indicated she had a stage 3 pressure ulcer (full-thickness tissue loss) on her mid-back. The TAR indicated Resident 35 received daily pressure ulcer treatments from 6/10/22 to 6/14/22. There was no documentation that Resident 35 received any pressure ulcer treatments from 6/15/22 to 6/22/22. Further review of the TAR indicated Resident 35 started receiving daily pressure ulcer treatments again on 6/23/22. Review of Resident 35's Skin Only Evaluation, dated 6/14/22, indicated Resident 35's mid-back stage 3 pressure ulcer was still not healed. According to the evaluation, the pressure ulcer was 1.5 by 1.5 centimeters (cm, unit of measurement) in size and had a depth of 0.2 cm. The evaluation also indicated the wound had slough (substance consisting of blood cells, bacteria, dead tissue and other material) and serosanguineous (pink watery fluid) drainage. Review of Resident 35's Skin Only Evaluation, dated 6/23/22, indicated her mid-back pressure ulcer improved (despite the absence of treatment documentation from 6/15/22 to 6/22/22). The evaluation no longer indicated the presence of slough or drainage, and the wound had granulating tissue (healing surface of a wound). However, the section of the Skin Only Evaluation designated for wound measurements was left blank. During an interview and concurrent record review with licensed vocational nurse I (LVN I) on 2/24/23 at 8:23 a.m., she reviewed Resident 35's's medical record and confirmed there was no documentation that her pressure ulcer was treated from 6/15/22 to 6/22/22. LVN I acknowledged that Resident 35's pressure ulcer was still not healed during that time frame. LVN I also reviewed Resident 35's Skin Only Evaluation, dated 6/23/22, and confirmed it was incomplete because the section for wound measurements was left blank. During an interview and concurrent record review with the director of nursing (DON) on 2/24/23 at 10:29 a.m., she Reviewed Resident 35's medical record and confirmed there was no documentation of pressure ulcer treatments from 6/15/22 to 6/22/22.

F 0689 Level of Harm - Minimal harm or potential for actual harm Residents Affected - Few Ensure that a nursing home area is free from accident hazards and provides adequate supervision to prevent accidents. **NOTE- TERMS IN BRACKETS HAVE BEEN EDITED TO PROTECT CONFIDENTIALITY** Based on observation, interview, and record review, the facility failed to follow their fall management program for two of four residents (Residents 56 and 4) when: 1. Fall interventions were not implemented for Resident 56; and 2. No new interventions were developed and implemented after Resident 4 fell. These failures had the potential to result in further falls and/or injury to the residents. Findings: 1. Review of Resident 56's record indicated she was admitted to the facility with diagnoses including dementia (a group of symptoms affecting thinking and social abilities interfering with daily functioning) and bipolar disorder (mental disorder characterized by periods of elevated mood and depression, often with poor decision-making). Review of Resident 56's IDT Post Event Review, dated 12/22/22, indicated she had a fall on 12/22/22. Review of Resident 56's fall care plan indicated an intervention, initiated on 12/29/22, The resident uses silent alarm. Check for placement and functioning Q [every] shift. Review of Resident 56's IDT Post Event Review, dated 1/9/23 indicated she had a fall on 1/9/23. Review of Resident 56's fall care plan indicated an intervention, initiated on 1/10/23, Floor mat on both side[s] of the bed. During an observation on 2/23/23 at 8:49 a.m., Resident 56 did not have a fall mat on one side of her bed. One fall mat was folded and placed behind the head of her bed. During an observation on 2/23/23 at 1:13 p.m., Resident 56 did not have a fall mat on one side of her bed. One fall mat was folded on floor at foot of her bed. During an observation on 2/24/23 at 8:20 a.m., Resident 56 did not have a fall mat on one side of her bed. During an observation on 2/24/23 at 10:52 a.m., Resident 56 did not have a fall mat on one side of her bed. The fall mat was folded on floor at foot of her bed. During a concurrent observation and interview on 2/24/23 at 11:28 a.m., the director of nursing (DON) confirmed Resident 56 did not have a fall mat on one side of her bed and stated it was supposed to be there while she was in bed.

Review of the facility's policy, Falls Prevention and Management Program, last revised 12/2022, indicated the nursing function in a fall prevention program includes providing timely intervention to minimize risk. Residents Affected - Few 2. Review of Resident 4's medical record indicated she was admitted on [DATE] and had the diagnoses of dementia, bipolar disorder, and history of falling. Review of Resident 4's fall risk care plan, dated 1/16/19, indicated to encourage Resident 4 to use her call light for assistance and to ensure she was wearing appropriate footwear when walking with her walker. Review of Resident 4's Change in Condition Evaluation, dated 2/11/23, indicated she had a fall. There were no interventions documented on the Change in Condition Evaluation to prevent Resident 4 from falling again. Review of Resident 4's actual fall care plan, dated 2/12/23, indicated to encourage Resident 4 to use her call light for assistance and to make sure she wears non-skid shoes when walking (interventions that were already on Resident 4's 1/16/19 fall risk care plan). Review of Resident 4's Post Event Review, dated 2/13/23, indicated she had a fall on 2/12/23 (incorrectly dated, as the fall occurred on 2/11/23). There were no interventions documented on the Post Event Review to prevent Resident 4 from falling again. During an interview and concurrent record review with the DON on 2/24/23 at 10:00 a.m., she stated when a resident falls, the interdisciplinary team (IDT, staff from different disciplines who work together to plan and provide care) should develop and implement new interventions to prevent future falls. The DON reviewed Resident 4's medical record and confirmed that after the fall on 2/11/23, the IDT did not develop and implement any new interventions to prevent Resident 4 from falling again. Review of the facility's policy titled Fall Prevention and Management Program, revised 12/2022, indicated, The nursing function in a fall prevention program includes, but is not limited to .Being able to identify causative factors should a fall occur, and then accelerate the care plan with new interventions to prevent future falls.

F 0693 Level of Harm - Minimal harm or potential for actual harm Residents Affected - Few Ensure that feeding tubes are not used unless there is a medical reason and the resident agrees; and provide appropriate care for a resident with a feeding tube. **NOTE- TERMS IN BRACKETS HAVE BEEN EDITED TO PROTECT CONFIDENTIALITY** Based on observation, interview, and record review, the facility failed to develop a comprehensive policy for enteral feeding (the delivery of nutrients through a feeding tube directly into the stomach, duodenum, or jejunum) services, when there was no policy that indicated a consistent method that a licensed nurse should use for bolus feeding (the administration of a limited volume of enteral formula over brief periods of time). This failure had the potential to result in inconsistency of care and complications related to the G-tube and cause harm to the resident. Findings: A review of Resident 22's face sheet (a document that gives a resident's information at a quick glance, including contact details and a brief medical history), indicated the resident was admitted to the facility with diagnoses including Alzheimer's disease (a progressive disease that destroys memory and other important mental functions) and dysphagia (swallowing difficulties). A review of Resident 22's hospital Discharge summary, dated [DATE], indicated Resident 22 was admitted to the hospital on [DATE] for aspiration pneumonia (inflammation [swelling] and infection of the lungs or large airways that occurs when food or liquid is breathed into the airways or lungs, instead of being swallowed). A review of Resident 22's physician orders indicated, Diet: NPO (nothing by mouth), Enteral Feed: three times a day Enteral Feed Via Bolus Jevity [a nutritional formula] 1.5 @ 3 cans /day via PEG tube (G-tube) to provide 711/1067 kcal [kilocalorie, a unit of energy], 45 g pro[tein], 540 ml (milliliter, unit of measurement) free water. Give 1 can @ 8 AM 1 can @ 2 PM 1 can @ 6 PM. Enteral Feed: three times a day Flush with 30 ml H2O (water) before and after bolus feeding. During a concurrent interview and record review on 2/24/23, at 9:23 a.m., with registered nurse H (RN H), she was asked if the surveyor could observe her administering bolus feeding to Resident 22 when it was due. RN H informed the surveyor that she was a temporary agency staff, and this was her first time working in the facility. She stated she did not know Resident 22 was on bolus feeding. After reviewing Resident 22's electronic medication administration records (EMAR) and treatment administration records (TAR), RN H informed the surveyor that the tube feeding order was in the TAR, so she was not sure if she should administer it. RN H had to verify with the facility's treatment nurse, because usually the treatment nurse would take care of the orders in TAR. During an interview on 2/24/23, at 9:57 a.m., with RN H, she stated she would be the one to administer the bolus feeding, and she would do it right now for the 8:00 a.m. feeding. During the bolus feeding observation on 2/24/23, at 10:00 a.m., in Resident 22's room, RN H was observed. After checking stomach residual, RN H poured Jevity formula into cups, withdrew it into a 60 mL syringe, attached the syringe to the resident's G-tube, and administered the formula by pushing the syringe plunger to empty the contents into the G-tube without flushing the G-tube before the bolus feeding. RN H administered three syringes for a total of 180 mL of formula by pushing the plunger, then flushed the G-tube with 30 mL warm water by pushing the plunger.

Since Resident 22's bolus feeding order did not say administer by gravity, she used the push method. RN H confirmed she should have flushed the resident's G-tube with 30 mL of water before administering the bolus feeding. During an interview on 2/24/23, at 10:55 a.m., with the director of nursing (DON), she stated she was not able to find a policy that indicated the method for administering formula via G-tube, but the facility's standards of practice for bolus feeding should be by gravity. The DON confirmed RN H should not have used the push method to administer bolus feeding. The DON further stated RN H should have flushed the G-tube with 30 mL water before the feeding. A review of American society for Parenteral and Enteral Nutrition (ASPEN) Consensus Recommendation, titled, ASPEN Safe Practices for Enteral Nutrition Therapy, dated January 2017, indicated, 1. Develop policy and procedure documents for evidence-based practices to standardize the approach to and the administration of EN in all patient populations. 2.

F 0700 Level of Harm - Minimal harm or potential for actual harm Residents Affected - Some Try different approaches before using a bed rail. If a bed rail is needed, the facility must (1) assess a resident for safety risk; (2) review these risks and benefits with the resident/representative; (3) get informed consent; and (4) Correctly install and maintain the bed rail. Based on observation, interview, and record review, the facility failed to review the risks and benefits of bed rails (adjustable metal or rigid plastic bars that attach to the bed) with the resident or resident representative and obtain informed consent prior to the use of bed rails for seven of 27 residents (Residents 18, 23, 27, 37, 45, 55, and 363). This failure had the potential to put the residents at risk for entrapment and serious injury due to not being aware of the risks and benefits of bed rails. Findings: During the initial tour of the facility conducted on 2/21/23, at 9:30 a.m., Residents 18, 23, 37, 45, and 55, all had quarter bed rails elevated. During a concurrent interview and record review on 2/23/23, at 3:38 p.m., with the director of nursing (DON), when asked to show bed rail consents that indicated the facility reviewed the risks and benefits of bed rails with Residents 18, 23, 37, 45 and 55 or their legal representatives, the DON was unable to show the consents for those five residents. She stated the facility recently started to obtain bed rail consents in January of 2023. The DON explained bed rail consents were usually obtained during care plan conferences, and those five residents' care plan conferences were not due, so there were no bed rail consents for those residents. During an observation on 2/23/23, at 3:18 p.m., Resident 27 had quarter bed rails elevated. During an observation on 2/23/23, at 3:25 p.m., Resident 363 had quarter bed rails elevated. During a concurrent interview and record review on 2/24/23, at 3:16 p.m., with the DON, she was unable to show the bed rail consents for Residents 27 and 363. The DON stated both residents should have had informed consents for the use of bed rails. A review of the facility's policy and procedure, titled, Bed Safety, updated 3/28/17, indicated, [ .] 5. If side rails are used, there shall be an interdisciplinary assessment of the resident, consultation with the attending physician, and input from the resident and/or legal representative. 6. The staff shall obtain consent for the use of side rails from the resident or the resident's legal representative prior to their use. [ .] 9.

A random controlled medication use audit for two out of three residents (Residents 20 and 39) showed that medications were signed out of the Control Drug Record (CDR, an inventory sheet that keeps record of the usage of controlled medications), but were not documented as given to the residents on the medication administration record (MAR); and 2. Expired and discontinued controlled drugs were not removed from the medication cart. These failures had the potential to result in loss, misuse, and/or diversion of controlled medications. Findings: 1. The Controlled Drug Records (CDRs) for three (3) random residents receiving PRN (meaning as needed) controlled medications were requested for review during the survey. During a concurrent interview and record review with the director of nursing (DON) on [DATE] at 1:56 p.m., she stated any time a controlled medication was needed for a resident, the nurse would remove the medication from the medication cart, sign it out on the CDR (or the count sheet) to indicate it was removed, and document the administration on the MAR. a. Resident 20 had a physician's order, dated [DATE], for tramadol (a controlled medication for pain) oral tablet 50 milligrams (mg, unit of measurement), to give 25 mg by mouth every 8 hours as needed for pain. On [DATE] at 1:56 p.m., a review of Resident 20's CDR for tramadol 50 mg and the [DATE], [DATE], and February 2023 MAR with the DON indicated nursing staff signed out one (1) tablet on [DATE] at 3:00 p.m., [DATE] at 9:00 a.m., and on [DATE] at 12:30 p.m., but did not document on the MARs to show they were administered to the resident. The DON verified three missing documentations on the MAR to account for the tramadol tablets. b. Resident 39 had a physician's order, dated [DATE], for oxycodone (a potent controlled medication for moderate to severe pain) 5 mg, 1 tablet by mouth every 6 hours as needed for pain. During a concurrent interview and record review with the DON on [DATE] at 2:06 p.m., a review of Resident 39's CDR for oxycodone and the February 2023 MAR reflected the nursing staff signed out of the CDR but did not document the respective administration on the MAR on [DATE] at 2:58 p.m. The DON verified this finding and acknowledged one (1) oxycodone tablet was not accounted for. During a review of facility's policy and procedure titled Administering Medication, dated [DATE], it indicated, The individual administering the medication must initial the resident's MAR on the appropriate line after giving each medication and before administering the next ones.

Resident 27 received Abilify (an antipsychotic medication) when there were no specific target behaviors (behaviors intended to be reduced or eliminated by the medication) monitored. There was also no indication that Resident 27's behaviors presented a danger to herself or others, or caused significant distress to the resident. This failure put the resident at risk for experiencing adverse effects from unnecessary psychotropic medications such as dry mouth, blurred vision, urinary retention, constipation, heat intolerance, and tachycardia (abnormally rapid heart rate). Findings: A review of Resident 27's medical record indicated she was admitted to the facility with diagnoses including Alzheimer's disease (a progressive disease that destroys memory and other important mental functions), dementia (a group of conditions characterized by impairment of at least two brain functions, such as memory loss and judgement) without behavioral disturbance, psychotic disturbance, mood disturbance, anxiety (intense and persistent worry and fear), and major depressive disorder (condition that causes persistent feelings of sadness or loss of interest) A review of Resident 27's Minimum Data Set (MDS, an assessment tool), dated 1/5/22, indicated she had a brief interview for mental status (BIMS) score of 8 (a score of 8 to 12 indicates moderate cognitive impairment). The MDS indicated Resident 27 had no hallucinations (perceiving things that are not present), no delusions (false beliefs or judgements despite evidence to the contrary) and did not exhibit behaviors during the assessment period. Review of Resident 27's MDS, dated [DATE], indicated she had no hallucinations, no delusions, and did not exbibit behaviors during the assessment period. Review of Resident 's 27 medical record indicated she had been receiving Abilify in various doses since 1/7/19. Her current physician's order, dated 12/16/20, indicated Abilify 5 milligrams (mg, unit of dose measurement) 1 tablet by mouth at bedtime for unspecified Dementia with behavioral disturbance, visual hallucination. Review of Resident 27's care plan for psychotropic drug use, dated 4/12/19, indicated she was at risk for behavioral disturbances related to her diagnoses of Alzheimer's Disease and dementia manifested by visual hallucinations. The care plan further indicated, Pt [patient] on Abilify med per MD order. During an observation on 2/22/23 at 3:52 p.m., Resident 27 was sitting on her wheelchair with other residents near the facility elevator. She was very quiet and pleasant. During an interview with Licensed Vocational Nurse E (LVN E) on 2/22/23 at 3:52 p.m., she stated Resident 27 had no behaviors.

F 0851 Level of Harm - Minimal harm or potential for actual harm Residents Affected - Few Electronically submit to CMS complete and accurate direct care staffing information, based on payroll and other verifiable and auditable data. Based on interview and record review, the facility failed to submit complete and accurate direct care staffing information to the Centers for Medicare & Medicaid Services (CMS) for August of 2022. This deficient practice prevented the provision of complete and accurate direct care staffing information to the public. Findings: Review of the CMS PBJ (payroll-based journal) Staffing Data Report, dated 7/1/22 to 9/30/22, indicated the facility had no registered nurse (RN) hours from 8/1/22 to 8/31/22. The report also indicated for the same time period, the facility did not have licensed nursing coverage 24 hours a day. During an interview with the director of nursing (DON) on 2/24/23 at 2:42 p.m., she stated the information on the PBJ Staffing Data Report was not accurate.

The ADM provided a copy of an email from the SDRM explaining what happened. Review of the email from the SDRM to the facility, dated 1/31/23, indicated, I looked at the August [file] that was submitted and it has September dates instead of August dates. So the August and September files were the same and no August dates were submitted. During an interview and concurrent record review with the staffing coordinator (SC) on 2/27/23 at 10:38 a.m., she stated the reports indicating the facility did not have RN hours and licensed nursing staffing for August of 2022 were not accurate. The SC presented the staffing binder, which contained documentation that for August of 2022, the facility had RNs in the facility for at least 16 hours each day, and had licensed nurses in the facility 24 hours a day. Review of CMS's Electronic Staffing Data Submission Payroll-Based Journal Long-Term Care Facility Policy Manual Version 2.6, dated June 2022 indicated, Direct care staffing and census data will be collected quarterly, and is required to be timely and accurate.
