Best practices are expected when providing quality home health care to heart failure patients. According to the American Heart Association, there are over 5 million cases of heart failure (HF) in the US, with an average 500,000 cases, diagnosed annually. It ranks as the primary and secondary diagnoses for all hospitalizations over the age of 65. The financial burden is in excess of $40 billion, annually, in direct and indirect costs.
Heart failure patients are among those most visited in home health care and among the five most prevalent diagnoses of homecare patients (per VNAA Chronic Care Clearinghouse). A cardiac assessment is often the primary nursing skill for homebound patients diagnosed with heart failure and involves specific knowledge of nutrition, pharmacotherapy, exercise, coping skills, and risk management. Because caring for cardiac patients is frequent, many agencies rely on the clinician’s expertise regarding assessment and planning, yet research is suggesting the establishment of agency protocols is in order.
Pathophysiology
Heart failure may occur when damage is done to the heart preventing it from adequately pumping blood to tissues to meet required metabolic needs. Because the circulatory system carries oxygen and necessary nutrients, a decreased blood flow limits needed tissue nourishment, resulting in compensation by the body as it seeks balance or homeostasis. The body is forced to stimulate the sympathetic nervous system to increase both the heart rate and blood pressure to meet oxygen and nutrient requirements. The kidneys will assist, by a process of vasoconstriction, within the tubules, to increase blood pressure and secondarily retaining and reabsorbing sodium to increase vascular pressure that will aid in also raising blood pressure. In the short term, this is effective. However, long term effects include cardiac decompensation and increased symptoms of heart failure.
Symptoms frequently seen during exacerbations
Per HHQI, Best-Practice Disease Management: Heart Failure Intervention Package, expect to see
- Shortness of breath
- Decreased urination
- Chest pain or heaviness
- Increased weakness or fatigue
- Edema of the feet, ankles, hands, abdomen, or sacrum (anasaca)
- Increase in weight of 2-3 pounds in 24 hours or 3 pounds in one week
- Dry hacking cough or cough producing a white foamy sputum
- Orthopnea (the number of pillows needed propped up to breath comfortably)
- Paroxysmal nocturnal dyspnea (feeling of smothering or fullness in the chest when lying down and resolves when standing up).
An effective in-home prevention and treatment plan helps the patient control symptoms. It also helps control the costs associated with heart failure by reducing the need for emergent and/or inpatient care. Since heart failure patients are among those most often seen in emergent and inpatient settings, a home health clinical specialty heart failure program is necessary for cardiac patients to reduce this incidence. This care is a focus of CMS. New Survey Protocols, effective May 1, 2011, focus on data gathering and outcomes seen, as opposed to the focus on structure and process orientation of past surveys. Care planning and delivery with resulting outcomes of all patients will be the focus, but because heart failure is of growing incidence, expect scrutiny.
As the OASIS process measure begins to produce data, one can expect to see the evaluation and adjustment of processes brought to the forefront. Agencies must consider a specialized episode and disease management plan for heart failure patients under care. This program will assist the agency reach its goals clinically, operationally, and financially.
The CMS OASIS data items were created to measure processes of care in several areas to reflect Institute of Medicine (IOM) goals and Medicare Payment Advisory Commission (MPAC) recommendations. It was felt there is a need to focus on high-risk, high-volume, chronic conditions seen in the home health setting and although CMS indicates that the integrated OASIS-C process items are optional practices, it is believed by industry specialists and content experts that identified best practices are critical to providing efficient quality home health care with expected/predictable outcomes.
Evidence-based best practices
The rationale behind process data elements is to encourage agencies to incorporate evidence-based practices (EBP) into processes. One definition of EBP is to use the best scientific evidence available as a tool to guide clinical decision-making for the purpose of attaining the best outcomes.
Research supports that a combination of proper acute care discharge planning and post discharge care for patients with heart failure can significantly reduce hospital readmission rates, improve quality of life, and reduce cost of care. Heart failure evidence-based standards of care per the American College of Cardiology/American Heart Association (ACC/AHA) include:
- Assessment for fluid retention via monitoring weight and abdominal girth.
- Assessment of activity level, perceived dyspnea, fatigue, reduced exercise tolerance, sleep patterns, and patient’s activity that triggers dyspnea.
- BP standing/sitting, heart rate (HR), respiratory rate (RR), jugular venous distention (JVD) every visit.
- Assess edema and instruct the patient as to obtaining daily weight and complete a patient assessment of abdominal and peripheral swelling, focusing on feet/ankles, hands, sacrum, scrotal area, and abdomen.
- Complete auscultation of heart and lung sounds; identify S3 or S4. Assess for new or recurrent dysrhythmias or murmurs. Per HHQI “changes in heart rhythm can lead to poor cardiac output and worsening heart failure. Note: Extra sounds can be a warning of impending heart failure exacerbation.”
- Assess lung sounds to identify any changes or note wheezes, crackles, rhonchi, or diminished breath sounds.
- The physician may well monitor serum electrolytes/renal function every 6 months.
- Assess appetite. Expect the physician to order a low-fat, low-sodium diet; fluid restriction. When assessing appetite, look for signs of abdominal fluid retention such as feelings of abdominal fullness and early satiety. Refer to girth baseline and successive measurements.
- Assess for orthopnea and paroxysmal nocturnal dyspnea. Verify number of pillows used when lying down. Both of these symptoms are usually intermediate signs of fluid retention and per HHQI, “intervention at this point could still prevent re-hospitalization.”
- A thoracic impendence reading (ZO) may be ordered. Fluid status changes can signify need for intervention and possibly prevent a hospitalization.
- Assess urinary output. Decreased output could signal impending signs of renal failure or heart failure decompensation, as the body attempts to raise blood pressure.
- Assess diabetes control, if applicable.
- Assess psychosocial coping and note symptoms of depression. Assess family and support systems. Depression intervention may be necessary to maintain optimum self care-management.
- If ordered, encourage regular walks progressing to 1 hour per day 3-5 days per week..
- Smoking: Discourage first-hand and second-hand smoke.
Agency Administrators
Administrators who are looking to establish a cardiac program in their agency should review the HHQI “Best Practice Disease Management: Heart Failure.” This Nurse Track is a Best-Practice Disease Management intervention package that supports the implementation, education, and application of current assessment and symptom management modalities with clinical processes to decrease active symptoms in heart failure patients. It discusses providing a structured plan for care, and supports EBP. The package describes nursing actions that support an effective disease management program.
The administrator should also include an assessment of current standards of care in relation to the number of visits incurred as well as type and depth of education provided to patients, along with early intervention for symptoms of heart failure. Once the assessment plan is completed, a review of nursing education gaps assessed, agency-wide education must occur to ensure that all clinicians are familiar with best-practice standards and provide opportunity for feedback. After that education is provided and the standards are implemented, outcomes should be analyzed, and ongoing auditing for compliance should be established to ensure the best practice standards are maintained.
Guidelines in Best-Practices for Administrators
There are many programs available regarding best-practices for care of patients with heart failure. The HHQi site offers RNs a free 2.0 Continuing Nursing Education units after completion of the 115 minute five activities for the Heart Failure Track. In addition, there are tools and podcasts to aid in reducing hospitalizations as well as a Decision Support Tool: Heart Failure
Once the program is underway, data analysis becomes an important practice allowing the administrator to review statistics and trends within the agency-specific patient populations. For the administrator planning to survive present and anticipated future changes in regulation, care delivery, and reimbursement models effective decision-support software providing data aggregation, benchmarking, and analysis opportunities for operational management will be essential.
Administrators should monitor specific patient populations for trending and analysis that include:
- Hospitalization rates by diagnoses
- Disciplines utilized within an episode
- Visit patterns and scheduling
- Number of days from SOC before therapy began care
- Average number or recertifications
- Therapy utilization for energy conservation training
- Changes in patient education between SOC and recertification episode
In addition to monitoring heart failure outcomes through OASIS-C data, reduced hospitalization rates, compliance with the structured heart failure disease management program the agency should find ways to motivate personnel to continue use of the enhanced heart failure education. Administrators should be certain a specific skilled staff competency review regarding heart failure symptoms is administered regularly.
Best practices disease management programs can be very successful as seen in Dominion Care Home Health agency in San Antonio, TX. Their acute care hospitalization (ACH) rate declined from 41% to 28% after initiating such a program. With pay for performance in our future, newly instituted Survey Protocols, and higher expectations for improved patient outcomes, a disease management program targeting heart failure is a must.
