A nurse is assessing a client who has Stage 4 Alzheimers disease

This is one of many free activities.
Golden Carers has 1000s of activities and resources for senior care.

The importance of assessment in residential care settings cannot be underestimated. It underpins the philosophical approach to person-centred care, an ideology that provides clients with greater control and responsibility regarding their own health and lifestyle.

Why Do We Need to Assess Clients?

Every client entering residential care should be given a comprehensive assessment to identify individual needs, preferences, and strengths. The assessment is undertaken by an interdisciplinary team and covers various aspects of their’ lives such as: physical, spiritual, cognitive, social, mental, and emotional.

Client assessments lead to informed decisions that impact on care planning, resources allocation and other services.

The assessment process determines the most appropriate and effective way to support clients. Assessment usually starts soon after admission, however it depends of the organization and availability of staff.

Benefits of Conducting a Client Assessment

• Opportunity to get to know the client as an individual
• Establish areas of potential risk
• Ascertain a client’s preferences and needs
• Acknowledgement of cultural, religious, and ethnic values
• Advocate freedom of choice and independence

Who is involved in a Client Assessment?

A partnership between the interdisciplinary team and client is necessary to conduct a successful assessment.

Clients should be actively involved in their assessment as well as their family/ caregivers and close friends. In many organizations a case manager is assigned to support clients during the assessment process.

Leisure and Health staff are responsible for the Social/Spiritual Care Plan that includes recreation, relaxation, community trips, club affiliation, and other aspects of daily life.

Channels for Identifying Client Needs

• Interviews with the client/caregiver
• Daily observation of activities
• Consultation with co-workers from different shifts
• Volunteers (if applicable)
• Nurses assistants, physiotherapists, psychologists, and other allied health practitioners
• Kitchen staff, gardeners, administration staff
• “Social and Cultural Profile” (given to client/caregiver to fill in)

Identification of Needs Defined

Staff should address the needs of clients and their families in a holistic way. This means that the assessment focuses on the whole person and their entire well-being, including physical, emotional, spiritual, mental, social and environmental.

The Social & Spiritual Profile collects a client’s personal as well as confidential information that the facility may or may not share in the future and therefore should have secure storage.

Gathering information may require more than one meeting with clients.
Some of the customary ways in which the needs are identified include:

• Client interview
• Family/friend interviews
• Observation data gathering

Tips for conducting a Client Interview

Be supportive and non-judgemental to encourage cooperation.

• Explain to clients what you are trying to find out and why.
• Try to find a common interest to talk about or break the ice by observing something in or around where the interview is taking place e.g. pictures on the wall, a piece of furniture, magazines etc.
• Listen attentively and let clients talk; you may find out things you never thought about asking.
• Enquire about past hobbies and current preferred entertainment.
• Gently support your clients to take responsibility for their own problems/needs.
• Assist clients to set realistic goals (priority goals, long-term or short-term goals?)

Tips for Conducting Family/Friend Interviews

Talking to family and friends may provide useful information about clients. Use discretion and be courteous.

• Establish current family’s dynamics and lifestyle.
• Encourage participation in facility’s activity programs (concerts, major events, and bus trips).
• Seek advice and recommendations regarding relative’s care preferences.
• Provide information about the range of activities and choices available through the recreation program.
• Liaise with family when developing care plan.
• Invite family to attend/join bi-monthly ‘Residents’ & Relatives Meeting’.
• Invite relatives to participate in ‘Family Council Meetings’ (if applicable), to share concerns.

Tips for Gathering Information through Client Observation

• Observe client interactions with peers at meal times.
• Take note of verbal and non-verbal communication.
• Notice client’s mobility during the day e.g. able to sit down but needs assistance to stand up, unable to go to the toilet alone, able to drink from cup but not able to pour drink.
• Classify recreation assistance required e.g. supervision, escorting, extra support, wheelchair required.
• Consult other employees that come into contact with client e.g. domestic staff, gardeners, volunteers, Chaplains, and others

Some Useful Questions to Ask

• Explore what aspect of their profession they enjoyed.
• Find out what abilities clients have or lack that affects social/leisure activities? e.g.
  • Physical: mobility, dexterity
  • Sensory: vision/hearing impaired
  • Cognitive; attention span, behaviour, dementia status.
• Cultural background: would they like access to ethnic radio, special religious service, affiliation with clubs related to their background?
• Observe client personalities e.g. loners, extroverts, fun loving, melancholic.
• Seek recommendations from caregivers/clinical health providers regarding clients with specific needs (Alzheimer's Disease, vision deficiency, emotional needs.)
• What type of activity is more suitable: active or passive?
• What hobbies/craft/music and other activities would appeal to them?
• What barriers, real or perceived, could affect social/leisure activities? E.g. unmet emotional needs, family estrangement, painful memories, mobility issues, depression, and other issues.
• What strengths do clients have? What remaining abilities can be improved upon?
• How can a client’s spiritual well being be supported?

Next Step: Developing a Care Plan

Before developing a care plan, it is important that staff communicate with other health practitioners to gather information outside the scope of their own roles e.g. behaviour management, psychological issues, and special dietary requirements amongst others.

Learning Outcome

1. Describe the symptoms of AD

2. Recall the management of a patient with AD

3. Describe the cognitive issues in AD

4. Summarize the role of nurses in managing AD

Dementia is a general term that refers to a decline in cognitive ability severe enough to interfere with activities of daily living. Alzheimer disease (AD) is the most common type of dementia, accounting for at least two-thirds of cases of dementia in people age 65 and older. Alzheimer disease is a neurodegenerative disease that causes progressive and disabling impairment of cognitive functions including memory, comprehension, language, attention, reasoning, and judgment. It is the sixth leading cause of death in the United States. Alzheimer disease is typically a disease of old age. Onset before 65 years of age (early onset) is unusual and seen in less than 10% of Alzheimer disease patients. The most common presenting symptom is selective short-term memory loss. The disease is invariably progressive, eventually leading to severe cognitive decline. There is no cure for Alzheimer disease, although there are treatments available that may improve some symptoms.

Symptoms of Alzheimer disease depend on the stage of the disease. Alzheimer disease is classified into preclinical, mild, moderate, and late-stage depending on the degree of cognitive impairment. The initial presenting symptom is usually recent memory loss with relative sparing of long-term memory and can be elicited in most patients even when not the presenting symptom. Short-term memory impairment is followed by impairment in problem-solving, judgment, executive functioning, lack of motivation and disorganization, leading to problems with multitasking and abstract thinking. In the early stages, impairment in executive functioning may be subtle. This is followed by language disorder and impairment of visuospatial skills. Neuropsychiatric symptoms like apathy, social withdrawal, disinhibition, agitation, psychosis, and wandering are also common in mid to late stages. Difficulty performing learned motor tasks (dyspraxia), olfactory dysfunction, sleep disturbances, extrapyramidal motor signs like dystonia, akathisia, and parkinsonian symptoms occur late in the disease. This is followed by primitive reflexes, incontinence, and total dependence on caregivers.[1],[2],[3]

Nursing Diagnosis

• Unable to perform daily living activities

• Loss of bladder and bowel control

Alzheimer disease is a gradual and progressive neurodegenerative disease caused by neuronal cell death. It typically starts in the entorhinal cortex in the hippocampus. There is a genetic role identified for both early and late-onset Alzheimer disease. Several risk factors have been associated with Alzheimer disease. Increasing age is the most important risk factor for Alzheimer disease. Traumatic head injury, depression, cardiovascular and cerebrovascular disease, higher parental age, smoking, family history of dementia, and presence of APOE e4 allele are known to increase the risk of Alzheimer disease. Higher education, use of estrogen by women, use of anti-inflammatory agents, and regular aerobic exercise is known to decrease the risk of Alzheimer disease. Having a first-degree relative with Alzheimer disease increases the risk of developing Alzheimer disease by 10% to 30%. Individuals with 2 or more siblings with late-onset Alzheimer disease increases their risk of getting Alzheimer disease by 3-fold as compared to the general population.[4],[5],[6]

Alzheimer disease is typically a disease of old age. The global prevalence of dementia is reported to be as high as 24 million and is predicted to increase 4 times by the year 2050. Estimated health care cost of Alzheimer disease is $172 billion per year in the United States alone. In 2011, the United States had an estimated 4.5 million people age sixty-five and above, living with clinical Alzheimer disease. The incidence of dementia is predicted to double every 10 years after 60 years of age. Age-specific incidence increases significantly from less than 1% per year before 65 years of age to 6% per year after 85 years of age. Incidence rates of Alzheimer disease are slightly higher for women, especially after 85 years of age.

A good history and physical examination are the keys to diagnosis. It is also essential to take a history from the family and caregivers as some patients may lack insight into their disease. It is vital to characterize onset and early symptoms to differentiate from other types of dementia. It is important to obtain a good assessment of functional abilities like basic and individual activities of daily living.

A complete physical examination with a detailed neurological exam and mental status examination is needed to evaluate disease stage and rule out other conditions. Comprehensive clinical assessment can provide reasonable diagnostic accuracy in most patients.  A detailed neurological examination is essential to rule out other conditions. In Alzheimer disease, the neurological exam is usually normal. A mental status examination should assess concentration, attention, recent and remote memory, language, visuospatial functioning, praxis, and executive functioning.

Brief standard examinations like the mini-mental status examination are less sensitive and specific, although they can be used for screening.

All follow-up visits should include a full mental status examination to evaluate disease progression and development of neuropsychiatric symptoms.

Routine laboratory tests show no specific abnormality. Complete blood count (CBC), complete metabolic panel (CMP), thyroid-stimulating hormone (TSH), B12 are usually checked to rule out other causes.[7],[8],[9]

Brain imaging may help in the diagnosis and monitor clinical course of the disease. MRI or CT brain can help exclude other causes of dementia like stroke or tumors. Dilated lateral ventricles and widened cortical sulci, especially in the temporal area are typical for Alzheimer disease.

Cerebrospinal fluid (CSF) is usually normal, but total protein may be mildly elevated. Measurements of total-tau, beta-amyloid, and phosphorylated tau protein are sometimes helpful for differential diagnosis. Alzheimer disease is strongly predicted if CSF has decreased beta-amyloid 42 and increased tau protein.

EEG typically shows a generalized slowing with no focal features.

Most reliable method to detect mild cognitive impairment in early disease is neuropsychological testing.

More recently, volumetric MRI is being used to precisely measure volumetric changes in the brain. In Alzheimer disease, volumetric MRI shows shrinkage in the medial temporal lobe. However, hippocampal atrophy is also linked to normal age-related memory decline, so the use of volumetric MRI for early detection of Alzheimer disease is questionable. A definite role for volumetric MRI to aid diagnosis of Alzheimer disease is not fully established yet.

Functional brain imaging techniques like PET, fMRI, and SPECT are being used to map patterns of dysfunction in smaller brain areas of the medial temporal lobe. These studies may be helpful in early detection and monitoring clinical course; however, their role in the diagnosis of Alzheimer disease is not fully established yet.

Most recently, there have been developments in brain imaging techniques to detect core histological features of Alzheimer disease, that is amyloid plaques and neurofibrillary tangles. The utility of these techniques is still being investigated.

Genetic testing is usually not recommended for Alzheimer disease. It may sometimes be used in families with rare early-onset forms of Alzheimer disease.

It is important to understand that diagnosing the type of dementia with all certainty may not be entirely possible despite excellent clinical history, physical examination and relevant testing. Some patients will complain of cognitive impairment that can be verified objectively, but is not severe enough to impair activities of daily life and thus does not meet criteria for dementia, and is usually just classified as mild cognitive impairment. However, a significant proportion of people with mild cognitive impairment will develop dementia of some type in 5 to 7 years.

There is no cure for Alzheimer disease. Only symptomatic treatment is available.[10][11][12]

Two categories of drugs are approved for treatment of Alzheimer disease: cholinesterase inhibitors and partial N-methyl D-aspartate (NMDA) antagonists.

Cholinesterase Inhibitors

Cholinesterase inhibitors act by increasing the level of acetylcholine; a chemical used by nerve cells to communicate with each other and is important for learning, memory and cognitive functions. Of this category, 3 drugs: donepezil, rivastigmine, and galantamine are FDA-approved for treatment of Alzheimer disease.

Donepezil can be used in all stages of Alzheimer disease. Galantamine and rivastigmine are approved for treatment in mild to moderate Alzheimer disease only. Donepezil and galantamine are rapid, reversible inhibitors of acetylcholinesterase. Rivastigmine is a slow, reversible inhibitor of acetylcholinesterase and butyrylcholinesterase. Donepezil is usually preferred of all because of once-daily dosing. Galantamine is available as a twice daily tablet or as a once-daily extended-release capsule. It cannot be used in end-stage renal disease or severe liver dysfunction. Rivastigmine is available in an oral and transdermal formulation. Most common side effects of cholinesterase inhibitors are gastrointestinal-like nausea, vomiting, and diarrhea. Sleep disturbances are more common with donepezil. Due to increased vagal tone, bradycardia, cardiac conduction defects, and syncope can occur, and these medications are contraindicated in patients with severe cardiac conduction abnormalities.

Partial N-Methyl D-Aspartate (NMDA)  Memantine

Partial N-Methyl D-aspartate (NMDA) antagonist memantine blocks NMDA receptors and slows intracellular calcium accumulation. It is approved by FDA for treating moderate to severe Alzheimer disease. Dizziness, body aches, headache, and constipation are common side effects. It can be taken in combination with cholinesterase inhibitors.[13]

It is also important to treat anxiety, depression, and psychosis, which is often found in mid to late stages of Alzheimer disease.

Environmental and behavioral approaches are beneficial especially in managing behavioral problems. Simple approaches such as maintaining a familiar environment, monitoring personal comfort, providing security object, redirecting attention, and avoiding confrontation can be very helpful in managing behavioral issues.

The expected benefits of treatment are modest. Treatment should be stopped or modified if no significant benefits or if intolerable side effects.

Regular aerobic exercise has been shown to slow the progression of Alzheimer disease.

Nursing Management

• Obtain thorough history and physical exam

• Assess neurological and psychiatric status

• Check behavior, nutrition ability to dress

• Ensure adequate nutrition

• Ensure patient is oriented

• Provide structure and maintain schedule

• Assist with daily living activities

• Encourage interaction with others

• Educate family or caregiver about disease progression and available resources

When To Seek Help

Outcome Identification

• Has a  decent quality of life

• Is oriented and responsive

Monitoring

• Neurological and mental health status

Alzheimer disease (AD) is a progressive neurodegenerative disorder marked by behavior and cognitive impairment that eventually interfere with daily functional living activities. The disorder has no cure, and its rate of progression is variable. Further, the diagnosis of Alzheimer disease in the early phase is difficult, and there are no specific laboratory or imaging tests to confirm the diagnosis. The drugs available to treat the condition only work for the mild disease but also have numerous side effects which are not well tolerated. Alzheimer disease is a systemic disorder and creates havoc in the family. These individuals often wander, fall, have significant behavior problems and loss of memory. The majority of patients end up in an institution because they become unmanageable at home. Because of the nature of the disease, an interprofessional approach to the disorder has been recommended. Many guidelines and recommendations have been made on how to approach, monitor and treat Alzheimer patients. No one measure can prevent or arrest the disease. Given this, the following health care workers have a critical role in ensuring that the patient with Alzheimer disease remains safe and lead a decent quality of life.

Physical therapy for exercise. There is now ample evidence that exercise can help reduce the progression of the disease.[14] (Level III)

Nurses to educate the patient and family on medications, lifestyle changes, and performing daily living activities. To educate the partner on self-reporting on the worsening of symptoms.

Pharmacist to ensure that polypharmacy does not occur and that the patient is not developing adverse effects.

Outcomes

Alzheimer disease is initially associated only with impaired memory, but with time, the individual may develop severe cognitive and behavioral symptoms like depression, anxiety, anger, irritability, insomnia, and paranoia. As the disease progresses most of them will require assistance with daily living activities. Eventually, even walking become difficult and many may not be able to eat or develop swallowing difficulties that lead to aspiration pneumonia.

The time from diagnosis to death is variable; some individuals may die within five years, and others may remain alive for ten years, but overall the quality of life is very poor. While an interprofessional approach to management of Alzheimer patients is recommended, an analysis of several studies reveals that this approach has no impact on the care of his patients. However, because of the heterogeneity in the previous studies, more robust studies will be required to determine what type of approach works best for managing these patients.[15]

Health Teaching and Health Promotion

• Educate caregiver and family about prognosis and support systems

• Provide the name and contact information for a social worker

Educate the family and caregiver about the support systems
