When You Hear Hoof Beats,Look for the Zebras: Atypical Presentation of Illness in the Older Adult

Nurse practitioners in acute, primary, and long-term care manage the complex needs of the geriatric population. Symptom presentation is fundamental to building the differential diagnosis. However, older adults often present atypically, for example, with only functional changes, rather than with typical symptoms. In order to identify potentially life-threatening illness in this group, it is necessary to have an understanding of symptom & exam alterations and the physiological age changes that underly them. By applying knowledge of these unique variations, nurse practitioners can help decrease mortality and morbidity in our older adult population.     

Facilitating Successful Aging: Encouraging Older Adults to Be Physically Active

Participation in regular physical activity has the potential to change the way we age. Evidence indicates that engaging in regular physical activity can provide dramatic physical, mental, and social benefits to older adults and decrease overall any-cause mortality. For older adults, the focus changes, and beside the promotion of health, maintenance of independent living becomes paramount. Nurse practitioners (NPs) must counsel older adults on the benefits of physical activity. The Stages of Change theory can be used to encourage older adults to change sedentary behavior and become more active.     

The impact of chronic low back pain on older adults: a comparative study of patients and controls

Chronic low back pain (CLBP) is one of the most common, poorly understood, and potentially disabling chronic pain conditions from which older adults suffer. Many older adults remain quite functional despite CLBP, and because age-related comorbidities often exist independently of pain (e.g., medical illnesses, sleep disturbance, mobility difficulty), the unique impact of CLBP is unknown. We conducted this research to identify the multidimensional factors that distinguish independent community dwelling older adults with CLBP from those that are pain-free. Three hundred twenty cognitively intact participants (162 with moderate pain for 3 months, and 158 pain-free) underwent comprehensive assessment of pain severity, medical comorbidity (illnesses, body mass index, medications), severity of degenerative disc and facet disease, lumbar flexion, psychological constructs (self-efficacy, mood, overall mental health), and self-reported as well as performance-based physical function. Significant differences were ascertained for all 22 measures. Discriminant function analysis revealed that eight measures uniquely maximized the separation between the two groups (self-reported function with the Functional Status Index and the SF-36, performance-based function with repetitive trunk rotation and functional reach, mood with the Geriatric Depression Scale, comorbidity with the Cumulative Illness Rating Scale and BMI, and severity of degenerative disc disease). These results should help to guide investigators that perform studies of CLBP in older adults and practitioners that want an easily adaptable battery for use in clinical settings.     

Functional capacity and self-care profiles of older people in senior care homes

The reduction of the functional capacity in older people is the result of physical, psychological and functional changes related to the ageing process, compromising the performance of daily life activities. Assessing their functional capacity and their self-care profile can facilitate the planning of targeted strategies related to stimulation, as well as cognitive and motor rehabilitation. This study aims to evaluate and analyse the functional capacity, as well as the level of dependence in self-care of older people in senior care centres. This is a transversal exploratory study, quantitative in nature. The sample was comprised of 313 participants, randomly selected from a set of senior care centres, with an average age of 83.41 (SD=7.14) years, recruited from the interior North of Portugal. The data collection instruments included the Barthel Index, the Lawton and Brody Scale, the Evaluation Form of Dependence in Self-care, the Self-care of Home Dwelling Elderly (self-care subscale profiles) and a questionnaire on demographic data. The elderly showed several levels of dependence on different self-care items. It was possible to observe that the staff often replaces the elderly in many of the tasks that could still be performed by them, and thus aggravates their levels of dependence. The link observed between functional capacity and self-care profiles highlights the need to focus on the notion of a healthy and active ageing process, especially in some profiles. The monitoring of the functional capacity and the self-care profile can provide knowledge concerning the potential for autonomy and individual needs, thus enabling targeted and more responsive interventions for the individual and the real needs of older people.     

BALANCE TRAINING FOR THE OLDER ATHLETE

As the older adult population increases in size, the number of older adults participating in sport activities will also likely increase proportionally with a concomitant increase in musculoskeletal injuries. Age-associated functional declines in muscle strength and the sensory systems, in addition to several other issues, contribute to reductions in balance that may increase fall risk There are a variety of ways to evaluate balance and fall-risk, and each older adult should be regularly screened in order to evaluate any changes in the ability to maintain postural stability. Balance training is a useful intervention in rehabilitation of postural stability impairments as well as in training programs for performance enhancement. One scientifically-based approach is Sensorimotor Training (SMT) which can be characterized as a progressive balance training program using labile surfaces to provide adequate and safe challenges to the older athlete''s balance. SMT addresses both static and dynamic components of balance as well as the multitude of systems that control balance in order to train effective strategies and elicit automatic postural responses in order to enhance postural stability. The authors believe that SMT should become part of the regular training regimen for the aging athlete. For the sport and orthopedic healthcare professional, an understanding of the physiologic changes that occur with age, the means by which balance can be assessed, and how SMT programs can be developed and implemented is crucial in addressing the growing number of older athletes that they will see.

Muscle force and range of motion as predictors of function in older adults

BACKGROUND AND PURPOSE: Musculoskeletal impairments and functional limitations are linked to disability in older adults. The purposes of this study were to identify the extremity musculoskeletal impairments that best predict functional limitations in older adults and to assess the validity of measurements obtained for the Physical Performance Test (PPT) as a predictor of disability. SUBJECTS AND METHODS: Eighty-one older adults residing in independent and dependent care facilities were tested for extremity muscle force, range of motion, and function. Data were analyzed using multiple regression analysis to identify extremity impairments that predicted function scores and logistic regression analysis to determine whether PPT scores predicted subjects' living situation as dependent versus independent. RESULTS: Subject age, lower-extremity muscle force, and lower-extremity range of motion explained 77% of the variance in function as measured by the PPT. Results differed when analysis was done by subject living situation, with a higher percentage of the variance in function scores explained by musculoskeletal measures for the dependent living group as compared with the independent living group. CONCLUSION AND DISCUSSION: Extremity musculoskeletal impairments have a strong relationship to function, especially in older adults living in dependent care settings. The results of this study can be used to design interventions to address the musculoskeletal disorders most related to function in the older population.     

Seeing the person behind the patient: enhancing the care of older people using a biographical approach

Recent policy statements have stressed the need for fundamental changes to the NHS, especially to the hospital care of older people. Person-centred care underpins such changes. If practitioners are to deliver person-centred care, then they need to learn more about the patient as an individual. One way that this might be achieved is through biographical approaches. This paper describes the findings of a developmental study undertaken over a 6-month period to investigate the introduction of a biographical approach to care on a unit in a NHS hospital. It concentrates on the views of the practitioners who used the approach. The study aimed to explore whether a biographical approach - in the form of storytelling - might be used to encourage person-centred practice. Using a practice development approach, the study explored the views of older people, their family carers and practitioners regarding their participation in life story work. Initial data were collected by focus groups with staff from a nursing home who regularly used life stories as a basis for care planning. Further data were collected through focus groups, semistructured interviews and observation - undertaken before and after the introduction of life story work - with older people, family carers and practitioners. Findings revealed that life stories helped practitioners to see patients as people, to understand individuals more fully and to form closer relationships with their families. Support workers also said how much they enjoyed using the approach to inform their care. Further longitudinal research is required to investigate biographical approaches more fully and to work more closely with practitioners to explore how biographical approaches can be undertaken as part of standard practice and be integrated into the culture and management of care.     

Functional trajectories of older acute medical inpatients

ObjectivesTo describe the changes in basic activities of daily living (BADL) function before and during hospital admission in older patients admitted to an acute medical unit and to assess the effect of age on loss of BADL function.MethodsProspective observational study. The study included 91 patients aged 65 and older consecutively admitted to an acute medical unit of an urban public teaching hospital in Portugal, between May and September 2017. Functional status was measured at three times: at hospital admission; at about 2 weeks before hospital admission (baseline); an on the discharge day. The functional condition was evaluated using the Katz index. Differences in scores for BADL between baseline and admission, between admission and discharge, and between baseline and discharge were used to define pre-admission, in-hospital and overall functional decline.ResultsPre-admission, in-hospital and overall functional decline occurred in 78.0%, 4.4% and 63.7% of the participants, respectively. In contrast, in-hospital functional improvement occurred in a minority of the patients (14.3%). Hospitalized older people are discharged with BADL function that is worse than their baseline function. The oldest patients are at high risk of poorer functional outcomes because they are less likely to recover BADL function lost before admission.ConclusionThese results emphasize the overriding need for implementing in-hospital processes to prevent functional decline and enhance functional recovery. This study also highlights the need for nurses to closely monitor the functional status of hospitalized older people, particularly in oldest-old patients.     

Age responses to multicomponent training programme in older adults

PURPOSE: The purpose of this study was to determine the effects of 9-week multicomponent training on the functional fitness of healthy older adults in different age groups. METHOD: Forty-two participants were randomly assigned and stratified by their age group: Training and Control Young Old Groups (TYOG, CYOG) (between 60-73 years), Training and Control Old Groups (TOG, COG) (between 74-86 years). The training programme consisted of three sessions per week of walking, strengthening, and flexibility exercises. A recently developed Functional Fitness Test battery to assess the physical parameters associated with independent functioning in older adults was performed before and after training. RESULTS: Training caused significant increases in all functional fitness tests in the TYOG and also in the TOG. There was no difference according to the absolute changes between TYOG and TOG due to the training (p>0.05). Training produced a significant improvement in chair sit and reach, arm curl, chair stand and 6 min walk test scores in the TYOG and TOG when they were compared to the control groups (p<0.05). CONCLUSION: Multicomponent training can produce substantial increase in functional fitness tests in young old adults and older adults and the rate of restoration of function is approximately similar in the two old age groups.     

Contraception for women over 40

Nurse practitioners can help women 40 and older make contraceptive choices that are effective, safe, and appropriate. The noncontraceptive benefits of some methods may be particularly relevant to women in this age group. Providing women with information about continuing fertility as they approach menopause and when it is safe to discontinue contraception may help to reduce unplanned pregnancies.     

Venous stasis wounds

Lower extremity wounds related to venous insufficiency are increasing. As the number of adults over the age of 65 increases, so do wounds related to changes in the vascular system. Venous stasis wounds can present as a real challenge to experienced practitioners. This article describes the many factors associated with venous wounds as well as the need for a comprehensive treatment plan.     

Aging and cancer

A substantial increase in the number of elderly people in the populations of developed nations in the coming years has been projected. Persons 65 years and older are at significantly higher risk of developing cancer when compared to younger individuals. There is a resulting increase in cancer incidence as well as mortality in this advanced age group. It is important to know how changes in physiological reserve and functional status in elderly patients, polypharmacy issues, comorbidities, and other age-related problems can affect cancer prognosis and management. Elderly patients are not adequately represented in clinical trials, thus creating a relative lack of information related to specific issues about elderly cancer patients and their care. Nevertheless, there is a substantial amount of guidance available, and in this review we will address selected issues of importance when considering the approach to the older cancer patient.     

Preventing coronary heart disease and stroke with aggressive statin therapy in older adults using a team management model

Purposes: The purposes of this review were to highlight recent clinical trial results on the safety and efficacy of statin therapy in adults aged 65 years and older and to examine how nurse practitioners (NPs) and physician assistants (PAs) working together with physicians as a team can better serve the needs of this fastest growing subset of the U.S. population who are at high risk for cardiovascular events including stroke.
Data sources: This report was compiled by reviewing the scientific literature on the safety and efficacy of statin therapy, including effects on cardiovascular, coronary, and stroke endpoints, with particular reference to clinical trial results in older patients.
Conclusions: Recent guidelines emphasize that age alone is not a reason to withhold treatment with statin therapy in older adults. However, despite the evidence highlighted in this review demonstrating that older patients can safely achieve substantial benefit from statin therapy, studies have consistently shown an inverse relationship between age and treatment propensity. Often, older patients have multiple risk factors and many chronic comorbid conditions that seem to complicate and hinder treatment in many busy clinic practices. More extensive guidelines for the use of statin therapy in older patients, incorporating recommendations for treatment targets and developing a framework for the use of statins in stroke prevention, would assist care providers in the management of this high-risk population. Finally, NPs and PAs are both well educated and well placed to manage patients with chronic stable cardiovascular disease (CVD).
Implications for practice: The implementation of a multidisciplinary team approach to identify at-risk individuals and provide them with education, counseling, and effective statin treatment will aid efforts to reduce the increased risk for morbidity and mortality associated with CVD in older adults.     

Critical care nursing for older adults: pathophysiological and functional considerations

The aging of the population brings into health care practice, including ICUs, an increasing prevalence of people with chronic conditions with corresponding expectations of eventual decline in function. These age-related health problems, however, do not have a precise moment of onset, nor a single and unambiguous cause. By their nature, chronic conditions do not have an end that can be modified easily, and ordinarily, they are related to parameters other than physiology alone. Aged individuals often are distinguished as a medicalized cohort on the basis of sheer numbers of comorbidities and predisposition toward frequent hospitalizations, without regard for the potential for adaptation to life despite complex health factors. Some care providers, health economists, and bioethicists propose using the existence of chronic conditions and assumed physical decompensation asa valid basis for restricting individuals and groups, by means of rationing, from consideration for intensive care and treatment.In view of studies demonstrating that covert rationing of ICU resources to critically ill older patients already is taking place, there isa need to continue to examine institutional policies that permit care providers to act as gatekeepers, ostensibly with benign intent, but presumably without patients' knowledge or acceptance. On the other hand, there is evidence that older ICU patients do equally well as younger and middle-aged patients in terms of discharge from the hospital with subsequent recovery of function. Thus, age alone is not a useful marker for limiting access to ICUs. Rather, a comprehensive evaluation is the foundation for diagnostic accuracy and health care decision-making for older individuals. Assessment and maintenance of the older person's functional status are fundamental concerns of geriatric and critical care specialists. Evaluation of an individual's baseline abilities in physical, mental, social, and psychological spheres is necessary before limitation of care realistically can be considered. Intensive care unit hospitalizations for catastrophic or critical illness are not necessarily terminal events. Ongoing functional assessment will help to illuminate the impact of chronicity on an older person's capacity for self care, and may help to guide health care decision-making regarding use of critical care resources. Accordingly, assuring equitable access to essential intensive care services, devoid of concerns about age constraints, will help to ensure the autonomy that is central to older adults' achievement of a fulfilling and productive old age.     

Leading the Way in Exercise and Diet (Project LEAD): intervening to improve function among older breast and prostate cancer survivors

The U.S. population is aging, bringing with it an increased prevalence of chronic disease and concomitant declines in physical function. The risk of developing cancer increases significantly with age, and functional decline is much more likely once a cancer diagnosis is rendered. Thus, functional status in later life is a key concern, one that is heightened among elders who have been diagnosed with cancer. To date, however, there have been few trials that have exclusively addressed issues related to cancer survivorship among older cancer patients, and to our knowledge, none has focused on preserving or enhancing physical functioning. This paper describes the study design and methodological considerations of a randomized controlled trial to determine if a personally tailored workbook and telephone counseling program can positively affect physical activity and dietary behaviors and ultimately the physical functioning of up to 420 older men and women newly diagnosed with breast or prostate cancer. This trial is unique because the cancer diagnosis is used not only as a marker of risk for functional decline, but also as a "teachable moment" - an opportune time when elders may be more receptive to making beneficial lifestyle changes. Undoubtedly, as cure rates for cancer increase and intersect with ever-growing numbers of elderly, there will be numerous opportunities to provide and test interventions within this vulnerable population and to target functional status as a primary outcome. In reporting our methods, we hope to give others "a leg up," so that they can hurdle with greater ease the barriers we experienced, and thus advance the field more rapidly.     

Functional Health Status of Older Women

By the year 2000 in the United States, there will be 32 million adults age 65 or over, representing 12% of the population, with the majority being women. Older women are experiencing greater longevity but worse overall health than men. The assessment of functional health status in older women is often neglected yet is the major contributor to independent living. Functional health status includes the dimensions of physical health, independent health, and psychosocial health. Studies of two different groups of non-institutionalized older women who reside in the same Southwestern state are discussed in relation to national study samples and implications for nurse practitioners.     

Cognitive training-related changes in hippocampal activity associated with recollection in older adults

Impairments in the ability to recollect specific details of personally experienced events are one of the main cognitive changes associated with aging. Cognitive training can improve older adults' recollection. However, little is currently known regarding the neural correlates of these training-related changes in recollection. Prior research suggests that the hippocampus plays a central role in supporting recollection in young and older adults, and that age-related changes in hippocampal function may lead to age-related changes in recollection. The present study investigated whether cognitive training-related increases in older adults' recollection are associated with changes in their hippocampal activity during memory retrieval. Older adults' hippocampal activity during retrieval was examined before and after they were trained to use semantic encoding strategies to intentionally encode words. Training-related changes in recollection were positively correlated with training-related changes in activity for old words in the hippocampus bilaterally. Positive correlations were also found between training-related changes in activity in prefrontal and left lateral temporal regions associated with self-initiated semantic strategy use during encoding and training-related changes in right hippocampal activity associated with recollection during retrieval. These results suggest that cognitive training-related improvements in older adults' recollection can be supported by changes in their hippocampal activity during retrieval. They also suggest that age differences in cognitive processes engaged during encoding are a significant contributor to age differences in recollection during retrieval.     

Benchmarking Functional Status in Older Adults

ObjectiveTo characterize the manner of functional status difficulties with age across multiple functional domains: lower extremity function, upper extremity function, and cognitive/social function. Construct validity of a functional status measure composed of these domains was assessed as part of this goal.DesignCross-sectional survey of the community-dwelling civilian population in the United States.SettingCommunity.ParticipantsCommunity-dwelling adults aged 60 years and older (N=7968).InterventionsNot applicable.Main Outcome MeasuresModel fit of a 20-item functional status measure to a confirmatory factor analysis model was assessed with the root mean square error of approximation and the root mean square residual. Functional status benchmarks for age were developed with curves plotting activity difficulty percentiles versus age for the general U.S. population.ResultsThe 20-item activity difficulty index modeled as a 3-factor construct had a root mean square error of approximation of .045 and a root mean squared residual of .052, indicating good fit. Benchmarks based on percentiles show that the median activity difficulty score is quite low for the full range studied but that there is a steady increase with increasing age. The domain regarding cognition and social function appeared to be less sensitive than the upper and lower extremity skills domains to increasing age.ConclusionsA broad measure of difficulty with functional activities can be meaningfully treated as a 3-domain construct. The scores represented by the index measuring this construct can be used to compare patients to a national sample of age-matched individuals to assess functional status using normative values.
