CE: Original Research: New Acute Symptoms in Older Adults with Cognitive Impairment: What Should Family Caregivers Do?

: Background: When older adults with cognitive impairment develop new physical or behavioral symptoms, their family caregivers face a difficult decision: whether and when to seek professional medical care. Most family caregivers lack formal training in assessment and may have difficulty making such decisions. The Veterans Health Administration's home-based primary care (HBPC) program, which is widely available, offers community-dwelling frail veterans and their family caregivers guidance, with the goal of reducing hospitalization and institutionalization in long-term care facilities. OBJECTIVE: This study sought to assess the frequency with which family caregivers of cognitively impaired older adults sought prehospital guidance from health care professionals when that resource was available to them, and to describe the characteristics of such events. METHODS: This study used a retrospective chart review of patients who were enrolled in the Orlando Veterans Affairs Medical Center HBPC program for at least one month between October 1, 2013, and September 30, 2014; had a diagnosis indicative of cognitive impairment (Alzheimer's disease, vascular dementia, or mild cognitive impairment); had a dedicated family caregiver; and were not enrolled in hospice care. Data were collected from data collection templates and nurses' narrative notes. Univariate descriptive analyses were conducted regarding the type of staff contacted by family caregivers, the presenting diagnoses, the guidance offered by staff, and the number of unplanned acute care encounters. RESULTS: Among the 215 patients studied, there were 254 unplanned acute care encounters (including ED visits followed by discharge to home and ED visits resulting in hospital admission). Family caregivers sought guidance from a health care professional 22% of the time before such an encounter. The presenting clinical issues were most often new problems (43%) that included falls, feeding tube problems, fever, new pain, rash or other skin problems, and unexplained edema. Overall, 25% of all unplanned acute care encounters were for reasons considered potentially avoidable. About half of the patients who were subsequently hospitalized had symptoms of delirium, indicating that their illness had significantly advanced before presentation. CONCLUSIONS: It's important for health care professionals to ensure that family caregivers of cognitively impaired older adults can access professional guidance readily when facing decisions about a loved one's care, especially when there is an acute onset of new symptoms. Teaching caregivers how to recognize such symptoms early in order to prevent exacerbations of chronic illness and subsequent hospitalization should be a high priority. Our findings underscore the need to do so, so that caregivers can best use the resources that HBPC programs have (or ought to have) in place, in particular 24/7 guidance and decision assistance.

Measuring agreement between healthcare survey instruments using mutual information.

BACKGROUND: Healthcare researchers often use multiple healthcare survey instruments to examine a particular patient symptom. The use of multiple instruments can pose some interesting research questions, such as whether the outcomes produced by the different instruments are in agreement. We tackle this problem using information theory, focusing on mutual information to compare outcomes from multiple healthcare survey instruments. METHODS: We review existing methods of measuring agreement/disagreement between the instruments and suggest a procedure that utilizes mutual information to quantitatively measure the amount of information shared by outcomes from multiple healthcare survey instruments. We also include worked examples to explain the approach. RESULTS: As a case study, we employ the suggested procedure to analyze multiple healthcare survey instruments used for detecting delirium superimposed on dementia (DSD) in community-dwelling older adults. In addition, several examples are used to assess the mutual information technique in comparison with other measures, such as odds ratio and Cohen's kappa. CONCLUSIONS: Analysis of mutual information can be useful in explaining agreement/disagreement between multiple instruments. The suggested approach provides new insights into and potential improvements for the application of healthcare survey instruments.

Licensed Nurse and Nursing Assistant Recognition of Delirium in Nursing Home Residents With Dementia.

Many nursing home residents experience delirium. Nursing home personnel, especially nursing assistants, have the opportunity to become familiar with residents' normal cognitive function and to recognize changes in a resident's cognitive function over time. The purpose of this study was to determine the accuracy of delirium recognition by licensed nurses and nursing assistants from eight nursing homes over a 12-month period. Participants were asked to complete five case vignette assessments at three different time points (in 6-month intervals) to test their ability to identify different subtypes of delirium and delirium superimposed on dementia (DSD). A total of 760 case vignettes were completed across the different time points. Findings reveal that staff recognition of delirium was poor. The case vignette describing hyperactive DSD was correctly identified by the greatest number participants, and the case vignette describing hypoactive DSD was correctly identified by the least number of participants. Recognition of the case vignette describing hypoactive delirium improved over time. Nursing assistants performed similarly to the licensed nurses, indicating that all licensed nursing home staff require further education to correctly recognize delirium in older adults.

Delirium superimposed on dementia is associated with prolonged length of stay and poor outcomes in hospitalized older adults.

BACKGROUND: Current literature does not identify the significance of underlying cognitive impairment and delirium in older adults during and 30 days following acute care hospitalization. OBJECTIVE: Describe the incidence, risk factors, and outcomes associated with incident delirium superimposed on dementia. DESIGN: A 24-month prospective cohort study. SETTING: Community hospital. PATIENTS: A total of 139 older adults (>65 years) with dementia. METHODS: This prospective study followed patients daily during hospitalization and 1 month posthospital. Main measures included dementia (Modified Blessed Dementia Rating score, Informant Questionnaire on Cognitive Decline in the Elderly), daily mental status change, dementia stage/severity (Clinical Dementia Rating, Global Deterioration Scale), delirium (Confusion Assessment Method), and delirium severity (Delirium Rating Scale-Revised-98). All statistical analysis was performed using SAS 9.3, and significance was an α level of 0.05. Logistic regression, analysis of covariance, or linear regression was performed controlling for age, gender, and dementia stage. RESULTS: The overall incidence of new delirium was 32% (44/139). Those with delirium had a 25% short-term mortality rate, increased length of stay, and poorer function at discharge. At 1 month follow-up, subjects with delirium had greater functional decline. Males were more likely to develop delirium, and for every 1 unit increase in dementia severity (Global Deterioration Scale), subjects were 1.5 times more likely to develop delirium. CONCLUSIONS: Delirium prolongs hospitalization for persons with dementia. Thus, interventions to increase early detection of delirium have the potential to decrease the severity and duration of delirium and to prevent unnecessary suffering and costs from the complications of delirium and unnecessary readmissions to the hospital.

Comorbidities in the context of care transitions.

The growing number of individuals with comorbidities experiencing care transitions represents a challenge to the current health care system. A qualitative study of empirical literature, using the Dimensional Analysis approach, was conducted to elucidate the theoretical underpinnings of the phenomenon of individuals with comorbidities undergoing care transitions. The findings were arranged in a novel schematic demonstrating that the relationship among individual attributes, comorbidities, and care processes informed the individual's risk for adverse outcomes. This schematic is useful for future nursing research studies evaluating innovative programs implemented to improve health outcomes among vulnerable populations undergoing care transitions.

Screening for delirium using family caregivers: convergent validity of the Family Confusion Assessment Method and interviewer-rated Confusion Assessment Method.

OBJECTIVES: To explore agreement between the Family Confusion Assessment Method (FAM-CAM) for delirium identification and interviewer-rated CAM delirium ratings. DESIGN: Exploratory analysis of agreement. SETTING: Community. PARTICIPANTS: Fifty-two family caregivers and 52 elderly adults with preexisting impairment according to standardized cognitive testing. MEASUREMENTS: The interviewer-rating for delirium was determined by fulfillment of the CAM algorithm RESULTS: The total sample included 52 paired CAM:FAM-CAM assessments completed across 52 dyads of elderly adults with preexisting cognitive impairment and family caregivers. The point prevalence of delirium was 13% (7/52). Characteristics did not differ significantly between the groups with and without delirium. The FAM-CAM questions that mapped directly to the original four-item CAM algorithm had the best overall agreement with the interviewer-rated CAM (kappa = 0.85, 95% confidence interval (CI) = 0.65-1.0), sensitivity of 88% (95% CI = 47-99%), and specificity of 98% (95% CI = 86-100%). CONCLUSION: The FAM-CAM is a sensitive screening tool for detection of delirium in elderly adults with cognitive impairment using family caregivers, with relevance for research and clinical practice.

Sundown syndrome: a systematic review of the literature.

The label sundown syndrome continues to be frequently used in long-term and acute care settings without consistent meaning. This study adds to the understanding of this label by synthesizing findings from research published since 1987 linked to sundown syndrome. The purpose of this systematic review is to describe, synthesize, and critique the theoretical definitions, operational definitions and measurement methods, prevalence, antecedent and precipitating factors and consequences, and effectiveness of interventions for sundown syndrome found in the published literature. Implications for research and practice are presented.

Delirium: a very common problem you may not recognize.

Older adults with multiple pre-existing conditions are admitted to hospitals with acute illnesses and injuries every day. Delirium is not recognized by clinicians across health care settings. With awareness of risk factors and knowledge of delirium, nurses can play a pivotal role in the early identification, treatment, and, most important, prevention of delirium in older adults. Nurses often display a lack of knowledge related to delirium and the complex symptoms that appear differently in the presence of other complicating co-morbid conditions in aging adults. Nurses play a crucial role in keeping patients safe and ensuring optimal outcomes, regardless of the setting. With the growing population of older adults and the expected increases in chronic illness and dementia, delirium is a problem nurses are likely to experience in all practice settings. Knowing what to look for facilitates recognizing the risk and acting early to minimize (or even prevent) delirium.

Delirium superimposed on dementia: accuracy of nurse documentation.

Delirium is an acute, fluctuating confusional state that results in poor outcomes for older adults. Dementia causes a more convoluted course when coexisting with delirium. This study examined 128 days of documentation to describe what nurses document when caring for patients with dementia who experience delirium. Nurses did not document that they recognized delirium. Common descriptive terms included words and phrases indicating fluctuating mental status, lethargy, confusion, negative behavior, delusions, and restlessness. Delirium is a medical emergency. Nurses are in need of education coupled with clinical and decisional support to facilitate recognition and treatment of underlying causes of delirium in individuals with dementia.

Computerized decision support for delirium superimposed on dementia in older adults.

Delirium is common, deadly, and costly in people with dementia. The purpose of this pilot study was to test the feasibility of the computerized decision support component of an intervention strategy-Early Nurse Detection of Delirium Superimposed on Dementia-designed to improve nurse assessment and detection of delirium superimposed on dementia. This pilot study enrolled and followed 15 individuals with dementia (mean age = 83, mean admission Mini-Mental State Examination score = 14.8) and their caregivers daily for the duration of their hospitalization. Results indicated 100% adherence by nursing staff on the delirium assessment decision support screens and 75% adherence on the management screens. Despite the prevalence and severity of delirium in people with dementia, there are currently no published reports of the use of the electronic medical record in delirium detection and management. Success of this effort may encourage similar use of information technology in other settings.

Principle-based concept analysis: recognition in the context of nurse-patient interactions.

AIM: This paper is a report of a principle-based concept analysis of recognition in the context of nurse-patient interactions. BACKGROUND: Recognition is a concept employed in practice and research. Since nursing is patient-centred and care is problem-driven, the specificity and accuracy of recognition may have an impact on how nurses label patient phenomena, interventions initiated and patient outcomes. DATA SOURCES: The data set included 98 English language articles published from 1997 to 2008 and retrieved through Medline and CINAHL searches. METHODS: Principle-based concept analysis was used to examine the state of the science according to major perspectives of the philosophy of science. Conceptual components were integrated into a theoretical definition and the process of recognition was conceptually modelled. FINDINGS: The scientific literature dealing with recognition in the context of nurse-patient interactions relies on implied meaning. Recognition is a process marked by an awareness of evidence coupled with the formulation of a conceptual label summarizing the identified pattern of patient phenomena. Contextual features of the nurse, patient and organization are relevant during nurse-patient interactions, resulting in pivotal points in nursing care. These pivotal points are the moments of recognition when the nurse consciously applies a summary label to interpreted evidence. Outcomes of recognition include a choice to act or not to act, each option carrying significant outcomes for nurses, patients, and at times, organizations. CONCLUSION: A working definition was produced that will serve as a foundation for future concept-driven research to advance the concept toward greater precision and usefulness in nursing science.

A review of translations and adaptations of the Mini-Mental State Examination in languages other than English and Spanish.

This article provides a systematic review of linguistically and culturally adapted versions (translations) of the Mini-Mental State Examination (MMSE) in languages other than English and Spanish. Adapted versions were found via database search (PubMed, CINAHL, PsycINFO, and Linguistics and Language Behavior Abstracts). Source information (where available) is provided for each instrument. To facilitate comparison of the instruments, we developed an assessment framework that provides an organizational structure for the assessment of the quality of translation (linguistic and cultural), psychometric properties, educational considerations, and quality of field testing. The search resulted in 20 articles reporting on 15 language versions of the MMSE.

Are nurses recognizing delirium? A systematic review.

Delirium is a prevalent, costly, and global problem in older adults. This article is a systematic review of the literature on nurse recognition of delirium. Ten articles, reporting rates of nurse recognition ranging from 26% to 83%, were included in the review. The most compelling finding is that although related, the notions of nurse knowledge of delirium, nurse recognition of delirium, and nurses' assessment and documentation of delirium in older adults are different. Recommendations for practice are suggested at several levels, including education, guidelines, communication, health care system, and use of informatics.
