Use of Goal Attainment Scaling to Measure Treatment Effects in an Anti-Dementia Drug Trial

We report data on the validity and responsiveness (i.e. sensitivity to change) of assessment instruments including Goal Attainment Scaling (GAS), at a single site in a multicentre trial of the experimental therapeutic agent linopirdine. Fifteen people (11 women) were evaluated. GAS yielded a mean 3.7 goals per patient (range 2-6). The mean gain in the GAS scores, 2.7 +/- 16.4, was compared to changes in the Alzheimers Disease Assessment Scale-Cognitive Section, the Global Deterioration Scale, Clinical Global Impression and the Mini-Mental State Exam. GAS had the largest relative efficiency (0.47) when compared to the standard. GAS also had the largest effect size (0.61). The data suggest that an individualized approach may have merit as an outcome measure and as a means to better understanding treatment effects. Qualitative analysis revealed consistent goal setting in self-care, behaviour, cognition and leisure, suggesting that these areas should routinely be evaluated.

Palliative and therapeutic harmonization: a model for appropriate decision-making in frail older adults.

Frail older adults face increasingly complex decisions regarding medical care. The Palliative and Therapeutic Harmonization (PATH) model provides a structured approach that places frailty at the forefront of medical and surgical decision‐making in older adults. Preliminary data from the first 150 individuals completing the PATH program shows that the population served is frail (mean Clinical Frailty Score = 6.3), has multiple comorbidities (mean 8), and takes many medications (mean = 9). Ninety‐two percent of participants were able to complete decision‐making for an average of three current or projected health issues, most often (76.7%) with the help of a substitute decision‐maker (SDM). Decisions to proceed with scheduled medical or surgical interventions correlated with baseline frailty level and dementia stage, with participants with a greater degree of frailty (odds ratio (OR) = 3.41, 95% confidence interval (CI) = 1.39–8.38) or more‐advanced stage of dementia (OR = 1.66, 95% CI = 1.06–2.65) being more likely to choose less‐aggressive treatment options. Although the PATH model is in the development stage, further evaluation is ongoing, including a qualitative analysis of the SDM experience of PATH and an assessment of the effectiveness of PATH in long‐term care. The results of these studies will inform the design of a larger randomized controlled trial.

Evidence-Informed Guidelines for Treating Frail Older Adults With Type 2 Diabetes: From the Diabetes Care Program of Nova Scotia (DCPNS) and the Palliative and Therapeutic Harmonization (PATH) Program

Clinical practice guidelines specific to the medical care of frail older adults have yet to be widely disseminated. Because of the complex conditions associated with frailty, guidelines for frail older patients should be based on careful consideration of the characteristics of this population, balanced against the benefits and harms associated with treatment. In response to this need, the Diabetes Care Program of Nova Scotia (DCPNS) collaborated with the Palliative and Therapeutic Harmonization (PATH) program to develop and disseminate guidelines for the treatment of frail older adults with type 2 diabetes. The DCPNS/PATH guidelines are unique in that they recommend the following: 1. Maintain HbA1c at or above 8% rather than below a specific level, in keeping with the conclusion that lower HbA1c levels are associated with increased hypoglycemic events without accruing meaningful benefit for frail older adults with type 2 diabetes. The guideline supports a wide range of acceptable HbA1c targets so that treatment decisions can focus on whether to aim for HbA1c levels between 8% and 9% or within a higher range (ie, >9% and <12%) based on individual circumstances and symptoms. 2. Simplify treatment by administering basal insulin alone and avoiding administration of regular and rapid-acting insulin when feasible. This recommendation takes into account the variations in oral intake that are commonly associated with frailty. 3. Use neutral protamine Hagedorn (NPH) insulin instead of long-acting insulin analogues, such as insulin glargine (Lantus) or insulin detemir (Levemir), as insulin analogues do not appear to provide clinically meaningful benefit but are significantly more costly. 4. With acceptance of more liberalized blood glucose targets, there is no need for routine blood glucose testing when oral hypoglycemic medications or well-established doses of basal insulin (used alone) are not routinely changed as a result of blood glucose testing.Although these recommendations may appear radical, they are based on careful review of research findings.

The Feasibility of performing resistance exercise with acutely ill hospitalized older adults

BackgroundFor older adults, hospitalization frequently results in deterioration of mobility and function. Nevertheless, there are little data about how older adults exercise in the hospital and definitive studies are not yet available to determine what type of physical activity will prevent hospital related decline. Strengthening exercise may prevent deconditioning and Pilates exercise, which focuses on proper body mechanics and posture, may promote safety.MethodsA hospital-based resistance exercise program, which incorporates principles of resistance training and Pilates exercise, was developed and administered to intervention subjects to determine whether acutely-ill older patients can perform resistance exercise while in the hospital. Exercises were designed to be reproducible and easily performed in bed. The primary outcome measures were adherence and participation.ResultsThirty-nine ill patients, recently admitted to an acute care hospital, who were over age 70 [mean age of 82.0 (SD= 7.3)] and ambulatory prior to admission, were randomized to the resistance exercise group (19) or passive range of motion (ROM) group (20). For the resistance exercise group, participation was 71% (p = 0.004) and adherence was 63% (p = 0.020). Participation and adherence for ROM exercises was 96% and 95%, respectively.ConclusionUsing a standardized and simple exercise regimen, selected, ill, older adults in the hospital are able to comply with resistance exercise. Further studies are needed to determine if resistance exercise can prevent or treat hospital-related deterioration in mobility and function.

Retrospective Diagnosis of Dementia Using an Informant Interview Based on the Brief Cognitive Rating Scale

The accuracy of a dementia diagnosis by specialist physicians, as verified at an autopsy, is greater than 90% in many series. Donations of brains to the Maritime Brain Tissue Bank (MBTB) by individuals who did not have expert dementia diagnoses before death led us to investigate whether clinical features could also be detected retrospectively. Informants for 36 individuals whose brains were in the MBTB (18 women, mean age = 79 years; pathologic diagnoses: 75% Alzheimers disease [AD]; 8.4% vascular or mixed dementia) were interviewed by specialist physicians using a semistructured retrospective interview based on the Brief Cognitive Rating Scale (BCRS) (range = 1 [no impairment] to 7 [terminal dementia]). The mean duration of dementia was 8.5 +/- 12.8 years based on proxy reports, and most cases suggested severe dementia--(stage 6 [severe] or 7 [terminal])--on the retrospective BCRS (RetroBCRS) before death. A score of 4 or more on the RetroBCRS had 100% sensitivity and specificity in detecting dementia. The RetroBCRS score correlated moderately with duration (.51). In linear and logistic regression models adjusted for age and sex, RetroBCRS staging helped explain 93% of the variation in duration. The accuracy of the retrospective diagnosis of the cause of dementia, compared with autopsy, was 92%. The RetroBCRS used by an expert physician with a reliable informant is a valid method of detecting dementia and determining whether AD was present.

Behavioral problems in nursing home residents. Safe ways to manage dementia.

Preview Thanks to advances in health awareness and medical care, the elderly population continues to grow. But with added years of life comes an increase in age-related cognitive impairment and resulting behavioral problems (eg, agitation, wandering) that must be addressed by institutions and physicians. The authors describe patient evaluation and summarize approaches for initial and continuing treatment of behavioral problems related to dementia.

Evaluating the Implementation and Feasibility of a Web-Based Tool to Support Timely Identification and Care for the Frail Population in Primary Healthcare Settings

Background: Understanding and addressing the needs of frail persons is an emerging health priority for Nova Scotia and internationally. Primary healthcare (PHC) providers regularly encounter frail persons in their daily clinical work. However, routine identification and measurement of frailty is not standard practice and, in general, there is a lack of awareness about how to identify and respond to frailty. A web-based tool called the Frailty Portal was developed to aid in identifying, screening, and providing care for frail patients in PHC settings. In this study, we will assess the implementation feasibility and impact of the Frailty Portal to: (1) support increased awareness of frailty among providers and patients, (2) identify the degree of frailty within individual patients, and (3) develop and deliver actions to respond to frailtyl in community PHC practice. Methods: This study will be approached using a convergent mixed method design where quantitative and qualitative data are collected concurrently, in this case, over a 9-month period, analyzed separately, and then merged to summarize, interpret and produce a more comprehensive understanding of the initiative’s feasibility and scalability. Methods will be informed by the ‘Implementing the Frailty Portal in Community Primary Care Practice’ logic model and questions will be guided by domains and constructs from an implementation science framework, the Consolidated Framework for Implementation Research (CFIR). Discussion: The ‘Frailty Portal’ aims to improve access to, and coordination of, primary care services for persons experiencing frailty. It also aims to increase primary care providers’ ability to care for patients in the context of their frailty. Our goal is to help optimize care in the community by helping community providers gain the knowledge they may lack about frailty both in general and in their practice, support improved identification of frailty with the use of screening tools, offer evidence based severity-specific care goals and connect providers with local available community supports.

End of Life Care in Frailty

The increasing prevalence of frailty within the aging population poses challenges to current models of chronic disease management and end-of-life care delivery. As frailty progresses, individuals face an increasing frequency of acute health issues requiring medical attention. The ability of health care systems to recognize and respond to acute health issues in frail patients using a holistic understanding of health and prognosis will play a central role in ensuring their effective and appropriate care, including that at the end of their lives. This chapter reviews the history of palliative care and the elements of frailty that require the modification of current models of palliative care. In addition, tools and models for recognition of end of life in frailty and considerations for symptom management are introduced.

Proceedings of the Canadian Frailty Network Summit: Medication Optimization for Frail Older Canadians, Toronto, Monday April 24, 2017

Appropriate and optimal use of medication and polypharmacy are especially relevant to the care of older Canadians living with frailty, often impacting their health outcomes and quality of life. A majority (two thirds) of older adults (65 or older) are prescribed five or more drug classes and over one-quarter are prescribed 10 or more drugs. The risk of adverse drug-induced events is even greater for those aged 85 or older where 40% are estimated to take drugs from 10 or more drug classes. The Canadian Frailty Network (CFN), a pan-Canadian non-for-profit organization funded by the Government of Canada through the Networks of Centres of Excellence Program (NCE), is dedicated to improving the care of older Canadian living with frailty and, as part of its mandate, convened a meeting of stakeholders from across Canada to seek their perspectives on appropriate medication prescription. The CFN Medication Optimization Summit identified priorities to help inform the design of future research and knowledge mobilization efforts to facilitate optimal medication prescribing in older adults living with frailty. The priorities were developed and selected through a modified Delphi process commencing before and concluding during the summit. Herein we describe the overall approach/process to the summit, a summary of all the presentations and discussions, and the top ten priorities selected by the participants.

Palliative and therapeutic harmonization.

In the 1960s, Dame Cicely Saunders—a nurse who later trained to be a physician—became concerned that many individuals with advanced cancer and at the end of life were (1) not aware that their condition was terminal, (2) not given adequate pain control, and (3) treated with interventions that aimed to achieve cure, even when it was obvious that death was inevitable. Dame Saunders01 questioning of the status quo led to a dramatic change in the way we provide care and formed the foundation of palliative and hospice services. Although practices in the prepalliative era seem incomprehensible by today0s standards, the way we currently care for frail older adults echoes some of these prepalliative conventions. The term frailty characterizes older adults with complex medical illnesses or dementia and is associated with vulnerability to unfavourable outcomes, including an increased risk for adverse effects from medical treatments and shortened life expectancy. But, we do not commonly tell patients or their families about the vulnerability or shortened life expectancy associated with frailty. Likewise, as was true in the prepalliative era, we currently do a poor job of controlling symptoms at the end of life when frailty or dementia is present. However, the situation today is even more complicated. The specialization of modern healthcare, which focuses on addressing one illness at a time, contributes to system disorganization and may negatively affect the well-being of frail older adults. Physicians and other health professionals tend to chop frailty into its composite parts: the surgeon recommends repair of the abdominal aortic aneurysm; the social worker sees the social situation; the occupational therapist looks at function; and the dietician deals with weight loss—all without integrating their
