Population Health Solutions for Assessing Cognitive Impairment in Geriatric Patients.

In December 2017, the National Academy of Neuropsychology convened an interorganizational Summit on Population Health Solutions for Assessing Cognitive Impairment in Geriatric Patients in Denver, Colorado. The Summit brought together representatives of a broad range of stakeholders invested in the care of older adults to focus on the topic of cognitive health and aging. Summit participants specifically examined questions of who should be screened for cognitive impairment and how they should be screened in medical settings. This is important in the context of an acute illness given that the presence of cognitive impairment can have significant implications for care and for the management of concomitant diseases as well as pose a major risk factor for dementia. Participants arrived at general principles to guide future screening approaches in medical populations and identified knowledge gaps to direct future research. Key learning points of the summit included: recognizing the importance of educating patients and healthcare providers about the value of assessing current and baseline cognition;emphasizing that any screening tool must be appropriately normalized and validated in the population in which it is used to obtain accurate information, including considerations of language, cultural factors, and education; andrecognizing the great potential, with appropriate caveats, of electronic health records to augment cognitive screening and tracking of changes in cognitive health over time.

Takotsubo cardiomyopathy and electroconvulsive treatments: a case study and review.

A 90-year-old woman who had received more than 100 electroconvulsive treatments (ECT) over many years requested another course for depression. After the third ECT, an electrocardiogram showed new T-wave inversion (V2-V6) and ST elevation (V2). Catheterization revealed severe left ventricular dysfunction but no coronary obstruction, leading to a diagnosis of Takotsubo cardiomyopathy (stress-related). The patient's recovery was uneventful. Recent literature cites three other cases post-ECT. It appears that elderly women are at greatest risk, repeated stress is generally required, and recovery is achieved quickly. Elevated levels of catecholamines and of vasopressin may be implicated.

The effect of a social work intervention to enhance advance care planning documentation in the nursing home.

OBJECTIVES: To assess the effect of a multicomponent advance care planning intervention directed at nursing home social workers on identification and documentation of preferences for medical treatments and on patient outcomes. DESIGN: Controlled clinical trial. SETTING: New York City nursing home. PARTICIPANTS: One hundred thirty-nine newly admitted long-term care residents. INTERVENTION: Nursing home social workers were randomized to the intervention or control groups. The intervention consisted of baseline education in advance care planning that incorporated small-group workshops and role play/practice sessions for intervention social workers; structured advance care planning discussions with residents and their proxies at admission, after any change in clinical status, and at yearly intervals; formal structured review of residents' goals of care at preexisting regular team meetings; "flagging" of advance directives on nursing home charts; and feedback to individual healthcare providers of the congruence of care they provided and the preferences specified in the advance care planning process. Control social workers received an educational training session on New York State law regarding advance directives but no additional training or interventions. Subjects were enrolled from January 9, 2001 through May 25, 2003 and followed for 6 months after enrollment. MEASUREMENTS: Nursing home chart documentation of advance directives (healthcare proxies, living wills) and do-not-resuscitate orders; preferences for artificial nutrition and hydration, intravenous antibiotics, and hospitalization; and concordance of treatments received with documented preferences were compared for residents assigned to intervention and control social workers. RESULTS: Intervention residents were significantly more likely than residents in the control group to have their preferences regarding cardiopulmonary resuscitation (40% vs 20%, P=.005), artificial nutrition and hydration (47% vs 9%, P<.01), intravenous antibiotics (44% vs 9%, P<.01), and hospitalization (49% vs 16%, P<.01) documented in the nursing home chart. Control residents were significantly more likely than intervention residents to receive treatments discordant with their prior stated wishes. Two of 49 (5%) intervention residents received a treatment in conflict with their prior stated wishes (one hospitalization, one episode of intravenous antibiotics), compared with 17 of 96 (18%) control patients (P=.04). CONCLUSION: This generalizable intervention directed at nursing home social workers significantly improved the documentation and identification of patients' wishes regarding common life-sustaining treatments and resulted in a higher concordance between patients' prior stated wishes and treatments received.

Screening for depression in nursing home palliative care patients.

The purpose of the this study was to evaluate the existing tools for assessing depression in nursing home patients referred to palliative care services. The patients referred to palliative care were assessed for depression by a geriatric fellow and a psychiatrist (gold standard). The questions asked by the fellow were derived from the existing validated screening scales and diagnostic tools. The psychiatrist's assessment had a strong agreement with the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV; kappa = 0.400) and Geriatric Depression Scale (GDS; kappa = 0.462) and least agreement with the Cornell Scale for Depression in Dementia (CDS). However, depression in the most severe dementia patients (Mini-Mental State Examination = 0) was able to be assessed only by the CDS. Thus, although items from the DSM-IV and GDS may be used to ascertain depression in geriatric patients, to date there is no scale valid and reliable enough to effectively ascertain depression in the most severely demented patients.

Cognitive burden and excess Lewy-body pathology in the Lewy-body variant of Alzheimer disease.

OBJECTIVES: Authors compared the degrees of cognitive deficit among individuals with Alzheimer disease (AD), the Lewy-body variant of AD (LBV), and "pure" dementia with Lewy bodies (DLB); and compared cortical Lewy body (LB) counts in LBV versus DLB and neuritic plaque and neurofibrillary tangle severity in LBV versus AD. METHODS: Authors examined brain specimens from consecutive autopsies of elderly nursing home subjects. Numbers and densities of plaques, Lewy bodies, and tangle severity were determined in multiple cortical regions, and demographic and clinical variables were compared among the three groups. RESULTS: The three groups did not differ in demographic or clinical variables. The LBV group was significantly more impaired than the other groups. Cortical LB counts were significantly higher in LBV than in DLB. There was no evidence of increased plaque or tangle severity in LBV than in AD. CONCLUSION: The co-occurrence of AD and LB pathology is associated with higher numbers of LBs and more severe dementia than when classical AD or LB lesions occur alone.

The prevalence, diagnosis and treatment of depression in dementia patients in chronic care facilities in the last six months of life.

OBJECTIVE: To assess the prevalence, diagnosis and treatment of depression among dementia patients and normal controls in chronic care facilities in the last six months of life. METHOD: We reviewed perimortal data concerning dementia severity, depressive symptoms and diagnoses, and medication use for 279 dementia patients and 24 normal controls brought to autopsy through an Alzheimer's Disease Resource Center. RESULTS: Major depression was highly prevalent among both dementia patients and normal controls in chronic care facilities in the last six months of life. This depression was under-diagnosed by physicians. Documentation of depressive symptoms by medical support staff has improved over time. However, physician diagnosis of depression has not improved. Recognition of depression was significantly lower for patients with severe dementia. Depression was under-treated in both dementia patients and normal controls, although treatment rates may be increasing. Anxiolytics and hypnotics were often used in lieu of, or in addition to, antidepressant therapy. CONCLUSIONS: Major depression was highly prevalent in both dementia patients and normal controls, indicating that depression is an important issue for the elderly in the last six months of life irrespective of cognitive status. Under-diagnosis of depression may be an important clinical issue. As physician diagnosis of depression has not improved with time, further physician training and/or awareness initiatives may be warranted. Depression, a treatable cause of excess morbidity and mortality, was undertreated in all groups studied. However, treatment rates may be improving. The prevalent use of anxiolytics and hypnotics for depressed patients is problematic.
