Dépression et niveau de fardeau chez les aidants familiaux des sujets déments en Tunisie

Introduction: La démence peut retentir lourdement sur les aidants familiaux du patient. Les objectifs de notre étude étaient de déterminer le niveau de fardeau et de la dépression chez les aidants familiaux de sujets déments, et d’identifier les facteurs associés à un niveau de fardeau élevé. Méthodes: Il s’agissait d’une enquête auprès de 65 aidants tunisiens. Les niveaux de fardeau et de la dépression ont été évalués par, respectivement, l’inventaire de Zarit et l’échelle de Beck. Résultats: Le taux des aidants qui avaient un niveau de fardeau élevé était de 52,3 %. Une dépression modérée ou sévère a été relevée chez 46,2 %. Un niveau de fardeau élevé était corrélé, du côté de l’aidant, avec le niveau socioéconomique moyen à élevé, la cohabitation avec le patient, le fait d’être son conjoint, la réduction des activités quotidiennes et la sévérité de la dépression, et, du côté du dément, avec l’agressivité. Conclusion: Les facteurs corrélés à un niveau de fardeau élevé orientent vers les cibles d’intervention et sont susceptibles d’être améliorés par la prise en charge, ce qui contribuerait à alléger la détresse des aidants

Cynicism and other attitudes towards patients in an emergency department in a middle eastern tertiary care center

Background: A caring, compassionate practitioner of the medical arts is the idealized version of what makes a good doctor. If asked to think of a painting of a doctor we most likely conjure an image of a physician sitting at a patient's bedside checking the pulse with a concerned look on his face. The reality is however that cynicism, among other negative attitudes, is becoming more prominent among physicians and medical staff. The causes and extent of cynicism likely vary among medical departments and different cultures. In this study, we aimed to assess attitudes of medical students and physicians in an Emergency Department (ED) in Lebanon that accommodates both local patients and is also known to attract patients from around the Middle East. Methods: A total of 30 students, residents and attending physicians at the American University of Beirut Medical Center were invited to participate. All participants underwent semi-structured interviews that were recorded, transcribed and then analyzed for common themes. Results: More negative emotions were expressed among participants than positive ones. Negative emotions were more frequently expressed among medical students, interns and residents than attending physicians. Cynicism in the ED was commonly reported however, maintenance of professionalism and adequate patient care were underscored. While empathy was recurrently found among participants, a trend towards a decrease in empathy with career progression was noted among attending physicians. Further, negative feelings towards patient families were prominent. Participants tended to categorize patients based on willingness to cooperate, gender, age, case acuity, ethnic origins and social status. Conclusions: Cynicism emerged as a prominent theme among medical students and staff in our study. However, participants were also empathetic. These attitudes were generally attributed to the peculiar stressors associated with the Lebanese culture, low acuity cases and "VIP" patients. It is crucial to explore methods in order to decrease cynicism and improve patient care. Also, the implications of these attitudes on patient care remain to be discovered.Nicholas J.

Human factors for dementia: Evidence based design

Designing care environments for people living with dementia is a complex challenge as the key stakeholder may have difficulty communicating their capabilities, limitations and preferences. This paper describes the use of evidence-based design personas in a multi-disciplinary team with architects and chartered human factors specialists. Four individual personas (Alison, Barry, Christine and David) and a couple persona (Chris and Sally) were used to bring the voices of the people living with different stages of dementia to the design process. Their changing/fluctuating symptoms were communicated in two formats (wheel and matrix) within an inclusive design process to adapt a Victorian semi-detached house. The demonstrator house presents evidence based design, adaptation and support solutions to support people living with dementia to age well at home

Validation of the 4AT tool for delirium assessment in specialist palliative care settings: protocol of a prospective diagnostic test accuracy study [version 1; peer review: 2 approved]

BACKGROUND: Delirium is a serious and distressing neuropsychiatric condition, which is prevalent across all palliative care settings. Hypoactive delirium is particularly common, but difficult to recognize, partly due to overlapping symptoms with depression and dementia. Delirium screening tools can lead to earlier identification and hence better management of patients. The 4AT (4 ‘A’s Test) is a brief tool for delirium detection, designed for use in clinical practice. It has been validated in 17 studies in over 3,700 patients. The test is currently used in specialist palliative care units, but has not been validated in this setting. The aim of the study is to determine the diagnostic accuracy of the 4AT for delirium detection against a reference standard, in hospice inpatients. METHODS: 240 participants will be recruited from the inpatient units of two hospices in Scotland. If a patient lacks capacity to consent, agreement will be sought from a legal proxy. Each participant will complete the 4AT and a reference standard assessment based on the diagnostic delirium criteria in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This will be supplemented by tests of cognition and attention, including reverse days of the week, counting down from 20 to 1, Vigilance 'A', the Observational Scale for Level of Arousal, the modified Richmond Agitation Sedation Scale and the Delirium Rating Scale-Revised-98. The assessments will be conducted in a randomized order by two independent clinicians, who will be blinded to the results until both are complete. Primary outcomes will be the sensitivity and specificity of the 4AT in detecting delirium. DISCUSSION: The findings will inform clinical practice regarding delirium assessment in palliative care settings. TRIAL REGISTRATION: ISRCTN ISRCTN97417474 (21/02/2020)

The Predictive Validity of the MoCA-LD for Assessing Mental Capacity in Adults with Intellectual Disabilities

Mental capacity assessments currently rely on subjective opinion. Researchers have yet to explore the association between key cognitive functions of rational decision-making and mental capacity classifications for people with intellectual disabilities. Sixty-three adults completed the Montreal Cognitive Assessment, which yielded estimates of their overall cognitive ability (MoCA-LD) as well as their memory, attention, language and executive functioning. Differences in scores were explored for those who had, and lacked, capacity and logistic regression was used to test the predictive validity of each measure. There were significant differences between both groups for all measures. Logistic regression identified MoCA-LD as a significant predictor of capacity assessment outcomes. ROC curve analysis provided novel, evidence-based benchmarks to help guide clinical practice based on individual MoCA-LD scores. This study offers a foundation for more objective approaches to mental capacity assessment. This demonstrates that assessments of cognitive ability can yield information that is helpful for mental capacity evaluations
