Association between low eosinophil count and acute bacterial infection, a prospective study in hospitalized older adults.

BACKGROUND: The incidence of sepsis increases significantly with age, including a high incidence of bacterial infection in the old adults. Eosinopenia and the CIBLE score have been proposed in critically ill adults and in internal medicine wards. This study aimed to assess whether a low eosinophil count was associated with acute bacterial infection among hospitalized older adults, and to find the most efficient eosinophil count cut-off to differentiate acute bacterial infection from other inflammatory states. METHODS: This was a prospective study from July 2020 to July 2022 in geriatric wards of the University Paul Brousse Hospital (Villejuif, France) including patients aged of 75 y/o or over suffering from fever or biological inflammation. Acute bacterial infection was assessed using biological identification and/or clinical and radiological data. RESULTS: A total of 156 patients were included. Eighty-two (53%) patients suffered from acute bacterial infection (mean age (SD) 88.7 (5.9)). Low eosinophil count was independently associated with acute bacterial infection: OR [CI95%] 3.03 [1.04-9.37] and 6.08 [2.42-16.5] for eosinophil count 0-0.07 G/L and 0.07-0.172 G/L respectively (vs. eosinophil count > 0.172 G/L). Specificity and sensitivity for eosinophil count < 0.01 G/L and CIBLE score were 84%-49% and 72%-62%, respectively with equivalent AUCs (0.66 and 0.67). CONCLUSION: Eosinophil count < 0.01 G/L is a simple, routinely used and inexpensive tool which can easily participate in antibiotic decisions for older adults. Further studies are needed to assess clinical benefits. TRIAL REGISTRATION: The study was registered at Clinical trial.gov (NCT04363138-23/04/2020).

[Psychiatric features in the elderly with or without dementia in a geriatric hospital]. / Typologie psychiatrique de la personne âgée avec ou sans démence dans un hôpital de gériatrie.

OBJECTIVES: The growing number of elderly people is challenging the reorganization of European health care systems. In France, there is an overlap between geriatric and psychiatric care of the elderly. This study was designed to describe the features of these patients, managed in both geriatric and geriatric psychiatry inpatient units. METHODS: We used The Programme Médicalisé de Système d'Information for the period 2009-2014. We focused on psychiatric disorders and dementia. RESULTS: 11.17% and 25% of patients have psychiatric disorders without dementia in geriatric and geriatric psychiatry units, respectively. Depression is the main mental illness. Their characteristics do not differ from those observed in other patients, apart from age. CONCLUSION: A part of the elderly psychiatric population is managed in the geriatric care system. Our results underline the importance of more integrated care between geriatric and psychiatry to prevent exclusion of patients from the health care system. Depression in elderly without dementia could justify the creation of specific inpatient units.

Hospital Discharge Decisions Concerning Older Patients: Understanding the Underlying Process.

ABSTRACTWe aimed to understand clinical decision-making processes that influence the orientation of older patients after hospital discharge. We compared discharge decisions (i.e., discharge home, or nursing home stay) of the hospital team with those of an expert panel. Both panel and hospital team made their decisions independently. The blind study included 102 patients (mean age: 83.13 ± 6.74). There is a statistically significant difference between expert and hospital team decisions (p < .001; kappa coefficient: 0.468). Panel decisions were more closely associated with isolation (p = .018), reliable caregivers (p = .004), social problems (p = .001), and behavioural symptoms perceived as aggressive (p = .001). Both decision processes considered refusal of care (p = 0,025 and 0.016 respectively) and social problems (p = .001 and < 0.001 respectively). Discharge planning models differ depending on the country, team and patient's condition. Our study suggests more precise evaluation of patients' needs.

The decision-making capacity of elderly hospitalized patients: validation of a test on their choice of return home.

Elderly hospitalized patients have uncertain or questionable capacity to make decisions about their care. Determining whether an elderly patient possesses decision-making capacity to return at home is a major concern for geriatricians in everyday practice. To construct and internally validate a new tool, the dream of home test (DROM-test), as support for decision making hospitalization discharge destination for the elderly in the acute or sub-acute care setting. The DROM-test consists of 10 questions and 4 vignettes based upon the 4 relevant criteria for decision-making: capacity to understand information, to appreciate and reason about medical risks and to communicate a choice. A prospective observational study was conducted during 6 months in 2 geriatric care units in Bretonneau Hospital (Assistance publique, Hôpitaux de Paris). We compared the patient decision of DROM-test regarding discharge recommendations with those of an Expert committee and of the team in charge of the patient. 102 were included: mean age 83.1 + 6.7 [70; 97], 66.67% females. Principal components analysis revealed four dimensions: choice, understanding, reasoning and understanding. The area under the ROC curve was 0.64 for the choice dimension, 0.59 for the understanding, 0.53 for the reasoning and 0.52 for the apprehension. Only the choice dimension was statistically associated with the decision of the committee of experts (p=0.017). Even though Drom-test has limitations, it provides an objective way to ascertain decision-making capacity for hospitalised elderly patients.
