RESUMO
OBJECTIVES: A high incidence of delirium has been reported in older patients with Coronavirus disease 2019 (COVID-19). We aimed to identify determinants of delirium, including the Clinical Frailty Scale, in hospitalized older patients with COVID-19. Furthermore, we aimed to study the association of delirium independent of frailty with in-hospital outcomes in older COVID-19 patients. METHODS: This study was performed within the framework of the multi-center COVID-OLD cohort study and included patients aged ≥60 years who were admitted to the general ward because of COVID-19 in the Netherlands between February and May 2020. Data were collected on demographics, co-morbidity, disease severity, and geriatric parameters. Prevalence of delirium during hospital admission was recorded based on delirium screening using the Delirium Observation Screening Scale (DOSS) which was scored three times daily. A DOSS score ≥3 was followed by a delirium assessment by the ward physician In-hospital outcomes included length of stay, discharge destination, and mortality. RESULTS: A total of 412 patients were included (median age 76, 58% male). Delirium was present in 82 patients. In multivariable analysis, previous episode of delirium (Odds ratio [OR] 8.9 [95% CI 2.3-33.6] p = 0.001), and pre-existent memory problems (OR 7.6 [95% CI 3.1-22.5] p < 0.001) were associated with increased delirium risk. Clinical Frailty Scale was associated with increased delirium risk (OR 1.63 [95%CI 1.40-1.90] p < 0.001) in univariable analysis, but not in multivariable analysis. Patients who developed delirium had a shorter symptom duration and lower levels of C-reactive protein upon presentation, whereas vital parameters did not differ. Patients who developed a delirium had a longer hospital stay and were more often discharged to a nursing home. Delirium was associated with mortality (OR 2.84 [95% CI1.71-4.72] p < 0.001), but not in multivariable analyses. CONCLUSIONS: A previous delirium and pre-existent memory problems were associated with delirium risk in COVID-19. Delirium was not an independent predictor of mortality after adjustment for frailty.
RESUMO
OBJECTIVES: Transcatheter aortic valve implantation (TAVI) is an important treatment option for patients with severe aortic stenosis. To improve patient selection, shared decision-making is recommended to elicit patients' treatment expectations and goals. We assessed patients' expectations and goals before TAVI treatment and whether these were met after treatment. Additionally, we evaluated how meeting these goals aligned with quality of life and functional recovery. DESIGN: A mixed method study. SETTING: An academic medical center. PARTICIPANTS: Seventy-four patients undergoing TAVI between 2015 and 2017. MEASUREMENTS: Patients' expectations and goals were assessed qualitatively before treatment. Six to twelve months post procedure, quality of life was measured with the EuroQuol-5D and any change in the number of dependencies in (instrumental) activities of daily living was assessed. RESULTS: Mean age of patients was 81.5 years, and 37.8% were male. Regaining the ability to engage in a specific hobby or activity was the most important treatment goal (33 patients, 54.1%), followed by reducing symptoms (19 patients 31.1%). 66.2% of patients stated that their treatment goal was met. Quality of life was higher in this group, as compared with patients who had not met their treatment goal. Twenty-three patients (31.1%) showed functional improvement. CONCLUSION: TAVI patients were quite capable of eliciting treatment goals and a majority stated, after treatment, that these had been met patients' experience of treatment benefits regarding these goals had poor alignment with functional outcomes. This raises questions regarding relevant outcome measurements in this population, and could aid in improving shared decision-making and patient selection for TAVI.

OBJECTIVES: To assess the association between serum S100B levels (a marker of brain damage), delirium, and subsequent cognitive decline. DESIGN: Substudy of a multicenter randomized controlled trial. SETTING: Surgical, orthopedic, and trauma surgery wards of two teaching hospitals. PARTICIPANTS: Individuals aged 65 and older (range 65-102) admitted for hip fracture surgery (N = 385). MEASUREMENTS: During hospitalization, presence of delirium was assessed daily. S100B was assayed in repeated serum samples. Twelve months after discharge, cognitive decline and mortality were evaluated. Cognitive decline was defined as an increase in Informant Questionnaire on Cognitive Decline Short Form score of 1 standard deviation or more or a decrease in Mini Mental State Examination score of 3 points or more between admission and 12 months after discharge. RESULTS: Premorbid cognitive impairment was present in 226 (58.7%) participants, and 127 (33.0%) experienced perioperative delirium. Multivariable analysis showed that older age and presence of infection, but not of delirium, were associated with higher S100B levels. Levels were also higher after surgery than before. Of participants with perioperative delirium, 58.6% experienced cognitive decline or death, and only age was a risk factor; 36.5% of participants without perioperative delirium experienced cognitive decline or death in the following year, and higher S100B, premorbid cognitive impairment, and older age were risk factors. CONCLUSION: In a cohort of older adults with hip fracture, no association was found between serum S100B levels and occurrence of delirium. S100B was associated with cognitive decline or death in the first year after hip fracture only in participants without perioperative delirium. S100B seems to be of limited value as a biomarker of brain damage associated with delirium.

OBJECTIVES: Change in cognitive functioning is often observed after hip fracture. Different patterns, with both improvement and decline, are expected, depending on premorbid cognitive functioning and events that occur during hospitalization. These patterns are unknown and important for older hip fracture patients with different levels of premorbid cognitive functioning. DESIGN, SETTING, PARTICIPANTS, MEASUREMENTS: We conducted a secondary analysis of a multi-center randomized controlled trial. 302 consecutive patients aged 65-102 years old, admitted for hip fracture surgery, were enrolled. The Mini Mental State Examination (MMSE) was obtained at hospital admission, at discharge, and at 3 and 12 months after discharge. Cognitive trajectories were identified with Group Based Trajectory Modelling, using the repeated MMSE measurements as outcome variable. To illustrate the specific characteristics of this relative novel methodological approach, it was contrasted with results obtained from linear mixed effects modeling. RESULTS: 146 (48.3%) patients had premorbid cognitive impairment and 85 patients (28.1%) experienced delirium during admission. Three distinct cognitive trajectories were identified and labeled based on different MMSE course over time: improvement (57.9%), stable (28.1%), and rapid decline (13.9%), with an annual MMSE change of 1.7, 0.8, and -3.5 points respectively. With mixed effects modeling an overall annual increase of 0.7 MMSE points was estimated for the group as a whole. CONCLUSION: Three distinct cognitive trajectories were identified in a population of older hip fracture patients. These trajectory groups can be used as a starting point to inform patients and caregivers on the possible prognosis after hip fracture. Group based trajectory modelling is a useful technique when the purpose is to describe patterns of change within a population and a variety of trajectories are expected to exist.
