Charlson's comorbidity index, risk factor delirium

OBJECTIVES: Delirium is commonly seen in older adults with multimorbidity, during a hospitalization, resulting from the interplay between predisposing factors such as advanced age, frailty, and dementia, and a series of precipitating factors. The association between delirium and specific multimorbidity is largely unexplored so far although of potential key relevance for targeted interventions. The aim of the study was to check for a potential association of multimorbidity with delirium in a large cohort of older patients hospitalized for an acute medical or surgical condition...

OBJECTIVE: Postoperative delirium (POD) is a common postoperative complication that is relevant to poor outcomes. Therefore, it is critical to find effective methods to identify patients with high risk of POD rapidly. Creating a fully automated score based on an automated machine-learning algorithm may be a method to predict the incidence of POD quickly. MATERIALS AND METHODS: This is the secondary analysis of an observational study, including 531 surgical patients who underwent general anesthesia...

BACKGROUND: The aim of the present study was to investigate the outcome of patients with SARS-CoV-2 infection and dementia. PATIENTS AND METHODS: In a multicenter, observational, 1:2 matched case-control study all 23 patients with a history of dementia, hospitalized with a diagnosis of SARS-CoV-2 infection from February 28th 2020 to January 31st 2021 were enrolled. For each Case, 2 patients without dementia observed in the same period study, pair matched for gender, age (±5 years), PaO2 /FiO2 (P/F) ratio at admission (<200, or >200), number of comorbidities (±1; excluding dementia) were chosen (Control group)...

OBJECTIVE: To evaluate the incidence and risks factors of short-term post-intensive care (ICU) cognitive impairment. DESIGN: Prospective, observational study. SETTING: Closed university-affiliated intensive care unit. PATIENTS: We enrolled consecutive patients >18 yrs of age expected to be in intensive care unit for ≥24 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The score of Montreal Cognitive Assessment (MoCA) less than 26 was defined as cognitive impairment at hospital discharge and short-term post-ICU cognitive impairment was diagnosed in 185 of 409 assessed patients (45...

BACKGROUND: Acute medical illnesses, surgical interventions, or admissions to hospital in older individuals are frequently associated with a delirium. In this cohort study, we investigated the impact of specific cognitive domains and depression before the occurrence of delirium symptoms in an 8-year observation of older non-hospitalized individuals. METHODS: In total, we included 807 participants (48-83 years). Deficits in specific cognitive domains were measured using the CERAD test battery, and depressive symptoms were measured using Beck Depression Inventory and the Geriatric Depression Scale (GDS) before the onset of a delirium...

BACKGROUND: Early identification of older cardiac patients at high risk of readmission or mortality facilitates targeted deployment of preventive interventions. In the Netherlands, the frailty tool of the Dutch Safety Management System (DSMS-tool) consists of (the risk of) delirium, falling, functional impairment, and malnutrition and is currently used in all older hospitalised patients. However, its predictive performance in older cardiac patients is unknown. AIM: To estimate the performance of the DSMS-tool alone and combined with other predictors in predicting hospital readmission or mortality within 6 months in acutely hospitalised older cardiac patients...

BACKGROUND: Chemoradiotherapy for Esophageal cancer followed by Surgery (CROSS regimen) is standard of care for locally-advanced esophageal cancer. We evaluated CROSS completion rates, toxicity, and postoperative outcomes between older and younger adults receiving trimodality therapy. METHODS: Retrospective analysis of patients with locally-advanced esophageal cancer who underwent CROSS regimen from May 2016 to January 2020 at a single academic center. Outcomes of those aged ≥70-years-old and <70 years-old were analyzed...

OBJECTIVE: We aimed to identify socioeconomic and clinical risk factors for post-intensive care unit (ICU)-related long-term cognitive impairment (LTCI). SUMMARY BACKGROUND DATA: After delirium during ICU stay, LTCI has been increasingly recognized, but without attention to socioeconomic factors. METHODS: We enrolled a prospective, multicenter cohort of ICU survivors with shock or respiratory failure from surgical and medical ICUs across 5 civilian and Veteran Affairs (VA) hospitals from 2010 to 2016...

BACKGROUND: The influence of preoperative comprehensive geriatric assessment and frailty on postoperative morbidity, mortality, delirium were examined. METHODS: A total of 108 patients were evaluated. The Katz Index of Independence in Activities of Daily Living (ADL), the Lawton Brody Instrumental Activities of Daily Living Scale (IADL), the Mini-Nutrition Assessment test (MNA), the Mini-Mental State Examination (MMSE), Yesavage Geriatric Depression Scale (GDS) were performed...

BACKGROUND: The increase in life expectancy has led to the appearance of a subgroup of hip fracture (HF) patients with special characteristics known as centenarians. The aim of the present study is to analyse the demographic characteristics, complications and mortality rate of this subgroup in order to identify the specific risk factors for mortality in these patients. METHODS: Retrospective analysis of 69 patients (58 women and 11 men) aged 100 years or older admitted to a tertiary hospital for HF between 1999 and 2018...

BACKGROUND: Delirium is common in old patients who undergo cardiac surgery, and it is associated with adverse outcomes. The genesis of delirium is thought to be multi-factorial, but it is still not well understood. Symptoms of depression and elevated cortisol level have been described in some previous studies as factors associated with delirium, suggesting a shared pathophysiology. AIMS: The objective of the present study was to determine whether preoperative depression symptoms and increased cortisol level represent risk factors for delirium after cardiac surgery...

INTRODUCTION: Very few population-based assessments of delirium have been performed to date. These have not assessed the implications of delirium after major surgical oncology procedures (MSOPs). We examined the temporal trends of delirium following 10 MSOPs, as well as patient and hospital delirium risk factors. Finally, we examined the effect of delirium on length of stay, inhospital mortality, and hospital charges. METHODS: We retrospectively identified patients who underwent prostatectomy, colectomy, cystectomy, mastectomy, gastrectomy, hysterectomy, nephrectomy, oophorectomy, lung resection, or pancreatectomy within the Nationwide Inpatient Sample (2003-2013)...

OBJECTIVE: To investigate the occurrence and influencing factors of long-term cognitive impairment in patients with sepsis. METHODS: The septic patients admitted to intensive care unit (ICU) of Tianjin Third Central Hospital from July 2014 to September 2017 were enrolled. Montreal cognitive assessment scale (MoCA) was used to assess the cognitive function of patients at 3, 12 and 24 months after discharge from hospital. The patients were divided into cognitive impairment group (MoCA score < 26) and normal cognitive function group (MoCA score ≥ 26) according to the MoCA scores at 12 months after discharge from hospital...

The incidence of hip fractures is increasing due to demographic transition. Data on long-term survival and influencing factors are sparse. Our prospective observational study with 395 patients shows a survival of 38% after 5 years. Significant risk factors were male gender, higher age, lower Barthel Index, lower Charlson Comorbidity Score, lower Mini-Mental State Examination, and delirium during hospitalization. PURPOSE: The incidence of hip fractures is increasing due to demographic transition...

BACKGROUND: The Strategy to Reduce the Incidence of Postoperative Delirium in the Elderly trial tested the hypothesis that limiting sedation during spinal anaesthesia decreases in-hospital postoperative delirium after hip fracture repair. This manuscript reports the secondary outcomes of this trial, including mortality and function. METHODS: Two hundred patients (≥65 yr) undergoing hip fracture repair with spinal anaesthesia were randomised to heavier [modified Observer's Assessment of Alertness/Sedation score (OAA/S) 0-2] or lighter (OAA/S 3-5) sedation, and were assessed for postoperative delirium...

Objective: Hospitalization of patients with delirium after visiting the emergency department (ED) is often required. However, the readmission risk after discharge from the ED should also be considered. This study aimed to explore whether (i) immediate hospitalization influences the readmission risk of patients with delirium; (ii) the readmission risk is affected by various risk factors; and (iii) the healthcare cost differs between groups within 28 days of the first ED visit. Methods: Using the National Health Insurance Research Database, the data of 2,780 subjects presenting with delirium at an ED visit from 2000 to 2008 were examined...

IMPORTANCE: Postoperative delirium is the most common complication following major surgery in older patients. Intraoperative sedation levels are a possible modifiable risk factor for postoperative delirium. OBJECTIVE: To determine whether limiting sedation levels during spinal anesthesia reduces incident delirium overall. DESIGN, SETTING, AND PARTICIPANTS: This double-blind randomized clinical trial (A Strategy to Reduce the Incidence of Postoperative Delirum in Elderly Patients [STRIDE]) was conducted from November 18, 2011, to May 19, 2016, at a single academic medical center and included a consecutive sample of older patients (≥65 years) who were undergoing nonelective hip fracture repair with spinal anesthesia and propofol sedation...

BACKGROUND CONTEXT: The incidence of postoperative complications after microendoscopic laminectomy (MEL) has not been compared with that after open laminectomy in a large study, so it is not clear whether MEL is a safer procedure. PURPOSE: The objective of this study was to compare postoperative morbidity and mortality following lumbar laminectomy between patients treated with MEL and with open laminectomy. STUDY DESIGN: This is a retrospective cohort study with propensity score-matched analysis...

BACKGROUND: With the ageing of the general population, demand has grown for measures to prevent hospitalization for dementia, which can exacerbate problems associated with activities of daily living in elderly individuals. Anticholinergic medication has been shown to cause falls, delirium, and cognitive impairment in aged patients. However, the risk of hospitalization associated with the administration of anticholinergics is unclear. METHODS: We analyzed the records of 61 outpatients (26 men, 35 women; mean age: 78 ± 7 years; mean follow-up period: 420 days) diagnosed with dementia (Alzheimer's disease: n = 45; dementia with Lewy bodies: n = 3; undifferentiated n = 13) and prescribed anti-dementia drugs between May 2013 and December 2014...

BACKGROUND: Prescribing of medications with anticholinergic properties in older nursing home residents is relatively common, despite an association with an increased risk for falls, delirium, and other outcomes. Few studies have investigated what factors influence different levels of prescribing of these agents. OBJECTIVES: The primary objective was to identify factors associated with low- and high-level anticholinergic burden in nursing home residents. A secondary objective was to examine in detail the contribution of different medications to low versus high burden to aid in determining which drugs to target in interventions...
