Decision tree for ward admissions of older patients at the emergency department after a fall.

AIM: Falls are a prevalent issue for the older population, and for the healthcare system in terms of emergency department (ED) access and hospitalizations. There is still a lack of knowledge and guidelines, however, regarding the need to hospitalize older patients accessing the ED after a fall. In the present study, we aimed to analyze the factors and the decisional process that led to older patients accessing the ED after a fall being admitted to hospital or discharged. METHODS: The study sample included 2144 older people who accessed the ED after a fall. For each patient, we obtained information on the nature of the fall and the related injuries, previous falls, dementia and ongoing medical therapies. As the outcome variable, we considered the indication for ward admission after the ED visit. RESULTS: Of the 2144 individuals who accessed the ED after a fall, 38% had at least one fracture, and 40.1% were admitted to a ward. The decision tree obtained using the chi-squared automatic interaction detection algorithm showed that the indication for ward admission could be accurately predicted (risk estimate 0.205) by just five factors, namely: presence and severity of fall-related injuries, reportedly suspicious fall dynamics, use of anticoagulants, polypharmacy, and dementia. CONCLUSIONS: The need for ward admission in older patients who access the ED after a fall seems to be determined not only by the severity of fall-related injuries, but also by the fall dynamics and the individual's clinical complexity.

Factors influencing short-term outcomes for older patients accessing emergency departments after a fall: The role of fall dynamics.

BACKGROUND: While the relevance of falls in raising the risk of fractures, hospitalization and disability in older age is well recognized, the factors influencing the onset of fractures and the need for ward admission after a fall have yet to be fully elucidated. We investigated which factors and fall dynamics were mainly associated with fall-related injuries and hospitalization among elderly persons accessing the Emergency Department (ED) following a fall. METHODS: The study involved 2144 older subjects who accessed the ED after a fall. Data on the fall´s nature and related injuries, ward admissions, history of falls, dementia, and medical therapies were examined for all patients. Considering dynamics, we distinguished accidental falls (due to interaction with environmental hazards while in motion) and falls from standing (secondary to syncope, lipothymia, drop attack, or vertigo). RESULTS: The overall prevalence of fractures in our population did not differ significantly with advancing age, though hip fractures were more common in the oldest, and upper limb fractures in the youngest patients. Falls from standing were associated with polypharmacy and with higher ward admission rate despite a lower fractures´ prevalence than accidental falls. The chances of fall-related fractures were more than fourfold as high for accidental dynamics (OR=4.05, 95%CI:3.10-5.29, p<0.0001). Ward admission was associated with polypharmacy, dementia, anticoagulants´ use and fall-related fractures (OR=6.84, 95%CI:5.45-8.58, p<0.0001), while it correlated inversely with accidental fall dynamics. CONCLUSIONS: Outcomes of falls in older age depend not only on any fall-related injuries, but also on factors such as polypharmacy, cognitive status and fall dynamics.

Heart Fat Infiltration In Subjects With and Without Coronary Artery Disease.

CONTEXT: Fat may accumulate around the heart in epicardial adipose tissue or inside the heart as lipid droplets (LDs). OBJECTIVE: To compare myocardial steatosis between subjects with and without coronary artery disease (CAD and non-CAD) and to identify which cells contain LDs. DESIGN: Body mass index, waist circumference, glucose, insulin, homeostasis model assessment index, leptin, adiponectin, and high-sensitivity C-reactive protein were evaluated in CAD and non-CAD subjects. Biopsies were collected from right atrial myocardium. Immunohistochemistry for perilipin (PLIN) 1 and 2 was used to characterize LDs and their localization in adipocytes or myocardial cells, respectively. Cardiomyocytes apoptosis and hypoxia inducible factor 1 alpha were obtained in a subgroup of subjects. SETTING: The study took place in a hospital. PATIENTS: Male subjects consecutively undergoing elective cardiac surgery either for coronary bypass grafting (CAD, n = 23) or for valve replacement (non-CAD, n = 18). MAIN OUTCOMES AND MEASURES: The study was designed to compare myocardial steatosis between subjects with and without coronary artery disease. RESULTS: PLIN1 and PLIN2 resulted significantly higher in CAD than in non-CAD subjects, as did apoptosis. PLIN1 was positively associated with circulating leptin, high-sensitivity C-reactive protein, and apoptosis, and negatively with adiponectin. PLIN2 was positively associated with body mass index, waist circumference, and leptin and negatively with adiponectin. After taking into account the absence/presence of hypertension, diabetes, and CAD/non-CAD, adiponectin was negatively associated with PLIN1 (r(2) = 0.532); waist circumference and adiponectin were associated with PLIN2 (r(2) = 0.399). CONCLUSIONS: Myocardial steatosis is greater in CAD than non-CAD subjects, depending on both metabolically active adipocytes interspersed among cardiomyocytes and higher fat deposition inside cardiomyocytes; serum adiponectin and waist circumference are independent predictors of myocardial steatosis.
