Use of healthcare resources and costs of acute cardioembolic stroke management in the Region of Madrid: The CODICE Study.

INTRODUCTION: Stroke is the main cause of admission to Neurology departments and cardioembolic stroke (CS) is one of the most common subtypes of stroke. METHODS: A multicentre prospective observational study was performed in 5 Neurology departments in public hospitals in the Region of Madrid (Spain). The objective was to estimate the use of healthcare resources and costs of acute CS management. Patients with acute CS at<48h from onset were recruited. Patients' socio-demographic, clinical, and healthcare resource use data were collected during hospitalisation and at discharge up to 30 days after admission, including data for rehabilitation treatment after discharge. RESULTS: During an 8-month recruitment period, 128 patients were recruited: mean age, 75.3±11.25; 46.9% women; mortality rate, 4.7%. All patients met the CS diagnostic criteria established by GEENCV-SEN, based on medical history or diagnostic tests. Fifty per cent of the patients had a history of atrial fibrillation and 18.8% presented other major cardioembolic sources. Non-valvular atrial fibrillation was the most frequent cause of CS (33.6%). Data for healthcare resource use, given a mean total hospital stay of 10.3±9.3 days, are as follows: rehabilitation therapy during hospital stay (46.9%, mean 4.5 days) and after discharge (56.3%, mean 26.8 days), complications (32%), specific interventions (19.5%), and laboratory and diagnostic tests (100%). Head CT (98.4%), duplex ultrasound of supra-aortic trunks (87.5%), and electrocardiogram (85.9%) were the most frequently performed diagnostic procedures. Average total cost per patient during acute-phase management and rehabilitation was €13,139. Hospital stay (45.0%) and rehabilitation at discharge (29.2%) accounted for the largest part of resources used. CONCLUSIONS: Acute CS management in the Region of Madrid resulted consumes large amounts of resources (€13,139), mainly due to hospital stays and rehabilitation.

[Acalculia: its classification, aetiology and clinical management]. / Acalculia: clasificación, etiología y tratamiento clínico.

AIM: To carry out a review of the literature on the different neurological mechanisms involved in processing calculations, the injuries to brain structure that can result in acalculia and the clinical management of these patients. Development and conclusions. Acalculia is defined as the disorder affecting the ability to calculate that is acquired as the result of a brain injury. Despite being a frequent symptom and its association to numerous systemic and neurological diseases, no clear study protocol exists due to the fact that, first, it is usually accompanied by other, more important neurological symptoms and, second, it occurs in a very heterogeneous population, where clear differences can be seen according to the sociocultural level of the patient. Acalculia has been associated both to general alterations of the central nervous system and to others affecting local structures. Perhaps the most striking example of the former is the case of dementias, where it has even been suggested that it could be an early sign of Alzheimer's disease. With respect to the latter, the most notable are those affecting the left parietal lobe. In this article the following are discussed: 1) the different classifications that have been developed for the loss of the ability to calculate; 2) the involvement of the different structures of the nervous system in numeric processing, based on the associated structural lesions and on studies that have been conducted using functional tests and brain imaging; and 3) the different neuropsychological instruments that are available to study this capacity.
