Iron deficiency and safety of ferric carboxymaltose in patients with acute heart failure. AHF-ID study.

INTRODUCTION: The presence of iron deficiency (ID) in patients with acute heart failure (AHF) is high. There are few studies on the characteristics of these patients and the safety of ferric carboxymaltose administration (FCM). OBJECTIVE: Study the differences among patients with AHF based on the presence and type of ID as well as the safety of FCM administration in these patients. METHOD: The AHF-ID study is a multicentre, analytical, prospective follow-up cohort including patients admitted to six Spanish hospitals for AHF. ID was defined as serum ferritin <100 µg/L (group A) or ferritin 100-299 µg/L with a TSAT <20% (group B). In cases receiving FCM the appearance of adverse events was analysed. Adjusted Cox regression was used to determine the association with 30-days reattendance for AHF after discharge. RESULTS: A total of 221 patients were recruited; 191 (86.4%) presented ID, 121 (63.4%) group A and 70 (36.6%) group B. There were scarce differences between the groups analysed. No differences were found in 30-days reattendance for AHF. FCM was administered to 158 (71.5%) patients, with 8 (5.1%) presenting adverse events, the most frequent being digestive alterations. Treatment was not discontinued in any case. CONCLUSIONS: There are scarce differences between the presence and the type of ID in patients with AHF. The administration of FCM in patients with ID and AHF is safe.

180-day risk of mortality in older patients admitted to short-stay units: the 6-Month Short-Stay Unit (6M UCE) Score. / Modelo de riesgo de mortalidad a 180 días en los pacientes ancianos ingresados en unidades de corta estancia: 6M UCE-SCORE.

OBJECTIVES: To develop a multidimensional score to assess risk of death for patients of advanced age 180 days after their admission to short-stay units (SSUs). MATERIAL AND METHODS: Prospective, multicenter, observational and analytical study of a cohort of patients aged 75 years or older who were admitted to 5 Spanish SSUs between February 1 and April 30, 2014. We recorded demographic and clinical data as well as geriatric assessment scores. A multilevel logistic regression model was developed to identify independent factors associated with 180-day mortality. The model was used to construct a scale for scoring risk. RESULTS: Data for 593 patients with a mean (SD) age of 83.4 (5.9) years entered the model; 359 (60.7%) were women. Ninety-two patients (15.5%) died within 180 days of SSU admission. Factors included in the final risk score were age over 85 years (1 point), male sex (1), loss of appetite or weight loss in the 3 months before admission (1), acute confusional state (2), functional dependence for basic activities of daily living at admission (2), and pressure ulcers (2). Low risk was indicated by a score of 0 to 2 points, intermediate risk by 3 to 5 points, and high risk by 6 to 9 points. Mortality rates at 180 days in these 3 risk groups were 5%, 18%, and 54%, respectively. The area under the receiver operating characteristic curve for the model after boots trapping was 0.72 (95% CI, 0.65-0.78). CONCLUSION: The SSU score could be useful for stratifying risk of death within 6 months of SSU admission of older patients, so that type of care can be tailored to risk.

OBJETIVO: Diseñar una escala de puntuación multidimensional con el fin de estratificar el riesgo de mortalidad a 180 días entre los ancianos ingresados en las unidades de corta estancia (UCE). METODO: Estudio analítico observacional de cohortes prospectivo multicéntrico que seleccionó todos los pacientes 75 años ingresados en 5 UCE españolas del 1 de febrero al 30 de abril de 2014. Se recogieron variables demográficas, clínicas y de la valoración geriátrica. Se derivó un modelo de regresión logística multinivel para identificar los factores independientemente asociados con la mortalidad a 180 días y después se construyó una escala de puntuación. RESULTADOS: Se incluyeron 593 pacientes (edad media 83,4 años, DE: 5,9; 359 mujeres, 60,7%), y 92 (15,5%) fallecieron a los 180 días. La escala de puntuación 6M UCE-SCORE incluyó la edad 85 años (1 punto), sexo varón (1 punto), presencia de pérdida de apetito o peso involuntaria en los últimos 3 meses (1 punto), síndrome confusional agudo (2 puntos), dependencia en las actividades básicas de la vida diaria al ingreso (2 puntos) y úlceras por presión (2 puntos). Se categorizó a los pacientes en bajo (0-2 puntos), intermedio (3-5 puntos) y alto (6-9 puntos) riesgo, con una mortalidad a 180 días de 5%, 18% y 54%, respectivamente. El ABC COR del modelo tras remuestreo fue de 0,72 (IC95%: 0,65-0,78). CONCLUSIONES: La escala de puntuación 6M UCE-SCORE podría ser de utilidad a la hora de estratificar el riesgo a 6 meses entre los ancianos ingresados en las UCE con el fin de diseñar un plan individualizado de cuidados.
