Treatment variability and its relationships to outcomes among patients with Wernicke's encephalopathy: A multicenter retrospective study.

BACKGROUND: Despite guidelines and recommendations, Wernicke's encephalopathy (WE) treatment lacks evidence, leading to clinical practice variability. AIMS: Given the overall lack of information on thiamine use for WE treatment, we analyzed data from a large, well-characterized multicenter sample of patients with WE, examining thiamine dosages; factors associated with the use of different doses, frequencies, and routes; and the influence of differences in thiamine treatment on the outcome. METHODS: This retrospective study was conducted with data from 443 patients from 21 centers obtained from a nationwide registry of the Spanish Society of Internal Medicine (from 2000 to 2012). Discharge codes and Caine criteria were applied for WE diagnosis, and treatment-related (thiamine dosage, frequency, and route of administration) demographic, clinical, and outcome variables were analyzed. RESULTS: We found marked variability in WE treatment and a low rate of high-dose intravenous thiamine administration. Seventy-eight patients out of 373 (20.9%) received > 300mg/day of thiamine as initial dose. Patients fulfilling the Caine criteria or presenting with the classic WE triad more frequently received parenteral treatment. Delayed diagnosis (after 24h hospitalization), the fulfillment of more than two Caine criteria at diagnosis, mental status alterations, and folic acid deficiency were associated significantly with the lack of complete recovery. Malnutrition, reduced consciousness, folic acid deficiency, and the lack of timely thiamine treatment were risk factors for mortality. CONCLUSIONS: Our results clearly show extreme variability in thiamine dosages and routes used in the management of WE. Measures should be implemented to ensure adherence to current guidelines and to correct potential nutritional deficits in patients with alcohol use disorders or other risk factors for WE.

Alcoholic Liver Disease Among Patients with Wernicke Encephalopathy: A Multicenter Observational Study.

BACKGROUND: data regarding the association between Wernicke encephalopathy (WE) and alcoholic liver disease (ALD) are scarce in spite of alcohol consumption being the main risk factor for WE. AIMS: to describe the frequency of ALD in a cohort of patients diagnosed with WE and alcohol use disorders (AUDs) and to compare the characteristics of WE patients with and without ALD. METHODS: we conducted an observational study in 21 centers through a nationwide registry of the Spanish Society of Internal Medicine. WE Caine criteria were applied and demographic, clinical, and outcome variables were analyzed. RESULTS: 434 patients were included in the study, of which 372 were men (85.7%), and the mean age was 55 ± 11.8 years. ALD was present in 162 (37.3%) patients and we found a higher percentage of cases with tremor, flapping and hallucinations in the ALD group. A total of 22 patients (5.0%) died during admission (7.4% with ALD vs 3.7% without ALD; P = 0.087). Among the ALD patients, a relationship between mortality and the presence of anemia (Odds ratio [OR]=4.6 Confidence interval [CI]95% 1.1-18.8; P = 0.034), low level of consciousness (OR=4.9 CI95% 1.1-21.2; P = 0.031) and previous diagnosis of cancer (OR=10.3 CI95% 1.8-59.5; P = 0.009) was detected. Complete recovery was achieved by 27 patients with ALD (17.8%) and 71 (27.8%) without ALD (P = 0.030). CONCLUSION: the association of WE and ALD in patients with AUDs is frequent and potentially linked to differences in clinical presentation and to poorer prognosis, as compared to alcoholic patients with WE without ALD.

Tasas de incidencia de ingresos asociados a síndrome de abstinencia alcohólica en España: análisis del conjunto mínimo básico de datos 1999-2010 / Incidence rates of admissions associated with alcohol withdrawal syndrome in Spain: Analysis of minimum basic data set 1999-2010

Introducción: No existen datos acerca de la incidencia de ingresos asociados a síndrome de abstinencia alcohólica (SAA) ni sobre su evolución en los últimos años en España. Objetivos: Analizar las características, tasas de incidencia y tendencia evolutiva de los ingresos hospitalarios asociados a SAA en hospitales públicos españoles. Material y método: Análisis de la base de datos del CMBD de hospitales públicos españoles de los ingresos hospitalarios con SAA (CIE9-MC 291.81), delirio por abstinencia alcohólica (CIE9-MC 291.0) o alucinosis por abstinencia alcohólica (CIE9-MC 291.3), entre los años 1999 y 2010. Resultados: Se registraron 56.395 ingresos asociados a SAA. La edad media fue de 50,9 años (DE 12,5) y el 88% eran hombres. El servicio de ingreso más frecuente fue Medicina Interna (24,9%). La estancia media global fue de 12,6 días (DE 14,4) y la mortalidad del 4,7%. El 62,6% desarrollaron SAA durante un ingreso por otro motivo, en su mayoría por enfermedades relacionadas con el alcohol. Los diagnósticos secundarios en pacientes que ingresaron por SAA tenían relación directa o indirecta con el consumo de alcohol en más de la mitad de los casos. La tasa de incidencia de ingresos en España asociados a SAA se mantuvo estable entre 1999 y 2010, con un ligero descenso en los 3 últimos años del periodo. Las comunidades con mayor incidencia fueron Canarias, Baleares y Galicia. Conclusiones: La incidencia de ingresos asociados a SAA en hospitales públicos españoles se ha mantenido estable con pequeñas modificaciones en el periodo 1999-2010. Existen diferencias en la incidencia de ingresos asociados a SAA entre las diferentes comunidades autónomas

Background: There are no data on the incidence of admissions associated with alcohol withdrawal syndrome (AWS) or about its trend over time in Spain. Objective: To analyze the characteristics, incidence rates and trends over time of hospital admissions associated with AWS in Spanish public hospitals. Material and method: Analysis from the Spanish public hospitals minimum basic data set of hospital admissions with AWS (CIE9-MC 291.81), alcohol withdrawal delirium (CIE9-MC 291.0) and alcohol withdrawal hallucinosis (CIE9-MC 291.3), since 1999 to 2010. Results: We identified 56,395 admissions associated with AWS. Mean age was 50.9 (SD 12.5) and 88% were male. The most frequent admission department was Internal Medicine (24.9%). The mean hospital stay was 12.6 days (SD 14.4) and mortality was 4.7%; 62.6% of cases developed AWS during an admission for another reason, mostly due to alcohol-related pathologies. Secondary diagnoses in patients hospitalized for AWS were related to alcohol consumption in more than half of the cases. The incidence rate of admissions associated with AWS in Spain remained stable from 1999 to 2010, with a small decline in the last 3 years of the period. The communities with the highest incidence were the Canary Islands, the Balearic Islands and Galicia. Conclusions: The incidence rate of admissions associated with AWS in Spanish public hospitals in the period 1999-2010 has remained stable with slight changes. There are differences in the incidence of AWS among the different autonomous communities

Differences Between Alcoholic and Nonalcoholic Patients With Wernicke Encephalopathy: A Multicenter Observational Study.

OBJECTIVE: To analyze the differences in characteristics and prognosis between alcoholic and nonalcoholic patients with Wernicke encephalopathy (WE). PATIENTS AND METHODS: A retrospective observational cohort of 468 patients diagnosed with WE with at least 2 Caine criteria was selected from all patients discharged with a diagnosis of WE from 21 medical centers in Spain from January 1, 2000, through December 31, 2012. Demographic, clinical, and outcome variables were described. RESULTS: Among the 468 patients, the most common risk factor was alcoholism (n=434 [92.7%]). More than one-third of patients (n=181 [38.7%]) had the classic WE triad of symptoms (ocular signs, cerebellar dysfunction, and confusion). Among 252 patients for whom magnetic resonance imaging data were available, 135 (53.6%) had WE-related lesions and 42 (16.7%) had cerebellar lesions. Of the 468 patients, 25 (5.3%) died during hospitalization. Alcoholic patients presented more frequently than nonalcoholic patients with cerebellar signs (P=.01) but less frequently with ocular signs (P=.02). Alcoholic patients had a significantly higher frequency of hyponatremia (P=.04) and decreased platelet count (P=.005) compared with nonalcoholics. Alcoholic patients were diagnosed earlier than nonalcoholics (median time to diagnosis, 1 vs 4 days; P=.001) and had shorter hospitalizations (13 vs 23 days; P=.002). CONCLUSION: Compared with nonalcoholic patients, alcoholic patients with WE are more likely to present with cerebellar signs and less likely to have ocular signs. Diagnosis may be delayed in nonalcoholic patients. Mortality in the present series was lower than described previously.

Ferric carboxymaltose with or without erythropoietin in anemic patients with hip fracture: a randomized clinical trial.

BACKGROUND: The increasing incidence of osteoporotic hip fracture (HF) has raised the requirements of red blood cell (RBC) transfusions, whereas this scarce resource may cause morbidity and mortality. STUDY DESIGN AND METHODS: This study was a multicenter, randomized, double-blind, clinical trial that aimed to assess efficacy of ferric carboxymaltose (FCM) with or without erythropoietin (EPO) in reducing RBC transfusion in the perioperative period of HF. Participants (patients > 65 years admitted with HF and hemoglobin [Hb] levels of 90-120 g/L) were randomly assigned to receive a preoperative single dose of 1 g of FCM (short intravenous [IV] infusion over 15 min), plus 40,000 IU of subcutaneous EPO (EPOFE arm); versus 1 g of IV FCM plus subcutaneous placebo (FE arm); and versus IV and subcutaneous placebo (placebo arm). Primary endpoint was the percentage of patients who received RBC transfusion, and secondary endpoints were the number of RBC transfusions per patient, survival, hemoglobinemia, and health-related quality of life (HRQoL; by means of Short Form 36 Version 2 questionnaire). RESULTS: A total of 306 patients (85% women, mean age 83 ± 6.5 years) were included. A total of 52, 51.5, and 54% of patients required RBC transfusion in the EPOFE, FE, and placebo arms, respectively, with no significant differences in the number of RBC transfusions per patient, survival, HRQoL, and adverse events among treatment groups. A significant increase in Hb levels was achieved at discharge (102 g/L vs. 97 g/L) and 60 days after discharge (125 g/L vs. 119 g/L) in the EPOFE arm with respect to placebo arm; in addition, a higher rate of patients recovered from anemia in the EPOFE arm with respect to the placebo arm (52% vs. 39%), 60 days after discharge. CONCLUSION: Preoperative treatment with FCM alone or in combination with EPO improved recovery from postoperative anemia, but did not reduce the needs of RBC transfusion in patients with HF.

Characteristics and temporal pattern of the readmissions of patients with multiple hospital admissions in the medical departments of a general hospital.

INTRODUCTION: Patients with multiple hospital admissions represent a small percentage of total hospitalizations but result in a considerable proportion of the healthcare expenditure. There are no studies that have analyzed their long-term clinical evolution. OBJECTIVES: To study the characteristics, temporal patterns of readmissions and clinical evolution of patients with multiple hospital admission in the long term. METHODS: A retrospective study was conducted of all hospital admissions in the medical area of the Hospital of Lugo (Spain) between January 1, 2000 and December 31, 2012, based on data from the center's minimum basic data set. RESULTS: A total of 139,249 hospital admissions for 62,515 patients were studied. Six hospital admissions were recorded for 6.4% of the patients. The overall mortality rate was 16% (9982 patients). The readmissions rate steadily increased with each new admission, from 48% after the first event to 74.6% after the fifth. The rate of hospital readmission before 30days increased from 18.3% in the second admission to 36.3% in the sixth. The number of chronic diseases increased from 3.1 (SD, 2) in the first hospital admission up to 4.9 (2.8) in the sixth. The Department of Internal Medicine treated a third of all hospital admissions. In the sixth hospitalization, conditions associated with admission in Internal Medicine were CIRS score, age, heart failure, COPD, dementia, diabetes, atrial fibrillation and anemia. CONCLUSIONS: Patients with multiple hospital admissions are complex patients whose temporal pattern of readmissions changes with time, such that each hospital admission constitutes a factor facilitating the next.

Electrocardiographic abnormalities in centenarians: impact on survival.

BACKGROUND: The centenarian population is gradually increasing, so it is becoming more common to see centenarians in clinical practice. Electrocardiogram abnormalities in the elderly have been reported, but several methodological biases have been detected that limit the validity of their results. The aim of this study is to analyse the ECG abnormalities in a prospective study of the centenarian population and to assess their impact on survival. METHOD: We performed a domiciliary visit, where a medical history, an ECG and blood analysis were obtained. Barthel index (BI), cognitive mini-exam (CME) and Charlson index (ChI) were all determined. Patients were followed up by telephone up until their death. RESULTS: A total of 80 centenarians were studied, 26 men and 64 women, mean age 100.8 (SD 1.3). Of these, 81% had been admitted to the hospital at least once in the past, 81.3% were taking drugs (mean 3.3, rank 0-11). ChI was 1.21 (SD 1.19). Men had higher scores both for BI (70 -SD 34.4- vs. 50.4 -SD 36.6-, P = .005) and CME (16.5 -SD 9.1- vs. 9.1 -SD 11.6-, P = .008); 40.3% of the centenarians had anaemia, 67.5% renal failure, 13% hyperglycaemia, 22.1% hypoalbuminaemia and 10.7% dyslipidaemia, without statistically significant differences regarding sex. Only 7% had a normal ECG; 21 (26.3%) had atrial fibrillation (AF), 30 (37.5%) conduction defects and 31 (38.8%) abnormalities suggestive of ischemia, without sex-related differences. A history of heart disease was significantly associated with the presence of AF (P = .002, OR 5.2, CI 95% 1.8 to 15.2) and changes suggestive of ischemia (P = .019, OR 3.2, CI 95% 1.2-8.7). Mean survival was 628 days (SD 578.5), median 481 days. Mortality risk was independently associated with the presence of AF (RR 2.0, P = .011), hyperglycaemia (RR 2.2, P = .032), hypoalbuminaemia (RR 3.5, P < .001) and functional dependence assessed by BI (RR 1.8, P = .024). CONCLUSION: Although ECG abnormalities are common in centenarians, they are not related to sex, functional capacity or cognitive impairment. The only abnormality that has an impact on survival is AF.

Ferric carboxymaltose with or without erythropoietin for the prevention of red-cell transfusions in the perioperative period of osteoporotic hip fractures: a randomized contolled trial. The PAHFRAC-01 project.

BACKGROUND: Around one third to one half of patients with hip fractures require red-cell pack transfusion. The increasing incidence of hip fracture has also raised the need for this scarce resource. Additionally, red-cell pack transfusions are not without complications which may involve excessive morbidity and mortality. This makes it necessary to develop blood-saving strategies. Our objective was to assess safety, efficacy, and cost-effictveness of combined treatment of i.v. ferric carboxymaltose and erythropoietin (EPOFE arm) versus i.v. ferric carboxymaltose (FE arm) versus a placebo (PLACEBO arm) in reducing the percentage of patients who receive blood transfusions, as well as mortality in the perioperative period of hip fracture intervention. METHODS/DESIGN: Multicentric, phase III, randomized, controlled, double blinded, parallel groups clinical trial. Patients > 65 years admitted to hospital with a hip fracture will be eligible to participate. Patients will be treated with either a single dosage of i.v. ferric carboxymaltose of 1 g and subcutaneous erythropoietin (40.000 IU), or i.v. ferric carboxymaltose and subcutaneous placebo, or i.v. placebo and subcutaneous placebo. Follow-up will be performed until 60 days after discharge, assessing transfusion needs, morbidity, mortality, safety, costs, and health-related quality of life. Intention to treat, as well as per protocol, and incremental cost-effectiveness analysis will be performed. The number of recruited patients per arm is set at 102, a total of 306 patients. DISCUSSION: We think that this trial will contribute to the knowledge about the safety and efficacy of ferric carboxymaltose with/without erythropoietin in preventing red-cell pack transfusions in patients with hip fracture.

[Course of alcohol withdrawal syndrome in a general hospital]. / Curso temporal del síndrome de abstinencia alcohólica en un hospital general.

INTRODUCTION AND OBJECTIVE: There is little information available regarding the course of alcohol withdrawal syndrome in a general hospital. The aim of this study was to analyse the timing of the most important clinical features attributed to alcohol withdrawal, as well as their prognostic implications. MATERIAL AND METHOD: A cohort study of patients with a diagnosis of alcohol withdrawal syndrome was carried out at the Xeral Hospital in Lugo (Spain) between 1987 and 2003, in accordance with DSM IV-TR criteria. Data on clinical characteristics and course were collected, with special attention to the timing of significant events. RESULTS: A total of 539 episodes were studied in 436 patients: 156 cases of alcohol withdrawal syndrome and 383 of alcohol withdrawal delirium. Mean time of abstinence until the diagnosis of alcohol withdrawal syndrome was 54 hours (D.T. = 31.1). Seizures occurred at 35 hours (D.T. = 23.3) after abstinence. The alcohol withdrawal syndrome lasted for 46.4 hours (D.T. = 23.1) after diagnosis. In cases in which delirium tremens developed, this occurred at 46.4 hours (D.T. = 23.1), and lasted 73.9 hours (D.T. = 41.5). Patients needing intensive care were admitted to the ICU 40.8 hours (D.T. = 60) after the diagnosis of alcohol withdrawal syndrome. The clinical features of alcohol withdrawal syndrome tended to be more prolonged in patients admitted with a medical or surgical diagnosis other than withdrawal syndrome than in those admitted because of withdrawal syndrome itself. CONCLUSIONS: The natural history of alcohol withdrawal syndrome in a general hospital setting and the timings of its principal events follow a clearly recognizable pattern. This knowledge can help to provide better assessment in relation to the monitoring and treatment of these patients.

Curso temporal del síndrome de abstinencia alcohólica en un hospital general / Course of alcohol withdrawal syndrome in a general hospital

Introducción y objetivo: Existe poca información sobre el curso temporal del síndrome de abstinencia alcohólica en el ámbito de un hospital general. El objetivo de este estudio es saber qué manifestaciones son atribuibles a la abstinencia y en qué momento de su evolución, así como sus implicaciones pronósticas. Material y método: estudio de cohortes sobre los enfermos diagnosticados de síndrome de abstinencia alcohólica en el Hospital Xeral de Lugo entre 1987 y 2003, según criterios del manual DSM IV-TR. Para cada caso se registraron datos clínicos y de seguimiento, con especial atención a los intervalos temporales de aparición y duración de sus manifestaciones. Resultados: Se estudiaron 539 episodios en 436 pacientes: 156 casos de síndrome de abstinencia no complicado y 383 casos de delirium tremens. El tiempo medio de abstinencia hasta el diagnóstico de síndrome de abstinencia alcohólica fue 54,4 horas (D.T. = 31,1). Las crisis comiciales aparecieron 35 horas (D.T. = 23,3) desde el cese de la ingesta. La duración del síndrome de abstinencia no complicado desde el diagnóstico fue 46,4 horas (D.T. = 23,1). Cuando evolucionaron a delirium tremens, estese diagnosticó a las 40,2 horas (D.T. = 29,4), y se prolongó durante 73,9 horas (D.T. = 41,5). Cuando fue preciso el traslado a la UCI, éste se produjo a las 40,8 horas (D.T. = 60) desde el diagnóstico de síndrome de abstinencia. Los enfermos en los que el síndrome de abstinencia alcohólica complicó un ingreso por otro motivo, presentaron manifestaciones clínicas más prolongadas que los que ingresaron por abstinencia. Conclusiones: las manifestaciones clínicas del síndrome de abstinencia alcohólica siguen una pauta evolutiva claramente reconocible. Su conocimiento puede ayudar a una mejor planificación de su atención y tratamiento (AU)
