[The 2013 Seville Consensus Document on alternatives to allogenic blood transfusion. An update on the Seville Document]. / 2013. Documento Sevilla de Consenso sobre Alternativas a la Transfusión de Sangre Alogénica. Actualización del Documento Sevilla.

Since allogeneic blood transfusion (ABT) is not harmless, multiple alternatives to ABT (AABT) have emerged, though there is great variability in their indications and appropriate use. This variability results from the interaction of a number of factors, including the specialty of the physician, knowledge and preferences, the degree of anemia, transfusion policy, and AABT availability. Since AABTs are not harmless and may not meet cost-effectiveness criteria, such variability is unacceptable. The Spanish Societies of Anesthesiology (SEDAR), Hematology and Hemotherapy (SEHH), Hospital Pharmacy (SEFH), Critical Care Medicine (SEMICYUC), Thrombosis and Hemostasis (SETH) and Blood Transfusion (SETS) have developed a Consensus Document for the proper use of AABTs. A panel of experts convened by these 6 Societies have conducted a systematic review of the medical literature and have developed the 2013 Seville Consensus Document on Alternatives to Allogeneic Blood Transfusion, which only considers those AABT aimed at decreasing the transfusion of packed red cells. AABTs are defined as any pharmacological or non-pharmacological measure aimed at decreasing the transfusion of red blood cell concentrates, while preserving patient safety. For each AABT, the main question formulated, positively or negatively, is: « Does this particular AABT reduce the transfusion rate or not?¼ All the recommendations on the use of AABTs were formulated according to the Grades of Recommendation Assessment, Development and Evaluation (GRADE) methodology.

[Are drugs worth their cost?]. / ¿Valen los medicamentos lo que cuestan?

Drugs constantly jeopardize the balance among Bioethical Principles governing Healthcare. Their correct use implies more than a correct clinical diagnosis and an academic prescription and demands thorough coordination among all healthcare levels (Regulatory Agencies, the State, the Pharmaceutical Industry and professionals) and the necessary incentive for the research and development process to provide true therapeutic innovations. The interannual growth of Pharmaceutical Expenditure in the public sector in the last few years has greatly exceeded growth in the consumer price index and the gross domestic product. The economic problem of drugs utilization therefore centers on their opportunity cost and on their impact on the sustainability of the system overall. Cost-utility, as an accepted principle for the incorporation and use of new technologies is not always taken into account in prioritization, decision-making and interventions.

Incidencia de resultados negativos de medicación en un servicio de urgencias hospitalario y factores asociados / Incidence rate of adverse drug effects in a hospital emergency unit and its associated factors

Introducción Los resultados negativos de la medicación (RNM) motivan entre un 0,86–38,2% de las urgencias hospitalarias y en un alto porcentaje son evitables. La prescripción racional y el seguimiento farmacoterapéutico reducen la aparición de estos problemas de salud. Método Estudio en el servicio de urgencias de un hospital de tercer nivel con selección de pacientes por muestreo aleatorio bietápico. La información se obtuvo de un cuestionario validado y de la historia clínica. Los datos se estructuraron dentro del siguiente esquema causa-efecto: 1) factores potenciales de riesgo de un RNM; 2) efectos provocados de manera plausible por fármacos; 3) consecuencias del RNM, y 4) potenciales factores de confusión. La información obtenida fue evaluada según la metodología Dáder por cuatro evaluadores independientes. Resultados Se incluyeron 840 pacientes en el estudio, de los cuales el 33% acudió a urgencias por un RNM. Los RNM se observaron con mayor frecuencia en las mujeres, con mayor consumo de fármacos, en los pacientes mayores, en aquellos con alguna enfermedad de base y en los pertenecientes a clases sociales más desfavorecidas. Los factores que determinan el riesgo de aparición de los RNM son la cantidad de medicamentos consumidos, el sexo y el índice de prácticas de la salud. Discusión Un tercio de las urgencias hospitalarias fueron debidas a RNM y se asociaron a los mismos factores que otros estudios (número de fármacos consumidos, sexo femenino, edad y clase social). Además, se observó un predominio de los RNM en los pacientes con valores bajos del índice de prácticas de la salud y en aquellos con enfermedades de base (AU)

Introduction Adverse drug effects (ADEs) are the reason for 0.86% to 38.2% of hospital emergency admissions, and a large percentage of them are avoidable. Rational prescription and pharmacotherapy monitoring decrease the appearance of such health problems. Method Study performed in a tertiary hospital emergency unit with patients selected using a two-phase random sample. The information was obtained from a validated questionnaire and from the clinical history. The data were grouped according to the following cause-effect schema: 1-Potential risk factors for an ADE. 2-Effects likely to be caused by drugs. 3-Consequences of ADEs. 4-Potential confounding factors. The information obtained was evaluated by four independent evaluators using the Dader method.Results840 patients were included in the study, and 33% of them came to the emergency unit due to an ADE. ADEs were more frequently observed in female patients, those with higher drug consumption, older patients, those with an underlying illness and in those from underprivileged backgrounds. The factors determining risk of an ADE are the quantity of drugs consumed, sex and the health practices index. Discussion One third of hospital emergency admissions were due to ADEs, and these were associated with the same factors found in other studies (number of drugs consumed, female sex, age and social background). In addition, we observed that ADEs are predominant in patients with low values on the health practices index, and in those with underlying illnesses (AU)

INTRODUCTION: Adverse drug effects (ADEs) are the reason for 0.86% to 38.2% of hospital emergency admissions, and a large percentage of them are avoidable. Rational prescription and pharmacotherapy monitoring decrease the appearance of such health problems. METHOD: Study performed in a tertiary hospital emergency unit with patients selected using a two-phase random sample. The information was obtained from a validated questionnaire and from the clinical history. The data were grouped according to the following cause-effect schema: 1-Potential risk factors for an ADE. 2-Effects likely to be caused by drugs. 3-Consequences of ADEs. 4-Potential confounding factors.

ADEs were more frequently observed in female patients, those with higher drug consumption, older patients, those with an underlying illness and in those from underprivileged backgrounds. The factors determining risk of an ADE are the quantity of drugs consumed, sex and the health practices index. DISCUSSION: One third of hospital emergency admissions were due to ADEs, and these were associated with the same factors found in other studies (number of drugs consumed, female sex, age and social background).

[Assessing an automated dispensation system in the emergency department of a level III-hospital]. / Evaluación de un sistema automático de dispensación en el Servicio de Urgencias de un hospital de tercer nivel.

OBJECTIVE: The objective of this work was to describe and to assess an automated drug dispensing system in the emergency department of a level-III hospital. MATERIALS AND METHODS: Sequential implementation of PyxisA(R) commenced in July 2001 in a number of Emergency areas. The addition of a Medanalistâ system speeds up the evaluation of generated information. Analysed variables were classified as: a) logistic: workload distribution; b) financial: cost per emergency patient attended; c) number of pharmaceutical procedures. Statistical descriptors were analysed using the SPSS 10.0 software. RESULTS: 1. Logistic: increased workload in PD and decreased Emergency staff calls. 2. Financial: Consumption in the emergency department was reduced by 12% in 2001. In addition, the number of applications for drugs not included within the hospital formulary decreased. CONCLUSION: The main benefit of this system is the information it provides on drug use. However, the fact that this projectâs implementation increased workload in our department, and that a definitive set-up would require a pharmacy assistant staff member should be considered. Regarding this memberâs work, at least a half-day commitment during implementation stages would be needed to direct this change in mentality. Once the system is set up, time is needed to review and monitor previous day activities, and to analyse generated information monthly.

Synthesis and preliminary pharmacological evaluation of thiophene analogues of viloxazine as potential antidepressant drugs.

A series of eight thienyloxymethylmorpholines, thiophene analogues of viloxazine, have been synthesized by three different routes. The preliminary pharmacological evaluation of this series shows antidepressant properties on the mice models used with a light sedative action. The structure-activity relationship is established in a first approximation.
