Validación de la versión española del cuestionario sobre la práctica basada en la evidencia en enfermería

Background: The lack of adequate instruments prevents the possibility of assessing the competence of health care staff in evidence-based decision making and further, the identification of areas for improvement with tailored strategies. The aim of this study is to report about the validation process in the Spanish context of the Evidence-Based Practice Questionnaire (EBPQ) from Upton y Upton. Methods: A multicentre, cross-sectional, descriptive psychometric validation study was carried out. For cultural adaptation, a bidirectional translation was developed, accordingly to usual standards. The measuring model from the questionnaire was undergone to contrast, reproducing the original structure by Exploratory Factorial Analysis (EFA) and Confirmatory Factorial Analysis (CFA), including the reliability of factors. Results: Both EFA (57.545% of total variance explained) and CFA (chi2=2359,9555; gl=252; p<0.0001; RMSEA=0,1844; SRMR=0,1081), detected problems with items 7, 16, 22, 23 and 24, regarding to the original trifactorial version of EBPQ. After deleting some questions, a reduced version containing 19 items obtained an adequate factorial structure (62.29% of total variance explained), but the CFA did not fit well. Nevertheless, it was significantly better than the original version (chi2=673.1261; gl=149; p<0.0001; RMSEA=0.1196; SRMR=0.0648). Conclusions: The trifactorial model obtained good empiric evidence and could be used in our context, but the results invite to advance with further refinements into the factor “attitude”, testing it in more contexts and with more diverse professional profiles.

Construcción y validación de un cuestionario para medir conductas, conocimientos y actitudes sobre la higiene de las manos en personal sanitario en formacion.

Background: Hand hygiene in the health context is a complex behaviour. There have been rarely given the role of the knowledge and attitudes as predictors of hand hygiene behaviour. The main objective of this work is the description of the development of a questionnaire on hand hygiene and the analysis of their measurement properties. Method: An instrument which was designed and validated a questionnaire. It was held in January 2009. It finally has had 50 items that assess risk behaviour intention before and after contact with the patient, declarative knowledge and attitudes about hand hygiene. It has been applied to 431 students of health sciences at the University of Granada. Results: There were three factor analysis, ultimately obtaining a general convergence value that explains 46.01% of the total variance and high reliability (a=0,843). There is correlation between knowledge and behavior intentions before and after patient contact (p <0.01).In turn, the attitude correlates only with behavioral intention before (p <0.05). The hand hygiene behavior refers to a higher mean after the completion of various health activities before the same (4.26 and 3.96 respectively). Both declarative knowledge and attitudes significantly predict behavioral intention, in particular the conduct before the contact with the patient (R2 = 0.100, standardized Beta 0.256 for knowledge and 0.145 for attitudes). Conclusions: The questionnaire shows high internal consistency. We have obtained a valid tool for assessing risk behavior, knowledge and attitudes about students’ hand hygiene in health sciences. The tool detects deficiencies in basic skills in students.

Efectos de la deficiencia de yodo sobre variables intelectuales en una población infantil.

An association between severe iodine deficiency and poor mental development has been found in many studies. We examined the relationship between moderate or mild iodine deficiency and intellectual capacity in order to determine whether problems common to severe iodine deficiency (including mental retardation) also emerge in a more subtle form. We also wished to know whether the classic methodology (comparing iodine-deficient zones with nondeficient zones) is the most adequate, and propose to combine this grouping by zones with urinary iodine presented by individuals in each zone. We measured IQ, manipulative and verbal capacity, attention, visual motor ability and disruptive behaviour, variables that have barely been studied in this kind of investigations. The sample comprised 760 schoolchildren from the province of Jaén (southern Spain). Our results show that children with low levels of iodine intake and with urinary iodine concentration lower than 100 microg/litre had a lower IQ and displayed more disruptive behaviour than children with high levels of the criteria. The other variables were not associated with iodine deficiency.

Recambios en un solo tiempo de prótesis de cadera y rodilla sobre terreno contaminado: nuestra experiencia

Objective: Evaluate the results obtained in the simultaneous replacement of a septic arthroplasty or a second septic replacement (implanting the prosthesis in a contaminated eld). Material and method: Series of 17 cases, with a mean age of 66.8 years and average follow-up of 49 months. The exclusion criteria were serious immunological depression and unknown germ or not sensitive to at least three antibiotics. After the intervention, the corresponding antibiotics were administered between six weeks and three months. Recovery was established as the normality for infection indicator variables at least nine months after the replacement. Results: 14 patients developed towards total recovery (follow-up at least 9 months and maximum 84 months). 3 cases presented relapse, all three carriers of Staphylococcus epidermidis (at 1, 3 and 7 months of follow-up respectively). The success percentage is 82.41% (average follow-up of 49 months). Conclusions: Simultaneous replacements is an interesting option for patients with plural pathologies as it o"ers a single operation, less morbidity, quicker return to activities to restore normal function and less associated costs

Nuevos datos sobre fibrilación auricular, observaciones al estudio OFRECE. Respuesta

We appreciate the interest shown by Vidal-Pérez et al. in our article published recently in Revista Española de Cardiología,1 which provides us with an opportunity to present some interesting additional information not included in the article itself. We agree on the importance of knowing the thromboembolic risk of the population included in the OFRECE study, both for patients with a diagnosis of atrial fibrillation and for the general population. In our study, the mean (standard deviation) CHADS2 and CHAD2DS2-VASc of patients with atrial fibrillation was 2.3 (1.3) and 3.8 (1.6), respectively. In the general population, the mean (standard deviation) CHADS2 and CHAD2DS2-VASc of patients with atrial fibrillation was 0.8 (1) and 1.8 (1.5), respectively. The distribution of both scales is in agreement with that of the Val-FAAP and AFABE studies,2, 3 although the similarity is greater in the 2 population-based studies (Figure). These data are, we believe, relevant because they show that the level of risk in the population with atrial fibrillation is very similar to that of the populations included in clinical trials with new oral anticoagulants. In addition, an increasing body of evidence suggests that thromboembolic risk, as measured with these scales in the population without a diagnosis of atrial fibrillation, is associated with the onset of events.

Efecto del phlebodium decumanum y de la coenzima q10 sobre el rendimiento deportivo en jugadores profesionales de voleibol

INTRODUCTION: Physical training programmes are based on provoking transitory states of fatigue in order to induce super compensation by the biological systems involved in the activity, in order to improve the athlete's medium-long term performance. The administration of nutritional supplements with antioxidant and immunomodulatory properties, such as Phlebodium decumanum and coenzyme Q10, can be a very advantageous means of achieving recovery from the inflammation and tissue damage caused by the stress of prolonged, intense exercise. METHODOLOGY: An experimental, longitudinal, double- blind experiment was conducted, with three randomised groups obtained from a sample of 30 male volleyball players (aged 22-32 years) at the University of Granada, with a high level of training (17 hours a week during the 6 months preceding the study). The effects were then evaluated of a month-long physical training programme, common to all the study groups, associated with the simultaneous administration of the following nutritional supplements: Phlebodium decumanum (4 capsules of 400 mg/capsule, daily), Experimental Group 1; Phlebodium decumanum (same dose andchedule as Group 1) plus coenzyme Q10 (4 capsules of 30 mg/ capsule, daily), Experimental Group 2; a placebo substance, Control Group. The following dependent blood variables were examined to assess the effects of the intervention on the basal immune and endocrine-metabolic profile: cortisol and interleukin-6, both related to the axis of exercise-induced stress; and lactic acid and ammonium, related essentially to the anaerobic metabolism of energy. RESULTS: All the study groups presented favourable adaptive changes with respect to the endocrine-metabolic and immune profile, as reflected by a significant decrease in the post-test concentrations of cortisol, interleukin 6, lactic acid and ammonium, compared to the values recorded before the physical activity with/without nutritional supplement, per protocol. The groups that achieved the most favourable profile were those which had received nutritional supplementation, rather than the placebo, and among the former, those which had received the double- strength supplement with Phlebodium decumanum plus coenzyme Q10. CONCLUSIONS: The intake of Phlebodium decumanum plus coenzyme Q10 for 4 weeks produced protective effects on the endocrine-metabolic and immune profile, which we attribute to the immunomodulatory and antioxidant properties of these substances, which are highly beneficial not only in terms of delaying fatigue and improving athletic performance, but also in reducing the risk of injuries associated with high intensity exercise.

El proyecto EMECAM: Estudio Multicéntrico Español sobre la Relación entre la Contaminación Atmosférica y la Mortalidad. Antecedentes, participantes, objetivos y métodología.

In recent years, a growing number of studies suggests that increases in air pollution levels may have short-term impact on human health, even at pollution levels similar to or lower than those which have been considered to be safe to date. The different methodological approaches and the varying analysis techniques employed have made it difficult to make a direct comparison among all of the findings, preventing any clear conclusions from being drawn. This has led to multicenter projects such as the APHEA (Short-Term Impact of Air Pollution on Health. A European Approach) within a European Scope. The EMECAM Project falls within the context of the aforesaid multicenter studies and has a wide-ranging projection nationwide within Spain. Fourteen (14) cities throughout Spain were included in this Project (Barcelona, Metropolitan Area of Bilbao, Cartagena, Castellón, Gijón, Huelva, Madrid, Pamplona, Seville, Oviedo, Valencia, Vigo, Vitoria and Saragossa) representing different sociodemographic, climate and environmental situations, adding up to a total of nearly nine million inhabitants. The objective of the EMECAM project is that to asses the short-term impact of air pollution throughout all of the participating cities on the mortality for all causes, on the population and on individuals over age 70, for respiratory and cardiovascular design causes. For this purpose, with an ecological, the time series data analyzed taking the daily deaths, pollutants, temperature data and other factors taken from records kept by public institutions. The period of time throughout which this study was conducted, although not exactly the same for all of the cities involved, runs in all cases from 1990 to 1996. The degree of relationship measured by means of an autoregressive Poisson regression. In the future, the results of each city will be combined by means of a meta-analysis.
