ABSTRACT
INTRODUCCIÓN: La higiene de manos es la medida más eficaz para prevenir las infecciones asociadas al cuidado de la salud. Las actitudes hacia esta práctica tan sencilla, influyen en el grado de adherencia. OBJETIVO: Desarrollar y validar un instrumento para evaluar las actitudes hacia la higiene de manos en estudiantes de Licenciatura en Enfermería. MÉTODO: Se realizó un estudio observacional y de corte transversal. Una vez construido el instrumento se realizó la validez de contenido mediante el juicio de expertos. Para la validez de constructo se realizó análisis factorial exploratorio. Posteriormente se calculó la confiabilidad, que incluyó la consistencia interna y la estabilidad del cuestionario. RESULTADOS: Participaron 313 estudiantes de Licenciatura en Enfermería de ocho universidades de Argentina. Se calculó el Kaiser-Meyer-Olkin (KMO = 0,720) y se obtuvo una prueba de esfericidad de Bartlett significativa (x2 = 831,2; = 0,000). El análisis factorial exploratorio determinó la existencia de un único factor. El modelo explicó el 54% de la varianza. Se utilizó la implementación mejorada de la estimación Bayesiana EAP integrada en el programa FACTOR, que fue de 0,85 y se realizó test-retest utilizando análisis de correlación que arrojó un r = 0,64 (p ≤ 0,001). CONCLUSIONES: El cuestionario sobre actitudes hacia la higiene de manos (CAHM) presenta una adecuada validez y confiablidad, por lo que puede ser utilizado para indagar sobre este factor predisponente de adherencia hacia la higiene de manos.
BACKGROUND: Hand hygiene is the most effective measure to prevent health care-associated infections. Attitudes towards this simple practice influence the level of adherence. AIM: To develop and validate an instrument for the evaluation of attitudes towards hand hygiene in nursing students. METHOD: An observational and cross-sectional study was carried out. Once the instrument was constructed, content validity was carried out through expert judgment. For construct validity, exploratory factor analysis was performed. Subsequently, the analysis of construct validity and reliability was calculated, which included the internal consistency and stability of the questionnaire. RESULTS: 313 Nursing undergraduate students from 8 universities in Argentina participated. The Kaiser-Meyer-Olkin (KMO = 0.720) was calculated, and a significant Bartlett sphericity test was obtained (x2 = 831.2; = 0.000). The exploratory factor analysis determined the existence of a single factor. The model explained 54% of the variance. The improved implementation of the Bayesian EAP estimation integrated in the FACTOR program was used, which was 0.85; and test-retest was also performed using correlation analysis that yielded r = 0.64 (p ≤ 0.001). CONCLUSIONS: The Questionnaire on attitudes towards hand hygiene (CAHM) has adequate validity and reliability, so it can be used to investigate this predisposing factor of adherence to hand hygiene.

INTRODUCTION: The EORTC QLQ-INFO25 evaluates the information received by cancer patients. This study assesses the psychometric properties of the QLQ-INFO25 when applied to a sample of Spanish patients. MATERIALS AND METHODS: A total of 169 patients with different cancers and stages of disease completed the EORTC QLQINFO25, the EORTC QLQ-C30 and the information scales of the inpatient satisfaction module EORTC IN-PATSAT32 on two occasions during the patients' treatment and follow- up period. Psychometric evaluation of the structure, reliability, validity and responsiveness to changes was conducted. Patient acceptability was assessed with a debriefing questionnaire. RESULTS: Multi-trait scaling confirmed the 4 multi-item scales (information about disease, medical tests, treatment and other services) and eight single items. All items met the standards for convergent validity and all except one met the standards of item discriminant validity. Internal consistency for all scales (α>0.70) and the whole questionnaire (α>0.90) was adequate in the three measurements, except information about the disease (0.67) and other services (0.68) in the first measurement, as was test-retest reliability (intraclass correlations >0.70). Correlations with related areas of IN-PATSAT32 (r>0.40) supported convergent validity. Divergent validity was confirmed through low correlations with EORTC QLQ-C30 scales (r<0.30). The EORTC QLQ-INFO-25 discriminated among groups based on gender, age, education, levels of anxiety and depression, treatment line, wish for information and satisfaction. One scale and an item showed changes over time. CONCLUSIONS: The EORTC QLQ-INFO 25 is a reliable and valid instrument when applied to a sample of Spanish cancer patients. These results are in line with those of the EORTC validation study.

INTRODUCTION: There are few studies on the effect on quality of life (QL) of cancer-related illness and treatment in elderly patients. The aim of this work was to evaluate prospectively QL in a sample of elderly patients with stages I.III breast cancer who started radiotherapy treatment and compare their QL with that of a sample of younger patients. MATERIALS AND METHODS: Forty-eight patients, > or = 65 years of age completed the European Organization for Research and Treatment of Cancer (EORTC) QL questionnaires QLQ-C30 and QLQ-BR23, and the Interview for Deterioration in Daily Living Activities in Dementia (IDDD) daily activities scale three times throughout treatment and follow-up periods. Clinical and demographic data were also recorded. Fifty patients ages 40-64 years with the same disease stage and treatment modality had previously completed the QL questionnaires. QL scores, changes in them among the three assessments, differences between groups based on clinical factors, and differences between the two samples were calculated. RESULTS: QL scoring was good and stable (>70/100 points) in most areas, in line with clinical data. Light and moderate limitations occurred in global QL and some emotional, sexual, and treatment-related areas. Moderate decreases (10-20) appeared in some toxicity-related areas, which recovered during the follow-up period. Breast-conservation and sentinel-node patients presented higher scores in emotional areas. There were few QL differences among agebased samples. CONCLUSIONS: QL and clinical data indicate radiotherapy was well tolerated. Age should not be the only factor evaluated when deciding upon treatment for breast cancer patients.

INTRODUCTION: This study aims to asses the effectiveness and toxicity of boost radiotherapy concomitant and concurrent cisplatin for patients with locally advanced head and neck cancer (LAHNC). MATERIAL AND METHODS: There were 30 patients included in a prospective, phase II single-institution trial and of whom, 29 were at AJCC stage IV and 1 at stage III. Treatment consisted of radiotherapy acceleration fractionation with concomitant boost, 72 Gy, and 2 cycles of concomitant cisplatin (20 mg/m2/day continuous infusion; days 1-5 and 29-33). Amifostine, (i.v. 200 mg/m2) was administered to 26 prior to the first fraction of radiotherapy. Endpoints of the study were quality-of-life (QL), overall survival, and local control of disease. RESULTS: Complete response (CR) was achieved in 23 patients (77%), 2 patients had partial response (PR) (7%), 4 had no response (13%), and 1 was not evaluated for response. The 2-year overall survival and loco-regional control were 60% and 56%, respectively. Main toxicity was grade 3 or 4 mucositis in 93% of the patients. QL scores (questionnaire QLQC30; version 3.0) and the HN cancer module QLQ-HN35) showed a worsening in areas related to the treatment e.g. dry mouth, problems stretching the mouth, and sticky saliva. CONCLUSIONS: this combination modality is active, but toxic, in the treatment for LAHNC. Concomitant boost radiotherapy is probably, not the best radiotherapy schema for combining with chemotherapy in LAHNC.
