Cuestionario para evaluar en médicos conductas, conocimientos y actitudes sobre la higiene de manos

OBJECTIVE Valid and reliable instruments to measure aspects of hand hygiene are needed to determine the current situation and impact of training among health professionals. The main objective of this study was to describe the development of a questionnaire on hand hygiene among health professionals and to analyze the properties of this instrument. METHOD A questionnaire was designed and implemented between January 2010 and March 2011 at the Hospital Clínico San Cecilio (Granada, Spain). The final questionnaire consisted of 44 items that assessed provider behavior before and after contact with the patient, declarative knowledge, and attitudes to hand hygiene. The questionnaire was administered to 113 health professionals. RESULTS A factor analysis was performed. Data were obtained that supported the unidimensionality of the instrument with a general convergence value that explained 39.289% of the total variance and a Cronbachs alpha of 0.784 for the established elements. Significant differences were found in hand hygiene behavior before and after contact with the patient (t=-8,991, p <0.001). Declarative knowledge and attitudes significantly predicted behavior. CONCLUSIONS The questionnaire shows high internal consistency, reliability, and validity and is thus a valid tool to assess behavior, knowledge and attitudes related to hand hygiene in health professionals. This instrument also detects deficiencies in basic knowledge.
