This study evaluates the validity and reliability of the Work Ability Index (WAI) in Argentina. An instrument was applied to 100 workers, all agents of Primary Health Care in the county of General Pueyrredón. In the construct validity, the dimensional structure was studied by means of exploratory factor analysis, based on a polychoric matrix and parallel analysis to obtain the number of factors. In the correlation validation, the Spearman correlation was estimated between the WAI and the dimensions of the 36-Item Short Form Health Survey (SF-36). The reliability assessment was measured by Cronbach's alpha estimate. The result of the internal consistency of the scale was 0.80, indicating acceptable reliability. The WAI score yielded the following results: 12% moderate, 50% good and 38% optimal. In the validation process, a three-dimensional structure was identified which accounts for 66% of the total variance of the data through the main components. The theoretical assumptions of the construct validity confirmed the direct and significant correlation between WAI scores and the dimensions of health status assessment, with the highest value in the physical functioning dimension (0.478) and the lowest in the bodily pain dimension (-0.218). It was concluded that the WAI, translated and adapted into Spanish, showed adequate psychometric properties and can therefore be used in association studies between aspects of work and their impact on health.
The prevalence of hospital infections, the distribution of primary infection sites, and the associations with risk factors were similar to those observed by other authors in several countries. It is important to understand the local and national issues prior to initiating a surveillance program. Surveys such as these, with a national scope and administered by the State, are one way of motivating, raising awareness, and building capacity.
Hospital antibiotic use in Argentina has not been described. We present results of point prevalence surveys on antibiotic use conducted in 109 Argentinian hospitals in November 2018 and submitted to the National Program of Epidemiology and Control of Hospital-Acquired Infections, and we discuss potential areas for improvement.
Este estudio evalúa la validez y confiabilidad del Índice de Capacidad para el Trabajo (ICT) en Argentina. El instrumento se aplicó a 100 trabajadores, agentes de Atención Primaria de la Salud del Partido de General Pueyrredón. En la validez del constructo se investigó la estructura dimensional por medio de análisis factorial exploratorio, a partir de una matriz policórica y un análisis paralelo para la obtención del número de factores. En la validación correlacional se estimó la correlación de Spearman entre el ICT y las dimensiones del Cuestionario de Salud SF-36. La evaluación de confiabilidad se midió a través del estimador Alfa de Cronbach. El resultado de la consistencia interna de la escala fue 0,80, indicando una fiabilidad aceptable. La puntuación de ICT arrojó como resultado: moderado 12%, bueno 50% y óptimo 38%. En el proceso de validación se identificó una estructura de tres dimensiones que explica el 66% de la variación total de los datos a través de los componentes principales. Los supuestos teóricos de la validez del constructo confirmaron la correlación directa y significativa con las puntuaciones del ICT y las dimensiones de evaluación del estado de salud, siendo el mayor valor función física (0,478) y menor la dimensión dolor (-0,218). Se concluyó que el ICT, traducido y adaptado al español, mostró propiedades psicométricas adecuadas pudiendo ser utilizada en estudios de asociación entre aspectos de trabajo y su impacto en la salud.
