ABSTRACT

El objetivo del presente estudio fue proponer un instrumento para medir el clima laboral en la Fuerza Aérea Colombiana. Para ello se diseñó el cuestionario de clima laboral, se evaluaron las características psicométricas y se estableció su utilidad como instrumento de medida. El estudio fue de tipo instrumental, con la participación de 3272 de sus funcionarios, diferenciados por grupos de rango, dependencia, jefatura y bases en el ámbito nacional. Se realizó el análisis de ítems para identificar la potencia discriminativa de cada uno de los ítems, para diferenciar entre quiénes tienen alta percepción de un buen clima laboral y los que no la tienen; la homogeneidad y la consistencia interna. Todas las escalas obtuvieron un alpha mayor a 0,72 y del análisis de cada ítem, se propone una escala de 58 elementos. Se concluye que el cuestionario de clima laboral tiene buena capacidad discriminativa y de homogeneidad.


The purpose of the study was to propose an instrument in order to measure the work environment in the Colombian Air Forces. In order to do this, a questionnaire of work environment was designed; then the psychometric characteristics were evaluated and the utility as an instrument of measurement was established. This study was instrumental and 3272 military servants took part in it and were classified according to their rank, branch where they work, if they were the chief of a division and location in the national territory. In order to identify the discriminative potential of each one of the items to differentiate among the military servants who have a high perception of a good work environment and those who do not have it, each item was analyzed. Homogeneity and inner consistency were also studied. All the scales got an alpha bigger than 0,72 and according to each item, a scale of 58 items is proposed. It was concluded that the questionnaire of work environment has a good homogeneity and discriminative capacity.

ABSTRACT

Se determinó la frecuencia y susceptibilidad a los antimicrobianos de Proteus mirabilis, en pacientes con infecciones urinarias, atendidos en el "Hospital Belén de Trujillo", durante el año 2009. Se evaluó un total de 111 muestras de orina, obtenidas mediante la técnica de recolección limpia y sembradas en medios selectivos y diferenciales para el aislamiento de Enterobacteriaceae. A los aislamientos compatibles con el género Proteus se les realizó las pruebas de identificación para P. mirabilis, obteniendo un 6,31% de positividad. Por grupo etario este microorganismo se presentó con un 14,29% en pacientes menores de 15 años; 42,85% de 15 a 50 años y 28,57% en mayores de 50 años; mientras que por sexo P. mirabilis se presentó en un 28,57% en hombres y 71,43% en mujeres. La susceptibilidad a los antimicrobianos de P. mirabilis se realizó mediante el método de Kirby-Bauer, empleando el mediode Mueller-Hinton y usando los discos de antimicrobianos recomendados por el Clinical and Laboratory Standards Institute. P. mirabilis presentó una sensibilidad de 100% a gentamicina e imipenem; 71,43% a cefalotina, amoxicilina/ácido clavulánico, ceftriaxona y ciprofloxacina; y 28,57% a ampicilina y trimetoprima/sulfametoxazol. Se concluyó que P. mirabilis presentó una baja frecuencia como causante de infecciones del tracto urinario y una alta sensibilidad anlos antimicrobianos gentamicina e impenem.


The frequency and antimicrobial susceptibility of Proteus mirabilis was determined in patient with urinary tract infections, treated at the "Hospital Belén de Trujillo", in 2009. A total of 111 urine samples was evaluated, obtained by harvesting technique clean and planted on selective and differential media for isolation of Enterobacteriaceae. To the compatible isolates with Proteus genus was realized identification tests for P. mirabilis, obtaining a 6.31%positivity. By age group this microorganisms is presented with a 14.29% in young patients of 15 years, 42.85% from 15 to 50 years and 28.57% in patients over 50 years, while by sex P. mirabilis was presented in 28.57% and 71.43% in men and women. The Kirby-Bauer method was realized on the antimicrobial susceptibility, using Mueller-Hinton medium and using antimicrobial disc recommended by the Clinical and Laboratory Standards Institute. P. mirabilis had a sensibility of 100% to gentamicin and impenem, 71.43% to cephalothin, amoxicillin/clavulanate, ceftriaxone and ciprofloxacin, and 28.57% to ampicillin and trimethoprim / sulfamethoxazole. It was concluded that P. mirabilis had a low frequency to cause urinary tract infections and high sensibility to gentamicin and imipenem antimicrobial.
