Elección de elementos esenciales de los entornos profesionales de enfermería en Atención Primaria, mediante el cuestionario Practice Environment Scale of the Nursing Work Index (PES-NWI)

Gea Caballero, Vicente Antonio 29 July 2015 (has links)
Objetivo. El cuestionario PES-NWI (31 ítems) mide las características de los entornos para la práctica profesional en enfermería. Las características de estos entornos influyen claramente sobre la calidad de los cuidados que las enfermeras prestan a los usuarios, y en los resultados en los pacientes. Pretendemos analizar y estudiar desde un punto de vista cuali-cuantitativo dicho cuestionario para intentar seleccionar los 10 ítems más relevantes en su contribución a la mejora del entorno profesional, que sean esenciales en la mejora de los cuidados de enfermería en Atención Primaria de Salud (APS). Método. Estudio mixto cuali-cuantitativo en 2 fases: 1. Fase cualitativa: Fenomenológico. Muestreo intencional (bola de nieve) por conveniencia. Técnica de grupo focal (audioconferencia 2 horas) combinada con conteo de resultados (pre y post grupo focal). N=8, expertos en Atención Primaria de Salud según nuestro criterio. Análisis de contenido con QSR Nvivo v10. Septiembre 2013 a mayo 2014. 2. Fase cuantitativa: Estudio observacional, transversal, analítico, multicéntrico. Junio 2014 a febrero 2015. n=269 profesionales asistenciales, muestreo simple aleatorio, en 3 Departamentos de Salud de la Comunitat Valenciana, 2 de ellos con modelo de gestión privado (Elx-Vinalopó y Torrevieja) y 1 de gestión pública (Xàtiva/Ontinyent). Recogida de datos con cuestionario PES-NWI de forma combinada online y presencial. Análisis de datos con SPSS v21. Variables a estudio: socio-demográficas y los 31 ítems del cuestionario. IC 95%. Se utilizaron descriptivos habituales y ANOVA, con análisis factorial de resultados. Se obtuvo consentimiento informado de participantes y permisos de los Comités de ética e investigación de los Departamentos estudiados. Resultados. Fase cualitativa: Se desecharon a priori 10 ítems del cuestionario. Se obtuvo elevado o aceptable consenso en los elementos fundamentales: ítems 2, 15, 20, 31, 6, 11, 14, 18, 26. El 10º ítem se asignó tras análisis de contenido (ítem 19). Fase cuantitativa: Se seleccionaron los 10 ítems (top ten) con mayor % de elecciones; 9 de los 10 ítems coincidieron entre expertos y profesionales asistenciales. El elemento más importante para la mejora del cuidado es el apoyo y liderazgo de gestores. Los departamentos de salud privatizados obtuvieron puntuaciones ligeramente más altas (mejor entorno) respecto al de gestión pública (p<0,001), con alta influencia de la variable edad (p>0,001), así como Ejercer cargos de coordinación/no ejercerlo (p<0,001). Al ajustar por edad, años de experiencia y cargo de coordinación, los departamentos de gestión privada siguen ofreciendo puntuaciones totales más elevadas, con significación especial de la variable edad, que la consideramos explicativa de las diferencias. Alta consistencia interna de nuestros resultados (alfa de Cronbach>0,8 en sus 5 dimensiones), que reproducen la estructura original del cuestionario. Los elementos esenciales propuestos (Top Ten) han mostrado un valor de predicción de la puntuación total del PES-NWI de 31 ítems del 90,7%, aportando información adecuada en 3 de las 5 dimensiones originales (1, 2 y 4); el Top Ten presenta una estructura interna en 3 dimensiones. El Departamento con mejor valoración fue Torrevieja, y el de peor valoración, Xàtiva / Ontinyent. Todos los Departamentos estudiados son considerados entornos positivos para obtener buenos cuidados de enfermería. Conclusiones. Ha sido posible consensuar y seleccionar los 10 elementos esenciales (Top Ten) del cuestionario PES-NWI que más influyen en los entornos profesionales en Atención Primaria de Salud en España. Modificar estos elementos de forma prioritaria permitirá optimizar los entornos laborales para mejorar los cuidados. Estos 10 elementos aportan el 90,7% de la información en cuanto a puntuación total que el cuestionario completo, por lo que consideramos que el Top Ten es una buena herramienta breve de valoración de la calidad de los entornos.

Vernal Pool Mapping and Geomorphology in the Appalachian Mountains of Pennsylvania

Blackman, Taylor Nathaniel 11 June 2019 (has links)
Vernal pools are small seasonally-ponded wetlands that provide crucial habitat for amphibian reproduction and support trophic levels beyond their boundaries. The Ridge and Valley physiographic province in Pennsylvania is known to have vernal pools, but a regional inventory and geomorphology assessment is needed. My research is split into two independent parts focusing on the higher elevation areas of this region to determine vernal pool distribution and characteristics. Vernal pools were mapped using a LiDAR based suitability model and leaf-off aerial imagery interpretation. Four terrain rasters derived from a 1-meter DEM (modified wind modified wind exposure, terrain surface convexity, topographic position index, and a multiresolution index of valley bottom flatness) were used in the suitability model. An analysis of variance (ANOVA) and Tukey's HSD test found a significant difference using the model between terrestrial (non-wetland) habitat and vernal pools. Photo interpretation and field surveying lead to an inventory of 1011 vernal pools. Geomorphology was assessed from 13 variables to determine the best for vernal pool prediction. Three variables were significant for the occurrence and frequency of vernal pools; saddles with higher surface area, 0.6 to 1.5 kilometers between the summits of parallel ridgelines, and the presence of periglacial related solifluction. Vernal pool distribution is greater than previously known and they occur in predictable settings. Further research should focus on how and where vernal pools form, their impact on water quality, role in forest ecology, and ways to legally protect them at the state level. / Master of Science / Vernal pools are seasonally-ponded wetlands that are very important for amphibian reproduction. The Appalachian Mountains of Pennsylvania are known to have vernal pools, but comprehensive inventory is lacking. My research consists of two parts that focus on the higher elevation areas and assess the distribution and qualities of the vernal pools. Vernal pools were mapped using a LiDAR based suitability model and leaf-off aerial imagery interpretation. Statistical analysis was completed to prove that there was a significant difference in terrain morphology between non-wetland habitat and vernal pools. This research resulted in a total inventory of 1011 vernal pools. Results found that vernal pools were likely occur in landscape positions with higher surface area, 0.6 to 1.5 kilometers between the summits of parallel ridgelines, and the presence of topographic features indicative of glacial processes. Vernal pools are much more abundant than previously known and they occur in predictable settings. Further research could focus on the formation of vernal pools, impact on water quality, role in forest ecology, and ways to legally protect them at the state level.

Analysis of the practice environment of nurses in a public hospital

Motaung, Mmatimeng Catherine 08 1900 (has links)
The National Health Act aims to protect the health care users and workers by ensuring that their work environments are protected against injuries. Practice environment is described as a physical, social and psychological characteristic of a work setting in which policies, procedures and systems are designed so that employees can meet the organisational objectives and achieve personal satisfaction in their work environment. The aim of the study was to describe and analyze characteristics of the practice environment of nurses. A quantitative descriptive study was conducted in a public hospital in Gauteng Province. Practice Environment Scale-Nursing Working Index (PES-NWI) questionnaires were distributed to 207 nurses who were proportionately stratified. Data was analysed using the SPSS version 25. Findings identified gaps of the current characteristics of the practice environment and developed strategies that will assist managers to enhance practice environment. There was alignment and correlation between the means, standard deviation and the frequencies which were drawn from the findings. The overall Cronbach’s alpha was 89% which confirmed the internal consistency of the instrument. The majority of the variables demonstrated statistical significance which had a p value of 0.001. In conclusion, practice environment affects all health care professionals although the study only analyzed the practice environment of nurses. / Health Studies / M. P. H.
