An Importance-Performance Analysis of Primary Health Care Services: Managers vs. Patients Perceptions  [PDF]
Francisco J. Miranda, Antonio Chamorro, Luis R. Murillo, Juan Vega
Journal of Service Science and Management (JSSM) , 2010, DOI: 10.4236/jssm.2010.32028
Abstract: Using importance-performance analysis (IPA), this paper examines the perceptions of patients and managers of health centres of several health care quality services attributes. IPA is an approach to the measurement of customer/user satisfaction which allows for a simple and functional identification of both the strong and the weak aspects, or improvement areas, of a given service. Taking both the importance assigned by users to all relevant aspects of a given service and the perceived performance of the establishment in providing the service, the result is an IPA grid with four quadrants. To the best of our knowledge, this is the first time this methodology has been used to compare the perceptions of health centre patients and managers. The results showed patients and managers to have very different perceptions of all the quality service attributes. Implications for researchers and health centre managers are discussed. The study illustrates the usefulness of the IPA model as a managerial tool in identifying areas to which marketing resources should be allocated in order to improve and enhance the quality of the health centre services provided.

Abstract: the infectious pancreatic necrosis virus, ipnv, is the etiological agent of a highly contagious disease that affects young salmon. the virus is mostly horizontally transmitted; therefore virus quantitation in water is mandatory for a proper sanitary management in the salmon industry as well as in the environment close to the hatcheries. to evaluate the water as a risk factor for ipnv infection in cultured or wild animals, it is necessary to titrate the virus with a suitable sensitivity. therefore, a methodology that allows ipnv concentration to be determined in water using two kinds of ultrafiltration was developed. one, based on the tangential flow of the sample along the surface of a membrane, the other based on the retention of the viral particles at the surface of membranes with controlled pore diameter. reagents and conditions were selected to reduce virus inactivation and/or virus binding to the filters. finally, a protocol was developed that allows the concentration of ipnv in three orders of magnitude and with a total recovery of infectivity to be determined. this method can be performed in less than one day including virus titration using the fluorescent foci method.

Abstract: El virus de la necrosis pancreática infecciosa, virus IPN, es el agente causal de una enfermedad altamente contagiosa que afecta principalmente a peces jóvenes. El virus IPN se transmite mayoritariamente en forma horizontal, por lo cual la cuantificación del virus en el agua es fundamental para un adecuado manejo sanitario de la industria del salmón y del medio ambiente vecino a los sitios de cultivo. Con el fin de establecer el potencial riesgo del agua contaminada con virus IPN es necesario determinar la cantidad de virus activo mediante un procedimiento de detección con la adecuada sensibilidad para cuantificarlo en sus niveles de riesgo mínimos. Para contribuir a satisfacer esta necesidad es que se desarrolló una metodología que permite concentrar al virus desde el agua mediante la combinación de dos tipos de ultrafiltración. Uno basado en el flujo tangencial de la muestra por la superficie de una membrana concentradora y el otro basado en la retención de las partículas virales en la superficie de membranas de poro controlado. Se seleccionaron soluciones y condiciones de aplicación para minimizar la inactivación del virus y/o su unión a los filtros. Finalmente se establece un protocolo mediante el cual es posible concentrar mil veces al virus y con una recuperación total de la infectividad. La aplicación del método no tarda más de un día incluyendo la titulación del virus mediante la técnica de los focos fluorescentes.

Abstract: background: chronic infl ammation and infections are involved in the development and progression of atherosclerotic vascular disease. aim: to evaluate the association between periodontitis and early atherosclerosis. material and methods: fifty-three subjects who received periodontal treatment and regular maintenance for at least 10 years, and 55 subjects with periodontitis but without a history of periodontal treatment were studied. carotid artery intima-media wall thickness (cimt) was measured with high-resolution b-mode ultrasonography. a blood sample was obtained to measure high sensitivity c-reactive protein, fibrinogen, lipoprotein cholesterol, leukocyte count and erythrocyte sedimentation rate. covariates included age, gender, smoking, level of education, body mass index and physical activity. the benzoyl-dl-arginine-naphthylamide (bana) test was used to determine the number of periodontal sites with periodontal pathogens. results: cimt value was significantly higher in subjects with periodontitis than those without it (0.775 ± 0.268 and 0.683 ± 0.131 mm respectively, p = 0.027). c-reactive protein, leukocyte count and percentage of sites with periodontal pathogens were also significantly higher in subjects with periodontitis. regression analysis identified age, periodontitis, and smoking as independent predictors of cimt. conclusions: these results suggest that untreated periodontitis is associated with early atherosclerotic carotid lesions and higher levels of infl ammatory markers.

Abstract: Fundamento. Analizar, en relación a la confidencialidad, los conocimientos, comportamientos y opiniones del personal médico y de enfermería asistente a los 13 seminarios impartidos sobre este tema en el Hospital Virgen del Camino de Pamplona en el a o 2002. Material y métodos. Administración, antes del inicio de cada seminario, de una encuesta de 11 preguntas cerradas para su cumplimentación anónima. Resultados. Un 93,0% de los 244 asistentes respondieron la encuesta (128 médicos y 99 enfermeras). El 92,1% de los profesionales entiende qué es la intimidad, pero un 58,1% no conoce ninguna de las leyes que la regulan. El 87,5% de los facultativos sabe cuándo es legítimo acceder a los datos de un paciente, pero reconocen comportamientos contrarios en un porcentaje que va aumentando con la edad, desde un 12,5% en el grupo de menos de 31 a os hasta el 51,9% en los mayores de 50 a os. Entre el personal de enfermería se recogen prácticas más correctas aun cuando muestran un conocimiento teórico peor sobre estas cuestiones. Un 49,7% de los profesionales ingresaría en otro centro si quisiera que su diagnóstico no se divulgara entre sus compa eros y el 92,2% considera el comentario informal de pasillo la vía más frecuente de ruptura de la confidencialidad en el hospital. Conclusión. Parece oportuno recordar en nuestro hospital la responsabilidad ética y legal en relación a la confidencialidad y propiciar la reflexión de los profesionales sobre estas cuestiones con el fin de mejorar esta dimensión clave de la atención sanitaria.

Abstract: Introducción: Existen pocos estudios que hayan evaluado la eficacia y la seguridad de los sustitutivos de comidas para perder peso. Objetivo: Evaluar la eficacia y la seguridad de un programa de pérdida de peso que incluía productos sustitutivos de comidas. Métodos: Se evaluó el efecto de una dieta hipocalórica versus una dieta hipocalórica que incluía sustitutivos de comidas en 55 voluntarios con sobrepeso u obesidad grado I. Los sujetos fueron distribuidos en un grupo control (dieta hipocalórica) o un grupo de intervención (dieta hipocalórica con sustitutivos de comidas) durante 8 semanas. Se registraron datos antropométricos, hábito tabáquico y nivel de actividad física. También se realizaron extracciones sanguíneas para evaluar cambios bioquímicos al inicio del estudio, a las 4 semanas y al final del estudio. Resultados: El grupo control perdió 3,97 kg de media, mientras que en el grupo intervención se observó una pérdida de 4,44 kg, no siendo estas diferencias estadísticamente significativas entre grupos. Otros parámetros antropométricos como el perímetro de la cintura y el perímetro de la cadera también disminuyeron en ambos grupos, aunque sin diferencias entre grupos. Se observó una disminución estadísticamente significativa (p = 0,041) en los valores de triglicéridos, aunque también sin diferencias entre grupos. Discusión: Los sustitutivos de comidas, dentro de un programa dietético controlado, fueron tan eficaces y seguros para perder peso y modificar otros parámetros antropométricos como el tratamiento dietético convencional sin sustitutivos. Background: There are scarce data about the efficacy and security of meal replacement products as a strategy to weight loss. Aim: To evaluate the efficacy and safety of a weight loss program that includes meal replacement products. Methods: We evaluated the effect of a hypocaloric diet versus a hypocaloric diet that includes meal replacement products in 55 overweight or type I obese patients. Patients were distributed to a control group (hypocaloric diet) or an intervention group (hypocaloric diet with meal replacement products) during 8 weeks. We registered anthropometric data, smoke habit and level of physical activity. We also studied biochemical parameters at the beginning of the study, at 4th week of the study and at the end of the same. Results: The control group lost 3.97 kg, while in the intervention group we observed a loss of 4.44 kg. These differences were not statistically significant between groups. Other anthropometric parameters as waist and hip perimeters diminished also in both groups, wi
