[Design and validation of the scale to assess the fragility of chronic patients]

To create a scale and tool that allows us to measure the fragility of the chronic patient.

Observational study on the area's chronicles.

Between January 2011 and December 2015, a population of 2108 individuals. Data were collected from the medical history and expressed application for the registration of fragile patients, on structured data collection sheet.

Fragile subjects of the North Sanitary Area of Malaga.

Design and validation of a scale.

Study variables.

Antequera Fragility Scale (EPADI) consisting of five criteria / factors: age, Pfeiffer, Barthell, Charlson, sociofamiliar and pluripatological. Accessibility outcome variables were used as prediction variables. Quantitative variables are described by mean and standard deviation. The qualitative variables are presented in frequencies along with their percentages. To obtain a predictive model of resource utilization the sample was divided into two subsamples of equal size.

From the variables of interest by experts, univariate predictors were identified in the use of resources in the sample M_EPADI1, to construct a model of multivariate logistic regression that allows to predict the resource utilization. For the validation of the scale, the sample M_EPADI2 was used.

It was verified that the criteria used in our scale are adequate to define the fragility, therefore the EPADI scale perfectly values the degree of fragility of chronic users based on the resources consumed.
