ABSTRACT

INTRODUCTION:

The scarcity of person-centered applications aimed at developing awareness on the risk posed by the COVID-19 pandemic, stimulates the exploration and creation of preventive tools that are accessible to the population.

OBJECTIVE:

To develop a predictive model that allows evaluating the risk of mortality in the event of SARS-CoV-2 virus infection.

METHODS:

Exploration of public data from 16,000 COVID-19-positive patients to generate an efficient discriminant model, evaluated with a score function and expressed by a self-rated preventive interest questionnaire.

RESULTS:

A useful linear function was obtained with a discriminant capacity of 0.845; internal validation with bootstrap and external validation, with 25 % of tested patients showing marginal differences.

CONCLUSION:

The predictive model with statistical support, based on 15 accessible questions, can become a structured prevention tool.
RESUMEN

INTRODUCCIÓN:

La escasez de aplicaciones centradas en la persona y con vistas al desarrollo de la conciencia del riesgo que representa la pandemia de COVID-19 estimula la exploración y creación de herramientas de carácter preventivo accesibles a la población.

OBJETIVO:

Elaboración de un modelo predictivo que permita evaluar el riesgo de letalidad ante infección por el virus SARS-CoV-2.

MÉTODOS:

Exploración de datos públicos de 16 000 pacientes positivos a COVID-19, para generar un modelo discriminante eficiente, valorado con una función score y que se expresa mediante un cuestionario autocalificado de interés preventivo.

RESULTADOS:

Se obtuvo una función lineal útil con capacidad discriminante de 0.845; la validación interna con bootstrap y la externa, con 25 % de los pacientes de prueba, mostraron diferencias marginales.

CONCLUSIÓN:

El modelo predictivo, basado en 15 preguntas accesibles puede convertirse en una herramienta de prevención estructurada.
