Abstract

This paper presents a multi–criteria decision making (MCDM) model for evaluating an Information and Communication Technology (ICT) network system in health care .The competing goals existing in Health Institutions need a special treatment, thus the MCDM approach is essential for identifying ICT network quality of service (QoS) requirements and implications. A pilot study based on user perception is explored involving three categories of hospitals in Chile. Data is collected considering various health sector representatives. The main contribution is the proposed decision methodology to develop criteria for evaluating QoS issues of an ICT network system within a healthcare environment using the Analytical Hierarchy Process (AHP). The results provides a framework to make decisions concerning an information technology networked system, characterizing end users and their needs and enabling tradeoffs in agreement with the institution objectives.

Keywords: AHP, Health service decision support, ICT, MCDM

 

Resumen

Esta publicación presenta un modelo multicriterio de toma de decisiones (MCDM) para evaluar un sistema de información y tecnología de comunicación (TIC) en un servicio de salud. Los objetivos, conflictivos entre si, existentes en instituciones de salud, necesitan un trato especial. El enfoque de MCDM es esencial para identificar requisitos y trascendencia de la calidad de servicio (QoS) en un sistema de TIC. Un estudio empírico basado en la opinión del usuario involucrando tres categorías de hospitales en Chile se lleva a cabo, considerando datos de varios representantes del sector de la salud. La contribución principal es la metodología propuesta para desarrollar criterios para valorar aplicaciones de QoS en una red de TIC de un servicio de salud a través del Proceso de Jerárquico Analítico (PJA). Los resultados proporcionan un marco para tomar decisiones referentes a un sistema de tecnología de la información, caracterizando usuarios, sus necesidades y permitiendo compensaciones de común acuerdo con los objetivos de la institución.

Palabras Claves: AHP, PJA, Decisiones multicriterio, TIC en servicio de salud.
