Healthcare Technology Assessment for Radiology Devices

Abstract

Health Technology Assessment (HTA) approaches are increasingly widely used in healthcare decision-making. HTA in medical devices remains a serious difficulty today, despite its extensive usage in medications and surgery. Because of scarce resources and rapidly rising healthcare costs, it is now necessary to assess the efficacy, appropriateness, and costs of health technologies such as drugs, biologics, devices, equipment and supplies, medical and surgical procedures, support systems, and organizational and managerial systems. The main goal of studying HTA devices is not to improve the cost-effectiveness ratio but to make decisions about purchasing and/or incorporating the device. Another significant goal is to extend the lifetime of the device. This study proposes a program to assist a clinical engineer in assessing a large variety of radiological devices (Ultrasound, x-Ray, Mammography, Digital Radiography (DR), and Computed Radiology (CR) using various Multi-Criteria Decision Making (MCDM) Methods. MCDM is now one of the best tools for evaluating medical equipment. This paper employed multiple MCDM methods, including the Evaluation Based on Distance from Average Solution (EDAS) method, Multi-objective Optimization based on Ratio Analysis (MOORA) method, The Technique for Order of Preference by Similarity Ideal Solution (TOPSIS) method, and Simple Additive Weighting (SAW) method. After experimenting with them, we discovered that the EDAS technique yields the greatest results in terms of device effectiveness. Using the various MCDM approaches, we were able to obtain the effectiveness and cost-effectiveness values needed to conduct HTA, which means we could assess 250 different devices from the four modalities in various locations.
