Abstract
Understanding user needs is essential for Health Technologies Assessment (HTA) of medical devices, especially in early stage. Few studies propose analytic quantitative methods to elicit user needs, and among those a method that seems to be particularly effective to elicit user need was the Analytic Hierarchy Process (AHP). This paper describes the AHP method for User need Elicitation of Medical Devices and present a distribute web system to support its applications.
The aim of this study was to compare the two methods to estimate the ApEn proposed by other researchers for selecting threshold values in normal subject and in patients suffering from congestive heart failure. Thus, 19459 stationary HRV time series, extracted from electrocardiographic public databases, were analyzed. We computed the values of r threshold and the corresponding ApEn estimates using both the methods and the differences between the two estimated were assessed by a non-parametric test.
Our analysis showed that the two methods provided significantly different (p<0.001) values. For that reason, we recommend that ApEn, in particular the estimation obtained with the formula given by Chon et al., should be used with caution since different threshold values r could affect the analysis and provide incorrect conclusions. Future works may propose more reliable methods to estimate ApEn with lower computational cost, that could be feasible also for real time processing in telemedicine services.
