Abstract

Objective: The purpose of this study was to verify the algorithm on bio-signals for a home-health management system.

Methods: A methodological study was done to verify the blood pressure and blood sugar algorithm to deliver tailored patient information. The verifying process was as follows: Step 1; development of the algorithm through a literature review, Step 2; programming the algorithm using Microsoft SQL Server 2005 and Visual Studio 2005, Step 3; Reviewing of the algorithm by examining results from the home-health management system and experts' evaluation Step 4; evaluating the agreement of the algorithm by comparison between results from the home-health management system and intended results using bio-signal data set, and completion of the algorithm.

Results: Discordance rate between results from the home-health management system and intended results for blood pressure and blood sugar were 5.72% and 2.04%, respectively. Also, discordance rate between results from the home-health management system and experts' evaluation of blood pressure and blood sugar were 30.38% and 20.41%, respectively. All discordance were revised until all the researchers reached agreement.

Conclusion: The home-health management system with an accurate algorithm on bio-signals can contribute to promote clients' health and reduce the cost of medical services.

Key Words: Bio-signal Data, Algorithm, Telehealth (Home-health Management System)
