Development of Hypertension Management Mobile Application based on Clinical Practice Guidelines.

This study aims to develop and evaluate a mobile application for hypertension management based on Clinical Practice Guidelines. The application was developed according to Web-Roadmap methodology. In planning phase, we defined the tasks and product of each phase, selected clinical practice guidelines and extracted intervention items for hypertension management. In analysis phase, we analysed intervention items and made data dictionary, rules, use-case diagram, hypertension management ontology and tailored recommendations for the application. In design phase, we developed an entity-relations diagram, algorithm, and user interface and coded them in the implementation phase. In evaluation phase, first, the knowledge-base was evaluated for its accuracy by experts and they proposed three more detailed recommendations, which were added to the application. Second, mobile heuristics were evaluated. The evaluators pointed out 33 usability-related problems on mobile heuristics items. Out of these, three problems were solved by reflecting evaluators' comments.
