Problem: A Major challenge for healthcare providers is the non-adherence of patients to prescrip- tions. One important area is hypertension treatment through medication. A treatment often starts with multiple adjustment cycles of medication type or dosage, which are based on regular at-home blood pressure measurements. Patients therefore need to adhere to regular medication intake and blood pressure measurements. Research Aim: The project first explored whether or not it is possible to develop a medication reminder system that checks patient adherence based on vital parameters. The project goal was adapted to the design and development of a reminder and data logging system for hypertension patients, based on the following research questions: 1) What are functional and non- functional requirements for the proposed artefact? 2) How can these requirements be implemented? Method: The project makes use of Design Science Research to create the system. The problem and requirement explication for the new artefact was achieved by working closely with a general prac- titioner who deals with hypertension patients. The artefact was evaluated by presenting it ex-post to a focus group of a hypertension patient, developers and founders in digital health. Results: The results of expert interviews concluded that the initial project aim is not feasible due to continuous vital monitoring being invasive and intrusive, lack of applicability for health conditions and medica- tions and other potential negative consequences. These insights led to the new research aim. The results address the question: ”What are functional and non-functional requirements for the proposed artefact?”. The envisioned product is a cross-platform application, illustrating the frequent medica- tion adjustments for hypertension patients. The treating doctor should configure all patient-specific parameters and the app should guide patients through daily tasks like measurements and medication intake. The patient should also be reminded of their tasks. The app should record, display, and export data for the doctor’s review, and ensure easy input of measurements. Future remote data exchange capabilities via servers were also considered. To address the research question ”How can these requirements be implemented?”, the researcher developed a cross-platform mobile application for iOS and Android with .NET Multi-Platform App UI (MAUI) that implements the desired features. A concept for remote data exchange and a system for scanning measured values of blood pressure devices were developed. The evaluation partially validated the problem area and discussed future implementations, such as remote data exchange, usage of patient data for research and adoption to other medication. The perceived high usability of the application was emphasized. Conclusions: The researcher concludes that the developed artefact addresses a relevant problem and extends existing solutions in the problem space. It is acknowledged that future research has to be conducted to prove the effectiveness of the tool as well as assess its usability and accuracy. Difficulties for accepting the artefact in real life settings are discussed.
