This project presents the result of a new proposal to improve telemonitoring and self-management for heart failure patients: The Health Dashboard. The Health Dashboard is designed for Philips in collaboration with the Reinier the Graaf hospital in Delft. It aims to reduce the chance on readmissions, to reassure heart failure patients about their health, to increase adherence in daily monitoring and to provide reliable insights about patient’s health to the medical team. It is used in the bathroom of the patient and is provided during the 30 days after a hospital admission. An integrated design process is executed from a strategic start towards a feasibility study in the end. Exploring opportunities. Studies towards the effect of telemonitoring show many contradictions, however well implemented with a multi-pronged approach it can have positive influences on reducing readmissions and improving quality of life. Literature is analysed to define strengths and weaknesses of telemonitoring systems and compared with promising health care trends. Two search areas are chosen to focus on: (1)“Enriching measurements with context information to reduce false alarms” and (2)“Tailoring telemonitoring systems to individual preferences to improve adherence and to reassure patients” Discover Three researchers are performed to gain insights in patient profiles, communication between stakeholders and increasing monitoring adherence. Patient profiles: the project combines the patient profiles defined by Philips with the insights model. This resulted in four profiles: Analyst (involved in treatment and relies on doctors advice), Fighter (involved in treatment and follows own path), Sensitive (passive in treatment and relies on doctors advice) and Optimist (passive in treatment and follows own path). Communication between stakeholders: The medical team wants to have insights in the amount of fluid retention from the patient. Therefore the patient needs to weigh himself every morning and watch for symptoms such as breathlessness. Increasing adherence: The behaviour change theory from Jonathan Haidt about the rider, elephant and environment is used to improve adherence in monitoring behaviour. Next reminders are provided according the Fogg model that describes that motivation and ability should be increased to let these reminders succeed. The content of these reminders is based on the six persuasive techniques from Cialdini: Authority, Consensus, Consistency and commitment, Scarcity, Liking and Reciprocity. Define & Develop After a comprehensive ideation and conceptualisation phase, the Health Dashboard has been developed. It has four main functions: (1) Prepare (increasing motivation and ability), (2) Trigger (Providing reminders with the right content on the right time) , (3) Measure (measuring weight and respiration rate with use of a weight scale and bed sensor) and (4) Feedback (reassuring patients and adding context information to measurements). Design The Health Dashboard tailors its behaviour towards individual patients with use of both explicit and implicit profiling. It can be described by its main functions: 1. Prepare: An external application increases motivation by providing education and the ability to set own goals. The health dashboard itself increases motivation by providing rewards after measurements. 2. Trigger: A passive motion sensor detects when the patient enters the bathroom. The Health Dashboard illuminates with a blue colour and shows, depending on patients adherence and patient profile, a message based on the principles of Cialdini. 3. Measure: The system of Health Dashboard contains a connected bed sensor and weight scale. These measurements are used to define a health score that ranges from 1 to 5. A health-score 5 means that all measurements are stable. Patients can add context information to measurements by answering questions on the device. 4. Reassure: The Health Dashboard reassures patients in a tailored way, and illuminates in a green colour if the health status is stable. Patients with a fighter profile will only see the green colour whereas patient with a sensitive profile will see a reassuring message. The hypothesis is that patients will be reassured more by showing a health score instead of rough measurement data, which will result in a lower chance on readmissions and better quality of life. This project can be a start of further research towards a new innovative approach in telemonitoring cardiac patients.
