Hypertension – coined a “silent killer” because there are no symptoms – is one of the most challenging healthcare burden globally. Around 27% of Hong Kong’s population have high blood pressure. Early detection and good blood pressure management can reduce the incidence of hypertension. However, there is a lack of awareness on the importance of regular blood pressure measurement, especially in young and middle-aged adults. Though international guidelines support home blood pressure as a reliable reference in the clinical approach, most doctors find it hard to accurately diagnose hypertension due to unclear handwriting and difficulties in calculating the average. Both trends and blood pressure variability, therefore, cannot be visualised for doctors and patients alike.
To promote digital self-management of blood pressure, the team developed a mobile app to capture blood pressure records directly from any model of blood pressure device with the smart phone camera. Users would see real-time analyses of their blood pressure profiles, especially the trend and variability, based on which personalised health care for better monitoring are provided, on top of predictions to guide treatment and improved clinical decision-making.
In addition, through educational talks at schools and NGO centres delivered by professionals and volunteers trained by the team, the public is offered knowledge and tips on blood pressure management.
Participants and healthcare professionals increase their awareness on the importance of blood pressure screening and regular monitoring. The latest technologies for self-blood pressure management will be introduced to achieve widespread use through educational talks, by promoting the acceptance of digital tools as a cost-effective means for early detection and monitoring.
– 4,000 public members aged 18 or above
– 700 participants for hidden pre-hypertensive screening
– 60 trainers (including students, social workers and retired elderly volunteers)
