Case study from Innovation: early diagnosis in community settings

An app could identify heart failure in people with frailty, Hong Kong

8 December, 2022

What is the aim?

There is an ongoing study on the use of an app to detect undiagnosed heart failure in people with frailty.1 It was based on studies showing a high prevalence of heart failure in people with frailty in community settings – 33.5% had heart failure, mostly heart failure with preserved ejection fraction (HFpEF).2 3

What has been achieved?

The study is recruiting more than 4,000 individuals with frailty who have been discharged from hospitals within a regional hospital cluster network.1 Following a questionnaire to identify heart failure, diagnosis will be confirmed using natriuretic peptide testing and echocardiography.
