Rheumatic heart disease represents the greatest cardiovascular inequality between Indigenous and non-Indigenous Australians. From 2013 to 2017, 94% of all new rheumatic heart disease cases were among Aboriginal and Torres Strait Islander people. This app assists clinicians in the diagnosis and management of acute rheumatic fever and rheumatic heart disease. Published by RHDAustralia, based at Menzies School of Health Research, the app contains the most up-to-date evidence and details various aspects of patient care. It is informed by the 2020 Australian guideline for prevention, diagnosis and management of acute rheumatic fever and rheumatic heart disease (3rd edition), available at https://www.rhdaustralia.org.au/arf-rhd-guideline. The app also contains an ARF Diagnosis Calculator which embeds the lengthy and complex ARF diagnosis algorithms into a series of simple questions that assist clinicians to diagnose ARF. The algorithms comply with the 2015 American Heart Association revision of the Jones Criteria for diagnosis of ARF, which has been endorsed by the World Heart Federation, making the Diagnosis Calculator now able to be used globally.

Verdict

The call

The clearest difference is price: ARF RHD Guidelines at Free against DrugDoses's $14.99. ARF RHD Guidelines also leads on review sentiment (100% vs 64%) and in-app purchases (none vs 4). DrugDoses's advantage is ratings volume (37 vs 1) and chart position (#184 vs unranked). On update cadence, ads, device support and iOS requirement there is nothing between them.
