AI task-shifting for echocardiographic left ventricular ejection fraction (LVEF) assessment in Singapore: an economic evaluation
- cost-minimization analysis
- decision tree model
- probabilistic sensitivity analysis
Authors' conclusion
This study provides economic evidence that task-shifting echocardiographic assessment of LVEF to novices using AI-POC devices is likely cost-saving compared to standard TTE. This task-shifting strategy offers a cost-saving alternative to conventional sonographer-led TTE.
Study context
- Population
- Patients with suspected heart failure undergoing assessment for LVEF <50%, single tertiary referral centre in Singapore
- Comparison
- AI-POC vs TTE
