Pulmonary vascular disease & thromboembolism
Novel automated electronic medical record-based virtual echocardiography screening tool (VEST) (virtual echocardiography screening tool) algorithm for pulmonary arterial hypertension
Authors' conclusion
This novel EMR-based automated VEST calculator is a powerful yet simple scoring tool that can capture patients at high risk for PAH, prompting earlier diagnosis and referrals to accredited PH centers to allow for earlier expert care and implementation of medical therapies.
Study context
- Population
- Patients who underwent transthoracic echocardiogram (TTE) with tricuspid regurgitation velocity (TRV) ≥2.9 m/s in a hospital with an accredited pulmonary hypertension (PH) Center of Comprehensive Carepatients who underwent TTE with TRV ≥2.9 m/s
- Participants
- 4,952 patients
- Exposure
- Electronic medical record (EMR)-calculated VEST scores compared to manually calculated VEST scores
- +3 scoren = 354
- Never referred for specialty PH caren = 104
- Referred to subspecialty PH caren = 250
- Outcome
- Validation of automated EMR VEST scores against manual scores
Main finding
As reported in the abstract
Correlation to 60 manual scores
100%
Observational data: associations, not effects.
Further findings
| Outcome | Never referred for specialty PH care | Referred to subspecialty PH care |
|---|---|---|
| Referral and RHC among +3 score patients | 29.4% | |
| Underwent RHC (of these 104) | 37.5% | — not stated in the abstract |
| Underwent RHC (of these 250) | — not stated in the abstract | 237 (94.8%) |
— not stated in the abstract
Hemodynamics in +3 score patients who underwent right heart catheterization (RHC)
- Mean pulmonary artery pressure
- 48 mm Hg
- Pulmonary vascular resistance
- 8.5 Wood units
- Of 354 patients with +3 score, those that underwent RHC
