AB  - Screening for pulmonary arterial hypertension (PAH) in systemic sclerosis (SSc) improves outcomes. The DETECT screening algorithm is recommended in a high-risk SSc subgroup. This study aims to compare prospectively the positive predictive value of screening using the DETECT algorithm and the 2009 European Society of Cardiology/European Respiratory Society (ESC/ERS) guidelines, and to compare their cost-effectiveness in an unselected, day-to-day SSc population. Post hoc, screening according to the 2015 ESC/ERS guidelines using echocardiographic parameters alone (“2015 echo screening”) or combined with the DETECT algorithm (“2015 combined screening”) in high-risk subjects was analysed.195 consecutive SSc patients included in the Ghent University Hospital SSc cohort were screened using different algorithms.The referral rate for right heart catheterisation was 32% (63 out of 195 patients) (46/4/13/34/40 patients using the DETECT algorithm/2009 guidelines/both/2015 echo screening/2015 combined screening). Right heart catheterisation was performed in 53 patients (84%) (36 (78%)/four (100%)/13 (100%)/28 (82%)/32 (80%) patients recommended by the DETECT algorithm/2009 guidelines/both/2015 echo screening/2015 combined screening). PAH was diagnosed in three patients (incidence 1.5%·year–1, 95% CI 0.5–4.4), in whom all algorithms recommended a right heart catheterisation. The positive predictive value was 6% (95% CI 2–17%; three out of 49 patients) for the DETECT algorithm, 18% (95% CI 6–41%; three out of 17 patients) for the 2009 guidelines, 23% (95% CI 8–50%; three out of 13 patients) for both, 11% (95% CI 4–27%; three out of 28 patients) for the 2015 echo screening and 9% (95% CI 3–24%; three out of 32 patients) for the 2015 combined screening. The cost was EUR224/80/90/112 per patient using the DETECT algorithm/2009 guidelines/2015 echo screening/2015 combined screening.Echocardiography may remain a candidate first step for PAH screening in SSc.Echocardiography remains a candidate first step in screening for PAH in an unselected systemic sclerosis population http://ow.ly/nuoh3096nRh
