Background/Purpose: Screening for pulmonary arterial hypertension (PAH) in systemic sclerosis (SSc) improves outcome. The DETECT screening algorithm (DETECT-algorithm) is recommended in a high-risk SSc subgroup. The aim of this study is to compare the positive predictive value (PPV) of screening using the 2009 European Society of Cardiology/European Respiratory Society guidelines (ESC/ERS-guidelines) and the DETECT-algorithm and comparing their cost-effectiveness in an unselected day-to-day SSc population.

Methods: 195 consecutive SSc patients, included in the Ghent University hospital systemic sclerosis unit, having their yearly SSc-specific visit between February 2015 and February 2016 were prospectively screened using both algorithms and the cost-effectiveness was calculated.

Results: In 63 (32%) of the 195 included patients (11%/71%/18% limited/limited cutaneous/diffuse cutaneous SSc), a right heart catheterization (RHC) was recommended (46/4/13 using DETECT-algorithm alone/ESC/ERS-guidelines alone/both algorithms). A RHC was performed in 53 patients: (36 [78%]/4 [100%]/13 [100%] where recommended by DETECT-algorithm alone/ESC/ERS-guidelines alone/both). PAH was diagnosed in 3 patients (incidence 1.5%/year, 95%CI:0.5-4.4%), in whom both algorithms recommended a RHC. The PPV was 23%,95%CI:8-50% (3/13) for both algorithms, 18%,95%CI:6-41% (3/17) for the ESC/ERS-guidelines and 6%,95%CI:2-17% (3/49) for the DETECT-algorithm. The average cost for screening was 80 and 227 euro using the ESC/ERS-guidelines and the DETECT-algorithm respectively.

Conclusion: In an unselected SSc population, the PPV is 23% when both algorithms recommend RHC. Interestingly, with only one algorithm used, the PPV drops to 18% for the ESC/ERS-guidelines and 6% for the DETECT-algorithm. Based upon this comparison and on cost-effectiveness, echocardiography may remain an important first step screening tool for PAH in SSc.
