  "abstract": "Introduction Commuting poses a considerable burden and costs for patients with rare rheumatic diseases such as systemic sclerosis (SSc), who require care from tertiary medical centres. In a universal healthcare system, the selection of healthcare services is possibly influenced by geographical distribution, referral networks from primary care, and patient preferences. This study aims to evaluate whether longer commuting distances are associated with clinical variables and differences in medication access among Italian SSc patients receiving follow-up care at tertiary centres.Material and Methods The driving distance from the city of residence to the care centre was calculated using the Google Maps Distance Matrix API for anonymized patients with SSc from the Systemic Sclerosis Progression INvestiGation (SPRING) Italian registry. This distance was then correlated with clinical and drug history in an ordinal logistic regression analysis.Results The characteristics of 1,782 patients were obtained from 38 centres across the country ( figure 1 and table 1): 74.2% were categorized as short-distance commuters (traveling less than 100 km), 20.1% as intermediate-distance commuters (traveling 100-500 km), and 5.6% as long-distance commuters (traveling more than 500 km). Notably, 24.6% of the patients received care outside their residential administrative region. Patients with interstitial lung disease (ILD), pulmonary arterial hypertension, lower Forced Vital Capacity (FVC), reduced Diffusion Capacity for Carbon Monoxide (DLCO), anti-Scl70 positivity, and anti-centromere negativity had higher probability of traveling longer distances. Similarly, access to multiple immunosuppressants (cyclophosphamide, azathioprine, methotrexate, tocilizumab) and vasoactive/vasodilator drugs (Endothelin Receptor Antagonists (ERA), Phosphodiesterase Type 5 Inhibitors (PDE5i), iloprost) was associated with increased probability of long travel distances (table 1). No significant differences were correlated to demographics or comorbidity burden.Conclusions SSc patients with pulmonary complications are more likely to undertake longer commuting distances and have a higher likelihood of receiving advanced treatments. Public health strategies should aim to enhance accessibility to specialized care and advanced therapies for these patients, recognizing the impact of travel burden on healthcare access.Abstract P.373 Figure 1Geographic distribution of tertiary Healthcare canters and residences of the enrolled systemic sclerosis patientsAbstract P.373 Table 1Patients characteristics and ordinal logistic regression analysis for short-, intermediate-, and long-commuting categories",
