RT Journal Article SR Electronic T1 Differing commissioning arrangements may contribute to geographic variation in clinical management of digital ulcers in systemic sclerosis JF Clinical Medicine JO Clin Med FD Royal College of Physicians SP 343 OP 345 DO 10.7861/clinmed.2020-0031 VO 20 IS 3 A1 Elizabeth Reilly A1 Randa Alshakh A1 Celia Beynon A1 Matthew Cates A1 Dhivya Das A1 Shuja Majeed A1 Ahsan Memon A1 Patrick O’Beirn A1 James Ritchie A1 John D Pauling YR 2020 UL http://www.rcpjournals.org/content/20/3/343.abstract AB Phosphodiesterase inhibitors (such as sildenafil) and endothelin receptor antagonist, bosentan, are effective for digital ulcer disease in systemic sclerosis (SSc-DU) and are endorsed in international treatment recommendations. Commissioning of high-cost drugs, such as bosentan, however, differs across devolved nations of the UK. We report a multicentre service evaluation project to examine ‘real world’ management of SSc-DU before and following the 2015 UK Scleroderma Study Group (UKSSG) guidance, across south-west (SW) England and Wales. Results showed that iloprost and sildenafil use for SSc-DU was higher in patients in Wales prior to 2015. Between 2015–2017, sildenafil use for SSc-DU increased in SW England while remaining stable in Wales. Bosentan use for SSc-DU after 2015 in SW England increased, while remaining stable and proportionately lower in Wales. These findings demonstrate that differing commissioning guidance across devolved nations of the UK seems to contribute to geographic variation in patient care.
