At CSL, we believe improving patient outcomes starts with listening, learning and working together. During a recent field visit to Morocco with the World Federation of Hemophilia / Fédération mondiale de l'hémophilie (WFH) Humanitarian Aid Program, Dirk Hoheisel, SVP and Head CSL International, joined colleagues and partners on the ground to engage directly with patients, clinicians and local patient organisations. These conversations provided valuable insights into both the progress being made – and the work still ahead – to improve care for people living with bleeding disorders. The visit reinforced a clear perspective: humanitarian aid plays a critical role, but its greatest impact lies in what it enables. By combining access to treatment with education, advocacy and system strengthening, partnerships like the WFH program help countries move towards sustainable, nationally supported care. As one of the long-standing partners to WFH, we remain committed to contributing to this progress – supporting immediate patient needs while helping build the foundations for long-term solutions. We would also like to recognise Sujan Sivasubramaniyam, our Global Head of Patient Advocacy, whose leadership helps ensure patient perspectives remain at the centre of our approach. Together with our partners, we will continue working towards a future where access to care is equitable, sustainable and available to all who need it. #PatientAdvocacy #AccessToCare #Partnerships
