An ad hoc questionnaire was developed and sent to 586 patients/caregivers with haemophilia A, haemophilia B and VWD type III. The survey included information on demographic and clinical data, needs, concerns and experiences regarding medical care during COVID-19 pandemic. Results: In total, 355 of the IBD-Group (200 patients, 155 caregivers) completed the survey (61.7% response rate). Most patients suffered from haemophilia A (73.8%) and were severely affected (64.7%). Eleven patients were in quarantine due to suspected COVID-19; none had symptoms. One quarter worried (very) strongly about getting the coronavirus, 71.3% asked themselves what will happen to them when they will get COVID-19, 40.1% felt unchanged, and 18.9% worried about delivery difficulties of their IBD treatment product. In 52.8%, medical appointments were postponed. Significant differences between caregivers and patients were found in most aspects. Discussion: The IBD patients affected by a chronic disorder have particular thoughts and worries regarding COVID-19. Haemophilia specialists should be committed to address these concerns and guarantee treatment despite containment strategies.
