Introduction: Gaps in the disease knowledge of People with Haemophilia (PWH) in Senegal are important barriers to the effective management of haemophilia. Digital health systems for chronic diseases in low‐ and middle‐income countries are suggested to improve education and self‐management. Artificial Intelligence (AI) chatbots could improve knowledge and support symptom monitoring. Aim: Development process and usability testing of an AI chatbot to assess its future adoption in Senegal. Methods: An AI chatbot prototype was designed based on a multilingual conversational engine using Natural Language Processing. A sequential mixed method was used including a co‐creative design process with a task force made up of PWH and medical doctors. Usability was assessed through the System Usability Scale (SUS) questionnaire. Results: An AI chatbot in French and Wolof, named Saytù Hemophilie, was developed for Android and Apple iOS devices. It was assessed as a very usable system with a SUS score of 81.7, above average. 42% would prefer to use the Wolof version even if they were very satisfied with the French version. The level of Wolof in the app did not always correspond to users' levels. Participants praised its accessibility and reliability, and its ability to enhance self‐learning. Conclusions: Findings suggest that a culturally adapted digital conversational agent is likely to be used by PWH in Senegal and their families to improve education and self‐management of haemophilia. Relevance and impact are foreseen for other communities in Africa and beyond. [ABSTRACT FROM AUTHOR]

Introduction: In many sub‐Saharan countries, haemophilia exists in an environment of poor knowledge and poor access to treatment. To improve the quality of life of Persons with Haemophilia (PWH), understanding their unmet needs and the socio‐cultural realities is essential. Aim: This study aims to explore disease knowledge, beliefs, behaviours and concerns of PWH and carriers as a way to find adapted solutions to address the unmet needs. Methods: Based on an interview guide, we performed a qualitative study with in‐depth interviews of 26 PWH and 14 carriers. Results: Eighty per cent of adult PWH were able to name the severity of haemophilia, but only 32% could describe with accuracy the mode of transmission of haemophilia. Only 23% of carriers were able to inform the severity of the disease. All carriers and adult PWH acknowledged at least one visit to a traditional healer. Acceptance of the disease through religion is the dominant coping strategy observed. High costs of treatment, fear of social rejection, difficulty of management of pain and bleeding at home were the main concerns. Conclusions: Results demonstrate important gaps in knowledge, especially within the carrier population, mothers in Africa playing particularly an important role in the survival and empowerment of PWH. Findings also indicate the important weight of cultural determinants in disease management and behaviours of PWH and thus their important role in the development of educational materials taking into account these determinants.
