What is known and objective: The dispensing of clotting factor concentrates in hospital pharmacies imposes accessibility constraints on patients and their caregivers, thereby increasing the disease burden. Very few studies have addressed these issues so far in terms of individual perceptions and actual difficulties. The PHAREO study aims to report patient's perception of treatment accessibility and evaluate spatial accessibility. Methods: The PHAREO study is an observational survey based on a questionnaire specifically designed for the study purpose in collaboration with patients' representatives in the second demographic and economic French region. Results and discussion: We collected 293 responses (participation rate of 64.1%) which show that 89.8% of respondents were either very or rather satisfied with regard to access to treatment. However, respondents reported difficulties in accessing the hospital pharmacy. The data also showed that 79.2% of respondents tended to over-estimate travel time which was reported above their acceptable threshold for 39.2% of them. The main determinants of dissatisfaction were parental burden (OR 2.5 [1.3; 4.8], p = 0.008) and waiting time at the hospital pharmacy (OR 1.5 [1.1;2.0], p = 0.016, per 10 min increase). What is new and conclusion: The PHAREO study provides subjective and objective data regarding satisfaction levels of persons with haemophilia and other coagulation deficiencies, with a high representativeness rate for patients on prophylaxis (87.5%). Both respondents and hospital pharmacists pled for an evolution of the current dispensing circuit to improve access to treatment and reduce the burden for patients. Currently, the community pharmacists are apart from the dispensing circuit. The authors propose improvements in the pathway of care for patients and their caregivers by including the community pharmacists alongside the hospital pharmacists in a centralized coordination scheme.
