INTRODUCTION: People with haemophilia suffer from haemophilic joint disease that may result in physical inactivity and overweight. Shared medical appointments (SMAs) might help limit the consequences of haemophilic arthropathy. SMAs are group meetings supervised by one or more healthcare professionals that can be utilized to improve lifestyle. AIM: To evaluate the feasibility and efficacy of SMAs in people with haemophilia to improve physical activity and eating habits. METHODS: A multiple baseline single-case design was used. Overweight people with haemophilia were eligible to participate. Seven weekly SMAs were conducted using multiple behavioural change techniques to improve physical activity and eating habits. Feasibility of SMAs was evaluated using (a) dropout rate, (b) occurrence of adverse events (AEs), (c) adherence rate and (d) patient satisfaction. During 13 weeks, physical activity was measured daily and eating habits were measured three times per week. The efficacy of SMAs was determined using randomization tests and visual data inspection. RESULTS: Out of the six men participating in the study, one participant dropped out. No study-related AEs occurred. The adherence rate of SMAs was 80%, and participants reported to be 'very satisfied' with the SMAs. Randomization tests and visual analyses demonstrated (statistical) improvements in physical activity (p = .03). No effect was found in self-reported eating habits (p = .55). CONCLUSION: Shared medical appointments are feasible in people with haemophilia and appear to improve physical activity. The effect on improving eating habits could not be established. Scientific replication of our approach is warranted to confirm or refute the merit of SMAs in people with haemophilia.
