Abstract
INTRODUCTION Hemophilia can detrimentally affect patients' quality of life and likelihood of survival. In the evolving landscape of therapies, the therapeutic gain of each treatment must be understood to accurately position it in the therapeutic armamentarium. Accordingly, appropriate outcomes must be measured with appropriate tools. AREAS COVERED Our narrative review (PubMed search for 'hemophilia AND outcome' until June 2023), provides a compendium of outcome measures used in hemophilia clinical research. To define each outcome measure's relative value and applicability, several characteristics are critically discussed. EXPERT OPINION Bleeding assessment, first annual/annualized bleeding rate, remains central in evaluating the efficacy and safety of hemophilia treatments. As modern therapies improve clinical outcomes toward zero bleeding events, this endpoint may become less sensitive to detect differences between therapeutic approaches. Technological advancements necessitate the adaptation of outcome measures to address infrequent bleeding events, age-related comorbidities, and laboratory parameters with limited comparability after different treatments. Considerable effort has been dedicated to the development of tools that comprehensively assess coagulation, such as thrombin generation assays. Patient-reported outcome measures are gaining importance although limited by their subjectivity. A definitive set of research outcome measures remains elusive. Outcomes may need to be tailored to different therapeutic interventions.

Abstract
BACKGROUND AND OBJECTIVES Haemophilia comprises a continuum of blood disorders that often include joint and muscular dysfunction, which may lead to a constellation of activity limitations and participation restrictions. However, there is scant research incorporating functional assessment scales into the common language provided by the International Classification of Functioning, Disability and Health (ICF). This study aims to identify the ICF categories to include in an item bank of functioning aspects relevant for haemophilia. DESIGN AND METHODS A systematic search was carried out in July 2021 based on the PubMed MEDLINE, CLINICAL, and Cochrane databases for qualified articles, investigating haemophilia-specific scales and the scales recommended by the World Federation of Haemophilia (WFH) linked to ICF categories between 2001 and 2021. Well-trained healthcare professionals in the haemophilia field and ICF evaluation conducted group discussions to determine the ICF items for haemophilia. RESULTS A total of 112 out of 176 items measuring function were collected for the haemophilia ICF item bank, including 32 items for body function (b), 45 items for activity and participation (d), 27 items for environmental factors (e), and 8 items for body structure(s). INTERPRETATION AND CONCLUSIONS We recommend that future haemophilia research use the haemophilia-specific ICF item bank, which could capture a whole spectrum of functional measurements and facilitate multidisciplinary and worldwide communication. This study also indicates that further development and analysis of the psychometric properties of the 112 haemophilia-related ICF items is warranted.

Abstract
BACKGROUND AND OBJECTIVES There is scant research investigating the user-friendly functional assessment tool conceptualized by the International Classification of Functioning, Disability and Health (ICF) among persons with haemophilia (PWH). This study aims to accomplish two goals: (1) quantifying comprehensive functioning measures of haemophilia through Item Response Theory (IRT); (2) discussing patient-centred care based on the Wright map of personal ability and item difficulty. METHODS A cross-sectional study was carried out in 70 PWH (mean age, 33.09 ± 11.04) via convenience sampling. All patients completed the 45 ICF categories of haemophilic-specific activity and participation. Psychometric properties of the categories were examined using Mokken scale analysis and parametric item response modelling. RESULTS We extracted a unidimensional scale with 31 categories, and constructed a Rasch model with good fitness. The Cronbach's α of the scale was .9713, with the Guttman's λ2 = .9730, Molenaar Sijtsma ρ = .9802, and latent class reliability coefficient = .9769, indicating great internal reliability. The estimated individual social competence by the Rasch model was highly related to the index score of the three-level EuroQol five-dimensional questionnaire (EQ-5D-3L) (p < .001, r = .62), and had a moderate correlation (p < .001, r = .54) with the score of Haemophilia Activities List (HAL). CONCLUSIONS The ICF scale of haemophilic activity and participation with 31 categories (HAPPY-ICF) has good construct validity and internal consistency. The person-item threshold distribution map might be helpful in research and clinical practices for patient-oriented care.

Abstract
Introduction For persons with hemophilia, optimization of joint outcomes is an important unmet need. The aim of this initiative was to determine use of ultrasound in evaluating arthropathy in persons with hemophilia, and to move toward consensus among hemophilia care providers regarding the preferred ultrasound protocols for global adaptation. Methods A global survey of hemophilia treatment centers was conducted that focused on understanding how and why ultrasound was being used and endeavored to move toward consensus definitions of both point‐of‐care musculoskeletal ultrasound (POC‐MSKUS) and full diagnostic ultrasound, terminology to describe structures being assessed by ultrasound, and how these assessments should be interpreted. Next, an in‐person meeting of an international group of hemophilia health care professionals and patient representatives was held, with the objective of achieving consensus regarding the acquisition and interpretation of POC‐MSKUS and full diagnostic ultrasound for use in the assessment of musculoskeletal (MSK) pathologies in persons with hemophilia. Results The recommendations were that clear definitions of the types of ultrasound examinations should be adopted and that a standardized ultrasound scoring/measurement system should be developed, tested, and implemented. The scoring/measurement system should be tiered to allow for a range of complexity yet maintain the ability for comparison across levels. Conclusion Ultrasound is an evolving technology increasingly used for the assessment of MSK outcomes in persons with hemophilia. As adoption increases globally for clinical care and research, it will become increasingly important to establish clear guidelines for image acquisition, interpretation, and reporting to ensure accuracy, consistency, and comparability across groups.

Abstract
The physiotherapist plays an essential role for people with haemophilia, an inherited bleeding disease responsible for musculoskeletal complications. Yet, with the advent of new and advanced therapies, the medical landscape is changing, and physiotherapy must adapt alongside. This paper considers whether there will still be a need for physiotherapy in the era of advanced therapies, and discusses ways in which services should evolve to complement emerging treatment paradigms for haemostasis in people with haemophilia. Ultimately, physiotherapy will remain an important element of care, even for people with little joint damage and low risks in the era of the new mild phenotype. However, competencies will need to evolve, and physiotherapists in both primary care and specialist treatment centres should work with haematology colleagues to develop more sensitive tools for detecting early joint changes. Physiotherapists will also play a crucial role in counselling and physically coaching, monitoring the musculoskeletal status of people with haemophilia who have transitioned to new treatments.

Abstract
INTRODUCTION A lack of uniformity in the choice of outcome measurement in hemophilia care and research has led to studies with incomparable results. We identified a need to define core outcome measures for use in research and clinical care of persons with hemophilia. OBJECTIVE To move toward a core set of outcome measures for the assessment of persons with hemophilia in research and practice. METHODS A modified nominal groups process was conducted with an international group of hemophilia experts, including persons with hemophilia as follows. Step 1: item generation for all potential outcome measures. Step 2: survey where respondents voted on the relative importance and usefulness of each item. Steps 3/4: 2-day meeting where attendees voted for items they valued, followed by open discussion and a second round of voting. Step 5: survey where respondents selected their top five items from those with >50% agreement at the meeting. RESULTS The highest ranked items for the pediatric core set (% agreement) are treatment satisfaction (92.7%), joint health (83.3%), a measure of access to treatment (82.5%), a measure of treatment adherence (72.5%), and generic performance based physical function (72.1%). The highest ranked items for the adult core set (% agreement) are total bleeding events (88.1%), EuroQol five dimensions (85.4%), treatment adherence (82.1%), joint health (79.1%), and number/location of bleeds per unit time (78.6%). CONCLUSION This process generated a list of preferred outcome measures to consider for assessment in persons with hemophilia. This information now requires refinement to define optimal core sets for use in different clinical/research contexts.

Abstract
INTRODUCTION Contemporary haemophilia care demands Patient-Reported Outcomes. SO-FIT is a UK multi-centre study, assessing self-reported function, health-related quality of life (HRQoL) and joint health in boys with severe haemophilia. METHODS Subjective physical function (PedHAL, HEP-Test-Q) and HRQoL (Haemo-QoL Short Form [SF]) were assessed alongside joint health using the objective Haemophilia Joint Health Score (HJHS v2.1). Demographic and clinical data were collected. RESULTS Data from 127 boys mean age 12.38 ± 2.5 (range 8-17) treated at 16 sites were analysed. One-hundred-and-thirteen had haemophilia A, 25/9 past/current inhibitor, 124 were treated prophylactically (46.8% primary) and three on-demand. In the preceding 6 months, boys reported median 0 joint bleeds (range 0-8) with a median HJHS score of 1 (range 0-30). Boys reported good physical functioning; HEP-Test-Q (M = 80.32 ± 16.1) showed the highest impairments in the domain "endurance" (72.53 ± 19.1), in PedHAL (M = 85.44 ± 18.9) highest impairments were in the domains "leisure activities & sports" (M = 82.43 ± 23.4) and "lying/sitting/kneeling/standing" (M = 83.22 ± 20.3). Boys reported generally good HRQoL in Haemo-QoL SF SF (M = 22.81 ± 15.0) with highest impairments in the domains "friends" (M = 28.81 ± 30.5) and "sports & school" (M = 26.14 ± 25.1). HJHS revealed low correlations with the Haemo-QoL SF (r = .251, P < .006), the PedHAL (r = -.397, P < .0001) and the HEP-Test-Q (r = -.323, P < .0001). A moderate correlation was seen between HEP-Test-Q and Haemo-QoL SF of r = -.575 (P < .0001) and between PedHAL and Haemo-QoL SFr = -.561 (P < .0001) implying that good perceived physical function is related to good HRQoL. CONCLUSIONS The SO-FIT study has demonstrated that children with severe haemophilia in the UK report good HRQoL and have good joint health as reflected in low HJHS scores.
