Humanistic burden of haemophilia A without inhibitors: A cross-sectional analysis of the HemoLIFE study. Haemophilia 2024; 30:950-958. [PMID: 38825766 DOI: 10.1111/hae.15057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 04/02/2024] [Accepted: 04/03/2024] [Indexed: 06/04/2024]
Abstract
AIM To evaluate the impact of haemophilia A without inhibitors on humanistic outcomes in patients and caregivers. Herein, we report a cross-sectional analysis of the baseline data of persons with haemophilia (PWH) participating in the prospective study HEMOLIFE. METHODS These data are part of a prospective, observational, and multicentre study currently being conducted in 20 hospitals in Spain by haematologists. We included subjects 12 years or older diagnosed with haemophilia. The evaluations included the Maladjustment Scale, Haemophilia-Specific Quality of Life Questionnaire for Adults (HaemoQol)/HaemoQol Short Form (Children), haemophilia-specific version of the Work Productivity and Impairment Questionnaire plus the Classroom Impairment Questionnaire (WPAI+CIQ:HS), Haemophilia Activity List (HAL)/Paediatric Haemophilia Activities List (pedHAL), visual analogue scale (VAS) for evaluating pain, Coping Pain Questionnaire-Reduced (CAD-R), and Hospital Anxiety and Depression Scale (HADS). RESULTS A total of 81 PWH were recruited at 18 centres; 66 PWH were ≥18 years (i.e., adults), and PWH 15 were <18 years (i.e., paediatric patients). Out of the 79 evaluable subjects, 16 (20%) showed an impact of haemophilia on daily life, and the areas most affected were "leisure time" (58% showed maladjustment) and "work/studies" (47% showed maladjustment). Patients reported a higher impact of haemophilia on quality of life (mean [SD] of the transformed score) in the dimensions of "sport" (49.4 [28.6]), "physical health" (40.5 [25.8]) and "future" (37.7 [28.9]). In adults, according to HAL scores, greater impairment of function was observed in "lying/sitting/kneeling/standing," "function of legs" and "leisure activities and sports," with mean normalized scores of 64.7, 65.1 and 69.0, respectively. Productivity was mostly impacted by presenteeism. The pain was infrequent and moderate. According to the HADS scores, nine (11.5%) patients had clinical anxiety and depression. CONCLUSION PWH without inhibitors exhibited impairments in adjustment, quality of life and functionality, especially related to leisure and sports activities, and exhibit relevant levels of anxiety and depression.

Abstract
INTRODUCTION The PedHAL questionnaire is employed in measuring the activities of haemophilia children. The PedHALshort was developed in 2022 to determine the most relevant item for the assessment. Haemo-QoL questionnaire assesses the quality of life of haemophilia children. AIM Determine the validity and reliability of the PedHALshort Indonesia language version compared to the Haemo-QoL in the Indonesian population. METHODS A cross-sectional study was conducted in Jakarta, Indonesia. The subjects were children (4-16 years old) with moderate or severe haemophilia A or B with repeated joint bleeding. The daily activity was assessed using the PedHALshorts and Haemo-QoL. The validity and reliability were tested. The validity was determined with Pearson correlation test, construct validity was assessed using convergent and discriminant validity. The Spearman correlation was used to determine which domains of Haemo-QoL correlated with PedHALshort. The reliability was analyzed using test-retest reliability. Cronbach's α was used to determined internal consistency. RESULTS Fifty children were included in the study (78% haemophilia A, 70% severe group). All domains were valid (r > .284). The convergent validity test showed PedHALshort had a moderate negative correlation with physical health and sports school domain of Haemo-QoL (r = -.479, p < .001). The discriminant validity test showed the PedHALshort demonstrated a moderate negative correlation with physical health (r = -.585), view (r = -.590), sport school domain (r = -.430) in severe haemophilia subjects. The internal consistency of the PedHALshort questionnaire was high (Cronbach's α of .85 (.74-.92)). CONCLUSION The PedHALshort is valid and reliable, hence, it can be used to measure the functional physical activity of children with haemophilia.

Abstract
INTRODUCTION Recent recommendations of core outcome sets for haemophilia highlight the need for including measures of performance-based physical health and physical function sustainability. To date, there is no consensus on what outcomes might be of value to clinicians and patients. AIM To identify instruments of performance-based physical function to monitor musculoskeletal health in people with haemophilia that are practical in the clinical setting. METHODS Utilising components from the Activities and Participation Category of the WHO International Classification of Functioning (WHO-ICF), a consensus-based, decision analysis approach was used to: identify activities people with haemophilia have most difficulty performing; identify quantitative performance-based measures of identified activities via a scoping review; and obtain views on acceptability of the tests utilising a DELPHI approach. RESULTS Eleven activities were identified: maintaining a standing position, walking long distances, walking up and down stairs, walking on different surfaces, running, hopping, jumping, squatting, kneeling, undertaking a complex lower limb task, undertaking a complex upper limb task. Following a 2-round DELPHI survey of international physiotherapists, the 6-min walk test, timed up and down stairs, 30-s sit to stand, single leg stance, tandem stance, single hop for distance (children only) and timed up and go (adults only) reached consensus. CONCLUSION This study is the first step in defining a core set of performance-based instruments to monitor physical health and sustainability of physical function outcomes in people with haemophilia. Establishing the psychometric properties of the instruments and whether they are meaningful to people with haemophilia is essential.

Abstract
Background The use of patient-reported outcomes measures (PROMs) is important in hemophilia care, as it facilitates communication between patients and clinicians and promotes patient-centered care. Currently, a variety of PROMs with insufficient psychometric properties are used. Patient-reported outcomes measurement information system (PROMIS) measures, including Computer Adaptive Tests, were designed to measure generically and more efficiently and, therefore, are an alternative for the existing PROMs. Objectives To assess the feasibility, measurement properties, and outcomes of 8 PROMIS pediatric measures for boys with hemophilia. Methods In this multicenter study, boys with hemophilia completed 8 PROMIS measures and 2 legacy instruments. Feasibility was determined by the number of completed items and floor or ceiling effects (percentage of participants that achieved the lowest or highest possible score). Reliability was assessed as the percentage of scores with a SE ≤ 4.5. Construct validity was evaluated by comparing the PROMIS measures with the legacy instruments. Mean PROMIS T-scores were calculated and compared with the Dutch general population. Results In total, 77 boys with hemophilia participated. Reliability was good for almost all PROMIS measures and legacy instruments. The total number of completed items varied from 49 to 90 for the PROMIS pediatric measures, while the legacy instruments contained 117 to 130 items. Floor and ceiling effects were observed in both the PROMIS measures (0-39.5%) and legacy instruments (0-66.7%), but were higher for the legacy instruments. Conclusions The PROMIS pediatric measures are feasible to use for boys with hemophilia. With the use of the PROMIS measures in clinical care and research, a step toward worldwide standardization of PROM administration can be taken.

Abstract
INTRODUCTION The Haemophilia Activities List (HAL) and paediatric HAL assess self-reported limitations in various daily activities. To reduce patient burden, shorter versions of the pedHAL (22 items) and HAL (18 items) have been developed. AIM This study aimed to determine the agreement between the pedHAL/HALfull and pedHAL/HALshort and construct validity and internal consistency of the pedHAL/ HALshort in persons with haemophilia (PWH). METHODS A cross-sectional secondary analysis of the Hemophilia in the Netherlands-6 national survey was performed. Adult and paediatric PWH completed the original pedHAL/HALfull , from which pedHAL/ HALshort were derived. Score differences between the original and short versions were calculated. Construct validity was studied by testing hypotheses regarding the relationship of the pedHAL/HALshort with the pedHAL/HALfull , Haemophilia & Exercise Project Test-Questionnaire (HEP-Test-Q), Canadian Haemophilia Outcomes-Kids' Life Assessment Tool (CHO-KLAT) and RAND 36-item Health Survey (RAND-36) (convergent/discriminant validity) as well as its ability to discriminate between subgroups (known-group validity). Internal consistency was assessed with Cronbach's α. RESULTS We included 113 children (median 10y [range 4-17], 53% severe haemophilia) and 691 adults (median 51y [range 18-88], 35% severe). Scores of the pedHAL/HALfull and pedHAL/HALshort were similar with high correlations (>0.9). Construct validity was confirmed for the pedHAL/HALshort . The HALshort was able to discriminate between different disease severities and ages. Cronbach's α of the pedHAL/HALshort was 0.95-0.97. CONCLUSION This study confirmed the agreement between the pedHAL/HALfull and the pedHAL/HALshort and the construct validity of the pedHAL/HALshort . The next step is to study construct validity of the pedHAL/HALshort when administered as short forms.

Abstract
Hemophilia is a sex-linked recessive disorder characterized by a lack of blood factors necessary for clotting. This review aims to investigate the benefits of sports activities in children with hemophilia in terms of both physical and psychological wellness. Sports activity is necessary for children with hemophilia to preserve joints’ range of motion, reduce joint bleeding, improve muscle mass and strength, enhance proprioception and prevent secondary chronic diseases. In the past, high-impact sports were usually forbidden in children with hemophilia because of their high bleeding risk. Recent studies, however, have shown that prophylaxis therapy can allow a hemophilic child to take part in vigorous activities or high-impact sports. The benefits of sports activity in children with hemophilia are expressed by a better muscular trophism and an improved bone mineral density. Moreover, physical activity has a positive impact on children’s psychosocial well-being. Due to prophylaxis therapy, the quality of life of children with hemophilia is similar to their peers, and this has allowed an improvement in sports participation, including team sports.

Abstract
Introduction The paediatric Haemophilia Activities List (pedHAL) was developed to measure activities and participation in children and youth with haemophilia. Results from international studies provide an opportunity to determine which items are universally important. Aim The aim of this study was to determine which items of the pedHAL are redundant to construct a shorter version of the pedHAL. Methods This study is a cross‐sectional multicentre secondary analysis on pooled data of published studies using the pedHAL (7 domains, 53 items, optimum score: 100) in children with haemophilia A/B aged 4–18 years. To identify redundant items, the following aspects were evaluated: floor and ceiling effects, proportions of missing and ‘not applicable’ responses, inter‐item correlations, component loadings in an exploratory factor analysis, internal consistency and item‐total correlations. Results Data on 315 patients with haemophilia from 6 studies were evaluated. Median age was 12.2 years) (range 4.0–18.0), 87.3% had severe haemophilia and 80.3% received prophylaxis. Median (IQR) pedHAL sum score was 96.7 (88.0–100). After a stepwise procedure, 31 items were removed, resulting in a pedHALshort of 22 items, representing all original 7 domains. Most remaining items belonged to the domains ‘sitting/kneeling/standing’ and ‘functions of the legs’. The pedHALshort sum score was similar to the original pedHAL sum score, with small differences in 5 domains. Conclusion This clinimetric study resulted in >50% reduction of the length of the pedHAL. The 22‐item pedHALshort reduces patient burden and is expected to capture the information on activities and participation. The pedHALshort needs validation in other populations.

Abstract
Options for management of haemophilia are increasing rapidly with completely novel therapeutic approaches that cannot be compared using traditional factor assays. In addition, as prophylaxis regimens have improved, bleeding rates have decreased, and consequently, it is difficult to show an impact of novel therapies on rates of spontaneous bleeding. There is currently an urgent need for a panel of outcome measures to compare therapies that are dissimilar in many essential ways. Conventional objective outcome measures including joint physical examination and joint imaging continue to hold a central importance. Factor assays are essential for evaluation of products derived from native factor genes, but are not applicable to some extended half-life factors or non-factor bypassing agents. Global assays including thrombin generation and chromogenic assays of factor X activation are under investigation for their usefulness in haemophilia assessment. Bleeding rate is a conventional subjective patient-reported outcome that, while decreasing in frequency, is indispensable as an outcome given that the primary manifestation of haemophilia is bleeding. Other patient-reported outcomes such as pain intensity and interference, health-related quality of life and activities and participation are increasingly important to distinguish superior outcomes in comparative trials. This review of outcome measures for haemophilia presents examples of existing outcome measures with an emphasis on their strengths and limitations.

Abstract
INTRODUCTION The Paediatric Haemophilia Activities List (pedHAL) assesses self-reported limitations in activities and participation in children with haemophilia. AIM To assess longitudinal changes, child-parent agreement and to identify which pedHAL domains yielded most information in boys with access to early prophylaxis. METHODS The pedHAL (53 items, 7 domains, optimum 100) was completed annually at the Van Creveldkliniek by boys aged 4-18 years with moderate/severe haemophilia and their parents. Development of the pedHAL in relation to bleeds, changes per domain over 3-5 years, child-parent agreement (% difference child-parent≤|5|) per domain and domain scores (limitations defined as ≤ 95) were determined. RESULTS Seventy-three patients and their parents (92% severe haemophilia, median age 13.1 years [range 5.4;18.0]) completed ≥1 pedHAL. Median (IQR) pedHAL sum score was 99.5 (95.2;100.0) for children and 99.6 (95.8;100.0) for parents. If patients scored >95 and had no joint and/or muscle bleed, 90.9% of the patients scored >95 at the next assessment. The median change in sum score was 0.0 for both the 3- and 5-year interval. Child-parent agreement varied between domains from 92% ('self-care') to 71% ('sitting/kneeling/standing'). Most limitations were reported in the domains 'sitting/kneeling/standing', 'functions of the legs' and 'leisure activities and sports.' CONCLUSION In routine clinical practice in Dutch children on prophylaxis, pedHAL scores were high and remained stable in 3-5 years at group level. In individual patients without joint and/or muscle bleeds, pedHAL scores remained high after 1 year. Child-parent agreement was not optimal which indicated that both child report and parent proxy should be reported.
