RESUMO
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.
RESUMO
BACKGROUND: Regular physiotherapy with a physiotherapist experienced in the field is not feasible for many patients with haemophilia. We, therefore, developed a blended physiotherapy intervention for persons with haemophilic arthropathy (HA) (e-Exercise HA), integrating face-to-face physiotherapy with a smartphone application. AIM: The aim of the study was to determine proof of concept of e- Exercise HA and to evaluate feasibility. METHODS: Proof of concept was evaluated by a single-case multiple baseline design. Physical activity (PA) was measured with an accelerometer during a baseline, intervention and post-intervention phase and analysed using visual inspection and a single case randomisation test. Changes in limitations in activities (Haemophilia Activities List [HAL]) and a General Perceived Effect (GPE) were evaluated between baseline (T0), post-intervention (T1) and 3 months post-intervention (T2) using Wilcoxson signed rank test. Feasibility was evaluated by the number of adverse events, attended sessions and open-ended questions. RESULTS: Nine patients with HA (90% severe, median age 57.5 (quartiles 50.5-63.3) and median HJHS 32 (quartiles 22-36)) were included. PA increased in two patients. HAL increased mean 15 (SD 9) points (p = .001) at T1, and decrease to mean +8 points (SD 7) (p = .012) at T2 compared to T0. At T1 and T2 8/9 participants scored a GPE > 3. Median 5 (range 4-7) face-to-face sessions were attended and a median 8 out of 12 information modules were viewed. No intervention-related bleeds were reported. CONCLUSION: A blended physiotherapy intervention is feasible for persons with HA and the first indication of the effectiveness of the intervention in decreasing limitations in activities was observed.

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.

BACKGROUND: Legacy hemophilia-specific questionnaires are considered too long, show floor-/ceiling effects, and/or include irrelevant questions. Patient Reported Outcomes Measurement Information System (PROMIS) item banks, including Computer Adaptive Tests (CATs) and short forms, were designed for more efficient outcome assessment. OBJECTIVES: Evaluate the feasibility, measurement properties, and relevance of seven PROMIS CATs and two short forms in patients with hemophilia. PATIENTS/METHODS: In this cross-sectional study, Dutch adults with hemophilia completed nine PROMIS item banks electronically. Feasibility was assessed by number of items and floor/ceiling effects. Reliability was determined as the proportion of reliable scores (standard error ≤3.2). Construct validity was assessed by comparison with legacy instruments and expected differences between subgroups. Relevance of item banks was determined by proportions of limited scores. RESULTS: Overall, 142 of 373 invited patients (mean age, 47 [range, 18-79], 49% severe hemophilia, 46% receiving prophylaxis) responded. Per CAT item bank, mean number of items answered varied from 5 (range, 3-12) to 9 (range, 5-12), with floor effects in pain interference (26% lowest scores) and depression (18% lowest scores). Construct validity and reliability were good for physical function, pain interference, satisfaction with social roles and activities, and fatigue. The CAT physical function showed the most limited scores (38%). The self-efficacy short forms showed ceiling effects (22%-28%) and no relation with the legacy instruments. CONCLUSIONS: The PROMIS CATs physical function, pain interference, satisfaction with social roles and activities, and fatigue are feasible, reliable, and valid alternatives to legacy instruments for patients with hemophilia, with few items and low floor-/ceiling effects.
RESUMO
INTRODUCTION: The Haemophilia Activities List (HAL) was developed to measure activities and participation in persons with haemophilia (PWH). Shortening the questionnaire may facilitate use of the HAL. AIM: The aim of this study was to determine which items of the HAL are redundant, to construct a shorter version of the HAL, and to determine the construct validity of the HALshort . METHODS: A secondary analysis was performed on pooled data of two published studies using the HAL (seven domains, 42 items, optimum score: 100) in adults with haemophilia A/B. Data were divided into a derivation (62%) and a validation set (38%). Redundant items were identified by evaluation of: 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. Correlations with the SF-36 and EQ-5D-5L were used to determine construct validity of the HALshort . RESULTS: Data on 680 PWH were evaluated. In the derivation dataset (n = 420), median age was 30 years (range 18-80), 43% had severe haemophilia and 61% received prophylaxis. Median (IQR) HAL sum score was 65.0 (55.7-88.8). The stepwise procedure resulted in a HALshort of 18 items with a median sum score of 63.3 (54.4-86.7). Construct validity was similar for the HAL and HALshort in the validation dataset (n = 260). CONCLUSION: This clinimetric study resulted in a >50% shortening of the HAL. The 18-item HALshort reduces patient burden and is expected to capture the information on activities and participation. The HALshort needs further validation.

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.

INTRODUCTION: The Haemophilia Activities List (HAL) is a preferred instrument to measure self-reported limitations in activities in persons with haemophilia (PWH). Information on reliability and interpretability of HAL scores is lacking. AIM: To examine the test-retest reliability and smallest detectable change (SDC) of the HAL in adult PWH. METHODS: Fifty adult (≥18 years) persons with mild to severe haemophilia completed the HAL (42 items, 7 domains, optimum 100) at baseline (T0) and 3-4 weeks later (T1). The intraclass correlation coefficient (ICC) and SDC were calculated for sum and component scores. RESULTS: Fifty persons with haemophilia were included (median age 49 years; 92% haemophilia A; 70% severe haemophilia). The median (interquartile ranges) HAL sum score was 77 (62 to 99) at T0 and 81 (64 to 98) at T1. Reliability was good with ICCs for sum and component scores >0.9. The SDC for the sum score was 10.2, for the upper extremity component score 9.2, for the basic lower extremity component score 16.7 and for the complex lower extremity component score 13.4. CONCLUSION: The HAL has a good reliability for the sum and component scores. Score changes of the normalized sum HAL score greater than the SDC 10.2 indicate that the change was not a result of measurement error.

INTRODUCTION: The Hemophilia Joint Health Score (HJHS) was developed to detect early changes in joint health in children and adolescents with haemophilia. The HJHS is considered by some to be too time consuming for clinical use and this may limit broad adoption. AIM: This study was a first step to develop a shorter and/or more convenient version of the HJHS for the measurement of joint function in children and young adults with haemophilia, by combining real-life data and expert opinion. METHODS: A cross-sectional multicenter secondary analysis on pooled data of published studies using the HJHS (0-124, optimum score 0) in persons with haemophilia A/B aged 4-30 was performed. Least informative items, scoring options and/or joints were identified. An expert group of 19 international multidisciplinary experts evaluated the results and voted on suggestions for adaptations in a structured meeting (consensus set at ≥ 80%). RESULTS: Original data on 499 persons with haemophilia from 7 studies were evaluated. Median age was 15.0 years [range 4.0-29.9], 83.2% had severe haemophilia and 61.5% received prophylaxis. Median (IQR) HJHS total was 6.0 (1.0-17.0). The items 'duration swelling' and 'crepitus' were identified as clinically less informative and appointed as candidates for reduction. CONCLUSION: Analysis of 499 children and young adults with haemophilia showed that the HJHS is able to discriminate between children and adults and different treatment regimens. Reduction of the items 'duration swelling' and 'crepitus' resulted in the HJHSshort , which had the same discriminative ability. Additional steps are needed to achieve a substantially shorter HJHS assessment.

BACKGROUND: Joint bleeds are the hallmark of hemophilia, leading to a painful arthritic condition called as hemophilic arthropathy (HA). Exercise programs are frequently used to improve the physical functioning in persons with HA. As hemophilia is a rare disease, there are not many physiotherapists who are experienced in the field of hemophilia, and regular physiotherapy sessions with an experienced physiotherapist in the field of hemophilia are not feasible for persons with HA. Blended care is an innovative intervention that can support persons with HA at home to perform the advised physical activities and exercises and provide self-management information. OBJECTIVE: The aim of this study was to develop a blended physiotherapy intervention for persons with HA. METHODS: The blended physiotherapy intervention, namely, e-Exercise HA was developed by cocreation with physiotherapists, persons with HA, software developers, and researchers. The content of e-Exercise HA was compiled using the first 3 steps of the Center for eHealth Research roadmap model (ie, contextual inquiry, value specification, and design), including people with experience in the development of previous blended physiotherapy interventions, a literature search, and focus groups. RESULTS: A 12-week blended intervention was developed, integrating face-to-face physiotherapy sessions with a web-based app. The intervention consists of information modules for persons with HA and information modules for physiotherapists, a graded activity program using a self-chosen activity, and personalized video-supported exercises. The information modules consist of text blocks, videos, and reflective questions. The patients can receive pop-ups as reminders and give feedback on the performance of the prescribed activities. CONCLUSIONS: In this study, we developed a blended physiotherapy intervention for persons with HA, which consists of information modules, a graded activity program, and personalized video-supported exercises.

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.

OBJECTIVE: The aim of this review was to investigate whether supervised home-based exercise therapy after hospitalization is more effective on improving functions, activities, and participation in older patients after hip fracture than a control intervention (including usual care). Furthermore, we aimed to account the body of evidence for therapeutic validity. DATA SOURCES: Systematic searches of Medline, Embase, and CINAHL databases up to June 30, 2016. STUDY SELECTION: Randomized controlled trials studying supervised home-based exercise therapy after hospitalization in older patients (≥65y) after hip fracture. DATA EXTRACTION: Two reviewers assessed methodological quality (Physiotherapy Evidence Database) and therapeutic validity (Consensus on Therapeutic Exercise Training). Data were primary analyzed using a best evidence synthesis on methodological quality and meta-analyses. DATA SYNTHESIS: A total of 9 articles were included (6 trials; 602 patients). Methodological quality was high in 4 of 6 studies. One study had high therapeutic validity. We found limited evidence in favor of home-based exercise therapy for short- (≤4mo) and long-term (>4mo) performance-based activities of daily living (ADL) and effects at long-term for gait (fast) and endurance. Evidence of no effectiveness was found for short- and long-term effects on gait and self-reported (instrumental) ADL and short-term effects on balance, endurance, and mobility. Conflicting evidence was found for strength, long-term balance, short-term gait (comfortable), long-term self-reported ADL, and long-term mobility. CONCLUSIONS: Research findings show no evidence in favor of home-based exercise therapy after hip fracture for most outcomes of functions, activities, and participation. However, trials in this field have low therapeutic validity (absence of rationale for content and intensity and reporting of adherence), which results in interventions that do not fit patients' limitations and goals.
