RESUMEN
INTRODUCTION: As a result of centralisation of haemophilia care to a limited number of intramural settings, many persons with haemophilia have to travel long distances to attend their haemophilia specialised treatment centre. However, regular physiotherapy treatment can be provided by primary care physiotherapists in the person's own region. Due to the rarity of the disease most primary care physiotherapists have limited experience with this population. This study aims to provide a clinical practice guideline for primary care physiotherapists working with persons with bleeding disorders. METHOD: A list of the most urgent key-questions was derived from a previous study. Literature was summarised using the grading of recommendations assessment, development, and evaluation (GRADE) evidence-to-decision framework. Recommendations were drafted based on four 90 min consensus meetings with expert physiotherapists. Recommendations were finalised after feedback and >80% consensus of all stakeholders (including PWH, physiotherapists, haematologists and the corresponding societies). RESULTS: A list of 82 recommendations was formulated to support primary care physiotherapists when treating a person with a bleeding disorder. These recommendations could be divided into 13 categories: two including recommendations on organisation of care, six on therapy for adult patients with bleeding disorders and five on therapy adaptations for paediatric care. Therapy recommendations included treatment after a joint- or muscle bleed, haemophilic arthropathy, chronic synovitis, non-haemophilia related conditions and orthopaedic surgery. CONCLUSION: An evidence-based practice guideline, based on current evidence from literature and clinical expertise, has been developed for primary care physiotherapists treating a person with haemophilia. To improve care, the recommendations should be implemented in daily practice.
RESUMEN
OBJECTIVE: T2-relaxometry could differentiate between physiological and haemorrhagic joint effusion (≥ 5% blood) in vitro. Are quantitative T2-relaxation time measurements of synovial fluid feasible and reproducible in vivo in clinically bleed-free joints of men with haemophilia? MATERIALS AND METHODS: In this cross-sectional study, we measured T2-relaxation times of synovial fluid in clinically bleed-free ankles, knees or elbows of men with severe haemophilia A using a T2-mapping sequence (duration ≤ 7 min) at 3 Tesla MRI. Manual and circular regions of interest (ROI) were drawn in the synovial fluid of each joint by two independent observers to measure T2-relaxation times. Measurement feasibility was expressed as the success rate of the measurements by both observers. The interobserver and intraobserver reproducibility of the measurements were evaluated by the intraclass correlation coefficient of absolute agreement (ICC) and the limits of agreement (LoA) from Bland Altman analysis. RESULTS: We evaluated 39 clinically bleed-free joints (11 ankles, 12 knees, 16 elbows) of 39 men (median age, 24 years; range 17-33) with severe haemophilia A. The success rate of the T2-measurements was ≥ 90%. Interobserver reliability was good to excellent (manual ROI: ICC = 0.92, 95% CI 0.76-0.97; circular ROI: ICC = 0.82, 95% CI 0.66-0.91) and interobserver agreement was adequate (manual ROI: LoA = 71 ms; circular ROI: LoA = 146 ms). Intraobserver reliability was good to excellent (manual ROI: ICC = 0.78, 95% CI - 0.06-0.94; circular RO: ICC = 0.99, 95% CI 0.98-0.99) and intraobserver agreement was good (manual ROI: LoA = 63 ms; circular ROI: LoA = 41 ms). CONCLUSION: T2-relaxometry of synovial fluid in haemophilia patients is feasible with good interobserver and intraobserver reproducibility.
RESUMEN
INTRODUCTION: Ultrasound is increasingly used as addition to physical examination for detection of subclinical joint changes in haemophilia. However, the added value of ultrasound to physical examination for detecting synovial proliferation is not fully established. AIM: To determine the diagnostic accuracy of swelling at physical examination for ultrasound-detected synovial proliferation in haemophilia. METHODS: PubMed and EMBASE were searched up to 2 August 2022. Studies reporting original data on occurrence of swelling at physical examination and synovial proliferation on ultrasound of index joints in persons with haemophilia were included. Risk of bias and applicability were assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool. Diagnostic accuracy parameters of swelling at physical examination for ultrasound-detected synovial proliferation were determined. Summary sensitivity and specificity were calculated using a bivariate random-effects model. RESULTS: Fifteen studies reporting on swelling at physical examination and synovial proliferation on ultrasound in 2890 joints of 627 patients were included. Prevalence of subclinical synovial proliferation ranged between 0% and 55%. Sensitivity of swelling was low [summary estimate .34; 95% confidence interval (CI) .24-.46], while specificity was high (summary estimate .97; CI .92-.99). Predictive values varied widely due to inter-study differences in prevalence of synovial proliferation. CONCLUSION: Joint swelling has low sensitivity for presence of ultrasound-detected synovial proliferation in haemophilia, suggesting underestimation of synovial proliferation by physical examination alone. Consequently, ultrasound screening may generate important information on synovial changes which would otherwise remain undetected.

INTRODUCTION: The World Haemophilia Federation advises regular musculoskeletal assessment covering all International Classification of Functioning and Health (ICF) domains, including limitations in activities and participation in persons with haemophilia (PWH). This enables clinicians to detect changes early and enable adjustments in personalized healthcare when needed. However, data on the course of physical functioning and occurrence of decline is lacking. The aim of this study is to describe changes in perceived limitations in activities of PWH and to identify factors associated with a change. METHODS: Data were collected from medical health records of regular check-up visits of adults with moderate and severe haemophilia in two time periods. Perceived limitations in activities was measured with the Haemophilia Activities List (HAL). Association between variables (e.g., age, body mass index, bleeding rate and synovitis) and change in perceived limitations was assessed using a generalized linear model. RESULTS: A total of 104 PWH were included. At T0, the median HAL sum score was 79.5 (IQR 62.1-93.6) and at T1 the median HAL sum score was 74.2 (IQR 57.5-88.3). A functional decline was found in 35.6% of PWH, 55.8% remained stable and 8.7% improved. Among other variables, a BMI > 30 kg/m2 appeared to be an important factor that negatively influenced the change in perceived functioning in adult PWH. With the included factors we could only explain a small part of this decline (R2 adj : .12). CONCLUSION: The majority of PWH remained stable in their perceived functional ability over mid-long term (median 3.5 years). However, about a third showed a clinical relevant decline in their functional ability.

AIM: Traditionally, recovery after a joint bleed in people with bleeding disorders is evaluated by clinical symptoms. Following a bleed, however, asymptomatic joints may still show synovial hypertrophy and effusion on ultrasound. We evaluated the duration of full recovery from a joint bleed. Additionally, we determined how recovery differed when assessed by physical examination and ultrasound. METHODS: In this retrospective cohort study, we investigated joint bleeds in elbows, knees and ankles of people with haemophilia or Von Willebrand disease who attended the Van Creveldkliniek between 2016 and 2021. Physical examination (warmth, swelling, range of motion and gait) and ultrasound (effusion and synovial hypertrophy) were performed within 7 days after the onset of the bleed, 1 week after the first examination and monthly thereafter until patients had recovered fully. Joint bleeds were treated in line with the current international treatment guidelines. RESULTS: We evaluated 30 joint bleeds in 26 patients. The median recovery time was 1 month (range 0.3-5 months). In 47% of the joint bleeds, the recovery took longer than 1 month. The moment of recovery based on physical examination and ultrasound differed in 27% of bleeds. Both persistent abnormalities at physical examination in joints with normalized ultrasounds and persistent ultrasound findings in clinically recovered joints occurred. CONCLUSION: Joint bleed recovery can take long and recovery times differed per bleed. Recovery differed when assessed by physical examination or ultrasound. Therefore, both should be used to closely monitor recovery of joint bleeds and offer personalized care.

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.

BACKGROUND: Patients with haemophilia experience recurring hemarthroses, mainly involving knees, elbows and ankles, which lead to haemophilic arthropathy, the major chronic complication of haemophilia. With new approaches to haemophilia treatment leading to fewer joint bleeds and, in some cases, no bleeding events, assessing whether current outcome assessment tools provide adequate sensitivity and specificity for management and care of patients with haemophilia is needed. METHODS: An overview of current imaging tools for monitoring joint health, novel osteochondral damage and synovial proliferation biomarkers, and the relationship between assessments for functionality and imaging modalities is provided. Usefulness and sensitivity of point-of-care ultrasound (POCUS) to complement other assessments and use of ultrasound to monitor haemophilic arthropathy are also examined. RESULTS: This review provides rationale for haemophilia teams to move beyond traditional outcomes in joint imaging, as well as guidance and evidence on assessment of joint health for potential new treatment modalities, such as gene therapy. The role of POCUS in the existing paradigm for haemophilia care and management along with the use of ultrasound as a complement to other outcome assessment tools are also discussed. Finally, the clinical effects of subclinical bleeding on joint function are described, to motivate screening for synovial proliferation. CONCLUSION: POCUS can facilitate the early detection of joint damage and can monitor disease progression while providing insights into the efficacy of treatment regimens, and should be considered as an essential assessment tool for managing the care of patients with haemophilia.

AIM: Subclinical bleeding and inflammation play a role in progression of haemophilic arthropathy. Synovial proliferation is predictive of joint bleeding and its early detection may guide treatment changes and prevent arthropathy progression. This study evaluated the prevalence of active and inactive subclinical synovial proliferation and investigated potential biochemical blood/urine markers to identify patients with active subclinical synovial proliferation. METHODS: This cross-sectional study included patients with severe haemophilia A born 1970-2006 who were evaluated during routine clinic visits. Patients with (a history of) inhibitors or recent joint bleeding were excluded. Elbows, knees and ankles were examined for subclinical synovial proliferation by ultrasound and physical examination. Active synovial proliferation was distinguished from inactive synovial proliferation using predefined criteria. Blood/urine biochemical markers (serum osteopontin, sVCAM-1, Coll2-1, COMP, CS846, TIMP, and urinary CTX-II) were compared individually and as combined indexes between patients with and without active synovial proliferation. RESULTS: This cohort consisted of 79 patients with a median age of 31 years (range 16.5-50.8 years) with 62/79 (78%) of the patients using continuous prophylaxis. The annualized joint bleeding rate over the last 5 years was .6 (.2-1.1). Active (17/79, 22%) and inactive subclinical synovial proliferation (17/79, 22%) were both prevalent in this cohort. Biochemical markers were not correlated with active subclinical synovial proliferation. CONCLUSION: Subclinical synovial proliferation, both active and inactive, was prevalent in patients with severe haemophilia A with access to prophylaxis and would be overlooked without routinely performed ultrasounds. Biochemical markers were unable to identify patients with active subclinical synovial proliferation.

INTRODUCTION: Physiotherapy is highly recommended for persons with haemophilia (PWH), to regain functioning after bleeding and to maintain functioning when dealing with haemophilic arthropathy. However, many PWH live too far from their Haemophilia Comprehensive Care Centre (HCCC) to receive regular treatment at their HCCC. Physiotherapists in primary care may have limited experience with a rare disease like haemophilia. AIM: To explore experiences of stakeholders with primary care physiotherapy for PWH and develop recommendations to optimize physiotherapy care coordination. METHODS: A RAND approach was used, consisting of a Delphi procedure with e-mailed questionnaires and a consensus meeting. Included stakeholders were PWH, physiotherapists from HCCC's and primary care physiotherapists. HCCC physiotherapists approached patients from their centre and primary care physiotherapists from their network to fill in the questionnaires. Purposive sampling was used to select participants from the survey sample for the consensus meeting. RESULTS: Ninety-six primary care physiotherapists, 54 PWH and eight HCCC physiotherapists completed the questionnaire. Subsequently, four PWH, three primary care physiotherapists and four HCCC physiotherapists participated in the consensus meeting. The questionnaires yielded 33 recommendations, merged into a final list of 20 recommendations based on the consensus meeting. The final rank-order consists of 13 recommendations prioritized by at least one stakeholder. CONCLUSION: Commitment to a formal network is considered not feasible for a rare disease like haemophilia. Development of a practice guideline, easy-accessible information and contact details, two-way and open communication between HCCC and primary care and criteria to refer back to the HCCC are recommended.

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.

INTRODUCTION: Sports participation in children with hemophilia is generally considered to be associated with increased injury risk, which is generally considered highest in severe hemophilia. AIM: To assess sports participation according to age and severity in children with hemophilia and its association with sports injuries. METHODS: In a retrospective single-center study, sports participation, injuries, and bleeding data from three consecutive annual clinic visits were collected for young patients with hemophilia (PWH, aged 6-18). Sports in categories 2.5 and 3 of 3 according to the National Hemophilia Foundation classification were considered high-risk. Groups were compared using chi-square testing. RESULTS: 105 PWH (median age: 13(IQR 10-14); 53% severe; bleeding rate: 1/y) were identified; three were unable to perform sports and were excluded. The majority of PWH (77%) played sports weekly, of which 80% high-risk sports. Sports participation (median 3.0x/wk), and the proportion of injured PWH was similar in severe (42%) and non-severe (33%) PWH. Sports injuries were rare (65% no injuries in 3 years, median 0/y (IQR 0-1)). Annually, PWH did not report more injuries (15%) than age-matched boys (28%). Sports injuries were not associated with frequency and type of sports. DISCUSSION: This retrospective study showed high sports participation (including high-risk sports) and low injury rates. Sports participation was similar across severities and injury rates were not higher than among the general population. Injuries were not associated with frequency or type of sports. A prospective study with objective assessment of sports participation and injuries is warranted to confirm these findings and avoid recall bias.

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: Accurate assessment of joint health in persons with haemophilia is crucial. Several haemophilia-specific measurement tools are available, but an overview of the measurement properties is lacking. AIM: To provide an overview of the measurement properties of haemophilia-specific measurement tools to assess clinical joint health. METHODS: MEDLINE and EMBASE were searched for reports on reliability, validity or responsiveness of the World Federation of Haemophilia Orthopedic Joint Score (WFH), Colorado Physical Examination Score (CPE), joint examination score by Petrini (PJS) and Hemophilia Joint Health Score (HJHS). Methodological quality of the studies was assessed using an adapted COSMIN checklist. RESULTS: The search yielded 2905 unique hits, and 98 papers were included. The methodological quality of the included studies was limited. The HJHS was studied most extensively, which yielded limited evidence for good internal consistency and structural validity, moderate evidence for hypothesis testing in adults and conflicting evidence for hypothesis testing in children. Reliability, measurement error and responsiveness were rated unknown due to low COSMIN scores. For the CPE and PJS, we found limited to moderate evidence for good responsiveness and conflicting evidence for hypothesis testing. CONCLUSION: Only patchy evidence is available on the quality of measurement properties of all haemophilia-specific joint health scores. Although significant gaps in the evidence for all instruments remain, measurement properties of the HJHS were most extensively studied and show no drawbacks for use in clinical practice. This review forms the basis for further research aimed at the assessment of measurement properties of measurement tools to assess joint health.

Background: Ultrasound is increasingly used for musculoskeletal assessment in hemophilia care. Objectives: To evaluate the impact of point-of-care ultrasound added to clinical assessment for diagnosis and treatment of acute musculoskeletal episodes in a heterogeneous cohort of children and adults with hemophilia and von Willebrand disease (VWD). Methods: This prospective cross-sectional study consecutively included children and adults with hemophilia or VWD who visited the outpatient clinic with acute musculoskeletal complaints between March 2020 and May 2023. For all episodes, initial diagnosis and treatment determined by clinical assessment were recorded on a case report form. Subsequently, a physiotherapist (M.A.T. and J.B.) with knowledge of the clinical diagnosis performed point-of-care ultrasound. After ultrasound, updated diagnosis and treatment were recorded. Diagnosis and treatment before and after ultrasound were compared, and proportions of change with 95% CIs were determined. Results: We evaluated 77 episodes in 67 patients (median age, 24 years; IQR, 13-42 years). Before ultrasound, 37 joint bleeds, 13 muscle bleeds, and 27 other diagnoses were diagnosed. After ultrasound, 33 joint bleeds, 11 muscle bleeds, and 33 other diagnoses were confirmed. The diagnosis changed in 28 of 77 episodes (36%; 95% CI, 26%-48%). Nine joint bleeds and 2 muscle bleeds were missed by clinical assessment. Ultrasound findings changed treatment strategy in 30 of 77 episodes (39%; 95% CI, 28%-51%). Conclusion: Ultrasound in addition to clinical assessment of acute musculoskeletal complaints in people with hemophilia and VWD has an impact on diagnosis (36%) and treatment (39%), which supports the use of ultrasound in acute musculoskeletal complaints in hemophilia and VWD.
RESUMEN
BACKGROUND: Previous studies suggest that subclinical bleeding occurs in persons with hemophilia. OBJECTIVES: The aim of this study was to investigate whether patients with lifelong access to prophylaxis showed signs of previous subclinical bleeding on magnetic resonance imaging (MRI) in joints without a history of joint bleeding. METHODS: This single-center cross-sectional study included persons with severe hemophilia A on prophylaxis, aged 16 to 33 years, with lifetime bleeding records available. Per participant, 1 index joint without a history of joint bleeding was evaluated with 3-Tesla MRI, including hemosiderin sensitive sequences. MRI scans were reviewed according to the International Prophylaxis Study Group (IPSG) additive MRI scale (range, 0-17/joint). Hemosiderin deposits with/without synovial hypertrophy were considered signs of previous subclinical bleeding. Additionally, physical examination was performed, followed by ultrasound examination according to the Hemophilia Early Arthropathy Detection with Ultrasound protocol. RESULTS: In 43 patients with a median age of 23.5 years, 43 joints (16 elbows, 13 knees, 14 ankles) without reported bleeds were evaluated with MRI. The median IPSG MRI score was 1 (range, 0-9). Signs of previous subclinical bleeding were observed in 7 of 43 joints (16%; 95% CI, 7-30): 7 of 7 joints showed hemosiderin deposits, with concomitant synovial hypertrophy in 2 of 7 joints. MRI changes were accompanied by swelling and ultrasound-detected synovial hypertrophy in 1 ankle only. None of the other joints showed abnormalities at physical examination and ultrasound. CONCLUSION: In this study, 16% of the joints without reported bleeds showed signs of previous subclinical bleeding, providing evidence for subclinical bleeding in people with severe hemophilia with lifelong access to prophylaxis.

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.
RESUMEN
BACKGROUND: Joint bleeds are the hallmark of haemophilia, and can lead to disabling haemophilic arthropathy. Consequently, the movement behaviour of adults with haemophilia differs from that of healthy adults. It seems unlikely that a single outcome is able to reflect all relevant information regarding movement behaviour. The aim of the current study was to identify patterns of movement behaviour within persons with haemophilia (PWH) and compare clinical characteristics between patterns of movement behaviour. METHODS: A total of 105 PWH [70% severe haemophilia; median age 43 years (30.0-54.0)] were included in the study. Hierarchical cluster analysis was used to identify patterns of movement behaviour. Clustering variables included seven parameters of movement behaviour: sitting, standing, walking, biking, running, frequency of active bouts and length of active bouts. Clinical characteristics included age, severity of haemophilia, joint health, physical functioning and pain. Clinical characteristics were compared between identified clusters by Kruskall-Wallis test. Movement behaviour was assessed with the Activ8 accelerometer, joint health was assessed on the Haemophilia Joint Health Score, physical functioning on the Haemophilia Activity List and the 40 m self-paced walk test and pain on the Numerical Pain Rating Score. RESULTS: Cluster analysis identified three clusters, which were defined as: 'sedentary' (57%), 'bikers and runners' (22%) and 'walkers' (20%). The 'bikers and runners' showed better joint health and experienced fewer limitations in activities than the 'walkers' and the 'sedentary'. The 'walkers' perceived fewer limitations in activities than the 'sedentary', with comparable joint health. We did not identify differences in pain, walking speed and age between the clusters. CONCLUSIONS: We identified three patterns of movement behaviour. The majority of PWH was identified as sedentary, whereas less sitting and regular walking during the day seemed to be more beneficial.
RESUMEN
Introduction Standardized bleeding assessment tools (BATs), such as the International Society for Thrombosis and Hemostasis (ISTH)-BAT, are screening instruments used during the diagnostic workup of suspected bleeding disorders. A self-administered ISTH-BAT (self-BAT) would enhance screening and save time during an outpatient clinic visit. Aim This study was aimed to investigate the reliability and feasibility of the self-BAT. Methods The electronic self-BAT was created from the ISTH-BAT and paper-version of self-BAT and optimized by patients and physicians. Patients with a (suspected) congenital platelet defect (CPD), who had previously undergone physician-administered ISTH-BAT assessment, were invited to complete the self-BAT. Optimal self-BAT cut-off values to detect a bleeding tendency, as defined by the ISTH-BAT, were evaluated by receiver operator characteristic (ROC) curve analysis to reach a sensitivity ≥95%. Reliability was tested by assessing sensitivity, specificity, and intraclass correlation (ICC). Feasibility was evaluated on comprehension and length of self-BAT. Results Both versions of the BAT were completed by 156 patients. Optimal cut-off values for self-BAT to define a bleeding tendency were found to be identical to those of the ISTH-BAT. Normal/abnormal scores of the ISTH-BAT and self-BAT were agreed in 88.5% (138/156, 95% confidence interval [CI]: 0.83-0.93) of patients. The sensitivity and specificity of the self-BAT to detect a bleeding tendency were 96.9 and 48.1%, respectively. The ICC was 0.73. Self-BAT questions were graded by 96.8% (151/156) as "very easy," "easy," and "satisfactory" and questionnaire length as "exactly right" by 91% (142/156) of patients. Conclusion In patients with a (suspected) CPD, the self-BAT is sufficiently reliable and feasible to detect a bleeding tendency, which supports its use as a screening tool.
