Patient-reported outcomes in autosomal inherited bleeding disorders: A systematic literature review.

AIM: Currently, it is unknown which patient-reported outcomes are important for patients with autosomal inherited bleeding disorders. Therefore, the purpose of this study is to systematically review the available literature assessing patient-reported outcomes and their measurement methods in autosomal inherited bleeding disorders. METHODS: The Embase, Medline ALL, Web of Science Core Collection, Cochrane Central Register of Controlled Trails and Google Scholar databases were searched from inception until 14 August 2020. Studies on patient-reported outcomes in patients with von Willebrand disease, inherited platelet function disorders and coagulation factor deficiencies were included. RESULTS: Twenty-one articles met the inclusion criteria. Three studies were assessed as having poor quality, and therefore a high risk of bias. Nineteen studies had fair quality rating. Different measurements methods were used, ranging from predefined to self-developed questionnaires. The majority of included studies focused on von Willebrand disease. Patients with von Willebrand disease reported lower health-related quality of life compared to the general population. Overall, this trend was especially visible in the following domains: vitality, physical and social functioning and pain. Women with inherited bleeding disorders scored lower on health-related quality of life compared to men, especially women with heavy menstrual bleeding. Patients with joint bleeds or heavy menstrual bleeding reported an increased level of pain. CONCLUSION: Patients with autosomal inherited bleeding disorders report lower health related quality of life, especially those with joint bleeds or heavy menstrual bleeding. Numerous measurement methods are used in patients with autosomal inherited bleeding disorders, highlighting the need for studies using established, standardized measurement methods.

Patient experiences with value-based healthcare interventions at the HIV outpatient clinic of the Erasmus Medical Centre.

BACKGROUND: One of the aims of value-based healthcare (VBHC) is to deliver more patient-centred care. However, little is known about the effect of VBHC interventions on patient experiences. We aim to explore how patients experience VBHC as implemented in an HIV outpatient clinic in an academic hospital in the Netherlands. METHODS: The HIV outpatient clinic of the Erasmus MC, Rotterdam, the Netherlands, an academic tertiary hospital, implemented a VBHC intervention consisting of 1) implementation of a generic quality of life questionnaire, administered before each visit, 2) a change in consultation schedule; from twice a year face-to-face to one face-to-face double consultation and one remote consultation per year, and 3) a change in consultation structure; from a single face-to-face consultation with the infectious diseases (ID) specialist to a double consultation in which the patient visits both the nurse and the ID specialist. Semi-structured interviews were held with Dutch or English-speaking adult patients, that had been a patient within Erasmus MC for more than 5 years, on their experiences with the implemented changes. RESULTS: Thirty patients were interviewed. Patients had no objections towards completing the questionnaires especially if it could provide the professionals with additional information. Patients were primarily positive about the change in consultation schedule. For the yearly remote consultation they preferred a telephone-consultation above a video-consultation. The change in consultation structure ensured that more topics, including psychosocial and medical aspects could be discussed. Some patients did not see the added value of talking to two professionals on the same day or completing the quality of life questionnaire before their consultation. CONCLUSION: Patients are generally positive towards the VBHC interventions implemented at the HIV outpatient clinic. Our findings may inform further optimization of VBHC interventions and improve patient-centred care in outpatient HIV clinics.

Value-Based Integrated Care: A Systematic Literature Review.

BACKGROUND: Healthcare services worldwide are transforming themselves into value-based organizations. Integrated care is an important aspect of value-based healthcare (VBHC), but practical evidence-based recommendations for the successful implementation of integrated care within a VBHC context are lacking. This systematic review aims to identify how value-based integrated care (VBIC) is defined in literature, and to summarize the literature regarding the effects of VBIC, and the facilitators and barriers for its implementation. METHODS: Embase, Medline ALL, Web of Science Core Collection, and Cochrane Central Register of Controlled Trails databases were searched from inception until January 2022. Empirical studies that implemented and evaluated an integrated care intervention within a VBHC context were included. Non-empirical studies were included if they described either a definition of VBIC or facilitators and barriers for its implementation. Theoretical articles and articles without an available full text were excluded. All included articles were analysed qualitatively. The Rainbow Model of Integrated Care (RMIC) was used to analyse the VBIC interventions. The quality of the articles was assessed using the Mixed Methods Appraisal Tool (MMAT). RESULTS: After screening 1328 titles/abstract and 485 full-text articles, 24 articles were included. No articles were excluded based on quality. One article provided a definition of VBIC. Eleven studies reported-mostly positive- effects of VBIC, on clinical outcomes, patient-reported outcomes, and healthcare utilization. Nineteen studies reported facilitators and barriers for the implementation of VBIC; factors related to reimbursement and information technology (IT) infrastructure were reported most frequently. CONCLUSION: The concept of VBIC is not well defined. The effect of VBIC seems promising, but the exact interpretation of effect evaluations is challenged by the precedence of multicomponent interventions, multiple testing and generalizability issues. For successful implementation of VBIC, it is imperative that healthcare organizations consider investing in adequate IT infrastructure and new reimbursement models.

The ethics of gene therapy for hemophilia: a narrative review.

Gene therapy is expected to become a promising treatment, and potentially even a cure, for hemophilia. After several years of research, the first gene therapy product has been granted conditional market authorization by the European Union in August 2022. The recent progress in the field also has implications on the ethical aspects of hemophilia gene therapy. Reviews conducted in the 2000s mainly identified questions on the ethics of conducting early-phase clinical trials. However, since then, the knowledge on safety and efficacy has improved, and the field has moved toward clinical application, a phase that has its own ethical aspects. Therefore, we conducted a narrative review to take stock of the ethical aspects of hemophilia gene therapy. Based on our analysis of the literature, we identified 3 ethical themes. The theme Living up to expectations describes the existing hopes for gene therapy and the unlikelihood of the currently approved product becoming a permanent cure. In the theme Psychosocial impacts, we discuss the fear that gene therapy will impact the identity of people with hemophilia and their need for psychosocial support. The theme Costs and access discusses the expected cost-effectiveness of gene therapy and its implications on accessibility worldwide. We conclude that it may be necessary to change the narratives surrounding gene therapy, from describing it as a cure to describing it as one of the many treatments that temporarily relieve symptoms and that there is a need to reevaluate the desirability of gene therapy for hemophilia, given the availability of other treatments.

Patient-relevant health outcomes for von Willebrand disease, platelet function disorders, and rare bleeding disorders: a Delphi study.

Background: To assess patient value, it is essential to regularly measure health outcomes that matter to patients. It is currently unknown which health outcomes are important for patients with autosomal inherited bleeding disorders. Objectives: This study aimed to assess which health outcomes are important for patients with autosomal inherited bleeding disorders, consisting of von Willebrand disease, platelet function disorders, and rare bleeding disorders, as seen from the patients', caregivers', and healthcare professionals' perspectives. Methods: Two panels, one consisting of patients and caregivers, and one consisting of healthcare professionals participated in a Delphi process. A list of 146 health outcomes was identified from the literature. During 3 rounds, both panels rated the importance of health outcomes on a 5-point Likert scale. A health outcome was considered important by a panel if it received a median score of 5 with an IQR of ≤1. Results: In total, 13 patients, 10 caregivers, and 19 healthcare professionals participated in the Delphi study. Both panels reached consensus on the importance of health outcomes related to bleeding episodes, life-threatening complications, and the intensity and impact of menstruation. Patients and caregivers additionally reached consensus on the importance of health outcomes related to menstruation and the impact of the bleeding disorder on their daily lives. Healthcare professionals reached consensus on the importance of health outcomes related to treatment, joint health, and pain. Conclusion: In this study, health outcomes were identified that should be considered when implementing value-based health care in the care of patients with autosomal inherited bleeding disorders.

Psychometrics of the patient-reported outcomes measurement information system measures in hemophilia: the applicability of the pediatric item banks.

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.

Generic PROMIS item banks in adults with hemophilia for patient-reported outcome assessment: Feasibility, measurement properties, and relevance.

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.
