Differences in bleeding phenotype and provider interventions in postmenarchal adolescents when compared to adult women with bleeding disorders and heavy menstrual bleeding

Standardizing the evaluation and management of iron deficiency anemia secondary to heavy menstrual bleeding in the emergency department

BACKGROUND

Comprehensive guidelines for the management of iron deficiency anemia (IDA) in adolescents with heavy menstrual bleeding (HMB) presenting to the emergency department (ED) are lacking, leading to variability in care. We aimed to standardize the evaluation and management of these patients through the development and implementation of an evidence-based algorithm using quality improvement methodology.

METHODS

Baseline data of the target population identified variability across four key measures of clinical management: therapy choice and administration, laboratory evaluation, hematology service consultation, and patient disposition. Literature review and consensus from pediatric hematology and gynecology providers informed a draft algorithm that was refined in an iterative multidisciplinary process. From December 2022 to July 2023, we aimed to achieve a 25% relative increase in patients to receive optimal management per the algorithm, while using sequential Plan-Do-Study-Act (PDSA) cycles. Process measures focusing on provider documentation and balancing measures, such as ED length of stay, were assessed concurrently.

RESULTS

Forty-nine patients were evaluated during four PDSA cycles. Improvement of ≥40% above baseline regarding recommended therapy administration was achieved across four PDSA cycles. Adherence to recommended therapy choice improved from 57% (baseline) to 100%, minimal laboratory evaluation from 14% to 83%, hematology consultation from 36% to 100%, and appropriate disposition from 71% to 100%. ED length of stay remained stable.

CONCLUSION

Implementation of a standardized algorithm for management of IDA secondary to HMB in adolescents in the ED increased adherence to evidence-based patient care.

Heavy menstrual bleeding in adolescents: incidence, diagnostics, and management practices in primary care

BACKGROUND

Heavy menstrual bleeding (HMB), self-reported by 37% of adolescents, can be the first sign of a bleeding disorder (BD) during adolescence. The Dutch general practitioner (GP) guideline demands laboratory diagnostics and referral for patients at risk for a BD. How often adolescents consult the GP for HMB and which diagnostic and management strategies are used are unknown.

OBJECTIVES

This study aims to estimate the incidence of HMB in adolescents in primary care and to identify diagnostic and management practices for HMB, considering the HMB GP guideline.

METHODS

Retrospective analyses of a GP network database containing over 200 Dutch GPs were performed. Adolescents aged 10 to 21 years, with a new diagnosis of HMB between 2010 and 2020, and a 6-month follow-up were eligible. The incidence rate and diagnostic and therapeutic strategy data were extracted.

RESULTS

We identified 1879 new diagnoses of HMB in adolescents. The average incidence rate was 7.91 per 1000 person-years. No diagnostic studies were performed in 67%. Laboratory studies were mainly restricted to hemoglobin levels (31%). Full coagulation screening occurred in 1.3%, and ferritin levels in 10%. Medication was prescribed in 65%; mostly hormonal treatment (56%) and/or nonsteroidal antiinflammatory drugs (NSAIDs) (18%). The referral rate was higher after >2 follow-up visits (6.7%) vs after 1 GP visit for HMB (1.6%; Odds ratio: 8.8; 95% CI: 5.1-15), mostly to gynecologists (>85%).

CONCLUSION

According to this GP database study, few adolescents visit their GP with HMB despite its high self-reported incidence. Most adolescents were prescribed hormonal contraception without further diagnostics. Referral was rare and mostly occurred after multiple follow-up visits.

Building the foundation for a community-generated national research blueprint for inherited bleeding disorders: research to advance the health of people with inherited bleeding disorders with the potential to menstruate

BACKGROUND

People who have or had the potential to menstruate (PPM) with inherited bleeding disorders (BD) face particular challenges receiving appropriate diagnosis and care and participating in research. As part of an initiative to create a National Research Blueprint for future decades of research, the National Hemophilia Foundation (NHF) and American Thrombosis and Hemostasis Network conducted extensive all-stakeholder consultations to identify the priorities of PPM with inherited BDs and those who care for them.

RESEARCH DESIGN AND METHODS

Working group (WG) 4 of the NHF State of the Science Research Summit distilled community-identified priorities for PPM with inherited BDs into concrete research questions and scored their feasibility, impact, and risk.

RESULTS

WG4 identified important gaps in the foundational knowledge upon which to base optimal diagnosis and care for PPM with inherited BDs. They defined 44 top-priority research questions concerning lifespan sex biology, pregnancy and the post-partum context, uterine physiology and bleeding, bone and joint health, health care delivery, and patient-reported outcomes and quality-of-life.

CONCLUSIONS

The needs of PPM will best be advanced with research designed across the spectrum of sex and gender biology, with methodologies and outcome measures tailored to this population, involving them throughout.

The diagnosis, natural history, and management of von Willebrand disease in women in the age of guidelines

INTRODUCTION

Women and girls with bleeding disorders face multiple bleeding challenges throughout their life. The most significant morbidity and mortality are due to heavy menstrual bleeding and postpartum hemorrhage in their reproductive years. The ASH/ISTH/NHF/WFH 2021 guidelines on diagnosing and managing von Willebrand disease (VWD) provide several new updates.

AREAS COVERED

Women with VWD have a higher prevalence of heavy menstrual bleeding. The subpopulation of adolescents is particularly vulnerable, as the diagnosis is often delayed with increased comorbidity of iron deficiency anemia and associated symptoms. A detailed review is done on the prevalence of bleeding-related complications, especially heavy menstrual bleeding (HMB) and post-partum hemorrhage (PPH). The management strategies are also reviewed in detail, with a specific focus on the target factor levels and the use of antifibrinolytics.

EXPERT OPINION

The 2021 ASH/ISTH/NHF/WFH diagnostic and management recommendations are reviewed with a specific focus on hormonal methods of HMB management and antifibrinolytics in this situation. The reviewed topics include neuraxial anesthesia, factor cutoff, and tranexamic acid use in the postpartum period.

Bleeding Disorders in Women and Girls: State of the Science and CDC Collaborative Programs

Women and girls with bleeding disorders experience abnormal and excessive bleeding that can negatively impact their overall health and quality of life. In this report, we provide an overview of the biology, types, clinical care, and state of the science related to bleeding disorders in girls and women and describe Centers for Disease Control and Prevention (CDC) activities related to (1) surveillance of bleeding disorders in women; (2) scientific review, research, and collaboration to inform health care gaps in identifying and caring for women with bleeding disorders; and (3) development of health promotion and education programs to bring awareness about bleeding disorders to both women and girls in the population at large and various health care providers who care for women. Findings generated from surveillance and research activities inform the development of new public health programs aimed at improving diagnostic and health care services and empowering women with bleeding disorders with the knowledge they need to navigate a complex health care system with the need for specialty care services. Additional work is needed to improve provider awareness and understanding of the unique needs of women and girls with bleeding disorders to achieve appropriate care and treatment and ensure optimal outcomes and quality of life.

Complex family planning and pediatric hematology oncology integrated clinic for young people with blood disorders and heavy or abnormal menstrual bleeding

OBJECTIVES

To describe practice patterns of an integrated complex family planning-pediatric hematology oncology clinic for patients with blood disorders STUDY DESIGN: : We retrospectively evaluated the outcomes of patients who had an initial consultation for blood disorders impacting menstrual bleeding in an integrated complex family planning-pediatric hematology oncology clinic from October 2015 to September 2020. We reviewed all charts to extract medical and gynecologic history, blood disorder diagnosis, hormonal treatment prior to and following initial consultation, subsequent visits to the integrated clinic, and hormonal treatment up to 24 months after initial consultation.

RESULTS

We saw 47 patients; their most common blood disorder diagnosis was protein defect (14/47, 30%). Most patients (30/47, 64%) were not using any hormonal treatment prior to their initial consultation. After the initial consultation, 26 (55%) elected to start, change, or discontinue hormonal treatment for abnormal menstrual bleeding, the most common treatment being combined hormonal contraception (CHC, 22/47, 47%), alone or as dual therapy. Over the study duration, 36 patients (77%) initiated, changed, or discontinued their hormone treatment, 22 (61%) of whom changed their treatment plan more than once. CHC usage decreased from 19/47 (40%) to 8/37 (22%) and hormonal device usage, particularly the implant, increased from 9/47 (19%) to 11/37 (30%) over the 24 months from initial consultation.

CONCLUSION

Most patients in an integrated complex family planning-pediatric hematology oncology clinic will change their menstrual bleeding hormone treatment with initial consultation, although management may require multiple changes. The most common treatment 24 months following the initial consultation was hormonal devices.

IMPLICATIONS

Patients with blood disorders affecting menstrual bleeding have complex needs that could be addressed by an integrated complex family planning-pediatric hematology oncology clinic. Most patients require multiple changes in treatment to achieve adequate control of their bleeding, and patients were more likely to choose hormonal devices for management over time.

European principles of care for women and girls with inherited bleeding disorders

INTRODUCTION

Despite increasing awareness of issues faced by women and girls with inherited BDs (WGBD), standards of care are lacking, with disparities in diagnosis and treatment for WGBD across Europe. We aimed to develop practical principles of care (PoC) to promote standardization of care for WGBD within European Haemophilia Treatment and Comprehensive Care Centres (HTC/CCCs).

METHODS

The co-creation process, supported by the European Association for Haemophilia and Allied Disorders, consisted of four multidisciplinary meetings with health care providers (HCPs) experienced in WGBD care, and European Haemophilia Consortium representatives, combined with broad patient and HCP consultations in the European haemophilia community. Relevant medical societies outside Europe were contacted for confirmation.

RESULTS

We developed ten PoC for WGBD, stressing the importance and benefits of a centralized, multidisciplinary, comprehensive, family-centred approach to support and manage WGBD during all life stages. These PoC emphasise the right to equitable access and quality of care for all people with BDs, irrespective of gender. Multiple medical societies outside Europe also confirmed their support for endorsement.

CONCLUSIONS

Ten PoC for WGBD evolved from an iterative process among stakeholders, supported by relevant medical societies worldwide. These PoC can serve as a benchmark for diagnosis and comprehensive multidisciplinary management of WGBD, and improve awareness of their unique challenges. They offer a framework to guide HTC/CCCs in providing equitable care for all WGBD, both in their own services and in other healthcare settings. Implementation of these principles aims to positively impact the health, wellbeing and quality of life for WGBD.

Identified unmet needs and proposed solutions in mild-to-moderate haemophilia: A summary of opinions from a roundtable of haemophilia experts

INTRODUCTION

The experiences of patients with mild-to-moderate haemophilia differ from those of patients with severe haemophilia or those without a bleeding disorder and include a challenging diagnosis and variability in bleeding symptoms and treatment needs. In addition, there is a significant lack of data on mild-to-moderate haemophilia, and many unmet needs remain to be identified and addressed in this group of patients.

METHODS

Challenges for these patients, including women with haemophilia, were identified during a roundtable meeting attended by a group of US-based experts including healthcare professionals (e.g., physicians, nurses, and physical therapists) and patients who live with a bleeding disorder.

RESULTS

Identified unmet needs included a lack of proper education on the management of their disorder and prompt treatment of bleeds, absenteeism from school and work, and challenges with personal relationships. Initiatives to assist with alleviating these unmet needs were proposed and include suggestions for healthcare professionals, haemophilia treatment centres (HTCs) and national and local organizations within the bleeding disorders community. These included HTC and community engagement programmes for patients with mild-to-moderate haemophilia, revised transition guidelines for these patients as they approach adulthood and revised diagnostic classification of mild and moderate haemophilia. Challenges unique to women with haemophilia and ways to address these issues were also discussed.

CONCLUSION

This paper summarizes the challenges, initiatives and suggestions that were identified by the haemophilia experts during the roundtable meeting.

Standardizing care to manage bleeding disorders in adolescents with heavy menses-A joint project from the ISTH pediatric/neonatal and women's health SSCs

BACKGROUND

Bleeding disorders (BD) are under-recognized in adolescents with heavy menstrual bleeding (HMB).

OBJECTIVES

The lack of clinical guidelines and variable symptomatic management of HMB created the imperative to standardize HMB care to identify and manage BD in adolescents.

METHODS

We convened an international working group (WG), utilized the results of a literature review to define knowledge gaps in HMB care, and used the collective clinical experience of the WG to develop care considerations for adolescents with BD and HMB. We then solicited input on the appropriateness of HMB care considerations from expert stakeholders representing hematology, adolescent medicine, and obstetrics-gynecology. We conducted an expert panel online, using the ExpertLens platform. During a three-round online modified-Delphi process, the expert panel rated the appropriateness of 21 care considerations using a 9-point scale to designate care as appropriate (7-9), uncertain (4-6), or inappropriate (1-3) covering screening for BD, the laboratory work-up, and management of adolescents with BD that present with HMB. We used the RAND/UCLA appropriateness method to determine the existence of consensus among the interdisciplinary panel of experts.

RESULTS

Thirty-nine experts participated in the panel. The experts rated fifteen HMB care considerations as appropriate, six as uncertain, and none as inappropriate.

CONCLUSIONS

The HMB care statements represent the first set of HMB care considerations in adolescents with BD, developed with broad expert input on appropriateness. Although likely to be of interest to a range of clinicians who routinely manage adolescents with HMB, additional research is required in many key areas.

The spectrum and severity of bleeding in adolescents with low von Willebrand factor-associated heavy menstrual bleeding

Low von Willebrand factor (VWF) in adults is associated with significant bleeding, most notably heavy menstrual bleeding (HMB) and postpartum hemorrhage, although this has not been characterized in adolescents. The objectives of this analysis of a multicenter single arm observational cohort study in adolescents with low VWF-associated HMB were to describe the bleeding phenotype, HMB severity, and related complications. Eligibility criteria included postmenarchal females <21 years of age with HMB (Pictorial Blood Assessment Chart [PBAC] score >100) and low VWF (2 values of VWF activity ≥30 and ≤50 IU/dL). Patients diagnosed with other bleeding disorders were ineligible. Clinical phenotype data, including PBAC and Bleeding Assessment Tool (BAT) scores, laboratory data, and HMB management/outcome details, were extracted. Patient demographics and clinical characteristics were summarized as medians with minimum/maximum values or frequencies with percentages. Groups were compared using a Wilcoxon rank-sum test or Fisher's exact test. A total of 113 patients met inclusion criteria, and 2 were excluded. Ninety four percent had a significant bleeding phenotype (BAT score >2), with predominantly mucocutaneous bleeding (32%-44%), postprocedural/surgical bleeding (15%), and severe HMB (BAT HMB domain score ≥2; 90%). Bleeding complications included iron deficiency (60%), anemia (21%), transfusion (12%), and hospitalization (10%). Desmopressin challenge response in subjects tested was good and sustained. Several (48%) required combined therapy for HMB (hormonal/hemostatic), and one third did not show improvement despite therapy. Our results suggest that adolescent females with low VWF have a significant bleeding phenotype and resultant complications warranting a focus on prompt diagnosis, appropriate therapy, and prevention of complications.

Occurrence rates of haemophilia among males in the United States based on surveillance conducted in specialized haemophilia treatment centres

INTRODUCTION

Estimates of the size and characteristics of the US haemophilia population are needed for healthcare planning and resource needs assessment. A network of comprehensive haemophilia treatment centres (HTCs) located throughout the United States receives federal support for diagnosis and management of haemophilia and other rare bleeding disorders.

AIM

Estimate the incidence and prevalence of haemophilia among US males using the HTC network.

METHODS

During the period 2012-2018, de-identified surveillance data were collected on all males who visited an HTC that included year of birth, gender, race, Hispanic ethnicity, residence zip code, haemophilia type and severity. Data from all patients were used to calculate period prevalence by haemophilia type, severity and state of residence. Data from a subset of patients born 1995-2014 were used to estimate incidence rates over the 20-year period.

RESULTS

During the period, 21 748 males with haemophilia visited the HTCs resulting in an age-adjusted prevalence of 15.7 cases per 100 000 males (12 for haemophilia A and 3.7 for haemophilia B). Prevalence was higher among whites (15.1) than blacks (12.4) or Hispanics of either race (12.4). State-specific prevalence varied from 1.6 to 23.3 cases per 100 000. Based on 9587 males born during the index period, the average haemophilia incidence was 1 case per 4334 live male births.

CONCLUSION

Based on these data, we estimate that there are between 29 761 and 32 985 males with haemophilia living in the United States today, the majority of whom receive comprehensive care in specialized clinical centres.
