ABSTRACT

Background: Cancer is associated with increased venous thromboembolism in children. Risk factors for venous thromboembolism in this cohort include using central venous catheters, mass effect from underlying malignancy, chemotherapy, and surgery. Anticoagulation management in this cohort is challenging, given recurrent episodes of thrombocytopenia, the need for invasive procedures, and coagulopathy. A quality improvement (QI) initiative was developed to improve hematology consultation services and provide documentation of an individualized anticoagulation care plan for this high-risk cohort. Methods: Through the use of QI methods, interviews of stakeholders, expert consensus, and review of baseline data, a multidisciplinary team was organized, and key drivers relevant to improving access to hematology consultations and documentation of individualized anticoagulation care plans were identified. We used a Plan-Do-Study-Act model to improve hematology consultations and documentation of anticoagulation care plan (process measure). Outcome measures were bleeding and thrombosis recurrence/progression. Results: Seventeen patients with oncologic and venous thromboembolism diagnoses were included as baseline data. Slightly over half of these patients [53% (n = 9)] had a hematology consultation, and 7 (43.8%) had documentation of an anticoagulation care plan. After implementing QI methods, all 34 patients (100%) received hematology consultations and documentation of an anticoagulation care plan, and this measure was sustained for 1 year. Bleeding and thrombosis rates were similar in the baseline and post-QI cohorts. Conclusions: QI interventions proved effective in sustaining access to hematology consultations and providing anticoagulation care plans for patients with concomitant improved anticoagulation plan documentation for patients.

ABSTRACT

BACKGROUND: Evidence-based anticoagulation programs usually serve a local, adult patient population. Here we report outcomes for a regional combined pediatric-adult program. AIMS: The aims of this study were: (1) Compare the pre- vs. post-implementation quality of therapy (% time in therapeutic range (%TTR) and compliance). (2) Assess anticoagulant-relevant outcomes (bleeding and thrombotic complications). METHODS: Data were collected for the years 2014-2019. Rosendaal linear interpolation was used to calculate %TTR. Bleeding complications were categorized using ISTH-SSC standard nomenclature and new thrombotic events were reviewed. RESULTS: The patients were divided into a long-term warfarin group (N = 308), 80.2% of whom had cardiac-related therapeutic indications (median age 24y), and a second group (N = 114) comprised of short-term and non-warfarin long-term anticoagulation (median age 16y). Median %TTR for those on long-term warfarin was 78.9%. The incidence of major and clinically relevant non-major bleeding events was 1.65 and 2.43 /100 person-years of warfarin use, respectively. Thromboembolism (TE) incidence was 0.78/100 patient-years of warfarin use. Neither bleeding nor thrombosis was associated with %TTR (p = 0.48). Anticoagulant indication was the only variable associated with bleeding risk (p = 0.005). The second group had no on-therapy TE events but 7.9% experienced bleeding. Complete data were available for a randomly sampled pre-program warfarin group (N = 26). Median %TTR improved from 17.5 to 87% pre- vs. post-implementation. Similarly, compliance (defined as ≥ 1 INR/month) improved by 34.3%. CONCLUSIONS: In conclusion, this program significantly improved and sustained %TTR and compliance. The lack of association between bleeding and thrombosis events and %TTR may be related to the high median %TTR (> 70%) achieved by this approach.

ABSTRACT

An innovative approach to anticoagulation management during the COVID-19 pandemic was used at our center that allowed patients to stay in their vehicle while our anticoagulation advanced practice registered nurse obtained blood for point-of-care international normalized ratio (INR) testing while education and counseling were completed. A significant improvement in the median percentage of INR within the therapeutic range was observed among the patients who used the drive-through clinic. A small group of patients improved compliance to anticoagulation monitoring. Clinical care models, such as this clinic approach may improve patient compliance and adherence to anticoagulation beyond the pandemic needs.

ABSTRACT

Hypodysfibrinogenemia, the least frequently reported congenital fibrinogen disorder is characterized by low circulating levels of a dysfunctional protein, and is associated with phenotypic features of both hypo- and dysfibrinogenemia. Herein, we report an adolescent male with unprovoked venous thromboembolism and hypodysfibrinogenemia. Patient had recurrent, progressive thrombosis despite therapeutic anticoagulation with both low molecular weight heparin and warfarin. He had clinical and radiological improvement after transition to a direct thrombin inhibitor. Sequencing of the FGG gene identified a novel heterozygous mutation, c.1075G>T. Structural visualization of the identified variant was pursued and suggested that the mutation likely destabilizes the Ca2+ -binding site of fibrinogen resulting in pathogenicity.
