Real-world incidence of venetoclax toxicities in British Columbia.

INTRODUCTION: Venetoclax is used to treat relapsed/refractory chronic lymphocytic leukemia (r/r CLL). Tumour lysis syndrome (TLS) is a serious toxicity associated with venetoclax, and real-world studies suggest that the incidence may be higher than in clinical trials. The purpose of this study is to describe the incidence of venetoclax toxicities in British Columbia (BC). METHODS: Retrospective review of electronic medical charts for patient characteristics and clinical outcomes of patients treated with venetoclax for r/r CLL in BC. Patients were classified according to their risk for developing TLS. The incidence of TLS was categorized based on laboratory metrics or clinical diagnosis. Other non-TLS toxicities were also collected. RESULTS: Of 33 patients identified, 40%, 33%, and 27% were at low, intermediate, and high risk for TLS, respectively. Laboratory TLS occurred in 1/33 patients (3%), and no clinical TLS was reported. Grade 3 or 4 toxicities occurred in 19/33 patients (58%). Of these, neutropenia was the most common, occurring in 16 patients (84%) followed by thrombocytopenia, which occurred in 8 patients (42%). CONCLUSIONS: The incidence of TLS in patients treated with venetoclax for r/r CLL in BC was lower than in other real-world studies. Findings may warrant further investigation to determine if the higher incidence of TLS in real-world reports may be mitigated through modifying TLS risk categorization and associated prophylactic measures. Neutropenia was the most common grade 3 or 4 venetoclax toxicity reported, and the incidence in BC is comparable to other centres.

Using Virtual Learning to Develop Palliative Care Skills Among Humanitarian Health Workers in the Rohingya Refugee Response in Bangladesh.

Background: Palliative care is an essential component of health responses in humanitarian settings, yet it remains largely unavailable in these settings, due to limited availability of palliative care training for healthcare professionals. Online training programs which connect experts to clinicians in the field have been proposed as an innovative strategy to build palliative care capacity humanitarian settings. Objective: To describe the implementation and evaluate the impact of delivering palliative care education using an established virtual learning model (Project ECHO) for healthcare clinicians working in the Rohingya refugee response in Bangladesh. Program acceptability and the impacts on learners' self-reported knowledge, comfort, and practice changes were evaluated. Methods: Using the Project ECHO model, an education program consisting of 7 core sessions and monthly mentoring sessions was developed. Each session included a didactic lecture, case presentation and interactive discussion. Surveys of participants were conducted before and after the program to assess knowledge, confidence, and attitudes about palliative care as well as learning experiences from the program. Results: This virtual palliative care training program engaged 250 clinicians, including nurses (35%), medical assistants (28%) and physicians (20%). Most participants rated the program as a valuable learning experience (96%) that they would recommend to their colleagues (98%). Participants reported improvements in their knowledge and comfort related to palliative care after participation in the program, and had improved attitudes towards palliative care with demonstrated statistical significance (p < 0.05). Conclusions: Virtual training is a feasible model to support healthcare providers in a humanitarian health response. Project ECHO can help to address the urgent need for palliative care in humanitarian responses by supporting healthcare workers to provide essential palliative care to the growing number of individuals with serious health-related suffering in humanitarian settings.
