Defining the quality of interdisciplinary care for patients with brain metastases: modified Delphi panel recommendations.

The value of interdisciplinary teams in improving outcomes and quality of care of patients with brain metastases remains uncertain, partly due to the lack of consensus on key indicators to evaluate interprofessional care. We aimed to obtain expert consensus across disciplines on indicators that evaluate the quality and value of brain metastases care. A steering committee of key opinion leaders curated relevant outcomes and process indicators from a literature review and a stakeholder needs assessment, and an international panel of physicians rated the outcomes and process indicators using a modified Delphi method. After three rounds, a consensus was reached on 29 indicators encompassing brain-directed oncological treatment, surgery, whole-brain radiotherapy, stereotactic radiosurgery, supportive or palliative care, and interdisciplinary team care. The Brain Metastases Quality-of-Care measure reflects the value and quality of brain metastases team-based care according to treatment modality and provides a benchmark of care for this under-studied patient population. The adoption, implementation, and sustainability of this set of indicators could help address the need expressed by patients with cancer, caregivers, and clinicians for more coordinated care across inpatient, outpatient, home, community, and tertiary academic settings.
