Introduction Patient-reported outcome measures (PROMs) are validated and standardised questionnaires that capture patients’ own reports of their symptoms, functioning and well-being. PROMs can facilitate communication between patients and clinicians, reduce symptom burden, enhance quality of life and inform health service re-design. We aim to determine the acceptability of PROMs and the preferred timing of PROM completion in New South Wales (NSW) at the point of care, facilitated by the Health Outcomes and Patient Experiences (HOPE) platform.Methods and analysis Semi-structured interviews with patients (~50-75, sampling across seven language groups and seven clinical cohorts), carers (~10–20) and clinicians (~18) enrolled in HOPE will be conducted via videoconference, telephone or in person. Participants will be asked questions about (1) what makes PROMs acceptable for use in chronic disease management (2) when patients would prefer to complete PROMs and when clinicians would like to use PROMs for clinical decision-making and (3) factors that impede the acceptability of PROMs for culturally and linguistically diverse patients. Interviews will be analysed using a reflexive thematic approach, guided by Normalisation Process Theory.Ethics and dissemination Ethics approval has been obtained from the Sydney Local Health District Human Research Ethics Committee (SLHD HREC, Study Protocol #X24-0138). Results will be published in appropriate peer-reviewed journals, presented at conferences, disseminated to participants in the form of a plain language summary, and widely disseminated to consumer groups and professional stakeholders.

Diffuse midline gliomas (DMG) are the most aggressive brain tumors of childhood and young adults, with documented 2-year survival rates 10nmol/L, or tumor tissue studies demonstrate CDK inhibition, then restart of abemaciclib therapy along with temozolomide will be administered for maintenance therapy and discontinued with evidence of radiologic or clinical disease progression. The poor survival associated with diffuse midline gliomas underscore the need for improved means to evaluate efficacy of drug delivery to tumor and peritumoral tissue. The findings of this novel study, will provide real-time measurements of BBB function which have the potential to influence future prognostic and diagnostic decisions in such a lethal disease with limited treatment options.
