High-yield AGCNS-BC study priorities
Priority 1
Think in three spheres
For every case, identify the patient-level need, the nursing-practice implication, and the organizational or system lever.
Priority 2
Make implementation measurable
Link each intervention to a stakeholder, resource, change strategy, outcome measure, balancing measure, and reassessment point.
Priority 3
Practise evidence-to-system translation
Use cases that move from literature appraisal through stakeholder engagement, implementation, data review, sustainability, and spread.
Priority 4
Integrate regulation and finance
Do not study accreditation, policy, risk, reimbursement, and resource allocation separately from clinical quality decisions.
