Evidence suggests that omission of family and caregiver health spillovers from the economic evaluation of healthcare interventions remains common practice. When accounted for, a high degree of methodological inconsistency has been observed.

The Spillovers in Health Economic Evaluation and Research (SHEER) task force has developed consensus guidance on the incorporation of family and caregiver health spillovers in cost-effectiveness and cost-utility analysis.

It is hoped that this report, detailing 11 consensus recommendations for emerging good practice and 12 avenues for future research, will motivate more widespread incorporation of health spillovers and expedite development of the spillover knowledge base.
