Introduction Health Equity Impact Assessment (HEIA) is a decision support tool that shows users how a new pro‑gram, policy, or innovation affects health equity in different population groups. Various HEIA reporting and dissemina‑tion tools are available, nevertheless, a practical standard tool to present the results of HEIA in an appropriate period to policymakers is lacking. This work reports the development of a tool (a checklist) for HEIA reporting at the decision‑making level, aiming to promote the application of HEIA evidence for improving health equity.

Methods This is a mixed‑method study that was carried out over four stages in 2022–2023: 1) identifying HEIA mod‑els, checklists, and reporting instruments; 2) development of the initial HEIA reporting checklist; 3) checklist validation; and 4) piloting the checklist. We also analyzed the Face, CVR, and CVI validity of the tool.

Results We developed the initial checklist through analysis of 53 included studies and the opinions of experts. The final checklist comprised five sections: policy introduction (eight subsections), managing the HEIA of policy (seven subsections), scope of the affected population (three subsections), HEIA results (seven subsections), and recommen‑dations (three subsections).

Conclusion Needs assessment, monitoring during implementation, health impact assessment, and other tools such as monitoring outcome reports, appraisals, and checklists are all methods for assessing health equity impact. Other equity‑focused indicators, such as the equity lens and equity appraisal, may have slightly different goals than the HEIA. Similarly, the formats for presenting and publishing HEIA reports might vary, depending on the target population and the importance of the report.
