Equity and Disasters: Reframing Incident Command Systems

Centering Health Equity in the Implementation of the Hospital Incident Command System: A Qualitative Case Comparison Study

OBJECTIVE

Disasters exacerbate inequities in health care. Health systems use the Hospital Incident Command System (HICS) to plan and coordinate their disaster response. This study examines how 2 health systems prioritized equity in implementing the Hospital Incident Command System (HICS) during the coronavirus disease 2019 (COVID-19) pandemic and identifies factors that influenced implementation.

METHODS

This is a qualitative case comparison study, involving semi-structured interviews with 29 individuals from 2 US academic health systems. Strategies for promoting health equity were categorized by social determinants of health. The Consolidated Framework for Implementation Research (CFIR) guided analysis using a hybrid inductive-deductive approach.

RESULTS

The health systems used various strategies to incorporate health equity throughout implementation, addressing all 5 social determinants of health domains. Facilitators included HICS principles, external partnerships, community relationships, senior leadership, health equity experts and networks, champions, equity-stratified data, teaming, and a culture of health equity. Barriers encompassed clarity of the equity representative role, role ambiguity for equity representatives, tokenism, competing priorities, insufficient resource allocation, and lack of preparedness.

CONCLUSIONS

These findings elucidate how health systems centered equity during HICS implementation. Health systems and regulatory bodies can use these findings as a foundation to revise the HICS and move toward a more equitable disaster response.

Embedding Equity into the Hospital Incident Command System: A Narrative Review

BACKGROUND

Disasters exacerbate health inequities, with historically marginalized populations experiencing unjust differences in health care access and outcomes. Health systems plan and respond to disasters using the Hospital Incident Command System (HICS), an organizational structure that centralizes communication and decision-making. The HICS does not have an equity role or considerations built into its standard structure. The authors conducted a narrative review to identify and summarize approaches to embedding equity into the HICS.

METHODS

The peer-reviewed (PubMed, SCOPUS) and gray literature was searched for articles from high-income countries that referenced the HICS or Incident Command System (ICS) and equity, disparities, or populations that experience inequities in disasters. The primary focus of the search strategy was health care, but the research also included governmental and public health system articles. Two authors used inductive thematic analysis to assess commonalities and refined the themes based on feedback from all authors.

RESULTS

The database search identified 479 unique abstracts; 76 articles underwent full-text review, and 11 were included in the final analysis. The authors found 5 articles through cited reference searching and 13 from the gray literature search, which included websites, organizations, and non-indexed journal articles. Three themes from the articles were identified: including equity specialists in the HICS, modifying systems to promote equity, and sensitivity to the local community.

CONCLUSION

Several efforts to embed equity into the HICS and disaster preparedness and response were discovered. This review provides practical strategies health system leaders can include in their HICS and emergency preparedness plans to promote equity in their disaster response.
