Hazard Vulnerability Assessment

A regional Hazard Vulnerability Assessment (HVA) was conducted in 2017 to analyze the risks of large-scale emergency or disaster events within AzCHER-Central’s service area. Development of the Coalition HVA is similar to development of the organizational HVA. The coalition identifies and prioritizes the likely hazards the region could face, which often overlap with the hazards that members identify in their organizational HVAs.


AzCHER-Central’s Planning Committee conducted the Coalition HVA using the Community-Based Vulnerability Assessment (CBVA) tool. It is based on the Kaiser Permanente HVA tool that many healthcare institutions are currently using. The probability and potential severity of events are used to calculate risk, or relative threat. Events that are considered include natural hazards (e.g., earthquake and volcano eruption), technological hazards (e.g., utility failure and information systems failure), human hazards (e.g., mass casualty incident and civil disturbance), and hazardous materials (e.g., chemical and radiologic exposure). The Planning Committee’s recommendations were approved by the General Body in December of 2017.


The group assessment removed organization-specific vulnerabilities to focus on community-wide risks. The vulnerabilities were sorted and prioritized, taking into account the significant impact on personnel and mission-critical elements. The complete assessment can be viewed as an Excel file here.

In response to the regional HVA and in continuation of efforts to conduct trainings and exercises that will prepare the Central Region healthcare sector to collectively respond to an adverse event, the MYTEP is under development and will be available on this site once completed. The purpose of the MYTEP will be to aid AzCHER-Central in providing local healthcare emergency response planners with guidance and recommendations to accomplish the following at the local level:

  • Identify the priorities for improving the preparedness and response capabilities of the organization
  • Define the cycle of training and exercise activities that will provide the most benefit in the development, refinement, and maintenance of those capabilities

While the MYTEP is intended to cover a period of three years, the regional HVA will updated annually to ensure the healthcare community is responsive to those threats and vulnerabilities that are most pressing for the entire region.
