Strategic Function: To establish temporary ambulatory care areas to handle excess patient volumes arising from an incident, acknowledging that due to limited resources and infrastructure, the most reasonable location is within existing healthcare facilities or in temporary structures near existing facilities.

Why: AOCAs can increase the efficiency of the delivery of acute care during an incident by handling the less severely injured and ill patients, thus reserving hospital emergency departments for the higher acuity patients. The mission of the AOCA is to:
- Direct patients affected by the incident, especially those who are non-critical patients, away from hospitals and emergency departments.
- Render basic medical screening and provision of medical care.
- Provide limited treatment.
- Provide distribution of prophylaxis, medication, self-help information, psychosocial support and instruction. .
Who: Local emergency managers and healthcare planners including but not limited to hospitals and primary care clinics, will best be able to determine the needs and ideal location(s) for AOCA(s).
When: Each community will decide through ongoing assessment, plan development and exercises, the trigger or threshold for the activation (and deactivation) of the AOCA(s).
Where: AOCA(s) should be within or adjacent to existing healthcare facilities to enable the redirection of patient flow and utilize existing staffing and resources.
How: The planning and establishment of an AOCA will be based on an assessment of the existing health care infrastructure in the community; and the process for resupply and resource management.
Planning assumptions for AOCA include:- Staffing of an AOCA will be structured to process the expected number of patients with personnel assigned based on predefined roles using screening and treatment protocols
- Patients arrive at the AOCA primarily by their own means.
- Patients requiring in-patient care are transported to either a hospital or an Alternate Inpatient Care Area (AICA).
- It is expected that the majority of patients will be discharged home or back into the community.
- Patients determined to be pre-terminal are accommodated, monitored and provided palliative care.
- Deceased patients are pronounced dead and transferred to the AOCA’s temporary morgue.
- Does the hospital or primary care clinic in the community have an identified alternate care location to direct a high volume of non-critically ill patients?
- Has the hospital or primary care clinic identified a trigger or threshold when alternate care areas needs to be established? What is the trigger and protocol for shutting the AICA down?
- Is there a plan to staff the alternative care area?
- Have supplies been identified (and or cached) to provide limited treatment and patient stabilization in the AICA?
- Does your community have a mass fatality plan?
- Is your community’s chief elected official involved in emergency operations
planning?

Facility Administrator Role in the Alternate Outpatient Care Areas (AOCA):
Define role and responsibilities of the facility administrator specific to AOCA.
Financial Tracking
Relates to tracking lost revenue and costs during incident response. Tracking should include investment in preparedness activities, lost revenue when closing inpatient beds, tracking hospital costs, and recovery after the incident.
