Introduction
Hurricane Ida made landfall at 11:55am outside Port Fourchon, Louisiana (USA) as a Category-4 hurricane with maximum sustained winds reaching ∼150 mph on August 29, 2021. National weather services were tracking the storm as early as August 23, which developed first as a tropical depression but reached hurricane strength winds three days after development. Given the relative speed of Ida as it approached inland, mandatory evacuations were not issued for the majority of the New Orleans (Louisiana USA) area, leading to many of the disaster activation issues further discussed.
Since Hurricane Katrina (2001), no storm has rendered New Orleans uninhabitable for such a sustained period of time. Reference McSwain1,Reference Raulji, Velez, Prasad, Rousseau and Gardner2 Owing to the knowledge acquired from Hurricane Katrina, Orleans Parish did not suffer extensive flooding and/or critical infrastructure water damage. However, Hurricane Ida presented a new issue by way of sustained wind-speeds that proved devastating to the electrical grid responsible for providing energy to the approximately 380,000 residents and 40,000 businesses in the greater New Orleans Metropolitan Area. Approximately 30 resident deaths were attributed to the storm itself. Lack of power and wind damage resulted in the loss of several key local hospitals within the first 24 hours, complicating both post-storm health care efforts as well as the concurrent management of the COVID-19 Delta-variant surge.
Louisiana State University (LSU) New Orleans - Emergency Medicine (EM) Residency Program’s hurricane response protocol, designated “Code Grey,” has required activation four times since Hurricane Katrina in 2001. Despite the relative infrequency of use, this structured plan is discussed and revised on an annual basis to reflect the most current, anticipated needs of the city, the hospital, and the EM program should a substantial hurricane occur. However, despite this dedication to preparedness, at the time of Hurricane Ida, the last implementation pre-dated all current residents (EM physicians in training) and several members of the core faculty. As such, many of the lessons and knowledge gleaned after the last official activation were not readily available. Thus, it fell to the leadership and chief residents to quickly adapt by building an efficient, flexible response plan to ensure resident safety while still providing the quality patient care that serves as the foundation of the residency program.
The Hurricane Ida EM resident disaster response protocol was reviewed by the LSU Health Sciences Center-NO IRB on Thursday, March 31, 2022 and was determined to NOT be Human Subjects Research: Protocol #: 4005.
Data and Information Source
This field report is based upon debriefing sessions and after-action reports conducted post-storm and discusses logistical pitfalls and the subsequent lessons drawn during a real-time hurricane disaster response. Residency debriefing sessions occurred between chief residents and residency classes in the form of a standard residency forum. Additionally, the LSU EM post-disaster committee, composed of residents, academic faculty, and ancillary personnel, convened a separate meeting with hospital administrative-level leadership for full examination. These sessions were solely for the purpose of generating feedback regarding the efficacy of the program’s response to the many challenges posed by Hurricane Ida. The information obtained was then used by the chief residents to develop a more formalized Code Grey process, as well as future orientation and education materials for residents.
Observations
Each academic year, LSU EM residents receive correspondence from the chief resident presiding over development of the Code Grey disaster response team. At that time, important information is disseminated to the program regarding essential processes to successfully navigate a hurricane disaster response. In the days immediately preceding Hurricane Ida, daily contact chains from hospital administration, chief residents, and emergency department (ED) leadership were established to ensure the most up-to-date information was available to all residents.
On August 28, 2021, the decision was made to activate the University Medical Center New Orleans (UMCNO)’s hospital-wide hurricane disaster response, the morning of anticipated Ida landfall, with subsequent activation of the program-specific Code Grey protocols at 7:00am. This included an in-house lock-down of faculty, residents, and auxiliary staff until relief teams were dispatched post-storm. However, residents scheduled to work on August 28th expressed concern about their ability to evacuate post-shift, prior to the hurricane reaching Orleans Parish. As such, the decision was made to activate Code Grey on the night of August 28, allowing the residency’s disaster response evening team to relieve house staff 12-hours earlier than initiation of the hospital’s official lock-down. Post-hurricane debriefing indicated that having the activation staff in place at a minimum of 24-hours prior to hospital lock-down would have been preferable, as this would have allowed for ample opportunity for resident evacuation and preparation.
On initiation of Code Grey, all residents not on the activation team were excused from clinical duties and advised to either evacuate the area or shelter in place, as a “mandatory” evacuation order for the New Orleans area was not in effect. As such, highway and airport closures in the adjacent gulf region complicated coordination and initiation of the post-storm relief considering many residents who were members of the recovery team evacuated to locations >500 miles or >48 hours outside of New Orleans. Residency leadership, many of whom were also working as members of the ED activation team, quickly had to locate residents near enough and who could return safely to be part of the immediate post-storm recovery team.
Relief team ED staffing was challenging due to issues with communication, evacuation locations, and city-wide safety concerns. Approximately two days preceding Ida landfall, an online spreadsheet was sent to all ED residents requiring evacuation location with address, phone number, and miscellaneous needs regarding evacuation. This allowed residents easy access to the most current location data of program members and allowed Code Grey leadership to use the document to verify the safety of evacuated residents. Correspondence favored the activation team in the days leading up to the storm. Few organized discussions occurred with residents assigned to the recovery team regarding evacuation location, comfort with and plan for returning safely, and post-storm living conditions. Subsequently, many residents’ evacuation locations led to difficulties getting people back into town. New Orleans’ main airport, Louis Armstrong International, was shut down in the week following the storm, making it difficult for residents to report for relief duty without navigating multiple logistical barriers and incurring significant personal monetary costs.
Additionally, the eye of Hurricane Ida passed due northwest of New Orleans, resulting in the prolonged closure of I-10, the major highway leading from both Baton Rouge, Louisiana and Houston, Texas (USA). As the next closest major metropolitan areas within driving distance of New Orleans, both cities were logical evacuation sites for residents. Closures of I-10 thus created additional delays in recalling multiple relief team members. To compound this issue, many non-activation residents chose to carpool on evacuation, for both camaraderie and to consolidate resources. This created inevitable delays and logistical challenges when recalling specific individuals. The final major hurdle for post-storm staffing, from a man-power perspective, pertained to the on-going infrastructural issues in the city, especially from a safety and housing perspective. City-wide extended power outages, impassable streets, and wide-spread residential damage forced city officials to issue “stay-away” warnings to evacuated residents desiring to return soon after the storm threat had dissipated. The question of “How safe is safe enough?” to insist that people return, especially considering conflicting local government warnings, led to internal debates among hospital and program administration regarding an appropriate timeline to recall residents in a safe and organized manner.
Summer in New Orleans is notoriously hot and humid, posing actual health risks to those without air conditioning. Many residents expressed concerns about returning to areas without power and/or hurricane-related damage. A significant amount of time was spent securing safe lodging for relief members returning to the city, through hospital call rooms, individuals with generators allowing residents to stay with them, and eventually with program and Federal Emergency Management Agency (FEMA; Washington, DC USA)-sponsored hotel rooms. These safety concerns (and the resources needed to address them), in conjunction with issues of communication, disparities in evacuation plans, and storm-driven geographical hurdles, made putting together a practical recovery team difficult.
Discussion
As a result of feedback and knowledge acquired, the following changes have been made to the residency’s Code Grey activation plan:
-
1. Code Grey ED activation will start a minimum of 24 hours prior to the hospital’s activation so that individuals scheduled pre-storm have adequate time to safely evacuate.
-
2. Recovery team members should plan to return between the third and fifth day at 7:00am for clinical duties in the ED. To do this, they will need to stay within a 500-mile radius. Residents should make every attempt to drive to evacuation locations, since flying is an unreliable method of travel post-storm.
-
3. Nightly emails from the program director/chief residents summarizing continued and evolving plans are a highly effective way to reach out to residents that will continue in future activations.
-
4. Evacuating with a group will not be accepted as an excuse for delays in returning to duties.
-
5. The city may discourage city residents from returning to town after a major storm that caused damage to infrastructure, resulting in delays in relief staff returning to the city. Program and hospital leadership will need to work with the city to determine when it is safe for essential personnel to return and to anticipate the need to provide essential services such as housing and feeding for relief staff.
-
6. Regarding resident scheduling:
-
a. If a resident is on maternity/paternity leave, they will be assigned as unavailable for activation.
-
b. Combined residents (EM/Internal Medicine or EM/Peds) currently on EM rotations will be assigned as priority alternates. If a resident is on Pediatrics or Internal Medicine at the time of the Code Grey, they cannot be on the EM activation team since they will be needed on their respective services.
-
c. If a resident on the activation/recovery team is on/about to start vacation during the activation period, an alternate resident will be swapped into their place.
-
d. Residents on intensive care unit (ICU) rotations will not be activated to the ICU’s activation team but are expected back for ICU duties early as part of the ICU recovery team.
-
e. Ensuring the main-site and off-service scheduling chiefs are available during the day during an activation allows for a better understanding of critical staffing needs.
-
f. Having an overnight chief on call, working clinically, is helpful for managing emergencies that occur overnight.
-
The most consistent feedback received from residents during debriefing sessions is regarding the need for expedited, frequently updated information on how, when, and where to evacuate in the event of an impending major storm and anticipated Code Grey activation. Program interns, many of whom matriculated to New Orleans from out-of-state/region and had never experienced an actual hurricane event, found the Hurricane Ida activation logistics particularly overwhelming. As such, the program has worked to create evolving hurricane evacuation documents to include updated and formalized protocols based on the major lessons gleaned from Hurricane Ida. These will be distributed at the start of each residency year and in advance of any major hurricane expected to impact the New Orleans area. In addition, the residency plans to incorporate hurricane preparation and evacuation training into the annual intern orientation.
