Introduction
The 2005 Gulf Coast hurricane season was one of the most costly and deadly in US history. Hurricane Rita stressed hospitals and led to multiple, simultaneous evacuations. This study systematically identified community factors associated with patient movement out of seven hospitals evacuated during Hurricane Rita.
MethodsThis study represents the second of two systematic, observational, and retrospective investigations of seven acute care hospitals that reported off-site evacuations due to Hurricane Rita. Participants from each hospital included decision makers that comprised the Incident Management Team (IMT). Investigators applied a standardized interview process designed to assess evacuation factors related to external situational awareness of community activities during facility evacuation due to hurricanes. The measured outcomes were responses to 95 questions within six sections of the survey instrument.
ResultsInvestigators identified two factors that significantly impacted hospital IMT decision making: (1) incident characteristics affecting a facility's internal resources and challenges; and (2) incident characteristics affecting a facility's external evacuation activities. This article summarizes the latter and reports the following critical decision making points: (1) Emergency Operations Plans (EOP) were activated an average of 85 hours (3 days, 13 hours) prior to Hurricane Rita's landfall; (2) the decision to evacuate the hospital was made an average of 30 hours (1 day, 6 hours) from activation of the EOP; and (3) the implementation of the evacuation process took an average of 22 hours. Coordination of patient evacuations was most complicated by transportation deficits (the most significant of the 11 identified problem areas) and a lack of situational awareness of community response activities. All evacuation activities and subsequent evacuation times were negatively impacted by an overall lack of understanding on the part of hospital staff and the IMT regarding how to identify and coordinate with community resources.
ConclusionHospital evacuation requires coordinated processes and resources, including situational awareness that reflects the condition of the community as a result of the incident. Successful hospital evacuation decision making is influenced by community-wide situational awareness and transportation deficits. Planning with the community to create realistic EOPs that accurately reflect available resources and protocols is critical to informing hospital decision making during a crisis. Knowledge of these factors could improve decision making and evacuation practices, potentially reducing evacuation times in future hurricanes.

Introduction
Hurricanes remain a major threat to hospitals throughout the world. The authors attempted to identify the planning areas that impact hospital management of evacuations and the challenges faced when sheltering-in-place.
MethodsThis observational, retrospective cohort study examined acute care institutions from one hospital system impacted by Hurricane Rita in 2005. Investigators used a standardized survey instrument and interview process, previously used in the hospital evacuation context, to examine hospitals’ initial internal situational awareness and subsequent decision making that resulted in evacuation due to Hurricane Rita. Participants from each hospital included representatives from senior leadership and clinical and nonclinical staff that comprised the Incident Management Team (IMT). The main measured outcomes were responses to 95 questions contained in the survey.
ResultsSeven of ten eligible hospitals participated in the study. All facilities evacuated the sickest patients first. The most significant factors prompting evacuation were the issuing of mandatory evacuation orders, storm dynamics (category, projected path, storm surge), and loss of regional communications. Hospitals that sheltered-in-place experienced staff shortages, interruptions to electrical power, and loss of water supplies. Three fully-evacuated institutions experienced understaffing of 40%-60%, and four hospitals sustained depressed staffing levels for over four weeks. Five hospitals lost electricity for a mean of 4.8 days (range .5-11 days). All facilities continued to receive patients to their Emergency Departments (EDs) while conducting their own evacuation.
ConclusionHospital EDs should plan for continuous patient arrival during evacuation. Emergency Operation Plans (EOPs) that anticipate challenges associated with evacuation will help to maximize initial decision making and management during a crisis situation. Hospitals that shelter-in-place face critical shortages and must provide independent patient care for prolonged periods.
