RESUMO
Empyema resulting as a complication of penetrating diaphragmatic injuries is a subject that requires further investigation, and the aim of this study was to determine the risk factors associated with empyema in patients with penetrating trauma. Consecutive adult trauma patients from a level 1 trauma center were searched for penetrating diaphragm injuries. Data were collected on patient demographics, pre-existing conditions, injury type and severity, hospital interventions, in-hospital complications, and outcomes. Patients were stratified by empyema formation and univariant analyses were performed. 164 patients were identified, and 17 patients (10.4%) developed empyema. Empyema was associated with visible abdominal contamination (35.3% vs 15%, P = .04), thoracotomy (35.5% vs 13.6%, P = .03), pneumonia (41.2% vs 14.3%, P = .01), sepsis (35.3% vs 8.8%, P = .006), increased hospital length of stay (25.5 vs 10.1 days, p =<.001), increased intensive care unit length of stay (9.6 vs 4.3 days, P = .01), and decreased in-hospital mortality (0% vs 20.4%, P = .04).

INTRODUCTION: The United States has one of the highest rates of gun violence and mass shootings. Timely medical attention in such events is critical. The objective of this study was to assess geographic disparities in mass shootings and access to trauma centers. METHODS: Data for all Level I and II trauma centers were extracted from the American College of Surgeons and the Trauma Center Association of America registries. Mass shooting event data (4+ individuals shot at a single event) were taken from the Gun Violence Archive between 2014 and 2018. RESULTS: A total of 564 trauma centers and 1672 mass shootings were included. Ratios of the number of mass shootings vs trauma centers per state ranged from 0 to 11.0 mass shootings per trauma center. States with the greatest disparity (highest ratio) included Louisiana and New Mexico. CONCLUSION: States in the southern regions of the US experience the greatest disparity due to a high burden of mass shootings with less access to trauma centers. Interventions are needed to increase access to trauma care and reduce mass shootings in these medically underserved areas.

Traumatic abdominal wall hernias are a rare complication of high energy blunt trauma. There exist several studies evaluating and outlining potential management options but still no generalized consensus on management. This series was meant to evaluate the diagnosis and management of traumatic abdominal wall hernias. A prospectively maintained database was used to identify patients with TAWH from 2021 to 2022. The primary outcome was operative management. Secondary outcomes included: time to diagnosis and post-operative outcomes. Of the 19 patients in this case series, 100% (n = 19/19) were secondary to blunt trauma with a mean ISS of 21. Exploratory laparotomy was performed in 17 cases. 14 cases had concomitant traumatic injuries to visceral structures. Complications were found in nearly half of the patients with 3 experiencing wound dehiscence. Future studies should be aimed at standardizing management approach taking into account nature of the mechanism and concomitant injuries.
RESUMO
BACKGROUND: The standard for managing traumatic pneumothorax (PTX), hemothorax (HTX), and hemopneumothorax (HPTX) has historically been large-bore (LB) chest tubes (>20-Fr). Previous studies have shown equal efficacy of small-bore (SB) chest tubes (≤19-Fr) in draining PTX and HTX/HPTX. This study aimed to evaluate provider practice patterns, treatment efficacy, and complications related to the selection of chest tube sizes for patients with thoracic trauma. METHODS: A retrospective chart review was performed on adult patients who underwent tube thoracostomy for traumatic PTX, HTX, or HPTX at a Level 1 Trauma Center from January 2016 to December 2021. Comparison was made between SB and LB thoracostomy tubes. The primary outcome was indication for chest tube placement based on injury pattern. Secondary outcomes included retained hemothorax, insertion-related complications, and duration of chest tube placement. Univariate and multivariate analyses were performed. RESULTS: Three hundred and forty-one patients were included and 297 (87.1%) received LB tubes. No significant differences were found between the groups concerning tube failure and insertion-related complications. LB tubes were more frequently placed in patients with penetrating MOI, higher average ISS, and higher average thoracic AIS. Patients who received LB chest tubes experienced a higher incidence of retained HTX. DISCUSSION: In patients with thoracic trauma, both SB and LB chest tubes may be used for treatment. SB tubes are typically placed in nonemergent situations, and there is apparent provider bias for LB tubes. A future randomized clinical trial is needed to provide additional data on the usage of SB tubes in emergent situations.

BACKGROUND: ER-Resuscitative Endovascular Balloon Occlusion of the Aorta (ER-REBOA) is an adjunct tool to achieve hemostasis in trauma patients with non-compressible torso hemorrhage. The development of the partial REBOA (pREBOA) allows for distal perfusion of organs while maintaining occlusion of the aorta. The primary aim of this study was to compare rates of acute kidney injury (AKI) in trauma patients who had placement of either a pREBOA or ER-REBOA. METHODS: A retrospective chart review of adult trauma patients who underwent REBOA placement between September 2017 and February 2022 was performed. Baseline demographics, information on REBOA placement, and post-procedure complications including AKI, amputations, and mortality were recorded. Chi-squared and T-test analyses were performed with P < .05 considered to be significant. RESULTS: A total of 68 patients met study inclusion criteria with 53 patients (77.9%) having an ER-REBOA. 6.7% of patients treated with pREBOA had a resulting AKI, while 40% of patients treated with ER-REBOA had a resulting AKI, and this difference was significant (P < .05). The rates of rhabdomyolysis, amputations, and mortality were not significantly different between the two groups. CONCLUSION: The results from this case series suggest that patients treated with pREBOA have a significantly lower incidence of developing an AKI compared to ER-REBOA. There were no significant differences in rates of mortality, and amputations. Future prospective studies are needed to further characterize the indications and optimal use for pREBOA.

Intravenous (IV) fluids are one of the most widely prescribed medications. Despite their frequent usage, IV fluids are often not used appropriately. High-quality evidence to guide the surgeon in the perioperative period is sparse. A plethora of choices for IV fluids exists with limited evidence to help guide the surgeon in specific patient populations and situations. To address this, the authors have set out to provide a critical review of commonly used IV fluids to treat surgical patients. Gaps in the existing literature for the surgical population will also be discussed as potential target areas for future research.

Automobile collisions with driver side intrusion >12 inches or >18 elsewhere meet criteria for trauma activation. However, vehicle safety features have improved since this inception. We hypothesized vehicle intrusion (VI) alone as mechanism-of-injury (MOI) criteria inadequately predicts trauma center activation. A retrospective, single-center chart review of adult patients involved in motor vehicle collisions presenting to a level 1 trauma center from July 2016 to March 2022 was performed. Patients were divided by MOI criteria: VI vs. multiple MOI criteria. 2940 patients met inclusion criteria. The VI group reported lower injury severity scores (P = 0.004), higher incidence of ED discharge (P = 0.001), lower ICU admissions (P = 0.004), and fewer in-hospital procedures (P = 0.03). Vehicle intrusion was found to have a positive likelihood ratio of 0.889 for predicting trauma center need. According to current guidelines, these results suggest that VI criteria alone may not be an accurate predictor for trauma center transport and require further investigation.

BACKGROUND: The management of major liver trauma continues to evolve in trauma centers across the US with increasing use of minimally invasive techniques. Data on the outcomes of these procedures remain minimal. The objective of this study was to evaluate patient complications after perioperative hepatic angioembolization as an adjunct to management of major operative liver trauma. STUDY DESIGN: A retrospective multi-institutional study was performed at 13 level 1 and level 2 trauma centers from 2012 to 2021. Adult patients with major liver trauma (grade 3 and higher) requiring operative management were enrolled. Patients were divided into 2 groups: angioembolization (AE) and no angioembolization (NO AE). Univariate and multivariate analyses were performed. RESULTS: A total of 442 patients were included with AE performed in 20.4% (n = 90 of 442) of patients. The AE group was associated with higher rates of biloma formation (p = 0.0007), intra-abdominal abscess (p = 0.04), pneumonia (p = 0.006), deep vein thrombosis (p = 0.0004), acute renal failure (p = 0.004), and acute respiratory distress syndrome (p = 0.0003), and it had longer ICU and hospital length of stay (p < 0.0001). On multivariate analysis, the AE had a significantly higher amount intra-abdominal abscess formation (odds ratio 1.9, 95% CI 1.01 to 3.6, p = 0.05). CONCLUSIONS: This is one of the first multicenter studies comparing AE in specifically operative high-grade liver injuries and found that patients with liver injury that undergo AE in addition to surgery have higher rates of both intra- and extra-abdominal complications. This provides important information that can guide clinical management.

BACKGROUND: Rampage mass shootings (RMS) are a subset of mass shootings occurring in public involving random victims. Due to rarity, RMS are not well-characterized. We aimed to compare RMS and NRMS. We hypothesized that RMS and NRMS would be significantly different with respect to time/season, location, demographics, victim number/fatality rate, victims being law enforcement, and firearm characteristics. STUDY DESIGN: Mass shootings (4 or more victims shot at a single event) from 2014-2018 were identified in the Gun Violence Archive (GVA). Data were collected from the public domain (e.g. news). Crude comparisons between NRMS and RMS were performed using Chi-squared or Fisher's exact tests. Parametric models of victim and perpetrator characteristics were conducted at the event level using negative binomial regression and logistic regression. RESULTS: There were 46 RMS and 1626 NRMS. RMS occurred most in businesses (43.5%), whereas NRMS occurred most in streets (41.1%), homes (28.6%), and bars (17.9%). RMS were more likely to occur between 6AM-6PM (OR=9.0 (4.8-16.8)). RMS had more victims per incident (23.6 vs. 4.9, RR: 4.8 (4.3,5.4)). Casualties of RMS were more likely to die (29.7% vs. 19.9%, OR: 1.7 (1.5,2.0)). RMS were more likely to have at least one police casualty (30.4% versus 1.8%, OR: 24.1 (11.6,49.9)) or police death (10.9% versus 0.6%, OR: 19.7 (6.4,60.3)). RMS had significantly greater odds that casualties were adult (OR: 1.3 (1.0,1.6)) and female (OR: 1.7 (1.4,2.1)). Deaths in RMS were more likely to be female (OR: 2.0 (1.5,2.5)) and White (OR: 8.6 (6.2,12.0) and less likely to be children (OR: 0.4 (0.2,0.8)). Perpetrators of RMS were more likely to die by suicide (34.8%), be killed by police (28.3%), or be arrested at the scene (26.1%), while more than half of perpetrators from NRMS escaped without death or apprehension (55.8%). Parametric models of perpetrator demographics indicated significant increases in the odds that a RMS shooter was White (OR: 13.9 (7.3,26.6)) or Asian (OR: 16.9 (3.7,78.4)). There was no significant difference in weapon type used (p=0.35). CONCLUSION: The demographics, temporality, and location differ between RMS and NRMS, suggesting that they are dissimilar and require different preventive approaches.

A 26-year-old male presented to a Level 1 trauma center following a motorcycle crash. Workup of his injuries demonstrated a grade 5 liver laceration with active extravasation, grade 5 kidney laceration, right apical pneumothorax, and a sternal fracture. The patient underwent hepatic artery embolization with interventional radiology (IR) followed by an exploratory laparotomy, liver packing, and small bowel resection with primary anastomosis. Four days post-op, the patient developed dyspnea, tachycardia, and decreasing oxygen saturation. Computed tomography pulmonary angiography demonstrated perihepatic fluid compressing the right atrium and inferior vena cava. Percutaneous perihepatic drain placement with aspiration of 700 mL bilious fluid resulted in immediate resolution of the compression. He subsequently underwent endoscopic retrograde cholangiopancreatography (ERCP) with stenting of the ampulla nine days later. The patient was discharged ten days post-ERCP with oral amoxicillin/clavulanic acid for polymicrobial coverage and follow-up with gastroenterology and IR for stent removal and drain maintenance.

The coronavirus disease 2019 (COVID-19) pandemic is a slow-moving global disaster with unique challenges for maintaining trauma center operations. University Medical Center New Orleans is the only level 1 trauma center in New Orleans, LA, which became an early hotspot for COVID-19. Intensive care unit surge capacity, addressing components including space, staff, stuff, and structure, is important in maintaining trauma center operability during a high resource-strain event like a pandemic. We report management of the trauma center's surge capacity to maintain trauma center operations while assisting in the care of critically ill COVID-19 patients. Lessons learned and recommendations are provided to assist trauma centers in planning for the influx of COVID-19 patients at their centers.

BACKGROUND: Helicopter transport (HT) is an efficient, but costly, means for injured patients to receive life-saving, definitive trauma care. Identifying the characteristics of inappropriate HT presents an opportunity to improve the utilization of this finite medical resource. METHODS: Trauma registry records of all HT for a 3-year period (2016-2018) to an urban Level I trauma center were reviewed. HT was defined as inappropriate for patients who were discharged home from the emergency department or had a hospital length of stay <1 day, and who were discharged alive. Chi-square analysis and Student's t-test were used for univariate analysis. Predictors with a P value of less than .15 were subject to binary logistic regression analysis. A P value ≤.05 was considered significant. RESULTS: There were 713 patients who received HT during the study period. One-hundred and forty-eight (20.8%) patients met the criteria as an inappropriate HT. In univariate analysis, Glasgow Coma Scale >8, Shock Index <0.9, and fall mechanism were found to be significantly associated with inappropriate HT. Age >55 was found to be associated with an appropriate HT. The average Injury Severity Score of the inappropriate HT group was 3.86 (±3.85) compared with 16.80 (±11.23) (P = .0001, Student's t-test). DISCUSSION: Our findings suggest that there are evidence-based predictors of patients receiving inappropriate HT. Triage of HT using these predictors has the potential to decrease unnecessary deployments and reduce health care costs.

BACKGROUND: : Installation of red light cameras (RLC) at intersections associated with a high number of traffic accidents are currently in use to reduce the number of traffic collisions. The primary objective of this study was to evaluate the sustained effect of RLC on driver behavior. The secondary objective was to evaluate the number of collisions before and after RLC implementation. METHODS: : For the primary objective, an 8-month prospective observational study after installation of RLC in September 2007 was undertaken at the intersection with the highest incidence of traffic accidents in the State of Louisiana. For the secondary objective, collision occurrences were collected 10 months before and after RLC installation. The mean number of citations was calculated by month, and the statistical significance of trend was obtained from a linear regression model across the study period and by t test to compare before and after citations were issued. The number of traffic collisions was compared using chi. RESULTS: : During the initial 30 days, 2,428 violations per week were recorded, whereas in the subsequent 30 days, there were 534 citations per week issued (p < 0.001). After eight months, the number of citations was reduced to an average of 356 citations per week (p < 0.01). Mean number of citations decreased significantly during implementation of RLC. Three drivers received more than one citation. Although there was a trend in reduction of collisions from 122 to 97 before and after RLC, this did not reach statistical significance; p = 0.18. CONCLUSION: : A significant and sustained reduction in the number of citations occurred as driving behavior was modified. Despite reducing the number of cars entering this intersection during a red light, RLC do not seem to prevent traffic collisions at this monitored intersection. Alternative means of injury prevention must be investigated.

BACKGROUND: Damage control laparotomy (DCL) improves outcomes when used in patients with severe hemorrhage. Correction of coagulopathy with close ratio resuscitation while limiting crystalloid forms a new methodology known as damage control resuscitation (DCR). We hypothesize a survival advantage in DCL patients managed with DCR when compared with DCL patients managed with conventional resuscitation efforts (CRE). METHODS: This study is a 4-year retrospective study of all DCL patients who required >or=10 units of packed red blood cells (PRBC) during surgery. A 2-year period after institution of DCR (DCL and DCR) was compared with the preceding 2 years (DCL and CRE). Univariate analysis of continuous data was done with Student's t test followed by multiple logistic regression. RESULTS: One Hundred twenty-four and 72 patients were managed during the DCL and CRE and DCL and DCR time periods, respectively. Baseline patient characteristics of age, Injury Severity Score, % penetrating, blood pressure, hemoglobin, base deficit, and INR were similar between groups. There was no difference in quantity of intraoperative PRBC utilization between DCL and CRE and DCL and DCR study periods: 21.7 units versus 25.5 units (p = 0.53); however, when compared with DCL and CRE group, patients in the DCL and DCR group received less intraoperative crystalloids, 4.7 L versus 14.2 L (p = 0.009); more fresh frozen plasma (FFP), 18.2 versus 6.4 (p = 0.002); a closer FFP to PRBC ratio, 1 to 1.2 versus 1 to 4.2 (p = 0.002); platelets to PRBC ratio, 1:2.3 versus 1:5.9 (0.002); shorter mean trauma intensive care unit length of stay, 11 days versus 20 days (p = 0.01); and greater 30-day survival, 73.6% versus 54.8% (p < 0.009). The addition of DCR to DCL conveyed a survival benefit (odds ratio; 95% confidence interval: 0.19 (0.05-0.33), p = 0.005). CONCLUSION: This is the first civilian study that analyses the impact of DCR in patients managed with DCL. During the DCL and DCR study period more PRBC, FFP, and platelets with less crystalloid solution was used intraoperatively. DCL and DCR were associated with a survival advantage and shorter trauma intensive care unit length of stay in patients with severe hemorrhage when compared with DCL and CRE.

Charity Hospital (CH) was devastated by Hurricane Katrina and remains closed. Design and staffing of a new, temporary dedicated trauma hospital relied on data from prior experience at CH, updated census information, and a changed trauma demographic. The study objective was to analyze the new trauma program and evaluate changes in demographics, injury patterns, and outcomes between pre- (PK) and post-Katrina (POK) trauma populations. A retrospective review of trauma patients' demographics, anatomical variables, and physiological variables 6 months PK and POK was performed under an approved Institutional Review Board protocol. Trauma activation triage criteria between study periods were also analyzed. Continuous data comparisons between the two time periods were made with Student's t test. Dichotomous data were analyzed using chi2 test. The demographic of trauma patients is different in the POK interval, reflecting changes in the New Orleans population. Modification of triage criteria by the exclusion of mechanism as an activation criterion resulted in an increase of patients with higher acuity and Injury Severity Score, lower initial Glasgow Coma Score, and a higher proportion of penetrating mechanism. Outcome measures reflect longer length of stay (4.4 vs. 6.8 days, P < 0.0001) without a significant difference in mortality (6.0 vs 7.5, P = 0.227). Hospital data demonstrates that the POK trauma system was stressed by the increased acuity, penetrating injury, and number of procedures per patient (1.7 vs. 3.4). Resources should be directed toward patients requiring multidisciplinary care by increasing intensive care unit beds and operating room capacity. Future resource planning in the recovery phases of large-scale natural disasters should take into account these observations.

BACKGROUND: Although hemostatic resuscitation with a 1:1 ratio of fresh-frozen plasma (FFP) to packed red blood cells (PRBC) after severe hemorrhage has been shown to improve survival, its benefit in patients with traumatic-induced coagulopathy (TIC) after >10 units of PRBC during operation has not been elucidated. We hypothesized that a survival benefit would occur when early hemostatic resuscitation was used intraoperatively after injury in patients with TIC. METHODS: A 7-year retrospective study of patients with emergency department diagnosis of TIC after transfusion of >10 units of PRBC in the operating room. TIC was defined as initial emergency department international normalized ratio > 1.2, prothrombin time > 16 seconds, and partial thromboplastin time > 50 seconds. Patients were divided into FFP:PRBC ratios of 1:1, 1:2, 1:3, and 1:4. Patients with diagnosis of TIC who received transfusion of both FFP and PRBC during surgery were included. Other variables evaluated included age, gender, mechanism of injury, initial base deficit, mean operative time, trauma intensive care unit length of stay (TICU LOS) and Injury Severity Score. The primary outcome measure evaluated was the impact of the early FFP:PRBC ratio on mortality. RESULTS: Four hundred thirty-five patients underwent emergency operations postinjury and received FFP with >10 units of PRBC in the operating room; 135 (31.0%) of these patients had TIC and 53 died (39.5% mortality). Mean operative time was 137 minutes (SD +/- 49). There were no differences with regard to age, gender, mechanism of injury, initial base deficit, or Injury Severity Score among all groups. A significant difference in mortality was found in patients who received >10 units of PRBC when FFP:PRBC ratio was 1:1 versus 1:4 (28.2% vs. 51.1%, p = 0.03). Intermediate mortality rates were noted in patients with 1:2 and 1:3 ratios (38% and 40%, respectively). From a linear regression model, 13 days of increased TICU LOS was observed among 1:4 group compared with 1:1 group (p < 0.01). CONCLUSION: TIC is common after severe injury and is associated with a high mortality in patients transfused with >10 units of PRBC during surgery. Early hemostatic resuscitation during first hours after injury improves survival with shorter TICU LOS in patients with TIC.

Recombinant factor VII (rFVIIa) has arisen as an option for the control of life-threatening traumatic bleeding unresponsive to other means. The timing of administration, dosage, mortality, units of blood transfusion saved, risk of thrombotic events, and risk/benefits ratio are presently poorly defined. A Medline search from 1995 through March 2008 was conducted. All English language articles containing the terms "trauma" and "factor VII" or its variants were retrieved. Letters to the editor, animal studies, and general reviews were excluded. A total of 19 articles met inclusion criteria. These articles were then reviewed and stratified into three classes of evidence according to the quality assessment instrument developed by the Brain and Trauma Foundation. Levels of recommendation were developed. A total of 118 articles were identified. Only one Class I study was identified. This study demonstrated that three doses of rFVIIa given in blunt traumatic hemorrhage yielded a significant reduction of 2.6 of red blood cells used. These findings were not statistically significant for penetrating trauma patients. There was no reduction in mortality and no increase in thromboembolic events. Four Class II studies were identified; three showed a significant decrease of blood product usage and one demonstrated significant reductions in 24-hour and 30 day death from hemorrhage in patients receiving rFVIIa. The remaining 14 studies were Class III reviews of databases, registries, case series, and case reports. No identified study specifically addressed the cost/benefit analysis of rFVIIa usage in trauma hemorrhage. Utility of rFVIIa in trauma-associated hemorrhage remains controversial. There is Level I supporting the use of rFVIIa for blunt trauma patients only. There is no Class I evidence supporting decreased mortality or differences in thromboembolic events. Minimal effective dosing regimens and cost/benefit analyses have not yet been examined.

BACKGROUND: Recent military experience reported casualties who receive > 10 units of packed red blood cells (PRBC) in 24 hours have 20% versus 65% mortality when the fresh-frozen plasma (FFP) to PRBC ratio was 1:1 versus 1:4, respectively. We hypothesize a similar improvement in mortality in civilian trauma patients that require massive transfusion and are treated with a FFP to PRBC ratio closer to 1:1. METHODS: Four-year retrospective study of all trauma patients who underwent emergency surgery in an urban Level I Trauma Center. Patients were divided into two groups; those that received < or = 10 units or > 10 units of PRBC during and after initial surgical intervention. Only patients who received transfusion of both FFP and PRBC were included in the analysis. The primary research question was the impact of initial FFP:PRBC ratio on mortality. Other variables for analysis included patient age, gender, mechanism, and Injury Severity Scale score. Both univariate and multivariate analysis were used to assess the relationship between outcome and predictors. RESULTS: A total of 2,746 patients underwent surgical intervention of which 1,985 (72.2%) received no transfusion. Of those that received transfusion, 626 (22.8%) received < or = 10 units of PRBC and 135 (4.9%) > 10 units of PRBC. Out of the 626 patients that received < or = 10 units of PRBC, 250 (39.9%) received FFP and 376 (60.1%) received no FFP. All the patients that received > 10 units PRBC received FFP. In univariate analysis, a significant difference in mortality was found in patients who received > 10 units of PRBC (26% vs. 87.5%) when FFP:PRBC ratio was 1:1 versus 1:4 (p = 0.0001). Multivariate analysis in the group of patients that received > 10 units of PRBC showed a FFP:PRBC ratio of 1:4 was consistent with increased risk of mortality (relative risk, 18.88; 95% CI, 6.32-56.36; p = 0.001), when compared with a ratio of 1:1. Patients who received < or = 10 units of PRBC had a trend toward increased mortality (21.2% vs.11.8%) when the FFP:PRBC ratio was 1:4 versus 1:1 (p: 0.06). CONCLUSION: An FFP to PRBC ratio close to 1:1 confers a survival advantage in patients requiring massive transfusion.

BACKGROUND: The purpose of this study was to compare disaster preparedness of a Level I Trauma Center with performance in an actual disaster. Previous disaster response evaluations have shown that the key to succeeding in responding to a catastrophic event is to anticipate the event, plan the response, and practice the plan. The Emergency Management Team had identified natural disaster as the hospital's highest threat. The hospital also served as the regional hospital for the Louisiana Health Resources and Service Administration Bioterrorism Hospital Preparedness Program. METHODS: The hospital master disaster plan, including the Code Gray annex, was retrospectively reviewed and compared with the actual events that occurred after Hurricane Katrina. Vital support areas were evaluated for adequacy using a systematic approach. In addition, a survey of 10 key personnel from trauma and emergency medicine present during Hurricane Katrina was conducted. The survey of vital support areas were scored as adequate (3 pts), partially adequate (2 pts), or inadequate (1 pt). RESULTS: Ninety-three percent of the line items on the Code Gray Checklist were accomplished before landfall of the storm. The results of the survey of vital support areas were water-3.0, food-2.4, sanitation-1.5, communication-1.4, and power-1.5. CONCLUSION: Despite identifying the threat of a major hurricane, preparing a response plan, and exercising the plan, a major medical center can be overwhelmed by a catastrophic disaster like Hurricane Katrina. We offer our lessons-learned as an aid for other medical centers that are developing and exercising their plans.
