Objective: Many clinicians are well aware that a golden hourexists for the use of thrombolytics in stroke patients. Conse-quently, some have been reporting that pre-hospital delay isone of the major causes of delayed treatment beyond 3 h andthat a definite pre-hospital delay happens in some restricted re-gions of Korea. To the best of our knowledge, no studies havereported on the geographic diversity of stroke care in Korea.We therefore evaluated whether Emergency Medical Services(EMS) transportation differs depending on area, using a motionchart supported by Google, and then we used a funnel plot to de-termine if geographic differences are significant. Methods: Weobtained data from the ‘‘Emergency Medicine Annual Report’’published by the National Emergency Medical Center in Korea.We were able to construct a motion chart showing the percent-age of therapeutically eligible stroke patients against the volumeof total visiting patients according to area for the previous fewyears. We plotted these data as a funnel plot, which is a well-known statistical control chart that shows warning and controllimits. Results: The motion chart clearly revealed some areaswith a poor quality of EMS transportation over a few years.The funnel plot showed that four areas out of 16 political dis-tricts in Korea are across a control limit and one area is withina warning and control limit. Conclusions: Our analysis indicatesthat several areas need to be investigated carefully, becausethose areas have a low percentage of therapeutically eligiblestroke patients when compared with a similar volume of visitingpatients at EDs across Korea. So the use of control charts, suchas motion charts and funnel plots, could also improve the qualityof several medical fields in addition to treatment of strokepatients.

, AN EVALUATION OF A MASS-CASUALTY IN-CIDENT WHICH DEVELOPED AFTER A BUS FELLOFF THE INCHEON BRIDGE. S. Kang, H. M. Jung,S. H. Yun, J. H. Kim, S. B. Han, J. S. Kim, J. H. Paik,Emergency Medicine, Inha University Hospital, Incheon,KOREA.

Objective: Field triage, medical care, and transportation areimportant and life-saving medical tasks performed at the site ofmass-casualty incidents (MCIs). We investigated the MCI of anexpress bus that fell off the Incheon bridge and evaluated prob-lems. We are willing to provide information for equipping andlocal disaster planning. Methods: We surveyed the local emer-gency medical system response time, transportation time, andpatients’ clinical data from paramedic and hospital medical re-cords. We assess the adequacy of triage, field medical care, andtransportation. Results: Twenty-four people who were on thebus were evacuated. Sixteen patients (66.7%) were transportedto one hospital; 12 persons were dead on the scene. There wastransport delay in living patients because transportation of thedead was carried out early. Advanced airway and vascular assesswere not performed on any patients. Conclusions: When we

reviewed these MCIs, there was no appropriate medical controlsuch as triage and transportation. In the construction of emer-gency medical service system preparing MCIs or disasters, wesuggest the integration and unification of 119 rescue servicesand emergency medical information centers for effective medi-cal control. Disaster drills should be performed with the guide-line of local emergency medical services.

, THE EFFECT OF HURRICANE KATRINA ON VIO-LENCE AGAINST WOMEN IN ORLEANS PARISH.L. Moreno-Walton, J. Avegno, B. Lee, Emergency Medicine,Louisiana State University Health Sciences Center, NewOrleans, LA, I. Espinal, General Studies, Oberlin College,Oberlin, OH.

Objective: To compare sexual assault rates, severity, andcharacteristics pre- and post-Hurricane Katrina (K). Methods:Retrospective chart review for the 5-year periods pre- andpost-K examining rates and parameters of severity. Pearson’schi-squared test was used for categorical data; Wilcoxon ranktest for non-parametric data. Odds ratios (OR) werecalculated. Results: Victims were younger pre-K (p = 0.0139).Women who were assaulted post-K were less likely to be black;OR 0.44, 95% confidence interval (CI) 0.3652–0.5364; morelikely to test positive for drugs, OR 1.75 95% CI 1.4271–2.1425, (p# 0.0001); less likely to have suffered trauma, OR0.65 95% CI 0.5382–0.7898, (p# 0.0001). Women who wereassaulted pre-K were more likely to have known the assailant,OR 0.79, 95% CI 0.6489–0.97474, p < 0.0001. Conclusions:Despite the correlation between disasters and increased ratesand severity of trauma towomen discussed in the literature, Hur-ricane Katrina had no such effect.

Objective: Sudden cardiac death is often fatal, and themajor-ity of out-of-hospital cardiac arrest (OHCA) studies have beenconducted as retrospective or individual prospective studies.This study was based on a national prospective registry entitled‘‘Research on the Actual State of OHCA in Korea,’’ which wasconducted by the NEDIS-CA (National Emergency DepartmentInformation System for Cardiac Arrest) consortium. This is thefirst national Web-based prospective, multicenter study to be
