Friday classes, and a 54% decrease following onset of the 21-Only Ordinance (p<0.02 when comparing interventions). Among UIstudents, 31% and 53% decreases were seen, respectively (p<0.01 when comparing semesters). Conclusion: Further research is indicated to effectively study correlations between alcohol-related ED visits and alcoholinterventions, as retrospective studies cannot provide direct causation for observed changes. Observed differences between male and female incidence and mechanism of injury may warrant future interventions and educational means that are gender-specific. 13. Short QTc in Emergency Department Patients Stacey House, Peta-Gay Laird and S. Eliza Halcomb. Washington University in St. Louis, St. Louis, MO Background: A short QTc interval has been shown to predispose patients to arrhythmias and sudden death. Electrolyte abnormalities, hyperthermia, and some medications are associated with shortened QTc. As the importance of short QTc has only recently been appreciated, there is limited literature describing patients with short QTc especially in the ED. Objectives: The study objective was to characterize the ED population with short QTc. Methods: This study was a retrospective review of ED patients (pts) who received an ECG from April - September 2009 at a large volume, tertiary care center. Inclusion criteria were pts with a QTc≤390ms. Exclusion criteria included pts with an ECG showing bradycardia (HR<60bpm), tachycardia (HR>100bpm), QRS>120ms, or non-sinus rhythm. ED electronic medical records were reviewed for multiple comorbid conditions, presenting symptoms, electrolyte abnormalities, medications, and disposition. Results: 13,494 pts received ECGs during the six month period. Of these, 281 had a QTc≤390ms (2%, 95%CI 1.8-2.3%). 136 were excluded, leaving 145 eligible pts. Of these, 108 (75%) had a QTc 380-390ms, 26 (18%) had a QTc 370-379ms, and 10 (7%) had a QTc≤369ms. These pts were 39±2 years old and were predominantly male (71%, 95%CI 63-78%). Hypertension (22%), psychiatric conditions (17%), and drug abuse (22%) were the most common comorbidities. The most common symptoms were chest pain (56%), shortness of breath (40%), and dizziness (19%). 18% (95%CI 1025%) had abnormal serum potassium, and 13% (95%CI 6-19%) had abnormal serum calcium. 4% (95CI 1-7%) were hyperthermic. Only 3% (95%CI 1-5%) were on home medications which shortened QTc interval including <1% on digoxin, the most commonly described cause of medication-induced short QTc. 70% (95%CI 63-78%) were discharged from the ED. There were no significant differences among the different length QTc groups with regards to comorbidities, symptoms, electrolyte abnormalities, QTc shortening medications, or disposition. Conclusion: Shortened QTc occurs in 1-2% of ED pts with <0.1% having a QTc<369ms. Even though hypercalcemia, hyperthermia, and digoxin therapy are commonly reported causes of shortened QTc, a very small portion of ED pts with shortened QTc had these findings. As the majority of these pts are discharged from the ED, further studies are needed to determine the cardiac event rates in ED pts with shortened QTc. 14. Data Based on All-terrain Vehicle (ATV) Crash Site Informs Rural Health and Safety Policy Gerene M Denning, Kari Harland, Kevin Kremer, Charles Jennissen and Christopher Buresh. University of Iowa, Iowa City, IA Background: Every year, U.S. ATV crashes result in over 500 deaths, 130,000 ED visits, and $4 billion in lost life and healthcare costs. One in three victims are under the age of 16. Because the vast majority of ATV crashes occur in or near rural communities, they represent a serious threat to rural health and safety. Objectives: The objectives of this project were to compare Iowa ATV crashes by crash location, and to develop public policy recommendations based on these results. Methods: Data for these studies were generated from our Iowa ATV Injury Surveillance Database (2002-2009). Proportions were compared using the chi-square test. Injury severity scores for on and off-road crashes were compared using the Mann-Whitney test. Results: Females (23%) and children under sixteen (32%) were a higher percentage of on-road crash victims as compared to crashes in Off-Highway Vehicle (OHV) parks (females, 8%; children 10%; p < 0.05). There were also significantly higher proportions of on-road (17%) and off-road (15%) crashes that involved passengers, when compared to crashes in the parks (3.8%, p < 0.05). Monitoring and enforcement of helmet requirements in the parks appeared to increase helmet use (91%) relative to other sites (on-road, 13%; off-road, 25%; p < 0.0001); Iowa does not currently have a statewide helmet law. On-road crashes were 8-fold more likely to involve a collision with another vehicle relative to off-road crashes. On-road fatalities averaged two per year, whereas a single fatality was recorded in the parks over the 8-year period. Injury severity scores were higher for on-road crashes relative to off-road locations (p < 0.0001), and victims from on-road crashes were 3 times more likely to suffer traumatic brain injury relative to off-road victims. Conclusion: Iowa law allows cities and counties to designate streets/roads for general ATV use; however, our data indicate that onroad ATV crashes pose a serious injury risk and traffic safety hazard. Based on these findings, we would strongly advise policy makers against increasing ATV road use. Conversely, enforcement of OHV park regulations, including no passenger rules and required helmet use, appears to promote safer behaviors and better outcomes. Expanding safe, controlled places for recreational riding would be a potential way to reduce ATV-related deaths and injuries. 15. A Comparison of Two Hospital Electronic Medical Record Systems and Their Effects on the Relationship Between Physician Charting and Patient Contact John Shabosky, Jonathan dela Cruz and Matthew Albrecht. Southern Illinois University School of Medicine, Springfield, IL Background: Recent health care reform has placed an emphasis on the electronic health record (EHR). With the advent of the EHR it is common to see ED providers spending more time in front of computers documenting and away from patients. Finding strategies to decrease provider interaction with computers and increase time with patients may lead to improved patient outcomes and satisfaction. Computerized charting adjuncts, such as voice recognition software, have been marketed as ways to improve provider efficiency and patient contact. Objectives: We present here observational data comparing two separate ED sites, one where computerized charting is done by conventional techniques and one that is assisted with voice recognition dictation, and their effects on physican charting and patient contact. Methods: A prospective observational quality initiative was conducted at two teaching hospitals located less than 1 mile from each other. One site primarily uses conventional computerized charting while the other uses voice recognition dictation. Four trained quality assistants observed ED physicians for 180 minutes during shifts. The tasks each physician performed were noted and logged in 30 second intervals. Tasks listed were identified from a predetermined standardized list presented at observer training. A total of 4140 minutes were logged. Time allocated to charting and that allocated to direct patient care were then compared between sites.
