Background: Breath analysis for the presence of alcohol hasbecome an indispensible part of law enforcement as a means ofscreening for acute alcohol intoxication. There are no studiesdetermining the effect of commonly available breath sprays onportable breath testers (PBT).Objectives: This study was designed to test a protocol fordetermining the effect of these breath sprays on PBTs. CurrentU.S. Department of Transportation (DOT) guidelines and our PBToperations manual require that subjects be observed for 15 min-utes prior to a PBT test being performed if the test is to be admis-sible in court.Methods: A total of five commonly available breath sprayswere purchased from a national chain drug store. Five subjectswere recruited and refrained from alcohol for 24 hours prior tothe test. Using the manufacturer’s operations manual, a LifelocTechnologies FC10 PBT was used to collect initial samples. Eachsubject sprayed five sprays into his or her mouth and immediatelyexhaled into the mouthpiece. This initial reading was recorded anda timer started. The subject was then asked to breathe through thenose and exhale only through the mouth. Samples were obtainedfrom the subject until the PBT registered no alcohol, at which timethe time was recorded. Each subject repeated this protocol oneach of the five breath sprays. Subjects were given a brief breakbetween testing sessions while the other subjects were tested, butthey were not permitted to eat or drink anything other than water.Results: During the first exhalation, all five breath sprays regis-tered at the maximum reading of >0.6 blood alcohol concentration.Breath sprays no longer registered at a mean ranging from 4 min-utes to 5 minutes 30 seconds.Conclusions: All five breath sprays were eliminated from thesubjects’ breath well before the U.S. DOT observation period has

elapsed. This protocol was made using mouth exhalations. We donot know the impact that nasal-only breathing would have on theclearance of the breath sprays.

Objectives: Increasing size of medical school classes hasresulted in the use of community hospitals for emergency medicine(EM) clerkships. While differences in clinical experience areexpected, it is unclear if they are significant. The authors set out toinvestigate whether or not clinical site affects student learningusing end of clerkship examination score as a marker.Methods: This was a retrospective analysis of data from 2003–2009 for a mandatory fourth-year EM clerkship at one institution

that uses academic (EM residency), hybrid (residency training sitebut not EM), and community hospitals as clerkship sites. Multiplevariable linear regression was used to examine the relationshipbetween clerkship site (academic vs. hybrid vs. community) andend of clerkship written exam score. The authors also examinedthe following secondary variables: time of year rotation was com-pleted (by three-month tertiles) and whether the student matchedin EM. As test scores globally increased over the study period, atime factor was also included to account for this secular trend.Results: A total of 1,084 students completed the clerkship andhad complete data for analysis. Factors associated with higher testscore were student match in EM (beta coefficient 2.97, 95% confi-dence interval [CI] = 0.69 to 5.26), completing clerkship in July–September (beta coefficient 2.46, 95% CI = 1.23 to 3.69), and lateryear during the study period (beta coefficient 1.27, 95% CI = 1.18to 1.37). Clinical site was not a significant predictor of exam per-formance. No significant interaction terms were identified.Conclusions: The authors found no evidence that clerkshiplocation affected final exam score. Academic EM clerkships mayconsider partnering with other hospitals for educational venueswithout compromising education.
