Race/ethnicity and gender differences in drug use and abuse among college students

This study examines race/ethnicity and gender differences in drug use and abuse for substances other than alcohol among undergraduate college students. A probability-based sample of 4,580 undergraduate students at a Midwestern research university completed a cross-sectional Web-based questionnaire that included demographic information and several substance use measures. Male students were generally more likely to report drug use and abuse than female students. Hispanic and White students were more likely to report drug use and abuse than Asian and African American students prior to coming to college and during college. The findings of the present study reveal several important racial/ethnic differences in drug use and abuse that need to be considered when developing collegiate drug prevention and intervention efforts.https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2377408/https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2377408/Accepted manuscrip

Program Director Opinion on the Ideal Length of Residency Training in Emergency Medicine

ObjectiveThis study sought to define expert opinion on the ideal length of training (LoT) for Accreditation Council of Graduate Medical Education (ACGME)‐accredited emergency medicine (EM) residency programs.MethodsA cross‐sectional Web‐based survey was sent to program directors (PDs) at all ACGME‐accredited EM residency programs during a study period of August to October 2014. The primary outcome of ideal LoT was determined in two ways: 1) subjects provided the ideal total LoT in months and 2) then separately selected the type and number of rotations for an ideal EM residency curriculum by month, the sum of which provided an alternative measurement of their ideal LoT. We did not include vacation time. Descriptive statistics and an analysis of variance are reported.ResultsResponse rate was 68.0% (108/159) with 72% of respondents (78/108) directing programs in the PGY 1–3 (36‐month) format and 28% directing PGY 1–4 (48‐month) programs. More than half of subjects (51.9%) have direct personal experience with both formats. When asked about ideal total LoT, PDs averaged 41.5 months (n = 107; SD = 5.5 months, range = 36–60 months). When asked to provide durations of individual clinical experiences for their ideal EM program, the sum total (n = 104) averaged 45.0 months. Results from a factorial analysis of variance revealed statistically significant effects of PDs’ past training experiences: participants who trained in a 36‐month program had statistically significantly lower LoT (mean = 39.2 months) than participants who trained in a 48‐month program (mean = 44.5 months). There was also a statistically significant effect of current program format on ideal LoT: participants who directed a 36‐month program had statistically significantly lower LoT (mean = 39.8 months) than participants who directed a 48‐month program (mean = 45.8 months).ConclusionsPD opinion on ideal LoT averages between 36 and 48 months, but is longer when the sum of desired clinical rotations is considered. While half of the respondents reported direct experience with both PGY 1–3 and PGY 1–4 training programs, opinions on ideal LoT through both methods corresponded strongly with the length of the program the PDs trained in and the format of the program they currently direct. PD opinions may be too biased by their own experiences to provide objective input on the ideal LoT for EM residency programs.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/133574/1/acem12968-sup-0001-DataSupplementS1.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/133574/2/acem12968.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/133574/3/acem12968_am.pd

Comparison of the Standardized Video Interview and Interview Assessments of Professionalism and Interpersonal Communication Skills in Emergency Medicine

ObjectivesThe Association of American Medical Colleges Standardized Video Interview (SVI) was recently added as a component of emergency medicine (EM) residency applications to provide additional information about interpersonal communication skills (ICS) and knowledge of professionalism (PROF) behaviors. Our objective was to ascertain the correlation between the SVI and residency interviewer assessments of PROF and ICS. Secondary objectives included examination of 1) inter‐ and intrainstitutional assessments of ICS and PROF, 2) correlation of SVI scores with rank order list (ROL) positions, and 3) the potential influence of gender on interview day assessments.MethodsWe conducted an observational study using prospectively collected data from seven EM residency programs during 2017 and 2018 using a standardized instrument. Correlations between interview day PROF/ICS scores and the SVI were tested. A one‐way analysis of variance was used to analyze the association of SVI and ROL position. Gender differences were assessed with independent‐groups t‐tests.ResultsA total of 1,264 interview‐day encounters from 773 unique applicants resulted in 4,854 interviews conducted by 151 interviewers. Both PROF and ICS demonstrated a small positive correlation with the SVI score (r = 0.16 and r = 0.17, respectively). ROL position was associated with SVI score (p < 0.001), with mean SVI scores for top‐, middle‐, and bottom‐third applicants being 20.9, 20.5, and 19.8, respectively. No group differences with gender were identified on assessments of PROF or ICS.ConclusionsInterview assessments of PROF and ICS have a small, positive correlation with SVI scores. These residency selection tools may be measuring related, but not redundant, applicant characteristics. We did not identify gender differences in interview assessments.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/150548/1/aet210346_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/150548/2/aet210346.pd

Cardiopulmonary ultrasound for critically ill adults improves diagnostic accuracy in a resourceâ limited setting: the AFRICA trial

ObjectiveTo assess the effects of a cardiopulmonary ultrasound (CPUS) examination on diagnostic accuracy for critically ill patients in a resourceâ limited setting.MethodsApproximately half of the emergency medicine resident physicians at the Komfo Anokye Teaching Hospital (KATH) in Kumasi, Ghana, were trained in a CPUS protocol. Adult patients triaged to the resuscitation area of the emergency department (ED) were enrolled if they exhibited signs or symptoms of shock or respiratory distress. Patients were assigned to the intervention group if their treating physician had completed the CPUS training. The physician’s initial diagnostic impression was recorded immediately after the history and physical examination in the control group, and after an added CPUS examination in the intervention group. This was compared to a standardised final diagnosis derived from post hoc chart review of the patient’s care at 24 h by two blinded, independent reviewers using a clearly defined and systematic process. Secondary outcomes were 24â h mortality and use of IV fluids, diuretics, vasopressors and bronchodilators.ResultsOf 890 patients presenting during the study period, 502 were assessed for eligibility, and 180 patients were enrolled. Diagnostic accuracy was higher for patients who received the CPUS examination (71.9% vs. 57.1%, Î 14.8% [CI 0.5%, 28.4%]). This effect was particularly pronounced for patients with a â cardiacâ diagnosis, such as cardiogenic shock, congestive heart failure or acute valvular disease (94.7% vs. 40.0%, Î 54.7% [CI 8.9%, 86.4%]). Secondary outcomes were not different between groups.ConclusionsIn an urban ED in Ghana, a CPUS examination improved the accuracy of the treating physician’s initial diagnostic impression. There were no differences in 24â h mortality and a number of patient care interventions.ObjectifEvaluer les effets de l’examen échographique cardioâ pulmonaire (CPUS) sur la précision du diagnostic chez les patients gravement malades dans un cadre à ressource limitée.MéthodesEnviron la moitié des médecins résidents en médecine d’urgence à la Komfo Anokye Teaching Hôpital (KATH) à Kumasi, au Ghana ont été formés pour un protocole de CPUS. Les patients adultes triés dans l’unité de ressuscitation des soins intensifs ont été inscrits s’ils présentaient des signes ou des symptômes de choc ou d’une détresse respiratoire. Les patients ont été assignés au groupe d’intervention si leur médecin traitant avait suivi la formation CPUS. Le diagnostic initial du médecin a été enregistré immédiatement après l’anamnèse et l’examen physique dans le groupe témoin, et après un examen CPUS ultérieur dans le groupe d’intervention. Cela a été comparé à un diagnostic final standard dérivé de l’analyse postâ hoc en aveugle des dossiers de soins du patient à 24 heures par deux examinateurs indépendants, au moyen d’un processus clairement défini et systématique. Les résultats secondaires étaient la mortalité de 24 heures et l’utilisation de fluides en IV, de diurétiques, de vasopresseurs et de bronchodilatateurs.RésultatsSur 890 patients présentés au cours de la période dâ étude, 502 ont été évalués pour lâ éligibilité et 180 patients ont été inscrits. La précision du diagnostic était plus élevée chez les patients ayant reçu l’examen CPUS (71,9% contre 57,1%, Î 14,8% [IC: 0,5% à 28.4%]). Cet effet était particulièrement marquée pour les patients avec un diagnostic «cardiaque», tel que le choc cardiogénique, l’insuffisance cardiaque congestive ou une maladie aiguë valvulaire (94,7% contre 40,0%, Î 54,7% [IC: 8,9% à 86,4%]). Les résultats secondaires nâ étaient pas différents entre les groupes.ConclusionsDans un service de soins intensifs urbain au Ghana, un examen CPUS améliorait la précision du diagnostic initial du médecin traitant. Il n’y avait aucune différence dans la mortalité de 24 heures et dans le nombre des interventions de soins.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/141626/1/tmi12992.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/141626/2/tmi12992_am.pd

Determination of freedom-from-rabies for small Indian mongoose populations in the United States Virgin Islands, 2019–2020

Mongooses, a nonnative species, are a known reservoir of rabies virus in the Caribbean region. A cross-sectional study of mongooses at 41 field sites on the US Virgin Islands of St. Croix, St. John, and St. Thomas captured 312 mongooses (32% capture rate). We determined the absence of rabies virus by antigen testing and rabies virus exposure by antibody testing in mongoose populations on all three islands. USVI is the first Caribbean state to determine freedom-from-rabies for its mongoose populations with a scientifically-led robust cross-sectional study. Ongoing surveillance activities will determine if other domestic and wildlife populations in USVI are rabies-free
