Predictors of Nondiagnostic Ultrasound for Appendicitis. journal of emergency medicine Keller, C., Wang, N. E., Imler, D. L., Vasanawala, S. S., Bruzoni, M., Quinn, J. V. 2016


Ionizing radiation and cost make ultrasound (US), when available, the first imaging study for the diagnosis of suspected pediatric appendicitis. US is less sensitive and specific than computed tomography (CT) or magnetic resonance imaging (MRI) scans, which are often performed after nondiagnostic US.We sought to determine predictors of nondiagnostic US in order to guide efficient ordering of imaging studies.A prospective cohort study of consecutive patients 4 to 30years of age with suspected appendicitis took place at an emergency department with access to 24/7 US, MRI, and CT capabilities. Patients with US as their initial study were identified. Clinical (i.e., duration of illness, highest fever, and right lower quadrant pain) and demographic (i.e., age and sex) variables were collected. Body mass index (BMI) was calculated based on Centers for Disease Control and Prevention criteria; BMI >85th percentile was categorized as overweight. Patients were followed until day 7. Univariate and stepwise multivariate logistic regression analysis was performed.Over 3months, 106 patients had US first for suspected appendicitis; 52 (49%) had nondiagnostic US results. Eighteen patients had appendicitis, and there were no missed cases after discharge. On univariate analysis, male sex, a yearly increase in age, and overweight BMI were associated with nondiagnostic US (p<0.05). In the multivariate model, only BMI (odds ratio 4.9 [95% CI 2.0-12.2]) and age (odds ratio 1.1 [95% CI 1.02-1.20]) were predictors. Sixty-eight percent of nondiagnostic US results occurred in overweight patients.Overweight and older patients are more likely to have a nondiagnostic US or appendicitis, and it may be more efficient to consider alternatives to US first for these patients. Also, this information about the accuracy of US to diagnose suspected appendicitis may be useful to clinicians who wish to engage in shared decision-making with the parents or guardians of children regarding imaging options for children with acute abdominal pain.

Development of DASH Mobile: A mHealth Lifestyle Change Intervention for the Management of Hypertension MEDINFO 2013: PROCEEDINGS OF THE 14TH WORLD CONGRESS ON MEDICAL AND HEALTH INFORMATICS, PTS 1 AND 2 Mann, D. M., Kudesia, V., Reddy, S., Weng, M., Imler, D., Quintiliani, L. 2013; 192: 973-973


Several landmark studies based on the DASH diet have established the effectiveness of a lifestyle approach to blood pressure control that emphasizes a diet rich in fruits and vegetables with moderate portions of low-fat dairy and lean protein along with increased physical activity and reduced sodium intake. However, this evidence base remains underused due feasibility limitations of implementing these intense in-person interventions and poor engagement with desktop computer based versions. Mobile technologies such as smartphones and wireless sensors have the ability to deliver behavioral interventions in-the-moment and with reduced user burden. DASH Mobile is a new mHealth system being developed to deliver this evidence-based lifestyle intervention to hypertensive patients. The system consists of an Android based "app" that facilitates easy tracking of DASH food portions, integrated Bluetooth blood pressure, weight and pedometer monitoring, goal setting, simple data visualizations and multimedia video clips to train patients in the basic concepts of the lifestyle change plan. At present, the system is undergoing usability testing with a pilot clinical trial planned for Spring 2013.

Improved physician work flow after integrating sign-out notes into the electronic medical record. Joint Commission journal on quality and patient safety / Joint Commission Resources Bernstein, J. A., Imler, D. L., Sharek, P., Longhurst, C. A. 2010; 36 (2): 72-78


In recent years, electronic sign-out notes have been identified as a means of enhancing the effective transfer of patient care between providers. Such a tool was developed and implemented within the electronic medical record (EMR) system, and its impact on physician work flow was assessed.A printable sign-out report was implemented within the EMR system at a tertiary academic children's hospital. Month 1 post go-live survey data were collected in June and July 2006, and 6-month post go-live survey data were collected in November and December 2006. Use of the sign-out form to document handoff data between go-live and Month 16 (September 2007) was measured using log data from the EMR. Housestaff physicians were asked to report the impact of the tool on their work flow and satisfaction with the sign-out process through a Web-based survey.The sign-out report was steadily adopted following its introduction. Between the first and second surveys, use of EMR-integrated sign-out increased from 37% to 81% of respondents for day-to-night sign-out (chi2 = 12.79, p < .001) and from 14% to 39% for night-to-day sign-out (chi 2 = 5.08, p < .05). With increased use of the report, housestaff reported less time devoted to redundant data entry and increased satisfaction with the sign-out process.EMR-integrated sign-out documents offer the advantages of other electronic network-accessible systems and can also incorporate information already in the medical record in an automated manner. Although the primary motivation for introducing standardized, EMR-integrated sign-out documents is to enhance the safety of patient handoffs, the perception of improved physician work flow is also a benefit of such an intervention.
