TRANSCRIPT
Poster Print Size: This poster template is 50” high by 30” wide and is printed at 120% for a 60” high by 36” wide poster. It can be used to print any poster with a 5:3 aspect ratio.
Placeholders: The various elements included in this poster are ones we often see in medical, research, and scientific posters. Feel free to edit, move, add, and delete items, or change the layout to suit your needs. Always check with your conference organizer for specific requirements.
Image Quality: You can place digital photos or logo art in your poster file by selecting the Insert, Picture command, or by using standard copy & paste. For best results, all graphic elements should be at least 150-200 pixels per inch in their final printed size. For instance, a 1600 x 1200 pixel photo will usually look fine up to 8“-10” wide on your printed poster.
To preview the print quality of images, select a magnification of 100% when previewing your poster. This will give you a good idea of what it will look like in print. If you are laying out a large poster and using half-scale dimensions, be sure to preview your graphics at 200% to see them at their final printed size.
Please note that graphics from websites (such as the logo on your hospital's or university's home page) will only be 72dpi and not suitable for printing.

Critical to Quality (CTQ) Tree
Results of the identified “vital few” measures: The height documentation non-compliance rate decreased from 51.49% to 26.85% (a decrease of 47.85%, P = 0.001) and the sigma level was improved from 1.46 to 2.12. The BMI documentation non-compliance rate decreased from 50% to 18.79% (a decrease of 62.42%, P = 0.000) and the sigma level was improved from 1.5 to 2.39. The weight documentation non-compliance rate decreased from 39.55 % to 22.15% (a decrease of 43.99%, P = 0.002) and the sigma level was improved from 1.76 to 2.27.

Problem Statement: The United States Preventive Services Task Force (USPSTF) recommends that clinicians should screen all adult patients aged ≥18 years for obesity. Obese patients determined by a body mass index (BMI) of 30kg/m2 or higher should be managed with various interventions. In the 2013 academic year, our single internal medicine resident clinic located in an urban academic medical center in Washington, D.C. was only 50% compliant with BMI documentation. Moreover, there was non-compliance with several other measures related to total obesity management. Aim Statement: Decrease the non-compliance rates of the identified “vital few” measures related to obesity management of patients seen in the resident clinic by 30% over a four-month period. Interdisciplinary Team: Clinic attending physician who is a certified Six Sigma Black Belt , resident physicians, triage nurses and clinic manager.

D.M.A.I.C Model of Six Sigma
Utilization of the DMAIC methodology of six sigma led to significant improvement in obesity screening in a resident continuity clinic of an urban academic medical center.
Effectiveness 1: Not very effective
5: Very effective
Feasibility 1 (low): Expensive & difficult to implement 5 (high): Inexpensive & easy to implement

Effectiveness & Feasibility Matrix of Actions Taken
Pareto analysis of obesity management non-compliance The obesity epidemic in the United States has reached an all time high. Studies have shown that approximately 66% of Americans are overweight or obese. Of major concern is the rate of obesity in Washington, D.C. which is the 2nd highest in the country. Obesity has been shown to be directly correlated to chronic diseases such as diabetes mellitus type 2, asthma, heart disease, stroke, and some cancers. In Washington, D.C., 5 of the top 10 causes of death are directly related to diet, physical activity, and weight status. Due to these associations, obesity has health, economic, and psychosocial consequences.
Unfortunately, minority populations and those of low socioeconomic status are disproportionately impacted by obesity. Obesity is significantly higher in African-American and Latino communities compared to Caucasian populations. In 2012, 9.6 % of Caucasian D.C. residents were obese, while 33.7% of blacks were obese. Our urban academic medical center caters to a mostly African-American population.
