3087 US trends in diet and exercise counseling for patients with and without diabetes: The National Ambulatory Medical Care Surveys, 2005-2015

OBJECTIVES/SPECIFIC AIMS: Type 2 diabetes (T2D) is costly and burdensome, but strong evidence exists that lifestyle change and weight loss can improve glycemic control and lower co-morbidities for patients with T2D. We used national data to examine whether the frequency of diet and/or physical activity counseling for patients with T2D in ambulatory settings has been responsive to accumulation of evidence supporting lifestyle change. METHODS/STUDY POPULATION: We used National Ambulatory Medical Care Survey (NAMCS) data over the period 2005-2015 from 31,475 patients with provider-reported T2D. We built multivariate logistic regression models, adjusting for patient, provider, and practice level characteristics (i.e. patient demographics, physician specialty, site of care, and region), to assess changes over time in the provision of diet or exercise counseling during ambulatory care visits, as reported through provider/staff chart review. We also examined whether changes in counseling over time varied by key patient and provider characteristics. We used non-overlapping confidence intervals (CI) to assess for statistical significance. RESULTS/ANTICIPATED RESULTS: Proportions of patients with T2D who received diet or exercise counseling were no different over time: 30% in 2005 [95% CI: 25%-35%] and 25% in 2015 [95% CI: 18%-31%]. Adjusted models show Hispanic patients had higher likelihood of receiving diet or exercise counseling, compared to whites (OR: 1.38 [CI: 1.03-1.85] for diet; OR: 1.37 [CI: 1.01-1.85] for exercise), and younger age was associated with higher likelihood of diet or exercise counselling, compared to those over 75 (age 30-49, OR: 1.47 [CI:1.18-1.82] for diet OR: 1.63 [CI: 1.30-2.03] for exercise). Among provider and practice-level characteristics, metro area and type of provider were associated with higher odds of receiving any diet and/or exercise counseling with visits in a metro area (OR: 1.23 [CI: 1.03-1.48]) and with an advanced practice provider (OR: 1.77 [CI: 0.97-3.22] having higher likelihood of receiving any diet or exercise counseling. DISCUSSION/SIGNIFICANCE OF IMPACT: Up to 30% of Americans with diabetes received any diet or exercise counseling in ambulatory visits, and this remained low over a decade. There were significant differences in counseling across patient, provider, and practice characteristics. Future studies are needed to better understand what interventions might improve counseling in ambulatory settings.
