N2  - Background Integrated health care models create opportunities for registered dietitian nutritionists (RDNs) to provide nutrition-related care and engage in multidisciplinary teams to improve clinical outcomes. While benefits of integrated care (IC) have been reported, little is known about the impact of the RDN within an IC model.  Objective Our primary objective was to identify whether IC vs traditional care (TC) increases the number of RDN patient visits. Our secondary objective was to evaluate clinical outcomes of patients seeing an RDN vs not, regardless of care model.  Design This was a retrospective cohort study.  Participants/setting Patients were aged 3 to 94 years and from a patient-centered medical home in Boston, MA.  Main outcome measures We measured 3-month total and average number of patients seen by the RDN in TC vs IC. Changes in adult hemoglobin A1c, weight, and pediatric body mass index (measured as kg/m2) among high-risk patients seen by an RDN compared to patients not seen by an RDN.  Statistical analysis Data were obtained from electronic medical records and analyzed utilizing Mann-Whitney U test, analysis of covariance, and paired sample t tests.  Results The RDN saw 145 patients (137 adult, 8 pediatric) in the TC model compared to 185 patients (135 adult, 50 pediatric) in the IC model. Mean number of patients seen per session was 3.20 in the TC model vs 4.63 in the IC model (P=0.004). Adult hemoglobin A1c within-group differences decreased by 0.42%±1.49% (P=0.007) for patients seen by an RDN and decreased 0.15%±1.47% (P=0.012) for patients not seen by an RDN. Adult weight within-group differences decreased 1.0±7.2 kg (P=0.15) for patients seen by a RDN and increased 0.1±5.6 kg (P=0.70) for patients not seen by a RDN. Pediatric BMI showed no change between or within groups.  Conclusions The IC model increased 3-month total number of patients seen by an RDN. High-risk patients who saw an RDN had a significant decrease in hemoglobin A1c
