The Impact of Primary Care Practitioner Intervention as an Adjunct to a Diabetes Case Management System.

Objective The objective of this study was to assess whether additional primary care practitioner (PCP) contacts beyond the intake visit are associated with reduced hemoglobin A1c in patients with type 2 diabetes actively engaged in the Kaiser Permanente case management system. Methods This retrospective cohort study using the Kaiser Permanente electronic health record explored the effect of enhanced PCP contact among adult patients with type 2 diabetes actively working with diabetes case managers (defined as ≥ 4 case manager contacts during the study period). Results A total of 837 patients met the inclusion and exclusion criteria. On average, patients with the highest PCP contact, < 7 contacts, had Ac levels 0.53 lower than those in the lowest PCP contact quartile, < 3 contacts (p = 0.0007). A1c decreased an average of 0.20 when the PCP contact quartile was one quartile higher (p = 0.0004). Holding the baseline A1c constant, the A1c decreased an average of 0.15 when the PCP contact quartile was one quartile higher (p = 0.0024). A1c change was significantly correlated with baseline A1c; A1c decreased by 0.64 more as the baseline A1c level increased by 1 (p < 0.0001). Additionally, the A1c level decreased by 0.02 more when patient age increased by 1 (p < 0.0001). Metformin use was associated with a decrease of A1c by 0.40 (p = 0.0057), whereas insulin use was associated with an increase of A1c by 0.29 (p = 0.0280). Conclusion In summary, a significant reduction was observed in A1c in patients with increased PCP contacts. This effect was seen in patients already receiving recommended case manager support.

Effect of Bisphosphonates on Fracture Incidence in Young Adults With Low Bone Density.

OBJECTIVE: To assess the effect of bisphosphonates on fracture incidence in young adults over a 5-year follow-up period. METHODS: Based on the Kaiser Permanente electronic health record, this retrospective study investigated patients aged 19 to 40 years with abnormal bone density (either any Z-score of ≤-2 standard deviation [SD] or any T-score of ≤-2.5 SD). The incidence and time to fracture between the control (patients with <6 months of bisphosphonate exposure) and treatment (patients with ≥6 months of bisphosphonate use within 4 years of their first dual energy x-ray absorptiometry scan) groups were compared. Comparisons were analyzed with Χ2 test for categorical variables and Wilcoxon rank sum test for continuous variables. RESULTS: A total of 422 patients met the inclusion and exclusion criteria. Fractures occurred in 18 patients (5.0%) of the control group (n = 358) and 5 patients (7.8%) of the treatment group (n = 64; P = .37). T-scores were significantly lower in the treatment group (-2.53 ± 0.58 SD) than those in the control group (-2.30 ± 0.80 SD; P = .002) but did not correlate with fracture risk. No significant differences were found in total fracture incidence (hazard ratio = 1.54; 95% confidence interval, 0.26-6.26). Similarly, no correlation was noted between the length of bisphosphonate therapy and fracture incidence (odds ratio = 0.99; 95% confidence interval, 0.966-1.026). CONCLUSION: In summary, we did not find a clear correlation of fracture incidence with the use of bisphosphonates in young adults. Further research into the pathophysiology, specific etiologies, and treatment options in this population is needed.
