Pharmacist-physician collaboration for diabetes care: the diabetes initiative program.

BACKGROUND: Multiple complications can arise secondary to poor control of glucose, blood pressure, and cholesterol in a patient with diabetes. OBJECTIVE: To evaluate the effect of a pharmacist-physician collaboration on attainment of diabetes-related measures of control. METHODS: This was a prospective, multicenter, cohort study. Patients were enrolled from 7 practice sites throughout Tennessee if they had been diagnosed with type 2 diabetes, were aged 18 years or older with a life expectancy greater than 1 year, and were English speaking. Pregnant women were excluded. Patients were followed for 12 months following enrollment by informed consent. The pharmacist-physician collaboration method was established prior to study initiation. Primary outcomes included hemoglobin A1c (A1C), number of patients with A1C less than 7%, and percentage of patients with A1C greater than 9%. RESULTS: Of the 206 patients enrolled, the mean age was 59.73 years, and most were male (59.71%) and white (66.02%). The A1C was reduced by an average of 1.16% (p < 0.0001). The proportion of patients with A1C less than 7% increased from 12.75% at baseline to 36.76% at study conclusion (p = 0.0002). The proportion of patients with A1C greater than 9% decreased from 34.15% to 16.50%, (p < 0.0001). CONCLUSIONS: Pharmacist-physician collaborative management at multiple practice locations and types of setting (eg, private, academic, Veterans Affairs medical center) has a positive impact on glycemic control and diabetes-related health maintenance. This was accomplished without increasing the total number of antihyperglycemic agents prescribed and without an increase in patient-reported episodes of hypoglycemia.

Retrospective analysis and patient satisfaction assessment of insulin pump therapy in patients with type 2 diabetes.

OBJECTIVES: To evaluate and assess glycemic control, total daily insulin requirements, weight, and patient satisfaction after changing from multiple daily injections (MDI) to continuous subcutaneous insulin infusion (CSII) therapy in patients with type 2 diabetes. METHODS: This was a retrospective cross-sectional cohort analysis of an electronic medical records database from a private physician's clinic. Patients over 18 years of age who had type 2 diabetes and who utilized CSII for at least six months were analyzed. Variables of interest included glycosylated hemoglobin, total daily insulin requirements, and weight at the time of conversion from MDI to CSII. Patients were also asked to complete a satisfaction survey comparing MDI to CSII. RESULTS: Thirty patients who met the inclusion criteria were identified. Hemoglobin A1c (HbA1c) decreased from 9.25% ± 2.20 to 7.94% ± 1.65 (P < 0.001) at six months, total daily insulin dose decreased from 1.33 ± 0.66 u/kg/day to 1.08 ± 0.70 u/kg/day (P < 0.001) at six months, and weight increased from 106.66 ± 19.17 kg to 109.75 ± 18.01 kg (P < 0.001). After twelve months, HbA1c did not significantly change and weight returned to baseline; however, total daily insulin dose significantly decreased. 95% of patients preferred CSII therapy to previous injection regimen for various reasons. CONCLUSION: Insulin pump therapy provided better glycemic control and reduced the total amount of insulin utilized. Patients who utilized CSII thought that the treatment was more convenient, less burdensome, and provided better control of fluctuations in blood glucose. CSII was preferred by patients over multiple daily injections.

Falsely low hemoglobin A1c levels in a patient receiving ribavirin and peginterferon alfa-2b for hepatitis C.

The effect of treatment for hepatitis C viral infection on hemoglobin A(1c) (A1C) levels is not well described in the literature. We describe a 59-year-old man with type 2 diabetes mellitus whose A1C level became falsely low when ribavirin and peginterferon alfa-2b therapy were started for treatment of hepatitis C. After treatment was discontinued, the patient's A1C returned to its previous baseline value. Use of the Naranjo adverse drug reaction probability scale indicated a probable relationship (score of 7) between the patient's low AIC level and his ribavirin-peginterferon alfa-2b therapy. Clinicians should be aware that combination therapy for hepatitis C may affect A1C values. To maintain accurate glucose control in patients with diabetes who are receiving treatment for hepatitis C, it is important that they self-monitor their blood glucose levels in conjunction with A1C data, especially when A1C values become falsely low.
