The successful management of diabetes with a goal of achieving near-normoglycemia requires patients to make multiple lifestyle changes as part of an intensive, complex, and coordinated therapeutic regimen aimed at reducing the risk of complications associated with the disease. The difficulty in creating and sustaining these lifestyle behavior changes is a major stumbling block in achieving the desired therapeutic goal. An underlying assumption of comprehensive disease management is that regular, personal contact with nurses and ancillary health professionals will facilitate these lifestyle behavior changes for program participants. The results of a survey of self-reported data from 750 participants in a comprehensive diabetes management program, reported on here, show strong perceptions of positive behavior change over the broad range of medical and lifestyle treatment areas associated with effective management of diabetes. These results suggest that diabetes disease management programs are an effective a...

AIMS: Intensive management of risk parameters in diabetic patients may retard the progression of both micro- and macrovascular complications. Intensified care requires expert staff and is expensive. The aim of the present study was to examine whether sharing the therapeutic responsibility with the patients will improve the outcome. METHODS: A randomized prospective study of 165 patients with diabetes mellitus Type 2, hypertension (> 140/90 mmHg) and hyperlipidaemia (LDL-C > 120 mg/dl). Patients were randomly allocated to standard annual consultation (SC) or to a patient participation programme (PP). The medical care for both groups was administered by primary care physicians, who were unaware of the nature of the intervention. RESULTS: At 4 years the mean blood pressure was 148/88 (+/- 6.1/1.7) mmHg in the SC patients vs. 142/84 (+/- 5.8/1.8) mmHg in the PP group (P = 0.02). The mean LDL-C was 124 +/- 8 and 114 +/- 6 mg/dl (P = 0.01) and the mean HbA1c was 8.9 +/- 1.2% and 8.2 +/- 1.5% (P = 0.04) in the SC and PP groups, respectively. The average annual fall in estimated glomerular filtration rate was 3.5 ml/min per year in the SC group vs. 2.25 in the PP group (P < 0.05). Albumin/creatinine ratio > 300 mg/g developed in four SC patients vs. none of the PP patients. There was a total of 36 cardiovascular events in the SC group vs. 23 in the PP group (P = 0.04). All patients in the PP group received ACE inhibitors (or AII blockers) and statins vs. 52% and 43%, respectively, in the SC group. Glucose-lowering regimens were similar. CONCLUSIONS: Well-informed and motivated patients were more insistent to reach and maintain target values of the main risk factors of diabetic complications. The differences between the PP and SC groups were of the same order of magnitude as those between intensive and standard care groups in other studies albeit with, comparatively, a very modest cost.

OBJECTIVE: We evaluated automated telephone disease management (ATDM) with telephone nurse follow-up as a strategy for improving diabetes treatment processes and outcomes in Department of Veterans Affairs (VA) clinics. We also compared the results with those of a prior ATDM trial conducted in a county health care system. RESEARCH DESIGN AND METHODS: A total of 272 VA patients with diabetes using hypoglycemic medications were randomized. During the 1-year study period, intervention patients received biweekly ATDM health assessment and self-care education calls, and a nurse educator followed up with patients based on their ATDM assessment reports. Telephone surveys were used to measure patients' self-care, symptoms, and satisfaction with care. Outpatient service use was evaluated using electronic databases and self-reports, and glycemic control was measured by HbA1c and serum glucose testing. RESULTS: At 12 months, intervention patients reported more frequent glucose self-monitoring and foot inspections than patients receiving usual care and were more likely to be seen in podiatry and diabetes specialty clinics. Intervention patients also were more likely than control patients to have had a cholesterol test. Among patients with baseline HbA1c levels > or =8%, mean end-point values were lower among intervention patients than control patients (8.7 vs. 9.2%, respectively; P = 0.04). Among intervention and control patients with baseline values > or =9%, mean end-point values were 9.1 and 10.2%, respectively (P = 0.04). At follow-up, intervention patients reported fewer symptoms of poor glycemic control than control patients and greater satisfaction with their health care. CONCLUSIONS: This intervention improved the quality of VA diabetes care. Intervention effects for most end points replicated findings from the prior county clinic trial, although intervention-control differences in the current study were smaller because of the relatively good self-care and health status among the current study's enrollees.

OBJECTIVE: To evaluate the effectiveness of a nurse-managed smoking cessation intervention in diabetic patients. RESEARCH DESIGN AND METHODS: This randomized controlled clinical trial involved 280 diabetic smokers (age range 17-84 years) who were randomized either into control (n = 133) or intervention (n = 147) groups at 12 primary care centers and 2 hospitals located in Navarre, Spain. The intervention consisted of a 40-min nurse visit that included counseling, education, and contracting information (a negotiated cessation date). The follow-up consisted of telephone calls, letters, and visits. The control group received the usual care for diabetic smokers. Baseline and 6-month follow-up measurements included smoking status (self-reported cessation was verified by urine cotinine concentrations), mean number of cigarettes smoked per day, and stage of change. RESULTS: At the 6-month follow-up, the smoking cessation incidence was 17.0% in the intervention group compared with 2.3% in the usual care group, which was a 14.7% difference (95% CI 8.2-21.3%). Among participants who continued smoking, a significant reduction was evident in the average cigarette consumption at the 6-month follow-up. The mean number of cigarettes per day decreased from 20.0 at baseline to 15.5 at 6 months for the experimental group versus from 19.7 to 18.1 for the control group (P < 0.01). CONCLUSIONS: A structured intervention managed by a single nurse was shown to be effective in changing the smoking behavior of diabetic patients.

OBJECTIVE: To assess the impact of calendar blister pack (CBP) use on glycemic and blood pressure control. RESEARCH DESIGN AND METHODS: We conducted an 8-month randomized controlled double-blind study among diabetic patients with poor glucose control (HbA1c >9.0%) in an urban area of South Auckland, New Zealand, with a high proportion of Maori and Pacific Islands people. Subjects included 68 consecutive patients, of whom 50% were prescribed three or more medications per day RESULTS: HbA1c was reduced by 0.95+/-0.22% in the CBP group and 0.15+/-0.25% in the control group (P = 0.026). Diastolic blood pressure decreased 5.8+/-1.5 mm Hg in the CBP group and increased 0.1+/-1.9 mm Hg in the control group (P = 0.0041). Systolic blood pressure did not change significantly CONCLUSIONS: CBPs should be considered among diabetic patients with poor glycemic control receiving multiple medications.

Effective control of diabetes is known to delay or prevent the end-organ complications of this disease. Can telemedicine improve a patient's ability to self-manage diabetes? Twenty-eight patients entered a study comparing home telemedicine consultation with standard outpatient care. A nurse case manager contacted the telemedicine group once a week under the direction of a primary care physician, who contacted the telemedicine group once a month. Laboratory studies and total body weight were measured at the beginning and at the end of the 3-month study. The hemoglobin A1c (HbA1c) and total body weight improved significantly in the intervention (telemedicine) group, as shown by a 16% reduction in mean HbA1c level (from 9.5 to 8.2%) and a 4% mean weight reduction (from 214.3 to 206.7 pounds). Based on our experience, we present a functionally based telemedicine classification system to improve the application of electronic medicine in future studies.

Diabetes care, morbidity, and mortality are usually worse in poor minority populations compared with non-minority ones. This report evaluates evidence-based process and outcome measures of diabetes care in diabetic patients followed in a free medical clinic and compares them to published results. The following process measures compared favorably with measures of the general population: dilated eye and foot exams and measurements of glycated hemoglobin levels; concentrations of total cholesterol; fasting triglycerides and low density lipoprotein (LDL) cholesterol; and proteinuria (by dipstick). Process and outcome measures in 89 diabetic patients referred to a Diabetes Management Program in which diabetes care was delivered by pharmacists following detailed algorithms (experimental group) were compared with measures in 92 diabetic patients who received diabetes care in the general clinic setting (control group). The patients in the experimental group had a slightly longer duration of diabetes and more microvascular and neuropathic complications, and more diabetic patients were taking insulin than were patients in the control group. All of the process measures listed above were more frequent in the experimental group. Compared with the control group, the initial glycated hemoglobin level (% +/- SE) in the experimental group was significantly (P < .001) higher (8.8 +/- 0.2 versus 7.9 +/- 0.2) but fell significantly (P < .03) more (-0.8 +/- 0.2 versus -0.05 +/- 0.3). The lack of a greater decrease in the glycated hemoglobin levels in the experimental group was not related to the inability of the pharmacists to follow the algorithms, the patients' refusal to follow the recommended medication adjustments, or the lack of appropriate self-monitoring of blood glucose in insulin-requiring patients. It was inversely related (r = -0.36, P < .03) to the number of missed visits, i.e., the greater the number of broken appointments, the less the glycated hemoglobin fell. In conclusion, diabetes care for a poor minority population in a free clinic setting can compare favorably to care in the general population. Pharmacists following detailed algorithms can enhance this care further. Administrative and support system changes that minimize the number of missed visits might further improve diabetes care in this population.

After diabetes education, 39 adult diabetic patients were randomized to either an education group or control group. The two groups received identical medical care and follow-up, except that the education group met with their diabetes educator on at least a quarterly basis. Neither group showed any statistically significant change in their glycosylated hemoglobin values, although the education group did have a 4% drop after initial education compared to a 6% rise in the control group. The education group had a lower attrition rate and a better improvement in self-rated dietary compliance. Education remains the cornerstone of diabetes management. Our team identified some trends between the two groups as well as some ideas to improve motivating and developing a stronger and more effective relationship with our patients.

A multi-center prospective study was conducted to assess the function and impact of diabetic education programs on diabetic control. A total of 208 subjects with type 2 diabetes were recruited. Diabetes self-care, assessed by questionnaire, was evaluated before, and 4 months after attending a diabetes education course. A total of 121 subjects who received advanced diabetes education courses were designated as the experimental group. A second group of 87 cases receiving a basic course served as controls. In addition to basic knowledge, the advanced education programs included dietary control, blood glucose monitoring, management of hypoglycemia, medication compliance, foot care and exercise. Diabetes self-care techniques were significantly improved in the experimental group. The overall score for diabetes self-care techniques improved in both groups at the 4th month over baseline values. The change was significant with the controls' (P < 0.001). Multiple regression analysis confirmed the intensity of diabetic education was the only significant variable correlated with the decrease of fasting blood glucose and systolic blood pressure. In conclusion, integrated and intensive diabetes education program in diabetes education centers provides an effective method for improving diabetes self-care techniques and metabolic outcome.

OBJECTIVE: To determine the impact of clinical pharmacists involved in direct patient care on the glycemic control of patients with type 2 diabetes mellitus. DESIGN: Eligible patients included those with type 2 diabetes who received insulin or were initiated on insulin therapy by the pharmacists and were willing to perform self-monitoring of blood glucose. The pharmacists provided diabetes education, medication counseling, monitoring, and insulin initiation and/or adjustments. All initial patient interactions with the pharmacists were face-to-face. Thereafter, patient-pharmacist interactions were either face-to-face or telephone contacts. SETTING: Two primary care clinics in a university-affiliated Veterans Affairs Medical Center. PARTICIPANTS: Study subjects were patients with type 2 diabetes who were referred to the pharmacists by their primary care providers for better glycemic control. OUTCOME MEASURES: Primary outcome variables were changes from baseline in glycosylated hemoglobin, fasting blood glucose, and random blood glucose measurements. Secondary outcomes were the number and severity of symptomatic episodes of hypoglycemia, and the number of emergency room visits or hospitalizations related to diabetes. Twenty-three veterans aged 65-9.4 years completed the study. Fifteen (65%) patients were initiated on insulin by the pharmacists; 8 (35%) were already using insulin. Patients were followed for a mean-SD of 27-10 weeks. Glycosylated hemoglobin, fasting blood glucose concentrations, and random blood glucose concentrations significantly decreased from baseline by 2.2% (p = 0.00004), 65 mg/dL (p < 0.01), and 82 mg/dL (p = 0.00001), respectively. Symptomatic hypoglycemic episodes occurred in 35% of patients. None of these episodes required physician intervention. CONCLUSIONS: This study demonstrates that pharmacists working as members of interdisciplinary primary care teams can positively impact glycemic control in patients with type 2 diabetes requiring insulin.
