Glycemic control with insulin glargine as part of an ethnically diverse, community-based diabetes management program

OBJECTIVE: To evaluate the contribution of long-acting basal insulin therapy (insulin glargine) to glycemic control in a predominantly Hispanic population participating in a community-based diabetes management program, Project Dulce. RESEARCH DESIGN AND METHODS: This retrospective analysis included 3122 adult patients with diabetes from 17 community clinics in San Diego County, California who participated in Project Dulce between July 2000 and March 2003. A subset of 180 patients received insulin glargine because of ongoing, inadequate glycemic control (ie, elevated HbA1c). Glycemic control was evaluated by mean adjusted HbA1c during follow-up clinical visits using hierarchical linear modeling, with values determined separately before and after initiation of insulin glargine. RESULTS: At baseline, the mean number of individuals with hypoglycemia, presence of diabetic complications, and duration of diabetes were greater in the glargine group that in the reference group. HbA1c at baseline was 8.79 and 9.44 (P = 0.019) in the reference and glargine groups, respectively. Mean adjusted HbA1c in the glargine group was 8.80 at baseline, 7.89 before initiation of insulin glargine (P < 0.001 vs baseline), and 7.34 after adding insulin glargine (P < 0.001 vs pre-glargine). In the reference group, mean adjusted HbA1c decreased from 8.81 at baseline to 7.40 during follow-up (P < 0.001 vs baseline). CONCLUSIONS: A comprehensive program of diabetes care in Project Dulce improved HbA1c significantly in a predominantly Hispanic population. Adding long-acting basal insulin therapy with insulin glargine produced significant incremental improvement in HbA1c.     

Translating the chronic care model into the community: results from a randomized controlled trial of a multifaceted diabetes care intervention

OBJECTIVE: To determine whether using the chronic care model (CCM) in an underserved community leads to improved clinical and behavioral outcomes for people with diabetes. RESEARCH DESIGN AND METHODS: This multilevel, cluster-design, randomized controlled trial examined the effectiveness of a CCM-based intervention in an underserved urban community. Eleven primary care practices, along with their patients, were randomized to three groups: CCM intervention (n = 30 patients), provider education only (PROV group) (n = 38), and usual care (UC group) (n = 51). RESULTS: A marked decline in HbA(1c) was observed in the CCM group (-0.6%, P = 0.008) but not in the other groups. The magnitude of the association remained strong after adjustment for clustering (P = 0.01). The same pattern was observed for a decline in non-HDL cholesterol and for the proportion of participants who self-monitor blood glucose in the CCM group (non-HDL cholesterol: -10.4 mg/dl, P = 0.24; self-monitor blood glucose: +22.2%, P < 0.0001), with statistically significant between-group differences in improvement (non-HDL cholesterol: P = 0.05; self-monitor blood glucose: P = 0.03) after adjustment. The CCM group also showed improvement in HDL cholesterol (+5.5 mg/dl, P = 0.0004), diabetes knowledge test scores (+6.7%, P = 0.07), and empowerment scores (+2, P = 0.02). CONCLUSIONS: These results suggest that implementing the CCM in the community is effective in improving clinical and behavioral outcomes in patients with diabetes.     

Diabetes management in a health maintenance organization. Efficacy of care management using cluster visits

OBJECTIVE: To evaluate the effectiveness of a cluster visit model led by a diabetes nurse educator for delivering outpatient care management to adult patients with poorly controlled diabetes. RESEARCH DESIGN AND METHODS: This study involved a randomized controlled trial among patients of Kaiser Permanente's Pleasanton, CA, center who were aged 16-75 years and had either poor glycemic control (HbA1c > 8.5%) or no HbA1c test performed during the previous year. Intervention subjects received multidisciplinary outpatient diabetes care management delivered by a diabetes nurse educator, a psychologist, a nutritionist, and a pharmacist in cluster visit settings of 10-18 patients/month for 6 months. Outcomes included change (from baseline) in HbA1c levels; self-reported changes in self-care practices, self-efficacy, and satisfaction; and utilization of inpatient and outpatient health care. RESULTS: After the intervention, HbA1c levels declined by 1.3% in the intervention subjects versus 0.2% in the control subjects (P < 0.0001). Several self-care practices and several measures of self-efficacy improved significantly in the intervention group. Satisfaction with the program was high. Both hospital (P = 0.04) and outpatient (P < 0.01) utilization were significantly lower for intervention subjects after the program. CONCLUSIONS: A 6-month cluster visit group model of care for adults with diabetes improved glycemic control, self-efficacy, and patient satisfaction and resulted in a reduction in health care utilization after the program.     

Outcomes of Project Dulce: a culturally specific diabetes management program

BACKGROUND: Diabetes mellitus is a common and costly chronic disease that increasingly affects minority populations; however, there is little evidence regarding the clinical effectiveness and costs of culturally appropriate disease management programs. OBJECTIVE: To determine the clinical outcomes and costs of Project Dulce, a combined stepped-care diabetes nurse case management program and culturally oriented peer-led self-empowerment training program. METHODS: Pre-post clinical outcome and cost analysis of Project Dulce participants were compared with a cohort of historical controls over a one-year period. Subjects included 348 persons with diabetes with coverage under County Medical Services who were receiving services in community health centers in San Diego, CA. Generalized regression models were used to estimate changes in clinical outcomes (hemoglobin [Hb] A1c, blood pressure, cholesterol level) and costs associated with participation in Project Dulce. RESULTS: Project Dulce participants had significant reductions in HbA1c (0.8%; p < 0.001), systolic (5.4 mm Hg; p = 0.001) and diastolic (8.0 mm Hg; p < 0.001) blood pressure, total cholesterol (28.1 mg/dL; p < 0.001), and low-density-lipoprotein cholesterol (15.6 mg/dL; p < 0.001). Expenditures for pharmacy ($3157 Dulce vs $1618 control) and disease management ($507 Dulce) increased. Total costs were higher during the first year of disease management ($5711 Dulce vs $4365 control; p < 0.001). CONCLUSIONS: Project Dulce was effective in improving clinical outcomes for control of diabetes and related conditions in a medically indigent, culturally diverse population. Our finding of reduced hospital expenditures, although statistically insignificant, is clinically and economically important and suggests that intervention might provide an immediate benefit to a high-risk population.     

Chronic care clinics for diabetes in primary care: a system-wide randomized trial

OBJECTIVE: To evaluate the impact of primary care group visits (chronic care clinics) on the process and outcome of care for diabetic patients. RESEARCH DESIGN AND METHODS: We evaluated the intervention in primary care practices randomized to intervention and control groups in a large-staff model health maintenance organization (HMO). Patients included diabetic patients > or = 30 years of age in each participating primary care practice, selected at random from an automated diabetes registry. Primary care practices were randomized within clinics to either a chronic care clinic (intervention) group or a usual care (control) group. The intervention group conducted periodic one-half day chronic care clinics for groups of approximately 8 diabetic patients in their respective doctor's practice. Chronic care clinics consisted of standardized assessments; visits with the primary care physician, nurse, and clinical pharmacist; and a group education/peer support meeting. We collected self-report questionnaires from patients and data from administrative systems. The questionnaires were mailed, and telephoned interviews were conducted for nonrespondents, at baseline and at 12 and 24 months; we queried the process of care received, the satisfaction with care, and the health status of each patient. Serum cholesterol and HbA1c levels and health care use and cost data was collected from HMO administrative systems. RESULTS: In an intention-to-treat analysis at 24 months, the intervention group had received significantly more recommended preventive procedures and helpful patient education. Of five primary health status indicators examined, two (SF-36 general health and bed disability days) were significantly better in the intervention group. Compared with control patients, intervention patients had slightly more primary care visits, but significantly fewer specialty and emergency room visits. Among intervention participants, we found consistently positive associations between the number of chronic care clinics attended and a number of outcomes, including patient satisfaction and HbA1c levels. CONCLUSIONS: Periodic primary care sessions organized to meet the complex needs of diabetic patients imrproved the process of diabetes care and were associated with better outcomes.     

A comparison of diabetes education administered through telemedicine versus in person

OBJECTIVE: To determine whether diabetes education can be provided as effectively through telemedicine technology as through in-person encounters with diabetes nurse and nutrition educators. RESEARCH DESIGN AND METHODS: A total of 56 adults with diabetes were randomized to receive diabetes education in person (control group) or via telemedicine (telemedicine group) and were followed prospectively. The education consisted of three consultative visits with diabetes nurse and nutrition educators. The in-person and telemedicine groups were compared using measures of glycemic control (HbA(1c)) and questionnaires to assess patient satisfaction and psychosocial functioning as related to diabetes. Outcome measures were obtained at baseline, immediately after the completion of diabetes education, and 3 months after the third educational visit. RESULTS: Patient satisfaction was high in the telemedicine group. Problem Areas in Diabetes scale scores improved significantly with diabetes education (adjusted P < 0.05, before vs. immediately after education and 3 months after education), and the attainment of behavior-change goals did not differ between groups. With diabetes education, HbA(1c) improved from 8.6 +/- 1.8% at baseline to 7.8 +/- 1.5% immediately after education and 7.8 +/- 1.8% 3 months after the third educational visit (unadjusted P < 0.001, P = 0.089 adjusted for BMI and age), with similar changes observed in the telemedicine and in-person groups. CONCLUSIONS: Diabetes education via telemedicine and in person was equally effective in improving glycemic control, and both methods were well accepted by patients. Reduced diabetes-related stress was observed in both groups. These data suggest that telemedicine can be successfully used to provide diabetes education to patients.     

A 5-year randomized controlled study of learning, problem solving ability, and quality of life modifications in people with type 2 diabetes managed by group care

OBJECTIVE: To study time course changes in knowledge, problem solving ability, and quality of life in patients with type 2 diabetes managed by group compared with individual care and education. RESEARCH DESIGN AND METHODS: We conducted a 5-year randomized controlled clinical trial of continuing systemic education delivered by group versus individual diabetes care in a hospital-based secondary care diabetes unit. There were 120 patients with non-insulin-treated type 2 diabetes enrolled and randomly allocated to group or individual care. Eight did not start and 28 did not complete the study. The main outcome measures were knowledge of diabetes, problem solving ability, quality of life, HbA1c, BMI, and HDL cholesterol. RESULTS: Knowledge of diabetes and problem solving ability improved from year 1 with group care and worsened among control subjects (P<0.001 for both). Quality of life improved from year 2 with group care but worsened with individual care (P<0.001). HbA1c level progressively increased over 5 years among control subjects (+1.7%, 95% CI 1.1-2.2) but not group care patients (+0.1%, -0.5 to 0.4), in whom BMI decreased (-1.4, -2.0 to -0.7) and HDL cholesterol increased (+0.14 mmol/l, 0.07-0.22). CONCLUSIONS: Adults with type 2 diabetes can acquire specific knowledge and conscious behaviors if exposed to educational procedures and settings tailored to their needs. Traditional one-to-one care, although delivered according to optimized criteria, is associated with progressive deterioration of knowledge, problem solving ability, and quality of life. Better cognitive and psychosocial results are associated with more favorable clinical outcomes.     

Failure to maintain the benefits of home-based intervention in adolescents with poorly controlled type 1 diabetes

OBJECTIVE: To determine whether a 6-month home-based intervention program in adolescents with poorly controlled diabetes improves metabolic control and whether benefits are maintained after the intervention. RESEARCH DESIGN AND METHODS: Adolescents with a mean HbA1c of > 9.0% over the preceding 12 months received either routine care in a diabetes clinic and an ambulatory intervention for 6 months (n = 37) or routine care only (n = 32). A diabetes educator provided monthly home visits and weekly phone contact to educate and support the adolescents in setting goals for insulin adjustment, blood glucose monitoring, and target blood glucose range. There was no systematic change in the frequency of insulin injections. After the intervention, there was a 12-month follow-up when the intervention and control groups both received only routine care. Outcome measures were HbA1c and Diabetes Knowledge Assessment (DKN). RESULTS: During the intervention, mean HbA1c fell (baseline: 11.1 +/- 1.3%, 6 months: 9.7 +/- 1.6%; P = 0.0001) and mean knowledge scores increased (P = 0.0001) in the intervention group but not in control subjects. However, this improvement in HbA1c and increase in knowledge was not maintained in the intervention group at 12- and 18-month follow-up assessments. Parents' knowledge scores also improved significantly from baseline levels in the intervention group at 6 and 12 months (P = 0.001, P = 0.005, respectively). CONCLUSIONS: An ambulatory program improves metabolic control and knowledge in adolescents with poorly controlled type 1 diabetes; however, it is effective only while the intervention is maintained.     

Peer-led diabetes education programs in high-risk Mexican Americans improve glycemic control compared with standard approaches: a Project Dulce promotora randomized trial

OBJECTIVE

To evaluate the effect of a culturally sensitive diabetes self-management education program that uses a low-cost, peer-educator format (Project Dulce) on glucose control and metabolic parameters in low-income Mexican Americans with type 2 diabetes.

RESEARCH DESIGN AND METHODS

A total of 207 Mexican-American patients recruited from federally funded community health centers in San Diego County with HbA_1c >8% were randomly assigned to the Project Dulce peer intervention or continuation of standard diabetes care. The primary outcome of interest was HbA_1c.

RESULTS

The majority of subjects were born in Mexico, were female, were middle-aged, had less than an eighth-grade education, and had high baseline HbA_1c levels. Significant time-by-group interaction effects for HbA_1c (P = 0.02) and diastolic blood pressure (P = 0.04) indicated that the Project Dulce group exhibited greater improvement (i.e., decreases) across time. Within-group analyses showed that the intervention group exhibited significant improvements from baseline to month 4 in absolute levels of HbA_1c (−1.7%, P = 0.001) and HDL cholesterol (+1.4 mg/dL, P = 0.01) and from baseline to month 10 in absolute levels of HbA_1c (−1.5%, P = 0.01), total cholesterol (−7.2 mg/dL, P = 0.04), HDL cholesterol (+1.6 mg/dL, P = 0.01), and LDL cholesterol (−8.1 mg/dL, P = 0.02). No significant changes were noted in the control group.

CONCLUSIONS

This randomized trial, using the Project Dulce model of culturally sensitive, peer-led education, demonstrates improvement in glucose and metabolic control and suggests that this low-cost approach to self-management education for high-risk diabetic populations is effective.Health care reform is a driving force with the imperative to identify low-cost and clinically effective methods to respond to the increasing health care needs of our society. In addition, targeting effective interventions toward those with significantly elevated clinical risk factors may help to foster cost containment. By 2034, the number of patients with diagnosed and undiagnosed diabetes is predicted to increase from 23.7 to 44.1 million, and annual diabetes-related spending is expected to increase from $113 to $336 billion (1). Patients of Latino origin are a vulnerable population whose health care needs, particularly in diabetes care, are rising exponentially. Predictions are that between 45 and 55% of Hispanics born in the year 2000 will develop diabetes during their lifetime (2). Along with this disease burden, additional cultural barriers exist, preventing optimal care and clinical benefit in these groups, putting them at even greater risk for high-cost complications. Culturally appropriate, clinically sound, and cost-effective models are needed to respond to the growing and diverse populations affected by diabetes worldwide.Improved glucose control can positively impact the health status of patients with diabetes and reduce comorbidities associated with their treatment (3–5). Latinos with type 2 diabetes in particular exhibit worse glycemic control, have greater disease severity, develop a higher rate of complications, and overall have worse health outcomes than non-Latino whites with the same condition (6–8). The peer-educator model, particularly in relation to diabetes, may be useful as a method that improves glucose control (9–13). The Project Dulce model was developed in 1997 to improve the health of underserved, ethnically diverse people with diabetes (14,15). As originally designed, this model consisted of three components: nurse case management, dietitian visits, and a series of peer-led, self-management education classes. Reports published to date on the outcomes of the Project Dulce model included all three of these components (14–16). The present trial, however, was designed to directly evaluate the effect of the peer-led education classes alone as one factor in the chronic-care model that can lead to improved clinical outcomes. Although the peer-education program has been tested in qualitative and quantitative studies over the last 10 years, it has never been rigorously tested in a randomized trial. The Project Dulce peer-education component, developed by the Scripps Whittier Diabetes Institute, uses lay community health workers, or promotoras, who act as cultural mediators among patients, community resources, and the greater health care system (16). The purpose of this study was to assess whether this culturally sensitive diabetes self-management education program can improve glucose control and metabolic parameters in Mexican Americans.     

The association of diabetes specialist care with health care practices and glycemic control in patients with type 1 diabetes: a cross-sectional analysis from the Pittsburgh epidemiology of diabetes complications study

OBJECTIVE: To determine whether diabetes care characteristics and glycemic control differ by use of specialist care in a representative cohort of patients with type 1 diabetes. RESEARCH DESIGN AND METHODS: Health care, sociodemographic characteristics, and glycemic control were compared between participants in the Pittsburgh Epidemiology of Diabetes Complications Study who reported receiving specialist care (n = 212) and those who did not (n = 217). Specialist care was defined as having received care from an endocrinologist or diabetologist or diabetes clinic attendance during the last year. RESULTS: Patients who reported receiving specialist care were more likely to be female, to have an education level beyond high school, to have an annual household income >$20,000, and to have health insurance. Additionally, patients receiving specialist care were more likely to have received diabetes education during the previous 3 years, to have knowledge of HbAlc testing and to have received that test during the previous 6 months, to have knowledge of the Diabetes Control and Complications Trial results, to self-monitor blood glucose, and to inject insulin more than twice daily. A lower HbA1 level was associated with specialist care versus generalist care (9.7 vs. 10.3%; P = 0.0006) as were higher education and income levels. Multivariate analyses suggest that the lower HbA1 levels observed in patients receiving specialist care were restricted to patients with an annual income >$20,000. CONCLUSIONS: Specialist care was associated with higher levels of participation in diabetes self-care practices and a lower HbA1 level. Future efforts should research and address the failure of patients with low incomes to benefit from specialist care.     

Managed care organization and the quality of diabetes care: the Translating Research Into Action for Diabetes (TRIAD) study

OBJECTIVE: To examine the association between the organizational model and diabetes processes of care. RESEARCH DESIGN AND METHODS: We used data from the Translating Research into Action for Diabetes (TRIAD), a multicenter study of diabetes care in managed care, including 8354 patients with diabetes. We identified five model types: for-profit group/network, for-profit independent practice association (IPA), nonprofit group/network, nonprofit IPA, and nonprofit group/staff. Process measures included retinal, renal, foot, lipid, and HbA(1c) testing; aspirin recommendations; influenza vaccination; and a sum of these seven processes of care over 1 year. Hierarchical regression models were constructed for each process measure and accounted for clustering at the health plan and provider group levels and adjusted for participant age, sex, race, ethnicity, diabetes treatment and duration, education, income, health status, and survey language. RESULTS: Participant membership in the model types ranged from 9% in nonprofit IPA models to 38% in nonprofit group/staff models. Over 75% of participants received most of the processes of care, regardless of model type. However, among for-profit plans, group/network models provided on average more processes of care than IPA models (5.5 vs. 4.7, P < 0.0001), and group/network models generally increased the probability of receiving a process by >or=10 percentage points. Among nonprofit plans, no effect of model type was found. CONCLUSIONS: Among for-profit plans, group/network models provided better diabetes processes of care than IPA models. Although reasons are speculative, this may be due to the clinical infrastructure available in group models that is not available in IPA models.     

A randomized controlled trial of the effects of nurse case manager and community health worker team interventions in urban African-Americans with type 2 diabetes

The objective of the study was to determine the effectiveness and cost-effectiveness of primary care and community-oriented interventions in managing HbA1c, blood pressure, and lipids, and reducing hospitalizations and emergency room visits over 2 years. We describe an ongoing, randomized controlled trial of 542 urban African-Americans with type 2 diabetes ages 25 years and older who are members of a university-affiliated managed-care organization in Baltimore, MD. The participants are 74% female, have a mean age of 58 years, and 35% have yearly incomes greater than 7500 US dollars. Participants were randomized to one of two intervention groups for a period of 2 years: (1) usual medical care plus minimal telephone intervention implemented by a trained lay health educator (control group) or (2) usual medical care plus intensive intervention implemented by a nurse case manager (NCM)/community health worker (CHW) team. The intensive NCM/CHW team executes individual plans of care using evidence-based algorithms that focus on traditional diabetes self-management, screening and management of diabetes-related complications, and social issues surrounding diabetes care. Face-to-face NCM visits are conducted in the clinic once per year and CHW visits are conducted in the participant's home one to three times per year, both with additional follow-up contacts as needed. Written and verbal feedback (when necessary) is provided to the participant's primary care physician. All participants are expected to attend a 24-month follow-up visit where data are collected by interviewers blinded to intervention assignment. As of May 1, 2003, recruitment is complete, interventions are being fully implemented, and 24-month follow-up visits are beginning. Baseline sociodemographic characteristics, health-care utilization, health behaviors, and clinical characteristics of the study population are reported. This study is designed to test the hypothesis that a primary-care-based NCM plus CHW team approach is an effective, practical, and economically feasible strategy for translating current knowledge about type 2 diabetes into high-quality health care for urban African-Americans.     

The effect of automated calls with telephone nurse follow-up on patient-centered outcomes of diabetes care: a randomized, controlled trial

OBJECTIVE: We evaluated the impact of automated telephone disease management (ATDM) calls with telephone nurse follow-up as a strategy for improving outcomes such as mental health, self-efficacy, satisfaction with care, and health-related quality of life (HRQL) among low-income patients with diabetes mellitus. RESEARCH DESIGN: This was a randomized, controlled trial. SUBJECTS: Two hundred forty-eight primarily English- and Spanish-speaking adults with diabetes enrolled at the time of visits to a county health care system. INTERVENTION: In addition to usual care, intervention patients received biweekly ATDM calls with telephone follow-up by a diabetes nurse educator. Patients used the ATDM calls to report information about their health and self-care and to access self-care education. The nurse used patients' ATDM reports to allocate her time according to their needs. MEASURES: Patient-centered outcomes were measured at 12 months via telephone interview. RESULTS: Compared with patients receiving usual care, intervention patients at follow-up reported fewer symptoms of depression (P = 0.023), greater self-efficacy to conduct self-care activities (P = 0.006), and fewer days in bed because of illness (P = 0.026). Among English-speaking patients, those receiving the intervention reported greater satisfaction with their health care overall and with the technical quality of the services they received, their choice of providers and continuity of care, their communication with providers, and the quality of their health outcomes (all P <0.042). Intervention and control patients had roughly equivalent scores for established measures of anxiety, diabetes-specific HRQL, and general HRQL. CONCLUSIONS: This intervention had several positive effects on patient-centered outcomes of care but no measurable effects on anxiety or HRQL.     

Peer Education Project with Persons who have Experienced Homelessness

This paper describes an unconventional health education project implemented by nurse practitioners in a nurse-managed clinic serving persons who are homeless. The nurse practitioners perceived that there were a number of potential barriers to providing health education to the homeless patients. These barriers included the fact that this patient population is part of a marginalized subculture affected by a variety of overwhelming social problems. An additional barrier was that the nurses often differed from their homeless patients in terms of race, gender, socioeconomic status, formal education, culture, and life experience. The nurse practitioners designed the Peer Health Education Project (PHEP) to try to overcome some of these barriers. The purpose of the PHEP was to increase the health education knowledge and empowerment of persons who had experienced homelessness so that they could serve as peer health educators with others who were living on the streets. The project model was based on the philosophy of Paulo Freire (1973). The peer health educators served as both leaders and participants in each education session. The educators set the agenda and the nurses acted as facilitators. The project was successful in preparing peer educators. Other indicators of the success of the project included increased empowerment, self-esteem, dignity, hope self-confidence, and community participation of the peer educators.     

Monitoring of psychological well-being in outpatients with diabetes: effects on mood, HbA(1c), and the patient's evaluation of the quality of diabetes care: a randomized controlled trial.

OBJECTIVE: To investigate whether monitoring and discussing psychological well-being in outpatients with diabetes improves mood, glycemic control, and the patient's evaluation of the quality of diabetes care. RESEARCH DESIGN AND METHODS: This study was a randomized controlled trial of 461 outpatients with diabetes who were randomly assigned to standard care or to the monitoring condition. In the latter group, the diabetes nurse specialist assessed and discussed psychological well-being with the patient (with an interval of 6 months) in addition to standard care. The computerized Well-being Questionnaire was used for this purpose. Primary outcomes were mood, HbA(1c), and the patient's evaluation of the quality of diabetes care at 1-year follow-up. The number of referrals to the psychologist was analyzed as a secondary outcome. Intention-to-treat analysis was used. RESULTS: The monitoring group reported better mood compared with the standard care group, as indicated by significantly lower negative well-being and significantly higher levels of energy, higher general well-being, better mental health, and a more positive evaluation of the quality of the emotional support received from the diabetes nurse. The two groups did not differ for HbA(1c) or in their overall evaluation of the quality of diabetes care. In the monitoring condition, significantly more subjects were referred to the psychologist. CONCLUSIONS: Monitoring and discussing psychological well-being as part of routine diabetes outpatient care had favorable effects on the mood of patients but did not affect their HbA(1c). Our results support the recommendation to monitor psychological well-being in patients with diabetes.     

Organizational determinants of high-quality routine diabetes care

Abstract

Objective. Randomized trials showed that changes in healthcare organization improved diabetes care. This study aimed to identify which organizational determinants were associated with patient outcomes in routine diabetes care. Design. Observational study, in which multilevel regression analyses were applied to examine the impact of 12 organizational determinants on diabetes care as separate measures and as a composite score. Setting. Primary care practices in the Netherlands. Subjects. 11,751 patients with diabetes in 354 practices. Main outcome measures. Patients’ recorded glycated hemoglobin (HbA1c), systolic blood pressure, and serum cholesterol levels. Results. A higher score on the composite measure of organizational determinants was associated with better control of systolic blood pressure (p = 0.017). No effects on HbA1C or cholesterol levels were found. Exploration of specific organizational factors found significant impact of use of an electronic patient registry on HbA1c (OR = 1.80, 95% CI 1.12–2.88), availability of patient leaflets on systolic blood pressure control (OR = 2.59, 95% CI 1.06–6.35), and number of hours’ nurse education on cholesterol control (OR = 2.51, 95% CI 1.02–6.15). Conclusion. In routine primary care, it was found that favorable healthcare organization was associated with a number of intermediate outcomes in diabetes care. This finding lends support to the findings of trials on organizational changes in diabetes care. Notably, the composite measure of organizational determinants had most impact.     

Rural diabetes education: does it make a difference?

This cross-sectional study using a mailed survey evaluated outcomes of diabetes education, care, and support provided at 2 clinics in rural Manitoba, Canada. Seventy-eight respondents with type 2 diabetes, including 51 rural clinic attenders and 27 non-attenders (mean age = 68.5), were compared regarding demographic characteristics; diabetes education and knowledge; diabetes self-management efficacy, attitudes, and behaviours; quality of life; satisfaction with care; and health-care utilization. Attenders had more diabetes education (P < .001), higher self-management efficacy scores (P < .051), and greater satisfaction with diabetes care (P < .001) than non attenders, but more education did not translate into greater diabetes-related knowledge, attitudes, or behaviours. While clinic attendance and supportive interaction with health professionals and peers may help equip people with type 2 diabetes with the confidence and alternative strategies to handle diabetes-related health problems, a more standard approach to diabetes education and care could improve the achievement of desired outcomes.     

Substitution model with central role for nurse specialist is justified in the care for stable type 2 diabetic outpatients

AIM OF THE STUDY: Assessment of effects on quality of care, in terms of patient outcomes, when tasks in the care for outpatients with stable type 2 diabetes are transferred from internist to nurse specialist and from outpatient clinic to general practice. BACKGROUND: For the management of chronic diseases with a high prevalence and requiring current monitoring, it is suggested that substitution of care may be an appropriate solution to safeguard high quality care. DESIGN AND METHODS: A 12-month nonequivalent control group design was used. General practitioners (GPs) referring diabetes patients to the University Hospital Maastricht were asked to choose for the traditional model or the nurse specialist model. Informed consent was obtained from patients with stable diabetes type 2 attending these practices. All patients received care according to the model chosen by their GP. Identified outcomes were: clinical status, health status, self-care behaviour, knowledge of diabetes, patient satisfaction, and consultation with care-providers. RESULTS: In the control group (n=47) no patients were treated with oral hypoglycaemic agents (OHA) only. The control group was compared with an intervention subgroup (n=52) also without patients receiving OHA only. Clinical data were available for all patients. Patients without complete data from questionnaires had better mean concentration of HbA1c than patients with complete data (P=0.004). The traditional care model and the nurse specialist model achieved equal outcomes, while glycaemic control of patients in the nurse specialist model improved (from 8.6% to 8.3%) but deteriorated in the traditional model (from 8.6% to 8.8%; P-value between groups=0.001). CONCLUSIONS: The model with nurse specialists taking on roles and tasks beyond those traditionally regarded as their remit as well as new ones, is effective for the care of stable diabetic outpatients.
