© American Diabetes Association ®, Inc., 2006 Group Education Strategies for Diabetes Self-Management
In Brief Empowerment-based diabetes group education emphasizes strategies that are patient centered, problem based, culturally relevant, integrative, and evidence based. These programs and strategies can be conducted across a variety of educational and clinical settings with the goal of responding to the unique diabetes-related needs of each patient.
Diabetes self-management education (DSME) is recognized as a fundamental component of diabetes care.1 The goal of DSME is to help patients acquire the knowledge, information, self-care practices, coping skills, and attitudes required for the effective self-management of their diabetes. Several reviews and meta-analyses have found DSME interventions to have a positive impact on diabetes-related health and psychosocial outcomes, specifically increasing diabetes-related knowledge and improving blood glucose monitoring, dietary and exercise habits, foot care, medication taking, coping, and glycemic control.26 Although group-based approaches have been associated with several advantages (e.g., cost-effectiveness, patient satisfaction, and interactive learning),1,79 to date, the literature has only begun to investigate and describe different approaches to group-based DSME. Although the evidence supports the efficacy of DSME programs as a whole, variability in program goals, outcome measures, length of intervention, frequency of sessions, learning format, and demographic background of participants has meant that there is no known prototype for the optimal DSME program.10 The three objectives of this article are to:
Although a large body of evidence supports the efficacy of DSME interventions in improving diabetes-related health outcomes, few studies to date have investigated the impact of the DSME delivery format on diabetes health-related outcomes. According to Mensing and Norris1 a group is "a gathering or an assembly of persons with a common interest." The Centers for Medicare and Medicaid Services (CMS) has recommended a group size for patient education of 220 members, with an average of 10 participants.11 Compared to individual-based approaches, group-based approaches typically invite greater interaction and interpersonal dynamics.1 Moreover, the group setting can foster certain educational activities, such as social modeling or problem-based learning better than the individual setting. Some providers believe group-based DSME is better than individual-based DSME at improving diabetes-related health outcomes.7 Group education is also thought to be less costly than individual education.7,8 In fact, the Balanced Budget Act of 1997 provided a further economic incentive for group-based programs because it specifically recognized diabetes education via a group format for uniform reimbursement by the CMS. In a qualitative review, Norris et al.2 examined individual versus group approaches to DSME. These authors found that patients in both settings demonstrated equal success in acquiring and honing self-care practices. The only self-management practices in which group-based learning led to slightly better self-care outcomes than individual-based learning was nutritional management and physical activity. They concluded that each intervention approach offered unique features and benefits. In a later review article, Norris et al.3 found no differential impact between individual versus group-based interventions for improving glycemic control. Another review conducted by Deakin et al.12 found that among patients diagnosed with type 2 diabetes, group-based education was effective for improving fasting blood glucose levels, hemoglobin A1c (A1C), systolic blood pressure, body weight, need for medication, and diabetes knowledge. A small number of studies have specifically compared individual versus group formats for DSME. Among a sample of patients diagnosed with type 2 diabetes, Erskine et al.9 investigated differences in patient satisfaction and glycemic control between participants receiving individual insulin education versus group-based education. Although no group differences were revealed for glycemic control at the 1-year follow-up, these authors did find patients in the group condition reported significantly higher rates of satisfaction with their diabetes treatment than their individual education counterparts. Campbell et al.13 conducted a randomized trial comparing four conditions: a basic 2-session program, an individual 12-session program, a 3-day group education program, and an individualized behavioral program. Participation in any of the four programs was associated with improvements in A1C and BMI, with no significant differences between the conditions. In a randomized controlled study, Rickheim et al.7 examined the efficacy of DSME delivered in individual versus group-based settings among 170 patients with type 2 diabetes. Both group and individual interventions consisted of four sessions at baseline, 2 weeks, 3 months, and 6 months. A standardized curriculum was presented to participants in both conditions. Diabetes-related knowledge, attitudes, and quality of life; psychosocial adjustment; physical activity; A1C; BMI; and weight were assessed at all time points. Patients in both group and individual conditions improved in diabetes-related knowledge, attitudes, psychosocial adjustment, and weight. Both groups also significantly decreased their A1C from start to completion of the intervention. However, the reduction in A1C was slightly greater for participants in the group intervention than for those in the individual intervention. Overall, group and individual DSME modalities were similarly effective in improving diabetes-related health outcomes, with the group approach slightly superior to the individual approach in improving glycemic control. Among the small number of studies that have compared group-based DSME with individual DSME, it would appear that there are no clear and consistent differences in diabetes-related health outcomes. However, some data support the hypothesis that group-based DSME can be more cost-effective, lead to greater treatment satisfaction, and be slightly more effective for lifestyle behavioral changes, such as diet and physical activity.
The majority of studies that have reported successful outcomes in group programs have not included a detailed description of the theoretical approach or of the intervention itself, including the specific strategies utilized.10 As a result, the literature on group DSME lacks a coherent, constantly evolving knowledge base elucidating the most effective theoretically based group programs. The following section describes three group-based interventions that have been developed and conducted based on the empowerment approach to diabetes education and behavior change. Using empowerment as the theoretical foundation, these programs have provided a series of educational strategies that, generally, differ significantly from traditional lecture-based group education. In addition, all three programs have been culturally tailored to meet the needs of African Americans living in urban settings. The first program illustrates how the empowerment approach to informal group and individual DMSE has been provided in different health care and research settings.14 The second program is a DSME intervention delivered in response to patients' diabetes-related needs, concerns, and priorities, as well as the social and cultural communities in which they live.15 The third program is a community-based intervention created to support sustained diabetes self-management for 6 months (and eventually for longer) as a follow-up to DSME.16
Capitalizing on opportunities to deliver informal DSME
The community-based screening program consisted of several diabetes-related
health components. Upon arrival to the "clinic" (clinics were held
in churches, senior centers, recreation centers, and other community
locations), participants rotated through several health screening stations
(e.g., height, weight, blood pressure, A1C, and blood glucose level). After
completing the series of health screening stations, patients received a
dilated eye exam. The dilated exam procedure followed a three-step process:
1) receiving the dilation eye drops, 2) waiting for During these screening clinics, there were numerous opportunities to provide informal diabetes education (Table 1). Each clinic had at least one diabetes educator on site. The educator conducted small group discussions and answered questions in the waiting area throughout the duration of the clinics. Patients guided the dialogue based on their specific diabetes-related concerns, questions, and priorities. In other words, the patient education was unstructured, informal, ongoing, and free flowing, with patients constantly joining, leaving, and rejoining the group.
At time of checkout, all test results were reviewed with the patients, who were then invited to ask questions about their results. In addition to this debriefing, patients were given a written copy of their results and another was mailed to them within several weeks. Written results included blood pressure, eye exam results, and A1C and a description of both normal and abnormal results. The test results were also sent to participant-identified primary care providers. Gillard et al.14 investigated the impact of these informal learning experiences on glycemic control and self-care behaviors. Medication use, self-monitoring of blood glucose (SMBG), and A1C were measured at baseline and at second- and third-annual screenings. Significant (P = 0.03) improvements in A1C were seen between the baseline (9.2%) and the second (8.9%) and third screenings (8.6%). The percentage of patients practicing SMBG significantly (P < 0.01) increased from 61% at baseline to 71% at the second screening and 76% at the third screening. Finally, the percentage of patients on insulin therapy increased from 37 to 42% across the successive screening points. However, the increase in the percentage of patients using insulin did not explain the improvements in A1C because patients who did not start on insulin during the study improved as much as those who did start insulin. Although the primary purpose of this clinic was to provide free retinopathy screening for African Americans living in Detroit, this intervention also resulted in secondary gains by providing opportunities for informal diabetes education within the program. Table 1 describes the multiple informal learning opportunities within this clinic program, including having access to educational materials at the clinic, undergoing the process of informed consent, discussing eye screening results with the ophthalmologist, interacting with clinic staff, participating in "ask the expert" waiting room sessions, and receiving health care station results. The retinopathy clinic was not purposely designed as a DSME program, but it did foster the learning process across multiple educational opportunities. Although not currently reimbursable, this type of model may be useful for office-based practices where annual or routine visits for patients with diabetes are scheduled for a particular day so that waiting time can be efficiently used as an educational opportunity.
Conducting a culturally tailored, problem-based, community group education program This program was designed to support patients in achieving their goals by responding to the unique self-management problems and issues they raised (i.e., problem based). Groups were co-facilitated by a nurse and a dietitian who were also certified diabetes educators. Table 2 presents the five core components that were part of each session. The five components included reflecting on relevant experiences, discussing the role of emotion, engaging in systematic problem solving, answering clinical questions, and providing feedback. The problem solving process followed the five-step empowerment model presented in Table 2.20
At the first session, facilitators presented the philosophy of the program, established ground rules, reminded patients that they were the experts of their own diabetes, and gave patients their personal diabetes-related health status report including their A1C, lipid, blood pressure, and weight results. This report also included the normal ranges for these values. Facilitators then invited patients to ask any questions triggered by this report as well as any other questions or concerns they wanted to raise. Therefore, the content and flow of discussion was guided entirely by their questions, priorities, and concerns. Before the end of the session, facilitators explained the five-step empowerment model and encouraged but did not require patients to identify a short-term behavioral goal they would work on during the following week. The following five sessions usually began with a discussion about this experience. Although there were no formalized lectures and curriculum, the self-management topics identified by the National Standards for Diabetes Self-Management Education21 were addressed during the course of the six sessions. In addition, psychosocial, behavioral, and cultural issues were integrated throughout the program as participants raised these issues. Patients received a resource handbook based on the type 2 diabetes curriculum and tailored for African Americans.22 The DSME program included a built-in follow-up component through which patients could choose to participate in monthly support groups similar to the 6-week group sessions or receive a monthly phone call from the nurse. During the calls, the nurse encouraged patients to discuss their self-management plans, progress toward goals, challenges, and emotional concerns. The nurse also invited patients to refine self-management techniques or make action plans based on these discussions. An evaluation of the program found that patients, as a group, made modest improvements in A1C, cholesterol, weight, perceived understanding of diabetes, personal sense of empowerment, and diabetes-related attitudes and that these improvements were sustained for at least 1 year. Patients in the two follow-up interventions sustained or improved their A1C values with a higher number of follow-up contacts positively associated with better A1C values. This model is most well suited for a hospital or community-based group DSME program where meeting DSME national standards21 is important for reimbursement.
Supporting diabetes self-management over the lifetime LM is an extension of the previously described problem-based DSME program. It is a community-based, patient-centered, long-term self-management intervention that was found to be feasible for and culturally acceptable to African-American adults with type 2 diabetes living in the greater Detroit area.16 The goal of the LM intervention was to help patients sustain and improve diabetes self-management gains they have achieved through previous short-term DSME programs. Therefore, patients were required to have at least received a basic level of diabetes education either from a patient education course or from individual education with diabetes-specialty health care professionals (e.g., dietitian, nurse, physician, or other diabetes educators) within the past 3 years. The LM pilot program consisted of 24 weekly sessions (90 minutes in length) held over a period of 6 months. The direction and flow of each session were guided by patient-identified interests, concerns, and experiences. Patients were encouraged to attend sessions as frequently as needed. Based on individual self-perceived support needs, attendance could be weekly, monthly, or sporadic depending on the experiences and events in patients' lives. A two-person team consisting of a certified diabetes educator and a clinical psychologist facilitated these groups. Similar to the empowerment group program of Anderson et al.,15 LM sessions were structured with the five components, including reflecting on relevant experiences, discussing the role of emotion, engaging in systematic problem solving, answering clinical questions, and providing feedback (Table 2).15 Patients raised issues and challenges they faced, and the group leader facilitated a process of problem solving with other group members, using the empowerment model presented in Table 3. Major self-management areas were outlined on a poster board to help trigger group discussion about diabetes-related experiences. Sessions were conducted at different times of the day and at different locations throughout the community to accommodate varying schedules.
All educational materials were compiled in a resource binder called the Lifelong Management Guidebook, which patients received at the outset of the program. Patients were encouraged to bring the binder to each session and to use it as a reference at home. The guidebook was organized into seven sections reflecting the major components of diabetes self-management education.21 These included eating and diet, taking medications, exercise, monitoring glucose, problem solving for glucose management, reducing risks of complications, and living with diabetes. Participation in the LM intervention was found to be associated with significant improvements in diabetes-related health outcomes.16 After the LM program, patients demonstrated significant improvements in BMI and serum total, HDL, and LDL cholesterol levels. No significant changes were found for A1C or blood pressure. There were also positive changes in daily self-care behaviors practiced per week, including choosing a healthy diet, evenly spacing carbohydrates consumed, exercising, examining feet, and monitoring glucose. On psychosocial measures, patients reported a higher perceived quality of life, less difficulty in engaging in routine physical activity, and less difficulty in using a meal plan. This model would be most useful as an ongoing support group conducted by diabetes educators or trained peers within a community.
The core empowerment-based principles provided the conceptual foundation for all three of the programs described above. These guiding principles, which informed the programs' design and implementation, called for the programs to be patient centered (i.e., focused on concerns and questions introduced by patients), problem based (i.e., used real problems encountered by participants to guide the teaching/learning process), culturally relevant, inclusive of the clinical and psychosocial aspects of living with diabetes, and evidence based.
Patient centered
Problem based
Culturally relevant
Inclusive of psychosocial, behavioral, and clinical issues Although educators and clinicians find it logical to reduce diabetes care and education into a discrete set of topics, such an approach does not bear fidelity to the patients' life experiences with diabetes. Patients perceive their illness as holistic, complex, and dynamic. The three programs described above were based on the lived experiences of program participants as the focus of diabetes education. Patients were encouraged to share and reflect on their own experiences of living with diabetes to identify the problems and priorities addressed during the program.
Evidence based In our experience, many payors, administrators, and health care providers view patient education as monolithic (i.e., they believe that all patient group education programs are roughly equivalent to each other). Perhaps worse, many health providers and policy makers believe that group patient education programs are just a series of didactic lectures. Diabetes educators and behavioral researchers have established that behaviorally oriented group patient education is effective at producing a series of positive changes (at least in the short term) in knowledge, skills, self-management behaviors, and metabolic indexes. The challenge now is to establish an evidence base indicating which theoretical approaches and strategies used in group education are most effective in the short and long terms. A more difficult challenge will be raising awareness among stakeholders who are not educators about the increasing number of dynamic, progressive, and conceptually sophisticated patient education programs being developed and evaluated.
DSME has been delivered and implemented using a variety of methods. Although group-based DSME has generally been found to be equally as effective as individual DSME at improving diabetes-related outcomes, there is some evidence that group programs are more cost effective, result in greater treatment satisfaction, and are slightly better in supporting lifestyle changes. DSME group programs have utilized different patient education theories and strategies that have not been well described in the literature. This article has highlighted strategies that can be used in different health care or community-based settings, including informal learning opportunities, culturally relevant problem-based DSME, and ongoing support for sustaining DSME gains over the long term. Although each of these three programs may have had a different context, format, or primary goal, they all were founded on the empowerment approach to diabetes education and care and designed to meet individual patient needs while taking advantage of the experiences of a group of patients to provide support and assistance to each other.
