The Science of Diabetes Self-Management and Care

The purpose of this article is to present information that will assist the diabetes educator in screening patients with diabetes for risk of osteoporosis and fracture, to offer appropriate treatment options for patients, and to identify potential referrals to other providers for patients with diabetes and increased risk of fracture.

The authors’ class structure incorporates individual meal and exercise planning in the group setting. This study was conducted to (1) determine if class participants can create their own meal and exercise plans, (2) determine if class participants feel they will be able to adhere to their meal and exercise plans, and (3) assess adherence to the plans over time. Subjects were recruited from the classes offered at the Joslin Diabetes Center. Following completion of class, patients completed the evaluation questionnaire. Two and 6 months later, study participants received follow-up questionnaires by phone or mail. Among respondents, 63% were able to determine their own carbohydrate goals, with 95.9% indicating they could adhere to the plan, and 82.8% felt the plan would be easier than previous ones. At 2 and 6 months, respectively, 89% and 92% of the participants felt they were following the meal plan either some or most of the time. One hundred percent of the respondents were able to determine their own exercise plan, with 98% indicating they could adhere to the plan, and 85.7% felt the new plan would be easier than previous ones. At 2 and 6 months, respectively, 70% and 73% felt they were following their exercise plan either some or most of the time. Individualized meal and exercise plans can be successfully created in a group setting.

Purpose

The purpose of this study was to develop and validate a new knowledge scale for patients with type 2 diabetes and poor literacy: the Spoken Knowledge in Low Literacy patients with Diabetes (SKILLD).

Methods

The authors evaluated the 10-item SKILLD among 217 patients with type 2 diabetes and poor glycemic control at an academic general medicine clinic. Internal reliability was measured using the Kuder-Richardson coefficient. Performance on the SKILLD was compared to patient socioeconomic status, literacy level, duration of diabetes, and glycated hemoglobin (A1C).

Results

Respondents’ mean age was 55 years, and they had diabetes for an average of 8.4 years; 38% had less than a sixth-grade literacy level. The average score on the SKILLD was 49%. Less than one third of patients knew the signs of hypoglycemia or the normal fasting blood glucose range. The internal reliability of the SKILLD was good (0.72). Higher performance on the SKILLD was significantly correlated with higher income (r= 0.22), education level (r= 0.36), literacy status (r= 0.33), duration of diabetes (r= 0.30), and lower A1C (r= –0.16). When dichotomized, patients with low SKILLD scores (= 50%) had significantly higher A1C (11.2% vs 10.3%, P< .01). This difference remained significant when adjusted for covariates.

Conclusion

The SKILLD demonstrated good internal consistency and validity. It revealed significant knowledge deficits and was associated with glycemic control. The SKILLD represents a practical scale for patients with diabetes and low literacy.

Purpose

The purpose of this pilot study was to determine the impact of implementing elements of the chronic care model (CCM; decision support, self-management, and delivery system redesign) on providers' diabetes care practices and patient outcomes in a rural practice setting.

Methods

In this pilot study, 104 patients with type 2 diabetes and 6 providers in a rural primary care practice were involved in an intervention that included a certified diabetes educator (CDE) who educated and supported providers on diabetes management and adherence to the American Diabetes Association (ADA) Standards of Care over the year of the project. The CDE also provided diabetes self-management education (DSME) at the office site for 29 of the 104 patients who received their care in the practice. The following variables were evaluated: provider perceived barriers to care and adherence to ADA standards of care and patient A1C, blood pressure, cholesterol, knowledge, and empowerment levels.

Results

Provider adherence to ADA Standards of Care increased significantly across all process measures. Patients who received DSME at point of service in the primary care practice setting gained improvements in knowledge, empowerment, A1C, and high-density lipoprotein cholesterol levels.

Conclusions

Implementing systems to support decision support, selfmanagement education, and delivery system redesign has a positive influence on practices and patient outcomes in outlying rural communities.

Purpose

The purpose of this study is to explore reasons adults with diabetes do not receive at least 2 A1C tests per year as recommended by the American Diabetes Association (ADA).

Methods

ConnectiCare, a regional managed care company based in Farmington, Connecticut, identified adult members with diabetes who did not have a medical claim for an A1C laboratory test from their physician. A questionnaire was sent to 740 randomly selected members asking them to report the number of A1C tests they received in the past 12 months and reasons for not receiving the number of tests recommended by the ADA. After sending an automated telephone reminder to nonrespondents, a 26% (n = 192) response rate was achieved.

Results

Thirty-three percent of respondents (n = 63) reported having diabetes and receiving fewer than 2 A1C tests in the past year. Respondents were equally divided between men and women, with a mean age of 58 years. The primary reasons given for not obtaining at least 2 A1C tests as recommended by the ADA were that respondents were unaware that the test is recommended (49%), not informed of the need for the test by their physician (38%), never heard of the A1C test (33%), and not seen regularly by their physician (19%).

Conclusions

Diabetes self-management education remains an important means of encouraging adherence to important ADA recommendations such as regular A1C testing. Barriers to A1C testing can be addressed in multiple settings, including individual and group education, disease management programs, and physician education.

Purpose

The purpose of this study was to assess the influence of appointment keeping and medication adherence on HbA1c.

Methods

A retrospective evaluation was performed in 1560 patients with type 2 diabetes who presented for a new visit to the Grady Diabetes Clinic between 1991 and 2001 and returned for a follow-up visit and HbA1c after 1 year of care. Appointment keeping was assessed by the number of scheduled intervening visits that were kept, and medication adherence was assessed by the percentage of visits in which self-reported diabetes medication use was as recommended at the preceding visit.

Results

The patients had an average age of 55 years, body mass index (BMI) of 32 kg/m2, diabetes duration of 4.6 years, and baseline HbA1c of 9.1%. Ninety percent were African American, and 63% were female. Those who kept more intervening appointments had lower HbA1c levels after 12 months of care (7.6% with 6-7 intervening visits vs 9.7% with 0 intervening visits). Better medication adherence was also associated with lower HbA1c levels after 12 months of care (7.8% with 76%-100% adherence). After adjusting for age, gender, race, BMI, diabetes duration, and diabetes therapy in multivariate linear regression analysis, the benefits of appointment keeping and medication adherence remained significant and contributed independently; the HbA1c was 0.12% lower for every additional intervening appointment that was kept (P= .0001) and 0.34% lower for each quartile of better medication adherence (P= .0009).

Conclusion

Keeping more appointments and taking diabetes medications as directed were associated with substantial improvements in HbA1c. Efforts to enhance glycemic outcomes should include emphasis on these simple but critically important aspects of patient adherence.

Purpose

The purpose of this article was to describe lessons learned about recruitment and retention of rural African Americans from published literature, the authors’ research, and research experience. Two rural, communitybased research studies with African Americans with diabetes are used to illustrate different issues and strategies in recruitment and retention.

Methods

Relevant MEDLINE articles and clinical studies were reviewed, and the design, implementation, and results of the 2 community-based studies were evaluated. Information from the literature, research results, and sample selection, participation, and attrition experiences were synthesized to determine effective approaches for recruitment and retention.

Results

Research funding, design, and implementation; recruitment methods; culturally competent approaches; caring, trusting provider-patient relationships; incentives; follow-up; and factors in the rural environment emerged as important issues influencing recruitment and retention.

Conclusion

Recruitment and retention of African Americans in rural diabetes research is a significant challenge, and adequate funding should be sought early in the research process. Culturally competent approaches; caring, trusting relationships; incentives; and follow-up are important concepts in successful recruitment, participation, and retention of African Americans. The lessons learned may be applicable to the more widespread issue of recruitment and retention of rural African Americans in diabetes education programs.
