Diabetes nurse case management and motivational interviewing for change (DYNAMIC): results of a 2-year randomized controlled pragmatic trial.

BACKGROUND: The aim of the present study was to determine whether the addition of nurse case managers (NCMs) trained in motivational interviewing (MI) to usual care would result in improved outcomes in high-risk type 2 diabetes patients. METHODS: A 2-year randomized controlled pragmatic trial randomized 545 patients to usual care control (n=313) or those who received the intervention (n=232) with additional practice-embedded NCM care, including MI-guided behavior change counseling. The NCMs received intensive MI training with ongoing fidelity assessment. RESULTS: Systolic blood pressure (SBP) was better in the intervention than usual care group (131 ± 15 vs. 135 ± 18 mmHg, respectively; P<0.05). Improvements were seen in both the control and intervention groups in terms of HbA1c (from 9.1% to 8.0% and from 8.8% to 7.8%, respectively), low-density lipoprotein (LDL; from 127 to 100 mg/dL and from 128 to 102 mg/dL, respectively), and diastolic blood pressure (from 78 to 74 mmHg and from 80 to 74 mmHg, respectively). Depression symptom scores were better in the intervention group. The reduction in diabetes-related distress approached statistical significance. CONCLUSIONS: The NCMs and MI improved SBP and complications screening. The large decrease in HbA1C and LDL in the control group may have obscured any further intervention effect. Although nurses prompted providers for medication titration, strategies to reduce provider clinical inertia may also be needed.

Relationship between Depression and Treatment Satisfaction among Patients with Type 2 Diabetes.

BACKGROUND: Depression has been shown to adversely affect glycemic control. The purpose of this study is to examine the association between depression and treatment satisfaction in patients with diabetes. MATERIALS AND METHODS: Baseline data was collected on 545 patients with poorly controlled type 2 diabetes enrolled in a study that examined the effectiveness of diabetes nurse case managers. Depression was measured using the Center for Epidemiologic Studies Depression (CES-D) questionnaire, and treatment satisfaction, using the Diabetes Treatment Satisfaction Questionnaire (DTSQ). RESULTS: The majority of participants (59%) were female, with a high percentage (41%) of Hispanic/Latino participants with a mean HbA1C of 8.4%. The prevalence of depression in this population was 35.6%. High CES-D scores were associated with elevated levels of HbA1C and LDL cholesterol (p<0.001). The relationship between depression and treatment satisfaction was significant (p<0.001), indicating that as depression increases, treatment satisfaction decreases. DISCUSSION: We identified a significant relationship between depression and treatment satisfaction in this group of poorly controlled type 2 diabetes patients. Although causation cannot be determined, it is possible that patients who are depressed are less likely to be satisfied with their treatment. This could lead to decreased patient adherence, ultimately resulting in poor glycemic control.

How patients with type 2 diabetes mellitus respond to motivational interviewing.

AIM: To determine how patients with type 2 DM feel about a motivational interviewing (MI) intervention designed to promote positive behavior change. METHOD: Qualitative study using focus groups conducted by the same facilitator. SETTING: Family or general internal medicine practice clinics affiliated with an academic medical center and a community general hospital. One site consisted of primarily low income Hispanic patients. PARTICIPANTS: Four focus groups consisting of nineteen adult patients with type 2 diabetes mellitus solicited from a large NIH-funded randomized controlled trial on MI and diabetes. RESULTS: Across and within group analysis was performed on transcripts of the taped interviews. Patient perceptions of standard care were largely negative, with several individuals describing paternalistic and demeaning attitudes. Five themes related to MI emerged: Nonjudgmental Accountability, Being Heard and Responded to as a Person, Encouragement and Empowerment, Collaborative Action Planning and Goal Setting, and Coaching rather than Critiquing. CONCLUSIONS: Some patients with type 2 diabetes are receptive to motivational interviewing which is a provider approach that is more patient-centered and empowering than traditional care.

Development and pilot of a low-literacy diabetes education book using social marketing techniques.

INTRODUCTION: The primary objective of this work was to develop a diabetes education book, to pilot its use, and to evaluate its impact on patient care. The secondary objective was to compare the value of providing only the book to patients versus providing the book along with a brief tutorial given by a nurse on how to use the book. METHODS: A diabetes education book was developed through a social marketing approach. The impact of the book was then tested in a pilot, prospective, randomized controlled trial evaluating diabetes knowledge, emotional distress, self-care behavior, and clinical outcomes in a primary care patient population. The three-arm study randomized one group to usual care (n=33), one group to receive the book alone (n=33), and one group to receive the book with a brief nurse tutorial (n=34). Patients completed surveys at baseline, 4 weeks, 3 months, and 6 months to assess knowledge (Knowledge Questionnaire), self-care behaviors (Summary of Diabetes Self Care Activities [SDSCA] survey), and disease-related distress (Problem Areas in Diabetes [PAID] scale). RESULTS: A patient advocacy committee identified a need for information on basic diabetes knowledge, diet, medications, complications, preparing for a visit, and plans for daily life. Using social marketing with a focus on low literacy, the Penn State Hershey Diabetes Playbook was created. The pilot study showed a trend towards improved knowledge, decreased distress, and improved self-care behaviors in patients who received the book. There was no difference in outcomes in patients who were provided the book alone versus those who received a brief nurse tutorial along with the book. CONCLUSION: Social marketing techniques and low literacy awareness are useful in developing diabetes educational materials.
