Developing a new generation of ongoing: Diabetes self-management support interventions: a preliminary report

PURPOSE

The study examined the feasibility, acceptability, and potential impact of an innovative, community-based, ongoing self-management intervention aimed at enhancing and sustaining self-care behaviors over the long term among urban African Americans with type 2 diabetes.

METHODS

Sixty-two African American men and women completed the study. Participants were invited to attend 24 weekly, consecutive, diabetes self-management support/ education groups. The flow of the weekly group sessions was guided by questions and concerns of the patients. Baseline and 6-month follow-up metabolic functioning, lipid profiles, cardiovascular functioning, and self-care behaviors were assessed.

RESULTS

Ninety percent (n = 56) of the sample attended at least 1 session; 40% attended at least 12 or more sessions. Paired t tests found significant improvements in body mass index (P < .001), total cholesterol (P < .01), high-density lipoprotein (P < .05), and low-density lipoprotein (P < .001). Significant increases were also found for self-care behaviors (P < .05).

CONCLUSIONS

Preliminary evidence suggests that participation in this weekly problem-based, self-management support intervention can yield diabetes-related health benefits.

Implementing an empowerment-based diabetes self-management education program

Diabetes educators are challenged to develop culturally appropriate, integrated, behaviorally based, effective education programs. This article describes the intervention used in a problem-based educational program for urban African Americans with diabetes. The intervention consisted of six 2-hour, weekly group educational and data collection sessions. No lectures were used, and the content was determined by participants' questions and concerns. Culturally tailored written educational materials were also provided.

Empowerment and Self-Management after Weight Loss Surgery

The bariatric surgery health-care professional team are often frustrated and discouraged when patients are unwilling or unable to follow their advice to achieve ideal outcomes after obesity surgery. The acute care model that suffices for other types of surgery is inadequate after a surgery that requires chronic life-long behavioral changes. Practical interventions that facilitate collaborative relationships and foster patient-centered practices are the key to giving up feeling responsible for the choices that patients make, by being responsible to them, and achieving better outcomes.

Using focus groups of older African Americans and Latinos with diabetes to modify a self-care empowerment intervention

OBJECTIVE

To make cultural and age-specific modifications to a self-care empowerment intervention.

DESIGN

Focus groups with self-administered surveys.

SETTING

Two public health diabetes and geriatrics clinic and two senior centers in and around South Los Angeles.

PARTICIPANTS

African Americans and Latinos aged > or = 55 years with diabetes (N=79), and two groups of health educators (N=16).

MAIN OUTCOME MEASURES

After describing the proposed intervention, the focus group facilitators asked participants: 1) whether the community of interest would be interested in the proposed empowerment intervention; 2) why or why not; and 3) how the intervention could be modified to better address the concerns of the study community of interest. All groups were audiotaped, transcribed, and (when appropriate) translated into English. Three independent investigators read all transcripts and completed standardized coding forms for each transcript. In addition, at the end of each focus group, all participants completed a self-administered written survey asking them to rate aspects of the proposed intervention.

RESULTS

Older African Americans and Latinos endorsed the intervention but desired an expanded dietary educational component and identified disability as an important missing content area. Participants rejected the use of an audio learning tool and did not believe that matching group-facilitator sociodemographic characteristics was important as long as facilitators demonstrated cultural competency.

CONCLUSIONS

These findings illustrate a model of participatory research in which researchers and community members work together to develop an empowerment intervention that will meet community needs and will have greater cultural appropriateness. Modifying the intervention in accordance with these findings should enhance the relevance and impact of the self-care intervention.

Evaluating a problem-based empowerment program for African Americans with diabetes: results of a randomized controlled trial

OBJECTIVE

The objective of this study was to evaluate the impact of a problem-based empowerment patient education program specifically tailored for urban African Americans with type 2 diabetes.

RESEARCH DESIGN AND METHODS

The study used a randomized controlled trial (RCT) pretest/post-test design with repeated measures. Patients were randomly assigned to either a six-week intervention group or a six-week wait-listed control group. After completing the six sessions, patients were invited to participate in one of two follow-up conditions; attend a monthly support group or receive a monthly phone call from a nurse. Assessment measures included HbA1C, lipids, blood pressure, weight, self-management behavior and psychosocial adaptation.

RESULTS

Both control and intervention patients showed a broad array of small-to-modest positive changes during the six-week RCT. These gains were maintained or improved upon during the one-year follow-up period. For patients in the two follow-up conditions, a positive correlation was seen between the number of follow-up contacts and their one-year HbA1C values.

CONCLUSIONS

We believe that results of this study can be attributed to volunteer bias, study effects (ie, providing study data on several occasions to patients and their physicians during the one-year study period), and impact of the interventions. However, the study design does not allow us to examine the relative impact of these three factors on the patient improvements seen over the one-year study period.

Dynamics of a scrapie outbreak in a flock of Romanov sheep--estimation of transmission parameters

Knowledge of epidemiological mechanisms and parameters underlying scrapie transmission in sheep flocks remains very limited at present. Here we introduce a method for fitting stochastic transmission models to outbreak data to estimate bounds on key transmission parameters. We apply this method to data describing an outbreak of scrapie in a closed flock of Romanov sheep. The main findings are that the relative infectiousness of infected animals in this outbreak becomes appreciable early into disease incubation and that the mean incubation period is less than 1.5 years. We also find that the data are consistent with a broad range of values for the basic reproduction number R0 and describe how the boundaries of this range depend on assumptions about the mean incubation period and the contribution to transmission of a long-lived environmental reservoir of infectivity.

When do patients and their physicians agree on diabetes treatment goals and strategies, and what difference does it make?

BACKGROUND

For patients with chronic illnesses, it is hypothesized that effective patient-provider collaboration contributes to improved patient self-care by promoting greater agreement on patient-specific treatment goals and strategies. However, this hypothesis has not been tested in actual encounters of patients with their own physicians.

OBJECTIVE

To assess the extent to which patients with type 2 diabetes agree with their primary care providers (PCPs) on diabetes treatment goals and strategies, the factors that predict agreement, and whether greater agreement is associated with better patient self-management of diabetes.

DESIGN

One hundred twenty-seven pairs of patients and their PCPs in two health systems were surveyed about their top 3 diabetes treatment goals (desired outcomes) and strategies to meet those goals. Using several measures to evaluate agreement, we explored whether patient characteristics, such as education and attitudes toward treatment, and patient-provider interaction styles, such as shared decision making, were associated with greater agreement on treatment goals and strategies. We then examined whether agreement was associated with higher patient assessments of their diabetes care self-efficacy and self-management.

RESULTS

Overall, agreement on top treatment goals and strategies was low (all kappa were less than 0.40). In multivariable analyses, however, patients with more education, greater belief in the efficacy of their diabetes treatment, and who shared in treatment decision making with their providers were more likely to agree with their providers on treatment goals or strategies. Similarly, physician reports of having discussed more content areas of diabetes self-care were associated with greater agreement on treatment strategies. In turn, greater agreement on treatment goals and strategies was associated both with higher patient diabetes care self-efficacy and assessments of their diabetes self-management.

CONCLUSION

Although patients and their PCPs in general had poor agreement on goals and strategies for managing diabetes, agreement was associated with higher patient self-efficacy and assessments of their diabetes self-management. This supports the hypothesis that enhancing patient-provider agreement on both overall treatment goals and specific strategies to meet these goals may lead to improved patient outcomes.

Personalized follow-up increases return rate at urban eye disease screening clinics for African Americans with diabetes: results of a randomized trial

OBJECTIVE

To evaluate the effectiveness of using personalized follow-up, as compared to reminder letters, in increasing return rates at urban eye disease screening clinics for African Americans with diabetes, and to identify factors predictive of the patient's likelihood of returning for annual follow-up exams.

RESEARCH DESIGN AND METHODS

All patients attending free community-based retinopathy screening clinics who were advised to return in one year for another diabetes eye evaluation (DEE) were randomized to standard or personalized follow-up interventions. Patients in the standard follow-up group received reminder letters a month before it was time to return for their next annual DEE. Patients in the intensive personalized intervention also received the letters, but those patients who did not call for an appointment within 10 days received a phone call from project staff, encouraging them to return for a DEE.

RESULTS

One hundred thirty-two African Americans with diabetes were randomized to one of the 2 treatments. The return rate for the intensive, personalized follow-up group was 66%, significantly (P=.001) higher than the 35% return rate for the standard follow-up group.

CONCLUSION

This study demonstrated the efficacy of personal contact by telephone in improving return rates for annual DEEs in this population of patients. This finding is consistent with one of the key design principles of the project, which was to establish credible personal relationships with community leaders and patients as a means to maximize the utilization of the eye screening clinics.

Extending backcalculation to analyse BSE data

We review the origins of backcalculation (or back projection) methods developed for the analysis of AIDS (acquired immunodeficiency syndrome) incidence data. These techniques have been used extensively for >15 years to deconvolute clinical case incidence, given knowledge of the incubation period distribution, to obtain estimates of past HIV (human immunodeficiency virus) infection incidence and short-term predictions of future AIDS incidence. Adaptations required for the analysis of bovine spongiform encephalopathy (BSE) incidence included: stratification of BSE incidence by age as well as birth cohort; allowance for incomplete survival between infection and the onset of clinical signs of disease; and decomposition of the age- and time-related infection incidence into a time-dependent feed risk component and an age-dependent exposure/susceptibility function. The most recent methodological developments focus on the incorporation of data from clinically unaffected cattle screened using recently developed tests for preclinical BSE infection. Backcalculation-based predictions of future BSE incidence obtained since 1996 are examined. Finally, future directions of epidemiological analysis of BSE epidemics are discussed taking into account ongoing developments in the science of BSE and possible changes in BSE-related policies.

Are residents more comfortable than faculty members when addressing sociocultural diversity in medicine?

PURPOSE

Sociocultural medicine is a growing curricular area in medical education. Because faculty members and residents will teach these curricula and model these skills in patient care, it is important to assess their attitudes toward diversity. This study examined faculty members' and residents' attitudes toward sociocultural issues in medicine.

METHOD

In November 2000, 198 physicians from the Department of Pediatrics at the University of Michigan Medical School completed a questionnaire on demographics and sociocultural attitudes in medicine while they attended a department-wide retreat on cultural competency. A factor analysis of the sociocultural attitudes measure yielded five dimensions accounting for 70% of the variance. These factors included sexual orientation, diversity in professional functions, discussing race/ethnicity in teaching forums, clinical skills, and alternative medicine.

RESULTS

Significant differences were found between faculty members and residents for sexual orientation issues (t = 2.76, p <.01) and alternative medicine (t = 2.84, p <.01), with residents endorsing greater comfort in these areas of patient care. When controlling for demographic/background variables, group differences disappeared. Past exposure to multiculturalism emerged as a significant predictor for both sociocultural attitude dimensions.

CONCLUSIONS

Findings suggested while residents felt more comfortable than faculty members did with sexual orientation and alternative medicine issues in medicine, attitudes may have been related more to previous diversity education than to seniority of the physician. Integrating diversity education within departments and across the medical education continuum likely benefits all physicians. In the area of sociocultural medicine, both faculty members and residents can offer perspectives valuable to medical students, colleagues, and the larger medical community.

Measuring perceptions of diabetes-related concepts: a preliminary study

PURPOSE

This pilot study explored health professionals' and patients' perceptions of diabetes through the development of the Diabetes Semantic Differential Scales (DSDS). These scales evaluate the meaning of diabetes-related concepts.

METHODS

Health professionals (n = 39) attending a CME course completed the health professional version of the DSDS. Patients (n = 70) completed the patient version of the DSDS.

RESULTS

The reliability of the DSDS was supported. The scale scores of health professionals, African American patients, and Caucasian patients, examined initially by one-way analyses of variance, showed significant differences among the groups for 4 of the 18 diabetes concepts. Effect sizes were also examined among these groups. For 7 concepts, there was a significant practical difference between the perceptions of the health professionals and the African American patients. For the Caucasian patients, differences were noted for 6 concepts.

CONCLUSIONS

There are 3 primary inferences from this pilot study. First, health professionals and patients are likely to hold different perceptions of key diabetes concepts. Second, the concepts on which professionals and patients differ are not always what one would expect. Third, health professionals should clarify patients' understanding of diabetes to minimize the potential for miscommunication.

Changing office practice and health care systems to facilitate diabetes self-management

Diabetes is a self-managed disease for which patients provide 99% of their own care. For patients to succeed as diabetes self-managers, they need office practices and health care systems that can prepare and support them in their diabetes self-management efforts over the long term. In order to provide effective diabetes education and ongoing support, office practices and health care systems will have to fundamentally redefine the roles of health professionals and patients with diabetes, and redesign practices and systems to allow for effective long-term self-management education and support. Although it is difficult for both people and systems to change, change is essential if we are going to provide self-management support for the majority of patients suffering from this serious chronic disease.

Faculty development for educational leadership and scholarship

The Medical Education Scholars Program (MESP) at the University of Michigan Medical School is designed to develop leaders in medical education. The program's goals are to enable faculty to provide curriculum direction, improved teaching, educational research, and development, and institutional leadership at all levels of medical education. This one-year program uses a variety of educational methods and provides a broad curriculum in educational theory, assessment and evaluation, research design and methods, teaching-skills development, and educational leadership. Faculty are admitted on a competitive basis and one half-day per week of release time is funded as part of the program. Salient outcomes of the program (promotions, educational research and development, curriculum leadership, and educational scholarship) were measured in a pre- and post-program design in which each scholar acted as his or her own control. There were major increases in promotions and educational awards, new educational responsibilities, and new educational programs. A particularly important outcome was the emergence of educational scholarship in the professional portfolios of the program scholars in the form of peer-reviewed presentations and publications and educational grant funding. A cost-outcome analysis indicates that these multi-year outcomes were obtained from a one-time investment of approximately $21,000 per graduating scholar. This evaluation indicates that intensive faculty development programs can have measurable impacts on the careers of the participants and the institutional environment.

Conducting community-based, culturally specific, eye disease screening clinics for urban African Americans with diabetes

The purpose of this study was to evaluate the need for, and efficacy of, community-based culturally specific eye disease screening clinics for urban African Americans with diabetes. The study employed a variety of culturally specific methods in the design and performance of 43 community-based eye disease screening clinics in southeastern Michigan. One thousand, thirty-seven subjects were recruited for the study. Of that number, 817 identified themselves as African Americans and are the focus of this report. Of the 817 African-American patients screened, 84 (10%) needed to be examined by an ophthalmologist immediately (< 30 days), and 180 (22%) needed to be examined soon (within 1 to 3 months), while 544 (67%) were advised to return for another exam a year later. The project demonstrated that it was possible to use culturally specific techniques to identify a significant number of urban African Americans with diabetes in need of eye screening and treatment. However, lack of health insurance proved to be the primary barrier to receiving needed treatment. Although the project was successful, it is not a solution to what is essentially a health systems problem, ie, inadequate access to appropriate diabetes care for a significant number of our population.

Patterns of antiretroviral use in the United States of America: analysis of three observational databases

OBJECTIVE

To characterize patterns of antiretroviral use in HIV-infected patients and explore variation by patient characteristics and disease stage.

METHODS

Three large patient databases recording information derived from routine clinical attendance were analyzed: HIV Insight (n = 10 873), Target Management Services (n = 2226) and Clinical Partners (n = 1505). Each database records the dates of starting and stopping individual antiretroviral agents over time, measurements of CD4 T-cell counts and HIV-RNA levels at approximately 6-monthly intervals, and the demographic characteristics of patients. The number, frequency and duration of different antiretroviral combinations over time and their relationship to stage of HIV-disease and demographic characteristics were explored.

RESULTS

Over 2000 different combinations of antiretroviral agents are recorded. From 1987 onwards, the use of zidovudine increased, with 23% of patients receiving monotherapy by 1990. The majority of treated patients remained on monotherapy until the introduction of highly active antiretroviral therapy (HAART) in 1996. By 1999, the standard of care was HAART, with 84% of patients beginning antiretroviral therapy with HAART. Those of African American race (odds ratio 0.59) and funded by Medicaid (odds ratio 0.72) were significantly less likely to begin antiretroviral therapy on HAART. Until 1995, there was a significant decrease in CD4 T-cell count when starting antiretroviral therapy. No significant trend was observed in either CD4 T-cell count or viral load after this time. Those starting on HAART therapies were significantly less likely to stop or switch regimens than those on nucleoside reverse transcriptase inhibitor (NRTI)-only therapies (P < 0.001).

CONCLUSIONS

Complex patterns of antiretroviral treatment are observed in this large population. Changes over time mirror the introduction of the new antiretroviral agents.
