The impact of social support on outcomes in adult patients with type 2 diabetes: a systematic review.

Diabetes is one of the fastest growing chronic diseases globally and in the United States. Although preventable, type 2 diabetes accounts for 90 % of all cases of diabetes worldwide and continues to be a source of increased disability, lost productivity, mortality, and amplified health-care costs. Proper disease management is crucial for achieving better diabetes-related outcomes. Evidence suggests that higher levels of social support are associated with improved clinical outcomes, reduced psychosocial symptomatology, and the adaptation of beneficial lifestyle activities; however, the role of social support in diabetes management is not well understood. The purpose of this systematic review is to examine the impact of social support on outcomes in adults with type 2 diabetes.

Association between spirituality and depression in adults with type 2 diabetes.

PURPOSE: The purpose of the study was to examine the association between spirituality and depression among patients with type 2 diabetes. METHODS: This study included 201 adult participants with diabetes from an indigent clinic of an academic medical center. Participants completed validated surveys on spirituality and depression. The Daily Spiritual Experience (DSE) Scale measured a person's perception of the transcendent (God, the divine) in daily life. The Center for Epidemiologic Studies-Depression scale assessed depression. Linear regression analyses examined the association of spirituality as the predictor with depression as the outcome, adjusted for confounding variables. RESULTS: Greater spirituality was reported among females, non-Hispanic blacks, those with lower educational levels, and those with lower income. The unadjusted regression model showed greater spirituality was associated with less depression. This association was mildly diminished but still significant in the final adjusted model. Depression scores also increased (greater depression risk) with females and those who were unemployed but decreased with older age and non-Hispanic black race/ethnicity. CONCLUSIONS: Treatment of depression symptoms may be facilitated by incorporating the spiritual values and beliefs of patients with diabetes. Therefore, faith-based diabetes education is likely to improve self-care behaviors and glycemic control.

Effect of perceived control on quality of life in indigent adults with type 2 diabetes.

PURPOSE: To examine the relationship between perceived control of diabetes and physical and mental health components of quality of life in indigent adults with diabetes. METHODS: The primary variables, perceived control of diabetes and quality of life, were evaluated among188 patients from a low-income clinic located at an academic medical center. Over a 12-month period, consenting subjects completed the surveys to assess perceived control of diabetes and health-related quality of life. Sociodemographic factors (age, gender, race/ethnicity, income, education, employment, marital status, and insurance status) were collected as well as clinical factors like comorbid conditions and use of insulin therapy. Multiple linear regression models were used to assess the independent association of perceived control on quality of life. RESULTS: The sample largely comprised middle-aged women with diabetes, a majority being black; nearly two-thirds had at least a high school education and almost three-quarters were unemployed. Mean quality of life scores were generally below national population means. Correlation results indicated a positive relationship between perceived control and both physical and mental quality of life. Regression results supported the positive association between perceived control and quality of life, even when controlling for sociodemographics and comorbidity in the final model. CONCLUSION: Increasing perceived control, perhaps by a combination of education and skills building (ie, self-efficacy), will result in higher perceived quality of life (QOL) among disadvantaged populations with diabetes.

Disparities in diabetes self-management and quality of care in rural versus urban veterans.

BACKGROUND: There are distinct geographic differences in diabetes-related morbidity and mortality; however, data regarding self-management and clinical outcomes are limited. This study examined diabetes care among veterans residing in rural versus urban areas. METHODS: A national data set was analyzed based on 10,570 veterans with type 2 diabetes. Residence was determined according to US census-based metropolitan statistical area. Primary outcomes were self-management behaviors (lifestyle and self-monitoring) and quality of care indicators (provider visits, laboratory monitoring and preventive measures). Multivariate analyses were done using STATA v10 to assess the independent effect of veteran residence on each outcome measure and to account for the complex survey design. RESULTS: Among veterans with diabetes, 21.4% were rural residents. Compared to urban veterans, rural veterans had significantly lower education, less annual income and less received diabetes education (P = .002). The final regression model showed that daily foot self-check was the only self-management behavior significantly higher among rural veterans (odds ratio 1.36, 95% confidence interval 1.10-1.70). Provider-based quality of care was not significantly different between groups. CONCLUSIONS: Diabetes self-foot care was significantly better among rural veterans than their urban counterparts, but quality of care was equivalent. This suggests that clinical diabetes care among veterans is uniform; however, greater efforts for patient education and support in diabetes self-management are needed to improve outcomes.

Effectiveness of technology-assisted case management in low income adults with type 2 diabetes (TACM-DM): study protocol for a randomized controlled trial.

BACKGROUND: An estimated 1 in 3 American adults will have diabetes by the year 2050. Nationally, South Carolina ranks 10th in cases of diagnosed diabetes compared to other states. In adults, type 2 diabetes (T2DM) accounts for approximately 90-95% of all diagnosed cases of diabetes. Clinically, provider and health system factors account for < 10% of the variance in major diabetes outcomes including hemoglobin A1c (HbA1c), lipid control, and resource use. Use of telemonitoring systems offer new opportunities to support patients with T2DM while waiting to be seen by their health care providers at actual office visits. A variety of interventions testing the efficacy of telemedicine interventions have been conducted, but the outcomes have yielded equivocal results, emphasizing the shortage of controlled, randomized trials in this area. This study provides a unique opportunity to address this gap in the literature by optimizing two strategies that have been shown to improve glycemic control, while simultaneously implementing clinical outcomes measures, using a sufficient sample size, and offering health care delivery to rural, underserved and low income communities with T2DM who are seen at Federally Qualified Health Centers (FQHCs) in coastal South Carolina. METHODS: We describe a four-year prospective, randomized clinical trial, which will test the effectiveness of technology-assisted case management in low income rural adults with T2DM. Two-hundred (200) male and female participants, 18 years of age or older and with an HbA1c ≥ 8%, will be randomized into one of two groups: (1) an intervention arm employing the innovative FORA system coupled with nurse case management or (2) a usual care group. Participants will be followed for 6-months to ascertain the effect of the interventions on glycemic control. Our primary hypothesis is that among indigent, rural adult patients with T2DM treated in FQHC's, participants randomized to the technology-assisted case management intervention will have significantly greater reduction in HbA1c at 6 months of follow-up compared to usual care. DISCUSSION: Results from this study will provide important insight into the effectiveness of technology-assisted case management intervention (TACM) for optimizing diabetes care in indigent, rural adult patients with T2DM treated in FQHC's.

Rural/urban variations in diabetes self-care and quality of care in a national sample of US adults with diabetes.

PURPOSE: The purpose of this study was to examine differences in diabetes self-care and provider-based quality-of-care indicators between rural and urban dwellers in a nationally representative sample of adults with diabetes. METHODS: Data were analyzed on 52,817 individuals with type 2 diabetes from the 2007 Behavioral Risk Factor Surveillance Survey. Rural and urban residence was based on metropolitan statistical area. Self-care behaviors (nutrition, physical activity, self-monitoring) and quality-of-care indicators (clinical visits, glycemic control, preventive measures) were self-reported. Logistic regression analyses were done using STATA 10 to assess the independent effect of rural/urban residence on self-care and each quality measure and to account for the complex survey design. RESULTS: Rural residents comprised 21% of the sample and were less likely to receive diabetes education (57% vs 51%, P < .001). The final adjusted model showed that foot self-checks (odds ratio, 1.42; 95% confidence interval, 1.27-1.59) and blood glucose testing at least once daily (odds ratio, 1.14; 95% confidence interval, 1.02-1.26) were significantly higher among rural individuals. Provider-based quality of care was not significantly different by rural/urban residence. CONCLUSION: Contrary to what has been reported, there were no significant differences in diabetes quality of care between rural and urban dwellers. In addition, rural dwellers appeared to have better self-care behaviors than urban dwellers. Further research is needed to clarify the reasons for these findings.

Variation in quality of care indicators for diabetes in a national sample of veterans and non-veterans.

BACKGROUND: Veterans have a disproportionately higher burden of type 2 diabetes. It is unclear whether veterans with diabetes have better self-care behaviors or receive better quality of care than non-veterans. The objective was to examine differences in diabetes care between veterans and non-veterans. METHODS: Data analysis was performed with respondents from the 2003 Behavioral Risk Factor Surveillance Survey (n = 21,111 with diabetes). Veterans were those who reported U.S. military service and no longer on active duty. Self-care behaviors included daily fruit and vegetable intake, physical activity level, self-foot checks, and home glucose testing. Quality of care indicators included provider actions over the past 12 months (2+ office visits, 2+ glycosylated hemoglobin checks, 1+ foot exams, 1+ dilated eye exams, daily aspirin use, receiving flu or pneumonia vaccine). Multiple logistic regression using STATA version 10 (Stata Corp., College Station, TX) analyzed differences by veteran status on each quality indicator, controlling for sociodemographics and diabetes education. RESULTS: Veterans comprised 14.2% of the sample, and 12.4% had diabetes compared to 6.7% of non-veterans. In final adjusted models, veterans were significantly more likely to check their feet (odds ratio [OR] 1.33, 95% confidence interval [CI] 1.09, 1.64), get a dilated eye exam (OR 1.36, 95% CI 1.11, 1.66), receive aspirin (OR 1.31, 95% CI 1.04, 1.65), get a flu shot (OR 1.32, 95% CI 1.09, 1.61), and ever get a pneumonia shot (OR 1.38, 95% CI 1.12, 1.70). CONCLUSIONS: Veterans appear to have better self-care behaviors and receive better preventive care than non-veterans. However, future efforts need to focus on boosting self-care to improve diabetes outcomes.

Effect of Veterans Administration use on indicators of diabetes care in a national sample of veterans.

BACKGROUND: Diabetes poses a serious health burden, of which veterans have a disproportionate share. Few data exist regarding differences in self-care behaviors and provider-based quality of care indicators among a large sample of veterans. The objective of this study was to determine the effect of Veterans Affairs (VA) use on diabetes quality of care indicators among veterans. METHODS: A cross-sectional analysis was done on data from 36,525 veterans in the 2003 Behavioral Risk Factor Surveillance Survey. VA use was defined as receiving some or all health care from a VA facility in the previous 12 months. Diabetes quality indicators such as two or more provider visits, two or more hemoglobin A1c tests, and flu and pneumonia shots were compared between VA users and non-VA users. The independent effect of VA use on each quality indicator was analyzed with multiple regression using STATA version 10 (Stata Press, College Station, TX) to account for the complex survey design and yield population estimates. RESULTS: Among veterans with diabetes, 26.8% were VA users. The only significant difference between VA users and non-VA users was that VA users were significantly more likely to check their feet one or more times daily (75.7% vs. 68.5%, P = 0.015). In final adjusted models, VA users were at least twice as likely as non-VA users to have foot exams by a provider (odds ratio 2.59) and receive flu and pneumonia shots (odds ratio 2.30 and 2.05, respectively). VA users were also more likely to have two or more provider visits, dilated eye exams, and two or more hemoglobin A1c tests than non-VA users. CONCLUSIONS: Key quality indicators for diabetes care were better among veterans getting some or all of their care from VA facilities, suggesting more effective care strategies. However, interventions should identify and perpetuate excellent self-care behaviors to more substantially impact adverse diabetes-related outcomes.

Rationale and design: telephone-delivered behavioral skills interventions for Blacks with Type 2 diabetes.

BACKGROUND: African Americans with Type 2 diabetes (T2DM) have higher prevalence of diabetes, poorer metabolic control, and greater risk for complications and death compared to American Whites. Poor outcomes in African Americans with T2DM can be attributed to patient, provider, and health systems level factors. Provider and health system factors account for <10% of variance in major diabetes outcomes including hemoglobin A1c (HbA1c), lipid control, and resource use. Key differences appear to be at the patient level. Of the patient level factors, consistent differences between African Americans and American Whites with T2DM have been found in diabetes knowledge, self-management skills, empowerment, and perceived control. A variety of interventions to improve diabetes self-management have been tested including: 1) knowledge interventions; 2) lifestyle interventions; 3) skills training interventions; and 4) patient activation and empowerment interventions. Most of these interventions have been tested individually, but rarely have they been tested in combination, especially among African Americans who have the greatest burden of diabetes related complications. This study provides a unique opportunity to address this gap in the literature. METHODS/DESIGN: We describe an ongoing four-year randomized clinical trial, using a 2 x 2 factorial design, which will test the efficacy of separate and combined telephone-delivered, diabetes knowledge/information and motivation/behavioral skills training interventions in high risk African Americans with poorly controlled T2DM (HbA1c >or= 9%). Two-hundred thirty-two (232) male and female African-American participants, 18 years of age or older and with an HbA1c >or= 9%, will be randomized into one of four groups for 12-weeks of phone interventions: (1) an education group, (2) a motivation/skills group, (3) a combined group or (4) a usual care/general health education group. Participants will be followed for 12-months to ascertain the effect of the interventions on glycemic control. Our primary hypothesis is that among African Americans with poorly controlled T2DM, patients randomized to the combined diabetes knowledge/information and motivation/behavioral skills training intervention will have significantly greater reduction in HbA1c at 12 months of follow-up compared to the usual care/general health education group. DISCUSSION: Results from this study will provide important insight into how best to deliver diabetes education and skills training in ethnic minorities and whether combined knowledge/information and motivation/behavioral skills training is superior to the usual method of delivering diabetes education for African Americans with poorly controlled T2DM.
