Purpose The purpose of this comparative effectiveness study is to compare diabetes self-management support ( DSMS ) approaches and determine who can be most effective in helping patients maintain/improve clinical  outcomes  ,  self-care behaviors , distress , and satisfaction following  diabetes self-management education ( DSME )  delivered in primary care . Methods After receiving DSME , 141 participants were r and omized to receive DSMS delivered by a trained supporter :  educator , peer , practice staff , or usual education during a 6-month follow-up period . DSMS groups were compared to determine which supporter helped participants to maintain/improve A1C , blood pressure , lipids , weight , self-care , and distress . DSMS satisfaction was also examined . Results There was a significant improvement in A1C , empowerment , aspects of self-care , and distress following DSME at 6 weeks . Those in the educator DSMS group best sustained improved A1C while those in the other DSMS groups maintained glycemic improvements but began to show trends toward worsening . No significant differences or clear trends were seen in other clinical , behavioral , or psychosocial outcomes . The Program Reinforcement Impacts Self-Management ( PRISM ) study demonstrates that following DSME , participants maintained improved glycemia , lipid , weight , and self-care behaviors and reductions in distress throughout the delivery of DSMS interventions regardless of DSMS supporter . All of the participants reported satisfaction with DSMS . Conclusions These findings reaffirm the critical role of educators but suggest that others may serve as DSMS supporters . Results suggest that DSME delivered in primary care is effective and multiple DSMS agents are reasonable . As patient-centered self-management approaches are being explored in primary care , delivery of DSME and DSMS becomes paramount This meta- analysis assessed how successfully Diabetes Self-Management Education ( DSME ) interventions help people with type 2 diabetes achieve and maintain healthy blood glucose levels . We included 52 DSME programs with 9,631 participants that reported post-intervention A1c levels in r and omized controlled trials . The training conditions result ed in significant reductions in A1c levels compared to control conditions . However , the impact of intervention was modest shifting of only 7.23 % more participants from diabetic to pre-diabetic or normal status , relative to the control condition . Most intervention participants did not achieve healthy A1c levels . Further , few DSME studies assessed long-term maintenance of A1c gains . Past trends suggest that gains are difficult to sustain over time . Our results suggested that interventions delivered by nurses were more successful than those delivered by non-nursing personnel . We suggest that DSME programs might do better by going beyond procedural interventions . Most DSME programs relied heavily on rules and procedures to guide decisions about diet , exercise , and weight loss . Future DSME may need to include cognitive self-monitoring , diagnosis , and planning skills to help patients detect anomalies , identify possible causes , generate corrective action , and avoid future barriers to maintaining healthy A1c levels . Finally , comprehensive descriptions of DSME programs would advance future efforts AIM To determine whether glycemic control is improved when motivational interviewing ( MI ) , a patient-centered behavior change strategy , is used with diabetes self management education ( DSME ) as compared to DSME alone . METHODS poorly controlled type 2 diabetes ( T2DM ) patients ( n=234 ) were r and omized into 4 groups : MI+DSME or DSME alone , with or without use of a computerized summary of patient self management barriers . We compared HbA1c changes between groups at 6 months and investigated mediators of HbA1c change . RESULTS study patients attended the majority of the four intervention visits ( mean 3.4 ) , but drop-out rate was high at follow-up research visits ( 35 % ) . Multiple regression showed that groups receiving MI had a mean change in HbA1c that was significantly lower ( less improved ) than those not receiving MI ( t=2.10 ; p=0.037 ) . Mediators of HbA1c change for the total group were diabetes self-care behaviors and diabetes distress ; no between-group differences were found . CONCLUSIONS DSME improved blood glucose control , underlining its benefit for T2DM management . However , MI+DSME was less effective than DSME alone . Overall , weak support was found for the clinical utility of MI in the management of T2DM delivered by diabetes educators Background Type 2 diabetes ( T2D ) is a significant public health problem , with U.S. Pacific Isl and er communities — such as the Marshallese — bearing a disproportionate burden . Using a community-based participatory approach ( CBPR ) that engages the strong family-based social infrastructure characteristic of Marshallese communities is a promising way to manage T2D . Objectives Led by a collaborative community-academic partnership , the Family Model of Diabetes Self-Management Education ( DSME ) aim ed to change diabetes management behaviors to improve glycemic control in Marshallese adults with T2D by engaging the entire family . Design To test the Family Model of DSME , a r and omized , controlled , comparative effectiveness trial with 240 primary participants was implemented . Half of the primary participants were r and omly assigned to the St and ard DSME and half were r and omly assigned to the Family Model DSME . Both arms received ten hours of content comprised of 6–8 sessions delivered over a 6–8 week period . Methods The Family Model DSME was a cultural adaptation of DSME , whereby the intervention focused on engaging family support for the primary participant with T2D . The St and ard DSME was delivered to the primary participant in a community-based group format . Primary participants and participating family members were assessed at baseline and immediate post-intervention , and will also be assessed at 6 and 12 months . Summary The Family Model of DSME aim ed to improve glycemic control in Marshallese with T2D . The utilization of a CBPR approach that involves the local stakeholders and the engagement of the family-based social infrastructure of Marshallese communities increase potential for the intervention 's success and sustainability OBJECTIVE To evaluate the efficacy of ongoing group based diabetes self-management education ( DSME ) for patients with type 2 diabetes . METHODS 146 patients were r and omised to either group education or waiting list control . Primary outcomes were A1C and patient activation measured with patient activation measure ( PAM ) . RESULTS There were no differences in the primary outcomes between the groups at 12 months , but the control group had an increase in A1C of 0.3 % points during follow-up . Diabetes knowledge and some self-management skills improved significantly in the intervention group compared to the control group . A sub group analysis was conducted for the quartile with the highest A1C at baseline ( > 7.7 , n=18 in both groups ) . There were significant improvements within the intervention group at 12 month follow-up for both A1C and PAM and a trend for better outcome in the intervention group compared to the control . CONCLUSIONS The locally developed ongoing diabetes self-management education programs prevented an increase in A1C and can have an effect on A1C in patients with higher A1C level . PRACTICE IMPLICATION S Locally developed programs may be less effective than programs developed for studies Purpose The purpose of this study is to test the feasibility of conducting a community-based r and omized controlled trial evaluating a culturally tailored community-based group diabetes self-management education ( DSME ) program among rural African Americans . Methods Thirty-two African American rural adults with type 2 diabetes were recruited and 25 adults were retained and participated in an interventional study design ed to test the effectiveness of the “ Taking Care of Sugar ” DSME program for the 2-year follow-up . Participants were selected from rural central Virginia . Primary outcomes variables included average blood sugar levels , cardiovascular risk factors , and general physical and mental health . These outcomes were assessed at baseline , 3 months , 6 months , and 12 months post baseline . Results From baseline to 3-month follow-up assessment , participants exhibited significant improvement on several physiological and behavioral measures . Given the small sample size , hypothesis testing was limited . Results show change from baseline over time , illustrating that the primary outcome of A1C decreased , although not significant . Additionally , participants reported more knowledge about diabetes self-management and personal care skills ( ie , exercise and foot care ) that persisted over time . The feasibility of the culturally tailored DSME was established , and participation with the program was high . Conclusions A community-based group DSME program using storytelling is feasible . This research will help to inform clinicians and health policymakers as to the types of interventions that are feasible in a larger rural population . If such a program is carried out , we can improve knowledge , reduce complications , and improve quality of life among rural African Americans Purpose The purpose of this pilot study was to evaluate a culturally tailored intervention for rural African Americans . Social Cognitive Theory provided the framework for the study . Methods Twenty-two participants were recruited and r and omly assigned to either Group or Individual diabetes self-management ( DSME ) . Group DSME included story-telling , h and s-on activities , and problem-solving exercises . Individual DSME sessions focused on goal - setting and problem-solving strategies . Sessions were offered in an accessible community center over a 10-week period . Results Outcomes included glycosylated hemoglobin ( A1C ) , self-care actions , self-efficacy level , goal attainment , and satisfaction with DSME . Participants in both Group and Individual DSME improved slightly over the 3-month period in self-care activities , A1C level , and goal attainment . Although differences were not statistically significant , trends indicate improved scores on dietary actions , foot care , goal attainment , and empowerment for those experiencing Group DSME . Conclusions The culturally tailored approach was well received by all participants . Improvements among those receiving Individual DSME may indicate that brief sessions using a culturally tailored approach could enhance self-care and glycemic control . Additional testing among more participants over a longer time period is recommended Purpose The purpose of this study was to determine the impact of diabetes self-management education ( DSME ) in improving processes and outcomes of diabetes care as measured by a five component diabetes bundle and HbA1c , in individuals with type 2 diabetes mellitus ( T2DM ) . Methods A retrospective analysis was performed for adult T2DM patients who received DSME training in 2011–2012 from an accredited American Diabetes Association center at Intermountain Healthcare ( IH ) and had an HbA1c measurement within the prior 3 months and 2–6 months after completing their first DSME visit . Control patients were selected from the same clinics as case- patients using r and om number generator to achieve a 1 to 4 ratio . Case and control patients were included if 1 ) pre-education HbA1c was between 6.0%–14.0 % ; 2 ) their main provider was a primary care physician ; 3 ) they met the national Healthcare Effectiveness Data and Information Set criteria for inclusion in the IH diabetes registry . The IH diabetes bundle includes retinal eye exam , nephropathy screening or prescription of angiotensin converting enzyme or angiotensin receptor blocker ; blood pressure < 140/90 mmHg , LDL < 100 mg/dL , HbA1c < 8.0 % . Results DSME patients had a significant difference in achievement of the five element IH diabetes bundle and in HbA1c % compared to those without DSME . After adjusting for possible confounders in a multivariate logistic regression model , DSME patients had a 1.5 fold difference in improvement in their diabetes bundle and almost a 3 fold decline in HbA1c compared to the control group . Conclusion St and ardized DSME taught within an IH American Diabetes Association center is strongly associated with a substantial improvement in patients meeting all five elements of a diabetes bundle and a decline in HbA1c beyond usual care . Given the low operating cost of the DSME program , these results strongly support the value adding benefit of this program in treating T2DM patients Mindful eating may be an effective intervention for increasing awareness of hunger and satiety cues , improving eating regulation and dietary patterns , reducing symptoms of depression and anxiety , and promoting weight loss . Diabetes self-management education ( DSME ) , which addresses knowledge , self-efficacy , and outcome expectations for improving food choices , also may be an effective intervention for diabetes self-care . Yet few studies have compared the impact of mindful eating to a DSME-based treatment approach on patient outcomes . Adults 35 to 65 years old with type 2 diabetes for ≥1 year not requiring insulin therapy were recruited from the community and r and omly assigned to treatment group . The impact of a group-based 3-month mindful eating intervention ( MB-EAT-D ; n = 27 ) to a group-based 3-month DSME “ Smart Choices ” ( SC ) intervention ( n = 25 ) postintervention and at 3-month follow-up was evaluated . Repeated- measures ANOVA with contrast analysis compared change in outcomes across time . There was no significant difference between groups in weight change . Significant improvement in depressive symptoms , outcome expectations , nutrition and eating-related self-efficacy , and cognitive control and disinhibition of control regarding eating behaviors occurred for both groups ( all p < .0125 ) at 3-month follow-up . The SC group had greater increase in nutrition knowledge and self-efficacy than the MB-EAT-D group ( all p < .05 ) at 3-month follow-up . MB-EAT-D had significant increase in mindfulness , whereas the SC group had significant increase in fruit and vegetable consumption at study end ( all p < .0125 ) . Both SC and MB-EAT-D were effective treatments for diabetes self-management . The availability of mindful eating and DSME-based approaches offers patients greater choices in meeting their self-care needs BACKGROUND Ongoing self-management improves outcomes for those with Type 2 diabetes ( T2D ) ; however , there are many barriers to patients receiving assistance in this from the healthcare system and peers . Findings from our pilot study showed that a virtual diabetes community on the Internet with real-time interaction among peers with T2D- and with healthcare professionals-is feasible and has the potential to influence clinical and psychosocial outcomes . OBJECTIVE The purpose of this article is to present the protocol for the Diabetes Learning in Virtual Environments ( LIVE ) trial . PROTOCOL Diabetes LIVE is a two-group , r and omized controlled trial to compare effects of a virtual environment and traditional Web site on diet and physical activity . Our secondary aims will determine the effects on metabolic outcomes ; effects of level of engagement and social network formation in LIVE on behavioral outcomes ; potential mediating effects of changes in self-efficacy ; and diabetes knowledge , diabetes-related distress , and social support on behavior change and metabolic outcomes . We will enroll 300 subjects at two sites ( Duke University/Raleigh-Durham , NC and New York University/New York , NY ) who have T2D and do not have serious complications or comorbidities . Those r and omly assigned to the intervention group have access to the LIVE site where they can find information , synchronous classes with diabetes educators , and peer support to enhance self-management . Those in the control group have access to the same informational and educational content in a traditional asynchronous Web format . Measures of self-management , clinical outcomes , and psychosocial outcomes are assessed at baseline and 3 , 6 , 12 , and 18 months . DISCUSSION Should LIVE prove effective in improved self-management of diabetes , similar interventions could be applied to other prevalent chronic diseases . Innovative programs such as LIVE have potential for improving healthcare access in an easily disseminated alternative model of care that potentially improves the reach of self-management training and support Aims : This paper aims to explore the effect of the social network based intervention Powerful Together with Diabetes on diabetes self-management among socioeconomically deprived patients . This 10-month group intervention targeting patients and significant others aim ed to improve self-management by stimulating social support and diminishing social influences that hinder self-management . Methods : This intervention was evaluated in a quasi-experimental study using a mixed methods approach . Of 131 socioeconomically deprived patients with suboptimal glycaemic control , 69 were assigned to the  intervention  group and 62 to the  control group ( st and ard diabetes education ) . 27 qualitative in-depth interviews with the participants and 24 with their group leaders were held to study the subjective impact of the intervention . Further , self-management behaviours ( medication adherence , diet and physical activity ) were assessed at baseline , 10 and 16 months . Data were analysed using framework analyses and a linear mixture model . Results : Qualitative data showed that the intervention group had a better underst and ing of the way self-management influences diabetes . The intervention group showed more complex self-management behaviours , such as planning ahead , seeking adequate food and physical activity alternatives , and consistently taking their diabetes into consideration when making choices . In participants with complete follow-up data , we found a significant increase in physical activity in the intervention group ( 3.78 vs. 4.83 days ) and no changes in medication adherence and diet . Conclusions : This study indicates that an intensive support group and simultaneously involving significant others might improve diabetes self-management behaviours among socioeconomically deprived patients . More studies are needed to justify further implementation of the intervention . This study is registered in the Dutch Trial Register NTR1886 . http://www.trialregister.nl/trialreg/admin/ rct Background Diabetes specific emotional problems interfere with the dem and ing daily management of living with type 2 diabetes mellitus ( T2DM ) . Possibly , offering direct feedback on diabetes management may diminish the presence of diabetes specific emotional problems and might enhance the patients ' belief they are able to manage their illness . It is hypothesized that self-monitoring of glucose in combination with an algorithm how and when to act will motivate T2DM patients to become more active participants in their own care leading to a decrease in diabetes related distress and an increased self-efficacy . Methods and design Six hundred patients with T2DM ( 45 ≤ 75 years ) who receive care in a structured diabetes care system , HbA1c ≥ 7.0 % , and not using insulin  will be recruited and r and omized into 3 groups ; Self-monitoring of Blood Glucose ( SMBG ) , Self-monitoring of Urine Glucose ( SMUG ) and usual care ( n = 200 per group ) . Participants are eligible if they have a known disease duration of over 1 year and have used SMBG or SMUG less than 3 times in the previous year . All 3 groups will receive st and ardized diabetes care . The intervention groups will receive additional instructions on how to perform self-monitoring of glucose and how to interpret the results . Main outcome measures are changes in diabetes specific emotional distress and self-efficacy . Secondary outcome measures include difference in HbA1c , patient satisfaction , occurrence of hypoglycaemia , physical activity , costs of direct and indirect healthcare and changes in illness beliefs . Discussion The IN CONTROL-trial is design ed to explore whether feedback from self-monitoring of glucose in T2DM patients who do not require insulin can affect diabetes specific emotional distress and increase self-efficacy . Based on the self-regulation model it is hypothesized that glucose self-monitoring feedback changes illness perceptions , guiding the patient to reduce emotional responses to experienced threats , and influences the patients ability to perform and maintain self-management skills . Trial registration Current Controlled Trials IS RCT AIM Patient education that enhances one 's self-management ability is of utmost importance for improving patient outcomes in chronic diseases . We developed a 12 month self-management education program for type 2 diabetes , based on a previous 6 month program , and examined its efficacy . METHODS A r and omized controlled trial was carried out on out patients with type 2 diabetes from two hospitals who met the criteria and gave consent to participate . They were r and omly divided into an intervention group that followed the program and a control group that followed usual clinical practise . The intervention group received < 30 min of monthly interviews based on the program 's textbook and biweekly telephone calls from a nurse educator throughout the 12 months . RESULTS Of the 50 participants in the intervention group and the 25 participants in the control group , 42 and 23 , respectively , completed the program ( a completion rate of 84.0 % ) . The body weight , HbA1c , self-efficacy , dietary and exercise stages , quality of life , diastolic blood pressure , and total cholesterol level were significant by two-way repeated- measures anova . As for changes over time within the groups , only the intervention group showed significant differences by Friedman 's test . The complication prevention behaviors showed a high implementation rate in the intervention group . The overall evaluation of this program by the participants was very high and , therefore , they highly recognized the need for this type of program . CONCLUSIONS Self-management education works successfully in relation to patients ' behavior modification skills , degree of goal attainment , and self-efficacy , consequently improving their health outcomes Inadequate knowledge of the influence of lifestyle on clinical outcomes contributes to the difficulties many African Americans experience with type 2 diabetes mellitus ( T2DM ) . This pilot study examined a 12-week church-based culturally targeted diabetes self-management education ( DSME ) intervention for middle-aged and older African Americans with T2DM . Quantitative data were collected at baseline and at 12 weeks and included question naires and anthropometric measures . There were significant increases in medication adherence ( p = .006 ) , healthy eating ( p = .009 ) , and foot care adherence ( p = .003 ) . The intervention had a clinical ly significant effect on systolic blood pressure , blood lipids , physical activity , and waist circumference . Church-based culturally targeted DSME interventions may result in improved outcomes for African-American adults with T2DM . The authors discuss the value of community-based interventions that target behavioural changes in population s of chronically ill patients , particularly those who historically have been disenfranchised and /or underserved Self-management has been described as the cornerstone of care for diabetes . Many self-management studies are limited by poor methodology and poor descriptions of the intervention . The current study developed a theoretically based self-management programme for patients with type 2 diabetes , which was evaluated via a r and omized controlled trial . At immediate post-intervention and three-month follow-up the intervention group showed significant improvement relative to controls on self-management behaviours , quality of life and illness beliefs . A trend towards improved HbA1c was also observed . Documentation in a manual and development of a training programme for facilitators ensures the programme is replicable Background Self-management is crucial in the daily management of type 2 diabetes . It has been suggested that mHealth may be an important method for enhancing self-management when delivered in combination with health counseling . Objective The objective of this study was to test whether the use of a mobile phone – based self-management system used for 1 year , with or without telephone health counseling by a diabetes specialist nurse for the first 4 months , could improve glycated hemoglobin A1c ( HbA1c ) level , self-management , and health-related quality of life compared with usual care . Methods We conducted a 3-arm prospect i ve r and omized controlled trial involving 2 intervention groups and 1 control group . Eligible participants were persons with type 2 diabetes with an HbA1c level ≥7.1 % ( ≥54.1 mmol/mol ) and aged ≥18 years . Both intervention groups received the mobile phone – based self-management system Few Touch Application ( FTA ) . The FTA consisted of a blood glucose – measuring system with automatic wireless data transfer , diet manual , physical activity registration , and management of personal goals , all recorded and operated using a diabetes diary app on the mobile phone . In addition , one intervention group received health counseling based on behavior change theory and delivered by a diabetes specialist nurse for the first 4 months after r and omization . All groups received usual care by their general practitioner . The primary outcome was HbA1c level . Secondary outcomes were self-management ( heiQ ) , health-related quality of life ( SF-36 ) , depressive symptoms ( CES-D ) , and lifestyle changes ( dietary habits and physical activity ) . Data were analyzed using univariate methods ( t test , ANOVA ) and multivariate linear and logistic regression . Results A total of 151 participants were r and omized : 51 to the FTA group , 50 to the FTA-health counseling ( FTA-HC )  group , and 50 to the  control group . Follow-up data after 1 year were available for 120 participants ( 79 % ) . HbA1c level decreased in all groups , but did not differ between groups after 1 year . The mean change in the heiQ domain skills and technique acquisition was significantly greater in the FTA-HC group after adjusting for age , gender , and education ( P=.04 ) . Other secondary outcomes did not differ between groups after 1 year . In the FTA group , 39 % were substantial users of the app ; 34 % of the FTA-HC group were substantial users . Those aged ≥63 years used the app more than their younger counterparts did ( OR 2.7 ; 95 % CI 1.02 - 7.12 ; P=.045 ) . Conclusions The change in HbA1c level did not differ between groups after the 1-year intervention . Secondary outcomes did not differ between groups except for an increase in the self-management domain of skill and technique acquisition in the FTA-HC group . Older participants used the app more than the younger participants did BACKGROUND Diabetes education can improve the quality of care of people with diabetes , but many organizations are not equipped to manage its implementation . Involving people with diabetes in the education process can overcome the problem . Thus , we compared clinical , metabolic and psychological outcomes in people with type 2 diabetes 1 year after attending a structured diabetes education programme implemented by professional educators versus the same programme implemented by trained peers with diabetes  that also provided ongoing peer support . METHODS People with type 2 diabetes ( 25 - 75 years ) were r and omly assigned to attend a 4-week structured diabetes education course delivered by professional educators ( control ) or previously trained peers ( peer ) . Peers also received continuing psychological support , including examples on how to apply diabetes knowledge in daily life via weekly peer cellular phone calls and bimonthly face-to-face interviews in small groups ( ten patients ) , using a structured question naire related to the patient 's clinical , metabolic and psychological progress . Identical outcome data from both groups were used for follow-up . RESULTS Both groups had a comparable positive effect on clinical , metabolic and psychological indicators immediately following the programme . Over the following year , peer-educated subjects had lower A(1C ) and systolic blood pressure and showed higher adherence to physical activity and better control of hypoglycaemic episodes . CONCLUSION The non-inferiority of the peer outcomes and the mentioned improvements in this group suggest that volunteer trained peer educators and ongoing support can be successful . This approach provides an effective alternative method of education , especially in areas with limited availability of professionals and economic re sources
There were no differences between the groups in mortality rate , body mass index , blood pressure and lipid profile .
Conclusions Group-based DSME in people with type 2 diabetes results in improvements in clinical , lifestyle and psychosocial outcomes
Background Diabetes self-management education ( DSME ) can be delivered in many forms .
Group based DSME is widespread due to being a cheaper method and the added advantages of having patient meet and discuss with each other .
assess effects of group-based DSME compared to routine treatment on clinical , lifestyle and psychosocial outcomes in type-2 diabetes patients .
