Long-term evaluation of a structured outpatient education programme for intensified insulin therapy in patients with Type 1 diabetes: a 12-year follow-up

From educator to facilitator: Healthcare professionals' experiences of, and views about, delivering a type 1 diabetes structured education programme (DAFNEplus ) informed by behavioural science

AIMS

The DAFNEplus programme incorporates behaviour change techniques into a modified educational intervention and was developed to help address the glycaemic drift observed amongst graduates of standard DAFNE programmes. As the programme's success will be contingent on staff buy-in, we explored healthcare professionals' experiences of, and views about, delivering DAFNEplus during a clinical trial to help inform decision making about rollout post-trial.

METHODS

We interviewed n = 18 nurses and dieticians who delivered DAFNEplus during the trial. Data were analysed thematically.

RESULTS

While many shared initial reservations, all described how their experiences of DAFNEplus programme delivery had had a positive, transformative impact upon their perceptions and working practices. This transformation was enabled by initial training and supervision sessions, the confidence gained from using scripts to support novel programme content delivery, and experiences of delivering the programme and observing DAFNEplus principles being well received by, and having a positive impact on, attendees. Due to these positive experiences, interviewees described a strongly felt ethical mandate to use some DAFNEplus techniques and curriculum content in routine clinical care. While being supportive of a national rollout, they anticipated a variety of attitudinal and logistical (e.g. workload) challenges.

CONCLUSIONS

This study provides a vital dimension to the evaluation of the DAFNEplus programme. Interviewees found the intervention to be acceptable and expressed high levels of buy-in. As well as offering potential endorsement for a national rollout, our findings offer insights which could help inform development and rollout of future behaviour change interventions to support diabetes self-management.

Sustaining the benefits of structured education: Participants' experiences of receiving structured individual support during a programme (DAFNEplus) informed by behavioural science

AIMS

The DAFNEplus programme seeks to promote sustained improvements in glycaemic management by incorporating techniques from behavioural science. It includes five sessions of structured individual support delivered over 12 months following group education. As part of a broader evaluation, and to inform decision-making about roll-out in routine care, we explored participants' experiences of, and engagement with, that individual support.

METHODS

We interviewed DAFNEplus participants (n = 28) about their experiences of receiving individual support and the impact they perceived it as having on their self management practices. We analysed data thematically.

RESULTS

Participants described several important ways individual support had helped strengthen their self management, including: consolidating and expanding their understandings of flexible intensive insulin therapy; promoting ongoing review and refinement of behaviour; encouraging continued and effective use of data; and facilitating access to help from healthcare professionals to pre-empt or resolve emergent difficulties. Participants characterised themselves as moving towards independence in self management over the time they received individual support, with their accounts suggesting three key stages in that journey: 'Working with healthcare professionals'; 'Growing sense of responsibility'; and, 'Taking control'. Whilst all portrayed themselves as changed, participants' progress through those stages varied; a few continued to depend heavily on DAFNEplus facilitators for advice and/or direction at 12 months.

CONCLUSIONS

While all participants benefited from individual support, our findings suggest that some may need, or gain further benefit from, longer-term, tailored support. This has important implications for decision-making about roll-out of DAFNEplus post-trial and for the development of future programmes seeking to bring about sustainable changes in self management practices.

Simplified integration of optimal self-management behaviors is associated with improved HbA1c in patients with type 1 diabetes

PURPOSE

Living with type 1 diabetes requires burdensome and complex daily diabetes self-management behaviors. This study aimed to determine the association between integrated behavior performance and HbA1c, while identifying the behavior with the most significant impact on HbA1c.

METHODS

A simple and feasible questionnaire was used to collect diabetes self-management behavior in patients with type 1 diabetes (n = 904). We assessed six dimensions of behavior performance: continuous glucose monitor (CGM) usage, frequent glucose testing, insulin pump usage, carbohydrate counting application, adjustment of insulin doses, and usage of apps for diabetes management. We evaluated the association between these behaviors and HbA1c.

RESULTS

In total, 21.3% of patients performed none of the allotted behavior, while 28.5% of patients had a total behavior score of 3 or more. 63.6% of patients with a behavior score ≥ 3 achieved HbA1c goal, contrasting with only 30.4% of patients with a behavior score of 0-1. There was a mean 0.54% ± 0.05% decrease in HbA1c for each 1-unit increase in total behavior score after adjustment for age, family education and diabetes duration. Each behavior was independently correlated with a lower HbA1c level, with CGM having the most significant effect on HbA1c levels.

CONCLUSIONS

Six optimal self-management behaviors, especially CGM usage, were associated with improved glycemic control, emphasizing the feasibility of implementing a simplified version of DSMES in the routine clinical care.

Participants' experiences of attending a structured education course (DAFNEplus) informed by behavioural science

AIMS

As part of a broader process evaluation, we explored participants' experiences of, and engagement with, the DAFNEplus programme's group-based structured education course. This course, which was informed by behavioural science, provided participants with education and instruction to use flexible intensive insulin therapy (FIIT) together with techniques to identify and address unhelpful cognitive and emotional influences on their type 1 diabetes self-management.

METHODS

We interviewed n = 28 DAFNEplus participants. Data were analysed thematically and took account of previous work exploring individuals' experiences of standard DAFNE courses.

RESULTS

As well as benefitting from the DAFNEplus course's skills-based training and educational curriculum, participants' accounts suggested they had experienced cognitive and emotional changes that had positively influenced their confidence and motivation to adopt and sustain the use of FIIT. These benefits were most keenly felt by those who reported negative emotional states and mind-sets pre-course which had made their diabetes self-management challenging. Participants' cognitive and emotional changes were enabled through techniques used during the course to normalise setbacks and imperfect diabetes self-management, capitalise upon group synergies and encourage the use of social support, including from healthcare professionals. Participants also highlighted motivational gains arising from being reassured that diabetes complications are not common or inevitable if a FIIT regimen is followed.

CONCLUSIONS

Our findings suggest that offering training in FIIT, in conjunction with behaviour change techniques that target unhelpful mindsets and emotional resilience, may be more effective in promoting diabetes self-management than offering education and skills training alone.

Epidemiological parameters and monitoring of analysis of treatment of children and adolescents with type 1 diabetes mellitus in insulin pump therapy with modified educational program

OBJECTIVE

Aim: The aim of the present published work is efficacy evaluation of the modified educational program in achieving the target levels of glycemia in children and adolescents with type 1 diabetes mellitus in pump insulin therapy in Almaty..

PATIENTS AND METHODS

Materials and Methods: This study involved 125 children and adolescents with type 1 DM and evaluated the effectiveness of a modified educational program at the School of Type 1 Diabetes Mellitus. Participants were divided into subgroups based on their method of glycemia evaluation. The program's effectiveness was assessed through pre-and post-training questionnaires and measurement of glycohemoglobin levels. Statistical analysis was conducted using the Statistica application.

RESULTS

Results: The study evaluated the effectiveness of a modified educational program for children and adolescents with type 1 DM. The results indicated that those who participated in the modified program demonstrated significant improvements in their knowledge and ability to manage their diabetes. They were able to correctly answer 80-90% of the questionnaire questions six months to a year after the training. Additionally, those in the modified program exhibited better carbohydrate metabolism rates and achieved higher rates of their individual treatment goals, especially when using the FreeStyle Libre system for continuous monitoring of blood glucose levels. These findings suggest that a modified educational approach can significantly enhance diabetes management and treatment outcomes in children and adolescents.

CONCLUSION

Conclusions: The study concluded that a modified educational program leads to better target therapy levels in children and adolescents with type 1 diabetes mellitus, highlighting the importance of motivated parents and frequent blood glycemia measurements.

Current and future therapies to treat impaired awareness of hypoglycemia

In order to achieve optimal glycemic control, intensive insulin regimes are needed for individuals with Type 1 Diabetes (T1D) and insulin-dependent Type 2 Diabetes (T2D). Unfortunately, intensive glycemic control often results in insulin-induced hypoglycemia. Moreover, recurrent episodes of hypoglycemia result in both the loss of the characteristic warning symptoms associated with hypoglycemia and an attenuated counterregulatory hormone responses. The blunting of warning symptoms is known as impaired awareness of hypoglycemia (IAH). Together, IAH and the loss of the hormonal response is termed hypoglycemia associated autonomic failure (HAAF). IAH is prevalent in up to 25% in people with T1D and up to 10% in people with T2D. IAH and HAAF increase the risk of severe hypoglycemia 6-fold and 25-fold, respectively. To reduce this risk for severe hypoglycemia, multiple different therapeutic approaches are being explored that could improve awareness of hypoglycemia. Current therapies to improve awareness of hypoglycemia include patient education and psychoeducation, the use of novel glycemic control technology, pancreas/islet transplantation, and drug therapy. This review examines both existing therapies and potential therapies that are in pre-clinical testing. Novel treatments that improve awareness of hypoglycemia, via improving the counterregulatory hormone responses or improving hypoglycemic symptom recognition, would also shed light on the possible neurological mechanisms that lead to the development of IAH. To reduce the risk of severe hypoglycemia in people with diabetes, elucidating the mechanism behind IAH, as well as developing targeted therapies is currently an unmet need for those that suffer from IAH.

A Systematic Review Supporting the Endocrine Society Guidelines: Management of Diabetes and High Risk of Hypoglycemia

CONTEXT

Interventions targeting hypoglycemia in people with diabetes are important for improving quality of life and reducing morbidity and mortality.

OBJECTIVE

To support development of the Endocrine Society Clinical Practice Guideline for management of individuals with diabetes at high risk for hypoglycemia.

METHODS

We searched several databases for studies addressing 10 questions provided by a guideline panel from the Endocrine Society. Meta-analysis was conducted when feasible. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology was used to assess certainty of evidence.

RESULTS

We included 149 studies reporting on 43 344 patients. Continuous glucose monitoring (CGM) reduced episodes of severe hypoglycemia in patients with type 1 diabetes (T1D) and reduced the proportion of patients with hypoglycemia (blood glucose [BG] levels <54 mg/dL). There were no data on use of real-time CGM with algorithm-driven insulin pumps vs multiple daily injections with BG testing in people with T1D. CGM in outpatients with type 2 diabetes taking insulin and/or sulfonylureas reduced time spent with BG levels under 70 mg/dL. Initiation of CGM in hospitalized patients at high risk for hypoglycemia reduced episodes of hypoglycemia with BG levels lower than 54 mg/dL and time spent under 54 mg/dL. The proportion of patients with hypoglycemia with BG levels lower than 70 mg/dL and lower than 54 mg/dL detected by CGM was significantly higher than point-of-care BG testing. We found no data evaluating continuation of personal CGM in the hospital. Use of an inpatient computerized glycemic management program utilizing electronic health record data was associated with fewer patients with and episodes of hypoglycemia with BG levels lower than 70 mg/dL and fewer patients with severe hypoglycemia compared with standard care. Long-acting basal insulin analogs were associated with less hypoglycemia. Rapid-acting insulin analogs were associated with reduced severe hypoglycemia, though there were more patients with mild to moderate hypoglycemia. Structured diabetes education programs reduced episodes of severe hypoglycemia and time below 54 mg/dL in outpatients taking insulin. Glucagon formulations not requiring reconstitution were associated with longer times to recovery from hypoglycemia, although the proportion of patients who recovered completely from hypoglycemia was not different between the 2 groups.

CONCLUSION

This systematic review summarized the best available evidence about several interventions addressing hypoglycemia in people with diabetes. This evidence base will facilitate development of clinical practice guidelines by the Endocrine Society.

Flexible insulin therapy improves metabolic control and decreases the risk of hypoglycemia in type 1 diabetic patients

Introduction

flexible insulin therapy (FIT) is considered as a crucial turning point in the management of type 1 diabetes. The purpose of this study was to evaluate the impact of this optimum therapeutic approach on improving metabolic control and decreasing hypoglycemic events in patients with type 1 diabetes.

Methods

thirty-seven type 1 diabetic patients were included in a five days training programme of FIT. They had an HbA1c between 7.5 and 10%. Those patients were enrolled in a flexible insulin program and we evaluate clinical and metabolic parameters (glycated haemoglobin (HbA1c), hypoglycemic events, body mass index (BMI) and the rate of blood glucose measurements) before the course of FIT and 3, 6 and 9 months after the course.

Results

over a 9 months period of the study, the frequency of mild hypoglycemia decreased from 11.7 to 1.7 episodes/3 months (p = 0.005). The baseline HbA1c value improved by 1% at 3 months with an increase of 0.2% at 6 months, which remained unchanged at 9 months (p = <0.0001). Patients who were poorly controlled (HbA1c ≥ 8%) improved their baseline HbA1c value from 9.2% to 8.0% (p = <0.0001).

Conclusion

the present study confirms that a structured training programme for FIT improves glycemic control and decreases hypoglycemic events in patients with type 1 diabetes and it can be adopted in countries with weak or intermediate income (e.g. Morocco), which allows those patients to take advantages of this therapeutic approach.

Clinical approaches to treat impaired awareness of hypoglycaemia

Impaired awareness of hypoglycaemia (IAH) affects between 25% and 30% of all people with type 1 diabetes (T1D) and markedly increases risk of severe hypoglycaemia. This greatly feared complication of T1D impairs quality of life and has a recognised morbidity. People with T1D have an increased propensity to hypoglycaemia as a result of fundamental physiological defects in their ability to respond appropriately to a fall in blood glucose levels. With repeated exposure to low glucose, many then develop a condition referred to as IAH, where there is a reduced ability to perceive the onset of hypoglycaemia and take appropriate corrective action. The management of individuals with IAH relies initially on its identification in the clinic through a detailed exploration of the frequency of hypoglycaemia and an assessment of the individual's ability to recognise these episodes. In this review article, we will address the clinical strategies that may help in the management of the patient with IAH once identified, who may or may not also suffer from problematic hypoglycaemia. The initial focus is on how to identify such patients and then on the variety of approaches involving educational programmes and technological approaches that may be taken to minimise hypoglycaemia risk. No single approach can be advocated for all patients, and it is the role of the health care professional to identify the clinical strategy that best enables their patient to achieve this goal.

An automated structured education intervention based on a smartphone app in Chinese patients with type 1 diabetes: a protocol for a single-blinded randomized controlled trial

BACKGROUND

Although evidence had demonstrated the effectiveness of smartphone apps in diabetes care, the majority of apps had been developed for type 2 diabetes mellitus (T2DM) patients and targeted at populations outside of China. The effects of applying a smartphone app with structured education on glycemic control in type 1 diabetes mellitus (T1DM) are unclear. A digital, culturally tailored structured education program was developed in a smartphone app (Yi tang yun qiao) to provide an automated, individualized education program aimed at improving self-management skills in patients with T1DM in China. This trial aims to investigate the effectiveness of this smartphone app among Chinese T1DM patients.

METHODS AND ANALYSIS

This single-blinded, 24-week, parallel-group randomized controlled trial of a smartphone app versus routine care will be conducted in Changsha, China. We plan to recruit 138 patients with T1DM who will be randomly allocated into the intervention group (automated, individualized education through an app) or routine care group. The intervention will last for 24 weeks. The primary outcome will be the change in glycated hemoglobin (HbA1c) from baseline to week 24. The secondary outcomes will include time in range, fasting blood glucose, levels of serum triglycerides and cholesterol, blood pressure, body mass index, quality of life, diabetes self-care activities, diabetes self-efficacy, depression, anxiety, and patient satisfaction. Adverse events will be formally documented. Data analysis will be conducted using the intention-to-treat principle with appropriate univariate and multivariate methods. Missing data will be imputed with a multiple imputation method under the "missing at random" assumption.

DISCUSSION

This trial will investigate the effectiveness of an app-based automated structured education intervention for Chinese patients with T1DM. If the intervention is effective, this study will provide a strategy that satisfies the need for effective lifelong diabetes care to reduce the disease burden and related complications resulting from T1DM.

E-health education interventions on HbA1c in patients with type 1 diabetes on intensive insulin therapy: A systematic review and meta-analysis of randomized controlled trials

AIMS

Patient-centered education improves glycemic control in subjects with type 1 diabetes (T1D). E-health technologies are widely used to support medical decision-making, patient advising or teleconsultations; however, the active participation of a patient is missing. Challenges remain whether e-health education can be effectively incorporated into clinical pathways. The purpose of the study was to examine the effects of e-health education, compared to standard care, on HbA_1c. MATERIAL AND METHODS: We conducted a literature search (EMBASE, MEDLINE, The Cochrane Library and Web of Science) up to February 2018 for randomized controlled trials (RCTs) of Internet-/ mobile application-based educational interventions, with the active involvement of patients, provided in addition to, or substituting usual care in patients with T1D on intensive insulin therapy. The primary outcome was the standardized difference in means (SDM) of HbA_1c change from baseline between intervention and comparator groups.

RESULTS

Eight RCTs involving 757 subjects were included on 6335 screened citations. After excluding two trials with a high risk of bias from the meta-analysis, the HbA_1c change from baseline did not significantly differ between intervention and comparator groups (SDM = -0.154, 95% CI: -0.335 to 0.025; P = 0.01, random-effect model). The number of studies is limited with a relatively short duration. Reporting of educational outcomes was not rigorous.

CONCLUSIONS

The effect of e-health educational interventions on HbA_1c in patients with T1D is comparable to the standard care. This review highlights the need for further well-designed RCTs that will investigate the opportunities of incorporating e-health education into clinical pathways.

Establishment of a type 1 diabetes structured education programme suitable for Chinese patients: type 1 diabetes education in lifestyle and self adjustment (TELSA)

BACKGROUND

Various guidelines recommend that all adults diagnosed with type 1 diabetes (T1D) should be offered an evidence based, structured education programme (SEP) to optimize self-management care. China has a 13,000 annual increase in newly diagnosed T1D cases, of which 65% are adults. However, there is yet no validated SEP targeted to T1D patients in China. The purpose of this study is to establish a structured T1D self-management education programme-'Type 1 Diabetes Education in Lifestyle and Self Adjustment' (TELSA) that is adapted to medical and cultural practices in China.

METHODS

TELSA programme was developed based on the ADDIE model, following three steps: i) Semi-structured interviews were administered to 10 healthcare professionals (HCPs) and 13 T1D patients. Different topic guides, focusing on 4 dimensions including goals, contents, format of delivery, and quality assurance, were designed for either HCPs or patients. The interviews were recorded and analysed with thematic analysis. ii) Extracted themes were modified according to Delphi consultation. iii) Preliminary courses were conducted as pilot study to evaluate the effects of TELSA and optimization of the curriculum was finalized accordingly.

RESULTS

A total of 18 themes in 4 dimensions of the programme design were identified in the final version: i) goals: 'behaviour modification' and 'outcome improvement'; ii) contents: 'living with T1D', 'self-monitoring of blood glucose', 'knowing insulin', 'insulin dose adjustment', 'carbohydrates and carbohydrate counting', 'hypoglycaemia', 'complications of diabetes', 'managing psychological issues', 'physical activity', and 'question-and-answer'; iii) format: 'multidisciplinary team combined with peer support', 'face-to-face education followed by remote learning', and '2-day programme held on weekends'; and iv) quality assurance: 'after-class quiz', 'patients' feedback', and 'long-term evaluation on effectiveness'.

CONCLUSIONS

A type 1 diabetes structured education programme in China was set up and shown to be applicable under local medical, social, and cultural environment.

Different Effects of Structured Education on Glycemic Control and Psychological Outcomes in Adolescent and Adult Patients with Type 1 Diabetes: A Systematic Review and Meta-Analysis

AIM

This systematic review aimed at investigating the effectiveness of structured education (SE) in improving glycemic control and psychological outcomes in adolescent and adult patients with type 1 diabetes.

METHODS

Electronic databases (EMBASE, Medline, PubMed, and the Cochrane Library) and the reference lists of included studies were searched from the beginning of the database through April 2019. Randomized controlled trials comparing SE with a control condition and reporting a change in glycosylated hemoglobin (HbA1c) level were included. The primary outcome was glycemic control measured by HbA1c. Secondary outcomes were diabetes-related distress, well-being, depression, and quality of life.

RESULTS

Eighteen studies representing 2759 patients were included. Twelve studies targeted adolescents and six targeted adults. Adolescent patients who were randomized to the intervention group did not show significant improvement of HbA1c in the short (SMD = -0.04; 95% CI: -0.14 to 0.06; P=0.41), medium (SMD = -0.03; 95% CI: -0.13 to 0.07; P=0.41), medium (SMD = -0.03; 95% CI: -0.13 to 0.07; P=0.41), medium (SMD = -0.03; 95% CI: -0.13 to 0.07; P=0.41), medium (SMD = -0.03; 95% CI: -0.13 to 0.07; P=0.41), medium (SMD = -0.03; 95% CI: -0.13 to 0.07.

CONCLUSIONS

Development of more efficient SE programs according to the patients' personal characteristics is needed.

Comparison of the efficacy of an education program for people with diabetes and insulin pump treatment (INPUT) in a randomized controlled trial setting and the effectiveness in a routine care setting: Results of a comparative effectiveness study

OBJECTIVE

To compare the efficacy of an education program for people with diabetes and insulin pump treatment (INPUT) in a randomized controlled trial (RCT) to the effectiveness in an implementation trial (IT).

METHODS

135 people with diabetes on insulin pump treatment (CSII) underwent structured education with INPUT under RCT-conditions, 191 people with diabetes on CSII underwent structured education with INPUT under IT-conditions. Baseline characteristics and treatment outcomes at the 6-month follow-up were compared.

RESULTS

At baseline, RCT-participants were younger (42.7 ± 14.2 vs. 47.2 ± 14.1 years, p = 0.005), had higher HbA1c-values (8.3 ± 0.8% vs. 7.8 ± 1.2%, p = 0.001) and had more diabetes-related distress (27.8 ± 16.4 vs 22.4 ± 14.4, p = 0.002). At follow-up, INPUT results were comparable under the RCT and IT settings. After adjustment for baseline HbA1c, reduction of HbA1c in the IT was significantly greater than in the RCT (Δ0.17%; 95% CI 0.023-0.319%, p = 0.024). Participants with higher HbA1c-levels, more diabetes-related distress and more hypoglycemia problems were most likely to benefit from INPUT regardless of the trial setting.

CONCLUSIONS

Efficacy of the INPUT program for people with CSII was demonstrated under RCT- and routine care conditions.

PRACTICE IMPLICATIONS

Education with the INPUT program is effective not only under standardized RCT conditions but also under conditions of routine care.

Assessment of Alimentación Normal con Ajuste de Insulina (ANAIS), a Spanish version of the DAFNE programme, in people with Type 1 diabetes: a randomized controlled parallel trial

AIM

To evaluate the effects of Alimentación Normal con Ajuste de Insulina (ANAIS), a group-based, therapeutic education programme for Type 1 diabetes based on a flexible insulin regimen adjusted to the individual's food intake.

METHODS

Participants with Type 1 diabetes and HbA_1c levels of 53-86 mmol/mol (7-10%) were recruited from outpatient clinics at a tertiary care centre. They were randomized (using opaque, sealed envelopes, with a 2:1 treatment allocation ratio) to attend the training course immediately (immediate ANAIS; intervention group) or a year later (delayed ANAIS; control group). The main outcome was HbA_1c level at 1 year. Secondary outcomes included lipid levels, weight, hypoglycaemic events, insulin dose, treatment satisfaction, self-perceived dietary freedom, quality of life and participant-defined goals.

RESULTS

A total of 48 participants were assigned to the intervention group and 32 to the control group. Twelve months after completing the training, adjusted HbA_1c was not significantly different in the intervention group [64 ± 1.3 vs 68 ± 1.6 mmol/mol (8.0 ±0.1% vs 8.4 ±0.1%); P=0.081]. Treatment satisfaction was significantly higher in the intervention group, but no differences were found in hypoglycaemic events, weight, insulin dose or changes in dietary freedom. At 1 year after the intervention, 72% of the participants (vs 33% in the control group; P=0.046) reported exceeding their expectations regarding achievement of their main personal goal.

CONCLUSION

Promoting dietary freedom and empowering people with Type 1 diabetes through structured education programmes, such as ANAIS, improves treatment satisfaction and self-defined goals. No significant improvement in HbA_1c level was achieved.

HCV compliance and treatment success rates are higher with DAAs in structured HCV clinics compared to general hepatology clinics

The real-world cure rates for hepatitis C (HCV) with direct-acting antivirals (DAAs) based on intention-to-treat (ITT) analysis may be lower than reported in the literature because of non-compliance.To determine whether patients treated in a structured outpatient HCV clinic (SHC) had higher compliance and treatment success rates compared to those treated in general hepatology clinics (GHC).In this study, we compared the treatment and compliance success rates of 488 and 840 patients treated in the SHC and GHC, respectively. The SHC required a pre-treatment clinic visit when patients picked up their initial medication, and received detailed education of the treatment plan and follow-up. In the GHC, the medications were delivered to patients' homes, and there was less formal education. Compliance success was defined as a combination of treatment completion and obtaining at least 1 post-treatment viral load at week 4 or 12. Treatment success was defined as either SVR4 or SVR12.Fifty of 488 (10.3%) patients from the SHC and 163 of 840 (19.4%) patients from the GHC were lost to follow-up (P < .0001). sustained virological response (SVR) rates were similar in compliant patients in both the SHC (419/438, 95.6%) and GHC (642/677, 94.8%), but treatment success rates by intention to treat (ITT) (overall 79.9%) were higher in SHC compared to GHC (85.9% vs 76.4%, P < .0001). Multivariate analysis showed that female patients (P = .01), older age (P = .0005), treatment in SHC (OR 1.7, 95% CI 1.2, 2.3, P = .0008), and sofosbuvir/simeprevir compared to sofosbuvir/ledipasvir had higher odds of compliance success; elbasvir/grazoprevir or dasabuvir/ombitasvir/paritaprevir/ritonavir had lower odds of compliance success compared to sofosbuvir/ledipasvir. Female patients (P = .02), older age (P < .0001), previous treatment (P = .03), treatment in SHC (OR 1.7, 95% CI 1.2, 2.3, P = .0008), and sofosbuvir/ledipasvir compared to sofosbuvir/velpatasvir, sofosbuvir, or elbasvir/grazoprevir had higher odds of treatment success. With 1:1 matching, the SHC group still had significantly higher odds than the GHC group of achieving treatment and compliance success.Our study shows that the effectiveness of HCV treatment could be improved by coordinating treatment in a structured HCV clinic.

Suboptimal behaviour and knowledge regarding overnight glycaemia in adults with type 1 diabetes is common

BACKGROUND

In people with type 1 diabetes (T1D), nocturnal hypoglycaemia (NH) can be slept through and can cause seizures, arrhythmias and death. Hypoglycaemia avoidance can induce hyperglycaemia and ketosis. Patient behaviour impacts clinical outcomes and may be changed by education.

AIM

To develop and utilise a survey to evaluate patient self-management of overnight glycaemia in adults with T1D.

METHODS

Adults with T1D attending two Australian tertiary referral diabetes clinics completed a survey about their diabetes self-management and glycaemic control, including responses to hypothetical pre-bed blood glucose (BG) levels (4-20 mmol/L). Statistical analyses included t-tests, Chi square tests and ANOVA with significance considered at P < 0.05.

RESULTS

There were 205 participants (103 females), with a mean (SD) age of 41 (17) years, T1D duration of 20 (16) years, HbA1c of 7.8(1.4)%, (61.3(8.2) mmol/mol), 38% on insulin pump therapy (CSII) and 36% with impaired hypoglycaemia awareness (IHA). Mean (SD) number of BG tests/day was 5.4 (2.7). Patients set higher BG target levels at bedtime and overnight: 7.5(1.4) and 7.1(1.3) mmol/L, respectively, compared to daytime (6.9(1.0); P < 0.0001 and P = 0.002 respectively). Only 36% of participants reported treating nocturnal hypoglycaemia (NH) with the recommended refined, then complex, carbohydrate. Only 28% of patients made safe choices in all bedtime BG scenarios, with higher rates for CSII users, P = 0.0005. Further education was desired by 32% of respondents, with higher rates in those with (44%) versus without IHA (25%), P = 0.006.

CONCLUSIONS

Many adults with T1D have suboptimal knowledge and behaviour regarding overnight BG self-management. A survey, piloted herein, may facilitate the identification of patients who could benefit from further education.

Impact of diabetes education and self-management on the quality of care for people with type 1 diabetes mellitus in the Middle East (the International Diabetes Mellitus Practices Study, IDMPS)

AIMS

Self-management (self-monitoring of blood glucose, plus self-adjustment of insulin dose) is important in diabetes care, but its complexity presents a barrier to wider implementation, which hinders attainment and maintenance of glycemic targets. More evidence on self-management is needed to increase its implementation and improve metabolic outcomes.

METHODS

Data from 1316 participants with type 1 diabetes mellitus who were enrolled from Middle East countries into the International Diabetes Management Practices Study (IDMPS), a multinational observational survey, were analyzed to assess the impact of education on disease management and outcomes.

RESULTS

A majority (78%) of participants failed to achieve glycemic target (HbA_1c < 7.0% [<53 mmol/mol]). Participants who had received diabetes education (59%) were more likely to practice self-management than those who had not (odds ratio [OR]: 2.51; 95% confidence interval [CI]: 1.7-3.69; p < 0.001), and those who practiced self-management were more likely to attain target HbA_1c than those who did not (OR: 1.49; 95% CI: 1.06-2.09; p = 0.023).

CONCLUSIONS

These relationships between diabetes education, self-management and glycemic control suggest that diabetes education provides knowledge and skills to optimize self-management, favoring HbA_1c target attainment. Middle East health authorities should search for ways to facilitate access to diabetes education to optimize treatment outcomes.

Follow-Up Support for Effective type 1 Diabetes self-management (The FUSED Model): A systematic review and meta-ethnography of the barriers, facilitators and recommendations for sustaining self-management skills after attending a structured education programme

Background

People with type 1 diabetes who attend structured education training in self-management using flexible intensive therapy achieve improved blood glucose control and experience fewer episodes of severe hypoglycaemia. However, many struggle to sustain these improvements over time. To inform the design of more effective follow-up support we undertook a review of qualitative studies which have identified factors that influence and inform participants’ self-management behaviours after attending structured education and their need for support to sustain improvements in glycaemic control.

Methods

We undertook a meta-ethnography of relevant qualitative studies, identified using systematic search methods. Studies were included which focused on participants’ experiences of self-managing type 1 diabetes after attending structured education which incorporated training in flexible intensive insulin therapy. A line of argument approach was used to synthesise the findings.

Results

The search identified 18 papers from six studies. The studies included were judged to be of high methodological quality. The line of argument synthesis developed the Follow-Up Support for Effective type 1 Diabetes self-management (FUSED) model. This model outlines the challenges participants encounter in maintaining diabetes self-management practices after attending structured education, and describes how participants try to address these barriers by adapting, simplifying or personalising the self-management approaches they have learned. To help participants maintain the skills taught during courses, the FUSED model presents ten recommendations abstracted from the included papers to provide a logic model for a programme of individualised and responsive follow-up support.

Conclusions

This meta-ethnography highlights how providing skills training using structured education to people with type 1 diabetes does not necessarily result in participants adopting and sustaining recommended changes in behaviour. To help people sustain diabetes self-management skills after attending structured education, it is recommended that support be provided over the longer-term by appropriately trained healthcare professionals which is responsive to individuals’ needs. Although developed to inform support for people with type 1 diabetes, the FUSED model provides a framework that could also be applied to support individuals with other long term conditions which require complex self-management skills to be learned and sustained over time.

The role of structured education in the management of hypoglycaemia

The role of intensive glycaemic control in preventing microvascular disease in diabetes is well established. Iatrogenic hypoglycaemia is, however, a major barrier to effective treatment. Hypoglycaemia is associated with a significant level of morbidity and, despite pharmacological and technological therapeutic advances, reported rates of severe hypoglycaemia in clinical practice have not fallen over the last 20 years. This suggests that human factors are of major relevance and that ensuring the effective self-management of diabetes is an important strategy for the reduction of hypoglycaemic risk. Most of the evidence for the impact of this strategy on hypoglycaemia risk is confined to adults with type 1 diabetes although, in this review, we also cite studies that have specifically addressed this in type 2 diabetes. There are relatively few adequately powered RCTs that have rigorously evaluated the effectiveness of structured education and training programmes on hypoglycaemia; however, the available data suggest a subsequent reduction in severe hypoglycaemia rates of around 50%, a rate reduction that is comparable with that observed following technological interventions. Furthermore, longitudinal observational cohorts support these data, showing similar reductions in rates of hypoglycaemia following structured education. Those who continue to experience recurrent hypoglycaemia and impaired awareness of hypoglycaemia despite education and training in diabetes self-management may benefit from technological interventions and/or interventions that specifically address psychological factors that contribute to hypoglycaemia risk; however, there is urgent need for further research in this area. In the meantime, structured education for effective self-management of diabetes should be part of routine therapy for all those with type 1 diabetes.

Diabetes structured self-management education programmes: a narrative review and current innovations

Both type 1 and type 2 diabetes are associated with long-term complications that can be prevented or delayed by intensive glycaemic management. People who are empowered and skilled to self-manage their diabetes have improved health outcomes. Over the past 20 years, diabetes self-management education programmes have been shown to be efficacious and cost-effective in promotion and facilitation of self-management, with improvements in patients' knowledge, skills, and motivation leading to improved biomedical, behavioural, and psychosocial outcomes. Diabetes self-management education programmes, developed robustly with an evidence-based structured curriculum, vary in their method of delivery, content, and use of technology, person-centred philosophy, and specific aims. They are delivered by trained educators, and monitored for quality by independent assessors and routine audit. Self-management education should be tailored to specific populations, taking into consideration the type of diabetes, and ethnic, social, cognitive, literacy, and cultural factors. Ways to improve access to and uptake of diabetes self-management programmes are needed globally.

Carbohydrate Counting in Children and Adolescents with Type 1 Diabetes

Carbohydrate counting (CC) is a meal-planning tool for patients with type 1 diabetes (T1D) treated with a basal bolus insulin regimen by means of multiple daily injections or continuous subcutaneous insulin infusion. It is based on an awareness of foods that contain carbohydrates and their effect on blood glucose. The bolus insulin dose needed is obtained from the total amount of carbohydrates consumed at each meal and the insulin-to-carbohydrate ratio. Evidence suggests that CC may have positive effects on metabolic control and on reducing glycosylated haemoglobin concentration (HbA1c). Moreover, CC might reduce the frequency of hypoglycaemia. In addition, with CC the flexibility of meals and snacks allows children and teenagers to manage their T1D more effectively within their own lifestyles. CC and the bolus calculator can have possible beneficial effects in improving post-meal glucose, with a higher percentage of values within the target. Moreover, CC might be integrated with the counting of fat and protein to more accurately calculate the insulin bolus. In conclusion, in children and adolescents with T1D, CC may have a positive effect on metabolic control, might reduce hypoglycaemia events, improves quality of life, and seems to do so without influencing body mass index; however, more high-quality clinical trials are needed to confirm this positive impact.

Accurate Carbohydrate Counting Is an Important Determinant of Postprandial Glycemia in Children and Adolescents With Type 1 Diabetes on Insulin Pump Therapy

BACKGROUND

Carbohydrate (CHO) counting is a key nutritional intervention utilized in the management of diabetes to optimize postprandial glycemia. The aim of the study was to examine the impact of accuracy of CHO counting on the postprandial glucose in children and adolescents with type 1 diabetes on insulin pump therapy.

METHODS

Children/adolescents with type 1 diabetes who were on insulin pump therapy for a minimum of 6 months are enrolled in the study. Patients were instructed to record details of meals consumed, estimated CHO count per meal, and 2-hour postprandial glucose readings over 3-5 days. Meals' CHO contents were recounted by an experienced clinical dietician, and those within 20% of the dietician's counting were considered accurate.

RESULTS

A total of 30 patients (21 females) were enrolled. Age range (median) was 8-18 (SD 13) years. Data of 247 meals were analyzed. A total of 165 (67%) meals' CHO contents were accurately counted. Of those, 90 meals (55%) had in-target postprandial glucose ( P < .000). There was an inverse relationship between inaccurate CHO estimates and postprandial glucose. Of the 63 underestimated meals, 55 had above-target glucose, while 12 of the 19 overestimated meals were followed by low glucose. There was no association between accuracy and meal size (Spearman's rho = .019).

CONCLUSION

Accuracy of CHO counting is an important determining factor of postprandial glycemia. However, other factors should be considered when advising on prandial insulin calculation. Underestimation and overestimation of CHO result in postprandial hyperglycemia and hypoglycemia, respectively. Accuracy does not correlate with meal size.

Association of cardiac autonomic modulation with physical and clinical features of young people with type 1 diabetes

OBJECTIVE

The objective of this study was to verify possible associations between heart rate variability indices and physical activity, body composition, and metabolic and cardiovascular parameters in individuals with type 1 diabetes.

METHOD

A total of 39 young patients with type 1 diabetes were included. Body composition, physical activity, cardiovascular parameters, and metabolic parameters were assessed. For the heart rate variability analysis, heart rate was recorded beat-by-beat using a Polar S810i heart rate monitor for 30 minutes, with the volunteers in the supine position; subsequently, the following indices were considered: standard deviation of all normal RR intervals; root-mean square of differences between adjacent normal RR intervals in a time interval; percentage of adjacent RR intervals with a difference of duration >50 ms; high frequency component in milliseconds squared; high frequency component in normalised units; standard deviation of the instantaneous variability beat-to-beat; and standard deviation of the long-term variability. The association between the heart rate variability indices and independent variables was verified through linear regression in unadjusted and adjusted models (considering gender and age). The statistical significance was set at 5% and the confidence interval at 95%.

RESULTS

High values of at-rest heart rate were associated with reduced parasympathetic activity and global heart rate variability, and higher values of waist-to-hip ratio were related to lower parasympathetic activity, independent of age or gender.

CONCLUSION

For young patients with type 1 diabetes, increases in at-rest heart rate values are associated with reduced parasympathetic activity and global heart rate variability, whereas higher waist-to-hip ratio values are related to lower parasympathetic activity, both independent of age and gender.

Structured type 1 diabetes education delivered in routine care in Australia reduces diabetes-related emergencies and severe diabetes-related distress: The OzDAFNE program

AIMS

To evaluate structured type 1 diabetes education delivered in routine practice throughout Australia.

METHODS

Participants attended a five-day training program in insulin dose adjustment and carbohydrate counting between April 2007 and February 2012. Using an uncontrolled before-and-after study design, we investigated: HbA1c (% and mmol/mol); severe hypoglycaemia; diabetes ketoacidosis (DKA) requiring hospitalisation, and diabetes-related distress (Problem Areas in Diabetes scale; PAID), weight (kg); body mass index. Data were collected pre-training and 6-18 months post-training. Change in outcome scores were examined overall as well as between groups stratified by baseline HbA1c quartiles. Data are mean ± SD or % (n).

RESULTS

506 participants had data eligible for analysis. From baseline to follow-up, significant reductions were observed in the proportion of participants reporting at least one severe hypoglycaemic event (24.7% (n=123) vs 12.1% (n=59), p<0.001); and severe diabetes-related distress (29.3% (n=145) vs 12.6% (n=60), p<0.001). DKA requiring hospitalisation in the past year reduced from 4.1% (n=20) to 1.2% (n=6). For those with above target baseline HbA1c there was a small, statistically significant improvement (n=418, 8.4 ± 1.1% (69 ± 12 mmol/mol) to 8.2 ± 1.1% (66 ± 12 mmol/mol). HbA1c improvement was clinically significant among those in the highest baseline quartile (n=122, 9.7 ± 1.1% (82 ± 11 mmol/mol) to 9.0 ± 1.2% (75 ± 13 mmol/mol), p<0.001).

CONCLUSIONS

The proportion of participants reporting severe hypoglycaemia, DKA and severe diabetes-related distress was at least halved, and HbA1c reduced by 0.7% (7 mmol/mol) among those with highest baseline levels. Structured type 1 diabetes education delivered in routine practice offers clinically important benefits for those with greatest clinical need.

Evaluation of the performance of the OneTouch Select Plus blood glucose test system against ISO 15197:2013

OBJECTIVES

Assess laboratory and in-clinic performance of the OneTouch Select(®) Plus test system against ISO 15197:2013 standard for measurement of blood glucose.

METHODS

System performance assessed in laboratory against key patient, environmental and pharmacologic factors. User performance was assessed in clinic by system-naïve lay-users. Healthcare professionals assessed system accuracy on diabetes subjects in clinic.

RESULTS

The system demonstrated high levels of performance, meeting ISO 15197:2013 requirements in laboratory testing (precision, linearity, hematocrit, temperature, humidity and altitude). System performance was tested against 28 interferents, with an adverse interfering effect only being recorded for pralidoxime iodide. Clinic user performance results fulfilled ISO 15197:2013 accuracy criteria. Subjects agreed that the color range indicator clearly showed if they were low, in-range or high and helped them better understand glucose results.

CONCLUSION

The system evaluated is accurate and meets all ISO 15197:2013 requirements as per the tests described. The color range indicator helped subjects understand glucose results and supports patients in following healthcare professional recommendations on glucose targets.

Minimizing Hypoglycemia in Diabetes

Hypoglycemia caused by treatment with a sulfonylurea, a glinide, or insulin coupled with compromised defenses against the resulting falling plasma glucose concentrations is a problem for many people with diabetes. It is often recurrent, causes significant morbidity and occasional mortality, limits maintenance of euglycemia, and impairs physiological and behavioral defenses against subsequent hypoglycemia. Minimizing hypoglycemia includes acknowledging the problem; considering each risk factor; and applying the principles of intensive glycemic therapy, including drug selection and selective application of diabetes treatment technologies. For diabetes health-care providers treating most people with diabetes who are at risk for or are suffering from iatrogenic hypoglycemia, these principles include selecting appropriate individualized glycemic goals and providing structured patient education to reduce the incidence of hypoglycemia. This is typically combined with short-term scrupulous avoidance of hypoglycemia, which often will reverse impaired awareness of hypoglycemia. Clearly, the risk of hypoglycemia is modifiable.

Modeling predictors of changes in glycemic control and diabetes-specific quality of life amongst adults with type 1 diabetes 1 year after structured education in flexible, intensive insulin therapy

Few studies have identified determinants of glycemic control (HbA1c) and diabetes-specific quality of life (DSQoL) in adults with type 1 diabetes. To identify factors predicting outcomes following structured diabetes education. 262 participants completed biomedical and questionnaire assessments before, and throughout 1 year of follow-up. The proportion of variance explained ranged from 28 to 62 % (DSQoLS) and 14-20 % (HbA1c). When change in psychosocial variables were examined, reduced hypoglycemia fear, lower 'perceived diabetes seriousness', greater self-efficacy and well-being predicted QoL improvements from baseline to 3-months. Increased frequency of blood glucose testing predicted improvements in HbA1c from baseline to 6-months. Greater benefits may be achieved if programs focus explicitly on psychosocial factors. Self-care behaviours did not predict HbA1c suggesting existing assessment tools need refinement. Evaluation of treatment mechanisms in self-management programs is recommended.

Improving management of type 1 diabetes in the UK: the Dose Adjustment For Normal Eating (DAFNE) programme as a research test-bed. A mixed-method analysis of the barriers to and facilitators of successful diabetes self-management, a health economic analysis, a cluster randomised controlled trial of different models of delivery of an educational intervention and the potential of insulin pumps and additional educator input to improve outcomes

Background

Many adults with type 1 diabetes cannot self-manage their diabetes effectively and die prematurely with diabetic complications as a result of poor glucose control. Following the positive results obtained from a randomised controlled trial (RCT) by the Dose Adjustment For Normal Eating (DAFNE) group, published in 2002, structured training is recommended for all adults with type 1 diabetes in the UK.

Aim

With evidence that blood glucose control is not always improved or sustained, we sought to determine factors explaining why some patients benefit from training more than other patients, identifying barriers to successful self-management, while developing other models to make skills training more accessible and effective.

Findings

We confirmed that glycaemic outcomes are not always improved or sustained when the DAFNE programme is delivered routinely, although improvements in psychosocial outcomes are maintained. DAFNE courses and follow-up support is needed to help participants instil and habituate key self-management practices such as regular diary/record keeping. DAFNE graduates need structured professional support following training. This is currently either unavailable or provided ad hoc without a supporting evidence base. Demographic and psychosocial characteristics had minimal explanatory power in predicting glycaemic control but good explanatory power in predicting diabetes-specific quality of life over the following year. We developed a DAFNE course delivered for 1 day per week over 5 weeks. There were no major differences in outcomes between this and a standard 1-week DAFNE course; in both arms of a RCT, glycaemic control improved by less than in the original DAFNE trial. We piloted a course delivering both the DAFNE programme and pump training. The pilot demonstrated the feasibility of a full multicentre RCT and resulted in us obtaining subsequent Health Technology Assessment programme funding. In collaboration with the National Institute for Health Research (NIHR) Diabetes Research Programme at King’s College Hospital (RG-PG-0606-1142), London, an intervention for patients with hypoglycaemic problems, DAFNE HART (Dose Adjustment for Normal Eating Hypoglycaemia Awareness Restoration Training), improved impaired hypoglycaemia awareness and is worthy of a formal trial. The health economic work developed a new type 1 diabetes model and confirmed that the DAFNE programme is cost-effective compared with no structured education; indeed, it is cost-saving in the majority of our analyses despite limited glycated haemoglobin benefit. Users made important contributions but this could have been maximised by involving them with grant writing, delaying training until the group was established and funding users’ time off work to maximise attendance. Collecting routine clinical data to conduct continuing evaluated roll-out is possible but to do this effectively requires additional administrator support and/or routine electronic data capture.

Conclusions

We propose that, in future work, we should modify the current DAFNE curricula to incorporate emerging understanding of behaviour change principles to instil and habituate key self-management behaviours that include key DAFNE competencies. An assessment of numeracy, critical for insulin dose adjustment, may help to determine whether or not additional input/support is required both before and after training. Models of structured support involving professionals should be developed and evaluated, incorporating technological interventions to help overcome the barriers identified above and enable participants to build effective self-management behaviours into their everyday lives.

Effects of advanced carbohydrate counting in patients with type 1 diabetes: a systematic review

AIM

Advanced carbohydrate counting, a systematic method for insulin bolus calculation, is recommended in the management of type 1 diabetes. The aim of this systematic review was to summarize all available evidence from randomized and observational studies of the effects of advanced carbohydrate counting on glycaemic control (HbA(1c)), psychosocial measures, weight and hypoglycaemic events in patients of all age groups with type 1 diabetes on a basal-bolus insulin regimen.

METHODS

An electronic search of Scopus, MEDLINE and The Cochrane Library conducted in January 2013 identified 27 relevant articles. Six were randomized controlled trials and 21 were observational studies. Large heterogeneity existed across studies with regard to study design and patient populations. Reporting of statistical measures was insufficient to serve as a basis for a meta-analysis.

RESULTS

Overall, the studies demonstrated a positive trend in change in HbA(1c) after introduction of advanced carbohydrate counting. Reductions in HbA(1c) ranged from 0.0 to 13 mmol/mol (0.0-1.2%). Most psychosocial measures improved; however, only few improvements were considered clinically relevant. Both weight gain and reduction were registered, but most studies found no significant weight changes. The majority of studies assessing the incidence of hypoglycaemic events found a significant reduction in the event rate and none reported an increase in the incidence.

CONCLUSIONS

In summary, the currently available literature does not provide sufficient evidence to definitively determine the effects of advanced carbohydrate counting on HbA(1c), psychosocial measures, weight or hypoglycaemic events. Nevertheless, the method still appears preferable to other insulin dosing procedures, which justifies continued use and inclusion of advanced carbohydrate counting in clinical guidelines.

Use of clinical targets in diabetes patient education: qualitative analysis of the expectations and impact of a structured self-management programme in Type 1 diabetes

AIMS

To explore the impact of education and target-setting on the life stories of patients with diabetes up to 10 years after they had participated in the Dose Adjustment for Normal Eating programme (DAFNE).

METHODS

Qualitative, semi-structured interviews were conducted before and after DAFNE courses to elicit narrative accounts from participants at three UK education centres. Observations of courses also took place. Data were gathered from 21 participants over 32 interviews and 146 h of observations, and analysed using a narrative approach.

RESULTS

Findings suggest that patient education can create positive transformations in the lives of people with diabetes in ways that are not fully captured by simple quality-of-life scores. However, a review of evidence from other studies shows that DAFNE-recommended blood glucose results are in fact out of reach of even these most motivated and well-informed patients. This information was not shared with DAFNE attendees, who were expected to aim for near-normal HbA1c levels. After the course, participants sometimes perceived themselves as failing in their efforts, even when they had better than average blood glucose results.

CONCLUSIONS

Specific and measurable low HbA1c targets may be desirable for reducing the risk of complications in diabetes, but they are not attainable or realistic even for most DAFNE graduates. It is suggested that setting goals without information about how achievable they really are could be counterproductive in terms of supporting and maintaining patient self-efficacy long-term.

Type 1 diabetes patients' experiences of, and need for, social support after attending a structured education programme: a qualitative longitudinal investigation

AIMS AND OBJECTIVES

To explore patients' experiences of, views about and need for, social support after attending a structured education programme for type 1 diabetes.

BACKGROUND

Patients who attend structured education programmes attain short-term improvements in biomedical and quality-of-life measures but require support to sustain self-management principles over the longer term. Social support can influence patients' self-management practices; however, little is known about how programme graduates use other people's help.

DESIGN

This study was informed by the principles of grounded theory and involved concurrent data collection and analysis. Data were analysed using an inductive, thematic approach.

METHODS

In-depth interviews were undertaken postcourse, six and 12 months later, with 30 adult patients with type 1 diabetes recruited from Dose Adjustment for Normal Eating courses in the United Kingdom.

RESULTS

Patients' preferences for social support from other people ranged from wanting minimal involvement, to benefiting from auxiliary forms of assistance, to regular monitoring and policing. New self-management skills learnt on their courses prompted and facilitated patients to seek and obtain more social support. Support received/expected from parents varied according to when patients were diagnosed, but parents' use of outdated knowledge could act as a barrier to effective support. Support sought from others, including friends/colleagues, was informed by patients' domestic/employment circumstances.

CONCLUSION

This study responds to calls for deeper understanding of the social context in which chronic illness self-management occurs. It highlights how patients can solicit and receive more social support from family members and friends after implementing self-care practices taught on education programmes.

RELEVANCE TO CLINICAL PRACTICE

Health professionals including diabetes specialist nurses and dietitians should explore: patients' access to and preferences for social support; how patients might be encouraged to capitalise on social support postcourse; and new ways to inform/educate people within patients' social networks.

Use of a web 2.0 portal to improve education and communication in young patients with families: randomized controlled trial

Background

Diabetes requires extensive self-care and comprehensive knowledge, making patient education central to diabetes self-management. Web 2.0 systems have great potential to enhance health information and open new ways for patients and practitioners to communicate.

Objective

To develop a Web portal designed to facilitate self-management, including diabetes-related information and social networking functions, and to study its use and effects in pediatric patients with diabetes.

Methods

A Web 2.0 portal was developed in collaboration with patients, parents, and practitioners. It offered communication with local practitioners, interaction with peers, and access to relevant information and services. Children and adolescents with diabetes in a geographic population of two pediatric clinics in Sweden were randomized to a group receiving passwords for access to the portal or a control group with no access (n=230) for 1 year. All subjects had access during a second study year. Users’ activity was logged by site and page visits. Health-related quality of life (HRQOL), empowerment (DES), and quality of information (QPP) questionnaires were given at baseline and after 1 and 2 study years. Clinical data came from the Swedish pediatric diabetes quality registry SWEDIABKIDS.

Results

There was a continuous flow of site visits, decreasing in summer and Christmas periods. In 119/233 families (51%), someone visited the portal the first study year and 169/484 (35%) the second study year. The outcome variables did not differ between intervention and control group. No adverse treatment or self-care effects were identified. A higher proportion of mothers compared to fathers visited once or more the first year (P<.001) and the second year (P<.001). The patients who had someone in the family visiting the portal 5 times or more, had shorter diabetes duration (P=.006), were younger (P=.008), had lower HbA1c after 1 year of access (P=.010), and were more often girls (P<.001). Peer interaction seems to be a valued aspect.

Conclusions

The Web 2.0 portal may be useful as a complement to traditional care for this target group. Widespread use of a portal would need integration in routine care and promotion by diabetes team members.

Type 1 diabetes structured education: What are the core self-management behaviours?

AIMS

Study aims were to (1) describe and compare the way diabetes structured education courses have evolved in the UK, (2) identify and agree components of course curricula perceived as core across courses and (3) identify and classify self-care behaviours in order to develop a questionnaire assessment tool.

METHODS

Structured education courses were selected through the Type 1 diabetes education network. Curricula from five courses were examined and nine educators from those courses were interviewed. Transcripts were analysed using framework analysis. Fourteen key stakeholders attended a consensus meeting, to identify and classify Type 1 diabetes self-care behaviours.

RESULTS

Eighty-three courses were identified. Components of course curricula perceived as core by all diabetes educators were: carbohydrate counting and insulin dose adjustment, hypoglycaemia management, group work, goal setting and empowerment, confidence and control. The broad areas of self-management behaviour identified at the consensus meeting were carbohydrate counting and awareness, insulin dose adjustment, self-monitoring of blood glucose, managing hypoglycaemia, managing equipment and injection sites; and accessing health care. Specific self-care behaviours within each area were identified.

CONCLUSIONS

Planned future work will develop an updated questionnaire tool to access self-care behaviours. This will enable assessment of the effectiveness of existing structured education programmes at producing desired changes in behaviour. It will also help people with diabetes and their healthcare team identify areas where additional support is needed to initiate or maintain changes in behaviour. Provision of such support may improve glycaemia and reduce diabetes-related complications and severe hypoglycaemia.

Structured type 1 diabetes education delivered within routine care: impact on glycemic control and diabetes-specific quality of life

OBJECTIVE

To determine whether improvements in glycemic control and diabetes-specific quality of life (QoL) scores reported in research studies for the type 1 diabetes structured education program Dose Adjustment For Normal Eating (DAFNE) are also found when the intervention is delivered within routine U.K. health care.

RESEARCH DESIGN AND METHODS

Before and after evaluation of DAFNE to assess impact on glycemic control and QoL among 262 adults with type 1 diabetes.

RESULTS

There were significant improvements in HbA(1c) from baseline to 6 and 12 months (from 9.1 to 8.6 and 8.8%, respectively) in a subgroup with suboptimal control. QoL was significantly improved by 3 months and maintained at both follow-up points.

CONCLUSIONS

Longer-term improved glycemic control and QoL is achievable among adults with type 1 diabetes through delivery of structured education in routine care, albeit with smaller effect sizes than reported in trials.

Patients' experiences of adjusting insulin doses when implementing flexible intensive insulin therapy: a longitudinal, qualitative investigation

AIM

To explore patients' experiences of using flexible intensive insulin therapy, a regimen requiring them to determine and adjust quick-acting and background/basal insulin doses and mealtime ratios.

METHODS

Repeat, in-depth interviews with 30 type 1 diabetes patients converted to flexible intensive insulin therapy recruited from Dose Adjustment for Normal Eating (DAFNE) courses in the UK.

RESULTS

While patients found determination of quick acting insulin doses relatively straightforward, many struggled, over time, to determine the correct mealtime ratios and adjust basal insulin doses independently. Reasons included: lack of confidence and poor analytical skills; deferential attitudes to health professionals; worries about hypoglycaemia; and, lack of record/diary keeping resulting in fixation on current readings and failure to spot patterns and problems. When health professional support was not sought and/or record keeping neglected, patients gradually developed over-reliance on corrective doses to attain blood glucose readings within target ranges.

CONCLUSION

While patients are motivated to use flexible intensive insulin therapy, they expressed a need for on-going health professional input, particularly to support adjustment of background insulin doses and mealtime ratios. The need to sustain diary/record keeping should be emphasised to patients and provision of a dedicated glycaemic support service is recommended.

Supporting self-management after attending a structured education programme: a qualitative longitudinal investigation of type 1 diabetes patients' experiences and views

BACKGROUND

Structured education programmes for patients with diabetes and other chronic conditions are being widely adopted. However, follow-up studies suggest that course graduates may struggle to sustain the self-care practices taught on their courses over time. This study explored the support needs of patients with type 1 diabetes after attending a structured education programme promoting an empowerment approach and training in use of flexible intensive insulin therapy, a regimen now widely advocated and used to manage this condition. The objective was to inform future support offered to course graduates.

METHODS

Repeat, in-depth interviews with 30 type 1 diabetes patients after attending Dose Adjustment for Normal Eating (DAFNE) courses in the UK, and six and 12 months later. Data were analysed using an inductive, thematic approach.

RESULTS

While the flexible intensive insulin treatment approach taught on DAFNE courses was seen as a logical and effective way of managing one's diabetes, it was also considered more technically complex than other insulin regimens. To sustain effective disease self-management using flexible intensive insulin treatment over time, patients often expected, and needed, on-going input and support from health care professionals trained in the approach. This included: help determining insulin dose adjustments; reassurance; and, opportunities to trouble-shoot issues of concern. While some benefits were identified to receiving follow-up support in a group setting, most patients stated a preference or need for tailored and individualised support from appropriately-trained clinicians, accessible on an 'as and when needed' basis.

CONCLUSIONS

Our findings highlight potential limitations to group-based forms of follow-up support for sustaining diabetes self-management. To maintain the clinical benefits of structured education for patients with type 1 diabetes over time, course graduates may benefit from and prefer ongoing, one-to-one support from health care professionals trained in the programme's practices and principles. This support should be tailored and personalised to reflect patients' specific and unique experiences of applying their education and training in the context of their everyday lives, and could be the subject of future research.

Experiences of using blood glucose targets when following an intensive insulin regimen: a qualitative longitudinal investigation involving patients with Type 1 diabetes

AIMS

Use of blood glucose targets is considered essential to help patients with Type 1 diabetes achieve tight glycaemic control following structured education. To foster effective use of blood glucose targets, we explored patients' experiences and views of implementing clinically recommended blood glucose targets after attending a structured education programme promoting intensive insulin treatment.

METHODS

Repeat, in-depth interviews with 30 patients with Type 1 diabetes recruited from Dose Adjustment for Normal Eating (DAFNE) courses in the UK. Data were analysed using an inductive, thematic approach.

RESULTS

Patients found use of blood glucose targets motivational. Targets enabled patients to identify problems with blood glucose control and prompted them to make insulin dose adjustments independently, or with assistance. However, patients tended to adapt or simplify targets over time to: make them more attainable and easy to remember; reduce risk of hypoglycaemia; and, mitigate feelings of failure when attempts to attain clinically defined targets were unsuccessful. Some patients were advised to use elevated targets to counter hypoglycaemia unawareness and required help from health professionals to determine when/if these should be reduced.

CONCLUSIONS

Although blood glucose targets are an important component of diabetes self-management, patients may adapt and personalize them over time, sometimes inadvertently, with a potentially detrimental impact on long-term glycaemic control. Blood glucose targets should be regularly revisited during clinical reviews and revised/new targets agreed to accommodate patients' concerns and difficulties. Other interventions may need to be considered to promote effective use of blood glucose targets.

Glycaemic control and weight 7 years after Dose Adjustment For Normal Eating (DAFNE) structured education in Type 1 diabetes

AIMS

The provision of structured education is increasingly prevalent in the management of Type 1 diabetes. There are little long-term follow-up data from such programmes. We have assessed HbA(1c) and weight over a 7-year period following the Dose Adjustment For Normal Eating (DAFNE) structured education course.

METHODS

We obtained annual HbA(1c) and weight data in 111 patients who attended the initial series of DAFNE courses in our centre from June 2002 to end 2003 and in a matched group of 111 patients with Type 1 diabetes of similar age and duration of diabetes seen over the same period who had not undergone structured education.

RESULTS

With DAFNE structured education, the mean (± sd) HbA(1c) fell from 71 ± 12 mmol/mol (8.6 ± 1.1%) at baseline to 65 ± 12 mmol/mol (8.1 ± 1.1%) at year 1, with a subsequent rise to 67 ± 13 mmol/mol (8.3 ± 1.2%) at year 7 (P = 0.0048 vs. baseline). In the comparator group, the baseline HbA(1c) level was 70 ± 14 mmol/mol (8.5 ± 1.3%) and remained approximately constant during 7 years of follow-up. Weight increased by 2.4 ± 6.0 and 2.8 ± 6.6 kg in the DAFNE and comparator group, respectively, during follow-up (not significant).

CONCLUSIONS

DAFNE structured education is associated with an improvement in glycaemic control at 1 year, and there remains a persistent and clinically relevant reduction in HbA(1c) of 3 mmol/mol (0.3%) after 7 years. The improvement in glycaemic control after DAFNE is achieved without excess weight gain.

Use of an automated bolus calculator in MDI-treated type 1 diabetes: the BolusCal Study, a randomized controlled pilot study

OBJECTIVE

To investigate the effect of flexible intensive insulin therapy (FIIT) and an automated bolus calculator (ABC) in a Danish type 1 diabetes population treated with multiple daily injections. Furthermore, to test the feasibility of teaching FIIT in a 3-h structured course.

RESEARCH DESIGN AND METHODS

The BolusCal Study was a 16-week randomized, controlled, open-label, three-arm parallel, clinical study of 51 adults with type 1 diabetes. Patients aged 18-65 years in poor metabolic control (HbA(1c) 8.0-10.5%) were randomized to the Control (n = 8), CarbCount (n = 21), or CarbCountABC (n = 22) arm. During a 3-h group teaching, the Control arm received FIIT education excluding carbohydrate counting. CarbCount patients were taught FIIT and how to count carbohydrates. CarbCountABC group teaching included FIIT and carbohydrate counting and patients were provided with an ABC.

RESULTS

At 16 weeks, the within-group change in HbA(1c) was -0.1% (95% CI -1.0 to 0.7%; P = 0.730) in the Control arm, -0.8% (-1.3 to -0.3%; P = 0.002) in the CarbCount arm, and -0.7% (-1.0 to -0.4%; P < 0.0001) in the CarbCountABC arm. The difference in change in HbA(1c) between CarbCount and CarbCountABC was insignificant. Adjusting for baseline HbA(1c) in a regression model, the relative change in HbA(1c) was -0.6% (-1.2 to 0.1%; P = 0.082) in CarbCount and -0.8% (-1.4 to -0.1%; P = 0.017) in CarbCountABC. Treatment satisfaction measured by the Diabetes Treatment Satisfaction Questionnaire (status version) improved in all study arms, but the improvement was significantly greater in CarbCountABC.

CONCLUSIONS

FIIT and carbohydrate counting were successfully taught in 3 h and improved metabolic control and treatment satisfaction. Concurrent use of an ABC improved treatment satisfaction further.

Patient experience of hypoglycaemia unawareness in Type 1 diabetes: are patients appropriately concerned?

OBJECTIVE

Risk of severe hypoglycaemia is increased by absence of subjective awareness of hypoglycaemia and reduced by avoidance of minor hypoglycaemia. For many, problems persist despite educational strategies that work for others. We explored psychological factors that might inhibit the efforts of an individual in hypoglycaemia avoidance.

METHODS

People with Type 1 diabetes and hypoglycaemia unawareness gave semi-structured interviews exploring their perceptions and experiences of their condition. Identified factors were grouped into categories and analysed to establish links and form a grounded theory in a constant comparative analysis. A questionnaire was devised from the qualitative analysis to identify patients with problematic beliefs about their hypoglycaemia.

RESULTS

Saturation (no new themes emerging) was reached with 17 patients. Responses fell into two groups: high concern and low concern regarding hypoglycaemia unawareness. Those in the first group described severe hypoglycaemia as aversive and wanted to regain awareness. The second group included three patients in whom unawareness was not associated with severe hypoglycaemia, nevertheless unhelpful attitudes which inhibited hypoglycaemia avoidance were expressed. Responses from this group fell into categories: (1) normalizing the presence of unawareness; (2) underestimating its consequences; (3) wanting to avoiding the 'sick role'; and (4) overestimating the consequences of hyperglycaemia.

CONCLUSIONS

A qualitative analysis of patient interviews identified deficits in education, technology and motivation in hypoglycaemia unawareness. Interventions can therefore be tailored to target underlying problems that prevent individual patients from regaining awareness. A brief assessment tool was devised to categorize patients' hypoglycaemia unawareness accordingly. Psychological interventions should be developed to address the problems of 'low concern' regarding hypoglycaemia unawareness.

How and why do patients with Type 1 diabetes sustain their use of flexible intensive insulin therapy? A qualitative longitudinal investigation of patients' self-management practices following attendance at a Dose Adjustment for Normal Eating (DAFNE) course

BACKGROUND

Conventional insulin therapy requires patients with Type 1 diabetes to adhere to rigid dietary and insulin injection practices. Recent trends towards flexible intensive insulin therapy enable patients to match insulin to dietary intake and lifestyle; however, little work has examined patients' experiences of incorporating these practices into real-life contexts. This qualitative longitudinal study explored patients' experiences of using flexible intensive insulin therapy to help inform the development of effective long-term support.

METHODS

Semi-structured interviews were conducted with 30 adult patients with Type 1 diabetes following participation in a structured education programme on using flexible intensive insulin therapy, and 6 and 12 months post-course. Longitudinal data analysis used an inductive, thematic approach.

RESULTS

Patients consistently reported feeling committed to and wanting to sustain flexible intensive insulin therapy. This regimen was seen as a logical and effective method of self-management, as patients experienced improved blood glucose readings and/or reported feeling better. Implementing and sustaining flexible intensive insulin therapy was enhanced when patients had stable routines, with more challenges reported by those working irregular hours and during weekends/holidays. Some patients re-crafted their lives to make this approach work for them; for instance, by creating dietary routines or adjusting dietary choices.

CONCLUSIONS

Clinical data have shown that flexible intensive insulin therapy can lead to improvement in glycaemic control. This study, drawing on patients' perspectives, provides further endorsement for flexible intensive insulin therapy by demonstrating patients' liking of, and their motivation to sustain, this approach over time. To help patients implement and sustain flexible intensive insulin therapy, follow-up support should encourage them to identify routines to better integrate this regimen into their lives.

Dose Adjustment for Normal Eating: a qualitative longitudinal exploration of the food and eating practices of type 1 diabetes patients converted to flexible intensive insulin therapy in the UK

AIM

To explore whether, and why, patients change their food and eating practices following conversion to flexible intensive insulin therapy (FIIT), a regimen which requires quick acting insulin doses to be matched to the carbohydrate content of meals/snacks consumed.

METHODS

repeat, in-depth interviews with 30 type 1 diabetes patients converted to FIIT recruited from Dose Adjustment for Normal Eating (DAFNE) courses in the UK. Data were analysed using an inductive, thematic approach.

RESULTS

despite the potential of FIIT to enable greater dietary flexibility and freedom, most patients reported food and eating practices which were remarkably resistant to change. In some cases, FIIT adoption resulted in greater dietary rigidity over time. The opportunities FIIT presented for greater dietary freedom were counterbalanced by new challenges and burdens (e.g. having to simplify food choices to make carbohydrate estimation easier). Due to the emphasis FIIT places on carbohydrate counting, and patients' fears of hypos, low/no carbohydrate foodstuffs sometimes came to be seen as the healthiest or safest options.

CONCLUSION

concerns that FIIT may result in more excessive or unhealthy eating appear largely unfounded; however, consideration needs to be paid to the ways in which patients' conceptualisations of, and relationship with, food may change following FIIT conversion.

Long-term impact of a structured group-based inpatient-education program for intensive insulin therapy in patients with diabetes mellitus

PURPOSE

Structured patient education aiming to improve self-management strategies might be beneficial for insulin-treated diabetic patients. However, in previous studies the extent of the benefit has been inconsistent in different subgroups of patients. The aim of the present study was to assess the potential benefit of a structured inpatient-education program for intensive insulin therapy according to the basal-bolus concept with particular emphasis on self-management strategies.

METHODS

We included 81 diabetic patients (59 with type 1, 14 with type 2, eight with other forms) in this retrospective longitudinal study; all had completed the training program on eight consecutive days at a university clinic between 2003 and 2005. Data assessment included HbA1c, LDL-cholesterol, HDL-cholesterol and BMI at baseline (0-15 months before the training) and after 0-5, 5-10 and 10-20 months.

RESULTS

A transient decrease of HbA1c (0.2%, 95% CI: 0.04-0.37, P = 0.017) and LDL-cholesterol levels (9.95 mg/dl, 95% CI: 2.24-17.76, P = 0.013) between baseline and the first follow-up examination was observed in the group overall. Thereafter, HbA1c and LDL-cholesterol were similar to baseline, whereas a persistent increase in HDL-cholesterol (P = 0.025) was evident in the multivariable analysis. No changes in BMI were observed. A significant type-by-time interaction (P = 0.008) in HbA1c suggests a long-term benefit in glycemic control in patients with type 2 diabetes.

CONCLUSION

A diabetes training program for intensive insulin therapy with particular emphasis on self-management skills was followed by a moderate and transient improvement of glycemic control and LDL-cholesterol and by a persistent increase in HDL-cholesterol. Long-term improvement in glycemic control was observed only in patients with type 2 diabetes.

Hub-and-spoke model for a 5-day structured patient education programme for people with Type 1 diabetes

AIMS

Structured education programmes for people with Type 1 diabetes can deliver improved diabetes control (including reduced severe hypoglycaemia) and quality of life. They can be cost-effective but are resource intensive. We tested the ability to deliver an evidence-based 5-day programme in diabetes centres too small to deliver the courses.

METHODS

Specialist medical and nursing staff from three district general hospital diabetes services (the 'spokes') were trained in all aspects of the education programme, except those directly related to course delivery, by a larger centre (the 'hub'). The hub staff delivered the 5-day patient education courses, but all other patient education and management was managed locally. Diabetes control and quality of life were assessed at 1 year post-course.

RESULTS

In 63 patients with follow-up data, glycated haemoglobin (HbA(1c)) fell by 0.42 +/- 1.0% (P = 0.001), with a greater fall in those with high HbA(1c) at baseline, and no mean weight gain. Emergency call-out for severe hypoglycaemia fell from 10 episodes in seven patients the year before to one episode in one patient (P = 0.03). Quality-of-life measures improved, with reduced negative impact of diabetes on diabetes-related quality of life (P < 0.00004) and 'present quality of life' improving (P < 0.001).

CONCLUSIONS

The benefits of a 5-day structured education programme can be provided to patients with Type 1 diabetes attending centres without the resources to provide the teaching course itself, by a 'hub-and-spoke' methodology.
