Application of Australian clinical management guidelines: the current state of play in a sample of young people living with Type 1 diabetes in the state of New South Wales and the Australian Capital Territory

Assessing guideline adherence in the management of type 1 diabetes mellitus in Australian children: a population-based sample survey

INTRODUCTION

To estimate adherence to clinical practice guidelines in selected settings at a population level for Australian children with type 1 diabetes mellitus.

RESEARCH DESIGN AND METHODS

Medical records of children with type 1 diabetes mellitus aged 0-15 years in 2012-2013 were targeted for sampling across inpatient, emergency department and community visits with specialist pediatricians in regional and metropolitan areas and tertiary pediatric hospitals in three states where approximately 60% of Australian children reside. Clinical recommendations extracted from two clinical practice guidelines were used to audit adherence. Results were aggregated across types of care (diagnosis, routine care, emergency care).

RESULTS

Surveyors conducted 6346 indicator assessments from an audit of 539 healthcare visits by 251 children. Average adherence across all indicators was estimated at 79.9% (95% CI 69.5 to 88.0). Children with type 1 diabetes mellitus have higher rates of behavioral and psychological disorders, but only a third of children (37.9%; 95% CI 11.7 to 70.7) with suboptimal glycemic control (eg, hemoglobin A1c >10% or 86 mmol/mol) were screened for psychological disorders using a validated tool; this was the only indicator with <50% estimated adherence. Adherence by care type was: 86.1% for diagnosis (95% CI 76.7 to 92.7); 78.8% for routine care (95% CI 65.4 to 88.9) and 83.9% for emergency care (95% CI 78.4 to 88.5).

CONCLUSIONS

Most indicators for care of children with type 1 diabetes mellitus were adhered to. However, there remains room to improve adherence to guidelines for optimization of practice consistency and minimization of future disease burden.

Diabetes Educators' Intended and Reported Use of Common Diabetes-Related Technologies: Discrepancies and Dissonance

BACKGROUND

Technology provides adjuvant and/or alternative approaches to care and may promote self-care, communication, and engagement with health care services. Common recent technologies for diabetes include continuous subcutaneous insulin infusions (insulin pumps), continuous glucose monitoring systems, smartphone and tablet applications, and telehealth (video conferencing). This study reports Australian diabetes educators' intentions and reported professional use of these technologies for people with type 1 diabetes, and factors predictive of this.

METHODS

An anonymous, web-based questionnaire based on the technology acceptance model was distributed to members of the Australian Diabetes Educators Association through their electronic newsletter. Exploratory factor analysis revealed a 5-factor solution comprising confidence and competence, improving clinical practice, preparation (intentions and training), ease of use, and subjective norms. Logistic regression analyses identified factors predicting intention and use of technology.

RESULTS

Respondents (n = 228) had high intentions to use technology. The majority reported using continuous subcutaneous insulin infusions, continuous glucose monitoring systems, and applications with patients, but usage was occasional. Confidence and competence independently predicted both intentions and use of all 4 technologies. Preparation (intentions and training) independently predicted use of each technology also.

CONCLUSIONS

Discrepancies and dissonance appear between diabetes educators' intentions and behavior (intentions to use and reported technology use). Intentions were higher than current use, which was relatively low and not likely to provide significant support to people with type 1 diabetes for disease management, communication, and engagement with health care services. Continuing education and experiential learning may be key in supporting diabetes educators to align their intentions with their practice.

Prevalence of vascular complications and factors predictive of their development in young adults with type 1 diabetes: systematic literature review

Background

Vascular complications curtail life expectancy and quality of life in type 1 diabetes and development at younger ages is particularly detrimental. To date no review has summarised the prevalence or factors predicting their development in young adults.

Methods

A quantitative epidemiological systematic review was conducted to identify the prevalence and predictive factors for development of retinopathy, nephropathy and hypertension in young adults (sample age mean [plus 1SD] 18–30 years) with type 1 diabetes, using processes adapted from established review methods set out by the Centre for Reviews and Dissemination.

MEDLINE (Ovid), Scopus (Elsevier), CINAHL, Science Direct (Elsevier), Google Scholar and Cochrane databases were searched to identify relevant articles published between 1993 and June 2014. From this eleven papers were retrieved, appraised and results summarised by three reviewers using established methods.

Results

Some form of retinopathy occurred in up to almost half of participants; more severe forms affected up to one in ten. One in six was reported with microalbuminuria; one in 14 had macroalbuminuria. Hypertension occurred in almost one in two participants. Applying out-dated high thresholds this decreased to approximately one in ten participants. Glycaemic control was a consistent predictor of vascular disease in this age group.

Conclusion

Prevalence rates of retinopathy, nephropathy and hypertension in young adults with type 1 diabetes emphasise the importance of regular complication screening for early detection and treatment. The predictive effect of glycaemic control reinforces its importance for prevention of vascular complications.

The outcome of care in people with type 1 diabetes after switching to insulin glargine-based regimens in a real-life setting: a long-term observational study

BACKGROUND

Different insulin preparations are used as basal insulins in type 1 diabetes. The aim of this study was to assess long-term efficacy and safety of insulin glargine after switching from other basal insulins in type 1 diabetes in a real-life setting.

METHODS

In the clinic's database, 87 subjects treated with glargine for > 1 year were identified. In all patients, HbA1c level, insulin doses, episodes of severe hypoglycaemia, diabetic complications, comorbidities, body mass index (BMI), blood pressure and concomitant medications' use were monitored throughout the entire follow-up period.

RESULTS

During observation, lasting mean 61.9 ± 27.6 months HbA1c level decreased from 8.86 ± 1.60% (73.3 mmol/mol) to 8.25 ± 1.40% (66.7 mmol/mol), p < 0.001. This improvement was maintained up to 8 years. Frequency of severe hypoglycaemia was 6.24/100 patient-years. Total insulin requirement did not changed significantly. BMI increased from 23.57 ± 2.90 to 24.52 ± 3.46 kg/m(2) (p < 0.001). Significant weight gain (> 5%) occurred in 30 subjects, while 10 patients lost weight. Mean systolic blood pressure (SBP) increased from 136.3 ± 13.4 to 140.7 ± 15.1 mmHg (p = 0.008), while diastolic blood pressure remained unchanged. Development or progression of diabetic complications was revealed in 11 subjects.

CONCLUSIONS

Following switch from other basal insulins to insulin glargine in type 1 diabetic patients, glycaemic control significantly improved, with unchanged total insulin requirement and with low risk of severe hypoglycaemia. Weight gain and elevation of SBP observed in this study require special attention and educational efforts. In summary, insulin glargine can be recommended as an effective and safe basal insulin in type 1 diabetes in a real-life setting.

Geography does not limit optimal diabetes care: use of a tertiary centre model of care in an outreach service for type 1 diabetes mellitus

AIM

Young people with type 1 diabetes mellitus living in rural and regional Australia have previously been shown to have limited access to specialised diabetes services. The Royal Children's Hospital Melbourne has been running diabetes outreach clinics to Western Victoria, Australia, for over 13 years. We aim to evaluate this service by comparing the outcomes of three outreach clinics with our urban diabetes clinic at the Royal Children's Hospital Melbourne.

METHODS

We examine our tertiary, multidisciplinary team-based model of care, where visiting specialist medical staff work alongside local allied health teams. The local teams provide interim care between clinics utilising the same protocols and treatment practices as the tertiary centre. Longitudinal data encapsulating the years 2005-2010, as a cohort study with a control group, are reviewed.

RESULTS

A total of 69 rural patients were compared with 1387 metropolitan patients. Metabolic control was comparable, with no difference in mean HbA1c (8.3%/67 mmol/mol for both groups). Treatment options varied slightly at diagnosis, while insulin pump usage was comparable between treatment settings (20.3% rural compared with 27.6% urban, P = 0.19). Of note was that the number of visits per year was higher in the rural group (3.3 per year rural compared with 2.7 urban, P < 0.001).

CONCLUSIONS

We conclude that the outreach service is able to provide a comparable level of care when the urban model is translated to a rural setting. This model may be further able to be extrapolated to other geographic areas and also other chronic health conditions of childhood.

Service usage and vascular complications in young adults with type 1 diabetes

BACKGROUND

Few studies have examined young adults with type 1 diabetes use of health services and the development of vascular complications. As part of the Youth Outreach for Diabetes (YOuR-Diabetes) project, this study identified health service usage, the prevalence and factors predictive of development of vascular complications (hypertension, retinopathy and nephropathy) in a cohort of young adults (aged 16-30 years) with type 1 diabetes in Hunter New England and the Lower Mid-North Coast area of New South Wales, Australia.

METHODS

A cross-sectional retrospective documentation survey was undertaken of case notes of young adults with type 1 diabetes accessing Hunter New England Local Health District public health services in 2010 and 2011, identified through ambulatory care clinic records, hospital attendances and other clinical records. Details of service usage, complications screening and evidence of vascular complications were extracted. Independent predictors were modelled using linear and logistic regression analyses.

RESULTS

A cohort of 707 patients were reviewed; mean (SD) age was 23.0 (3.7) years, with mean diabetes duration of 10.2 (5.8, range 0.2 - 28.3) years; 42.4% lived/ 23.1% accessed services in non-metropolitan areas.Routine preventative service usage was low and unplanned contacts high; both deteriorated with increasing age. Low levels of complications screening were found. Where documented, hypertension, particularly, was common, affecting 48.4% across the study period. Diabetes duration was a strong predictor of vascular complications along with glycaemic control; hypertension was linked with renal dysfunction.

CONCLUSION

Findings indicate a need to better understand young people's drivers and achievements when accessing services, and how services can be reconfigured or delivered differently to better meet their needs and achieve better outcomes. Regular screening is required using current best practice guidelines as this affords the greatest chance for early complication detection, treatment initiation and secondary prevention.

Glycemic control and blood glucose monitoring over time in a sample of young Australians with type 1 diabetes: the role of personality

OBJECTIVE

To determine whether personality traits (conscientiousness, agreeableness, emotional regulation, extraversion, and openness to experience) are associated with glycemic control and blood glucose monitoring behavior, and change or stability of these outcomes over time, in young people with type 1 diabetes.

RESEARCH DESIGN AND METHODS

A 3-year longitudinal study was conducted using data from 142 individuals with type 1 diabetes, 8-19 years of age. Personality was assessed at baseline using the Five-Factor Personality Inventory for Children. Data relating to glycemic control (HbA1c) and frequency of blood glucose monitoring (based on meter memory) were collected annually. Relationships between personality traits and HbA1c and monitoring frequency were examined using regression models and mixed-design ANOVA.

RESULTS

Three of the Five-Factor domains were independently associated with glycemic control. Individuals high in conscientiousness and agreeableness had a lower and more stable HbA1c across the 3-year study period. In contrast, the HbA1c of individuals scoring low on these traits was either consistently worse or deteriorated over time. Low or high emotional regulation scores were also associated with worse glycemic control. By the third year, these domains, together with initial HbA1c, accounted for 39% of HbA1c variance. Conscientiousness was the only personality factor associated with blood glucose monitoring behavior.

CONCLUSIONS

Results of this study underline the importance of personality in contributing to diabetes outcomes. Attention to a young person's personality, and appropriate tailoring of diabetes management to ensure an individualized approach, may help to optimize diabetes outcomes.

Services doing the best they can: service experiences of young adults with type 1 diabetes mellitus in rural Australia

AIMS AND OBJECTIVES

To describe the healthcare experiences of young adults with type 1 diabetes who access diabetes services in rural areas of New South Wales, Australia.

BACKGROUND

The incidence of type 1 diabetes in childhood and adolescence is increasing worldwide; internationally, difficulties are encountered in supporting young people during their transition from children to adulthood. Consumers' experiences and views will be essential to inform service redesign.

DESIGN

This was a qualitative exploratory study.

METHODS

Semistructured telephone interviews were conducted with 26 people aged 18-28 years living rurally, recruited through staff in four regional healthcare centres in 2008.

RESULTS

Two key themes were evident: lack of access (comprised of transfer to adult services, access to health professionals and access to up-to-date information) and age-appropriate provision. The impact of place of residence and personal motivation crossed all themes. Participants contrasted unfavourably the seamless care and support received from paediatric outreach services with the shortages in specialist and general practice-based care and information and practical problems of service fragmentation and lack of coordination experienced as adults. They identified a range of issues including need for ongoing education, age-appropriate services and support networks related to developing their ability to self-manage. They valued personal service; online and electronic support was seldom volunteered as an alternative.

CONCLUSION

This was a first view of rural young people's experiences with adult diabetes services. Reported experiences were in line with previous reports from other settings in that they did not perceive services in this rural area of Australia as meeting their needs; suggestions for service redesign differed.

RELEVANCE TO CLINICAL PRACTICE

New models of age-appropriate service provision are required, to meet their needs for personal as well as other forms of support, whilst acknowledging the very real resource limitations of these locations.
