Clinical skills: empowering people with diabetes to minimize complications

A Brief Overview of the Oral Delivery of Insulin as an Alternative to the Parenteral Delivery

Diabetes mellitus greatly affects the quality of life of patients and has a worldwide prevalence. Insulin is the most commonly used drug to treat diabetic patients and is usually administered through the subcutaneous route. However, this route of administration is ineffective due to the low concentration of insulin at the site of action. This route of administration causes discomfort to the patient and increases the risk of infection due to skin barrier disturbance caused by the needle. The oral administration of insulin has been proposed to surpass the disadvantages of subcutaneous administration. In this review, we give an overview of the strategies to deliver insulin by the oral route, from insulin conjugation to encapsulation into nanoparticles. These strategies are still under development to attain efficacy and effectiveness that are expected to be achieved in the near future.

The Outcome of Structured Education in Adults With Type 2 Diabetes Mellitus and Substance Use Disorder: A Literature Review

OBJECTIVE

Structured diabetes education for patients is a cornerstone of therapy; it empowers the patients by giving them appropriate tools for the self-management of the illness. The objective of this work was to determine how substance use disorder influences the outcome of structured diabetes education in patients with type 2 diabetes mellitus, and whether patients with substance use disorder are less likely to benefit because of their addiction issues.

METHODS

Only clinical trials involving substance use, which were randomized, in the context of type 2 diabetes mellitus were included.

RESULTS

Literature was only available for alcohol use disorder, and there were no studies available on any other recreational substance use disorders and its effects on structured diabetes education. Out of 3 relevant studies, in the context of alcohol use disorder, 2 studies identified alcohol use by the patients as a limiting factor in receiving structured diabetes education. One study did not show any impact of alcohol on structured diabetes education.

CONCLUSIONS

More high-quality randomized controlled trials with better sample sizes are required to say with confidence if alcohol use affects the patient's ability to participate in structured educational programs for type 2 diabetes mellitus management.

Diabetes knowledge of nurses in different countries: An integrative review

OBJECTIVE

The aim of this study was to identify, critically appraise and synthesise evidence of nurses' knowledge of diabetes and identify factors that function as barriers to nurses' acquisition of diabetes knowledge.

DESIGN

An integrative review

METHODS

A systematic search was conducted for English-language, peer reviewed publications of any research design via CINAHL, Medline, EMBASE, and Education Research Complete databases from 2004 to 2014. Of 374 articles retrieved, after removal of duplicates and quality appraisal, 25 studies were included in the review and synthesised based on study characteristics, design and findings.

FINDINGS

Studies originated from developed and developing countries and applied a variety of research designs and tools to assess nurses' knowledge of diabetes. Assessed aspects of diabetes care included knowledge of diabetes medications (12 studies), nutrition (7), blood glucose monitoring (7), diabetes complications (6), and pathology, symptoms and diabetes management (9). Factors/barriers affecting nurses' acquisition of diabetes knowledge were identified (11). Overall, findings indicated wide-spread serious and sustained deficiencies in nurses' knowledge of diabetes and diabetes care.

CONCLUSION

With nurses demonstrating significant and long-standing knowledge deficits in many aspects of diabetes care, strategies are urgently required to overcome the identified barriers to knowledge acquisition.

An expanded model of diabetes care based in an analysis and critique of current approaches

AIMS AND OBJECTIVES

To examine and critique various models guiding the care and education of people with diabetes, to develop more helpful and effective approaches to care. The focus is on relationships and communication between patients and healthcare providers.

BACKGROUND

Many patients are not adhering to the recommended treatments, hence it seems that effective diabetes care is difficult to achieve, particularly for patients of lower socio-economic status, who are disproportionately afflicted. The results are usually devastating, and lead to serious health complications that incisively diminish quality of life for patients with diabetes, frustrate healthcare providers and increase healthcare costs.

DESIGN

Critical review.

METHOD

This paper represents a critical review of various approaches to diabetes care and education. A CINAHL search with relevant key words was carried out and selected exemplary research studies and articles describing and/or evaluating the various approaches to diabetes care and management were examined. Particular attention was paid to how the paradigmatic underpinnings of these approaches construct patient - healthcare provider relationships.

CONCLUSION

The literature revealed that the traditional top-down approaches to care were largely ineffective, while collaborative approaches, based in respect and taking the whole persons and their unique situations into account, were found to be central to good care. Further, an integration of the different kinds of knowledge contained in the various approaches can complement and extend one another.

RELEVANCE TO CLINICAL PRACTICE

Avoiding devastating complications by improving the management of diabetes and overall quality of life of patients is a worthwhile goal. Therefore expanding diabetes care beyond the traditional bio-medical model to develop more effective approaches to care is of interest to all healthcare professionals working in this area.

Returning of the diabetic patients who loss follow-up for more than 1 year: what is the reason?

The loss follow-up is the big problem preventing the success in diabetic management. Each year, several diabetic patients loss follow-up and this can be the cause of complicated diabetic cases. Although there are some previous reports on the reason for loss follow-up of diabetic patient there has never been report on the reason for returning to revisit the physician in charge. Here, the author reports on the experience among returning 50 diabetic patients who loss follow-up for more than 1 year. The result can be basic information for better understand the nature of patient compliance to diabetic management program.

In pursuit of excellence in diabetes care: trends in insulin delivery

Diabetes mellitus has been estimated to affect 2.9 million people in the UK. Large-scale clinical trials conclusively demonstrate that elevated blood glucose levels are associated with an increased risk of micro- and macrovascular complications. The high rates of morbidity and mortality associated with this condition demonstrate how important effective glycaemic control is. Subcutaneous insulin injection continues to be the mainstay of therapy for all people with type 1 diabetes mellitus and the majority of individuals with type 2 diabetes mellitus. However, there are a number of barriers to insulin therapy. For example, conventional insulin delivery is arguably time consuming. Furthermore, it has been associated with common errors, such as inaccurate dosing and administration (National Patient Safety Agency, 2010). Insulin pen devices have various advantages over conventional delivery. Their ease of use and incorporation into busy lifestyles may improve diabetes control with much less effort, while maintaining adherence and quality of life. Research in insulin delivery shows there is a prospect of needle-free delivery in the near future. Despite such progress, the role of the healthcare professionals in involving, assessing, supporting and educating people having insulin therapy, including the attainment of the agreed blood glucose levels, cannot be overestimated.

Diabetes Empowerment Process Scale: development and psychometric testing of the Chinese version

AIM

This paper is a report of the development and psychometric testing of the Chinese version of the Diabetes Empowerment Process Scale.

BACKGROUND

In people living with diabetes, empowerment can improve metabolic and psychosocial outcomes. A scale for measuring empowerment processes can also help healthcare professionals to optimize their empowering actions and would improve their interactions with people living with diabetes.

METHOD

Based on literature reviews and interviews with people living with diabetes, a 27-item Chinese Diabetes Empowerment Process Scale was developed. Fifteen items were produced after item analysis and content validity testing. To test construct validity, concurrent validity and internal consistency, 211 outpatients living with diabetes completed the Chinese Diabetes Empowerment Process Scale, a Self-care Behaviour Scale and a Diabetes Empowerment Scale. Test-retest reliability was also analysed with 30 patients. The study was conducted in 2008 and 2009 in Taiwan.

RESULTS

Confirmatory factor analysis indicated that a second-order factorial model with four subscales and 15 items best fitted the data. The four subscales were Mutual participation, Raising awareness, Providing necessary information and Open communication. Scores on the Chinese Diabetes Empowerment Process Scale correlated statistically significantly with those on the Self-care Behaviour Scale (r=0.21-0.40; P<0.01) and Diabetes Empowerment Scale (r=0.35-0.65; P<0.01). Reliability was supported by acceptable Cronbach's α (range: 0.73-0.91) and test-retest reliability scores (range: 0.75-0.83).

CONCLUSION

The Chinese Diabetes Empowerment Process Scale has satisfactory validity and reliability for measuring the empowerment process of health professionals. Further studies are needed to test the applicability of the scale to other populations.

The missing link: paediatric to adult transition in diabetes services

Childhood diabetes is a chronic and life-changing condition requiring careful management by clinicians, the child and family. During childhood, care is provided by the paediatric team, which is then transferred to the adult diabetes team during adolescence. This literature review identified five themes in the literature: adolescence as a time of transition; adolescent needs during transition; barriers; facilitators; and models of transition. Key findings suggest that the transition process remains problematic with a gap between paediatric and adult services being identified, including significant differences in clinical practice and culture. Although there is a growing body of knowledge around the reasons behind this phenomenon, research into effective models of transition to address these problems is still lacking. A period of managed transition between the two services has been recommended, with evidence that the nurse has the potential to develop a coordinating role, to assist in bridging the gap between paediatric and adult services.

An epidemiological overview of diabetes across the world

Once the Cinderella of chronic diseases, diabetes mellitus is now fast emerging as one of the biggest health catastrophes the world has ever witnessed. Almost 6% of the world's adult population now live with diabetes (Sicree et al, 2003; International Federation of Diabetes, 2006). It has been predicted that the total number of people with diabetes will rise to 366 million in less than 30 years if preventative action is not taken (Wild et al, 2004). Diabetes is no longer a concern of an individual country. It has huge global and societal implications, particularly in developing countries where the development of diabetes at an early age can lead to untoward human suffering, disability and socioeconomic cost. An internationally coordinated effort is required to improve human behaviour and lifestyle to halt the global diabetes epidemic and the development of such complications as retinopathy, nephropathy, neuropathy, cardiovascular diseases, peripheral vascular diseases and stroke. For such a formula to be successful, it is important for nurses to be proactive in their political role in ensuring that people with diabetes become expert in their condition. In so doing, healthcare systems and resources could be used more effectively to reduce real human and economic costs.

Dietary pattern of self-care among Asian and Caucasian diabetic patients

Diabetes mellitus is a growing pandemic and its self-care management rests primarily with the individual. This qualitative case study investigated the self-care dietary pattern among a group of 25 Asians and 24 Caucasians diagnosed with type 1 or type 2 diabetes. Data collected from a semi-structured interview and a 7-day health diary explored the self-care activities undertaken by the participants to establish metabolic control. From an analytical perspective, the collective responses were placed on a continuum ranging from strict adherence, moderately flexible adherence to very flexible adherence. The findings suggest that most of the participants were located in the latter two categories of diet related to self-care. Implications for healthcare professionals in promoting self-care will be discussed.
