Diabetes mellitus: lessons from patient education

The Challenges of Iran's Type 2 Diabetes Prevention and Control Program

Background:

Incidence and prevalence of type 2 diabetes are one of the major challenges of Iran health system. Despite policies on diabetes prevention and control, Iran is faced with many problems in prevention and control of this disease at the executive level. This study seeks to identify the problems of Type 2 diabetes prevention and control program in Iran.

Methods:

In this qualitative study, 17 participants were interviewed purposefully. The semi-structured interview guide was designed based on literature review and four initial in-depth interviews. Framework analysis method was used for the analysis of qualitative data.

Results:

Six themes and 29 subthemes explaining the problems of type 2 diabetes prevention and control program were identified: Referral system, human resources, infrastructure, cultural problems, access, and intersectoral coordination issues.

Conclusions:

Despite the well-developed policy of type 2 diabetes prevention and control, the implementation is faced with some problems which endangers the effectiveness of the plan. Any attempt to improve the successful implementation of the type 2 diabetes prevention and control program requires effective measures, deep understanding of the problems and solving them.

Feeding in adults with type II diabetes mellitus in three public hospitals in Cundinamarca, Colombia

Introduction: Type II diabetes mellitus (DMII) is one of the main causes of morbidity and mortality both worldwide and in Colombia. It mainly affects men and women over 45 years of age. Inadequate control of this disease can generate greater health complications making it one of the most costly diseases in the country. Treatment includes activities other than glycemic control and requires constant monitoring by medical personnel and educational processes directed at the patient and his or her family. Objective: To characterize the feeding of patients with DMII in three public hospitals of Cundinamarca. Materials and methods: We conducted a cross-sectional descriptive study of 212 patients that analyzed sociodemographic characteristics, frequency of consumption and feeding practices. Results: Most of the population was over 45 years old and had a low educational level. In total, 52% had a dietary plan, but only 8.9% received nutritional guidance from a nutritionist. The consumption of carbohydrates predominated, with low consumption of proteins, vitamins, minerals, and fiber. The consumption of sugars was lower in patients with a dietary plan (p <0.05). Conclusions: Most of the patients did not have an adequate nutrition; moreover, there was low adherence to dietary treatment, weakness in nutritional counseling and barriers to food access. These results can contribute to improving policies for the prevention and control of DMII and strategies based on the sociocultural context of the patients.

Tackling the growing diabetes burden in Sub-Saharan Africa: a framework for enhancing outcomes in stroke patients

According to the World Health Organization (WHO), more than 80% of worldwide diabetes (DM)-related deaths presently occur in low- and middle-income countries (LMIC), and left unchecked these DM-related deaths will likely double over the next 20 years. Cardiovascular disease (CVD) is the most prevalent and detrimental complication of DM: doubling the risk of CVD events (including stroke) and accounting for up to 80% of DM-related deaths. Given the aforementioned, interventions targeted at reducing CVD risk among people with DM are integral to limiting DM-related morbidity and mortality in LMIC, a majority of which are located in Sub-Saharan Africa (SSA). However, SSA is contextually unique: socioeconomic obstacles, cultural barriers, under-diagnosis, uncoordinated care, and shortage of physicians currently limit the capacity of SSA countries to implement CVD prevention among people with DM in a timely and sustainable manner. This article proposes a theory-based framework for conceptualizing integrated protocol-driven risk factor patient self-management interventions that could be adopted or adapted in future studies among hospitalized stroke patients with DM encountered in SSA. These interventions include systematic health education at hospital discharge, use of post-discharge trained community lay navigators, implementation of nurse-led group clinics and administration of health technology (personalized phone text messaging and home tele-monitoring), all aimed at increasing patient self-efficacy and intrinsic motivation for sustained adherence to therapies proven to reduce CVD event risk.

Increasing physical activity in Belgian type 2 diabetes patients: a three-arm randomized controlled trial

BACKGROUND

Pedometer-based physical activity programs have been typically delivered in a group format by a behavioral expert. An alternative strategy that builds on existing interactions is delivery through individual consultation by a general practitioner (GP). These two delivery strategies have not been directly compared.

PURPOSE

To compare effectiveness of a 12-week physical activity (PA) intervention for type 2 diabetes patients delivered by a trained GP via an individual consultation or as group delivery by a behavioral expert.

METHOD

Sixty-seven primary care participants (mean age = 67.4 years, 70% male) from three Belgian general practices were randomized into three different treatment arms: (1) individual consultation (n = 22) with three PA contacts with the patient's GP; (2) group counseling (n = 21) with three PA group sessions delivered by a behavioral expert; and (3) a control arm (n = 24) receiving no intervention. Participant inclusion criteria were ≤80 years; 25-35 kg/m²; ≤12% HbA1c and reporting no PA limitations. Outcome measures were pedometer-determined steps/day, self-reported PA, and health parameters (weight, body mass index, waist circumference, total cholesterol, fasting glucose, and HbA1c).

RESULTS

Group counseling participants increased 1,706 steps/day over baseline significantly (p ≤ 0.05) more than other treatment arms. Moreover, they increased their self-reported PA (+82 min/day), while control arm participants showed a decrease in PA (p ≤ 0.05). Participants of the individual consultation had a decrease in waist circumference (-1.4 cm) and HbA1c (-0.32%) and a lower increase in total cholesterol (+7.2 mg/dl) compared to the other treatment arms (all p ≤ 0.05).

CONCLUSION

Group counseling in type 2 diabetes patients improved PA, whereas individual consultations had an impact on some health outcomes on the short-term.

Dose de insulina prescrita versus dose de insulina aspirada

OBJETIVOS: Comparar a dose aspirada de insulina na seringa à dosagem prescrita entre os usuários que a autoaplicam; relacionar as divergências às variáveis sociodemográficas e clínicas e identificar as dificuldades referidas no procedimento. MÉTODOS: Participaram do estudo 169 usuários acompanhados pela Estratégia Saúde da Família (ESF) de um município do Estado de Minas Gerais, entre agosto e outubro de 2006. RESULTADOS: Entre os usuários que aspiraram doses diferentes da prescrita (36,1%), 77% justificaram dificuldade para visualizar a escala graduada da seringa e 29,5%, dificuldades motoras para manusear precisamente a seringa. O sexo (feminino), a idade (>60 anos) e a escolaridade (< 8 anos de estudo) foram as preditoras estatisticamente significantes. CONCLUSÃO: Os dados mostram a necessidade de intervenções direcionadas ao desenvolvimento de habilidades para a autoaplicação da insulina, considerando as limitações/recursos de cada usuário. As propostas da ESF podem favorecer as ações para atenção à saúde centradas nas necessidades da clientela adscrita.

Fatores associados à auto-aplicação da insulina nos usuários com diabetes mellitus acompanhados pela Estratégia Saúde da Família

Estudo seccional que objetivou comparar dois grupos de usuários com diabetes mellitus acompanhados pela Estratégia Saúde da Família e distinguidos pela auto-aplicação ou não de insulina, em relação às variáveis sócio-demográficas, às dificuldades percebidas e ao responsável pela auto-aplicação. Participaram 269 usuários selecionados por meio de uma amostragem aleatória simples, em 37 unidades da Estratégia Saúde da Família, da área urbana de um município do Estado de Minas Gerais, Brasil. O grupo que faz auto-aplicação foi composto por 169 (62,8%) usuários e o que não faz, por 100 (37,2%). Ao comparar os grupos, a variável escolaridade foi estatisticamente significativa; 45% dos que não auto-aplicam a insulina referiram ausência de dificuldades físicas ou cognitivas que impedissem a realização deste procedimento, demonstrando potencial para a adesão; 90% referiram necessitar de auxílio em todo o processo de administração de insulina no domicílio e destes, 75% informaram receber auxílio da família. A Estratégia Saúde da Família favorece o desenvolvimento de intervenções centradas nas necessidades da clientela adscrita, estimulando-a para o autocuidado, e os resultados do presente estudo poderão contribuir com o planejamento destas intervenções.

Enhancing regular physical activity and relapse prevention through a 1-day therapeutic patient education workshop: A pilot study

OBJECTIVE

Physical activity (PA) is important for managing chronic diseases, such as diabetes and obesity. Yet over half of patients who adopt PA programs do not maintain them at 6 months. To encourage regular PA among our patients, we developed a 1-day outpatient motivational workshop based on well-known theoretical frameworks. The purpose of this pilot study was to evaluate the effectiveness of the motivational workshop in terms of total and activity-specific energy expenditures (EE) and body mass index (BMI).

METHODS

This workshop is an integrative model of multiple theoretical frameworks for therapeutic education and behavior change, alternating individual sessions and group sessions in a multidisciplinary setting. Patients completed a validated, self-administered, quantitative PA frequency questionnaire at baseline and at 1 year. Stages of change and relapse risk were identified at baseline.

RESULTS

Twenty-five subjects, mean age 48 years and BMI 34.1kg/m(2), completed pre-/post-evaluations. At baseline, 73% of subjects reported regular activities of daily living and 52% reported regular formal exercise. Using total and activity-specificEE, we identified 69.2% as sedentary. A relapse risk was recognized in 76%. Paired t-tests showed significant (P=0.048) reductions in weight and BMI and a significant (P=0.015) increase in high-intensity exerciseEE. Total EE showed no difference. Among baseline sedentary subjects, 39% became active.

CONCLUSION

This workshop may be effective in modifying PA patterns, thereby decreasing sedentarism and fostering PA maintenance.

PRACTICE IMPLICATIONS

The theory-based workshop for increasing motivation to maintain optimal PA behavior provides an example of translational intervention from theoretical models to clinical practice.

Exploring doctor-patient communication in immigrant Australians with type 2 diabetes: a qualitative study

OBJECTIVE

The study explored the perceptions of Australian immigrants about their interactions with doctors regarding the diagnosis, treatment, and management of type 2 diabetes mellitus.

RESEARCH DESIGN AND METHODS

In-depth interviews were conducted with 30 men and women from Greek, Indian, Chinese, and Pacific Island backgrounds living in Melbourne, Australia, to elicit their perceptions of the management of diabetes and its impact. Participants were recruited through a convenience sample of general practitioners and community organizations providing support to people living with diabetes. Topics discussed included initial reaction to diagnosis, patient-health care provider communication, and the influence of message framing on the perception of the quality of the doctor-patient relationship. Transcripts were coded and analyzed by both authors.

RESULTS

Numerous issues facilitate or inhibit constructive and positive relationships between doctors and patients with type 2 diabetes. Patients reported difficulty in absorbing all the information provided to them at early consultations, and experienced difficulty comprehending the practical aspects of management. Styles of communication and discourses of normalization and catastrophe influenced participants' responses.

CONCLUSION

Doctors face a complex task in encouraging behavioral change and adherence and establishing and maintaining a supportive relationship with patients. The timing and technical complexity of communication about diabetes, its management, and the prevention of complications require further attention.

Diabetes care in sub-Saharan Africa

The increasing numbers of people with type 2 diabetes is a worldwide concern. It presents an added challenge in sub-Saharan Africa, where diabetes must compete for resources with communicable diseases. A scarcity of financial resources and appropriate staff mean that many people with type 2 diabetes have complications and that those with type 1 diabetes have an extremely short life-expectancy, whether or not they have been diagnosed with the disorder. We review the current evidence on diabetes care in sub-Saharan Africa and propose an 11-point action plan to address this problem in the region.

Dietary behavior and type 2 diabetes care

OBJECTIVE

To explore risk factors modification, as well as barriers and facilitators for behavioral change in Mexican type 2 diabetics and their families.

METHODS

Risk assessment and impact evaluation included measurements on anthropometrics, diet, physical activity, nutrition knowledge, and HbA(1c.) The intervention included discussion groups and promoted behavioral change on dietary risk, physical exercise, and basic diabetic knowledge of 48 urban diabetic patients and 38 relatives. The educational method consisted of cognitive reframing and situational problem solving during five meetings over an 8-month period.

RESULTS

Diabetics were older and less educated than their participating relatives (55.8+/-11 and 34.7+/-13.7 years old, and 4.5+/-3.4 and 7.8+/-3.7 years of schooling, respectively). Factors such as diet, degree of obesity, physical activity and HbA(1c), reflected that 92% of diabetic patients and 83% of their relatives were at high health risk. After the intervention, nutritional knowledge and diet-health awareness increased (p=.013 and .001 respectively); however, no significant health-risks reduction was observed.

DISCUSSION

Focus group analysis suggested that lack of support from family and health services, low income, neighborhood insecurity and misleading "popular knowledge" and advice are key barriers to behavioral change.

PRACTICE IMPLICATIONS

The study supports the understanding of constrains to health promotion campaigns and better health provider-patient interactions in Mexican population. Additionally, the study contributes to the general knowledge of ethnic socio-cultural environment influences over health care issues, primarily to diet modifications.

The diabetes educator: trying hard, but must concentrate more on behaviour

Current guidelines state that education is fundamental to help people with diabetes modify their lifestyle and prevent ill health and early death. However, many people with diabetes are not receiving adequate education. There is a widespread assumption that transferring knowledge will improve health outcomes but there is little empirical support for this assertion. Indeed, knowledge and behaviour are poorly correlated. Knowledge may be a necessary condition but is rarely a sufficient condition for behaviour change. Single interventions, cognitive or behavioural, have had disappointing results, unsurprisingly given the complexity of human behaviour. The most effective interventions are multifaceted and include education, behavioural and psychosocial elements, and target lifestyle change and factors such as self-efficacy and empowerment. We advocate that educational interventions should have multiple components. They should aim to improve patients' sense of self-efficacy and empowerment, and build attitudes towards diabetes that will support the lifestyle changes needed for successful self-management. These conclusions have implications for future research and clinical practice.

Evaluation of the quality and contents of diabetes mellitus patient education on Internet

Patient education is widely regarded as an essential component of chronic disease care and effective health promotion. Internet is extremely useful medium in this respect. Web-based information is seldom the subject of systematic investigation for its accuracy and appropriateness for patients. Objective of this study was to evaluate of web-based diabetes patient education material for well-accepted evaluation criteria and core education concepts. Out of 214 web-sites retrieved from meta search engine, 53 sites themselves provide patient information and so considered for evaluation. Data obtained was analyzed by cluster analysis and classified into four categories with respect to quality. Considerable variability in quality of diabetes patient education web-sites was found with respect to core educational concepts and HSWG criteria. Inclusion of evidence-based medicine concepts, role of family support, enhancement in customized content and easier feedback mechanism in the web-sites can be a significant development in the direction of patient-centered diabetes care.

[Home glycemic profiles as an strategy for insulin therapy adjustments in patients with type 1 diabetes mellitus]

The goal of this paper is to characterize the glycemic profiles of patients with type 1 diabetes mellitus like a strategy in insulin adjustments. A total of 3259 tests were realized being 781 before breakfast, 752 before lunch, 765 before dinner and 740 before bed and 221 in the dawn. The average of the blood glucose tests in these periods overstepped the superior limits in 6.87%, 3.83%, 11.37%, 30.50% e 19.28% respectively. These data gave the conditions to make the insulin adjustments. The HbA1c levels evidenced that there was no significant statistical difference in the metabolic control, but they remained in 10%.

[Perspective of patients on type-2 diabetes and their relationship with primary care health professionals: a qualitative study]

AIM

The objective of this study is to investigate the perception that people with type 2 diabetes have about the disease and about their relationship with the primary healthcare professionals.

DESIGN

Qualitative research, carried out between September-November 2000.

SETTING

Primary healthcare center Barrio del Pilar from Madrid.

PARTICIPANTS

15 persons with type 2 diabetes. Variables considered to design the profiles of the interviewed were: age, gender, educational level, and time since diagnosis.

METHOD

Structural sampling and open interviews.

RESULTS

Patients express having scarce information regarding the consequences of diabetes. As diabetes is symptom free represents a difficulty for being perceived as a severe disease. The most valued aspects of the relationship with health professionals are that they provide with clear and tailored information, build a trust context, support changes and take account their perspectives and living circumstances.

CONCLUSIONS

It is essential to recognize how patients understand and shape the disease. Information provided by professionals have to be tailored to patients necessities, and take place in a trusting environment. Decisions related with diabetes management have to be aligned with patients perspectives. Effective communication could be considered as a useful tool to encourage adherence and improve healthcare quality.

National survey of pharmacist certified diabetes educators

We sought to determine the demographics of pharmacists who were certified diabetes educators (CDEs) and information about their training, professional affiliations, and types of diabetes education services that they provide. We also queried these pharmacists about clinical activities, reimbursement, impact of certification, and intent to pursue CDE recertification. A list of pharmacists who were CDEs as of August 31, 2000, was obtained from the National Certification Board for Diabetes Educators. We then sent a six-page anonymous survey to 415 pharmacist CDEs; 233 surveys (56.1%) were returned. Of these respondents, 140 are women and 93 are men, with a mean age of 41.5 years. Most reside in Southern or Western states. Average time since pharmacist licensure was 17 years, and average time as a CDE was 5 years. Most had completed postgraduate training, including residencies and/or fellowships; 52.8% had faculty appointments; 46.7% stated they were billing for their services; and 45.9% were obtaining reimbursement. Most pharmacists (84.4%) stated that they intended to pursue CDE recertification. Providing details about pharmacist CDEs and their clinical activities may motivate other pharmacists to pursue this credential. Pharmacists are often the most accessible of all health care providers, and earning the CDE credential may be an important contribution to diabetes care and education.

[Evaluation of 2 home monitoring schemes in patients with type 1 diabetes mellitus]

The goal of this study was to evaluate the effectiveness of two monitoring schemes(blood and urine) in the metabolic control of type 1 diabetic patients, in biweekly therapeutic adjustments, along 6 months of participation in the educational groups. A sample of 34 patients was divided in two groups. The interventions proposed to group A were daily blood glucose monitoring, during three consecutive days for each period (before breakfast, before lunch, before dinner and before bed) and biweekly in the dawn. For the other group B was proposed daily urine glucose monitoring, during three consecutive days for each period (before breakfast, before lunch, before dinner and before bed). These schemes were used to construct glycemic profile and to determine the therapeutic adjustments. The results evidenced that there was no significant statistical difference in the metabolic control after proposed intervention in each group. In spite of this, the monitoring facilitated the educational process and the considerations about the use of more intensive monitoring schemes.

Current perspectives of therapeutic patient education in Italy

Therapeutic patient education is a well-defined branch of health education aimed at patient empowerment. It consists of helping the patient to understand his own disease and its treatment, actively collaborating to its fulfillment and to take care of his own health status in order to maintain and improve his life quality. The correct implementation of both communication and therapeutic patient education involves the mastery of specific professional skills by healthcare personnel. In Italy, institutional therapeutic patient education is delivered mainly to diabetic patients. However, other activities and projects aimed at therapeutic education of chronic patients are gradually appearing. An overview of current situation and perspective of therapeutic patient education practice in Italy are presented.

A model educational program for people with type 2 diabetes: a cooperative Latin American implementation study (PEDNID-LA)

OBJECTIVE

To implement an educational program in 10 Latin American countries and to evaluate its effect on the clinical, biochemical, and therapeutic aspects as well as the economic cost of diabetes.

RESEARCH DESIGN AND METHODS

Educators from each participating country were previously trained to implement the educational model. The patient population included 446 individuals with type 2 diabetes; all patients were <65 years of age, did not require insulin for metabolic control, did not have severe complications of diabetes or life-limiting illnesses, and had not previously participated in diabetes education courses. Clinical and therapeutic data and the cost of their pharmacological treatment were collected 6 months before participation in the educational program (-6 months), on entry into the program (time 0), and at 4, 8, and 12 months after initiation of the program.

RESULTS

All parameters measured had improved significantly (P < 0.001) by 1 year: fasting blood glucose (mean +/- SD) 10.6 +/- 3.5 vs. 8.7 +/- 3.0 mmol/l; HbA(1c) 9.0 +/- 2.0 vs. 7.8 +/- 1.6%; body weight 84.6 +/- 14.7 vs. 81.2 +/- 15.2 kg; systolic blood pressure 149.6 +/- 33.6 vs. 142.9 +/- 18.8 mmHg; total cholesterol 6.1 +/- 1.1 vs. 5.4 +/- 1.0 mmol/l; and triglycerides 2.7 +/- 1.8 vs. 2.1 +/- 1.2 mmol/l. At 12 months, the decrease in pharmacotherapy required for control of diabetes, hypertension, and hyperlipidemia represented a 62% decrease in the annual cost of treatment ($107,939.99 vs. $41,106.30 [U.S.]). After deducting the additional cost of glucosuria monitoring ($30,604), there was still a 34% annual savings.

CONCLUSIONS

The beneficial results of this educational model, implemented in 10 Latin American countries, reinforce the value of patient education as an essential part of diabetes care. They also suggest that an educational approach promoting healthy lifestyle habits and patient empowerment is an effective strategy with the potential to decrease the development of complications related to diabetes as well as the socioeconomic costs of the disease.

A taxonomy for diabetes educational interventions

Diabetes education is a cornerstone of diabetes self-care management. Despite terrific progress in refining educational interventions, the diabetes literature continues to contain substantial inconsistencies in reporting the elements of educational interventions. This unnecessary variation in the quality of reporting has led to difficulties in understanding the results of educational research in diabetes. We provide a taxonomy that should prove helpful, both in the conceptual design of diabetes educational interventions and in the reporting of those interventions. An application of this taxonomy to 30 diabetes educational randomized controlled trials is presented to highlight the extent of variation in diabetes educational interventions.

Women living with type II diabetes: the intrusion of illness

This study is part of a larger research project which aimed to create an understanding of how people with type II diabetes incorporated chronic illness into their lives. We aimed to find wellness in the context of a chronic illness. The participatory action-orientated research (PAR) approach is consumer based and managed, and six women with diabetes and the research team met for eight two-hour sessions in August and September 1998. The objectives were to contribute to understanding of the health of adults who live with chronic illness by providing greater insight and understanding into the worlds of people who live with a chronic illness and allowing the voices of people with diabetes to be clearly heard in relation to their health. There was a wellness theme around taking time out, but considering the other dominant negative experiences, this study can only be considered as an attempt to find wellness in the context of chronic illness. The PAR process, built upon sharing, listening and reconstructing stories, worked toward the women being heard and having a voice for the first time. Listening and acting upon the voices of the women has implications for the practice of health care professionals.

Study circles at the pharmacy--a new model for diabetes education in groups

During the past years diabetes education has developed greatly. However, a survey of diabetes care in Sweden in 1995 showed that only 40% of the patients examined had acceptable HbAlc values. This underlines the need for an effective and low-cost patient education programme. In this study we tested the feasibility of a 1-year group education model for patients with type 2 diabetes at Swedish pharmacies. In the study circles, led by specially trained pharmacists, participants learned how to self-monitor glucose, to interpret the results and to act upon them. We conclude that study circles held at pharmacies are a feasible way of educating persons with type 2 diabetes. The group setting promoted learning through peer help and gave emotional support to participants. Metabolic control as measured by HbAlc improved significantly after 6 months, but reverted to baseline levels again at 12 months. The reason for this needs further investigation.

A survey of elderly diabetic patients attending a community clinic in Hong Kong

A cross-sectional survey was conducted on Chinese diabetic patients attending a community clinic in Hong Kong. A questionnaire, physical examination and blood tests were administered. Of 155 adults with diabetes mellitus recruited, the mean age was 63 years (SD 10.3), 77.4% were female and 41.9% illiterate. Half the patients achieved adequate knowledge scores. Knowledge was found to be associated with education level (OR 4.3, 95% CI 1.8, 10.0), longer disease duration (OR 3.2, 95% CI 1.4, 7.4) and complications (OR 0.3, 95% CI 0.1, 0.8). No correlation was found between knowledge and attitude or practice. Attitude was found to be associated with practice (OR 1.2, 95% CI 1.0, 1.3) and male gender (OR 2.9, 95% CI 1.1, 7.5); practice was associated with hypertension (0.5, 95% CI 0.2, 0.9). Older less educated Chinese diabetic patients can be educated about diabetes management, but knowledge does not always translate into practice.

Patient information systems that tailor to the individual

The potential of computers in patient education has been well described by Skinner et al. One of their recommendations was for more personalized systems. In this article we discuss how computer-based patient information systems can provide material that is tailored to the individual, giving a number of examples of systems developed in Scotland. We review some of the techniques used in developing tailored systems, and consider the evidence to date as to their efficacy.
