Factors affecting the use of dietetic services by patients with diabetes mellitus

Determinants of healthful eating and physical activity among adolescents and young adults with type 1 diabetes in Qatar: A qualitative study

BACKGROUND

In Qatar, as in the rest of the world, the sharp rise in the prevalence of type 1 diabetes (T1D) is a leading cause for concern, in terms associated with morbidity, mortality, and increasing health costs. Besides adhering to medication, the outcome of diabetes management is also dependent on patient adherence to the variable self-care behaviors including healthful eating (HE) and physical activity (PA). Yet, dietary intake and PA in adolescents and young adults (AYAs) with T1D are known to fall short of recommended guidelines. The aim of this study was to develop an in-depth understanding of the behavioral determinants of HE and PA adherence among Arab AYAs within the age range of 17-24 years with T1D attending Hamad General Hospital.

METHODS

Semi-structured, face-to-face individual interviews were conducted with 20 participants. Interviews were based on an integrative health behavior change model, the I-Change model (ICM). All interviews were audio-recorded, transcribed verbatim, and analyzed using the framework method.

RESULTS

More participants reported non-adherence than adherence. Several motivational determinants of adherence to HE and PA were identified. The majority of participants were cognizant of their own behaviors towards HE and PA. Yet, some did not link low adherence to HE and PA with increased risks of health problems resulting from T1D. Facilitators to adherence were identified as being convinced of the advantages of HE and PA, having support and high self-efficacy, a high level of intention, and a good health care system.

CONCLUSION

The suboptimal adherence in AYAs to HE and PA needs more attention. Supportive actions are needed to encourage adherence to a healthy lifestyle to achieve benefits in terms of glycemic control and overall health outcomes, with a special focus on adolescents. Interventions are needed to foster motivation by addressing the relevant determinants in order to promote adherence to these two behaviors in AYAs with T1D.

Factors associated with the number of consultations per dietetic treatment: an observational study

Background

Greater understanding of the variance in the number of consultations per dietetic treatment will increase the transparency of dietetic healthcare. Substantial inter-practitioner variation may suggest a potential to increase efficiency and improve quality. It is not known whether inter-practitioner variation also exists in the field of dietetics. Therefore, the aims of this study are to examine inter-practitioner variation in the number of consultations per treatment and the case-mix factors that explain this variation.

Methods

For this observational study, data were used from the National Information Service for Allied Health Care (LiPZ). LiPZ is a Dutch registration network of allied health care professionals, including dietitians working in primary healthcare. Data were used from 6,496 patients who underwent dietetic treatment between 2006 and 2009, treated by 27 dietitians working in solo practices located throughout the Netherlands. Data collection was based on the long-term computerized registration of healthcare-related information on patients, reimbursement, treatment and health problems, using a regular software program for reimbursement. Poisson multilevel regression analyses were used to model the number of consultations and to account for the clustered structure of the data.

Results

After adjusting for case-mix, seven percent of the total variation in consultation sessions was due to dietitians. The mean number of consultations per treatment was 4.9 and ranged from 2.3–10.1 between dietitians. Demographic characteristics, patients’ initiative and patients’ health problems explained 28% of the inter-practitioner variation. Certain groups of patients used significantly more dietetic healthcare compared to others, i.e. older patients, females, the native Dutch, patients with a history of dietetic healthcare, patients who started the treatment on their own initiative, patients with multiple diagnoses, overweight, or binge eating disorder.

Conclusions

Considerable variation in number of consultations per dietetic treatment is due to dietitians. Some of this inter-practitioner variation was reduced after adjusting for case-mix. Further research is necessary to study the relation between inter-practitioner variation and the effectiveness and quality of dietetic treatment.

[Frequency of attendance and degree of control of type-2 diabetic patients]

OBJECTIVE

To analyse whether the number of doctor's appointments for type-2 diabetes patients is linked to the degree of control of his/her illness.

SETTING

Primary care. Two teaching health centres in the public network (Petrer 1 and Petrer 2, Alicante, Spain).

DESIGN

Retrospective, observational study. Review of computerised clinical histories and direct interview with patients. Patients with DM2 included in Diabetes Programme (DP); 18-month follow-up (January 2003-June 2004).

SAMPLE SIZE

86 patients (mean, 15 visits/year; SD, 7.1; alpha, 0.02; and accuracy to 2%). RANDOMISED SAMPLING: Study factor was number of visits. Evaluation criterion was difference in glycosylated haemoglobin (A(1c)) between start and end. Characteristics of the patients, characteristics of the illness and numbers of changes in treatment done were analysed. Statistical tests were: chi(2), Student t test, confidence intervals, and multivariate analysis.

RESULTS

Mean age was 65.5 (95% CI, 63.5-67.5); women, 57%; years of disease's evolution, 7.07 (95% CI, 5.6-8.5). Treatment was: diet, 12.8%; ADOs, 61.6%; ADO+insulin, 17.4%; insulin, 8.1%. Number of visits to the HC: total, 28.8 (95% CI, 26.5-31.2); medical, DP 4.7 (95% CI, 4.1-5.2); nursing DP, 11 (95% CI, 9.9-12.1). Changes of treatment were 1.73 (95% CI, 1.3-2.1); initial A1C, 7.0 (95% CI, 6.6-7.3), and final A1C, 6.9 (95% CI, 6.7-7.1). On multivariate analysis, the number of changes in the treatment (beta=-0.430; P=.007) had 0an association, but the number of visits (beta=-0.273; P=.215) and the other variables analysed had no statistical association.

CONCLUSIONS

Improvement in control of glycosylated haemoglobin was not related to the number of visits to the doctor, but was related to changes in treatment.

The evolution of the nutritional management of diabetes

Diet and lifestyle advice for individuals with diabetes has changed dramatically. The changes in nutritional recommendations have largely been in response to advances in the knowledge of the biochemical and physiological mechanisms of impaired glucose metabolism and the micro- and macrovascular complications of diabetes. The most recent guidelines for the nutritional management of diabetes were set out by Diabetes UK in 2003. This consensus-based advice paper builds on the previous evidence-based review papers of the European Association for the Study of Diabetes in 2000 and the American Diabetes Association in 2002. The changes from previous recommendations include a more liberal use of sucrose, in line with healthy eating recommendations for the general population, and allow for greater flexibility in energy derived from carbohydrate and monounsaturated fat. In addition, monounsaturated fats are promoted as the fat of choice and active promotion of carbohydrate foods with a low glycaemic index is encouraged. These guidelines emphasise the practical application of nutritional management of diabetes and the need to provide education and support in a structured way that will facilitate change in diet and lifestyle behaviour. Structured educational programmes have been shown to be effective in reducing the progression to diabetes and also in slowing the onset and progression of the complications of diabetes. These programmes require ongoing intensive input to maintain behavioural change in diet and lifestyle. Considerable energy and resources are required to set up and maintain these educational programmes, but the cost per individual is small compared with the costs of treating the complications of diabetes.

The implementation of nutritional advice for people with diabetes

These consensus-based recommendations emphasize the practical implementation of nutritional advice for people with diabetes, and describe the provision of services required to provide the information. Important changes from previous recommendations include greater flexibility in the proportions of energy derived from carbohydrate and monounsaturated fat, further liberalization in the consumption of sucrose, more active promotion of foods with a low glycaemic index, and greater emphasis on the provision of nutritional advice in the context of wider lifestyle changes, particularly physical activity. Monounsaturated fats are now promoted as the main source of dietary fat because of their lower susceptibility to lipid peroxidation and consequent lower atherogenic potential. Consumption of sucrose for patients who are not overweight can be increased up to 10% of daily energy provided that this is eaten in the context of a healthy diet and distributed throughout the day [corrected]. Evidence is presented for the effectiveness of advice provided by trained dieticians. The increasing evidence for the importance of good metabolic control and the growing requirement for measures to prevent Type 2 diabetes in an increasingly obese population will require major expansion of dietetic services if the standards in National Service Frameworks are to be successfully implemented.

Health care use by diabetic patients in the Netherlands: patterns and predicting factors

AIMS

Diabetic patients require care from a variety of health care providers, but little is known about their actual use of health care. Aims of this study were to (1) obtain information on health care use by diabetic patients in the Netherlands, (2) distinguish patterns of health care utilisation among these patients, and (3) develop insight into the factors predicting these patterns.

METHOD

Data on 388 diabetic patients were extracted from a nationally representative database of patients with chronic disease. Data on health care utilisation and background variables were collected in 1998 by means of a survey. Patients' GPs registered information about medical diagnosis, illness duration and co-morbidity. Analysis included descriptive statistics, as well as cluster and logistic analysis.

RESULTS

Diabetic patients use a wide range of services, but large differences exist. Four patterns of health care utilisation could be distinguished: a pattern of low consumption, one of moderate consumption with a central role for internal medicine, one of more extensive diabetes care consumption, and one of high medical and home care consumption. Type 1 diabetes appeared to be an important determinant of the moderate, mainly internal medicine pattern and the more extensive diabetes care pattern. The pattern of high medical and home care was not predicted by diabetes type, but by the presence of co-morbidity and by poor self-rated health.

CONCLUSION

Despite the fact that diabetic patients use a wide range of health care services, there seems to be a problem of under utilisation, especially among type 2 diabetic patients.
