Diabetes knowledge in adolescents with type 1 diabetes and their parents and glycemic control.

OBJECTIVE: To evaluate diabetes knowledge and skills (DKS) in adolescents (>10 year) with type 1 diabetes (T1D) and their parents, and its effect on glycemic control. METHODS: A ready-to-use program and a standardized questionnaire comprising 50 true-false questions based on this program, were elaborated by a National Committee, to help dispensing education at diagnosis of T1D. The questionnaire was completed by 2933 T1D patients (49% girls, 51% boys; 14.1 ± 2.5 year), 2180 mothers and 798 fathers, in 115 pediatric centers. Associations between DKS score (number of correct answers), glycated hemoglobin (HbA1c) and sociofamilial characteristics were assessed. RESULTS: DKS score increased with age, and was higher in girls than in boys and in mothers than in fathers; it correlated strongly between adolescents and their own parents; it was higher when adolescents had previously participated in diabetes camp and when parents had higher academic levels. HbA1c decreased significantly with parents' higher DKS score and academic level, and when both parents lived together. Mean adolescent DKS score was significantly higher in patients with HbA1c below 8% or 8.5% than for patients with HbA1c above these thresholds. CONCLUSION: A large survey in T1D children and adolescents and their parents showed associations between DKS and glycemic control, and the major role of sociofamilial factors.

Insulin regimens, diabetes knowledge, quality of life, and HbA1c in children and adolescents with type 1 diabetes.

OBJECTIVES: To further describe the changes in insulin therapy regimens and hemoglobin A1c (HbA1c) in children and adolescents with type 1 diabetes, and their associations with diabetes knowledge and quality of life. RESEARCH DESIGN AND METHODS: The study included 4293 children and adolescents (12.9 ± 2.6 yr, diabetes >1 yr) attending AJD (Aide aux Jeunes Diabétiques) summer camps between 2009 and 2014. The distribution of insulin regimens and associations between HbA1c, therapeutic regimens, diabetes knowledge (AJD questionnaire), and Quality of Life (Ingersoll et Marrero, Hvidoere Study Group short version) were assessed. RESULTS: The percentage of youth treated with insulin pumps increased up to about 45%, basal bolus stabilized around 40%, and other regimens decreased majorly. HbA1c was higher with premixed insulins only regimens (9.05 ± 2.43%), but there was no difference between pump (8.12 ± 1.09%), basal bolus (8.32 ± 1.33%) and two to three injections (8.18 ± 1.28%). Mean HbA1c decreased by 0.014% per year. The percentage of HbA1c <7.5% increased by 1.5% per year, and the percentages of HbA1c >9% or >10% decreased by 4 and 5.5%, changes being greater with the pump. HbA1c was weakly associated with diabetes knowledge, and strongly with general health perception and perception about diabetes. CONCLUSION: The percentage of children and adolescents with the highest risk of complications decreased markedly. The distribution of HbA1c better depicts the glycemic control in a population than the mean or the percentage of patients reaching the target (7.5%). HbA1c was more strongly associated with general health perception than with therapeutic regimens and diabetes knowledge.

Changes in insulin therapy regimens over 10 yr in children and adolescents with type 1 diabetes attending diabetes camps.

OBJECTIVE: To describe the changes in insulin therapy regimens of children and adolescents with type 1 diabetes over 10 yr and their correlation with hemoglobin A1c (HbA1c). RESEARCH DESIGN AND METHODS: The study included 7206 children and adolescents (age 12.8 ± 2.7 yr, more than 1 yr of diabetes duration) admitted in summer camps between 1998 and 2007 (707-896/yr). Based on injection times (breakfast, lunch, afternoon, dinner, bedtime) and insulin types (short, long and premixed; human or analog), 786 different therapeutic combinations were classified in six main types of regimens. The distribution of the different regimens and their correlation with HbA1c were evaluated as a function of year and age. RESULTS: Over 10 yr, basal bolus increased from 13 to 52% and the pump from <1 to 13%, regimens with two to three injections per day decreased from 50 to 25%, those with only premixed insulins from 33 to 7%, and diverse regimens from 9 to 1%. HbA1c was significantly higher with premixed insulin only, but there were no differences between the other regimens throughout the follow-up. Mean yearly HbA1c (8.21-8.45%) did not show any significant decrease, but the percentage of patients with HbA1c > 9 and 10% decreased significantly, in those treated with two to three injections and the pump, not with basal bolus or premixed only regimens. CONCLUSION: A major trend in intensifying insulin treatment in children and adolescents with type 1 diabetes was accompanied by modest improvements in HbA1c. No insulin regimen has shown any better results, except over premixed insulins.

The general aim of the association Aide aux jeunes diabétiques (AID) (Help for young diabetics) is to help children and their families live as well as possible with the disease. This requires specific education which forms part of the overall therapy and which combines training, information and patient compliance. The AJD works on all three of these levels during the holidays it organises for young diabetics.

A novel method for measuring patients' adherence to insulin dosing guidelines: introducing indicators of adherence.

BACKGROUND: Diabetic type 1 patients are often advised to use dose adjustment guidelines to calculate their doses of insulin. Conventional methods of measuring patients' adherence are not applicable to these cases, because insulin doses are not determined in advance. We propose a method and a number of indicators to measure patients' conformance to these insulin dosing guidelines. METHODS: We used a database of logbooks of type 1 diabetic patients who participated in a summer camp. Patients used a guideline to calculate the doses of insulin lispro and glargine four times a day, and registered their injected doses in the database. We implemented the guideline in a computer system to calculate recommended doses. We then compared injected and recommended doses by using five indicators that we designed for this purpose: absolute agreement (AA): the two doses are the same; relative agreement (RA): there is a slight difference between them; extreme disagreement (ED): the administered and recommended doses are merely opposite; Under-treatment (UT) and over-treatment (OT): the injected dose is not enough or too high, respectively. We used weighted linear regression model to study the evolution of these indicators over time. RESULTS: We analyzed 1656 insulin doses injected by 28 patients during a three weeks camp. Overall indicator rates were AA = 45%, RA = 30%, ED = 2%, UT = 26% and OT = 30%. The highest rate of absolute agreement is obtained for insulin glargine (AA = 70%). One patient with alarming behavior (AA = 29%, RA = 24% and ED = 8%) was detected. The monitoring of these indicators over time revealed a crescendo curve of adherence rate which fitted well in a weighted linear model (slope = 0.85, significance = 0.002). This shows an improvement in the quality of therapeutic decision-making of patients during the camp. CONCLUSION: Our method allowed the measurement of patients' adherence to their insulin adjustment guidelines. The indicators that we introduced were capable of providing quantitative data on the quality of patients' decision-making for the studied population as a whole, for each individual patient, for all injections, and for each time of injection separately. They can be implemented in monitoring systems to detect non-adherent patients.
