Fear of hyperglycemia in parents of children with type 1 diabetes mellitus - a multi-center multi-national study

OBJECTIVE

Study aims: (1) developing and validating a novel questionnaire for measuring fear of hyperglycemia among parents of children with type 1 diabetes (T1D) - the Hyperglycemia Fear Survey - Parent version (FoHyper-P); (2) investigating correlations between parental fear of hyperglycemia and objective measures of glycemic control.

RESEARCH DESIGN AND METHODS

A multi-center, multi-national study of 152 parents of children with T1D was conducted in three large diabetes clinics from Israel, Poland, and Greece. Inclusion criteria were parents of children aged 6-16 years, at least 6 months from diagnosis, at least 3 months of CGM use and parental involvement in care. Parents filled the FoHyper-P and the Hypoglycemia Fear Survey - Parent Version (HFS-P). Patient data were obtained via electronic medical records and informative questionnaires. Bonferroni correction was performed to counteract multiple comparisons.

RESULTS

Significant strong-moderate correlations were found between FoHyper-P and HFS-P including total questionnaires scoring (r=0.747, P_Bonf. <0.001), worries subscales (r=0.735, P_Bonf <0.001), and behavior subscales (r=0.532, P_Bonf <0.001). Using linear regression models we found a positive association between the worry subscale and HbA1C. Weak correlations (P<0.05, not significant after Bonferroni correction) were found between time in range, time above range and parental fear of hyperglycemia as well as between worry subscales and a higher HbA1C in the past year, percent of hyperglycemia and lower TIR.

CONCLUSIONS

The FoHyper-P is a novel, validated tool for assessing parental fear of hyperglycemia. Integrating it into clinical practice addresses an underestimated aspect of parental diabetes management, enabling better care for children with T1D.

Adjusting insulin doses in patients with type 1 diabetes who use insulin pump and continuous glucose monitoring: Variations among countries and physicians

AIMS

To evaluate physicians' adjustments of insulin pump settings based on continuous glucose monitoring (CGM) for patients with type 1 diabetes and to compare these to automated insulin dose adjustments.

METHODS

A total of 26 physicians from 16 centres in Europe, Israel and South America participated in the study. All were asked to adjust insulin dosing based on insulin pump, CGM and glucometer downloads of 15 patients (mean age 16.2 ± 4.3 years, six female, mean glycated haemoglobin 8.3 ± 0.9% [66.8 ± 7.3 mmol/mol]) gathered over a 3-week period. Recommendations were compared for the relative changes in the basal, carbohydrate to insulin ratio (CR) and correction factor (CF) plans among physicians and among centres and also between the physicians and an automated algorithm, the Advisor Pro (DreaMed Diabetes Ltd, Petah Tikva, Israel). Study endpoints were the percentage of comparison points for which there was full agreement on the trend of insulin dose adjustments (same trend), partial agreement (increase/decrease vs no change) and full disagreement (opposite trend).

RESULTS

The percentages for full agreement between physicians on the trend of insulin adjustments of the basal, CR and CF plans were 41 ± 9%, 45 ± 11% and 45.5 ± 13%, and for complete disagreement they were 12 ± 7%, 9.5 ± 7% and 10 ± 8%, respectively. Significantly similar results were found between the physicians and the automated algorithm. The algorithm magnitude of insulin dose change was at least equal to or less than that proposed by the physicians.

CONCLUSIONS

Physicians provide different insulin dose recommendations based on the same datasets. The automated advice of the Advisor Pro did not differ significantly from the advice given by the physicians in the direction or magnitude of the insulin dosing.
