Objective – To determine if glycemic control is improving in diabetic children in Wales; to identify factors associated with improvement.
Research design and methods– Data collected in 2001 and 2006.
Results – Over time HbA1c reduced from 9.08±1.66 to 8.88±1.63% (p=0.012). There were differences between centers (p<0.001) and differential change over time (interaction p<0.001). Since 2001 five centres had appointed a pediatric diabetes specialist nurse (PDSN). These centres improved HbA1c from 9.59±1.88 to 8.72±1.61% (p<0.001). Glycemic control was worse in children aged >10y compared to younger patients (p<0.001). Improvement occurred in those aged >10y. Age (p=0.003) and insulin dose (p<0.001) were positively and independently associated with HbA1c. Thus any influence of PDSNs was not achieved through increased insulin prescription.
Conclusions – Improvement in glycemic control has occurred. Worse control is seen associated with greater prescribed insulin dose in older children. Appointing PDSNs was associated with improved glycemic control amongst adolescents.
