Abstract

Objective

We analyzed the impact of geographic distance from the clinic on adherence to recommended clinic visits and diabetes control among patients with type 1 diabetes (T1D) seen in a pediatric endocrinology clinic serving a rural region in eastern North Carolina.

Methods

We retrospectively included patients with T1D age ≤20 years seen in our clinic during 2017. Outcomes were tracked until June 2018. Distance from the clinic was determined according to the zone improvement plan (ZIP) code of patient address. Visit adherence was defined based on the number of attended visits during the study period, aiming for 1 every 3 months. Glycated hemoglobin (HbA1c) was measured at the first and last visits during the review period

Results

The analysis included 368 patients, of whom 218 (59%) completed at least 1 visit every 3 months. The median HbA1c was 9.1 (interquartile range [IQR]: 8.0, 10.3) at the initial visit, and 9.3 (IQR: 8.0, 11.1) at the final visit. Median distance from the clinic was 56 km (IQR: 35, 86). On multivariable logistic regression, greater distance from the clinic was associated with lower odds of visit adherence (odds ratio per 10 km: 0.93; 95% confidence interval: 0.87, 0.99; p=0.030). Neither distance to the clinic nor clinic visit adherence were associated with HbA1c.

Conclusions

Patients living further away from the clinic were less likely to adhere to the recommended visit schedule, but distance was not correlated with HbA1c levels. Further work is needed to assist families living far from the clinic with adhering to recommended visits.
