Abstract
Periodontitis has been considered the sixth complication of diabetes. The aim of this study was to assess the impact of periodontal treatment on diabetes-related healthcare costs in patients with diabetes. Data on 41,598 adults (45.7% female) with at least 1 insurance claim in 2012 for diabetes-related treatment were included in the analysis. The impact of periodontal treatment on diabetes-related healthcare costs was analysed by means of fixed effect models for panel data. The median diabetes-related healthcare costs per patient in 2012, including costs for diagnosis, treatment, medication, and hospitalisation, were €38.45 per quarter (interquartile range €11.52 - €263.14). The fixed effects models showed a reduced expenditure on diabetes-related costs of €12.03 [95%CI €-15.77; €-8.29] per quarter following periodontal treatment. These results support the relevance and necessity of good periodontal care for patients with diabetes.
Highlights
Periodontitis has been considered a sixth complication of diabetes
The findings indicate that more advanced periodontitis treatment may result in higher benefits, the benefits are mainly attributable to non-m edication-related healthcare costs, and that different patient groups may benefit differently from periodontal treatment
The findings presented in this study are in line with two previous claims data studies showing reductions in healthcare costs for patients with diabetes after receiving periodontal treatment,[15 16] our results show smaller reductions
Summary
The aim of this study was to assess the impact of periodontal treatment on diabetes- related healthcare costs in patients with diabetes. Individuals with at least one diabetes-related treatment claim in 2012 were included for analysis. A series of panel data regression models with patient-level fixed effects were estimated to assess the impact of periodontal treatment on diabetes-related healthcare costs. The median diabetes-related healthcare costs per patient in 2012 were €38.45 per quarter (IQR €11.52–€263.14), including diagnoses, treatment, medication and hospitalization costs. The fixed effect models showed €12.03 (95% CI −€15.77 to −€8.29) lower diabetes-related healthcare costs per quarter of a year following periodontal treatment compared with no periodontal treatment. Individuals with diabetes who suffer from periodontitis, exhibit more difficulties to stabilize metabolic control, and they develop other diabetes complications more frequently.[1] Partly because of this, it was previously suggested to Significance of this study
