There is sufficient scientific evidence for the bidirectional association between periodontal diseases and diabetes. In this context, we hypothesized that periodontal treatment leads to lower healthcare costs in newly diagnosed diabetes patients by promoting a milder disease course.
A total of 23,771 persons were investigated who were continuously insured by German health insurances between 2011 and 2016, 18 years or older, and newly diagnosed with diabetes in 2013. The study population was divided into a periodontal treatment and control group (no periodontal treatment). The average treatment effect of a periodontal treatment on various types of healthcare costs (inpatient, outpatient, drug costs) was analyzed by a doubly robust method.
Finally, 5.3% of the study population could be assigned to the treatment group. In newly diagnosed diabetes patients with periodontal treatment, a reduction in total healthcare costs (0.96, 95%CI 0.89; 1.04), inpatient costs (0.87, 95%CI 0.69; 1.08), diabetes-related drug costs (0.93, 95%CI 0.84; 1.03) and other drug costs (0.97, 95%CI 0.89; 1.05) could be shown compared to the control group.
This study provides evidence that periodontal treatment for diabetes patients reduces healthcare costs. Fewer diabetes-specific complications and hospitalizations are expected.
有充分的科学证据表明牙周病和糖尿病之间存在双向关联。在这种情况下，我们假设牙周治疗通过促进疾病的轻度发展，可降低新诊断为糖尿病患者的医疗保健成本。
共调查了 23771 名在 2011 年至 2016 年期间持续受德国健康保险承保、18 岁或以上且 2013 年新诊断患有糖尿病的人。研究人群分为牙周治疗组和对照组（未进行牙周治疗）。通过双重稳健方法分析牙周治疗对各种类型医疗保健成本（住院、门诊、药物成本）的平均治疗效果。
最终，5.3%的研究人群可被分配到治疗组。在接受牙周治疗的新诊断糖尿病患者中，与对照组相比，总医疗保健成本（0.96，95%CI 0.89；1.04）、住院费用（0.87，95%CI 0.69；1.08）、糖尿病相关药物成本（0.93，95%CI 0.84；1.03）和其他药物成本（0.97，95%CI 0.89；1.05）有所降低。
本研究提供了证据表明，对糖尿病患者进行牙周治疗可降低医疗保健成本。预计糖尿病特异性并发症和住院治疗的次数会减少。
