Dental claims data have been used for epidemiological studies without establishing the validity of the recorded diagnoses or procedures. The present study aimed to examine the accuracy of diagnoses, procedures, operation time, and the number of teeth recorded in dental claims data.
We reviewed the charts of 200 patients who visited and 100 patients who were hospitalized in the Department of General Dentistry, Orthodontics, and Oral and Maxillofacial Surgery in an academic hospital between August 2012 and December 2017. The sensitivity and specificity of the dental claims data for five diseases and 15 procedures were evaluated. We assessed the difference in the number of teeth and duration of general anesthesia between claims data and chart reviews.
Sensitivity was more than 86% for six out of seven diagnoses except for pericoronitis (67%). Specificity ranged from 72% (periodontal disease) to 100% (oral cancer for inpatient). The sensitivity of procedures ranged from 10% (scaling for inpatient) to 100%, and the specificity ranged from 6% (food intake on the day of the surgery) to 100%. The mean (standard deviation [SD]) number of teeth in the chart review was 22.6 (6.8), and in the dental claims was 21.6 (8.6). The mean (SD) operation time was 171.2 (120.3) minutes, while the duration of general anesthesia was 270.9 (171.3) minutes.
The present study is the first study to validate dental claims data, and indicates the extent of usefulness of each diagnosis and procedure for future dental research using administrative data.
牙科学索赔数据已被用于流行病学研究，但并未确定记录诊断或治疗的准确性。本研究旨在检查牙科学索赔数据中记录的诊断、程序、手术时间和牙齿数量的准确性。
我们回顾了 2012 年 8 月至 2017 年 12 月期间在一家学术医院的普通牙科、正畸科和口腔颌面外科就诊的 200 名患者和住院的 100 名患者的病历。评估了牙科学索赔数据对五种疾病和 15 种治疗方法的敏感性和特异性。我们评估了索赔数据和病历记录之间牙齿数量和全身麻醉持续时间的差异。
除了冠周炎（67%）外，七种诊断中有六种的敏感性超过 86%。特异性范围从牙周病的 72%到口腔癌的 100%（住院）。治疗方法的敏感性范围从住院病人的洁牙（10%）到 100%，特异性范围从手术当天的进食（6%）到 100%。病历记录中牙齿的平均（标准偏差[SD]）数量为 22.6（6.8），而在牙科学索赔中为 21.6（8.6）。平均（SD）手术时间为 171.2（120.3）分钟，全身麻醉持续时间为 270.9（171.3）分钟。
本研究首次验证了牙科学索赔数据，并指出了使用管理数据进行未来牙科学研究时每个诊断和治疗的有用程度。
