現在、口腔癌患者の術後口腔機能障害を主観的に評価する尺度は存在しない。本研究の目的は、我々が開発した「術後口腔機能障害尺度(POD-10)」の信頼性と妥当性を評価することである。2019年9月から2021年8月の間に、対象となる口腔癌患者62名(年齢中央値72歳、男性42名、女性20名)を登録した。尺度の内的一貫性を示すクロンバックのα係数は0.94、再現性を示すクラス内相関係数は0.85(95%信頼区間:0.40-0.96、<0.05)であった。同時検証では、POD-10とEating Assessment Tool(EAT-10)の間に統計的に有意な相関が見られた(r = 0.89, < 0.05)。判別妥当性のテストでは、早期がん(ステージIとII)と進行がん(ステージIIIとIV)の間で統計的に有意な差が認められた(< 0.05)。POD-10のカットオフ値を算出するために、受信者動作特性分析を用いて24点を算出した。POD-10 は,口腔癌患者の術後口腔機能障害を主観的に評価できる臨床的に信頼性の高い妥当な尺度であることが示され,簡易診断ツールとしての利用が期待された.
Currently, there is no scale to subjectively assess postoperative oral dysfunction in patients with oral cancer. The purpose of this study was to evaluate the reliability and validity of the Postoperative Oral Dysfunction Scale (POD-10) that we developed. Between September 2019 and August 2021, 62 eligible oral cancer patients (median age, 72 years; 42 men and 20 women) were enrolled in the study. The Cronbach's alpha coefficient, which indicates the internal consistency of the scale, was 0.94, and the intraclass correlation coefficient, which indicates reproducibility, was 0.85 (95% confidential interval: 0.40-0.96, < 0.05). Concurrent validity testing showed a statistically significant correlation between POD-10 and Eating Assessment Tool (EAT-10) (r = 0.89, < 0.05). To test discriminant validity, statistically significant differences were found between early-stage cancer (stage I and II) and advanced-stage cancer (stage III and IV) ( < 0.05). Twenty-four points were calculated as the cutoff value for POD-10 using receiver operating characteristic analysis to calculate the cutoff value. The POD-10 was shown to be a clinically reliable and valid scale that can be used to subjectively assess postoperative oral dysfunction in patients with oral cancer and is expected to be used as a simple diagnostic tool.
