Reliability of BOAS and OHAT.

Purpose
To identify the scale that is more suitable for oral health assessment in stroke patient population with indwelling gastric tubes.
Methods
A total of 198 patients with indent gastric tubes were selected from 1250 stroke patients to evaluate their oral health using both the BOAS and the OHAT scales. The scores obtained from both scales were then compared to evaluate the feasibility, reliability, and validity of each scale in assessing oral health among stroke patients with indwelling gastric tubes.
Results
The results showed that both the BOAS and OHAT scales exhibited good reliability and validity in stroke patients with indwelling gastric tubes. The Cronbach’s alpha coefficients of BOAS and OHAT in stroke patients with indwelling gastric tubes were 0.89 and 0.91, respectively. In the exploratory factor analysis, one and two common factors were extracted from the two scales, with cumulative variance contributions of 65.89% and 71.85%, respectively. In addition, potential influencing factor correlation analysis found that gender and marital status had a significant correlation with the BOAS score(P < 0.05), the Activities of daily living (ADL) score was found to be significantly correlated with the OHAT score (P < 0.05). Drinking, smoking, income, consciousness, and the result of the water swallow test were all correlated with BOAS and OHAT scores(P < 0.01).
Conclusions
The BOAS and OHAT have demonstrated good reliability and validity and in their ability to assess the oral health of stroke patients with indwelling gastric tubes. Therefore, it is recommended that the selection of oral assessment scales should be further refined in different disease stages of stroke patients to assess the oral health status of patients more accurately and personalized.

研究目的：筛选更适用于留置胃管脑卒中患者口腔健康评估的量表。
研究方法：本研究从1250名脑卒中患者中纳入198名留置胃管患者，分别采用口腔健康评估量表（BOAS）与口腔健康评估工具（OHAT）对其口腔健康状况进行评估。随后对两种量表所得评分进行比较，以评估二者在留置胃管脑卒中患者口腔健康评估中的可行性、信度与效度。
研究结果：结果显示，BOAS与OHAT量表在留置胃管脑卒中患者中均表现出良好的信度与效度。二者在该人群中的克朗巴赫α系数分别为0.89与0.91。探索性因子分析结果表明，两种量表分别提取出1个和2个公因子，累积方差贡献率分别为65.89%与71.85%。此外，潜在影响因素相关性分析显示，性别与婚姻状况与BOAS评分呈显著相关（P<0.05）；日常生活活动能力（Activities of Daily Living, ADL）评分与OHAT评分呈显著相关（P<0.05）。饮酒、吸烟、收入水平、意识状态及饮水试验结果均与BOAS、OHAT评分呈显著相关（P<0.01）。
研究结论：BOAS与OHAT量表在留置胃管脑卒中患者的口腔健康评估中均展现出良好的信度与效度。因此，建议针对脑卒中患者的不同疾病阶段进一步细化口腔评估量表的选择，以更精准、更具个性化地评估患者口腔健康状况。
