AIMS AND METHOD
We aimed to determine the prevalence of risk factors for obstructive sleep apnoea (OSA) in patients with mild cognitive impairment (MCI) or dementia. Using patient records across a 5 year period, we identified 16 855 patients with dementia or MCI. We gave scores for keywords relating to each modified STOP BANG parameter in patient progress notes. Based on individual scores, we stratified the population into groups with low, intermediate and high risk of OSA.
RESULTS
Our population had a high prevalence of risk factors and consequently high risk scores for OSA (18.21% high risk). Parameters directly related to sleep had a low prevalence.
CLINICAL IMPLICATIONS
The risk of developing or having OSA is high among patients with MCI and dementia. Low sleep parameter frequency probably suggests poor documentation of sleep rather than true prevalence. Our findings support the implementation of the STOP BANG or a similar screening tool as a standardised method to identify OSA risk in memory clinics.
目的与方法
我们旨在确定轻度认知障碍（MCI）或痴呆患者中阻塞性睡眠呼吸暂停（OSA）危险因素的患病率。通过对5年期间的患者记录进行分析，我们识别出16855例患有痴呆或MCI的患者。我们根据患者病程记录中与每个改良版STOP BANG参数相关的关键词进行评分。基于个体评分，我们将人群分为OSA低风险、中风险和高风险组。
结果
我们的研究人群中危险因素的患病率较高，因此OSA的风险评分也较高（18.21%为高风险）。与睡眠直接相关的参数患病率较低。
临床意义
MCI和痴呆患者发生或患有OSA的风险较高。睡眠参数出现频率较低可能表明睡眠记录不佳，而非真实患病率如此。我们的研究结果支持采用STOP BANG或类似的筛查工具作为记忆门诊识别OSA风险的标准化方法。
