Fatigue is common among medical professionals and has been linked to poor performance and medical error. Objective. To characterize sleep quality and its association with severe fatigue in emergency medical services (EMS) providers.
We studied a convenience sample of EMS providers who completed three surveys: the Pittsburgh Sleep Quality Index (PSQI), the Chalder Fatigue Questionnaire (CFQ), and a demographic survey. We used established measures to examine survey psychometrics and performed t-tests, analysis of variance (ANOVA), and chi-square tests to identify differences in PSQI and CFQ scores.
One hundred nineteen surveys were completed. The eight-hour shift was most commonly reported (35.4%). A majority of subjects were overweight (41.9%) or obese (42.7%), and 59.6% had been diagnosed with one or more health conditions (e.g., diabetes). Results from psychometric tests were positive. The mean (+/- standard deviation) PSQI score was 9.2 (+/- 3.7). A CFQ score > or =4, indicating severe mental and physical fatigue, was present in 44.5% of the subjects. The mean PSQI score was higher among those reporting severe fatigue (11.3 +/- 3.2) than among those not reporting fatigue (7.5 +/- 3.0, p < 0.0001).
The results from this study suggest that the sleep quality and fatigue status of EMS workers are at unhealthy levels. The health and safety of the EMS worker and patient population should be considered in light of these results.
疲劳在医疗专业人员中很常见，与表现不佳和医疗错误有关。目的。描述睡眠质量及其与紧急医疗服务（EMS）提供者严重疲劳的关系。
我们研究了一个方便的 EMS 提供者样本，他们完成了三项调查：匹兹堡睡眠质量指数（PSQI），查德尔疲劳问卷（CFQ）和人口统计调查。我们使用既定的措施来检查调查的心理测量学，并进行 t 检验，方差分析（ANOVA）和卡方检验，以确定 PSQI 和 CFQ 分数的差异。
完成了 119 项调查。最常见的报告是八小时轮班（35.4％）。大多数受试者超重（41.9％）或肥胖（42.7％），59.6％被诊断出患有一种或多种健康状况（例如糖尿病）。心理测量学测试的结果是积极的。 PSQI 得分的平均值（+/-标准偏差）为 9.2（+/-3.7）。 CFQ 得分> = 4，表明严重的精神和身体疲劳，在 44.5％的受试者中存在。报告严重疲劳的受试者的平均 PSQI 评分（11.3 +/- 3.2）高于未报告疲劳的受试者（7.5 +/- 3.0，p <0.0001）。
这项研究的结果表明，EMS 工人的睡眠质量和疲劳状况处于不健康水平。应该根据这些结果考虑 EMS 工人和患者人群的健康和安全。
