為了病患安全，醫療從業人員睡眠品質及其影響因素值得關心。本研究目的在探討影響醫療機構從業人員的睡眠品質因素，並比較醫療機構從業人員間的睡眠品質。研究方法以結構式問卷「匹茲堡睡眠品質量表(PSQI)」調查中部某醫療機構從業人員（分為醫療組、護理組及行政組）之睡眠品質。共發出200份問卷，扣除問卷不完整的份數，有效問卷共179份，回收率93.7%。研究結果顯示三組人員睡眠品質均為「差」（PSQI>5分），以ANOVA檢測三組睡眠品質得分差異，結果有顯著差異(p<.05)，以薛費氏事後比較發現護理組得分最高，表示護理人員睡眠品質最差。影響睡眠總分的因素主要為教育程度；影響睡眠潛伏期的因素為性別、教育程度、婚姻狀況、子女數及宗教信仰；和睡眠困擾有關的因素為性別、教育程度及輪班；影響日間活動功能不佳的因素為子女數；影響服用安眠藥物的因素為教育程度、婚姻狀況；和睡眠效率有關的因素為性別。於臨床實務之應用：研究結果可以提供醫療機構從業人員了解其影響睡眠品質的因素，同時也建議醫院主管應重視員工的睡眠品質，才能給病患優良的醫療照護。

The purpose of this study was to explore the sleep quality and its influencing factors among different medical staffs in a hospital. The Pittsburgh Sleep Quality Index (PSQI) was applied to represent the sleep quality of each individual. 200 questionnaires were sent out, and the retrieval rate was 93.7%. We found that the majority of medical staffs had poor sleep quality. The result of ANOVA showed that there was significant difference among the three groups with nurses reporting having the worst sleep quality. The influencing factors for sleep latency were sex, education, marital status, number of children, and belief. The influencing factors for daytime dysfunction was number of children; for use of sleeping medication were education and marital status; for habitual sleep efficiency was gender. The results of this study will enable the medical staffs to understand the influencing factors of sleep quality, and suggestion must be made to the hospital chiefs to attach importance of the sleep quality of medical staffs.
