STUDY OBJECTIVES:To determine the total number of active sleep laboratories in the United States and the number of polysomnograms conducted on a yearly basis in these laboratories. METHODS:All members of the AASM and all AASM accredited sleep laboratory directors received a questionnaire addressing their laboratory and its volume. In three states, multiple telephone calls to AASM members were used to correctly identify the absolute number of labs and their PSG volume in those states. Extrapolating from the number of labs studies identified per questionnaire relative to the correct number (per calls) in those states and, then applying this ratio to the entire US, the total number of labs and studies was determined. RESULTS:Our data suggests that there are, in the year 2001, 1,292 sleep laboratories conducting 1,165,135 polysomnograms per year. This comes to 427 PSG's/year per 100,000 population in the United States. CONCLUSIONS:These data suggest that there are a relatively large number of sleep laboratories in the US conducting a substantial number of PSG's. However, there was considerable variability in this volume between states that did not relate to known markers of healthcare utilization. These numbers have likely increased since 2001.

研究目的:确定美国活跃睡眠实验室的总数以及这些实验室每年进行的多导睡眠图的数量。
方法:所有AASM成员和所有AASM认可的睡眠实验室主任均收到了一份有关其实验室及其数量的问卷。在三个州中,使用多次致电AASM成员的电话来正确标识实验室的绝对数量及其在这些州中的PSG量。从每个调查表中确定的实验室研究数量相对于这些州的正确数量(每次呼叫)进行推断,然后将该比率应用于整个美国,即可确定实验室和研究的总数。
结果:我们的数据表明,在2001年,有1,292个睡眠实验室每年进行1,165,135项睡眠监测。在美国,每10万人中有427个PSG /年。
结论:这些数据表明,美国有相对大量的睡眠实验室在进行大量的PSG。但是,与已知的医疗保健利用指标无关,各州之间的容积存在很大差异。自2001年以来,这些数字可能有所增加。
