We studied the use of stat (ie, statim--as soon as possible) laboratory tests at a university teaching hospital. For the 20 most frequently performed tests, 35.7% of the determinations were performed on a stat basis. The frequency with which a test was ordered on a stat basis ranged from 6.0% (for ESR) to 61.5% (amylase level). The proportion of laboratory test requests from a hospital service that were ordered stat ranged from 3.8% (orthopedic surgery) to 100% (emergency services). The daily number of regular laboratory test requests decreased significantly over the weekend, but the daily number of stat requests fell less sharply. The number of requests for routine tests decreased after 6 pm, but the number of requests for stat tests remained relatively constant until about midnight.
我们研究了一所大学教学医院即时（即statim，尽快）实验室检查的使用情况。对于20项最常进行的检查，35.7%的检测是按即时要求进行的。某项检查按即时要求开出的频率从6.0%（血沉）到61.5%（淀粉酶水平）不等。医院各科室要求进行实验室检查中按即时要求开出的比例从3.8%（整形外科手术）到100%（急诊服务）不等。周末常规实验室检查要求的每日数量显著减少，但即时要求的每日数量下降幅度较小。下午6点后常规检查的要求数量减少，但即时检查的要求数量直到午夜左右仍相对稳定。
