Laboratory utilization by clinician specialty groups serving outpatients was monitored before and after requisition redesign. Requisition changes were designed to address compliance and utilization issues and included implementation of test groupings and cascades or ordering algorithms. Data collected included the number of selected tests and test sets ordered during both time intervals and the number of patient office visits. Selected tests for monitoring included CBC counts, metabolic panels, thyroid function tests, hepatic function tests, urine analysis, and send-out testing. Statistical significance was measured using Poisson rates for test ordering. The composite effect was a significant decrease in the overall number of tests ordered per outpatient visit for most specialties, with a shift in ordering practices from panels to individual tests. Utilization rates by specialty groups were characterized by average number of laboratory tests ordered per patient visit.
在申请单重新设计前后，对为门诊患者服务的临床医生专业组的实验室利用情况进行了监测。申请单的更改旨在解决合规性和利用问题，包括实施测试分组、级联或订购算法。收集的数据包括两个时间段内订购的选定测试和测试集的数量以及患者门诊就诊次数。用于监测的选定测试包括全血细胞计数、代谢指标、甲状腺功能测试、肝功能测试、尿液分析和外送检测。使用泊松率来衡量测试订购的统计显著性。综合效果是，大多数专科门诊患者每次就诊订购的测试总数显著减少，订购方式从组合测试转向单项测试。专业组的利用率以每位患者就诊订购的实验室测试平均数量为特征。
