During five consecutive administrative periods, a computer data bank was set up from informations written on laboratory forms requesting tests in microbiology. A total of 13,260 forms were received and 11,591 were included in our study. 7,010 tests (60%) were requested from medical specialties; 40% of these tests were from patients admitted on hematology and on pediatrics wards. Of the 4,581 remaining tests, 36% were ordered for patients admitted on general surgery and on ophthalmology wards. Medical patients had three times as much blood cultures requested than surgical patients. The numbers of urine cultures done for medical and surgical patients were however similar (1,832 and 1,699 respectively). The average cost for microbiology cultures was twice as much in medical than in surgical patients. Such analysis of prescribing profile for laboratory tests provides useful information for the diagnosis related groups (DRG) system and can allow for a more efficient distribution of hospital resources.
在连续五个管理期间，根据微生物学检验申请单上填写的信息建立了一个计算机数据库。共收到13260份申请单，其中11591份纳入我们的研究。7010项检验（60%）来自医学专科；这些检验中有40%来自血液科和儿科病房收治的患者。在其余4581项检验中，36%是为普通外科和眼科病房收治的患者开具的。内科患者的血培养申请量是外科患者的三倍。然而，内科和外科患者的尿培养数量相似（分别为1832例和1699例）。微生物培养的平均费用在内科患者中是外科患者的两倍。对实验室检验处方概况的此类分析为诊断相关分组（DRG）系统提供了有用信息，并有助于更有效地分配医院资源。
