Usually LIS(Laboratory Information System) depend on OCS(Order Communication System) of HIS(Hospital Information System). So, both systems are constructed simultaneously. But it needs high cost and has potential of failure. So, we designed one combined laboratory request slip and isolated LIS(sever: Power Mac 7200, eight clients: LC 475, connected by Ethernet) operating with own order input system before HIS construction. we analyzed the efficiency during early 9 weeks (from Aug. 17 to Oct. 17 in 1995) and later 4 weeks (March in 1996). Daily input amount of request changed stably in the later period(maximum: 552. mean: 410.0) than the early period(maximum: 604. mean: 341.6). Peak time was between 9 a.m. and 10 a.m.(maximum: 127. slip/hour). In the later period, 64.2% the requests for in-patients were completed until 10 a.m. and the request for out-patients distributed more evenly. Majority of problems occurred, were delayed(25.5% in the early, 61.1% in the later period) or missed specimen(31.9% in the early, 22.9% in the later). Total number (26,309) of used requests was less than half of the calculated number(57,621) of previous laboratory slips.
