Laboratory Information System using One Combined Request Slip: Specimen Requisition and Order Input System / 대한의료정보학회지

ABSTRACT

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.
