Implementation of an on-line archive for retrieval of laboratory results for outpatients.

An on-line archive of laboratory results designed specifically for ambulatory care areas is described. It is a direct result of paper-flow problems in clinics, which were manifested by numerous phone calls to the laboratory for test results performed up to 10 months ago, and requiring as much as 30 minutes each for retrieval. The archive is incorporated into the result inquiry program of our laboratory computer and is transparent to the user. Utilization of this system by our personnel saves up to 12 hours of work each day. By capturing in a separate file the patient location of each call for outpatient results we are able to identify the clinics that use the telephone for retrieval of test results.
