Experience with a hospital laboratory admission screen

A comprehensive laboratory admission screen can be instituted in any large laboratory but only in one in command of conventional technology and with the co-operation of the laboratory, medical, nursing and admitting staff.The capital equipment required is costly and subject to early obsolescence. The operating costs are initially high, but the influence of the screen on the general work load indicates that the total overall procedures ordered by the physician will be reduced in number and that over a three-year period, in an economy subject to continuous inflationary pressure, the total cost will approach what might have been expected had the screen not been instituted.By presenting, shortly after admission, a truly comprehensive laboratory profile, the total number of procedures ordered will be reduced and this reduction bears no relationship to whether or not the data supplied are medically useful.The equipment more recently available for a large admission screen is far superior, from the point of view of speed of assay and cost of maintenance and production, to the equipment that has been available to us in this study.It is believed that the unit cost of assay will continue to decline and that the principle of unsolicited testing will be expanded in the future to include procedures not presently in the profile.It is predicted that in the relatively near future almost all of the laboratory procedures that a clinician could conceivably request will have been done prior to his examination of the patient.
