Healthcare Technology and Patient Monitoring

At previous meetings of the A.A.C.B. we have reported on some of the problems encountered in using CentrifiChem for routine work. The current report is concerned with our continuing experience, making particular reference to machine modifications initiated by the Electronics Department of this Hospital now that a significant part of the routine is being processed by CentrifiChem. Maintenance and adjustment of the system in-house over a 2-yr period has resulted in data accumulation which has been useful in predicting system malfunctions and failure modes, and the magnitude and source of errors. As a result a maintenance quality control programme has been initiated to highlight problems before they become grossly manifest. Hardware and software development is proceeding locally (within the Hospital) to upgrade the system in terms of accuracy, precision and reliability. Tests have been divided into 2 groups: 1. Urea, Creatinine, Cholesterol; 2. Protein, Albumin, GOT, GPT, CK, Alkaline Phos., γGT, all tests in a particular group being done whenever I or more of that group is requested. Group 1 tests require a total volume of 65 μl Group 2 120 μl sample; these amounts are well within reason when dealing with infants and children. The results obtained by CentrifiChem have been compared with those obtained by the standard manual techniques used in the laboratory. Now that CentrifiChem has been installed in many laboratories throughout Australia, there is a strong case for the publication or at least dissemination of comparable data.
