Evaluation of automated multiphasic health testing in the survey of the north-west region of Melbourne.

The results of automated multiphasic health testing (AMHT) in a randomly selected population of 664 subjects are reported. AMHT revealed a number of conditions that had not been diagnosed previously. A total of 535 newly diagnosed conditions in 301 patients could be attributed to the survey. The yield of new diagnoses by AMHT was not affected by previous surgery attendance or by attendance intervals. Follow-up over one year revealed that treatment was recommended for 342 of the 535 newly diagnosed conditions and that the response was satisfactory in 189 (55%), but the "uncertain" response of 124 (36%) should be investigated by more thorough follow-up in future projects. It is concluded that AMHT is beneficial because of the amount of information that is revealed, because of the financial value and because of the benefit to patients.
