Evaluation of automated multiphasic health testing of referred patients by general practitioners.

Seventy-eight general practitioners provided clinical follow-up reports on 752 patients whom they had referred to the Shepherd Foundation, Melbourne, for automated multiphasic health tests (AMHT). One or more new diagnoses were reported in 270 cases (36%). The yield of new diagnoses made as a result of AMHT was a function of sex, but not of age or pre-referral status. Additional useful information relevant to a previously known diagnosis was reported in 234 cases (31%) and other benefits in 185 cases (25%). Patients were significantly reassured in 623 cases (83%) while disadvantages were reported in 41 cases (5%).
