Catchlove, BR, Wilson, RM, Spring, S & Hall, J 1979, 'Routine investigations in elective surgical patients. Their use and cost effectiveness in a teaching hospital', Medical Journal of Australia, vol. 2, no. 3, pp. 107-110.
An analysis of the utilization of diagnostic services in a group of 91 patients who were admitted to a teaching hospital for routine surgery is presented. The results indicate a very high utilization of services - 55% of patients had an ECG, 87% of patients had a chest X-ray examination, 93% of patients had a biochemical profile and 94% of patients had a full blood count performed at least once during their stay in hospital. The total costs (calculated on standard charges) for diagnositc tests were $4317.80 ($47.44 per patient). The majority of the tests were performed preoperatively, and no operation was cancelled, or even postponed, because of the result of investigations.
