Computer-aided diagnosis of lower abdominal pain in women.

This paper describes the use of a system of computer aided diagnosis in an unselected, prospective survey of 393 women suffering from lower abdominal pain of less than 1 week's duration. An accurate diagnosis was made by clinicians at first patient contact in 68-5 per cent of the group of patients. The computer's diagnostic prediction (based on the same data) matched the final diagnosis in 81-6 per cent of the patients. During this survey a marked improvement in diagnostic accuracy was observed amongst the junior clinicians. It is suggested that this is because of the discipline of data collection imposed and the intermittent feedback received, and also that this educational aspect of computer usage may be of wider benefit.
