The impact of an instant pregnancy test kit on the operations of a major hospital casualty department.

The records of all patients on whom a casualty department pregnancy test was performed during the first 4 months of 1986 were retrospectively examined and compared with the records of all patients who in the first 4 months of 1987 had had an instant pregnancy test performed in the same casualty department, to determine the impact of such a kit on diagnostic accuracy, operative procedures and related economic factors. It was demonstrated that instant pregnancy testing significantly improved the accuracy of provisional diagnoses and appeared to help in reducing the number of surgical procedures performed. Furthermore, it was shown that a combination of careful clinical assessment plus the appropriate application of an instant pregnancy test kit could result in a cost saving to the hospital of over $41,000 per annum.
