“…This is not surprising since the system described here asks only for features relevant to ovulation. The generally positive response is in accordance with various studies [18][19][20] performed in this and other units, virtually all of which confirm a high degree of consumer acceptance.…”

The use of an expert system shell (EXPERTECH Xi Plus) in the construction of an expert system for the diagnosis of infertility has been evaluated. A module was devised for predicting ovulation from the medical history alone. Two versions of this system were constructed, one using the expert system shell, and the other using QuickBASIC. The two systems have been compared with respect to: (1) ease of construction; (2) ease of knowledge base update; (3) help and explanation facilities; (4) diagnostic accuracy; (5) acceptability to patients and clinicians; (6) user-friendliness and ease of use; (7) use of memory space; and (8) run time. The responses of patients and clinicians were evaluated by questionnaires. The predictions made by the computer systems were compared to the conclusions reached by clinicians and to the “gold standard” of day 21 progesterone.The conclusions of this pilot study are: (1) the construction of this expert system was NOT facilitated by the use of this expert system shell; (2) update of the knowledge base was not facilitated either; (3) the expert system shell offered built-in help and explanation facilities, but as the system increased in complexity these became less useful; (4) after initial adjustment of decision thresholds the diagnostic accuracy of the system equalled that of the clinician; (5) the patient response to computer history-taking was very favorable but much less favorable to computer diagnosis; (6) the clinicians took a positive attitude to computer diagnosis; (7) the systems were easy to use; (8) the expert systems shell required much more memory space and had a much slower response time than the system written in BASIC.

“…Before the introduction of keynet, the programs were evaluated extensively from the point of view of time, amount and quality of information produced (by means of a crossover study), and patients' acceptance. 1 These have shown that: a. The average history takes 13 minutes, with an additional 3 -7 minutes for each previous delivery.…”

Use of a Microcomputer Network for History Taking in a Prenatal Clinic

A stand-alone microcomputer was installed at St. Bartholomew's Hospital to obtain the booking (first prenatal) history. This system has many well-documented advantages over the manual method, particularly with respect to the completeness and quality of the history produced. However, a single microcomputer system is unable to deal with the load of a busy clinic, and initially, several independent terminals were required. We now describe the installation of a local area network to link several microcomputers with a single database in the Antenatal Clinic at Queen Charlotte's Maternity Hospital.
