S Doc is an out-of-hours service provided by a country's government. The service allows members of the public to call and speak to a nurse who can advise on medical situations which are not obviously emergencies. Depending on the situation the caller can be referred to the full emergency services, or be advised to go to Accident and Emergency at the nearest hospital. Alternatively, a callout from a general practitioner (GP) can be organised; the caller can be advised of where GP services are available; advice can be given over the phone; or a decision can be taken that no further action is required at least until normal services resume on the next working day.
There has been a suggestion that the nurses who take these calls could be replaced by suitably trained operatives who have available to them a specially designed expert system.
Which of the following are advantages of using an expert system instead of nurses?
