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?
A . The operatives would be too careful and therefore would recommend unnecessary treatments or interventions.
B . Some callers may present with complicated scenarios that a non-medically trained operative or expert system would be unable to recognise (for example, psychological issues).
C . Using an expert system would make operatives less inclined to feel sorry for the caller and ensure that only relevant facts were considered in coming to a decision.
D . The use of an expert system would ensure that only relevant questions were asked of the caller and that operatives did not miss something vital due to distraction or fatigue.
E . The expert system will always follow the same path whereas the nurses may have more knowledge about some health issues and very little about others.
