Chapter 1 Red flags of disease
In summary, referral may be considered for the following four broad reasons:
1. To enable the patient to have access to medical treatment which will benefit their condition.
2. For investigations to exclude the possibility of serious disease.
3. For investigations to confirm a diagnosis and help guide treatment.
4. For access to advice on the management of a complex condition.
The red flags as guides to referral
Red flags are guides to referral and not absolute indicators. Often the red flags described in this text specify a fixed, measurable point at which referral should be considered, for example high fever (especially if over 40°C) not responding to treatment within 2 hours in a child. Of course, in reality, disease falls somewhere along a spectrum which bridges the state of being of little concern and one of being of serious concern (see Figure 1.1). A disease does not suddenly become serious once a fixed point has passed. Moreover, what might constitute a red flag in one individual may be of less concern in someone of a stronger constitution.
Prioritisation of the red flags
*Non-urgent: A non-urgent referral means that the patient can be encouraged to make a routine appointment with the medical practitioner (GP) and this ideally will take place within 7 days at the most.
**High priority: A high priority referral means that the patient is assessed by a medical practitioner within the same day.
***Urgent: The urgent category is for those situations when the patient requires immediate medical attention, and this may mean summoning an on-call doctor or calling the paramedics to the scene.
