- the importance of education for patients on immunosuppressants
- the importance of regular monitoring of the patient’s wellness as well as blood counts
- the importance of education for patients on the symptoms of a medical emergency and the actions to take, including out-of-hours and away from urban centres and when to attend a hospital emergency department
- patient age as a risk factor for leukopenia, and that patient age should be taken into consideration in any clinical guidelines on TPMT testing
- diagnosis of sepsis and its management.
