Diabetes patient profiles


Profile 1




  • Shaun
  • 40 year-old male
  • Type 1 diabetes for 28 years
  • Currently on MDI
  • HbA1c of 9.1% (76mmol/mol), higher than his 7% (53mmol/mol) HbA1c target




The patient has been unable to control his blood glucose levels despite multiple daily injections and carbohydrate counting. He is frustrated because he is still not reaching his target and he is well aware that due to his elevated HbA1c he is at greater risk of developing diabetes-related complications.




The goal for the patient is to reach his target of 7% (53mmol/mol) HbA1c.


Continuous subcutaneous insulin infusion (CSII) can be a treatment option for adults with type 1 diabetes, if attempts to reach HbA1c target have failed with multiple daily injections (MDI).

Profile 2

Diabetes patient with Dawn phenomenon (hyperglycaemia)



  • Susan
  • 50 year-old Female
  • Type 1 Diabetes for 35 years
  • HbA1c 7.8% (61.mmol/mol)
  • MDI – long acting insulin once daily in the morning and rapid acting before meals




The patient reports experiencing high overnight fasting blood glucose levels on a regular basis and is becoming frustrated. Her early morning high BG reading makes her feel as though her day is ruined before it's begun. She would like greater control over her high blood glucose level because she is aware of the increased risk of long-term diabetes complications (Retinopathy, Nephropathy, Neuropathy etc).




The patient's goal is to obtain better control over her morning hyperglycaemia.


CSII is recommended for patients showing one of the following criteria: HbA1c ≥ 7% (53mmol/mol), recurring hypoglycaemia, repeated occurrence of the Dawn phenomenon, with overnight fasting blood glucose levels frequently exceeding 9mmol/L or history of severe glycaemic excursions4,5,6.

Profile 3

Diabetes patient with frequent hypoglycaemia



  • Richard
  • 32-year old male
  • Type 1 diabetes for 23 years
  • MDI – one injection of long acting insulin in morning and rapid acting insulin before meals
  • HbA1c 7.0% (53mmol/mol)




The patient experiences frequent hypoglycaemia during the day at least 3 times a week. The hypoglycaemia events usually occur after exercise. He has experienced severe low blood glucose level events, requiring third party assistance twice in the past 6 months.




The goal is to reduce the frequency of his hypoglycaemia and allow him to engage in sport more frequently - while obtaining good glycaemic control.

Treatment considerations

CSII is indicated in case of hypoglycaemia, or fear of low blood glucose level. Fear of hypoglycaemia, especially during the night, may compromise quality of life (QOL) for the family and jeopardize efforts to achieve optimal metabolic control5,7-11.

Profile 4

Diabetes patient with lifestyle changes


  • Maria
  • 34 year-old female
  • Type 1 diabetes for 18 years
  • HbA1c of 7.5% (58mmol/mol)
  • Currently on MDI
  • The patient started a new job 3 months ago. Half of her time will involve travelling across various time zones




The patient is concerned about maintaining blood glucose level when she travels. She is worried that she won’t be able to manage the frequent time zone changes and longer days combined with meal time disruption are also causing concern.




The patient’s goal is to achieve HbA1c control despite leading an unpredictable lifestyle.


CSII can benefit patients seeking a more flexible lifestyle, and improve the patient’s wellbeing11,14.
