Insulin Pump Therapy Indications and Criteria

Automated insulin delivery (AID) systems should be the preferred insulin delivery method for youth and adults with type 1 diabetes who are capable of using the device, as they improve glycemic outcomes and reduce hypoglycemia. 1

Primary Indications by Diabetes Type

Type 1 Diabetes (Strongest Evidence)

For patients with type 1 diabetes, insulin pump therapy (preferably AID systems) is indicated when:

  • Uncontrolled A1C despite multiple daily injections (MDI) - This is the most evidence-based indication, with pumps showing modest A1C reductions of approximately 0.30% compared to MDI 1

  • Severe hypoglycemia or high glucose variability - Even if A1C goals are met, recurrent severe hypoglycemia is a strong indication, with pump therapy reducing severe hypoglycemia rates from 12.1 to 5.8 per 100 patient-years 2, 3

  • Dawn phenomenon - Particularly common in adolescents (32% of pump starts in 10-14 year olds), where adjustable basal rates can address early morning hyperglycemia 3

  • Young children under 7 years - Pump therapy is the preferred mode due to insulin sensitivity and unpredictable eating patterns 1

Type 2 Diabetes (Emerging Indication)

For patients with type 2 diabetes on MDI:

  • Insulin pump therapy should be offered when poor glycemic control persists despite intensive insulin therapy, oral agents, other injectable therapy, and lifestyle modifications 1, 2
  • One AID system has recently been FDA-approved for type 2 diabetes 1

Essential Prerequisites (Critical Safety Requirements)

Before initiating pump therapy, patients must demonstrate:

  1. Adequate diabetes self-management education - Non-negotiable foundation 4

  2. Adequate trial of flexible insulin therapy with modern analogues - Must document failure of optimized MDI regimen 4

  3. Evidence of active, safe diabetes self-management - Including consistent blood glucose monitoring and appropriate insulin adjustment 2

  4. Willingness and ability to use the device - Either independently or with caregiver support 2

Hierarchical Priority Framework

The Alberta Provincial Program established a useful 4-tier hierarchy 4:

Tier 1 (Highest Priority - Clear Benefit):

  • Problematic hypoglycemia
  • Inability to achieve acceptable control despite optimized MDI
  • Progressive complications

Tier 2 (Strong Indications):

  • Unpredictable activity levels
  • Dawn phenomenon
  • Children for whom MDI is inappropriate

Tier 3 (Patient-Centered):

  • Individual preference for lifestyle flexibility
  • Improved quality of life and satisfaction

Tier 4:

  • Clinical exception cases requiring expert review

Device Selection Algorithm

Current standard (2025): AID systems are preferred over non-automated pumps for type 1 diabetes 1

Choice should be based on:

  • Individual circumstances and preferences
  • Caregiver availability if needed
  • Specific clinical needs (e.g., tubed vs. tubeless/patch pumps)
  • Integration with continuous glucose monitoring (CGM) - pump therapy should preferably be offered with CGM 1

Common Pitfalls to Avoid

Critical safety concern: Risk of diabetic ketoacidosis with pump malfunction or disconnection - requires specialized interdisciplinary team available for emergencies 5

Patient selection errors:

  • Starting pumps without adequate MDI trial first
  • Insufficient patient education and training
  • Lack of ongoing support infrastructure 2
  • Not ensuring patient commitment to frequent monitoring

Access considerations: Patients already using continuous subcutaneous insulin infusion (CSII) should have continued access across third-party payors 1

Age-Specific Considerations

Infants/toddlers (0-4 years): Reduction of hypoglycemia is the primary indication (42.5% of cases) 3

School-age (5-9 years): Mixed indications including hypoglycemia reduction and improved control

Adolescents (10-19 years): Dawn phenomenon and lifestyle flexibility are predominant reasons 3

Older adults: Should have equal access to pump therapy as younger patients, based on shared decision-making 1

Contraindications

Absolute contraindications include:

  • Inability to perform basic diabetes self-management
  • Lack of caregiver support when patient cannot independently manage device
  • Unwillingness to monitor glucose appropriately
  • Severe visual impairment without trained caregiver assistance 6
