  • Increased site resistance: If you notice that your insulin delivery is becoming less effective, or if you're experiencing frequent site failures.
  • Swelling or redness: If the site is becoming swollen, red, or inflamed, it may be a sign that the site is failing.
  • Pain or discomfort: If you experience pain or discomfort at the site, it may indicate a problem.

Step 2: Take Immediate Action

If you suspect that your insulin pump site is failing, take immediate action to minimize the impact:

  • Change the site: If possible, change the site immediately to a new location to maintain continuous insulin delivery.
  • Check your pump settings: Ensure that your pump is functioning correctly and that your basal rates and bolus doses are set accurately.
  • Consult with your healthcare provider: Reach out to your healthcare provider or diabetes educator for guidance and support.

Step 3: Assess and Address the Cause

To prevent future site failures, it's essential to assess and address the underlying cause:

  • Check your pump and site: Ensure that your pump and site are clean, dry, and free of any damage.
  • Review your insertion technique: Make sure that you're inserting the site correctly, following the manufacturer's guidelines.
  • Adjust your basal rates and bolus doses: If you've recently made changes to your basal rates or bolus doses, adjust them as needed to maintain optimal insulin delivery.

Step 4: Prepare for a New Site

To ensure a seamless transition, prepare for a new site:

  • Have a backup plan: Have a backup plan in place, including a spare pump or a temporary insulin delivery method, such as a syringe or pen.
  • Pack supplies: Make sure you have all the necessary supplies, including a new site, a pump, and any necessary accessories.
  • Schedule a follow-up: Schedule a follow-up appointment with your healthcare provider to discuss any concerns and receive guidance on preventing future site failures.

Step 5: Review and Adjust

After the site failure, take the opportunity to review and adjust your insulin delivery plan:

  • Review your pump settings: Ensure that your pump settings are accurate and optimized for your needs.
  • Adjust your basal rates and bolus doses: Make any necessary adjustments to your basal rates and bolus doses to maintain optimal insulin delivery.
  • Consider alternative delivery methods: If you experience frequent site failures, consider alternative delivery methods, such as a continuous glucose monitor (CGM) or an insulin patch pump.
